Relationship between handgrip strength and vertical jump performance in Olympic female volleyball players 2025 http://ezaposleni.singidunum.ac.rs/rest/sciNaucniRezultati/oai/record/2/11796 https://journals.lww.com/nsca-jscr/abstract/2025/07000/relationship_between_handgrip_strength_and.11.aspx Cabarkapa, D.V. Cabarkapa, D. Bankovic, V. The purpose of this study was to examine the relationship between maximal upper-body strength assessed using a handgrip dynamometer and lower-body strength and power-producing capabilities assessed through countermovement vertical jump (CMJ). Sixteen female Olympic volleyball players volunteered to participate in the present investigation. After completing the warm-up routine, all athletes performed 3 CMJs with hands on hips (i.e., no arm swing) while standing on a dual uniaxial force plate system sampling at 1,000 Hz. The following metrics were derived from the force plate system: eccentric peak and mean force, concentric peak and mean force, and vertical jump height (i.e., impulse-momentum calculation). After the completion of the CMJ testing protocol, the handgrip strength was assessed using a digital dynamometer. Pearson product-moment correlation coefficients were used to measure the strength of linear regressions (p < 0.05). The results revealed moderate to strong associations between handgrip strength and CMJ performance (r = 0.415-0.696). Specifically, the dominant handgrip strength revealed a statistically significant relationship with 8 of 9 force-time metrics of interest (e.g., eccentric peak force, concentric mean power, and jump height), while the nondominant hand demonstrated a positive association with only 5 of 9 CMJ performance metrics. These results suggest that within this specific cohort of athletes, the strength of the dominant hand might be a better predictor of the overall CMJ performance, including both eccentric and concentric force and power-producing capabilities, as some of the foundational physical attributes that volleyball athletes need to possess. article 10.1519/JSC.0000000000005165 39 7 809 814 1064-8011 JOURNAL OF STRENGTH AND CONDITIONING RESEARCH
