“…Studies have shown that the plasma biomarkers glucose, insulin, and catecholamines, are elevated following bouts of high-intensity exercise as an attempt to meet metabolic demands and to maintain homeostasis in bioenergetics (Babraj et al, 2009;Adams, 2013). This metabolic response has been observed in a variety of populations ranging from sedentary to trained individuals (Whyte et al, 2013;Henriksson, 1995;Babraj et al, 2009). Traditionally, these studies have examined bouts that are of short duration and high-intensity, while utilizing single modality intervals such as cycling or running (Adams, 2013).…”

Glucose regulation is a fundamental process of metabolic function, and is acutely altered by physical activity. High-Intensity Functional Training (HIFT) is a form of exercise performed using combinations of various modalities and durations. It is unknown if the metabolic responses to HIFT are similar to more commonly studied modalities (e.g., cycling and treadmill exercise), or if exercise duration will influence glucose regulation. The purpose of this study was to determine the effect of a Short (< 5-min) and Long (15-min) bout of HIFT on plasma metabolic biomarkers. Ten apparently healthy males (28.11 ± 5.09yrs) participated in this study. Two HIFT sessions (SHORT and LONG) were performed in a crossover fashion. Blood plasma was collected at four time points: PRE, POST, 1HR, and 3HR in order to examine glucose (GLU), insulin (INS), epinephrine (E), and norepinephrine (NE) responses. No trial dependent difference between the SHORT and LONG bouts in GLU (p=0.054), INS (p=0.671), E (p=0.078), and NE (p=0.194). A time effect was observed in both bouts only at POST for GLU (p<0.001), INS (p=0.011), E (p<0.001), and NE (p<0.001). All times returned to baseline values (p>0.05), except for lowered 3HR E (p=0.007). This study demonstrated that both SHORT and LONG bouts of HIFT elicited GLU, INS, E, and NE responses similar to those reported in response to high-intensity treadmill and cycling exercise, and that duration of the HIFT bouts may not be a determining factor in glucose regulation in healthy individuals.

“…Nie et al [19] found that a single bout of HIIT (4×30s "all out" sprints, 4min recovery) improved glucose tolerance in obese men. More recently, improvement in insulin sensitivity and fat oxidation was found in overweight/obese sedentary men after a single bout of HIIT (4×30s "all out" sprints, 4.5min recovery) [20].…”

“…The Wingate protocol is extremely strenuous and uncomfortable, which is why HIIT is suited to active and motivated individuals [14][15][16][17]. However, a growing body of evidence suggests that HIIT, using the Wingate test, can be used by overweight/obese sedentary individuals [11,[18][19][20]. Whyte et al [18] found that 2 weeks of very high intensity sprint interval training (6 sessions of 4 to 6 repeats of 30s Wingate with 4-5min recovery) improved insulin sensitivity, increased resting fat oxidation, and reduced waist circumference and systolic blood pressure in overweight/obese sedentary men.…”

“…Trilk et al [11] also showed that 4 weeks of HIIT (4-7×30s "all out" sprints, 4min recovery) improved circulatory function (12% increase in VO 2max , 11.4% increase in stroke volume, and -8.1% decreases in resting heart rate) in overweight/obese sedentary women. Even a single bout of HIIT has been shown to improve obesity-related risk factors for diabetes in obese men [19,20]. Nie et al [19] found that a single bout of HIIT (4×30s "all out" sprints, 4min recovery) improved glucose tolerance in obese men.…”

High-intensity interval training (HIIT) has become a promising strategy to induce a number of metabolic adaptations and alter body composition. Recent evidence suggests that HIIT can be a time-efficient strategy to promote health in sedentary overweight/obese individuals. This may be contrary to the belief held by some health professionals that training programs at high intensity are not appropriate for optimizing fat oxidation and inducing weight loss in this population. This paper reviews the results of HIIT studies conducted with overweight/obese individuals. A special focus is on the effect of HIIT on fat oxidation and weight loss.

Background: Estrogen has protective effects on the cardiovascular system due to which there is an increase in the prevalence of cardiovascular diseases in postmenopausal women.Objective: This study was conducted to determine the effect of high intensity interval training versus moderate intensity continuous training on modulating cardiovascular disease risk factors in postmenopausal women. Participants and methods:Sixty obese hypertensive postmenopausal women participated in this study, their age ranged from 45-55 years. They were divided into two groups equal in number,(group-A; n=30) high intensity interval training group (HIT group) received high intensity interval training for 3 sessions per week for 12 weeks and (group-B; n=30) Moderate intensity continuous training group (MIT group) received moderate intensity continuous training for 3 sessions per week for 12 weeks and. Nitric oxide, blood pressure and BMI were measured before and after the study. Results:The results of this study revealed a non-statistical significant difference (P>0.05) between both groups (A&B) in nitric oxide, blood pressure and BMI before the treatment, While, there was a highly statistical significant difference (P<0.01) after treatment in favor of group (A). Conclusion:It could be concluded that HIT is more effective than MIT in improving levels of nitric oxide, blood pressure and BMI.
