Exercise & HRV

Exercise & HRV

successful endurance program require the appropriate training stimulus relative to the physicla status of the individual, coupled with adequate recovery periods (Buscheit, 2010).
1. failure to maintain this equalibrium can rapidly lead to undesirable consequences including, stagnation or decrease in performance, or development of fatigue and over training
The ANS may play a vital role in the training response (Hautala et al., 2003, 2004 & 2009)
1. May provide information about the functional adaptations occuring within a training stimulus (Pichot et al. 2002; Iwasaki et al. 2003; Buchheit et al. 2008; Lamberts et al. 2009a, c)
2. The higher the vagal modulation the higher the training response (Hautala et al., 2003)
3. suggested that at least 4 weeks are needed to observe a training effect on cardiac parasympathetic function (sandercock 2005)
How the ANS is measured
1. The PNS can be measured using the HF power indices within the contructs of HRV, at rest or post exercise
  1. Can also be indirectly asociated with HRR
  2. Vagal related indices as well as exercise HRn post exercise HRR and HRV demonstrate that the cardiac ANS system responds and promotes adaption changes in training loads and fitness
    1. Suggesting that the vagal related measurements can predict sporting performance (Buchheit et al. 2008; Lamberts et al. 2009a, b, c)
