IMPACT OF HAND GRIP AND SHOULDER MUSCLE STRENGTHENING PROGRAMME ON FUNCTIONAL PERFORMANCE IN ATHLETES

Abstract

Functional performance in athletes particularly those engaged in sports that require upper limb stability, power, precision, and endurance is influenced significantly by the strength and coordination of the hand grip and shoulder musculature. Hand grip strength (HGS) is a widely used measure of upper limb force production and is considered an indicator of overall athletic strength and neuromuscular readiness. Shoulder muscle strength, particularly of the rotator cuff and stabilizers, is essential for controlling upper limb movement during dynamic sporting actions. Despite the recognized importance of both components, there is limited evidence on the combined effect of a structured hand grip and shoulder strengthening programme on sport related functional performance. This study investigated the effects of an 8 week targeted strengthening intervention on hand grip and shoulder muscle strength and its translation to sport specific functional performance in competitive athletes. Twenty eight athletes (15 males, 13 females; aged 18–30 years) participated in a progressive training protocol involving both hand grip and shoulder strengthening exercises. Outcome measures included hand grip dynamometry, isometric shoulder strength assessments, and sport task performance scores (accuracy, stability, and task execution). Post intervention results demonstrated significant improvements in both strength measures and functional performance outcomes. These findings suggest that integrated upper limb strengthening protocols can enhance athletic performance and should be considered in sport training and rehabilitation programmes.
