Sentences with phrase «joint angles when»

Comparing the effects of different training variables, Swinton et al. (2011a) found that there was no difference in peak knee joint angles when using relative loads ranging between 10 — 80 % of 1RM with the straight bar and hexagonal bar deadlifts.

Comparing the effects of barbell type, Swinton et al. (2011a) found that there was no difference in peak joint angles when comparing straight bar and hexagonal bar deadlifts.

Not exact matches

When you lie on your back and put your legs up on a block or chair, it causes a symmetrical right angle posture at the knee joint.

You can't see it, but when you hold a plank or other isometric pose, muscle fibres are pulled from both ends of the contracting muscle — not just one section — meaning your body recruits more muscle fibres than if you were changing the joint angle.

While low bar back squats do target the lower body, the mechanics and joint angles trained during the low bar back squat are significantly different than those needed when doing front squats, cleans, and high bar back squats.

• Extension → When bones around a joint are moved further apart, decreasing the joint angle.

A common mistake people make when doing this exercise is raising the leg too high, so you want a maximum angle of about 45 degrees otherwise you not target the correct muscles (due to the physiology of the hip joint).

For example, Peak knee joint angles become more flexed when going faster (Vanrenterghem et al. 2012; Spiteri et al. 2013), probably because the lower position allows athletes to display a more horizontal direction of braking and propulsive forces.

When sprinting, one the initial early acceleration phase has been completed, the joint angles of the hip and knee during the ground contact phase range from 30 degrees of flexion through to full extension.

As explained above, COD maneuvers most commonly involve force production when the hip extensors and knee extensors are at moderate muscle lengths (although the exact joint angles can vary widely between individuals and tasks).

And when athletes perform COD maneuvers in an unplanned situation, the knee joint angles are more flexed (Besier et al. 2001a).

When different studies use the same joint angle for measurement, these can be compared to one another so long as differences between the populations tested are acknowledged.

The bench or some kind of box should be high enough to allow an angle of 90 degrees at your knee joint when your foot is on the box.

In several of the above joint angle combinations, gluteus maximus EMG amplitude is higher when muscle fibers are shorter.

This study tested muscle activation during maximum voluntary contractions of hip extension, in different hip flexion joint angles while the knee was flexed, and found that gluteus maximus EMG amplitude was reduced by a third when the hip was flexed, compared to when it was fully extended.

Injury to a growth plate can result in a misshapen or shortened limb which, in turn, can create an incorrect angle to a joint which can make the puppy more prone to yet more injuries when he grows up.

The different angle of the bones when pressure is applied causes joint stress and can lead to joint pain and arthritis.
