Peak Power And Body Mass As Indices Of Bone Loading In A Healthy Adult Population

Repeated and intentional loading of the skeletal system stimulates an adaptive osteogenic response. Body mass bone strength are strongly associated because increase in body increases on during locomotion. However, effective for adaptation includes dynamic higher load rates, suggesting that a neuromuscular muscle fitness test may be stronger predictor (Rantalainen et al 2010). PURPOSE: To examine whether peak vertical jump power at take-off is more predictive indices (BSIc SSIp) than mass. We hypothesized would appropriate index METHODS: 142 participants (79 F, 63 M) performed maximal test. Peak was calculated from height using Sayer’s equation. Bone compression (BSIc) polar strain (SSIp) were measured peripheral quantitative computed tomography (pQCT) dominant tibia 4% 50% sites respectively. Two hierarchical multiple regression analyses with as dependent variables. In first step age, height, mass, sex entered into model variables, while second step. RESULTS: The correlations between BSIc SSIp (r = 0.643, r 0.711, p < 0.001) those 0.435, 0.658, 0.001). including sex, explained 42% (p variance 58.7% variance. addition to increased explanatory by 7.2% 1.1% SSIp. For BSIc, contributed (i.e. 0.541 vs. -0.102 standardized β-values). contribution decreased 12.9% similar effect 0.257 0.006) 0.213 0.051)). CONCLUSION: power, assessments, better surrogate assessing predicting compared
