Fig. 5From: Do skeletal muscle composition and gene expression as well as acute exercise-induced serum adaptations in older adults depend on fitness status?Changes in serum concentrations of molecules involved in ageing, muscle damage and neurotrophic adaptation. HPF and LPF were examined after an acute exercise test (pre vs. post). A HSP70 showed non-significant higher basal values in HPF (p = 0.069) compared to LPF. B Plasma levels of BDNF were non-significantly higher in HPF pre and post. C Irisin concentrations were pre higher in HPF compared to LPF, but this difference was blunted post. D Serum concentration of inflammation marker Il-6 increased post in HPF and LPF. E Kynurenine did not differ in both groups, but due to an increase in LPF and a decrease in HPF post a tendency for different adaptations (p = 0.0927) was observedBack to article page
