Despite the benefits of increased muscle power, strength, and endurance, there is a paucity of research on these parameters in African American females (AAF). A possible reason for the lack of research regarding muscle performance in older AAF may be the view that maximal muscular testing is unsafe. Therefore, the purpose of this study was to investigate the blood pressure (BP) response, rating of perceived exertion (RPE), and rate of muscle soreness and injury associated with maximal power, strength, and endurance testing in 19 sedentary AAF (age=51.0±7.1yrs; ht=162.1±6.1cm; wt=84.8±11.3kg; %bodyfat=42.3±5.3). Tests included: modified Wingate (3.5% bodymass for 10 sec.), 1 kg medicine ball put, 1RM squat press and bench press, and repetitions to failure at 70% 1RM squat press and 50% 1RM bench press. All tests were conducted the same day. BP and RPE were assessed immediately posttest. Injuries and muscle soreness were evaluated using a soreness scale immediately posttest and days 2 and 7. No abnormal BP responses were observed (mean response to all tests=146/86mmHg). RPE ranged from fairly light (11) to very, very hard (19) for all tests. No injuries or soreness requiring any alteration in lifestyle were reported. Results indicate that maximal muscle power, strength, and endurance testing may be performed in sedentary older AAF on the same day without significant muscle soreness, injury, or abnormal BP response.
