Hip Flexors: Trailing leg Calf Muscles: Leading leg

1) Hip flexor muscles are located on the trailing leg.
2) Calf muscles are located on the leading leg.
3) Hip flexor muscles are located on the leading leg.
4) Calf muscles are located on the trailing leg.

Answer 1

Hip flexor muscles are on the anterior side of the pelvic girdle, and they are engaged in the trailing leg during movements like lunges. The calf muscles, including the gastrocnemius and soleus, are in the posterior compartment of the leg and active in the leading leg during these movements.

Step-by-step explanation:

The question is regarding the location of the hip flexor muscles and the calf muscles during a movement in which there is a leading and a trailing leg, such as a stride or lunge. The hip flexor muscles, which include muscles like the adductor longus and the pectineus, are primarily located in the anterior region of the pelvic girdle and help in flexing the thigh. When a leg is described as trailing, it means it is behind the body during the motion, and thus the hip flexors of the trailing leg are engaged to pull the thigh and knee upwards. The calf muscles, which include the gastrocnemius and soleus, are located in the posterior compartment of the leg and are responsible for plantar flexion, meaning they help push the foot down, which occurs in the leading leg during such movements.
