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...

Heart transplantation (HTx) is considered an efficient and gold-standard procedure for patients with end-stage heart failure. After surgery, patients have lower aerobic power (VO2max) and compensatory hemodynamic responses. The aim of the present study was to assess through a systematic review with meta-analysis whether high-intensity interval training (HIIT) can provide benefits for those para...

Background: Research on the effects of interval training lipid profile and hematological indices is limited. Objectives: Therefore, purpose this study was to determine eight weeks high-intensity (HIIT) moderate-intensity continuous (MICT) aerobic performance, body composition, profile, in overweight adolescents. Methods: Thirty boys (13 - 16 years) participated were randomly divided into three ...

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: 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...

It has been suggested that the time spent at a high stroke volume (SV) is important for improving maximal cardiac function. The aim of this study was to examine the effect of recovery intensity on cardiovascular parameters during a typical high-intensity interval training (HIIT) session in fourteen well-trained cyclists. Oxygen consumption (VO2), heart rate (HR), SV, cardiac output (Qc), and ox...

Introduction: Although exercise training and herbs consumption have protective effects on many diseases, the mechanism of action of exercise training with different intensities and citrus aurantium (CA) extract consumption on the autophagy-dependent MyoD activation pathway is not yet known. The aim of this study was to investigate the effect of eight weeks of moderate intensity continuous train...

The use of endurance regimens could be improved by defining their respective effectiveness on aerobic fitness and brain health that remains controversial. We aimed at comparing work-matched high-intensity interval training (HIIT) with moderate-intensity continuous (MICT) performance muscular plasticity markers in healthy rats. Cognitive functions were also investigated following the 8-week trai...

Background: Exercise training and crocin, as a herbal antioxidant, help improve metabolism insulin sensitivity in type 2 diabetes mellitus (T2D). AMP-activated protein kinase (AMPK) nuclear respiratory factor 1 (NRF1) involve the mitochondrial biogenesis pathway control. Objective: This study aimed to investigate effects of high-intensity interval (HIIT), low intensity continued (LICT) combinat...

High-intensity interval training (HIIT) improves peak power output (PPO) in sedentary aging men but has not been examined in masters endurance athletes. Therefore, we investigated whether a six-week program of low-volume HIIT would (i) improve PPO in masters athletes and (ii) whether any change in PPO would be associated with steroid hormone perturbations. Seventeen male masters athletes (60 ± ...
