%0 Journal Article %T Hardcastle Takes a HIT! Commentary: Why Sprint Interval Training is Inappropriate for a Largely Sedentary population. | Insight Medical Publishing %A Eduardo Caldas Costa %A Sarah J Hardcastle %J Journal Impact factor: 2.0* %D 2018 %R 10.21767/2471-7975.100032 %X Our previous paper prompted a lively debate concerning the £¿£¿£¿£¿c£¿£¿cy of sprint interval training (SIT) [1,2]. For clarification SIT refers to protocols that involve supramaximal efforts (>100% maximal oxygen uptake) and high-intensity-intervaltraining (HIIT) involves ¡®vigorous¡¯ or ¡®near-maximal¡¯ efforts (target intensity: 80% to 100% peak heart-rate) [3]. In the current commentary, we return to the role of affect and perceived effort on exercise adherence raised in the recent commentary by Jung et al. [4]. We contend that the considerable anticipated effort required to participate in SIT and aversive psychological states experienced during such 'all out' supramaximal exercise may likely to damage adherence to such protocols. %U http://behaviouralscience.imedpub.com/hardcastle-takes-a-hit-commentary-why-sprint-interval-training-is-inappropriate-for-a-largely-sedentary-population.php?aid=22598
