Handgrip strength as a predictor of physical fitness and wellbeing in amateur padel players

Purpose: This study aimed to investigate the relationship between handgrip strength (HGS) and physical fitness performance in amateur padel players, while also examining the association between padel practice and health-related quality of life. Methods: A cross-sectional study was conducted with 87 amateur padel players (45 males, 42 females; mean age 38.7 ± 9.3 years). Participants underwent assessments for HGS using a Jamar Plus dynamometer, physical fitness tests (agility T-test, countermovement jump, 20 m sprint, Yo-Yo Intermittent Recovery Test Level 1), body composition analysis via bioelectrical impedance (BIA Akern), and completed the SF-36 questionnaire for health-related quality of life. Correlation and regression analyses were performed to evaluate relationships between variables, controlling for age, sex, BMI, and training volume. Results: HGS showed moderate-to-strong correlations with all physical fitness parameters (r = 0.57 to 0.72, p<0.001), with the strongest association observed for countermovement jump height (r = 0.72). Phase angle from BIA was significantly correlated with HGS (r = 0.68, p<0.001). Regression analyses confirmed HGS as an independent predictor of physical fitness performance (b = 0.54, p\0.001). Padel practice volume was positively associated with both physical (r = 0.47) and mental (r = 0.39) component summary scores of the SF-36 (p<0.001). Conclusions: HGS is a valid and practical indicator of overall physical fitness in amateur padel players, with strong associations to agility, power, and endurance. Regular padel participation is linked to improved health-related quality of life, highlighting its potential as a beneficial recreational activity. These findings support the use of HGS as a screening tool and underscore the holistic benefits of padel for amateur athletes.
