Sentences with phrase «increase erector spinae muscle»

During the squat, training with higher loads and faster speeds appear to increase erector spinae muscle activity, while internal cues, unstable surfaces, using both barbells and elastic resistance, altering footwear, and using a weightlifting belt do not affect erector spinae muscle activity.

Both very stable and very instable conditions increase erector spinae muscle activity.

Heavier loads, faster bar speeds, and greater depth (with the same relative load), all lead to increased erector spinae muscle activity during back squats.

Assessing the effect of bar velocity, Manabe et al. (2007) found that performing the back squat with quicker speeds with the same relative load increased erector spinae muscle activity when compared to slower speeds.

Not exact matches

At the end of the research, it was found out that there was increased muscle activation in the thoracic erector spinae.

Studies have shown that using a weight belt either has little effect at all on the erector spinae muscles (lower back muscles) or an increase of their engagement by up to 25 %.

They noted that erector spinae muscle activity at the time of lift off was 62 % and that erector spinae muscle activity increased from lift - off to knee passage, where it was 84 %.

Therefore, it appears that the lower erector spinae muscle activity is relatively high regardless of load, while thoracic erector spinae muscle activity displays a larger increase between loads < 60 % and loads of > 80 % of 1RM.

Lumbar erector spinae muscle activity appeared to increase with increasing load, between 50 — 60 % of 1RM.

In contrast, in the descending phase, both upper and lower erector spinae muscle activity grew higher as the knee angle increased from the top portion of the lift (0 — 30 degrees knee flexion) to the bottom portion (61 — 90 degrees knee flexion).
