The goals of performing these exercises were to reduce pain and provide lower trunk stability by actively developing the "abdominal, gluteus maximus, and hamstring muscles as well as..." passively stretching the hip flexors and lower back (sacrospinalis) muscles. Williams said: "The exercises outlined will accomplish a proper balance between ...
Lie on back with arms on mat and hands under butt, palms down, legs raised at a 90-degree angle from the floor, feet flexed. Slowly lower one leg as far down as possible without back lifting off ...
The barbell back squat Bodyweight squat. A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent, the hip and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up.
Muscle activation is significantly different depending on whether the pull-up is completed individually or in a set without resting between repetitions, which is more efficient due to muscle and tendon stretch-shortening rebound. [8] Overhead movements such as pull-ups reduce the subacromial space and create a risk of shoulder impingement ...
Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).
When a joint is passively flexed, the resisting force comes from the stretch reflex (or sometimes called tendon reflex) resulting from the extensor muscle being stretched. [1] In upper motor neuron lesions , muscle tonus may increase and resistance of muscle to stretch increases.
This pause may last for seconds to several minutes, during which time there is spasming of the muscles of the hind limb and tail, leading to trembling ("shivers"). [2] Similar signs may be seen when the horse is asked to simply lift a hind foot, or during farriery work, especially when the foot is hammered during shoeing. Horses may progress to ...
