Week 5
One consistent Research Finding
-Variety helps
-(12-14 weeks min)
-Every 4-6 weeks is ideal
Periodic action
-Resistance Training periodization (chapter 8)
Eccentric Loading
-Eccentric (negative) - goes down
-Isometric (static)
-Concentric (isotonic) - goes up
-Go slow at high intensities until you’re used to it because forces go high during eccentric
contractions
Delayed Onset Muscle Soreness (DOMS)
-High during at high eccentric intensities
Strength Training Misconceptions
-Women will bulk up and look unattractive
-Resistance training slows you down
-Marathon workouts (I haven’t got time to go to the gym for 2 hours)
-You become muscle bound
-Protein supplements are necessary for strength gains (only for serious Athletes)
-Muscle will convert to fat after I stop training
Avoiding Injury During Weig
Atrophy
-decrease in muscle fire size
Ergogenic AIDS
-To aid work
-Anabolic Steroids: Drugs that resemble androgen if hormones (testosterone)
-Anabolic: protein synthesizing effects
-Androgenic: male secondary sexual characteristics
-Allow you to work harder and recover quicker
Harmful effects of steroids
-Liver damage (jaundice, cancer)
-Coronary heart disease (increased blood pressure, increased serum lipids)
-Testicular atrophy
