Summary
This meta-analysis examined the effects of different protocols of high-intensity interval training (HIIT) on VO2max in adults. The authors included 53 randomized controlled trials (RCTs) that compared HIIT to either a control group or a moderate-intensity continuous training (MICT) group.
The results showed that HIIT was effective in improving VO2max in adults, regardless of the HIIT protocol used. However, longer interval durations (≥2 minutes), higher work volumes (≥15 minutes), and longer training periods (≥4-12 weeks) were associated with larger improvements in VO2max.
Relevance to Module 5 and the Course
This article is relevant to Module 5, which focuses on the physiological adaptations to exercise training. The article provides evidence that HIIT can be an effective way to improve VO2max, which is a key measure of cardiorespiratory fitness.
The article is also relevant to the course in general, as it provides evidence that HIIT can be a time-efficient and effective way to improve fitness. This is important for people who are short on time or who do not enjoy traditional forms of exercise.
Would I Choose HIIT to Increase Training Performance Among Sedentary Adults?
Yes, I would choose HIIT to increase training performance among sedentary adults. HIIT is a time-efficient and effective way to improve fitness, and it is well-suited for people who are new to exercise.
In addition, HIIT has been shown to have a number of other benefits, such as improved insulin sensitivity, reduced body fat, and increased muscle mass. These benefits make HIIT a good choice for people who are looking to improve their overall health and fitness.
What Other Training Method Would I Choose to Increase VO2 Max?
If I were not able to do HIIT, I would choose moderate-intensity continuous training (MICT) to increase VO2max. MICT is a more traditional form of exercise that involves working at a moderate intensity for a sustained period of time.
MICT is not as time-efficient as HIIT, but it is still an effective way to improve VO2max. In addition, MICT is a good choice for people who are not able to tolerate the high-intensity demands of HIIT.
Overall, the evidence suggests that HIIT is an effective way to improve VO2max in adults. HIIT is a time-efficient and effective way to improve fitness, and it is well-suited for people who are new to exercise. If I were not able to do HIIT, I would choose moderate-intensity continuous training (MICT) to increase VO2max.
