Summary

Frequent sports events causing more injuries in athletes causing decline in their performance. Injuries around knee joint are common. Strength training of hamstring and quadriceps are effective tool in rehabilitation. The multi-speeds and multi-angles strength training plans were used to see the effects on symptoms and performance in athletes.

Detailed description

A total of 69 athletes with knee pain were recruited and randomly divided into two groups. 50 athletes completed the training programs, 25 in each group. Data was also collected from healthy athletes for normative values. International Knee Documentation Committee subjective knee evaluation form was used to report the athlete's knee condition and severity of symptoms including pain. Biodex isokinetic system was used for isokinetic and isometric strength trainings and kinetic data collection. Physical performance of an athlete was assessed by components of fitness through two commonly used tests: Illinois agility run test and vertical jump test. The athletic single leg stability test was used to assess the stability of athletes on Biodex Balance System.

Conditions

• Knee Injuries

Interventions

Type	Name	Description
OTHER	isometric strength training and isokinetic strength training	Isokinetic strength program included strength training at 5 different velocities from slow to fast. Participants were trained on speed of 30°/sec, 90°/sec, 150°/sec, 210°/sec and 270°/sec. Flexion and extension movements were completed with 5 repetitions at each speed. Participants of isometric strength training group performed isometric contractions at 30°, 45° and 60° of knee flexion with five repetitions at each angle for both hamstring and quadriceps.
