Physiological and Health-Related Adaptations to Low-Volume Interval Training: Influences of Nutrition and Sex
Reads0
Chats0
TLDR
Both low-volume SIT and HIIT constitute relatively time-efficient training strategies to rapidly enhance the capacity for aerobic energy metabolism and elicit physiological remodeling that resembles changes normally associated with high-volume MICT.Citations

Physiological adaptations to low-volume, high-intensity interval training in health and disease
TL;DR: Some of the mechanisms responsible for improved skeletal muscle metabolic control and changes in cardiovascular function in response to low‐ volume HIT are reviewed and insight is provided on the utility of low‐volume HIT for improving performance in athletes.

Is high-intensity interval training a time-efficient exercise strategy to improve health and fitness?
Jenna B. Gillen,Martin J. Gibala +1 more
TL;DR: Low-volume HIIT is a time-efficient exercise strategy that warrants consideration by health practitioners and fitness professionals, given that "lack of time" remains one of the most commonly cited barriers to regular exercise participation.

Update on the effects of physical activity on insulin sensitivity in humans.
Stephen R. Bird,John A. Hawley +1 more
TL;DR: Evidence is provided that regular PA reduces the risk of insulin resistance, metabolic syndrome and type 2 diabetes, and SI improves when individuals comply with exercise and/or PA guidelines, although these findings are not unanimous.

Circulating Testosterone as the Hormonal Basis of Sex Differences in Athletic Performance.
David J. Handelsman,David J. Handelsman,Angelica Lindén Hirschberg,Angelica Lindén Hirschberg,Stéphane Bermon +4 more
TL;DR: Based on the nonoverlapping, bimodal distribution of circulating testosterone concentration (measured by liquid chromatography–mass spectrometry)—and making an allowance for women with mild hyperandrogenism, notably women with polycystic ovary syndrome)—the appropriate eligibility criterion for female athletic events should be a circulating testosterone of <5.0 nmol/L.
Journal ArticleDOI
Separate Effects of Intensity and Amount of Exercise on Interindividual Cardiorespiratory Fitness Response
TL;DR: For a fixed amount of exercise, increasing exercise intensity consistent with consensus recommendations eliminated CRF nonresponse and low-intensity exercise may not be sufficient to improve CRF for a substantial proportion of sedentary obese adults.

Correlates of adults' participation in physical activity: review and update.
TL;DR: There remains a need to better understand environmental influences and the factors that influence different types of PA and longitudinal and intervention studies will be required if causal relationships are to be inferred.

Exercise Metabolism and the Molecular Regulation of Skeletal Muscle Adaptation
TL;DR: The metabolic responses and molecular mechanisms that underpin the adaptatation of skeletal muscle to acute exercise and exercise training are reviewed.
