Greater effects of high- compared with moderate-intensity interval training on cardio-metabolic variables, blood leptin concentration and rating of perceived exertion in obese adolescent females was published in 2015. To the best of the researcher’s knowledge, this kind of study has not been done before and hypothesized that the HIIT would produce a more improvement in leptin levels, cardiorespiratory fitness and the participant’s rate of perceived exertion (RPE) after a HIIT workout. Their methods and procedures were similar to other studies completed. The authors recruited forty-seven obese but otherwise healthy young women with a relatively similar body mass index (BMI), age and body fat level. The researchers separated the…show more content…
In comparing the two workout groups, they both had a positive effect in almost every area tested, with the HIIT group having a more significant result in every area except blood leptin and maximal oxygen uptake. See chart below. ( Racil, Coquart, Elmontassar, Haddad, Goebel, Chaouachi, Chamari, 2016) Study Four A group of researchers from the Department of Circulation and Medical Imaging, Faculty of Medicine, Norwegian University of Science and Technology. Conducted a study called Effects of High-Intensity Interval Training and Strength Training on Metabolic, Cardiovascular and Hormonal Outcomes in Woman with Polycystic Ovary Syndrome: A Pilot Study. To the Authors knowledge such as study had not been completed. Exercise and lifestyle changes are suggested for women with polycystic ovary syndrome, but little is known about the best exercise mode, intensity and frequency for this syndrome, so they ran a ten-week randomized study to get some answers. Polycystic ovary syndrome, is a metabolic disorder, ordinarily found in women of child-bearing age, and is commonly associated with insulin resistance, dyslipidemia, and hyperinsulinemia and are grouped similar to the symptoms of metabolic syndrome. Polycystic ovary syndrome is the leading cause of infertility These women also have a higher prevalence of central adiposity and a higher risk of CVD. The study group was a relatively small population sample size and consisted of thirty-one women who had
