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).
- 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)
- 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)
- The higher the vagal modulation the higher the training
response (Hautala et al., 2003)
- suggested that at least 4 weeks are needed to observe a training effect on cardiac parasympathetic function (sandercock 2005)
- How the ANS is measured
- The PNS can be measured using the HF
power indices within the contructs of HRV,
at rest or post exercise
- Can also be indirectly asociated with HRR
- 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
- Suggesting that the vagal related measurements can
predict sporting performance (Buchheit et al. 2008;
Lamberts et al. 2009a, b, c)
