Chapter 1 : Introduction



Introduction arrow_upward


  • Strength anatomy is the use of resistance to muscular contraction to build the strength, anaerobic endurance, and size of skeletal muscles.
  • It provides significant functional benefits and improvement in overall health.
  • There are many different methods of strength anatomy.
    • The most common being the use of gravity or elastic/hydraulic forces to oppose muscle contraction.
  • Technique used to target specific muscle groups include:
    • Incremental increases of weight.
    • Elastic tension or other resistance.
    • A variety of exercises.
    • Types of equipment.
  • It differs from:
    • Bodybuilding
    • Weightlifting
    • Powerlifting
  • Strength anatomy used in sports: football, rugby, lacrosse, basketball, hockey, and track and field.

  • Skeletal Structure arrow_upward


  • Skeletal structure frames the overall shape of the body and does not alter much over a lifetime.
  • Males are generally taller, but body shape may be analyzed after normalizing with respect to height.
  • Broad shoulders and expanded chest (in males).
    • Males generally have broad shoulders and expanded chests, allowing them to inhale more air to supply their muscles with oxygen.
    • Widening of the shoulders occurs as part of the male pubertal process.

    Overweight and Underweight arrow_upward


  • Being overweight or underweight causes change in the human body's shape as well as posture and walking style.
  • The fats and carbohydrates in food constitute the majority of energy used by the body.
  • Proteins mostly aid the growth and repair of tissues and muscles and have comparatively little effect on weight.

  • Types of Fat arrow_upward


  • We have adipose tissue all over the body. This tissue is made of adipocytes (fat cells) whose sole job is to store energy in the form of fat.
  • Body fat distribution differs from person to person.
  • Types of fat storage:
    • Visceral (surrounding organs).
    • Subcutaneous (beneath the skin - about 80% of all body fat).

    Fat distribution in Men and Women arrow_upward


  • Body shape is affected by body fat distribution, which is correlated to current levels of sex hormones.
  • Muscles and fat distribution may change from time to time, unlike bone structure, depending on food habits, exercises and hormone levels.
  • Fat distribution in Women:
    • Basic areas - generally around the buttocks and thighs (gluteofemoral): "pear-shaped".
    • Estrogen causes fat to be stored in the buttocks, thighs, and hips in women.
  • Fat Distribution in Men:
    • Basic area - generally around the abdomen: "apple-shaped".
    • Males have less subcutaneous fat in their faces due to the effects of testosterone; testosterone also reduces fat by aiding fat metabolism.

    Muscles arrow_upward


  • Testosterone helps build and maintain muscles through exercise.
  • Males have around 20 times more testosterone than females.
  • Prominent muscles of the body include:
    • The pectoral muscles.
    • Biceps and triceps in the arms.
    • Quadriceps in the thighs.

    Gaining Fat in Specific Areas arrow_upward



    Knee

  • Fat often builds up on the inside region of the knees in women.
  • Upper Arm

  • Fat build up can occur in the middle to upper area of the upper arm - typically covering the triceps area.
  • Common in women.
  • Abdomen

  • Fat buildup around the navel area.
  • Common in both men and women.
  • Inner Thigh

  • Fat storage between the thighs.
  • Common in women - but also occurs with men.
  • Outer Thigh

  • Sometimes called "Riding Breeches" - this area is the most likely place for the pitted or 'quilted' appearance of cellulite.
  • Buttocks

  • Without fat here sitting would be quite uncomfortable.
  • If significant fat is lost from the buttock, then only appropriate training can prevent the buttock from sagging down against the thigh.
  • Chest

  • Breast tissue comprises the mammary gland (one's 'endowment') surrounded by fat.
  • Men also have atrophied glands and fat in this area.
  • Both sexes gain fat in this area.
  • In men this can sometimes be mistaken for the condition of gynecomastia - a condition that includes not only fat build up, but growth in gland tissue.
