根据They are your involuntary (不随意的) muscles,such as your heart muscle and smooth muscles.(它们是你的非随意肌,比如你的心肌和平滑肌。)可知D项属于非随意肌肉。故选D。(2)细节理解题。根据If the muscles around your knee,for example,get weak,you will more probably injure ...
Jumping exercises that involve pushing off from the ground horizontally are a great way to boost your sprint speed, strength, and power. These exercises work out all the essential muscle groups you need for sprinting, like your glutes, quads, hamstrings, calves, and core muscles. For example, ...
Slowly extend your arm afterwards until it is straight again. Repeat for the desired amount of reps before switching arms. Make sure that no body part other than your forearms are moving during the exercise — don’t squeeze with your knee to assist your arm. To increase the difficulty, si...

The problem lies in the hamstrings’ design; they’re much more complex than most other muscles. They cross two major joints—the hip and the knee—and shorten at both ends. At the top end, the hamstrings work with your glute muscles to extend your hip (picture the movement of standing ...
because the two muscles are responsible for hip flexion and adduction, as well as knee flexion in the case of gracilis, hip frontal and sagittal plane and knee sagittal plane kinematics were also investigated. It was hypothesized that the adductor muscles would show a higher activation during IP...
This balance happens through specific sensory receptors, known as proprioceptors, that live in joint capsules, muscles, tendons, and fascia. Think of these proprioceptors as the ball bearings of the body. They continually exchange motor and sensory signals information with your brain cells and pla...
