Sentences with phrase «measure joint angles»

Brandon et al. (2013) assessed the reliability of a novel analysis system for Olympic weightlifting, comprising surface electromyography (EMG) equipment (to measure EMG amplitude within a muscle), synchronised with electrogoniometry (to measure joint angles), and a barbell position transducer (to measure the height of the barbell and thereby its displacement and linear velocity).

These make it relatively simple to measure joint angles and the speed and acceleration of each limb during the throwing motion and thus to calculate the forces at each joint.

This section sets out a summary of the research that has explored the kinematics of the deadlift exercise, using motion capture analysis to measure joint angle movements.

Not exact matches

It also has onboard sensors that measure the angle of the joints to help it adjust its wing position on the go.

Sensors in each joint measure the bending angle or the degree of a twisting motion, and transfer this information to a software that computes how the virtual characters should move.

Narici et al. (1996) reported that the resting fascicle length of the medial gastrocnemius muscle was 57.0 mm and decreased to 34.0 mm depending on the joint angle measured.

Comparing the effect of shoulder joint angle, Pizzari et al. (2014) measured muscle activity in all three regions of the trapezius muscle while performing a standard dumbbell shrug with the arms by the sides or abducted 30 degrees.

This section sets out a summary of the research that has explored the net joint moments during the split squat exercise, using inverse dynamics calculations based on data from motion analysis of joint angle movements and on ground reaction forces measured using a force plate.

It can be simply measured using dynamometry by taking multiple measurements in the same dynamometer of the same joint angle movement, at different angular velocities.

On the other hand, partial squats seem better than full squats for improving some athletic performance measures, such as sprinting (Rhea et al. 2016), possibly because the joint angle - specific strength gains lead to better transfer to those activities.

Measuring peak moments helps establish the maximum turning force that can be exerted at a joint irrespective of joint angle.

The peak moment arm length of the latissimus dorsi muscle overall ranges between -21.1 to -45.0 mm depending on what region of the muscle is being measured and the joint angle.
