Study Notes
Strength Training Concepts
- Strength defined as the maximal force exerted by an individual.
- Absolute strength measures force without considering body weight.
- Relative strength determined by dividing absolute strength by body weight.
Muscle Types
- Cardiac muscle makes up the heart, is striated, and contracts as a unit.
- Smooth muscle comprises the walls of blood vessels and organs; it is non-striated and usually not under voluntary control.
- Skeletal muscle is under voluntary control and facilitates body movement, developed through strength training.
Muscle Fiber Types
- Fast-twitch fibers generate high force but fatigue quickly.
- Slow-twitch fibers produce lower force but resist fatigue effectively.
Muscle Contraction Types
- Isometric contractions occur without change in muscle length.
- Isotonic contractions involve a change in muscle length during contraction.
- Concentric contractions characterize muscle shortening (e.g. lifting a dumbbell).
- Eccentric contractions involve lengthening of the muscle (e.g. lowering a dumbbell).
- Isokinetic contractions exert maximal force through a full range of motion.
Energy Systems
- ATP serves as the energy source for muscle movement, composed of an adenosine group and three phosphates.
- The Phosphagen System supports short, high-intensity activities, relying on stored ATP for 6-10 seconds.
- Examples of the Phosphagen System include a 40-yard dash and vertical jump.
- The Lactic Acid System breaks down carbohydrates for ATP, functioning effectively for 2-3 minutes.
- Activities under the Lactic Acid System include sprints and running uphill.
- The Oxidative System utilizes oxygen to metabolize carbohydrates and fats for ATP, typically involved in low-intensity aerobic exercise.
Training Goals
- Hypertrophy aims for muscle growth through 3-5 sets of 8-12 reps.
- Strength training focuses on increasing muscle strength using 3-5 sets.
- Endurance training aims for sustained activity, requiring 3+ sets and 12+ reps.
Training Principles
- Stimulating training sufficiently promotes adaptation.
- Retaining training maintains fitness without improvement.
- Detraining occurs when training intensity is insufficient, leading to strength and muscle loss.
- Progressive overload necessitates regular increases in training demands for performance enhancement.
Training Variables
- Volume refers to the total quantity of work done, expressed as sets and reps.
- Intensity is the quality of work, including weight lifted, speed, or percentage of maximum capability.
- Exercise order typically follows: total body lifts (power), multi-joint exercises (bench press, squat), and single-joint exercises (leg curls, pull-ups).
Equipment Facts
- A standard barbell weighs 45 lbs.
- An alternate grip is used for spotting during bench presses.
- Safety pins are recommended for use during squats to enhance safety.
