This study examined sex-specific responses during self-paced, high-intensity interval training (HIIT). Sixteen (8 men and 8 women) individuals completed a peak oxygen uptake test and 3 treadmill HIIT sessions on separate days. The HIIT sessions consisted of six 4-minute intervals performed at the highest self-selected intensity individuals felt they could maintain. Recovery between intervals wa...

BACKGROUND The aim of this study was to investigate the effects of High-Intensity Interval Training (HIIT) on nitric oxide metabolites (NO2(-), NO3(-)) and myocardial infarct size after Ischemia/Reperfusion (I/R) injury in healthy male rats. METHODS A total of 44 Wistar rats were randomly divided into 4 groups including HIIT (n=8), HIIT + IR protocol (n=14), control (n=8), and control + IR (n...

objective(s):high-intensity interval training (hiit) increases energy expenditure and mechanical energy efficiency. although both uncoupling proteins (ucps) and endothelial nitric oxide synthase (enos) affect the mechanical efficiency and antioxidant capacity, their effects are inverse. the aim of this study was to determine whether the alterations of cardiac ucp2, ucp3, and enos mrna expressio...

Exercise adherence is affected by factors including perceptions of enjoyment, time availability, and intrinsic motivation. Approximately 50% of individuals withdraw from an exercise program within the first 6 mo of initiation, citing lack of time as a main influence. Time efficient exercise such as high intensity interval training (HIIT) may provide an alternative to moderate intensity continuo...

Interval training refers to the basic concept of alternating periods of relatively intense exercise with periods of lower-intensity effort or complete rest for recovery. Low-volume interval training refers to sessions that involve a relatively small total amount of exercise (i.e. ≤10 min of intense exercise), compared with traditional moderate-intensity continuous training (MICT) protocols that...

Background and Aim Adropin is a new hormone plays an important role in improving lipid metabolism vascular protection. The current study aims to determine the effect of eight weeks high-intensity interval training (HIIT) on level nitric oxide (NO) metabolites overweight men. Methods & Materials This quasi-experimental with pre-test/post-test design. Participants were 32 men (Mean±SD age: 30...

Abstract Introduction: Recently, it has been proposed that combining transcranial direct current stimulation (tDCS) with cardiovascular exercise (CE) may lead to positive synergies in motor and cognitive performance due assumed synergistic mechanisms on several brain levels (Steinberg, Pixa & Fregni, 2019). However, the neurophysiological effects of a combined application are currently unknown....

AIMS High-intensity interval training (HIIT) leads to improvements in various markers of cardiometabolic health but adherence to HIIT following a supervised laboratory intervention has yet to be tested. We compared self-report and objective measures of physical activity after one month of independent exercise in individuals with prediabetes who were randomized to HIIT (n = 15) or traditional mo...
