Handgrip strength as determinant of upper body strength/physical fitness: a comparative study among individuals performing gymnastics (ring athletes) and gymnasium (powerlifters)

Abstract

Background: This study was conducted on two different exercising groups, that is, gymnasium (powerlifters) and gymnastics (ring users). Although the type of physical activity is different, but both of the groups require stamina and coordination of central nervous system and skeletal muscles. In the two groups, the muscle strength of the upper body is remarkable and the handgrip has to be effectual for holding rings (gymnastics) and weights (gymnasium). Also, the time for which the grip can be maintained, which determines the endurance of the individual, is vital. Objective: To find the difference in handgrip strength (HGS) and handgrip endurance (HGE) among the two physically active groups. Materials and Methods: This study was conducted on a total of 75 subjects, divided into three groups of 25 each, namely, gymnastics, gymnasium, and control, that is, non-exercising group. Anthropometric hand measurements and skinfold thickness, forearm circumference, and forearm muscle were taken with HGS and HGE. Statistical analysis was then done to draw inference. Result: The study revealed statistically significantly high HGS and HGE in exercising group, in comparison to the control group, also the HGS was maximum in the gymnasium group (p < 0.0001). Moreover, the forearm circumference and the forearm muscle area were maximum (p < 0.0001) and the skin fold thickness was found to be the least in the gymnasium group. The study revealed positive correlation among HGS and HGE with forearm muscle mass. Thus, the study concluded the positive effect of physical activities on HGS and the weight training of the muscles increases their efficiency due to more acquisition of strength and development. Conclusion: In view of the fact that our day-to-day activities, right from household work, official work, to sports, require good HGS, a consistent assessment of handgrip forms an integral part of rehabilitation, not only to assess the strength of muscles involved in gripping but also to apply as a tool in rehabilitating patients with variable levels of hand injuries and in many clinical conditions such as diabetes. Also, in the field of sports, it affects the performance and, therefore, can be implemented as a useful parameter by the coach in their fitness and training program.
