EFFECT OF STATIC AND DYNAMIC STRETCHING ON KNEE MUSCLE STRENGTH IN TRAINED PLAYERS
Antremanlı Sporcularda Statik ve Dinamik Germe Egzersizlerinin Diz Kas Gücü Üzerine Etkisi
Abstract
Objective: The study examined the effects of two different stretching exercises on knee muscle strength in basketball players in order to determine the most appropriate pre-competition protocols for basketball conditioning.
Method: Thirty-two basketball players (mean age 22.75 ± 2.73 years old, weight 87.47 ± 10.99 kg, height 188.85 ± 7.35 cm, BMI 24.46 ± 1.89) participated in this study. They performed two different stretching protocols according to basketball training experience in randomly assigned order: randomised in consecutive manner according to admission order, well-trained basketball players (training frequency= 5 days/week; Groups I and II), less-trained basketball players (1 day/week; Groups III and IV). Basketball players in Groups I and III were exposed to isokinetic tests—one each after dynamic stretching and, 1 week later, after static stretching. In Groups II and IV, similar evaluations were made after static stretching and, 1 week later, after dynamic stretching. 5 days/week were included in the well-trained group. The less-trained group consisted of basketball players who trained 1 day/week.
Results: In less-trained basketball players, static stretching resulted in higher extensor muscular strength and endurance values, whereas dynamic stretching increased knee flexor strength and endurance.
Conclusions: Our results suggest that before competitions, stretching exercises should be chosen depending on the conditioning of the basketball player (well-trained, less-trained). Including both static and dynamic stretching into the “stretching” concept seems effective.
