abdominis activation was 51% less during the narrow, 50% less during the middle, and 47% less during the wide hand position bench press in comparison with activation at the parallel push-up hand positions (all values, P  < .001). Figure 1 —Normalized (mean [SD]) surface electromyography for the narrow hand

perpendicular distance between the ankle center and the line of action of the vertical component of the ground reaction force. Electromyography The use of high-density surface electromyography provides sampling from a broad area of each muscle reflecting the global activity of each muscle. High-density surface

as a preventative measure for ankle trauma by using surface electromyography to assess the effectiveness of KT at facilitating the muscle activation of fibularis longus. 2 The participants stabilized on a balance board with the tested limb as the board was subjected to perturbation from a 10-kg

individuals with CAI. Methods Design This study used a cross-over design with counterbalanced conditions in a laboratory setting. Primary independent variables were condition (BFR and control) and exercise sets (set 1, set 2, set 3, and set 4). Primary outcomes included surface electromyography (EMG) muscle

session with the longboard. Surface electromyography was used to record activity from the erector spinae (lumbar region), mid trapezius, upper trapezius, and upper latissimus dorsi muscles of the right side of each participant (Figure  2 ). Electrodes were placed as follows: erector spinae = approximately

, or musculoskeletal soft-tissue injury of the lower-extremity, such as ankle sprain within the last 6 months, were excluded. Overweight or obese subjects were also excluded, as fatty tissue, acting as a low-pass filter, could interfere with the surface electromyography (EMG) signals. 22 The subjects
