International Journal of Exercise Science 15(4): 373-385, 2022. Obesity induces several disorders, such as android obesity, insulin resistance, and coronary/peripheral artery disease, and obese individuals commonly have low adherence to training programs. Exercise at self-selected intensity is a feasible strategy to avoid dropouts of training routines. We aimed to assess the effects of different training programs at self-selected intensity on body composition, ratings of perceived exertion (RPE), feelings of pleasure and displeasure (FPD) and fitness outcomes (maximum oxygen uptake (VO2max) and maximum dynamic strength (1RM)) in obese women. Forty obese women (n = 40; Body Mass Index: 33.2 ± …

International Journal of Exercise Science 15(3): 330-340, 2022. This study examined the potential impact of BMI on physical function and lower-extremity muscle strength (leg extension and flexion peak torque) performance in active/trained older individuals. Sixty-four active/trained older individuals were enrolled, and later allocated to groups according to BMI categories (normal [≤ 24.9 kg/m2], overweight [25 to 29.9 kg/m2] and obese [≥ 30 kg/m2]). Sixty-four active/trained older individuals were enrolled, and later allocated to groups according to BMI categories (normal [≤ 24.9 kg/m2], overweight [25 to 29.9 kg/m2] and obese [≥ …
