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.
Most strokes involve rhythmic and coordinated movements of all major body parts — torso, arms, legs, hands, feet, and head. Breathing typically must be synchronized with the strokes, too. It is possible, however, to swim by moving only legs without arms or only arms without legs; such strokes may be used for special purposes, for training or ...
Your core muscles aren't just your abdominal muscles (the abs). The muscle group also includes the pelvic floor muscles, gluteal muscles (glutes), and the diaphragm. Find workouts here.
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.

A functional muscle synergy is defined as a pattern of co-activation of muscles recruited by a single neural command signal. [18] One muscle can be part of multiple muscle synergies, and one synergy can activate multiple muscles. Synergies are learned, rather than being hardwired, like motor programs, and are organized in a task-dependent manner.
