Twenty-three male Black African and 23 male Caucasian subjects, ascertained as sedentary, participated in this study designed to determine whether there were differences in skeletal muscle histochemical and biochemical characteristics between racial groups. Muscle fiber type proportions (I, IIa, and IIb), fiber areas and activities of several enzyme markers(More)
The anaerobic performance characteristics of 15 Black males of African ancestry (25 +/- 2 yr; mean +/- SD) and 17 White males of French Canadian ancestry (22 +/- 2 yr) were compared. All subjects were sedentary. Morphological characteristics and body composition were similar in both groups. They were tested for maximal force during voluntary isometric(More)
Large interindividual variation in work capacities and powers are often reported in the literature. The variations are attributed to such varied factors as age, sex, exercise training, and heredity, among others. Ethnic/racial origin as a putative causal factor of such variations has also been considered. Studies of subjects from various countries report(More)
The objective of this report was to compare the performance of sedentary individuals, physical education students, and athletes of various disciplines in 10 s and 90 s maximal cycle ergometer tests. The 10 s power was the highest power output in one second from the 10 s test, while capacities were defined as the total work output during the best 10 s trial(More)
Twenty-four male black African (25.5 +/- 3.0, mean +/- s.d., years of age) and 24 male Caucasian (21.5 +/- 3.6) subjects, ascertained as sedentary individuals, participated in this study designed to determine whether there were racial differences in fat distribution and adipose tissue metabolism while controlling the differences in body fat. An adipose(More)
