  2. Lower-limb walking pattern - Wikipedia

    en.wikipedia.org/wiki/Lower-limb_walking_pattern

    The lower limbs are only in contact with the ground during the stance phase, which is typically subdivided into 5 events: heel contact, foot flat, mid-stance, heel off, and toe off. The majority of stance phase (~40%) takes place in single-limb support where one limb is in contact with the ground and the contralateral limb is in swing phase.

    What Are the Concentric and Eccentric Phases. Every exercise (squat, deadlift, bench press, curl, row, etc.) is comprised of two distinct phases: Concentric and eccentric. The concentric phase is ...

  4. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    Depiction of smooth muscle contraction. Muscle contraction is the activation of tension-generating sites within muscle cells. [1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. [1]

  5. Calf raises - Wikipedia

    en.wikipedia.org/wiki/Calf_raises

    Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).

  7. Plyometrics - Wikipedia

    en.wikipedia.org/wiki/Plyometrics

    As the legs are used singly, and perform the same amount of work, the body and legs may be strengthened more evenly than bilateral plyometrics, which may involve one leg doing an excessively large amount of the work. Some forms of unilateral plyometrics involve a cyclic alternation between the legs e.g. repeatedly jumping from one foot to the ...

  8. Leg extension - Wikipedia

    en.wikipedia.org/wiki/Leg_extension

    The leg extension is a good exercise for isolating muscular contraction in the quadriceps, [14] but as with all isolation exercises, should be included in a holistic resistance training program working all muscles, especially antagonistic muscle pairs (such as the quadriceps, hamstrings, and gluteal muscles), to avoid muscular imbalances, which ...

  9. Tibialis anterior muscle - Wikipedia

    en.wikipedia.org/wiki/Tibialis_anterior_muscle

    The tibialis anterior aids in any activity that requires moving the leg or keeping the leg vertical. It functions to stabilize the ankle as the foot hits the ground during the contact phase of walking (eccentric contraction) and acts later to pull the foot clear of the ground during the swing phase (concentric contraction). It also functions to ...
