Effects of aerobic and anaerobic training on stroke volume responses to active stress

The study was proposed to examine the changes on stroke volume responses to active stress with aerobic and anaerobic training among untrained male university students. Forty-five untrained male university students, in the age group of twenty to twenty-five years were selected as participants, and they were segregated into three groups namely: control, aerobic and anaerobic training groups. The duration of experimentation period was restricted to twelve weeks and the frequency of training was thrice a week. The other independent variable confined to this study is aerobic exercise stress testing using Bruce treadmill protocol to evaluate its influence on stroke volume. The data on stroke volume were measured at rest and after exercise conditions from all the three groups, before and after twelve weeks of experimentation. The data thus collected was subjected to three-way factorial ANOVA with repeated measures on last two factors. The findings of the study revealed that the stroke volume at rest and after exercise conditions of aerobic and anaerobic training groups altered significantly for better as a result of respective training, where aerobic training has the upper hand as compared to anaerobic training for its effectiveness on stroke volume.
