Sentences with phrase «hip rotation angle»

Mayer et al. (2002) investigated the effect of hip rotation angle on gluteus maximus EMG amplitude during 45 - degree back extensions.

Comparing squats with different hip rotation angles, Ninos et al. (1997) found no differences in muscle activity between squats with the feet pointing neutrally forwards and the feet turned out at 30 degrees (using the same absolute load).

Not exact matches

Although stance width appears to have no effect, greater hip external rotation angles (up to 30 degrees) appear to cause increased hip adductor muscle activity.

In contrast, Pereira et al. (2010) found that hip adductor muscle activity was increased by increasing hip external rotation angle (between 0 and 30 degrees), when using the same absolute load for each variation.

Since strength is specific, then: strength training exercises or exercise variations involving moderately flexed peak knee angles, very flexed hip and trunk angles, and some torso rotation or lateral bend may be most valuable for improving COD ability.
