The effect of exercise on anterior knee laxity in female basketball players.
To study the effect of physical activities on the anterior laxity of the knee joint, the anterior knee laxity of female semi-professional basketball players was measured during a typical day. The participants worked in the office in the morning, and practiced in the afternoon, which included a 60 minute warm-up, followed by a 150 minute game style practice. The laxity was measured six times in one day at different activity levels. The anterior knee laxity did not change during sedentary work in the morning, but increased significantly with game style practice. After 1 1/2 hours the increased anterior knee laxity had not recovered completely. However, after five hours it had recovered completely.
