Short duration small-sided football and to a lesser extent whole body vibration exercise induce acute changes in markers of bone turnover

Abstract

We aimed to study whether short-duration vibration exercise or football sessions of two different durations acutely changed plasma markers of bone turnover and muscle strain. Inactive premenopausal women (n=56) were randomized to complete a single bout of short (FG15) or long duration (FG60) small-sided football or low magnitude whole body vibration training (VIB). Procollagen type 1 amino-terminal propeptide (P1NP) was increased during exercise for FG15 (51.6±23.0 to 56.5±22.5µg.l-1, mean±SD, p<0.05) and FG60 (42.6±11.8 to 50.2±12.8µg.l-1, p<0.05) but not for VIB (38.8±15.1 to 36.6±14.7µg.l-1, p>0.05). An increase in osteocalcin was observed 48h post exercise (p<0.05), which did not differ between exercise groups. C-terminal telopeptide of type 1 collagen was not affected by exercise. Blood lactate concentration increased during exercise for FG15 (0.6±0.2 to 3.4±1.2mM) and FG60 (0.6±0.2 to 3.3±2.0mM), but not for VIB (0.6±0.2 to 0.9±0.4mM) (P<0.05). Plasma creatine kinase increased by 55±63% and 137±119% 48h after FG15 and FG60 (p<0.05), but not after VIB (26±54%, NS). In contrast to the minor elevation in osteocalcin in response to a single session of vibration exercise, both short and longer durations of small-sided football acutely increased plasma P1NP, osteocalcin and creatine kinase. This may contribute to favorable effects of chronic training on musculoskeletal health.
