International Journal of Exercise Science
International Journal of Exercise Science 16(4): 1228-1243, 2023. The study aimed to investigate sex differences and the effect of physical activity on the hamstring:quadriceps (H:Q) ratio, activities of daily living (ADLs), and the Functional Movement Screen (FMS) in older adults. Thirty older adults (72.56 + 6.22) completed maximal voluntary isometric contractions (MVICs), ADLs, the FMS, and three closed-kinetic chain exercises (CKCs); front lunge (FL), side lunge (SL), and bilateral squat (BLSQ). Electromyography was recorded from the biceps femoris (BF) and vastus lateralis (VL) on the dominant and non-dominant limbs during the MVICs …

International Journal of Exercise Science
International Journal of Exercise Science 16(1): 293-303, 2023. Applying blood flow restriction (BFR) during resistance exercise is a potent stimulus of muscular adaption, but there is little direct comparison of its effect on neuromuscular function. The purpose of this investigation was to compare surface electromyography amplitude and frequency responses during a 75 (1 × 30, 3 × 15) repetition bout (BFR-75) of BFR to 4 sets to failure (BFR-F). Twelve women (mean ± SD age = 22 ± 4 years; body mass = 72 ± 14.4 kg; height = 162.1 ± 4.0 cm) volunteered for the investigation. One leg was …
