A 4-week supervised training program (3 hrs/week) was administered to a group of young people (N = 139,94 M, 45 F) to improve components of ballistic, discontinuous, skill based athletic performance. Changes in 5 criterion variables over time and as a function of training were monitored to determine if training occurred. Results indicate that when the entire cohort was considered, significant (p < 0.05) improvements from pretraining values were observed in the 20-yd dash, hexagon drill, spider drill, sideways shuffle, and vertical jump height. When 2 subgroups were formed from the cohort as a function of gender, each group independently achieved significant improvements in each criterion variable. Correlation analyses indicate that the slowest boys (highest pretraining times) had the greatest improvement in 20-yd dash, hexagon drill, and sideways shuffle. The slowest girls had the greatest improvements in all running drills: 20-yd dash, hexagon drill, spider drill, and sideways shuffle; the girls with the lowest pretraining vertical jump had the greatest jump improvements. Thus the relatively short training program improved performance in 5 drills used to measure acceleration, speed, coordination, dynamic balance, agility, lateral movement, and explosive power, and the gains were not gender-specific.
