•
Train reciprocating muscle groups
•
Balance
Time
• Allow body to adapt
•
6 to 8 weeks
• increase slowly
• rest between sets or alternate upper and lower body
We Are, What We Are!!!

This May Not Be Your Genetic

The Principles of Exercise
Apply to everyone but Individual EFFECTS will VARY
LIMITATIONS
TO Training
Aerobic Activity
Strength + Endurance
Flexibility
Anaerobic Training
Fitness Equipment / Safety
• Buy Appropriate SHOES
• Wear Comfortable Clothing
• TOO HOT! TOO COLD!
• Run and Walk with a Friend
More fun, safer, support system
• Night Time: stay to the well lit areas
• Seek Expert Fitness
Advice…….
Keep Your Plan Manageable,
Flexible,Varied and Fun
• Start at a level suited for you
• ask for help from an exercise professional
• It’s OK to miss a session
• Mirrors and Scales
• Rest when you’re tired
• Plan for the rest of your life
• Eat ( Good or Bad Food) moderation, balance and personal taste
Getting Started
Goals
• with a specific goal in mind design a program with a certified exercise expert!
Type of Program: endurance vs. Strength or a combination
Consider ergometers:
• stair climbers, bikes, rowers for endurance
Muscles
• Contract - All or
Nothing
•
Work Reciprocally
•
Adapt to Stress
•
Strength, Endurance,
Posture
•
Smooth - Involuntary
– blood vessels / digestive
• Skeletal - Voluntary
– biceps / triceps
•
Cardiac - spontaneous
– heart
Improving Muscular Strength and Endurance
• Muscular Strength:
The amount of force that a muscle is capable of exerting
• One Repetition Maximum
(1RM)
• Muscular Endurance:
A muscle’s ability to exert force repeatedly
Principles of Strength
Development
• Tension Principle:
– muscular tension
– the strength gain
– ……. Weight lifting is one method……..
– Weight machines (pulleys & cables), riding a bike up a hill
– all methods work
Resistance Exercise Program
•
Part of a FITNESS
Program to improve muscular strength and endurance
• Goal -
HYPERTROPHY
Muscle Action
• ISOMETRIC M.A.
•
Force without movement
•
ISOTONIC M.A.
•
Force with movement
•
Concentric M. A.
•
Eccentric M. A.
•
Best Results a
Combination…….
ISOKINETIC M.A.
• The Rate of M.A. is predetermined
•
60 0 / S, 90 0 /S, 180 0 / S
•
Degrees per Second
•
Force does not change the rate
•
Cybex Rehabilitation
Machine - very expensive, specialized,
• therapeutic uses
Methods of Providing Resistance
•
Body Weight Resistance: sit-ups, push -ups, pull - ups
(both concentric and eccentric m.a.)
•
Fixed Resistance: constant absolute resistance
(barbells and dumbbells)
Biomechanics - joint angles and applied force
Methods of Providing Resistance
•
Variable Resistance:
•
Nautilus
Distributes the load to to the muscles so that at each angle the load (weight) lifted is altered
•
Accommodation:
Resistance changes in response to the force - speed is kept constant
Be Kind to Your Muscles
Warm-up: Activity Readiness
•
Increase body temperature, heart rate metabolic pathways, etc.
• improves muscle performance
• specific appropriate stretching
Cardiovascular Conditioning
•
Frequency/ Intensity / Type/ Time
Strength Training / Endurance Training
Progressive, specific & appropriate
Cool Down + Flexibility
Your Active Life Plan
•
Are you ready to start a program?
• Health, Injuries, Attitude, reasons to exercises
• Select activities that you like to do.
• Walking, swimming, running, step class, aerobic, skating, skiing, cycling rowing…………etc,etc..
• Resistance Training
• Weight Training / Body as Resistance
• sit-ups, push-ups, free weights and wt.
Machines…..they all work
• Include:
•
Warm-up / stretching aerobic conditioning, strength/endurance training and flexibility improvements
Be Realistic and Honest with
Yourself
