risk factors between different locations in injured recreational runners. Methods In this retrospective case–control analysis, 550 injured runners (49.6% female) with a medically diagnosed RRI were included. All runners had undergone an instrumented treadmill analysis to determine habitual footstrike pattern, vertical instantaneous load rate, peak vertical ground reaction force (vGRF) and…

east cancer survivors (BCS). Methods Forty-four BCS (60.3 ± 8.3 yr) were randomly assigned to the FIT or yin yoga group. Body composition and BMD were measured via dual energy x-ray absorptiometry. Blood biomarkers for bone metabolism were analyzed via enzyme-linked immunosorbent assays. Upper and lower body strength was assessed using a one-repetition maximum chest press and isokinetic knee…

the combined influence of BMI and ACLR on walking speed and gait biomechanics that are hypothesized to influence KOA onset. Methods Walking speed and gait biomechanics (peak vertical ground reaction force [vGRF], peak vGRF instantaneous loading rate [vGRF-LR], peak knee flexion angle, knee flexion excursion [KFE], peak internal knee extension moment [KEM], and peak internal knee abduction…

al function. Land walking (LW) and water walking (WW) induce distinct hemodynamic responses, so the comparison of their effects provides an approach to study shear stress effects on endothelial function. We hypothesized that LW and WW training would have different effects on peripheral artery endothelial function. Methods Fifty-one sedentary, older (age = 61.9 ± 6.6 yr, 23.5% male) individuals…

. Estimated CRF (eCRF) was determined from 2 nonexercise equations, 3 submaximal exercise equations, and 10 maximal exercise equations; all eCRF calculations were then compared with directly measured CRF, determined from a cardiopulmonary exercise test. Analysis included Pearson product–moment correlations, standard error of estimate values, intraclass correlation coefficients, Cohen κ…

h examination, including CRF based on a maximal treadmill test, components of MetSyn, and serum vitamin D levels [25(OH)D]. Participants were classified into groups of low (category 1), moderate (categories 2–3), and high (categories 4–5) CRF by age-group, as well as by clinical cut points for MetSyn and 25(OH)D. We calculated odds ratios (OR) of MetSyn across levels of CRF and 25(OH)D and also…

ss-sectional heritability estimates would be higher than estimates based on training responses. Methods DXA was undertaken in 84 same-sex untrained twins (30 monozygotic [MZ], 12 dizygotic [DZ]). Participants underwent 3 months of END and RES training, separated by 3 months washout. Twins trained in pairs. Results RES (P < 0.001) and END (P = 0.002) increased lean mass, with a greater...

) for 12 wk then began swimming exercise or remained sedentary for 8 wk. Thereafter, cardiac function was assessed by echocardiography, and heart tissue and plasma were collected for further measurements. The molecular mechanism of exercise was investigated after treating Hmgcs2 siRNA in palmitate-induced neonatal mouse cardiomyocytes. Results HFD induced myocardial hypertrophy and fibrosis…
