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/m 2 ], overweight [25 to 29.9 kg/m 2 ] and obese [≥ 30 kg/m 2 ]). Sixty-four active/trained older individuals were enrolled, and later allocated to groups according to BMI categories (normal [≤ 24.9 kg/m 2 ], overweight [25 to 29.9 kg/m 2 ] and obese [≥ 30 kg/m 2 ]). Assessments were conducted in two separate visits to the laboratory. In the first visit, participants underwent measures of height, body mass, and peak torque leg extension and flexion using an isokinetic dynamometer. On visit two, participants performed the 30-second Sit and Stand test (30SST), Timed Up and Go (TUG), and 6-minute Walk (6MW) tests. ANOVA one-way was used to analyze the data and significance was set at P < .05. One-way ANOVAs did not reveal significance differences among BMI categories for leg extension peak torque ( F (2,61) = 1.11; P = 0.336), leg flexion peak torque ( F (2,61) = 1.22; P = 0.303), 30SST ( F (2,61) =1.28; P = 0.285), TUG ( F (2,61) = 0.238; P = 0.789), and 6MW ( F (2,61) = 2.52; P = 0.089)]. Our findings indicated that for older individuals who exercise regularly, physical function tests which mimic ordinary activities of daily living, are not impacted by BMI status. Thus, being physically active may counteract some of the negative effects of high BMI observed in the older adult population. |
