Summary
Seven weeks of isokinetic training significantly improved knee extension and flexion torque, power, and energy in lacrosse players. These gains were highly correlated, suggesting predictable improvements from such exercise programs.
Area of Science:
- Sports Medicine
- Exercise Physiology
- Biomechanics
Background:
- Isokinetic training is a common method for enhancing athletic performance.
- Understanding the specific effects on knee joint power and torque is crucial for athletes.
Purpose of the Study:
- To evaluate the impact of a 7-week isokinetic training program on knee extension and flexion.
- To analyze changes in peak torque, torque acceleration energy, average power, and total work.
- To determine the relationships between improvements in these isokinetic measures.
Main Methods:
- Seventeen intercollegiate lacrosse players were divided into exercise and control groups.
- The exercise group underwent isokinetic training (3 sets, 25 reps, 270°/sec, 3 days/week for 7 weeks).
- Isokinetic dynamometry (Cybex) assessed performance at 60, 180, and 270°/sec pre- and post-intervention.
Main Results:
- Significant training effects were observed at 270°/sec for knee extension peak torque, torque acceleration energy, and average power.
- Knee flexion torque acceleration energy also showed significant improvement.
- High correlations were found between increases in peak torque, average power, and torque acceleration energy.
Conclusions:
- Isokinetic exercise training can lead to significant improvements in knee extension and flexion strength and power in athletes.
- The observed correlations suggest that improvements in peak torque, average power, and torque acceleration energy are interconnected outcomes of isokinetic training.
- These findings support the use of isokinetic training to enhance athletic performance in healthy athletes.
