Hypothalamic-Pituitary-Adrenal Responses to Short Duration High Intensity Cycle Exercise ( Book )
1 edition published in 1988 in English and held by 2 WorldCat member libraries worldwide
Beta-endorphin (B-EP), adrenocorticotropin (ACTH) and cortisol plasma concentrations were examined before and after maximal exercise at four intensities (36, 55, 73 and 100% of maximal leg power (MLP) utilizing a computerized cycle ergometer. All intensities were greater than those eliciting peak oxygen uptake for the individual subjects. Blood samples were collected at rest, immediately following exercise (IP) and at 5 and 15 min post-exercise. Significant (p <0.05) increases were observed at 36% MLP for B-EP and ACTH at IP, 5 and 15 min post-exercise. Plasma cortisol increased at 36% MLP at 15 min post exercise. Blood lactate significantly increased at all post-exercise collection points for exercise intensities of 36, 55 and 73% MLP and at 5 min post exercise for 100% MLP. B-EP concentrations at 36% MLP were significantly correlated (r=0.75) with capillary density (mm-2) and cortisol concentrations at 36% MLP were significantly correlated (r=0.89) with % type II muscle fibers. No other significant relationships were observed. Keywords: Beta endorphin, Adrenocorticotrophin, Cortisol, Blood lactate, Skeletal muscle fiber morphology, Anaerobic exercise
Exercise Endurance Time as a Function of Percent Maximal Power Production ( )
1 edition published in 1986 in English and held by 1 WorldCat member library worldwide
To develop and statistically validate a mathematical model of the relationship between endurance time (T) and power production, 15 male subjects were first tested for maximal power on an instrumented cycle ergometer at 60 RPM. On subsequent days they were tested for T at various percentages of maximal power. Curves of T as a function of percent maximal power were curvilinear, and could be made to overlap among subjects by individual abscissa scaling, which resulted in the appearance of horizontal stretching or compression of the curves. The degree of stretching-compression was defined by a statistically obtained scaling factor (F) which served to quantify each subject's endurance ability at fractions of maximal power. F was used to transform percent of maximal power to a scaled power variable (P sub sc). A curve of the form T = a times (P sub sc) to the bth power was developed on 10 of the subjects and validated on the remaining five. Correlation between predicted and actual T was 0.976 for the fitting group and 0.980 for the validation group. A maximal power test and a single endurance test at 40-50% of maximal power were found to establish individual endurance-power curves fairly well, with a correlation of 0.828 between actual and predicted T. The combination of F and maximal power for a given physical activity provide a useful profile of an individual's ability to perform at constant exercise intensity

Factors in Maximal Power Production and in Exercise Endurance Relative to Maximal Power ( )
1 edition published in 1988 in English and held by 1 WorldCat member library worldwide
The relationship of muscle fiber type and mass to maximal power production and the maintenance of power (endurance time to exhaustion) at 36, 55, and 73% of maximal power was investigated in 18 untrained but physically active male subjects. Power output was determined at constant velocity (60 RPM) on a high intensity cycle ergometer instrumented with force transducers and interfaced with a computer. Fat free mass was determined by hydro-static weighing, fat free thigh volume by water displacement and skinfold measurement, and percentage and area of type II fibers from biopsies of the vastus lateralis. Maximal power averaged 771 + or - 149 W with a range of 527-1125 W. No significant correlations were found among percentage of type II fibers, relative area of type II fibers, or fat free thigh volume and maximal power or endurance times to exhaustion at any percentage of maximal power. Weak but significant relationships were found for fat free mass with both maximal power (r=0.57) and endurance time at 73% of maximal power (r=0.47). These results show maximal power to be more dependent on factors related to body size than muscle fibers characteristics.
