OBJECTIVES To test the safety and effects of exercise conditioning on cardiorespiratory fitness, body composition, muscle strength, glucose regulation, and lipid/cholesterol levels. SUBJECTS Ten male adolescents with insulin-dependent diabetes mellitus (IDDM) and 10 adolescent nondiabetic (ND) subjects. DESIGN Pretest, posttest intervention trial with(More)
AIM Extensive research has been undertaken in the area of exercise and hydration. Most work has focused on prehydration. Less is known about different fluid intake patterns during exercise and its effect in thermoregulatory variables in hot environments. This study attempted to determine if ingesting fluid either in a single bolus or intermittently during(More)
Steady state exercise is widely used for psychophysiological studies in which a constant heart rate at a predetermined level is desired. We have developed a microcomputer servo-controlled bicycle ergometer system that can be used for administering steady state exercise. Fourteen healthy male subjects, with a wide range of fitness levels (measured by VO2max)(More)
The purpose of this study was to examine the effect of prolonged exercise on plasma lipid and lipoprotein concentrations and to identify caloric time-points where changes occurred. Eleven active male subjects ran on a treadmill at 70% of maximal fitness (VO2max) and expended 6278.7 kilojoules (Kj) energy (1500 kcal). Blood samples were obtained at the(More)
Exercise training can improve lipid and lipoprotein concentrations and reduce the risk of heart disease. Little information is available concerning aerobic dance training and lipoprotein concentration changes in women. The purpose of this study was to compare the effects of two different methods of step bench training on cardiorespiratory fitness, body(More)
