Injuries and adherence to walk/jog and resistance training programs in the elderly.

To evaluate the effects of 26 wk of aerobic and resistance training on the incidence of injury and program adherence in 70- to 79-yr-old men and women, 57 healthy volunteers (25 males, 32 females) were randomly assigned to a walk/jog (W/J, N = 21), strength (STREN, N = 23), or control (CONT, N = 13) group. Walk/jog training was for 30-45 min, 3 d.wk-1 with intensity equal to 40-70% heart rate max reserve (HRmax reserve) during the first 13 wk, and 75-85% HRmax reserve for weeks 14-26. STREN training consisted of one set (10-12 repetitions) each of 10 variable resistance exercises performed to volitional fatigue. Forty-nine of the original participants completed the training program. Walk/jog training increased VO2max from 22.5 to 27.1 ml.kg-1.min-1 (P less than or equal to 0.05) while STREN and CONT showed no change. STREN improved significantly in chest press and leg extension strength (P less than or equal to 0.05) while W/J and CONT showed no change. Adherence to training was 20/23 (87%) and 17/21 (81%) in STREN and W/J, respectively. One repetition maximum (1-RM) strength testing resulted in 11 injuries in the 57 subjects (19.3%) while STREN training resulted in only two injuries in 23 subjects (8.7%). Walk training during weeks 1-13 resulted in one injury in 21 subjects (4.8%). Eight of 14 subjects (57%) who began jogging intervals at week 14 incurred an injury: two of eight (25%) of the men and all of the women (6 of 6). All W/J training injuries were to the lower extremity.(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of exercise on the kidney of aging mice.

Quantitative light microscopic and ultrastructural kidney changes were studied in young and old mice subjected to moderate exercise. While there was little or no change in the glomeruli of the young animals, the older age-group showed progressive and statistically significant mesangial sclerosis with obliteration of capillary lumina. Electron microscopy also showed electron dense deposits in both the mesangium and subendothelium. Kidney weight in the young mice subjected to exercise was decreased when compared with the controls, while old animals showed a higher kidney weight after 6 weeks of running exercise. Our results of progressive kidney changes in old exercising animals, together with previous studies on myocardial and skeletal muscle showing parallel changes, stress the need for careful clinical studies on the possible damage of these organs in older people who engage in jogging and heavy exercise.

[Fatigue fractures in the area of the hip joint in joggers].

An increased incidence of fatigue fractures of the lower extremities has been observed as a result of the jogging craze. The authors describe a fatigue fracture of the neck of the femur and a fracture dislocation (not described to date) of the hip joint with fracture of the posterior acetabular margin and avulsion of a femoral head fragment.

Left main coronary bypass for aberrant (aortic) intramural left coronary artery.

This report describes the first saphenous vein bypass graft from the aorta to the left main coronary artery for an aberrant left main coronary artery arising from the anterior sinus of Valsalva. A 20-year-old college student had a cardiac arrest and documented ventricular fibrillation while jogging. He was resuscitated. An anomalous left main coronary artery, arising anteriorly from the right coronary sinus, was demonstrated at operation to be within the wall of the aorta. Following aorta--left main coronary artery bypass with the saphenous vein, results of a stress test were normal, and cardiac catheterization revealed the left coronary system to be entirely supplied by the graft.

Echocardiographic and electrocardiographic measures in obese children after an exercise program.

The influence of an exercise training on anthropometric changes and cardiac dimensions was studied in 18 obese children (age 10 to 11 years). Eighteen obese children participated in a jogging program, 5 days/week, for 1 or 2 years and 15 normal weight children (age 10 to 11 years) in the control group participating in their regular physical education class. Anthropometric measurements, echocardiograms and electrocardiograms were obtained before and after the exercise programs. The weight, degree of obesity and resting heart rate had decreased after 1 year of the exercise training. Left ventricular end-diastolic dimension increased after 1 year of the exercise training. Left ventricular wall thickness did not change. The total voltage in SV1 + RV5 decreased after 3 months of the exercise training but returned to pre-training voltage after 1 year of training. There was no change after 2 years of training. In conclusion, 1 year of exercise in obese children decreased resting heart rate and increased left ventricular end-diastolic dimension and left ventricular mass.

[Skin problems in joggers].

Reports on skin problems in joggers are rare in medical literature. Jogger dermatoses are caused by repeated trauma, mechanic overuse, thermic effects, allergic-toxic reactions and infectious processes. Most common are bullosis mechanica, piezogenic papules, hyperkeratosis haemorrhagica and subungual haematomas. Contact allergies and infections such as athlete's foot, pitted keratolysis and pyoderma are well-known complications in joggers. Frostbite and actinic damage, abrasions of the nipples, collisions with vehicles and injuries by buzzards are further possible incidents to be reckoned with occasionally. In most cases, prophylaxis is possible by training adaptation and use of adequate footwear. Jogger dermatoses usually clear after a suitable jogging-free interval.

[Arthrography following sport injuries to the knee joint].

The arthrography is one of the most important diagnostic methods of sport injuries of the knee joint. The examination must give an exact information to the surgeon; a good technique and standard X-rays are an absolute postulate. The submitted examinations are based on 6687 arthrographies during a period of 5 years. The arthrography should not be carried out before the acute symptomatology has ceased, usually after an interval of 2-3 weeks. Most frequently are the meniscus injuries by rotary traumas of the knee-joint. Football as the most popular sport is responsible for more than 50% of the injuries, followed by skiing, handball and jogging.

Effect of alcohol intake on high-density lipoprotein cholesterol levels in runners and inactive men.

Plasma high-density lipoprotein cholesterol (HDLC) level was measured before and after alcohol abstinence and after resumption of a controlled alcohol dose in 16 marathon runners, 15 joggers, and 13 inactive men. A three-week period of abstinence resulted in a significant decrease in HDLC concentration in the inactive men (49.8 to 41.8 mg/dL). Three weeks of alcohol consumption (1,065 mL of beer per day) produced a significant increase in HDLC level to 50.9 mg/dL. No change in HDLC level was found for the marathon group or the joggers during abstinence or three weeks of alcohol intake. The consumption of alcohol in moderation seems to be associated with increased HDLC levels in inactive men but not in men who engage in regular running or jogging.

Energy consumption and its measurement in physical activity.

The low daily energy consumption of the average adult in the developed countries may be increased in certain individuals either because of the occupation or by voluntary activity in leisure. Jogging is one example of this. However, we have little objective information on activity within the population and epidemiologically this is a serious deficiency. There is a need for not only quantitative data on duration of activity but also its level of strenuousness. On the other hand, depending on the purpose of the measurement, it may not often be necessary actually to measure energy expenditure--heart rate measurement or energy values taken from published tables may be adequate. Indeed, energy expenditure or VO2 may not only be unnecessary but even misleading in some cases. When knowledge of energy consumption is required, (for example, in specialized biochemical or in nutritional studies) heart rates will not usually give an accurate enough prediction and oxygen uptake has to be measured. This has to be converted to energy units either by using the RQ or Weir's (1949) formula. Errors of up to +/- 10% may be common here, especially in short-term measurements in exercise. Weir's formula is more likely to lead to larger error and perhaps should be superceded.

Adductor canal outlet syndrome.

On rare occasions, jogging, skiing, and other athletic activities can cause thrombosis of the superficial femoral artery at the outlet of Hunter's canal. We report three cases in which mechanical trauma of the femoral artery in Hunter's canal resulted in intimal tear and a segmentally localized thrombosis. It was confirmed by anatomic dissection that the intrinsic mechanical trauma occurred at the point where the femoral artery crosses the adductor magnus tendon. This tendon has been previously implicated as a cause of atherosclerotic stenosis and thrombosis. An awareness of its possible relationship to acute intimal injury and thrombosis may result in saving limbs that would otherwise be lost.

[Anaphylaxis induced by exertion].

Exercise induced anaphylaxis (EIA) is a relatively new syndrome described in 1980. It is associated with different kinds of exercise, although jogging is the most frequently reported. The clinical manifestations progress from pruritus, erythema and urticaria to some combination of cutaneous angioedema, gastrointestinal and laryngeal symptoms and signs of angioedema and vascular collapse. In the full-blown phase a differential diagnosis must be done with the following syndromes: exercise-induced asthma, idiopathic anaphylaxis, cardiac arrhythmias, carcinoid syndrome. An elevated serum histamine level during experimentally-induced attacks and cutaneous degranulation of mast cells after attacks proved a mast cell participation in the pathogenesis of the syndrome. As predisposing factors, a specific or even aspecific sensitivity to food has been reported and such cases are called "food-dependent EIA". Another precipitating factor includes drug intake; moreover a familial tendency has been reported in some studies. Although the prognosis of this syndrome is not well defined, a reduction of attacks occurs in 45% of patients by means of elimination diets and behavioural changes. Treatment of attacks should include all the manoeuvres efficacious in the management of conventional anaphylactic syndrome, including the epinephrine administration. Prevention of attacks may be achieved by limitation of the exercise program or interruption of the program at the appearance of the first premonitory symptoms. The use of H1 antihistamine-receptor antagonists in maintenance therapy seems to be useful, although no controlled data are available.

[Bilateral intra-patellar tendon rupture in a previously healthy woman].

Bilateral infrapatellar tendon rupture is a relatively rare injury. We describe the case of a 32 year old woman who stumbled and sustained a bilateral infrapatellar tendon rupture while jogging. In our opinion, this represents an unusual mechanism of injury, and we also find it unusual that it was a bilateral injury in an otherwise healthy patient. Diagnosis was confirmed by surgical exploration eight days after admission to hospital. Despite repeated clinical, X-ray and ultrasound examinations, the diagnosis was delayed since we initially did not consider the trauma adequate to cause such an extensive injury. The diagnosis of patella tendon rupture should be based on careful consideration of the history of the injury and thorough clinical examination. X-ray and ultrasound can be of diagnostic help.

Bench stepping and running in women. Changes in fitness and injury status.

BACKGROUND: The purpose of this investigation was to evaluate injury rates and changes in VO2peak in women associated with aerobic exercise (bench stepping and running). METHODS: A pretest post-test repeated measures design was used to evaluate changes in VO2peak after training for 10 weeks, 3 days per week, for 1 hour per session. Injury incidence was monitored by questionnaires throughout the training program. SETTING: All testing and training took place at Auburn University Montgomery, Montgomery, AL, USA. PARTICIPANTS: The subjects were women enrolled in university physical activity courses. The exercise groups consisted of 23 women who performed bench exercise and 15 who performed running-jogging. Eleven subjects served as non-exercising controls. INTERVENTION: The 10-week exercise training program served as the intervention. MEASURES: Subjects were both pre- and post-tested for VO2peak by open circuit calorimetry. Body composition was estimated from a 7-site skinfold equation. A daily injury log was maintained to evaluate injury status. RESULTS: A repeated measures ANOVA found similar significant improvements in VO2peak for both the bench and running groups with no change for the control group. An evaluation of the injuries graded II or higher found 0.29 injuries per 100 hrs for the bench group and 0.66 injuries per 100 hrs for the running group. When all complaints were considered (grade I to grade IV) the rates increased to 2.44 per 100 hrs for the running group and 6.09 per 100 hrs for the bench group. CONCLUSIONS: Aerobic bench exercise produced similar changes in VO2peak compared to running. The results indicated that the primary injury complaints were grade I and related to delayed onset muscle soreness (DOMS). The bench group experienced an greater incidence of grade I complaints while the running group experienced a slightly greater incidence of more serious grade II or higher injuries.

Leisure and occupational physical activity and risk of colorectal adenomatous polyps.

Multiple studies have shown a protective effect for physical activity on the incidence of colorectal cancer, but few have addressed its association with incident adenomas and none have investigated its association with metachronous adenomas. We interviewed 2,001 patients undergoing colonoscopy in 3 New York City practices between 1986-1988. Of these, 298 had a first diagnosis of adenomas, 506 had normal colonoscopies, 197 had metachronous adenomas and 345 had normal colonoscopies with a past history of adenomas. Subjects were queried regarding use of moderate amounts of recreational exercise (swimming, jogging, biking, racket sports and other sports) on a regular basis, and were also asked to estimate their level of physical activity. Occupational physical activity was assessed through a blinded coding of occupational titles. After adjusting for age, years of education, body mass index, total caloric intake, dietary fiber intake, dietary fat intake and years of cigarette smoking, protective effects of borderline significance were observed among males for leisure physical activity for metachronous and incident cases. Occupational physical activity was found to be significantly protective in male incident cases. Men with increased levels of either occupational or leisure activity showed a reduction for incident and metachronous cases. No effects were observed for females. Thus, in this study, both leisure and occupational physical activity were associated with a reduced risk of incident and metachronous adenomas among men but not women.

Toward a multidimensional Health Assessment Questionnaire (MDHAQ): assessment of advanced activities of daily living and psychological status in the patient-friendly health assessment questionnaire format.

OBJECTIVE: To develop components of a multidimensional Health Assessment Questionnaire (MDHAQ) through the addition of new items in the "patient-friendly" HAQ format, including advanced activities of daily living (ADL), designed to overcome "floor effects" of the HAQ and modified HAQ (MHAQ) in which patients may report normal scores although they experience meaningful functional limitations, and psychological items, designed to screen efficiently for psychological distress in routine care. METHODS: The new MDHAQ items, as well as scales for pain, fatigue, helplessness, and global health status on a 2-page questionnaire, were completed by 688 consecutive patients with various rheumatic diseases, including 162 with rheumatoid arthritis (RA), 114 with fibromyalgia, 63 with osteoarthritis, 34 with systemic lupus erythematosus, 20 with vasculitis, 18 with psoriatic arthritis, 16 with scleroderma, and 261 with various other rheumatic diseases, over 2 years at a weekly academic rheumatology clinic. RESULTS: The new MDHAQ items have good test-retest reliability and face validity. MHAQ scores were highest in patients with RA, and scores for other scales were highest in patients with fibromyalgia. On the advanced ADL, 58% of patients reported difficulty with errands, 68% with climbing stairs, 79% with walking two miles, 87% with participating in sports and games, and 94% with running or jogging two miles. On the psychological items, 75% of patients reported difficulty with sleep, 63% with stress, 61% with anxiety, and 57% with depression. Normal MHAQ scores were reported by 23% of patients and normal HAQ scores by 16% of patients who completed these questionnaires, while fewer than 5% had normal scores on the MDHAQ. CONCLUSION: The MDHAQ items overcome in large part the "floor effects" seen on the HAQ and MHAQ, and are useful to screen for problems with sleep, stress, anxiety, and depression in the "patient-friendly" HAQ format. These data support the value of completion of a simple 2-page patient questionnaire by each patient at each visit to a rheumatologist.

Reported frequency of physical activity, fitness, and fatness in Kuwait.

We studied reported frequency of physical activity (PA), body composition, and fitness in Kuwaiti females (n = 84) and males (n = 72), urban office government employees, or students. A sedentary (SED) group reported no or occasional participation in self-directed PA of 30 minutes or more during the week for the last 6 months; group LOF (low frequency) participated in 1-2 sessions/week (walking, jogging, sports such as volleyball, soccer, or gym); group HIF (higher frequency) reported three or more sessions/week. Aerobic fitness was measured using Bruce's treadmill protocol. Body fat and fat-free mass (FFM) were estimated from seven skinfolds and body weight (BW). Grip strength and trunk flexibility were also measured. Maximal O(2) consumption (VO(2)max)/BW was proportional to reported frequency of PA in males and females, indicating reliability of the reported PA frequencies. SED males (%fat > 25), SED and LOF females (%fat > 30) were overweight. In males, LOF PA was associated with lower %fat and higher flexibility than SED, and in females with higher VO(2)max/FFM than SED. LOF females, in contrast to males, were resilient to or exercised at levels insufficient for fat loss but sufficient for aerobic conditioning of the FFM, likely related to the low VO(2)max of females in which PA would have the most effect. HIF PA (>/=3/week) was associated in females with significantly lower %fat and higher flexibility than SED females and no further aerobic conditioning of the FFM, and in males with no further differences in study variables compared with LOF males. Grip strength was higher in males than females but was unrelated to frequency of PA, likely reflecting lack of strength training in the activities of most participants. Thus, low-frequency PA was associated with health benefits both in males (lower %fat) and females (higher VO(2)max/FFM). Probably due to the generally low fitness level of females and, hence, the high aerobic effort (%VO(2)max) required for exercise sufficient to impinge on fat stores, this was only achieved in females participating in higher weekly frequency (>/=3) of PA.

An unusual cause of dizziness in bulimia nervosa: a case report.

OBJECTIVE: The current article describes the case of a 23-year-old female with purging-type bulimia nervosa who was evaluated by her primary care physician for dizziness and lightheadedness. METHODS: After laboratory studies were performed by her primary care physician, the patient was admitted to the hospital because of severe anemia. The patient had been taking nonsteroidal antiinflammatory drugs (NSAIDS) at prescribed doses for shin splints that were secondary to jogging and developed gastric erosion. RESULTS: Endoscopic examination showed that she had diffuse gastritis with linear, streaky ulcerations throughout the body of the stomach. DISCUSSION: Lightheadedness is a common clinical symptom among individuals with eating disorders, but is typically related to dehydration, malnutrition, hypometabolism, and/or combinations of these factors. Clinicians need to consider NSAID use, which may cause erosive gastritis, blood loss, and lightheadedness.

Effects of resistance and endurance exercise on bone mineral status of young women: a randomized exercise intervention trial.

A substantial body of cross-sectional data and a smaller number of intervention trials generally justify optimism that regular physical activity benefits the skeleton. We conducted an 8 month controlled exercise trial in a group of healthy college women (mean age = 19.9 years) who were randomly assigned to a control group or to progressive training in jogging or weight lifting. We measured the following variables: bone mineral density (BMD) of the spine (L2-4) and right proximal femur using dual-energy x-ray absorptiometry, dynamic muscle strength using the 1-RM method, and endurance performance using the 1.5 mile walk/run field test. A total of 31 women completed the 8 month study. For women completing the study, compliance, defined as the percentage of workout sessions attended, was 97% for the runners (range 90-100%) and 92% (range 88-100%) for the weight trainers. Body weight increased by approximately 2 kg in all groups (p less than 0.05). Weight training was associated with significant increases (p less than 0.01) in muscle strength in all muscle groups. Improvement ranged from 10% for the deep back to 54% for the leg. No significant changes in strength scores were observed in the control or running groups. Aerobic performance improved only in the running group (16%, p less than 0.01). Lumbar BMD increased (p less than 0.05) in both runners (1.3 +/- 1.6%) and weight trainers (1.2 +/- 1.8%). These results did not differ from each other but were both significantly greater than results in control subjects, in whom bone mineral did not change.(ABSTRACT TRUNCATED AT 250 WORDS)
