Lifetime fitness ch 4

  1. 1. BUILDING MUSCLE Chapter 4
  2. 2. OBJECTIVES • List and define principles of resistance training • List benefits of resistance training • Define 3 types of training • List pros and cons of two major methods • Describe phases of training • List 5 pillars of a workout • Identify major muscle groups • Define "ergogenic aid"
  3. 3. BUILDING MUSCLE •Resistance training is the only type of exercise capable of slowing and maybe reversing loss of muscle mass, bone density, and strength •The “Use it or lose it” axiom applies to the 600-plus muscles in the body •Declining stimulation of the muscles results in progressive shrinking and weakening of the muscles (atrophy)
  4. 4. BENEFITS OF RESISTANCE TRAINING •Strength training increases muscle mass and decreases fat •Increased muscle mass means your body burns more calories – even at rest •The functions of daily life can be performed with less effort •Joint mobility improved •Arthritic symptoms reduced or eliminated •Stronger legs improve balance and reduce the risk of falling
  5. 5. BENEFITS OF RESISTANCE TRAINING (2) •Risk of osteoporosis is reduced •People can live independently and with dignity longer •Most disability associated with aging is due to disuse •Reaction time/skills improved •Healthier sleep patterns •Improves self-esteem, self-confidence, and body image •Positive impact on cardiorespiratory endurance, hypertension, blood fat levels and improves insulin control
  6. 6. PRINCIPLES OF RESISTANCE TRAINING • Intensity • Duration • Frequency • Overload • Progression • Specificity • Variety
  7. 7. TYPES OF CONTRACTIONS •Isometric- muscle doesn't change length •Isotonic- muscle shortens and lengthens against external force •Concentric- shortens •Eccentric - lengthens •Isokinetic - contraction against same resistance thru ROM
  8. 8. RESISTANCE TRAINING •Most resistance training is isotonic or isometric •Isokinetic is typical with rehab protocols
  9. 9. Muscular Strength - the maximum force a muscle or muscle group can exert Muscular endurance - the repeated application of muscular force against a submaximal resistance (HYPERTROPHY) Muscular power- the max amount you can lift in the shortest amout of time
  10. 10. MACHINES Pros - safe, easy to use, spotting not necessary Cons - expensive, space, mechanically flawed
  11. 11. FREE WEIGHTS Pros - versatile, stabilization, enhanced results Cons - it is a skill, increased risk of injury
  12. 12. TOOLS • Sandbags • Sand bells • Heavy ropes • TRX • Bodyweight • Dumbbells • Barbells • Kettlebells • Bulgarian Bags
  13. 13. PHASES OF TRAINING • Macrocycle - a year • Mesocycle - 8-12 weeks • Microcycles - 1-2 weeks
  14. 14. PILLARS OF TRAINING •Lower Body Push •Lower Body Pull •Upper Body Push •Upper Body Pull •Stabilization
  15. 15. BASIC ANATOMY
  16. 16. ERGOGENIC AIDS • Ergogenic aids are substances, techniques, and treatments that theoretically improve physical performance in addition to the effects of normal training • Some of the more well-known aids include: • Protein supplements • Creatine • Ginseng • Chromium Picolinate • Ubiquinone (Co-Q10) • Conjugated Lineoeic Acid (CLA) • Androstenedione (Andro) • Human Growth Hormone (hGH) • Anabolic-androgenic steroids
