Sex: ALL
Minimum age (years): 18
Maximum age (years): 35
Standard ages: ADULT
Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Athletes were randomly assigned into two groups: Isometric (ISOM) and Isokinetic (ISOK). A coin was flipped at start of data collection for the first patient to be assigned odd number and included in isometric group. Later on odd and even numbered patients were included in specific group. Additionally, data was collected from healthy athletes doing their training at Pakistan Sports Board, called healthy control group. Due to ethical constraints knee pain athletes were not included as control subjects
Primary purpose: TREATMENT

Brief 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.

Eligibility criteria: Inclusion Criteria:

* The adult athletes between ages 18 to 35 years.
* Athletes with unilateral knee pain.
* Both male and female.

Exclusion Criteria:

* Athletes with bilateral knee pain and any deformity around knee were excluded from this study.
* Any other joint involvement of lower limb while assessment were also excluded from study.
* Athletes with recent history of surgeries for fractures or ligamentous reconstruction were excluded from this study.
* Patients who were medically unstable.
