Low-Frequency HIIT Improves Body Composition and Aerobic Capacity in Overweight Men

This study compared the effects of different frequencies of HIIT with those of moderate-intensity continuous training (MICT) on body composition in overweight or obese adults. Methods Fifty-six overweight or obese (body mass index = 26.4 ± 2.9) men between 18 and 30 yr old (age = 22.8 ± 3.1 yr) were randomly assigned to the following groups: no-intervention control (CON; n = 14), MICT performed thrice weekly (MICT×3/wk; n = 9), HIIT performed thrice weekly (HIIT×3/wk; n = 14), HIIT performed twice weekly (HIIT×2/wk; n = 10), and HIIT performed once weekly (HIIT×1/wk; n = 9). Each HIIT session consisted of 12 × 1-min bouts at 90% heart rate reserve, interspersed with 11 × 1-min bouts at 70% heart rate reserve. Aerobic capacity, body composition, resting heart rate, vascular function, insulin resistance, and biomarkers of metabolic syndrome risk factor were examined at baseline, after 4 wk, and after 8 wk of intervention. Results Aerobic capacity and percent fat-free mass significantly increased in all exercise groups compared with those in the CON group (CON vs all exercise groups, P

Conclusion: There was a high prevalence of MetS and abnormal ECG among the studied population. Abnormal ECG findings were more common in men with no differential association in people with or without MetS. However, a significant association existed between certain components of MetS and ECG abnormalities in men only. Male gender and HDLc were independent predictors of ECG Abnormalities.Keyword: Electrocardiography, metabolic syndrome, africans.

In this study, we examined 1,182 subjects (658 men and 524 women, 62.3 ± 11.7 years on average) who underwent voluntary health check-ups and sought to determine the optimal cut-off value of WC for predicting carotid IMT thickness. Receiver operating characteristic curve analysis of WC was utilized to predict high carotid IMT (defined as carotid IMT ≥ 1.1 mm). We determined that the appropriate WC cut-off value was a WC ≥ 79 cm for men and women. There was a statistically significant difference in the prevalence of high carotid IMT between WC ≥ 79 cm and WC

Shanura Fernando, BoMi Ryu, Ginnae Ahn, In-Kyu Yeo, You-Jin JeonAbstractBackgroundMetabolic syndrome (MS) defines a group of severe comorbidities, including insulin resistance, abnormal fat accumulation, and high blood pressure that lead to obesity, diabetes, and heart diseases. MS has received a growing concern due to its rising prevalence in many countries. The consumption of high-calorie food, sedentary lifestyle habits, genetic factors, and stress conditions aggravate risk factors for developing metabolic syn...

Hyperuricaemia refers to an abnormally high concentration of uric acid in serum [1], typically defined as>7  mg/dL (416 μmol/L) in men and>6  mg/dL in women [1]. Mean serum uric acid has increased progressively over the last century in many populations and the prevalence of hyperuricemia increases with age and is higher in men than premenopausal women [1], as oestrogen increases urate excretion by the kidneys. Hyperuricaemia is usually discussed in the context of gout, but it is increasingly recognised that serum uric acid values>5.0  mg/dL (men) or 4.5 mg/dL (postmenopausal women) are clinically rele...
