Abstract
The effects of two 4-week training programs on knee flexor and extensor strength were measured isokinetically (angular velocity 30°, 180°/s) and isometrically in division IV soccer players. Group A followed a team training program and group C an individual weight training program. Group C served as controls.
Muscle strength was not increased by soccer training alone, but was increased by the individual training program, which resulted in significantly better knee extensor strength than did trie team training program.
