Question

At the gym there is a machine called the abductor machine, which exercises the thigh muscles. How does the machine move your thighs to exercise them? -it lifts your thighs upward at an angle -it lifts your thighs downward -pushes both thighs outward separating your knees as far as possible -pushes both thighs inward bringing your knees together?

Answer 1

The gym's abductor machine moves your thighs by pushing both outward, separating the knees, which exercises the muscles responsible for thigh abduction, primarily the gluteus medius and minimus.

Step-by-step explanation:

The abductor machine at the gym targets the muscles that move the thigh away from the body's midline. When using the abductor machine, it pushes both thighs outward, separating your knees as far as possible. This motion engages the gluteus medius and gluteus minimus muscles, which are responsible for the abduction of the femur at the hip. It contrasts with adductor machines, which move the thighs inward, working muscles like the adductor longus, adductor brevis, and adductor magnus that adduct the femur.

Understanding how these machines and muscles function can enhance exercise efficiency and support balanced muscle development.

Answer 2

The abductor machine operates by pushing the user's thighs outward, working primarily the gluteus medius and gluteus minimus to abduct the femur at the hip.

Step-by-step explanation:

The abductor machine at the gym targets the thigh muscles by pushing both thighs outward, separating your knees as far apart as possible. This movement involves the abductor muscles of the thigh, primarily the gluteus medius and gluteus minimus muscles. These muscles are key in abducting the femur at the hip, which means to move it away from the body's midline. In contrast, the adductor muscles work to pull the thighs inward. The main adductor muscles include the adductor longus, adductor brevis, adductor magnus, and the gracilis.

When using the abductor machine, you are not lifting your thighs upward or downward, nor are you bringing your knees together, which would be an action of the adductor muscles and suited for a different machine, often referred to as the 'adductor machine.'
