Active travel to school and cardiovascular fitness in Danish children and adolescents.

PURPOSE: Active travel to school provides an opportunity for daily physical activity. Previous studies have shown that walking and cycling to school are associated with higher physical activity levels. The purpose of this study was to investigate whether the way that children and adolescents travel to school is associated with level of cardiovascular fitness. METHODS: Participants were recruited via a proportional, two-stage cluster sample of schools (N = 25) in the region of Odense, Denmark as part of the European Youth Heart Study (EYHS). Nine hundred nineteen participants (529 children, age 9.7 +/- 0.5 yr; 390 adolescents, age 15.5 +/- 0.4 yr) completed a maximal cycle ergometer test to assess cardiorespiratory fitness (Wmax x kg(-1)). Mode of travel to school was investigated by questionnaire. Physical activity was measured in 531 participants using an accelerometer. Regression analyses with robust standard errors and adjustment for confounders (gender, age, body composition (skinfolds), pubertal status, and physical activity) and the cluster sampling procedure were used to compare fitness levels for different travel modes. Multinomial logistic regression was applied to assess the odds for belonging to quartiles of fitness. RESULTS: Children and adolescents who cycled to school were significantly more fit than those who walked or traveled by motorized transport and were nearly five times as likely (OR 4.8; 95% CI 2.8-8.4) to be in the top quartile of fitness. CONCLUSION: Cycling to school may contribute to higher cardiovascular fitness in young people.

[Effect of exercise habits and lifestyles on changes in physical fitness in medical college students: a 3-year follow-up study].

This follow-up study investigated the relationship between changes in physical fitness and exercise habits during the 1st and 4th years in healthy medical college students. We also investigated the relation between exercise habits and the lifestyle factors during the same period of time. The subjects were 229 male and 126 female student volunteers who received physical fitness tests and questionnaires (lifestyles and exercise habits) in both the 1st and 4th years. The results were as follows: 1. A significant association between increment in physical fitness and exercise habits was shown by the fitness score in the 1st year, and the intensity and frequency of exercise in the 4th year in males. In females, an association was found in the intensity of exercise during the 1st year, and frequency of exercise during the 4th year. The intensity in 4th year among males (odds ratio(OR): 2.80, 95% confidence interval (CI): 1.33-5.87) and the frequency during the 4th year among females (OR: 5.63, 95% CI: 2.36-13.43) were associated with a higher odds ratios for improvement in physical fitness than other factors related to exercise habits in 4th year medical students. 2. In the association between exercise habits related to increment in physical fitness and other lifestyles, a significant association was admitted between the intensity of exercise and the frequency of eating breakfast during the 4th year in males (OR: 2.18, 95% CI: 1.11-4.28). These results suggested that the intensity of exercise during the 4th year in males and the frequency of exercise during the 4th year in females were associated with increments in physical fitness for follow-up. A lifestyle factor related to the intensity in exercise habits has been suggested to be the frequency of eating breakfast (more than 5 days/week) in males.

Enhancing brain and cognitive function of older adults through fitness training.

The present article provides a brief review of the human and animal literature that has investigated the relationship between fitness training and brain and cognitive function. The animal research clearly suggests that improvements in fitness can lead to both morphological and functional changes in the brains of older animals. Results of a recent meta-analysis suggest that fitness training can also have beneficial effects on human cognition, particularly on tasks requiring executive control processing. These effects are also moderated by a number of factors, including the proportion of men and women in the intervention studies, the length of training sessions, the age of the participants, and the combination of fitness training regimes. The article also discusses preliminary results that link, for the first time, fitness training and differences in human brain structure and function. Finally, we discuss the important issue of participant adherence to fitness training programs and the factors that influence fitness participation.

Seasonal variation in fitness parameters in competitive athletes.

In many sports, training for successful competition has become virtually a year-round endeavour. To assist in better preparation, a competitor's year may be divided into phases such as off-season and in-season, indicating reduced or increased competition commitments, respectively. A number of studies have described the effects of seasons or periods of competition, training, detraining and reduced training on aspects of physical fitness. Depending on performance level, the type of sport and the fitness parameter in question, the swings in fitness variables reported may be as high as 18% from one season to another. In elite competitors, anaerobic parameters, heart frequencies, subcutaneous fat, flexibility and haemoglobin levels remain relatively unchanged throughout the year. Aerobic metabolism and muscular strength may demonstrate noticeable (mostly unfavourable) changes, and plasma hormonal levels normally follow changes in training intensities. Aspects related to long term fatigue and genetics, and to appropriate training are just a few explanations for these observations. It is still not known whether greater fitness gains attainable with longer off-season training programmes can be successfully maintained over the duration of the competition season. However, the consensus would seem to be that specialised training (based on technique and competition tactics only) is inadequate for fitness maintenance and/or improvements. This is perhaps supported by the general trends found in the literature regarding muscular strength: while supervised off-season conditioning programmes may result in significant improvements for both recreational and competitive athletes, no such changes are normally observed after competition seasons. These findings may reflect, amongst other factors, a lack of optimal training intensity to bring about strength increases during in-season periods. In novices and in athletes at low competitive levels, training seasons may lead to considerable functional improvements of the cardiorespiratory system, coupled with occasional increases in muscular strength and decreases in body fat. Relatively low fitness levels at the beginning of training have been put forward as an explanation for these improvements. Seasons of training and competition result in no significant changes in flexibility measurements. Similar changes to those found in novices and in athletes at low competitive levels may also be seen in children and adolescents engaged in sport, although their fitness improvements are consistent with normal patterns of growth and development. No differences have been identified between male and female athletes participating at different competition levels.

Physical activity, physical fitness, and insulin and glucose concentrations in an isolated Native Canadian population experiencing rapid lifestyle change.

OBJECTIVE: Little is known about the relation of physical activity and physical fitness to insulin resistance and glucose intolerance in isolated subarctic Native Canadian populations. The purpose of this effort was to examine the relation between activity and fitness and obesity and glucose concentrations in such a unique population. RESEARCH DESIGN AND METHODS: This study describes 530 men and women from the community of Sandy Lake, Ontario, located in the boreal forest region of central Canada. Fasting blood glucose and insulin concentrations were determined after an overnight fast. Past year physical activity levels were assessed using a modified version of an interviewer-administered questionnaire. Maximal oxygen uptake, a measure of cardiovascular fitness, was estimated using a submaximal step test. RESULTS: Total (leisure and occupational) physical activity and physical fitness were significantly associated with fasting insulin concentrations after adjusting for age, BMI or percent body fat, waist circumference, and fasting glucose concentration in men but not in women. The relations between physical activity, fitness, and fasting glucose concentrations were not as strong or as consistent as they were when fasting insulin concentration was the dependent variable. CONCLUSIONS: In this isolated Native Canadian community, both physical activity and fitness were independently associated with fasting insulin concentrations, suggesting a beneficial role of physical activity/fitness on insulin sensitivity that is separate from any influence of activity on body composition. The fact that this relation was found in men but not in women is most likely explained by issues related to the measurement of activity and fitness in this study and the fact that the women in this population appear to be less active than the men.

Features of the metabolic syndrome are associated with objectively measured physical activity and fitness in Danish children: the European Youth Heart Study (EYHS).

OBJECTIVE: Features of the metabolic syndrome are becoming increasingly evident in children. Decreased physical activity is likely to be an important etiological factor, as shown previously for subjective measures of physical activity in selected groups. The purpose of this study was to examine the relationship between the metabolic syndrome and objectively measured physical activity and whether fitness modified this relationship. RESEARCH DESIGN AND METHODS: A total of 589 Danish children (310 girls, 279 boys, mean [+/-SD] age 9.6 +/- 0.44 years, mean weight 33.6 +/- 6.4 kg, mean height 1.39 +/- 0.06 m) were randomly selected. Physical activity was measured with the uni-axial Computer Science & Applications accelerometer (MTI actigraph) worn at the hip for at least 3 days (>/=10 h/day) and fitness with a maximal bike test. As outcomes, we measured sitting systolic and diastolic blood pressure, degree of adiposity (sum of four skinfolds), and, finally, insulin, glucose, triglicerides, and HDL cholesterol in fasting blood samples. The outcome variables were statistically normalized and expressed as the number of SDs from the mean. (i.e., Z scores). A metabolic syndrome risk score was computed as the mean of these Z scores. Multiple linear regression was used to test the association between physical activity and metabolic risk, adjusted primarily for age, sex, sexual maturation, ethnicity, parental smoking, socioeconomic factors, and the Computer Science & Applications unit, as well as for fitness. Robust SEs were computed by clustering on school. RESULTS: All children were in the nondiabetic range of fasting glucose. Metabolic risk was inversely related to physical activity (P = 0.008). The relationship was weakened after adjustment for fitness, but there was a significantly positive interaction between physical activity and fitness. CONCLUSIONS: Physical activity is inversely associated with metabolic risk, independently of potential confounders. The interaction between physical activity and fitness suggests that the potential beneficial effect of activity may be greatest in children with lower cardiorespiratory fitness.

Relationship between cardiorespiratory fitness and physiological responses to films.

Subject's physiological responses and rated reactions to a medical film and an erotic film were assessed. Later cardiovascular fitness levels were determined by subject's physiological responses to an exercise task. The greater the increase in the subject's systolic blood pressure after exercise and the slower the recovery, the lower the fitness level. A median split on the fitness scores of males and females separately was used to determine levels of relatively low and high fitness. Subjects in low fitness had significantly greater sympathetic-arousal responses to the two films as measured in systolic blood-pressure increases and skin-temperature decreases. Subjects in the two fitness levels did not differ in ratings of their own physiological or emotional responses to the films. Reported interoception of the magnitude of physiological responses was inaccurate, especially for subjects in low fitness.

Effectiveness of a personalized fitness module on knowledge, attitude, and cardiovascular endurance of fifth-grade students: "heart smart".

The effectiveness of a Personalized Fitness Module was compared to a Traditional Fitness Unit, both of which were designed to develop knowledge, behavioral skills, fitness and positive attitudes. 95 students in Grade 5 and from intact physical education/health classes within two public schools participated in a seven-week cardiovascular fitness program. The experimental group of 48 participated in the personalized and noncompetitive fitness module. The control group of 47 participated in the traditional unit, a teacher-centered fitness module. Students received a total of 14 55-min. lessons over seven weeks. Pre- and posttest measurements included the Superkids-Superfit Knowledge Test, the Children's Attitudes Toward Physical Activity Inventory, and the one-mile run/walk. Data were analyzed using group mean gain scores on eight dependent variables (knowledge, six subscales of attitude, and one-mile run/walk) followed by a multivariate analysis of variance. A significant difference between groups led to a discriminant function analysis as a post hoc test. Findings indicated that the use of the personalized unit can substantially improve one-mile run/walk time. The use of modules of this type in health and physical education programs may promote life-long exercise patterns and fitness.

Physical fitness and self-reported physical exercise among college men and women in 1987 and 1997.

The study examined the relations of self-reported physical activity levels and physical fitness scores for two samples of college students assessed in 1987 (n = 261) and in 1997 (n = 243). Significantly greater exercise was reported by the 1997 women than the 1987 women; amount of exercise reported by men did not differ. For both samples, greater exercise was associated with increased fitness for women and men as assessed by the Hall 1986 Physical Fitness Test Profile, comprised of measures on body fat composition; grip strength; muscle endurance, flexibility, resting heart rate; systolic and diastolic blood pressures; and aerobic power. For the 1987 sample men were more fit than women. For the 1997 sample, women were more fit than men. The 1997 women were more fit than the 1987 women; there was no difference on overall fitness measures of the two samples of men.

The relation between aerobic fitness and serum cholesterol levels in a large employed population.

BACKGROUND: The purpose of this epidemiologic study was to determine the extent to which aerobic fitness was associated with total cholesterol/HDL-C ratios greater than 5.0 in 10,455 adults. The confounding effects of age, gender, income, body fat, smoking, and alcohol use were also examined. METHODS: A step test was used to estimate aerobic fitness, and serum cholesterol was measured in a certified lab. Lifestyle information was gathered using written questionnaires, and body fat was assessed using skinfold measurements. RESULTS: High fitness levels were associated with low prevalence of elevated total/HDL-C ratios. After controlling for the potential confounders, adults classified as having excellent, very good, good, or fair aerobic fitness levels were .46, .64, .61, and .85 times as likely to have elevated ratios compared to poorly fit adults, respectively. High-level fitness was also related to high HDL-C levels and low total cholesterol levels. DISCUSSION: Cause-and-effect conclusions are not warranted; however, poorly fit adults appear to be at increased risk of elevated levels of serum cholesterol.

Fitness, performance, and risk of injury in British Army officer cadets.

The objectives of this study were to investigate the effectiveness of the Commissioning Course (CC) to develop and maintain standards of fitness, to assess capability to perform military tasks, and to determine the relationship between fitness and risk of injury in 106 British Army officer cadets (OCdts). Aerobic fitness, muscular strength, endurance, and body composition were regularly assessed. Performance on four representative military tasks was measured at the end of the CC. All injuries in term 1 were documented. Over the CC, changes in fitness were generally modest and equivocal. Aerobic fitness improved by approximately 10% (p < 0.01), strength by 5 to 9% (p < 0.05 to p < 0.01), and muscular endurance by 55% (p < 0.01). Reductions in fat (p < 0.01) and gains in fat free mass (p < 0.05) averaged 3%. The females demonstrated greater improvements than the males. The majority of OCdts passed the representative military tasks, although females in some trades showed high failure rates. Forty-six percent of OCdts sustained injuries in the first term, resulting in 5% of man-days lost. No gender difference was found in injury rates. The least aerobically fit OCdts sustained more injuries than their fitter counterparts. In conclusion, there is scope for optimizing the effectiveness of the CC to enhance fitness and improve the focus of physical training on maximizing military task performance.

Saskatchewan physicians' attitudes and knowledge regarding assessment of medical fitness to drive.

BACKGROUND: Although legislation has been introduced in Saskatchewan for mandatory reporting by physicians of patients considered medically unfit to drive, little is known about physicians' attitudes, knowledge or resources with regard to evaluating medical fitness to drive. METHODS: The objective of this study was to determine Saskatchewan physicians' attitudes, knowledge, training, resources and current educational needs with regard to evaluating medical fitness to drive. A questionnaire survey of all physicians in the province who were identified as likely to be involved in determining medical fitness to drive was conducted between October and December 1996. RESULTS: Of the 1102 physicians who received a questionnaire, 690 (62.6%) responded, of whom 167 were excluded because they were not involved in assessing fitness to drive. Thus, 523 (55.9%) of the 935 eligible physicians surveyed completed the questionnaire. Most (57.6% [298/517]) of the respondents indicated that they do not hesitate to report patients medically unfit to drive; however, 59.5% (307/516) felt that the physician-patient relationship is negatively affected by reporting. Overall, 85.5% (444/519) of the respondents felt that restricted licensing is a fair alternative for people who might otherwise be denied a full licence. The availability of restricted licensing positively influenced the decision to report for 60.3% (313/519) of the respondents. Significantly more rural physicians than urban physicians believed that the need to drive was greater for rural residents than for urban dwellers (81.2% [95/117] v. 64.2% [257/400], p < 0.001). Physician knowledge regarding specific medical conditions and fitness to drive was generally poor. The resource most commonly used in determining medical fitness to drive was the Physicians' Guide to Driver Examination (71.1% [361/508] of respondents). The most useful continuing medical education methods indicated by physicians for assessing medical fitness to drive included conference presentations, workshops and journal articles. INTERPRETATION: Most of the Saskatchewan physicians surveyed supported restricted licensing, and the availability of restricted licensing made them more likely to report patients considered medically unfit to drive. The physician-patient relationship was felt to be negatively affected by reporting.

Contact lens fitting difficulties following refractive surgery for high myopia.

PURPOSE: To describe the clinical and optical problems encountered in contact lens fitting following refractive surgery for high myopia. METHODS: Following refractive surgery for high myopia (greater than -10.00 D) we corrected residual refractive errors with contact lenses in the four eyes of two patients. The first patient had undergone bilateral laser in situ keratomileusis (LASIK),with two subsequent LASIK retreatments in the left eye. Ten months later she was fit with rigid gas permeable (RGP) lenses in both eyes. The second patient had undergone a clear lens extraction in the right eye and radial keratotomy followed by photorefractive keratectomy(PRK) in the left eye. She was fit with toric soft lenses six years postoperatively. RESULTS: Final visual acuity obtained with contact lenses was 20/25-20/20 in all eyes. The first patient required significant minus lens power compensation. Furthermore, the RGP lens in the left eye was slightly decentered due to corneal irregularity induced by LASIK. The second patient had regular corneal surfaces and was successfully fit with daily wear toric soft lenses despite the 2.75 D of residual astigmatism in the left eye. CONCLUSIONS: Following refractive surgery for high myopia a proportion of patients will remain undercorrected. In these patients the alterations in corneal architecture that ensue make contact lens fitting more challenging. Patients with regular astigmatism may be fitted successfully with toric soft lenses. Patients with corneal irregularities should be fit with RGP lenses.

Adiposity does not hinder the fitness response to exercise training in obese women.

BACKGROUND: This study examined how sedentary obese (OB) and normal weight (NW) women respond to exercise training; and if fitness levels of the OB and NW are comparable, in spite of differences in adiposity. METHODS: Sedentary OB (n=46, 48.5+/-1.5 yrs, BMI=35.9+/-0.8; mean+/-SEM) and NW (n=43, 48.3+/-1.7 yrs, BMI=21.7+/-0.2) women participated in a 14-week fitness program. RESULTS: There were no group differences in exercise adherence. No changes for either group were found for body weight or composition. Both groups improved similarly in aerobic fitness (VO2max), muscular strength (grip strength), muscular endurance (modified push-up), and flexibility (sit and reach). However, since norms for fitness are generally expressed relative to body weight (e.g. VO2max, ml x kg(-1) x min(-1); grip strength ratios), the OB women continued to be classified as unfit after exercise training, and categorized below the NW women in spite of having absolute scores for VO2max (OB=2.1+/-0.1, NW=1.8+/-0.1 l x min(-1)) and grip strength (OB=65.1+/-1.5, NW= 58.6+/-1.5 kg) that were higher than the NW women. CONCLUSIONS: The data suggest that OB women respond in a similar manner as NW women to exercise; that weight loss is not necessary for improved fitness; and that the OB are not less fit than the NW, but that low fitness scores for the OB are simply a reflection of the absolute scores being deflated because they are proportioned to body weight.

[Assessment of physical activities from functional physical fitness tests research for patients with chronic obstructive pulmonary disease].

The purpose of this study was to determine whether the level of physical activity (as measured by 12 functional physical fitness tests) differed between patients with chronic obstructive pulmonary disease (COPD) and normal subjects. Fifty male patients with COPD (70.4 +/- 7.1 yr) and 193 age-matched normal subjects (71.2 +/- 5.2 yr) participated in the study. We administered twelve functional physical fitness tests that were designed to represent muscle strength, muscular endurance, reaction, flexibility, balance, regulation and manipulation. Cardiorespiratory fitness was measured by an incremental, symptom-limited exercise test to the maximal tolerable level on a cycle ergometer, and by the 6-min walk distance. Further, we evaluated what the relationships were between cardiorespiratory fitness and physical activities. The results showed that there were significant differences between COPD and normal groups in cardiorespiratory fitness [peak oxygen uptake (15.7 +/- 4.8 ml/kg/min vs. 23.9 +/- 6.5 ml/kg/min, p < 0.05), peak load (77.9 +/- 33.7 watts vs. 110.3 +/- 37.9 watts, p < 0.05) and 6-min walk distance (466.4 +/- 106.3 m vs. 540.4 +/- 78.3 m, p < 0.05)] and muscular endurance [arm curl (22.6 +/- 5.0 rep/30 s vs. 25.2 +/- 6.0 rep/30 s, p < 0.05), Keeping a half-squat position (32.6 +/- 16.4 s vs. 42.8 +/- 17.7 s, p < 0.05)] and regulation (27.2 +/- 9.4 s vs. 23.3 +/- 5.8 s, p < 0.05) in functional physical fitness test. There were significant correlations between cardiorespiratory fitness, and muscular endurance and regulation. Furthermore, there were significant correlations between FEV1.0 and FEV1.0% pred, and regulation. Therefore, it is important that, besides exercise prescriptions based on the criteria of symptom-limited exercise tests, development of exercise programs based on the level of physical activities may be necessary for patients with COPD.

A randomized clinical trial comparing fitness and biofeedback training versus basic treatment in patients with fibromyalgia.

OBJECTIVE: To compare the therapeutic effects of physical fitness training or biofeedback training with the results of usual care in patients with fibromyalgia (FM). METHODS: One hundred forty-three female patients with FM (American College of Rheumatology criteria) were randomized into 3 groups: a fitness program (n = 58), biofeedback training (n = 56), or controls (n = 29). Half the patients in the active treatment groups also received an educational program aimed at improving compliance. Assessments were done at baseline and after 24 weeks. The primary outcome was pain [visual analog scale (VAS)]. Other endpoints were the number of tender points, total myalgic score (dolorimetry), physical fitness, functional ability (Arthritis Impact Measurement Scale and Sickness Impact Profile), psychological distress (Symptom Checklist-90-Revised), patient global assessment (5 point scale), and general fatigue (VAS). RESULTS: Baseline scores were similar in all 3 groups. Altogether 25 (17.5%) patients dropped out; they were similarly distributed over all groups: 14 patients after randomization and 11 (8%) during the study. A true high impact level for fitness training was not attained by any patient. After treatment, no significant differences in change scores of any outcome were found between the groups (ANOVA, p > 0.05). All outcome measures showed large variations intra- and interindividually. The educational program did not result in higher compliance with training sessions (62% vs 71%). Analysis of the subgroup of subjects with a high attendance rate (> 67%) also showed no improvement. CONCLUSION: In terms of training intensity and maximal heart rates, the high impact fitness intervention had a low impact benefit. Therefore effectiveness of high impact physical fitness training cannot be demonstrated. Thus compared to usual care, the fitness training (i.e., low impact) and biofeedback training had no clear beneficial effects on objective or subjective patient outcomes in patients with FM.

High or low intensity aerobic fitness training in fibromyalgia: does it matter?

OBJECTIVE: To determine the efficacy of training in fibromyalgia (FM), we compared the effects of high intensity fitness training (HIF) and low intensity fitness training (LIF). METHODS: Thirty-seven female patients with FM were randomly allocated to either a HIF group (n = 19) or a LIF group (n = 18). Four patients (1 HIF group, 3 LIF group) refused to participate after randomization but before the start of the intervention. They were excluded from the analysis. Assessments were performed at baseline and after 20 weeks of HIF or LIF. The primary outcome was patient's global assessment [on 100 mm visual analog scale (VAS)]. Secondary endpoints were pain, number of tender points, total myalgic score, physical fitness, health status, and psychological distress. RESULTS: One patient in the HIF group (n = 18) and 2 in the LIF group (n = 15) stopped training sessions during the course of the study. Nine of 18 patients in the HIF group compared to 8 of 15 patients in the LIF group achieved a participation rate of 67% or more. Most important reasons for nonadherence were postexercise pain and fatigue, time consumption, and stress. The VAS for global well being improved slightly from 64 to 56 mm in the HIF group, and did not change in the LIF group (58 to 61 mm) (p = 0.07). The Wmax (physical fitness) changed modestly from 110 to 123 watt in the HIF group, and from 97 to 103 watt in the LIF group (p = 0.3). VAS for pain increased from 53 to 64 mm in the HIF group and from 52 to 54 mm in the LIF group. The large standard deviations around mean change in global assessments, number of tender points, total myalgic score, and psychological distress (by SCL-90) severely influenced the power to detect within- and between-group differences. Analysis limited to those patients who accomplished a high attendance rate (> 67%) showed similar results. CONCLUSION: High intensity physical fitness training compared to low intensity physical fitness training leads to only modest improvements in physical fitness and general well being in patients with FM, and does not positively affect psychological status and general health.

Development of physical fitness standards for Canadian Armed Forces younger personnel.

The purpose of this study was to develop minimum physical fitness standards based on common task criteria for personnel younger than 35 years of age in the Canadian Armed Forces. A random sample of 66 men and 144 women performed the Exercise Prescription (EXPRES) test and five physically demanding tasks that simulated common military tasks. Common cutting scores were selected as the point at which 75% of the total weighted sample passed each task. Since there were significant differences between the sexes in task performance and technique execution, the groups were analyzed separately. Results indicated a range in variance of 14 to 48% between military task performance and physical fitness test score, thus suggesting that fitness measures are a poor predictor of task performance. Because of the low variance observed the passing group of each task was treated as a representative sample of subjects whose fitness profiles were indicative of those able to meet task criteria. The 5th percentile fitness scores of the passing group were proposed as the minimum fitness standard. These conditions resulted in fitness standards that were physically more demanding for women than for men.
