This book was released on 2013 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular diseases (CVD) and type 2 diabetes are a major health and economic burden on society and without intervention, incidence will continue to increase. High intensity interval training (HIIT) is emerging as a time efficient strategy for improving risk factors of CVD and type 2 diabetes; however, there is a lack of research on HIIT in sedentary, at-risk individuals. Whilst HIIT has shown superior improvement in CVD risk factors, when compared with continuous moderate intensity exercise training (CMIET), it may be unrealistic to exclusively adopt this form of training as a lifestyle change. PURPOSE: The purpose of this study was to compare how 12 weeks of HIIT and CMIET affected cardiorespiratory fitness (VO2max), insulin sensitivity and other risk factors for CVD, in sedentary individuals at moderate risk of CVD. METHODS: Twenty nine sedentary subjects at moderate risk of CVD were recruited for 12 weeks of exercise training. Subjects were randomised into three groups: HIIT (n=9; 8-12 x 60 sec at 100% VO2max, 150 sec active recovery), CMIET (n=10; 30 min at 45-60% oxygen consumption reserve (VO2R)) and a sedentary control group (n=10). Participants in the HIIT group performed a single weekly bout of HIIT and four weekly sessions of CMIET, whilst the CMIET group performed five weekly CMIET sessions. Cardiorespiratory fitness, insulin sensitivity (HOMA model), blood lipids, body composition and quality of life were measured pre and post intervention. Probabilistic magnitude-based inferences were determined to assess the likelihood that the true value of the effect represented substantial change. RESULTS: Relative VO2max increased by 10.1% in in the HIIT group (32.7 ± 9.2 to 36.0 ± 11.5 mL·kg-1·min-1) and 3.9% in the CMIET group (33.2 ± 4.0 to 34.5 ± 6.1 mL·kg-1·min-1), whilst there was a 5.7% decrease in the control group (30.0 ± 4.6 to 28.3 ± 6.5 mL·kg-1·min-1). It was 'unclear' if a clinically significant difference existed between the HIIT and CMIET groups. There was a decrease in insulin sensitivity for both exercising groups (HIIT: 101 ± 27.3 to 90.3 ± 29.0%; CMIET: 95.6 ± 42.6 to 84.1 ± 25.6%), with a 'possibly trivial' clinical inference between groups. CONCLUSION: Both exercising groups showed clinically meaningful improvements in VO2max, body composition (hip and waist circumference), systolic and diastolic blood pressure and total and LDL cholesterol. However, it remains 'unclear' whether one type of exercise training regimen elicits a superior CVD risk factor reduction relative to its counterpart.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate the role exercise intensity plays in reducing body weight and percent body fat in overweight women. Subjects were randomized to either a high intensity interval training group (IT) or a lower intensity steady state training group (ST). Each group exercised 3 times per week for 8 weeks and expended 300 kcal per exercise session. VO2max, body composition, and resting metabolic rate (RMR) were measured pre and post training. RMR was measured after exercise at week 2 to see if intensity levels affected RMR. VO2max and body composition improved in IT but not in ST. Neither group showed a change in RMR from pretest to posttest; however, IT had an increase in RMR 24 hours post-exercise whereas ST did not. These findings show that high intensity interval exercise produces improvements in body composition, fitness, and acute RMR compared to low intensity steady state training.

Book excerpt: Are animals designed economically? The theory of symmorphosis predicts that the size of the parts in a system must be matched to the overall functional demand. Weibel shows how animals as different as shrews, pronghorns, dogs, goats--even humans--all develop from essentially the same blueprint by variation of design.

This book was released on 2021 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: A growing body of literature indicates that women, in comparison to men, report significantly more barriers to exercise, often times related to perceived lack of time due to their social roles (e.g. family responsibility, childcare). Therefore, it has been considered that exercise programs that require less time commitments would be more attractive for women to alleviate this concern. Objective: This review was conducted to comprehensively understand the present literature surrounding women and such a time-efficient protocol: high intensity interval training (HIIT). The primary aim was to determine the impact of HIIT on both cardiorespiratory fitness (CRF) and body composition. The secondary aim was to identify what variables, if any, influence the effect of HIIT on changes in CRF and body composition. Methods: A database search was conducted in MEDLINE (PubMed), CENTRAL (Cochrane), and ESCO (SPORTdiscus) to obtain all peer-reviewed publications up until November 2020. Studies were included if HIIT protocols were aerobic-based, a minimum of two weeks in duration, participants were between the ages of 18-65 years and free from cardiovascular, metabolic, or renal disease and cancers. Comparisons were made for changes in maximal or peak oxygen consumption (VO2max or VO2peak), fat mass (FM), fat-free mass (FFM), and body fat percentage (BF%). Results: 41 studies were included in this review, involving a total of 628 female subjects who were predominantly younger (582 subjects between ages 18-35 years) and overweight (body mass index ranging from 20.3-35.7 kg-m-2). Exercise intervention duration ranged from 2-15 weeks (7.8±3.7 weeks), utilizing between 2-5 sessions (3.1±0.4 visits) per week. Of the 37 studies with CRF as an outcome measures, 34 reported improvements. 35 studies reported pre- and post-intervention assessments surrounding body composition. 14 determined significant improvements in BF% and 12 studies reported a significant decrease in FM, six showed significant increases in FFM. Conclusion: It is suggested that HIIT can significantly improve CRF in women, irrespective of age, training status, BMI, and training frequency. However, exercise intervention duration, in conjunction with the appropriate intensity of exercise may influence the improvements. HIIT interventions that are shorter in duration (≤7 week) should consider utilizing intensities >100% VO2max (supramaximal) to elicit improvements in CRF. Intensities ranging from 85-95% VO2max are sufficient to augment CRF in interventions exceeding 7 weeks. The effect of HIIT on body composition is less clear. Excess post-exercise oxygen consumption (EPOC) and energy expenditure greatly exceeding 1000 MET-minutes per week may account for reductions in FM. However, there is no guarantee that these reasons alone account for all reductions in FM. There were improvements in FFM across very few studies (n = 6). It is suggested that aerobic-based HIIT be supplemented with resistance training to generate superior improvements in FFM. Furthermore, lack of controlled diet across all studies makes it difficult to determine if caloric intake could account for any changes in body composition. While HIIT may be an effective and time-efficient protocol for women, future research should focus on ecological validity and women’s adherence to such vigorous training, specifically within non-athletic and sedentary subgroups.
