Relationship between subcutaneous fatness and leptin in male athletes.

PURPOSE: Circulating leptin is low in trained subjects and closely related to body fat content. However, data are scarce as to whether differences exist in the relationship between different estimates of adiposity, metabolic parameters, and leptin in endurance- and resistance-trained male athletes. We investigated this relationship with special emphasis on subcutaneous fatness and its distribution. METHODS: 20 endurance (ET) and 17 resistance (RT) athletes recruited from different kind of sports were studied. Fat-free mass (FFM) was estimated by means of impedance and fat mass (FM) was calculated. Subcutaneous fat (SAT) and its distribution was measured by means of the optical device Lipometer at 15 body sites (SAT-layers; from 1-neck to 15-calf) on the right side of the body. Fifteen SAT-layers were summed to calculate SAT. Blood samples were obtained for determination for leptin, insulin, and glucose. Insulin resistance was calculated through the fasting insulin resistance index (FIRI; [insulin x glucose/25]). RESULTS: RT-athletes had a greater body mass and body fat content than ET-athletes, but no differences were found for leptin and metabolic parameters. In all athletes, estimates of adiposity were correlated to leptin. However, in ET-athletes FM (P < 0.05), FFM (P < 0.05), and SAT (P < 0.001) but not metabolic parameters were correlated to leptin. In RT-athletes, SAT (P < 0.0001), metabolic parameters (all P < 0.05), but not FM and FFM were in significant relationship with leptin. Stepwise regression revealed SAT as the main determinant for the variation in leptin in all athletes (adj. R(2 )= 0.52, P < 0.0001). CONCLUSION: The results suggest that estimates of adiposity and metabolic parameters are associated with leptin in a sport-specific manner. Whereas leptin might be regulated by overall subcutaneous fatness in athletes, our study does not imply a main influence of fat patterning on leptin in this group of trained subjects.

Sagittal back motion of college football athletes and nonathletes.

STUDY DESIGN: The study was designed as an ex post facto study using volunteers. OBJECTIVES: To compare sagittal back motion of male college athletes with that of nonathletes and to compare data from both groups with normative data. SUMMARY OF BACKGROUND DATA: Few studies have evaluated athletic demands on the spine. Much of the information on athletic demands comes from electromyographic studies, flexibility comparisons, and lift task studies. Although these studies provide a basis for back testing and evaluation, they do not present direct evidence of athletic low back performance. METHODS: Fifteen male college football athletes and 15 male college nonathletes volunteered for testing using the IsoStation B-200 BSCAN 2.0 protocol (Isotechnologies, Inc., Hillsborough, NC). Measures were recorded for range of motion, isometric flexion and extension, and moderate and high dynamic flexion and extension. Data were analyzed using multivariate analysis of variance. RESULTS: The results of Hotelling's multivariate test were significant. Univariate follow-up analysis showed that athletes had significantly better isometric flexion, isometric extension, moderate dynamic flexion, high dynamic flexion, and high dynamic extension. Athletic data were compared with the BSCAN population data at the 50th and 80th percentile. Athletes were significantly better (P < 0.007) for all variables at the 50th percentile and for all dynamic variables at the 80th percentile. CONCLUSIONS: Within the limitations of the study, college football athletes had better sagittal back motion strength and speed as tested with the B-200 than nonathletes. Population data for the B-200 were representative for nonathletes but nonrepresentative for football players.

Screening adolescent athletes for exercise-induced asthma.

OBJECTIVE: To pilot test an exercise-induced asthma (EIA) screening program using a submaximal step-test and pulmonary function test (PFT) to identify athletes with EIA and to determine if a physical examination or self-reported history could be used to predict the existence of EIA. DESIGN: Screening and diagnostic testing using a convenience sample. SETTING: Birmingham, Alabama, during athletic preparticipation examination (PPE). SUBJECTS: Fifty-two African-American, male football players aged 14-18 years being evaluated for participation in scholastic athletics. No athlete refused participation. Four were excluded because of need for further evaluation unrelated to any pulmonary condition. INTERVENTION: Each athlete completed a medical history, allergy history, physical examination, preexercise pulmonary function test (PFT), submaximal step-test, and a series of postexercise PFTs. MAIN OUTCOME MEASURES: Major outcome measurements were changes in forced expiration volume in 1s (FEV1) or peak expiratory flow rate (PEFR) after completing an exercise challenge. RESULTS: Seventeen of 48 athletes had a > or = 15% decrease in PEFR after exercise. Nine of 48 athletes had a > or = 15% decrease in FEV1 after exercise. The only self-reported item that differentiated subjects with normal and abnormal PFTs was a personal history of asthma (p < 0.05). CONCLUSION: Many athletes can be identified as having abnormal PFTs by use of a submaximal step-test as an exercise challenge. Self-reporting questionnaires and PPEs do not appear to be sensitive enough to identify athletes with this condition. If validated by future studies, this protocol could be used for the diagnosis of EIA.

Conceptions of athletic excellence among children and adolescents.

Youth in grades 3, 6, 9, and 12 were interviewed about their beliefs regarding athletic excellence. A set of open-ended questions assessed beliefs about the source of athletic ability and the differences between excellent athletes and others. Respondents also rated excellent athletes on a checklist containing various physical, cognitive, emotional, and interpersonal traits. Younger children were less likely than adolescents to differentiate excellent athletes. All participants, but especially adolescents, attributed greater physical skills to highly competent athletes. All but the third graders thought excellent athletes were different from others in terms of cognitive skills (e.g., attention, concentration), and adolescents believed excellent athletes also differed from others in terms of attitudes (e.g., motivation, determination). Older males were more likely to believe that athletic excellence was due to natural ability, whereas older females were more likely to attribute excellence to early social support and facilitation.

Menstrual dysfunction in Nigerian athletes.

Menstrual function was assessed in 475 Nigerian athletes in different sports and 606 non-athletes. In general, irregular menstrual cycles and oligomenorrhoea or secondary amenorrhoea (O/A) were more common in the athletes (26% and 21%, respectively) than in the non-athletes (18% and 8%, respectively). Menstruation was more regular and normal in the non-athletes (50%) than in the athletes (22%). It was noted that menstrual dysfunction in the athletes was associated with significantly low body fat, body weight, relative weight for height, and the stress of sports activity. In the groups of athletes the ball game players (35%) and distance runners (51%) most commonly experienced O/A, whereas the incidence of dysmenorrhoea and menorrhagia was most prevalent in the swimmers (37%), and sprinters (42%). Menstrual disturbances were relatively more common in athletes who began training before the menarche (43%).

Energy balance in weight stable athletes with and without menstrual disorders.

The energy balance and nutritional adequacy was assessed in a group of runners with irregular menstrual function (IR, n = 10) and in a comparable group of runners with normal menstrual function (R, n = 10). Based on computerized records of 3 days food intake, the mean content of energy and macronutrients were estimated. Excess energy expenditure (EEE) during training hours was estimated using HF monitoring and individual HF/VO2 nomograms. For the rest of a daily 24 h cycle, estimated values for basal metabolic rate (BMR) and sedentary metabolic rate were applied. Daily training-related excess energy expenditure (2.1 +/- 0.3 vs 2.2 +/- 0.4) MJ (Mean +/- SEM) and total energy expenditure (TEE) (11.0 +/- 0.3 vs 11.2 +/- 0.4) MJ in R vs IR were not different in the two groups. Calculated daily energy intake (EI) was, however, significantly lower in IR (9.7 +/- 0.5 MJ) than in R (12.3 +/- 0.7 MJ), (P = 0.007). Calculated EI and TEE were in balance in R athletes. When the same calculations were applied on IR athletes, a moderate but statistically significant negative energy balance was found (-1.5 +/- 0.6 MJ, P = 0.03). The calculated energy deficit was supported by significantly lower levels of free thyroxine in IR athletes, and may indicate an adaptive lower BMR in IR athletes. Mean intakes of carbohydrates (7.0 g/kg in R and 5.7 g/kg in IR) and protein (1.71 g/kg in R and 1.49 g/kg in IR) were close to guidelines. Intakes were not significantly different in the two groups. The most important difference in macronutrient intake was found in dietary fat (1.70 g/kg in R and 1.04 g/kg in IR) that was significantly lower in the IR group than in the R group (P = 0.007). The weight stable IR and R athletes seemed to meet the recommended intake of carbohydrates, protein and fat in their diet fairly well. However, according to the present calculations, a small energy deficit was observed in IR athletes but not in R athletes. Compared with the intake of the R athletes, this energy deficit seems primarily to be related to a lower intake of dietary fat in IR athletes.

Physical fitness profile of elite athletes with intellectual disability.

UNLABELLED: The aim of this study was to investigate the physical fitness profile of high-performance athletes with intellectual disability (ID) in comparison with able-bodied individuals. METHODS: Participants were 231 male and 82 female athletes. All evaluations were done using the EUROFIT physical fitness test. RESULTS: In comparison with population data, both male and female athletes with ID score better for flexibility and upper body muscle endurance, but have similar or lower values for running speed, speed of limb movement, and strength measures. Compared with age-matched physical education students, male athletes with ID score better for running speed and flexibility, and worse for strength. Female athletes with ID score not different from able-bodied individuals for flexibility, running speed, and upper body muscle endurance, but worse for strength measures. Athletes with ID also have poorer cardio respiratory endurance capacity compared with sportive peers without ID. Furthermore, male athletes have a more differentiated profile depending upon their sports discipline, compared with female athletes. CONCLUSION: It can be concluded that high-performance athletes with ID reach physical fitness levels that are equal to or lower than those of able-bodied sportive counterparts. Further research should investigate the importance of reduced muscle strength to be the limiting factor.

The prevalence of disordered eating, menstrual dysfunction, and low bone mineral density among US collegiate athletes.

The purpose of this study was to examine the prevalence of disordered eating (DE), menstrual dysfunction (MD), and low bone mineral density (BMD) among US collegiate athletes (n = 112) representing 7 different sports (diving, swimming, x-country, track, tennis, field hockey, and softball) and determine differences in prevalence existed between athletes participating in lean-build (LB) and non-lean build (NLB) sports. DE and MD were assessed by a health, weight, dieting, and menstrual history questionnaire. Spinal BMD was determined via dual energy x-ray absorptiometry. Twenty-eight athletes met the criteria for DE, twenty-nine for MD, and two athletes had low BMDs (using a Z score below -2.0). Ten athletes met the criteria for two disorders (one with disordered eating and low BMD and nine with disordered eating and menstrual dysfunction), while only one athlete met the criteria for all three disorders. Using a Z score below -1.0, two additional athletes met the criteria for all three disorders and three more athletes met the criteria for a combination of two disorders. With the exception of MD, which was significantly more prevalent among LB vs. NLB sports (P = 0.053), there were no differences between the groups in the prevalence of individual disorders or combinations of disorders. These data indicate that the combined prevalence of DE, MD, and low BMD among collegiate athletes is small; however, a significant number suffer from individual disorders of the Triad.

Stress fractures of the femoral shaft in athletes: a new treatment algorithm.

BACKGROUND: Femoral shaft stress fractures in athletes are not common but pose a great diagnostic challenge to clinicians. Because of few clinical signs, diagnosis and treatment are often delayed. Furthermore, if not treated correctly, these fractures are well known for complications and difficulties. OBJECTIVE: To develop a well structured and reproducible treatment algorithm for athletes with femoral shaft stress fractures. METHODS: The proposed algorithm is carried out in four phases, each lasting three weeks, and the move to the next phase is based on the result of the tests carried out at the end of the previous phase. Over nine years, we treated seven top level athletes, aged 17-21. In all athletes, diagnosis was based on physical examination, plain radiographs, and bone scan. RESULTS: As a result of the treatment method, all the athletes were fully engaged in athletic activity 12-18 weeks after the beginning of treatment. After completion of the treatment, the athletes were followed up for 48-96 months. During the follow up, there was no recurrence of discomfort or pain, and all the athletes eventually returned to competition level. CONCLUSION: These results and data available from the literature suggest that the algorithm is the optimal treatment protocol for femoral shaft stress fractures in athletes, avoiding the common complications and difficulties.

Echocardiographic characteristics of male athletes of different age.

Two dimensionally guided M mode and Doppler echocardiographic data for 578 male subjects (106 non-athletic and 472 athletes) were analysed from two aspects: (a) in the young adult category (19--30 years of age), competitors in different groups of sports were studied; (b) in the different age groups (children, 10--14 years; adolescent juniors, 15--18 years; young adults, 19--30 years; adults, 31--44 years; older adults 45--60 years), data for athletes and non-athletes were compared. Morphological variables were related to body size by indices in which the exponents of the numerator and denominator were matched. Morphological signs of athletic heart were most consistently evident in the left ventricular muscle mass: in the young adult group, the highest values were seen in the endurance athletes, followed by the ball game players, sprinters/jumpers, and power athletes. A thicker muscular wall was the main reason for this hypertrophy. Internal diameter was only increased in the endurance athletes, and this increase was more evident in the younger groups. The E/A quotient (ratio of peak velocity during early and late diastole) indicated more effective diastolic function in the endurance athletes. The values for E/A quotient also suggested that regular physical activity at an older age may protect against age dependent impairment of diastolic function.

Reduction in left ventricular wall thickness after deconditioning in highly trained Olympic athletes.

BACKGROUND: Clinical distinction between athlete's heart and hypertrophic cardiomyopathy in a trained athlete is often difficult. In an effort to identify variables that may aid in this differential diagnosis, the effects of deconditioning on left ventricular wall thickness were assessed in six highly trained elite athletes who had competed in rowing or canoeing at the 1988 Seoul Olympic Games. Each of these athletes showed substantial ventricular septal thickening associated with training (13-15 mm) which resembled that of hypertrophic cardiomyopathy. METHODS: The athletes voluntarily reduced their training substantially for 6-34 weeks (mean 13) after the Olympic competition. Echocardiography was performed at peak training and also after deconditioning, and cardiac dimensions were assessed blindly. RESULTS: Maximum ventricular septal thickness was 13.8 (0.9) mm in the trained state and 10.5 (0.5) in the deconditioned state (p < 0.005) (change 15-33%). CONCLUSIONS: The finding that deconditioning may be associated with a considerable reduction in ventricular septal thickness in elite athletes over short periods strongly suggests that these athletes had a physiological form of left ventricular hypertrophy induced by training. Such a reduction in wall thickness with deconditioning may help to distinguish between the physiological hypertrophy of athlete's heart and primary pathological hypertrophy (for example, hypertrophic cardiomyopathy) in selected athletes with increased left ventricular wall thickness.

Association between type of training and risk of asthma in elite athletes.

BACKGROUND: Intensive endurance training has been associated with a high prevalence of symptoms compatible with asthma in elite athletes. It is not known, however, whether there is an association between the type of training for competitive events and the risk of asthma in highly trained athletes. METHODS: Two hundred and thirteen track and field athletes, mostly from Finnish national teams, and 124 controls of the same age completed a respiratory symptom questionnaire. Positive answers to physician diagnosed asthma were confirmed by personal interviews. The athletes were divided into two groups depending on whether they were speed and power athletes (n = 106) or long distance runners (n = 107). RESULTS: According to a logistic regression model the prevalence of physician diagnosed asthma was not associated with age, sex, or a family history of asthma. Long distance runners (OR 6.7; 95% CI 2.1 to 22.1) and speed and power athletes (OR 3.2; 95% CI 0.90 to 11.4) had a higher prevalence of physician diagnosed asthma than control subjects. Physician diagnosed asthma was found in 18 of 107 long distance runners (17%), in nine of 106 speed and power athletes (8%; p = 0.07 (chi 2 test)), and in four of 124 controls (3%; p < 0.0004 (chi 2 test for trend)). CONCLUSIONS: The prevalence of physician diagnosed asthma is high in elite athletes and an association with the competitive event is suggested with long distance runners having a greater risk of developing asthma than speed and power athletes. This may be due to prolonged hyperventilation and increased exposure to inhalant allergens and irritants during endurance training and competition.

A hemodynamic comparison of young and older endurance athletes during exercise.

This study assessed the hemodynamic responses to exercise of master athletes (56 +/- 5 yr of age) who placed in the top 10% of their age groups in local 10-km competitive events, competitive young runners (26 +/- 3 yr), young runners matched in training and performance to the master athletes (25 +/- 3 yr), and healthy older sedentary subjects (58 +/- 5 yr). The maximal O2 consumption (VO2max) of the master athletes was 9 and 19% lower than that of the matched young and competitive young runners, respectively. When compared at the same relative submaximal work rates, these three groups had similar stroke volumes and arteriovenous O2 (aVO2) differences, though the master athletes had lower VO2, cardiac output, and heart rate, and higher vascular resistance. The older sedentary group had a lower stroke volume, aVO2 difference, and higher vascular resistance than the master athletes. Maximal stroke volume and estimated aVO2 difference were the same in the three groups of athletes; the lower maximal heart rate of the master athletes appears to account for their lower VO2max. The older sedentary subjects' VO2max was 47% lower than that of the master athletes; this difference was almost equally the result of a lower stroke volume and a lower a-VO2 difference. Thus these older athletes did not exhibit the decline in maximum stroke volume and aVO2 difference that occurs with aging in sedentary individuals; they also appear to have retained a greater peripheral vasodilatory response than their sedentary peers.

Size and blood flow of central and peripheral arteries in highly trained able-bodied and disabled athletes.

In a cross-sectional study, central and peripheral arteries were investigated noninvasively in high-performance athletes and in untrained subjects. The diastolic inner vessel diameter (D) of the thoracic and abdominal aorta, the subclavian artery (Sub), and common femoral artery (Fem) were determined by duplex sonography in 18 able-bodied professional tennis players, 34 able-bodied elite road cyclist athletes, 26 athletes with paraplegia, 17 below-knee amputated athletes, and 30 able-bodied, untrained subjects. The vessel cross-sectional areas (CSA) were set in relation to body surface area (BSA), and the cross-section index (CS-index = CSA/BSA) was calculated. Volumetric blood flow was determined in Sub and Fem via a pulsed-wave Doppler system and was set in relation to heart rate to calculate the stroke flow. A significantly increased D of Sub was found in the racket arm of able-bodied tennis players compared with the opposite arm (19%). Fem of able-bodied road cyclist athletes and of the intact limb in below-knee amputated athletes showed similar increases. D of Fem was lower in athletes with paraplegia (37%) and in below-knee amputated athletes proximal to the lesion (21%) compared with able-bodied, untrained subjects; CS-indexes were reduced 57 and 31%, respectively. Athletes with paraplegia demonstrated a larger D (19%) and a larger CS-index in Sub (54%) than able-bodied, untrained subjects. No significant differences in D and CS-indexes of the thoracic and abdominal aorta were found between any of the groups. The changes measured in Sub and Fem were associated with corresponding alterations in blood flow and stroke flow in all groups. The study suggests that the size and blood flow volume of the proximal limb arteries are adjusted to the metabolic needs of the corresponding extremity musculature and underscore the impact of exercise training or disuse on the structure and the function of the arterial system.

Effects of angiotensin-converting enzyme polymorphism on aortic elastic parameters in athletes.

BACKGROUND: Physiologic adaptations in an athlete's heart include increased left and right ventricular chamber size, left ventricular wall thickness and mass. Angiotensin-converting enzyme (ACE) is a key enzyme in angiotensin II production causing cardiac hypertrophy. The cloning of the ACE gene has made it possible to identify a deletion (D)-insertion (I) polymorphism that appears to affect the level of serum ACE activity. Therefore, the ACE genes, which have been shown to be polymorphic, could be candidate genes for large-artery stiffness. METHODS: 56 endurance athletes and 46 sedentary subjects were included in this study, and they underwent both complete echocardiographic examination, and analysis of ACE insertion (I) and deletion (D) allele frequencies in peripheral blood. The aortic diameter was recorded by M-mode echocardiography at a level 3 cm above the aortic valve. Aortic systolic diameter was measured at the time of full opening of the aortic valve, and diastolic diameter was measured at the peak of QRS. Aortic strain, stiffness index and distensibility were calculated. RESULTS: Left ventricular mass index and left ventricular ejection fraction were significantly higher in athletes than controls (p < 0.001). The aortic distensibility index and strain were significantly greater in athletes compared with controls (respectively: 5.8 +/- 2.7 vs. 4.7 +/- 1.8 cm(-2) dyn(-1) 10(-6), p = 0.017; 12.3 +/- 2.4 vs. 9.3 +/- 3.1, p < 0.001). The aortic stiffness index was significantly lower in athletes than in controls (4.8 +/- 1.9 vs. 6.1 +/- 2.1, p < 0.001). The aortic distensibility index and strain were statistically different in ACE DD vs. DI groups and DD vs. II groups of athletes. The aortic stiffness index was statistically different in ACE DD vs. II groups of athletes. Aortic parameters were similar according to ACE genotypes in controls. CONCLUSION: The results of this study indicate that aortic distensibility was increased by prolonged training in endurance athletes, particularly in those with the ACE II genotype. This effect represents an extracardiac adaptation to chronic prolonged training in athletes.

Clinical significance of abnormal electrocardiographic patterns in trained athletes.

BACKGROUND-The prevalence, clinical significance, and determinants of abnormal ECG patterns in trained athletes remain largely unresolved. METHODS AND RESULTS-We compared ECG patterns with cardiac morphology (as assessed by echocardiography) in 1005 consecutive athletes (aged 24+/-6 years; 75% male) who were participating in 38 sporting disciplines. ECG patterns were distinctly abnormal in 145 athletes (14%), mildly abnormal in 257 (26%), and normal or with minor alterations in 603 (60%). Structural cardiovascular abnormalities were identified in only 53 athletes (5%). Larger cardiac dimensions were associated with abnormal ECG patterns: left ventricular end-diastolic cavity dimensions were 56. 0+/-5.6, 55.4+/-5.7, and 53.7+/-5.7 mm (P<0.001) and maximum wall thicknesses were 10.1+/-1.4, 9.8+/-1.3, and 9.3+/-1.4 mm (P<0.001) in distinctly abnormal, mildly abnormal, and normal ECGs, respectively. Abnormal ECGs were also most associated with male sex, younger age (<20 years), and endurance sports (cycling, rowing/canoeing, and cross-country skiing). A subset of athletes (5% of the 1005) showed particularly abnormal or bizarre ECG patterns, but no evidence of structural cardiovascular abnormalities or an increase in cardiac dimensions. CONCLUSIONS-Most athletes (60%) in this large cohort had ECGs that were completely normal or showed only minor alterations. A variety of abnormal ECG patterns occurred in 40%; this was usually indicative of physiological cardiac remodeling. A small but important subgroup of athletes without cardiac morphological changes showed striking ECG abnormalities that suggested cardiovascular disease; however, these changes were likely an innocent consequence of long-term, intense athletic training and, therefore, another component of athlete heart syndrome. Such false-positive ECGs represent a potential limitation to routine ECG testing as part of preparticipation screening.

Improving athletes' perspectives of sport psychology consultation: a controlled evaluation of two interview methods.

Although investigations have consistently demonstrated the effectiveness of sport psychology interventions, these methods have been underutilized by athletes. In this study, 124 athletes completed the athletes' Attitudes Toward Seeking Sport Psychology Consultation Questionnaire (ATSSPCQ) and were subsequently randomly assigned to receive one of the two semistructured interview formats. One interview focused on discussing the athlete's experiences in sports, and the other focused on delineating sport psychology and its potential benefits to the athlete. Upon being interviewed, athletes were readministered the ATSSPCQ. Discussing sport psychology and its personal benefits was more effective in enhancing athletes' perception of need for sport psychology than discussing sport experiences. However, neither interview format enhanced athletes' perceptions of openness to discuss personal issues with a sport psychology consultant and tolerance of stigma associated with sport psychology consultation. Indeed, participants who received the discussion of sports intervention reported a significant decrease in personal openness to discuss personal issues relevant to sports psychology from pre- to postintervention. Intervention effects were similar for male and female athletes. Study implications and future directions are discussed in light of these results.

Dietary habits of athletes in Bahrain.

This study describes the dietary habits of athletes involved in four common sports in Bahrain (football, handball, volleyball and basketball). A sample of 304 athletes was obtained from 14 first class clubs. It was found that 28% of athletes skipped breakfast, and only 39% consumed breakfast daily. Foods eaten before competition were similar to those consumed by other family members, indicating that athletes did not eat any specific diet before events. There were some differences in meal patterns among athletes of various sports. In general, athletes allowed enough time between a meal and competition (2.8-3.1 hours). About half of them consumed water only at restbreak, while the rest consumed fruit drinks, tea and oranges in addition to water. Some (3%) did not consume any fluid. A small proportion of the athletes (4%) used vitamins and protein supplements. Mass media (53.6%) and coaches (20.1%) were the primary sources of nutrition information for athletes. It is suggested that information on nutrition and physical performance should be introduced in all educational programmes for both athletes and coaches.
