| Popis: | Objectives: To compare muscle power between youth who acquired HIV perinatally and HIV unexposed uninfected (HUU) youth. Methods: We assessed muscle power (relative to body mass, Pmax/mass), muscle force normalized to body weight (Fmax/BW), force efficiency, jump height (Hmax) and velocity (Vmax) during a single two-legged jump with hands on waist on a force platform (Leonardo) in HIV+ youth (n=35, 9-21 y). Thirty-three and 22 participants returned at 12- and 24-months, respectively. We compared age- and sex-specific z-scores in the HIV+ youth to those in HUU controls (n=716, 9-21 y) adjusting for height and muscle cross-sectional area (MCSA, by pQCT). Results: At baseline, z-scores for Pmax/mass, Fmax/BW and Vmax were less than 1 standard deviation lower than HUU after adjusting for height and MCSA (p |
