BACKGROUND Regular exercise increases exercise self-efficacy and health-related quality of life (HRQOL); however, the mechanisms are unknown. We examined the associations of exercise adherence and physiological improvements with changes in exercise self-efficacy and HRQOL. METHODS Middle-aged adults (N = 202) were randomized to 12 months aerobic exercise (360 minutes/week) or control. Weight,...

Background—Practising the martial art of taekwon-do (TKD) has been proposed to have beneficial eVects on cardiovascular fitness as well as general physical ability. Furthermore, TKD masters and participants have promoted TKD as a total fitness programme. Research studies substantiating this, however, seem to be lacking, perhaps because TKD is recognised more as a method of self defence than a f...

the aim of this study was to determine the effect of 6 weeks of aerobic training and l-carnitine supplement on body fat percent and serum lipid profiles in active men. the method used was semi-experimental. eighteen active men were selected voluntarily and randomly divided into two groups of experimental (nine individuals with the average age: 44.4+8 years, weight: 8.2+16.6 kg, height: 173+6 cm...

BACKGROUND Fisherwomen contribute significantly to the coastal economy of Eastern India; however, data about their physical fitness and weight status are scant. OBJECTIVES The present cross-sectional study was designed to investigate cardiorespiratory fitness and weight status of fisherwomen, which may be influenced by their occupational workload, using morphometric and anthropometric measure...

The relationship between insulin resistance (HOMA-IR), percent body fat, and aerobic fitness (VO2max per unit fat free mass; mL/kgFFM/min) was examined in 1,710 children. Percent body fat was estimated from sum of skinfolds, and VO2max was estimated from submaximal cycle ergometer tests. Overnight fasting blood samples were obtained. VO2max (mL/kgFFM/min) and percent body fat were correlated wi...

The effect of regular aerobic exercise on body fat is negligible; however, other forms of exercise may have a greater impact on body composition. For example, emerging research examining high-intensity intermittent exercise (HIIE) indicates that it may be more effective at reducing subcutaneous and abdominal body fat than other types of exercise. The mechanisms underlying the fat reduction indu...

Methods Twenty-five well-trained recreational athletes (mean ± SD age = 21 ± 2 yrs; stature = 172 ± 9 cm; body mass = 66 ± 12 kg, VO2max = 48 ± 9 ml·kg-1·min-1, percent body fat = 19 ± 7%) were assigned to either the active supplement (n = 12) or placebo (PL, n = 11) group. The active supplement (Game Time®, GT, Corr-Jensen Laboratories Inc., Aurora, CO) was 18 g of powder, 40 kcals, and consis...

OBJECTIVES The United States Air Force (USAF) Combat Controller (CCT) training pipeline is extremely arduous and historically has an attrition rate of 70-80%. The primary objective of this study was to identify the physiological, psychological, or demographical characteristics associated with successful progression through the CCT pipeline program. METHODS A battery of physiological measureme...

Background. Archery is a sport that demands a high level of fitness due to its long hours of training and competitive nature. Thus, archers need to have high fatigue tolerance and body figure to perform successfully. Objectives. This study aims to compare and correlate the anthropometric and physical fitness variables on archery shooting performance. Methods. Participants were youth archers o...
