Introduction: Sedentary lifestyle, overweight and obesity in adult women have high prevalence.Objective: To determine the effects of a high intensity interval training program on the anthropometric profile of overweight or obese women.Materials and methods: 24 adult women, including 16 with overweight and 8 with obesity, between 26 and 49 years of age, were selected to participate in a two month high intensity training program (three sessions per week). Weight, height, BMI, muscle mass percentage, and fat mass and visceral fat percentages were assessed.Results: The adherent group (≥75% assistance) was composed by 16 participants, while the non-adherent group (assistance <75%), by 8 participants. No significant differences were found among both groups previous to and after the intervention (p≥0.05).The non-adherent group did not show any significant change, while the adherent group improved (p<0.05) their variables of weight (p<0.001), BMI (p<0.001), fat mass percentage (p<0.001), muscle mass percentage (p<0.001) and visceral fat percentage (p=0.020) after the intervention.Conclusions: The training program improved the anthropometric profile of the participants without requiring specialized equipment or involving high costs, thus, this procedure is recommended for the treatment of malnutrition by excess in this type of population.

This study sought to determine if personalized moderate-intensity continuous exercise training (MICT) combined with high-intensity interval training (HIIT) was more effective at improving comprehensive training responsiveness than MICT alone. Apparently healthy, but physically inactive men and women (n = 54) were randomized to a non-exercise control group or one of two 13-week exercise training groups: (1) a personalized MICT + HIIT aerobic and resistance training program based on the American Council on Exercise guidelines, or (2) a standardized MICT aerobic and resistance training program designed according to current American College of Sports Medicine guidelines. Mean changes in maximal oxygen uptake (VO2max) and Metabolic (MetS) z-score in the personalized MICT + HIIT group were more favorable (p < 0.05) when compared to both the standardized MICT and control groups. Additionally, on the individual level, there were positive improvements in VO2max (Δ > 4.9%) and MetS z-score (Δ ≤ −0.48) in 100% (16/16) of participants in the personalized MICT + HIIT group. In the present study, a personalized exercise prescription combining MICT + HIIT in conjunction with resistance training elicited greater improvements in VO2max, MetS z-score reductions, and diminished inter-individual variation in VO2max and cardiometabolic training responses when compared to standardized MICT.

Abstract Background/objectives: Visceral obesity is one of the key features of metabolic syndrome. High-intensity interval training (HIIT) could effectively reduce visceral fat but its effects show strong heterogeneity in populations with different obesity degree. The mechanism may be related to the differential adaptation to training between obesity phenotypes, namely obesity prone (OP) and obesity resistant (OR). The aim of the present study was to compare adaptive changes of visceral adipose lipolysis adaptation to HIIT between OP and OR animals and further explore the upstream pathway.Methods: OP and OR Sprague Dawley rats were established after feeding a high-fat diet for 6 weeks; they were then divided into HIIT (H-OP and H-OR) and control (C-OP and C-OR) groups. After 12 weeks of HIIT or a sedentary lifestyle, animals were fasted for 12 h and then sacrificed for histology as well as gene and protein analysis. Visceral adipocytes were isolated without fasting for catecholamine stimulation and β3-adrenergic receptor (β3-AR) blockade in vitro to evaluate the role of upstream pathways.Results: After training, there were no differences in weight loss or food intake between OP and OR rats (P > 0.05). However, the visceral fat mass, adipocyte volume and liver lipid of OP rats decreased more than that of OR rats (P < 0.05). Meanwhile, the cell lipolytic capacity and the increase in the expression of β3-AR was higher in the OP compared with OR groups (P < 0.05). Although training did not increase sympathetic nervous system activity (P > 0.05), the cell sensitivity to catecholamine increased significantly in the OP compared with OR groups (P < 0.05). After blocking β3-AR, the increased sensitivity disappeared.Conclusion: With HIIT, OP rats lost more visceral fat than OR rats, which was related to stronger adaptive changes in lipolysis. Increased β3-AR expression, rather than altered sympathetic nerve activity, mediated this adaption.

Background and Purpose The purpose of this case report is to describe the responses of 4 patients with chronic heart failure (CHF) to a novel rehabilitation program: a group-based, high-intensity, interval-training program that includes aerobic, resistance, flexibility, and balance activities. Case Descriptions Four patients (55–71 years of age) with CHF (New York Heart Association class III) participated in the rehabilitation program twice per week for 16 weeks. Outcome measures included a 6-minute walk test (6MWT), a cycle ergometer test (aerobic capacity), and a quality-of-life questionnaire. Outcomes Patients 1, 2, and 3 increased their aerobic capacity (17%, 25%, and 52%, respectively). Patient 4 did not complete the cycle ergometer test because of limitations associated with his pacemaker. All patients increased their 6MWT distance (117, 66, 135, and 143 m for patients 1, 2, 3, and 4, respectively). No adverse events were reported. Discussion The Norwegian Ullevaal Model of cardiac rehabilitation is a novel high-intensity, interval-training program. The 4 patients with CHF in this case series who participated in this program experienced improvements in physical capacity and quality of life and had no adverse events. These results are consistent with recent evidence supporting the efficacy of high-intensity interval training in people with CHF. Randomized clinical trials are needed to evaluate the clinical efficacy of this group-based, high-intensity, aerobic interval-training program for patients with CHF.
