Because playing football requires a variety of movements, including running forward and backward, twisting, raising and lower the arms, grasping and pushing, all of the major muscle groups are used. The major muscle groups include the abdominals, biceps, deltoids, erector spinae, gastrocnemius, soleus, gluteus, hamstrings, latissimus dorsi, rhomboids, obliques, pectoralis, quadriceps, trapezius and triceps.
The major muscles of the lower body are the quadriceps, hamstrings, gastrocnemius, soleus and gluteus. They are all used to run, stop, jump, move sideways and push off. The quadriceps and hamstrings form the upper leg, while the gastrocnemius and soleus form the bulk of the lower leg. The gluteus forms the buttocks.
The major muscles of the torso are the pectoralis, latissimus dorsi, rhomboids, deltoids, erector spinae, trapezius, abdominals and obliques. They allow the body to bend, twist and stand erect. They also assist in moving the arms up, down, forward and backward. The biceps and triceps form the upper arm and control flexion and extension.
The major muscle groups are supported and assisted by numerous smaller muscles and muscle groups that enable precise movements and actions such as keeping the head stable. Also, a number of auxiliary muscles control involuntary functions like inhaling and exhaling.
