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
