Fast vs Slow How good are you?
SLOW Fibers = Endurance FAST Fibers = Expolsive
Meat 1. Light meat versus dark meat?
Contractions 2. Powerful contractions versus steady contractions.
Respiration 3. Anaerobic versus Aerobic
Mitochondria 4. Lots versus little.
Fluid 5. Less blood supply versus highly vascular.
Energy 6. Use Glycogen versus use fat.
Review SLOW –Dark meat –Endurance –Steady –Aerobic –Lots of mito. –More vascular –Use Fat FAST –White meat –Explosive –Powerful Burts –Anaerobic –Little Mito. –Less Blood –Use Glycogen
ANAEROBIC Bursts of intense contractions (Hypertrophy) Fatigue easily *Train by increasing intensity, decreasing reps.
Aerobic Anaerobic threshold: If muscle demands stay below supply needs, will stay aerobic. If increased need, shift to anaerobic. *Train increase reps, decrease intensity.
Fast Slow and Intermediate Fibers Power: Maximum amount of tension that can be produced by a muscle Depends on number of contractile units which depends.
Section Athletes who excel in a particular sport stay fit by exercising their muscles. 2. Muscles that are not used or are used only for weak.
Sprinting is based on muscle strength Long distance running requires endurance Strength is the ability to do something that uses a lot of energy for a.
Slow and Fast twitch Muscle Fibre types Topic 4. Types of Muscle Fibers: A.Slow Twitch: (type 1) *smaller in diameter *reddish color *use aerobic respiration.
