Acute post-exercise cardiovascular\ud responses in healthy participants

The overall aim of this project was to investigate the acute cardiovascular post-exercise\ud response in healthy individuals. The aim of the first study was to establish the within\ud day and between day reproducibility of supine and tilt baroreflex sensitivity (BRS)\ud utilising time (sequence) and spectral indices in 46 healthy adult\ud males employing three repeat measures; baseline, + 60 min and + 24 h. Reproducibility\ud was assessed by the 95% limits of agreement (LOA) to assess the extent of agreement\ud and an alternative approach of estimating the technical error of the measurement (TEM)\ud to assess reproducibility was also undertaken. The LOA indicated same day\ud reproducibility was marginally better than between day reproducibility for spectral\ud parameters while between day reproducibility was marginally better than same day\ud reproducibility for sequence parameters with reproducibility markedly improved across\ud all BRS outcome measures during tilt. Precision expressed by TEM for all spectral\ud outcomes was good in both supine and tilt BRS (< 6 %) although precision was lower,\ud but acceptable, for sequence BRS outcomes in both positions (< 11%). Thus, all BRS\ud outcome measures and the tilt procedure were incorporated into the exercise study. The\ud aim of the second study was to compare the response of supine and tilt BRS following a\ud single bout of moderate intensity exercise and high intensity exercise. \ud Further details are given in the full abstract above
