Major Muscles Involved in Jumping: Leg, feet and gluteus muscle groups are the major muscles used in jumping. Specific muscles which are involved in jumping are gluteus maximus, hamstrings, quadriceps and soleus. In fact, jumping occurs in three stages. The first stage is the preparatory stage where ankle muscles, calf muscles and soleus tense to prepare launching. The second phase is the launch phase, where hip extensors, the hamstrings and gluteus maximus combine and the knee extensors extend the knees to allow the body to launch into the air. The last stage is the landing phase where all the muscles embrace impact and allow the body to return to a resting position. Core muscles also play a vital role in jumping. However, the muscles of the arms also help in jumping farther.
