Strength Training 1 & 2 Final Review

What is Strength?

Muscular Strength: ability of a muscle or group of muscles to generate force • Absolute strength: maximal amount of force that can be

generated during 1 maximal effort.• Dynamic strength: ability of a muscle to contract

repeatedly over a period of time.

Muscular Endurance: ability to contract muscles many times without tiring or to hold one contraction for a long time

Elements of Muscular Fitness

Strength: ability to exert forceEndurance: ability to continue work over an extended period of time (Cardiovascular endurance is most important, why?)

Flexibility: ability to move easily through complete normal ranges of motion around a joint

What is Muscle?

• Made up of 75% water and 25% protein.

3 types of muscle:1.) Smooth: walls of internal organs, stomach and blood vessels2.) Cardiac: heart3.) Skeletal: attach to bones making movement possible

Roles Muscles Play

• Agonist: Prime mover, muscle primarily responsible to produce movement.• Antagonist: Muscle in opposition to the agonist.• Stabilizers: Hold the joint steady while other muscles produce

movement. Aid in the contraction.• Neutralizers: Muscles that contract to prevent unwanted action.

Bench PressAgonist: Pecs, TricepsAntagonist: LatsStabilizers: Anterior DeltoidsNeutralizers: Forearms

Types of Muscle Contractions

Isometric (static)

- No movement occurs at the joint although force is generated

Isotonic (dynamic)

General Training Principles

• The Principle of Overload: the body will function better if increased demands are placed upon it

F= Frequency

I= Intensity

T= Time

General Training Principles

• The principle of progression: Allows you to increase your workload when your body adapts to the current load.• The principle of specificity: Occurs when specific exercises

are done that closely resemble the specific activities performed.

General Training Terms

•Repetitions (reps) – the number of consecutive times you do an exercise•Set – one group of repetitions•Hypertrophy – increase in muscle size•Atrophy – decrease in muscle size•Resistance – a force that acts against

your muscles •1 rep max (1RM) – amount of weight

lifted one time•Plyometrics- develops power with

explosive movements

10 Principles of Resistance Exercise

1.) Warm-up: Light running, light lifting, dynamic stretching to help improve blood flow and flexibility, & to reduce chance of injury.

2.) Exercise Range of Motion: To strengthen entire muscle, complete exercise through fullest possible range of motion that the joint allows. Muscle is conditioned through its entire length.

3.) Exercise Speed: It should take approx. 1 sec. to complete every 90 degrees of joint motion.

4.) Breathing: Exhale during concentric phase (POSITIVE PHASE) of exercise. Inhale during eccentric phase (NEGATIVE PHASE). Ex. Bench Press: Exhale to push, Inhale to bring bar back down. Why we breathe

10 Principles of Resistance Exercise 5.) Recommended # of Repetitions: Strength: more weight less reps (3-5 reps per exercise – 80%-90% of

MAX) Endurance: Less weight more reps (13-25 reps per exercise – 50%-60% of

MAX)Combination: benefits in strength and endurance (6-12 reps per exercise

– 65%-75% of MAX)Pyramid System: decrease reps while increase weight

6.) Rest Between Sets: 60 to 90 seconds of rest, may vary w/ the individual and/or exercise intensity.

7.) Rest Between Repetitions: When applicable, a 1-2 second pause is recommended between each repetition.

10 Principles of Resistance Exercise8.) Recommended # of Sets: dependent upon the fitness level and

intensity. Generally, 1-3 sets of exercise are recommended per body part.

9.) Increasing Workload: The rule of thumb is to increase the weight load by 2-5% when progression is to take place. This normally occurs when the final repetitions of the last performed set are completed easily.

10.) Exercise Intensity: The goal is to achieve momentary muscle failure on each set. Momentary muscle failure refers to total fatigue or failure on the final predetermined repetition of each set.

Nutrition

• Carbohydrates (60% total kcal) are the body’s primary source of energy.Carbs Fat (stored energy) Protein

• Protein: repair and build muscle and all body systems

• When weight training, a general rule, 1 gram of protein per pound of body weight.
