Official title: Effects of Eccentric Banded Leg Curls Versus Eccentric Cable Leg Curls Exercises on Eccentric Knee-flexor Strength, Power and Endurance in Cricket Players

Status Not yet recruiting

Clinical Trial 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.

Clinical Trial 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.

A study conducted since 2021 aimed to explore the impact of fatigue on the peak eccentric strength of the hamstring muscle group. Twenty-two professional football players, predominantly right-leg dominant and without ongoing injuries, participated. Using the Nordbord device, their hamstring eccentric strength was measured before and after a 90-minute soccer match. Results revealed a significant decline in eccentric strength post-match compared to pre-match, while the imbalance in strength between dominant and non-dominant limbs remained consistent.

Since 2022, a randomized controlled trial assessed the efficacy of an eccentric-biased home exercise program on hamstring strength. Fifteen healthy adults engaged in a four-week program including various exercises. Participants demonstrated increased peak isokinetic torque in the dominant limb and peak isometric torque in the non-dominant limb. However, some participants showed non-compliance with certain exercises.

Another study investigated the effects of lower-limb training with additional Nordic hamstring exercises (NHE) or sprinting on hamstring strain injury (HSI) risk factors and athletic performance. Thirty-eight collegiate athletes were randomly assigned to different groups and underwent standardized lower-limb training twice a week for seven weeks. Significant increases in muscle architecture and eccentric peak force were observed across all groups. Sprint and NHE training groups showed improvements in sprint times.

Limited literature exists on the use of eccentric Nordic devices (Nordbord) among cricket players. Previous studies have primarily focused on other athletes, utilizing various hamstring eccentric exercises. This study uniquely incorporates eccentric cable leg curls and eccentric banded leg curls for cricket players. ;
