Essay about Squat Physiology - a Brief Discussion

In this phase the athlete is standing in a neutral position holding the ball. The metatarsophalangeal and interphalangeal (great and lesser toes) are held at slight flexion pressed against the ground by an isometric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The ankle is plantar flexed using an isometric contraction of the gastrocnemius and the soleus. The tibiofermoral (knee) joints are slightly flexed by a isomectric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The acetabularfemoral (hip) joint is held at a postion of slight flexion through an isometric contraction of the biceps femoris, pectineus, iliacus, and the psoas. The intervertebral (lumbar) joint is extended by an isometric contraction using the erector spinae. The atlantooccipital (cervical spine) joint is flexed by an isometric contraction erector spinae. Both scapulothroracic (shoulder girdle) joint is protracted by an isometric contraction of the serratus anterior and pectoralis minor. The glenohumeral (shoulder) joint is at internal rotation by an isometric contraction using the pectoralis major, latissimus dorsi, teres major, and the subscapularius. The humeroulnar (elbow) joint is at 90 degrees of flexion by an isometric contraction using the biceps brachii, brachioradialis, and brachialis. The radiocarpal (wrist left and right)

Many people are under the assumption that kinesiology was introduced to the world in the more recent years. They tend to date its beginnings to when it became the science and subject matter we have come to know today and was introduced in our school systems as a potential degree to major in. Through research and digging into the world’s history I have found the origins of kinesiology to date back as far as 384 B.C. In this paper I will be uncovering the roots of the science we are familiar with today and introduce you to the key players who contributed to the science and fundamentals that encompass this incredible area of study.

Participants in this study were healthy men and women ages 18-24. There were several criterions the participants had to meet before partaking in the study. Each individual had to successfully barbell back squat their own body weight for 1 repetition. Also participants were constantly observed by strength and conditioning coaches to ensure proper technique was applied to the barbell back squat. Lastly participants must have previously

Bonnechere and all’s purpose of writing this article was to “ [share] a biomechanical analysis of three different sprint start patterns to

Shoulder flexion/extension; Elbow flexion and extension; Use of the lower and upper back. Muscles involved include the latissimus dorsi, rhomboids, trapezius, deltoids and the pectorals.

The key muscles that contract when executing an inversion are the tibialis posterior and tibialis anterior. The muscles that are required to perform a successful eversion are the fibularis brevis and fibularis longus. The next movement is dorsiflextion, which requires the flexion of tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles. Lastly, the motion of plantar flexion demands the contraction of the gastrocnemius, plantaris soleus, and the fibularis longus. Since the ligaments are weak, the surrounding muscles must be stronger in order to stabilize those ligaments or those ligaments might become very fragile and

A different type of work out is if you are not the best person at doing squats or fall while you trying to do them what you can do is put the ball behind you and use it as a support or back up for if you were to fall and struggle you have a safe cushioning to fall back on(note this is a ball and can move is done unyielding).one more example is the ball pass where you lay down and pass the ball from above your head to your feet

These exercises build strength and endurance in your knee. Endurance is the ability to use your muscles for a long time, even after they get tired.

Tortora, G. J., & Nielsen, M. T. (2015). Principles of human anatomy (13th ed.). New York:

One example of an exercise using a combination of several of these movements together is jumping squats with free weights. This exercise targets the lower body, core and also the upper body. The quadriceps, the hamstrings, the gluteal, the lower back and the abdominals. The back muscle act as stabilizers to keep the body in a correct balance position. In the explosion phase, hip extends in a slight adduction knee extension and ankle plantar flexion. During the landing phase, back into the squat position, all the muscle is in an eccentric position, the hip flexion with slight abduction, knee flexion, and ankle dorsiflexion. Jumping squats with weights are just one of the extended workouts that utilize these principles. It is very important to understand the fundamental movements of major body segments in order to design and execute appropriate workout for my clients and their personal

The abdominal muscles play an important role with regards to stability of the lower back and associated structures, and therefore by gently working these while performing this exercise, you will be helping to provide your lower back and pelvis with more stability as well.

One of the primary neuromuscular strategies for knee stabilization is through simultaneouscontraction of the quadriceps- and hamstring musculature. At knee flexion angles greater than15 to 30 degrees, co-contraction of the hamstrings during quadriceps dominant activities is believed to counteract the anterior displacement of tibia, thus protecting the ACL (Draganich,Jaeger

They determined the intra and extra cellular compartments using a bioimpedance spectroscopy and determined the muscle contracting and shortening at a consistent rate of speed during a squat using a isokinetic dynamometer. They took these measurements before, after the training period, and after the detraining period. They found that there was an increase of 6% in both the placebo and creatine group. Which constitutes that creatine did not have any benefits regarding the force measured during a single movement. There was no change in body mass in the placebo or controlled group. However, there was an increase by 2 kg in body mass in the creatine group. This change can be due to partially the body water content and an increase in inter-cellular

This website was developed by James Griffing, he has a master’s in Kinesiology and a bachelors in exercise science. With contributions from many professionals such as, Eric Serrano, Lon Kilgore, Brent Rushall, Bryan Helwig, Joel Seedman, Joshua Seedman, Eladio Valdez III, and Marv Fremerman.

The quads include the rectus femoris, and the vastus lateralis, intermedius, and medialis. This muscle group shares a common tendon at insertion. The patellar tendon inserts at the tibial tuberosity, and within this tendon lies the patella. The patella is anterior to the femur-tibia articulation, and this sesmoid bone increases the leverage of the quads by acting as a pulley. The major contributor to the stability of the knee joint is the strength of the quads. The only muscle that assists in extension is the tensor fascia lata.
