Handgrip strength (HGS) is an often-used assessment of overall strength in older adults in part because it is easy to administer, standards have been developed for the older population, and strength of the

of caffeine among athletes, its effects on strength and power performance remain inconsistent ( Duncan et al., 2013 ; Grgic et al., 2020 ; Sabol et al., 2019 ). For example, 5 mg/kg of caffeine had no effect on handgrip strength in 14 male judo athletes ( da Silva Athayde et al., 2018 ), but

muscle mass is associated with reduced strength ( Kamel, 2003 ). Handgrip strength is a simple and reliable test of physical fitness and is a predictor of overall muscle strength, sarcopenia, and physical health ( Bohannon, 2015 ). Weak handgrip strength is associated with all-cause mortality and

(Microgate, Bolzano, Italy). The second day was devoted to jumping (squat jump, countermovement jump, countermovement jump with arms, and horizontal 5-jump tests) followed by dominant and nondominant handgrip strength assessments. On the third day, anthropometric measurements were followed by determinations

There is a general agreement that handgrip strength (HGS) is an important criterion for diagnosing sarcopenia in older adults 1 , 2 because the age-related decline in HGS is a simple and powerful predictor of future disability and mortality. 3 , 4 However, one potential issue is that studies

The aim was to analyze the influence of competitive round on muscle strength, body-fluid balance, and renal function in elite badminton players during a real competition. Body mass, jump height during a countermovement jump, handgrip force, and urine samples were obtained from 13 elite badminton players (6 men and 7 women) before and after the 2nd-round and quarterfinal matches of the national Spanish badminton championship. Sweat rate was determined by using prematch-to-postmatch body-mass change and by weighing individually labeled fluid bottles. Sweat rates were 1.04 ± 0.62 and 0.98 ± 0.43 L/h, while rehydration rate was 0.69 ± 0.26 and 0.91 ± 0.52 L/h for the 2nd round and quarterfinals, respectively. Thus, dehydration was 0.47% ± 1.03% after the 2nd round and 0.23% ± 0.43% after the quarterfinals. There were no differences in prematch-to-postmatch jump height, but jump height was reduced from 37.51 ± 8.83 cm after the 2nd-round game to 34.82 ± 7.37 cm after the quarterfinals (P < .05). No significant differences were found in handgrip force when comparing prepost matches or rounds, although there were significant differences between dominant and nondominant hands (P < .05). The succession of rounds caused the appearance of proteinuria, hematuria, glycosuria, and higher nitrite and ketone concentrations in urine. Rehydration patterns during a real badminton competition were effective to prevent dehydration. A badminton match did not affect jump height or handgrip force, but jump height was progressively reduced by the competitive round. Badminton players’ renal responses reflected diminished renal flux due to the high-intensity nature of this racket sport.

European Working Group on Sarcopenia in Older People recommended the use of handgrip strength as the most practical measure of generalized muscle strength ( Cruz-Jentoft et al., 2010 ). A decline in handgrip strength has been associated with an increased risk of morbidity, disability, and mortality
