Soreness can theoretically be avoided by limiting exercise to concentric and isometric contractions.
2.
During isometric contractions the series elastic component is under tension and therefore is stretched a finite amount.
3.
This is tested by determining the recruitment threshold of a motor unit during isometric contraction in which the force is gradually increased.
4.
The patient's restricted muscle is put in a position of stretch followed by an isometric contraction of the restricted muscle.
5.
Pushing is an active process that, assuming the wall does not move, produces an isometric contraction in muscles doing the pushing.
6.
The knee extensors of healthy old adults fatigue less during isometric contractions than do those of young adults who had similar levels of habitual physical activity.
7.
The mechanisms controlling fatigue in the elderly during isometric contractions are not the same as those that influence fatigue during dynamic contractions, while young adults keep the same strategy.
8.
Similarly, Akima et al . were able to maintain isometric peak torque in subjects who performed daily maximal isometric contractions of the knee extensors during 20 days of bed rest.
9.
At this rope length the skier's body is experiencing intense isometric contractions and extreme upper body torque with loads of up to 600 kg as they begin accelerating after rounding a turn buoy.
10.
Most isometric contractions in PNF stretching techniques should be held for a minimum of 3 seconds at a sub maximal effort ( 20-50 % of maximal effort ) to avoid muscle fatigue and injury.
