Short–duration workouts became common over the past many years because the time–crunched hunt down effective ways in which to exercise. Recent analysis adds additional support for the advantages of quick workouts and indicates that less could even be additional, provided you have got acceptable instrumentality.
This data comes from a meta–review of thirty eight sprint interval coaching (SIT) trials involving 418 folks. To be eligible for the review, studies required to last a minimum of a pair of weeks, with participants finishing a minimum of 2 repetitions of sprints at supramaximal intensity exploitation specialised cycle machines. The sprints during this review lasted ten, fifteen or twenty seconds. VO2max measures were taken before and when the sprint session.
Analysis unconcealed "an overall doubtless giant result of AN 'average' SIT protocol on VO2max." 2 repetitions gave the impression to be the proper range to elicit the best response; returns diminished with future repetitions.
The review authors suggested that this information could help motivate inactive people to exercise. "Considering the low physical activity levels in the general population, and the fact that lack of time is consistently identified as one of the main perceived barriers to becoming and remaining physically active, this finding has implications for the design of practical SIT interventions for improving general health," the authors wrote.
They acknowledged that reaching such high intensities is difficult and highlighted the importance of keeping repetitions to a minimum. "Our observation that reducing the number of sprint repetitions will not attenuate the increase in VO2max associated with SIT, and in fact may possibly improve the effect, is an important novel finding."
