Grip width affects the shoulder angle during the sticking region in the bench press, where shoulder
abduction angle is more acute and flexion angle is greater at the start of the sticking region using a narrow grip compared to medium and wide grip widths.
Using a wide or narrow grip width causes differences in the shoulder
abduction angle, which are probably what leads to the stress being placed on different parts of the pectoralis major muscle.
The effect of hip
abduction angle on gluteus medius EMG activity during performance of the single - leg glute bridge exercise has been investigated (Lee et al. 2013b).
Increasing hip
abduction angle during several multi-joint hip extension exercises has been found to lead to increased gluteus medius muscle activity.
They reported no difference in the shoulder
abduction angle at the point of minimal velocity of approximately 65 degrees.
Shoulder
abduction angles are more acute in the narrow grip bench press.
Shoulder
abduction angles are more acute when performing the narrow grip bench press.
In contrast, Webb et al. (2012) reported that the anterior deltoid displays a minimum muscle moment arm at small
abduction angles and rises with increases in angle elevation.
Not exact matches
This is likely due to the vertical displacement of the bar at the start of the sticking point and resulting shoulder
abduction and elbow flexion
angles, and therefore, the sticking region of unsuccessful attempts starts earlier in the ascending phase compared with successful lifts.
The bench press grip width appears to affect peak shoulder
abduction and horizontal flexion
angles that correspond to key regions in the bench press, such as the sticking region.
Similarly, Fujisawa et al. (2014) found that hip flexion
angle did not affect gluteus medius muscle activity when the knee was in full extension during isometric hip
abduction.
During hip
abduction, a greater hip flexion
angle seems to lead to greater gluteus maximus EMG amplitude.
This study explored how both upper and lower gluteus maximus activation are affected by hip flexion
angle when performing hip
abduction.
The results show that operated dogs had significantly lower peak vertical, peak propulsive, and impulse propulsive forces on the limb and lower
angles of hip joint
abduction and extension than did normal dogs.
Although all owners subjectively expressed complete satisfaction with results of surgery at the end of the study, operated dogs still had objectively significantly lower peak vertical, peak propulsive, and impulse propulsive forces and lower
angles of hip joint
abduction and extension than did control dogs at day 120.
The hypothesis of the study was that promotion of active physical therapy during the first postoperative weeks combined with administration of an NSAID would minimize the reduction of mobility and, therefore, result in treated dogs having greater impulse propulsive forces and hip joint
abduction and extension
angles than dogs receiving a placebo.
