OBJECTIVE To evaluate the effects of energy restriction with or without aerobic exercise on thigh muscle mass and quality in adults with visceral adiposity. METHODS 75 males and females were randomly assigned to the groups 'diet only' (DO; n = 42) or 'diet plus aerobic exercise' (D/Ex; n = 33) for 12 weeks. The target energy intake in both groups was 25(More)
SUMMARY OBJECTIVE To study the effects of a 12-week continuous aerobic exercise program without energy restriction on intrahepatic fat, indices of liver function (aspartate aminotransferase [AST], alanine aminotransferase [ALT] and γ-glutamyl transpeptidase [γGTP]), plasminogen activator inhibitor-1 (PAI-1) and insulin resistance (HOMA-IR). METHODS(More)
SUMMARY The relationship between minute-by-minute stepping rate under free-living and obesity remains unclear. The purpose of the present investigation was to compare the levels of physical activity (PA) based on the minute-by-minute stepping rate under free-living conditions between normal weight (NW) and overweight and obese (OV) individuals. A total 40(More)
PURPOSE To evaluate the relationships between insulin sensitivity (IS), body fat accumulation, and aerobic capacity in middle- to older-aged Japanese participants with visceral adiposity. PARTICIPANTS AND METHODS Aerobic capacity was measured during an incremental ramp exercise test. Computed tomography was used to measure visceral (VFA) and subcutaneous(More)
SUMMARY AIM This study evaluated the relationships between body fat accumulation, aerobic capacity and insulin resistance (HOMA-IR) in 61 Japanese participants. METHOD The participants were middle-aged to elderly (age: 33-73; BMI: 21.6-38.5). Body fat mass (FM) was evaluated by hydrostatic weighing. Computed tomography was used to evaluate visceral and(More)
