description

Regarding the importance of recovery in sport performance assessment of post exercise Heart Rate HR Dynamics has become a useful tool to understand such an individual process Heart Rate Variability HRV analysis is widely used as a non invasive marker of Autonomic Nervous System regulation of HR where the nonlinear methods Detrended Fluctuation Analysis DFA have become a promising complementary analysis technique In order to deepen on the effects of supra maximal complex efforts integrating specific endurance and strength requirements on cardiac autonomic regulation our research group is working in different protocols looking for the analysis of specific responses under supra maximal exertion Therefore our purpose was to analyze the immediate min recovery timeline following a supra maximal specific Judo test in twenty four judokas from the Spanish National Team males and females plusmn years deepening on gender differences Consistent with previous research on supra maximal protocols both HRV indices and Short Term Scaling Exponent alpha stemmed from DFA appeared severely depressed after the test Moreover a negative correlation was found between final isometric pull up drill and both lnTP r p lt and lnLF r p lt thus suggesting a crucial role for isometric strength requirements in cardiac autonomic recovery after exercise At the same time while performance showed a large gender difference p lt d no significant gender differences were found either in HRV indices or in alpha However when analyzing distance scores to optimal value of alpha alpha men displayed significantly greater results thus implying an improved recovery ability Eventually our results corroborate that nonlinear methods compared to linear HRV indices are capable of detecting subtler changes in HR behaviour
