Between stimulus and response, there is a space.

In that space lies our freedom and our power to choose our response.

In our response lies our growth and our happiness.

– Viktor E. Frankl –

Handball is a game in which the movements performed by a player are very diverse, but it is predominantly a unilateral sport in which some movements are repeated much more than others (passing the ball and shooting if we observe the arms and torso, and stopping the maximum speed and changing direction if we observe the legs and torso) and is therefore ideal for creating imbalances in the body. 

Since the right hand is dominant for most players,

the left foot is used as a foothold for most movements.

Jump shots, landings, changes in the direction of movement, penetration and feints make up the largest part of the movement in the attack, and in defensive actions defenders most often use the left diagonal position because they most often stop right-handers. 

All of the above movements begin by stopping the body.

As this stopping is generally performed unilaterally on the left leg and the knee does not have the freedom of movement of rotation around the transverse axis, in order for the body to remain stable rotation in the ankle and internal rotation of the hip must be prevented.

Effective stopping requires the body to adapt to the ability to create large forces in the shortest possible time. With a long process of strengthening the muscles and shortening the tendons, the body becomes more efficient in shortening the movement of the internal hip rotation.

However, excessive use creates a physical imbalance that leads to an increased susceptibility of injuries, syndromes and impingement to the left hip.
