significant improvement was seen in estimated VO2max in the TCC group (TCC versus SCG P = 0.003, TCC versus
BWG P = 0.08). The mean within-person change of high-frequency power in normalised units (HFnu) increased [8.2
(0.14–16.3)], representing increased parasympathetic activity, and low-frequency power in normalised units (LFnu) decreased
[–8.7 (–16.8–0.5)], representing decreased sympathetic activity, in the TCC group only. Significant gains were also seen in the
non-dominant knee extensor strength and single-leg stance time (TCC versus BWG P
