FIRST NOTES ON ANATOMY AND PHYSIOLOGY FOR SOCCER
As with all athletic endeavors, an understanding of the roles played by human anatomy and physiology are critical to success in soccer. Anatomy is the identification of the structures, forms, and physical components of the body. Physiology is the understanding of the functions, processes, and interactions of the anatomy that allow the body to live and to react to its environment. The anatomy and physiology of the human body are entire areas of subject matter unto themselves. As coaches progress from the lowest levels of youth soccer to the highest levels of advanced (or even elite), soccer, they must immerse themselves in this subject matter in order to understand how human anatomy and physiology apply to the sport and to the age group involved. The following treatment represents areas to be pursued.
(Includes muscle conditioning, which could be considered to be part of physiology.)
Base components of the Human Body:
Skeletal system – bone, cartilage
Muscular system – grouped as legs, core (abdomen, back, hips, chest), shoulders, neck, and arms
Circulatory system – heart, veins, blood, waste removal
Respiratory system – trachea, lungs, oxygenation
Nervous system – brain, spinal cord, nerves, eyes
Digestive/Excretory system – mouth, esophagus, stomach, intestines
Connective tissue – tendons, ligaments
(It is extremely important to understand the structure of the knee and the foot.)
Fitness assessment of a player to measure future progress, including such things as height, body weight, body mass index, shape, proportion, age, gender, eyesight, respiration, resting heart rate (pulse), blood pressure, lung capacity, free weight displacement, reaction time, range of motion, and vertical jump.
Physical fitness for playing the sport of soccer.
Any part of the body used to receive the ball.
The overall strength and fitness of the abdomen and chest (torso, trunk) of the body.
Dominant foot, Dominant leg
A natural preference for one extremity over the other, such as being right-handed or left-handed.
A form of stretching utilizing the momentum from basic, well-controlled movement. (Caution: Dynamic stretching can be beneficial. However, when performed incorrectly, it may result in injury. Learn and use proper technique. “Do not bounce your stretches. Ballistic (bouncy) stretching can cause injury.” – American Academy of Orthopedic Surgeons) See: Why Stretch and Standing Stretches.
Sudden muscle use at the highest level in the shortest period of time.
A type of training, usually associated with goalkeepers, to promote quick and decisive actions.
The straightening out of a limb of the body at a joint due to muscle contraction.
Proper 20/20 binocular vision, natural or due to Lasik or contact lenses. See: Eyesight.

Pubescent Girls and Women ARE different
The angle of the legs in relationship to the hips, and differences in the structure of the knee require revised training methods for jumping and landing. Revised methods for strengthening the knee, in particular, are critical to the prevention of injury.
Range of motion
In a human being, a normal range of motion refers to the amount of movement that a particular joint or body part can move, as measured in degrees.
Form of strength training.
Right side of the body
That half of the human body, to the side of the midline, which does not contain most of the heart.
Increase in muscle mass, usually measured in the amount of weight that can be displaced.
Strengthening Exercises – Example: “Curls”
Exercises are designed to increase muscle mass and effectiveness. “Curls” use slow, deliberate flexion and extension through the full range of motion. Abdominal curls mainly work the abdominal muscles. Leg curls mainly work the hamstrings (and the calves). Arm curls mainly work the biceps. See: Basic Strengthening Exercises and Intermediate Strengthening Exercises.

A brief period of light exercise and/or stretching after a strenuous practice, designed to gradually decrease the heart rate and promote a return to a resting state.
Warm up, Warm-up, Warm-ups
(1) A period of gradually more challenging exercises designed to increase the heart rate and promote a level of activity appropriate for a strenuous practice or game. Usually includes stretching; (2) A systematized approach to ensure that appropriate exercises and stretching are performed to prepare the body for a practice or match.
