Introduction:
Efficient dynamic balance can improve motor performance and reduce the risk of injuries in athletes. Maintaining optimal balance is crucial for the performance and injury prevention in recreational athletes. The pursuit of optimizing athletic performance and injury prevention hasled to increased interest in eccentric exercise protocols.

Aim of the study:
To investigate an effect of different distinct eccentric exercise protocols on balance among recreational athletes in relation to dominant and non-dominant legs.

Material and methods:
In this experimental study, a total of 42 healthy recreational athletes, both male and female, aged between 18 to 24 years, and within normal body mass index (BMI; 18.5–24.9 kg/m2) were divided into three groups, Group A followed Protocol 1 (n = 14), which consisted of Nordic hamstring exercise (NHE) and Copenhagen adduction exercise (CAE), Group B performed Protocol 2 (n = 14), putting emphasis on NHE, reverse Nordic hamstring exercise (RNHE), and lunges, and Group C (n = 14) which served as a control group. Dynamic balance was measured pre- and post-intervention after four weeks by using lower quarter Y-Balance test (YBTLQ).

Results:
After the four-week period dynamic balance (dominant and non-dominant legs) notably improved in both treatment groups, as compared to the control group. The improvement was significantly greater in Group A and Group B in contrast to Group C.

Conclusions:
This study concludes that engaging in different eccentric exercise protocols targeting lower limbs leads to improved dynamic balance performance following the intervention.
