Presentation Objectives:
1. To discuss the foundations of weight training
2. To discuss general program planning considerations
3. To locate muscles and understand their functions
4. To develop specific weight training programs for specific
goals
FOUNDATIONS OF WEIGHT TRAINING
Weight Training Definitions
 The term weight training describes a type of exercise that
requires the body’s musculature to move (or attempt to move)
against an opposing force, usually presented by dome type of
equipment.
 The American Council on Exercise (ACE) defines weight training
as the process of exercising with progressively heavier
resistance for the purpose of strengthening the musculoskeletal
system.
 Weight training typically refers only to normal resistance training
using free weights or weight machines
FOUNDATIONS OF WEIGHT TRAINING
Weight Training Terminology
 REPETITION = one complete movement of an exercise. It
normally consists of two phases: the concentric muscle action
(lifting the resistance) and the eccentric muscle action (lowering
of the resistance).
 SET = a group of repetitions performed continuously without
stopping. Sets typically range from 1 to 15 repetitions.
 REPETITION MAXIMUM (RM) = the maximum number of
repetitions per set that can be performed at a given resistance
with proper lifting technique
FOUNDATIONS OF WEIGHT TRAINING
Weight Training Terminology
 POWER = rate of performing work. Power during a repetition is
defined as the weight lifted times the vertical distance the weight
is lifted divided by the time to complete the repetition. You can
increase power by decreasing the time to complete the
repetition or by increasing the weight lifted.
 STRENGTH = the maximal amount of force a muscle or muscle
group can generate in a specified movement pattern at a
specified velocity of movement.
FOUNDATIONS OF WEIGHT TRAINING
Types of Strength Training
 ISOMETRICS = also known as static resistance training. Refers
to a muscular action during which no change in the length of the
muscle takes place. This type of resistance training is normally
performed against an immovable object such as a wall, a
barbell, or a weight machine loaded beyond an individual’s
maximal concentric strength.
 DYNAMIC CONSTANT EXTERNAL RESISTANCE TRAINING
Describes resistance training exercises in which the external
resistance or weight does not change and both a lifting
(concentric) and lowering (eccentric) phase occur during each
repetition. This type of exercise is normally performed with freeweights or various weight training machines.
FOUNDATIONS OF WEIGHT TRAINING
Types of Strength Training
 VARIABLE RESISTANCE TRAINING = equipment that
operates through a lever arm, cam, or pulley arrangement. This
type of equipment alters the resistance in an attempt to match
the increases and decreases in strength throughout the
exercise’s range of motion.
 ECCENTRIC TRAINING = also called negative resistance
training. Refers to a muscular action in which the muscle
lengthens in a controlled manner. Eccentric training can be
achieved by lowering resistances greater than 1 RM (freeweights or machines).
 PLYOMETRICS = more commonly known as stretch-shortening
cycle exercises. The muscle is slightly stretched and then
shortens.
FOUNDATIONS OF WEIGHT TRAINING
Benefits of Strength Training
 Increased muscle fiber size
 Increased muscle contractile strength
 Increased bone strength
 Reduced risk for injury
 Improved ability to perform work or exercise
 Improved body composition
 Increased metabolic rate
GENERAL PROGRAM PLANNING CONSIDERATIONS
Factors That Affect Strength Training
 GENDER. Although male and female muscle tissue is essentially
the same, men typically have more muscle than women because
the presence of testosterone positively influences muscle size.
 AGE. The rate of strength gains appears to be greater during the
years of normal growth and development, generally considered to
be from ages 10 to 20 years.
 MUSCLE LENGTH. People with relatively long muscles have a
greater potential for developing size and strength than people with
relatively short muscles.
 MUSCLE FIBER TYPE. People with a prevalence of fast-twitch
muscle fibers may obtain better results from their strength-training
program.
GENERAL PROGRAM PLANNING CONSIDERATIONS
Strength Training Protocol
 WARM-UP: a necessity for maximizing safety during strength
training workouts
 Should gradually increase the heart rate, blood pressure,
oxygen consumption, dilation of the blood vessels, elasticity of
the active muscles, and the heat produced by the active
muscle groups
 Should consist of graduated aerobic activity and flexibility
exercises specific to the biomechanical nature of the primary
conditioning activity
 The intensity of the warm-up should be well below that of the
primary conditioning activity
 Helps prepare the mind and body for the primary physical
activity.
GENERAL PROGRAM PLANNING CONSIDERATIONS
Strength Training Protocol
 PRIMARY STRENGTH TRAINING ACTIVITY: based on the
exerciser’s goals
 COOL-DOWN:
 Purpose is to slowly decrease the heart rate and overall
metabolism
 Activity used for cool-down should be low-level aerobic
exercise, similar to that of the conditioning exercise
 Helps prevent the sudden pooling of blood in the veins and
ensures adequate circulation to the skeletal muscles, heart,
and brain
 May aid in preventing delayed muscle soreness
 Reduces any tendency toward post-exercise fainting and
dizziness.
GENERAL PROGRAM PLANNING CONSIDERATIONS
Strength Training Resources
 VARIABLE RESISTANCE EQUIPMENT
 Advantages = safe, less balance required, productivity in a
short amount of time, less supervision required, and ideal for
circuit training
 Disadvantages = lack of development of balance and
coordination and constrained movement patterns
 FREE-WEIGHTS
 Advantages = balance required which results in better
coordination and greater muscle utilization, greater variability,
and exercises resemble real-life movements
 Disadvantages = requires strength to maintain balance and
coordination, accidents are more likely to happen, spotters are
required, complete workouts may take more time, and inability
to train through the entire range of motion
