20.500.12556/DiRROS-17233 Participation in youth sports influences sarcopenia parameters in older adults Background The degree of deterioration in sarcopenia parameters may be affected by a person’s level of physical activity (PA) and sedentary behavior (SB). Our study focused on examining the PA and SB of active older adults including those with and without history of sports in youth. Methods Forty-four participants (20 men and 24 women, mean age of total sample 76.1 ± 5.2 years) were included in analysis of PA, SB habits and sarcopenia parameters, determined by skeletal muscle index, hand-grip strength, gait speed, Timed Up and Go tests (TUG). PA and SB were recorded with accelerometers. Our primary aim was to compare participants with (AH) or without a sport history in youth (NAH), in their sarcopenia parameters and PA and SB habits. Results When divided participants in two groups (AH and NAH) and adjusting for age, we have detected the differences for skeletal muscle index (p = 0.007) and hand-grip strength (p = 0.004) in favor of participants who were engaged in sports in youth. We did not find any differences in PA and SB habits between the AH and NAH groups. After adjusting for age, participants with a higher number of daily steps, longer moderate to vigorous physical activity (MVPA) bouts, a higher number of MVPA bouts in a day and higher overall MVPA engagement achieved better results in hand-grip strength and TUG. Participants with lower SB had better TUG and gait speed results. Conclusions Our findings suggest that engaging in sports activities in youth can make a difference with sarcopenia parameters. Although we found no differences in PA and SB habits between participants with AH and NAH, participants with an athlete history performed better results in sarcopenia parameters. muscles muscle disorder elderly exercise sedentarism aktivno staranje telesna aktivnost sedentarnost sarkopenija true false true Angleški jezik Slovenski jezik Copyright 2023 Teraž et al Neznano 2023-11-10 13:21:58 2023-11-10 13:22:00 2024-12-11 12:24:36 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Soavtorji: Miloš Kalc, Boštjan Šimunič, Uroš Marušič, Primož Pori, Saša Pišot, Rado Pišot; Opis vira z dne 10. 11. 2023; 17 str.
