Effects of training regimen (intensity, duration, frequency and period) on aerobic capacity in adult men and women

Abstract

The purpose of the present short review was to evaluate the relationship between the percent increase in Vo_2max (% Vo_2max) and intensity, duration, frequency, period of training, the initial fitness level (Vo_2max) and age, as a reexamination of various studies on different populations with different protocols regarding endurance training. Close connection was recognized between the magnitude of improving Vo_2max and the duration and period of training in male and the frequency of training in female. More important factors found to improve Vo_2max were initial fitness levels of the individuals in male and female, i. e., one with lower initial scores showed a greater percent increase. Furthermore, the present study had shown that minimum training thresholds for improving Vo_2max were 40-50% Vo_2max for intensity, 20-30min/session for duration, 2-3 sessions/wk for frequency and several weeks for period of training.
