Chapter 6 – Training for Muscular Strength and Endurance
Learning Objectives
- Describe muscular structure and function
- Identify types of muscles
- Describe an effective resistance exercise program
- Assess your muscular strength and endurance
- Understand the dangers of supplements
- Muscles– organ in the body that causes movement
- Skeletal Muscle– Responsible for body movement
- Cardiac Muscle– Responsible for the contraction of the heart
- Muscle Fiber– individual muscle cell
- Motor unit– a nerve controlling a group of muscle fibers
- Myofibrils- threadlike structures running the length of the muscle fiber
- Insertion– point where the muscle is attached to a bone that moves
- Origin– point where the muscle is attached to a bone that remains in a fixed position
- Action Potential– the electrical current that cause a muscle to contract
- Sliding Filament Theory– the theory of how our muscles move
- Dynamic contraction– muscle movements that cause bodily movements
- Repetition– One movement pattern
- Set– a group of repetitions
- Periodization– Breaking resistance training into different training phases
- Strength– the maximal amount a force that can produced one time
- Hypertrophy– muscle fibers getting bigger
- Atrophy– muscle fibers getting smaller
- Isokinetic– muscle is contracted at a constant tempo
- Isometric– muscle contraction that causes no change in muscle length/no bodily movement
