About

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.

Full 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.

50 participants in 3 patient groups

Isometric strength training group

Active Comparator group

Description:

Knee pain athletes were assessed by The International Knee Documentation Committee (IKDC) 2000 Subjective Knee evaluation form and were assigned into ISOM group. ISOM group participants were involved in isometric strengthTraining at angle of 30°,45°,60° of knee flexion for 5 maximum contraction for both hamstring and quadriceps. 10 sessions were given on alternate day basis by using Biodex Isokinetic system.

Treatment:

Other: isometric strength training and isokinetic strength training

Isokinetic strength training group

Active Comparator group

Description:

Knee pain athletes were assessed by The International Knee Documentation Committee (IKDC) 2000 Subjective Knee evaluation form and were assigned into ISOK group isokinetic training group randomly. ISOk group participants were involved in Training at speed of 30 deg/sec, 90deg/sec, 150/deg/sec 210deg/sec, 270deg/sec 5 repetition for both hamstring and quadriceps. 10 sessions were given on alternate day basis by using Biodex Isokinetic system.

Treatment:

Other: isometric strength training and isokinetic strength training

Healthy control group

No Intervention group

Description:

Data for outcome parameters including Peak torque average peak torque average power agonist antagonist ratio by using biodex isokinetic system for both by isometric contraction method and isokinetic method. For performance test were recorded for healthy control of same age group to compare the training effect with healthy control values.
