Abstract:

Reliable and valid assessment of hand strength is important for determining the effectiveness of various sports activities when the hands produce the appropriate muscle gripping force, which manifests as hand grip strength (HGS). The force of the handgrip is recognized as a limiting factor in all manipulative activities performed by the cranial part of the body. The current research included a sample of 18 volleyball players VC "Jahorina" East Sarajevo city (Body height = 173 ± 8.77cm; Body weight= 66.04 ± 9.09kg; Body mass index =22,03±2,19 kg/m²), of a member of the Premier League Bosnia and Herzegovina. The aim of the study was to determine the maximum isometric muscle strength of the handgrip depending on the Body height (BH), Body weight (BW) and Body mass index (BMI). Basic statistical parameters, Simple regression analysis and Pearson correlation matrix were applied for data processing. The obtained research results confirmed a statistically significant influence and correlations of all measured characteristics on Hand Grip Strength (p<0.05; p<0.01), except BMI. The results confirmed a statistically significant influence of Body height on HGS (Pearson r Right hand=0.441; R²Right hand=0.294; p=0.047; Pearson r Left hand =0.534; R²Left hand =0.286; p=0.022) and Body weight (Pearson r Right hand=0.573; R²Right hand=0.329; p=0.013; Pearson r Left hand =0.688; R²Left hand =0.475; p=0.002). The data presented in the study have a huge practical application and can be useful in future research on player selection, identification of talents in volleyball and development of training programs. The obtained research results will be used for analytical and diagnostic purposes of volleyball players in order to have a more efficient training and competition process.
