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.

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.
