The flutter kick in a front crawl. In swimming strokes such as the front crawl or backstroke, the primary purpose of the flutter kick in beginner and intermediate swimmers is not propulsion but keeping the legs up and in the shadow for the upper body and assisting body rotation for arm strokes.
Backstroke swimming (amateur competition, non-optimal style) In backstroke, the arms contribute most of the forward movement. The arm stroke consists of two main parts: the power phase (consisting of three separate parts) and the recovery. [3] The arms alternate so that one arm is always underwater while the other arm is recovering.
In high school, collegiate, and Olympic swimming, there are two undulating strokes (breaststroke and butterfly stroke) and two alternating strokes (front crawl and backstroke). Most strokes involve rhythmic and coordinated movements of all major body parts — torso, arms, legs, hands, feet, and head.
The septa are formed from the fascia which is made up of a strong type of connective tissue. The fascia also separates the skeletal muscles from the subcutaneous tissue. [2] Due to the great pressure placed on the leg, from the column of blood from the heart to the feet, the fascia is very thick in order to support the leg muscles. [3]
Pronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three cardinal plane components: subtalar eversion, ankle dorsiflexion, and forefoot abduction, [1] [2] these three distinct motions of the foot occur simultaneously during the pronation phase. [3]
Along with the soleus muscle, the gastrocnemius forms half of the calf muscle. Its function is plantar flexing the foot at the ankle joint and flexing the leg at the knee joint. The gastrocnemius is primarily involved in running, jumping and other "fast" movements of leg, and to a lesser degree in walking and standing.

This may protect the ankle joints and lower limbs from some of the impact-related injuries experienced by rear-foot strikers. [ 8 ] In a 2017 article called "Foot Strike Pattern in Children During Shod-Unshod Running", over 700 children aged 6 to 16 were observed using multiple video recording devices in order to study their foot strike ...
