During the process of muscle contraction, tension starts to build up within the tissue that leads for the body to create some sort of action or sometimes it doesnâ??t. Muscle contraction creates a movement whether it is voluntary or involuntary itâ??s the muscle contraction that is responsible for that certain action.
The chemical changes during muscular contractions include conversion of ATP into ADP, break-down of phosphocreatine and muscle glycogen, formation of Fructose diphosphate and lactic acid and resynthesis of creatine phosphate.
The nervous system is what will initiate contractions as well as determine the strength of a contraction.

Alpine skiing primarily involves isometric and concentric muscular contractions. Isometric contractions stabilize the body and maintain posture while navigating turns, allowing skiers to hold their stance against the forces of gravity and friction. Concentric contractions are used during movements like pushing off or accelerating, enabling skiers to generate power as they carve through the snow. Eccentric contractions also play a role, especially when absorbing shocks and controlling speed during descents.

Muscular contractions.
there are muscular contractions in the oesophagus which help to move the food this rhythmic movement is known as PERISTALSIS
The muscular contractions move the food, mix it with digestive juices, and bring the digesting food in contact with the mucosa where absorption takes place.
The muscular, nervous, and endocrine systems all control contractions in the uterus.
