Brief summary: Hamstring injuries are highly prevalent among cricket players, comprising 10% of all injuries in field-based team sports. Eccentric strength deficits and imbalances in muscle strength are linked to a higher risk of such injuries. Our randomized clinical trial aims to assess eccentric hamstring strength using eccentric banded leg curls and eccentric cable leg curl exercises, measured by the Nordbord device. This tool provides accurate measurements of eccentric hamstring strength, power, and endurance, crucial for injury prevention in athletes. Thirty-two male professional cricketers will participate, divided into two groups receiving different exercise plans. Each group will perform 15 reps in 3 sets with rest intervals, four times a week for four months. The Nordbord device will assess hamstring strength before and after the exercise plan. Statistical analysis will be done using SPSS V25, employing descriptive statistics for frequency distribution and inferential statistics such as t-tests to compare outcomes between treatment groups.

Detailed description: The present study aims to assess the effects of eccentric banded leg curls versus eccentric cable leg curls exercise on eccentric knee-flexor strength assessed with an instrumented Nordic hamstring device (Nordbord) after training in Cricket Players.

Eligibility criteria: Inclusion Criteria:

* Participants range in age from 14 to 35 years.
* Only male individuals are eligible for inclusion.
* Eligible participants include professional cricketers at domestic and international levels (U-16, U-19, or above), as well as recent additions to domestic cricket.
* Participants must have either good health or chronic lower extremity injuries impacting hamstring muscle strength.
* Willingness to provide informed consent is a prerequisite for study participation.

Exclusion Criteria:

* Individuals outside the age range of 14 to 35 years are excluded.
* Exclusion criteria include a medical history of neurological or musculoskeletal conditions impacting the lower extremities, such as nerve disorders or severe arthritis.
* Those with lower extremity injuries sustained within the previous two months are ineligible.
* Participants who have undergone lower extremity surgery within the past six months are not eligible.
* Exclusion applies to individuals taking medications that may impact muscle strength or neuromuscular function.
* Individuals who refuse to provide informed consent are not included in the study.
