Abstract Twenty-six low fitness subjects were tested for total body reaction time, strength, agility, and explosive power and then retested on these items seven weeks later. During the intervening six-week period, the subjects participated in a vigorous training program consisting of four 30-minute sessions per week. Statistically significant improvements were displayed in all items tested following the training program.
