• What our muscles do for us
• What are the benefits of RT
• What are the risks
• Recommendations and Guidelines
• Samples
Help us move (Produce ALL voluntary movement)
What do our muscles do for us?
Maintain posture
Stabilize our joints
Generate Body Heat
WHAT DO OUR MUSCLES DO FOR
US?
Why are muscles so important?
Critical to Joint health, less stress
Posture and Symmetry. Less Stress on Connective tissue
Ability to perform ADL and keep independence
Diabetes and insulin sensitivity every 72hrs. Mod-Vig more
effective Helps with fat loss and metabolism. Upgrade your engine
Makes movement less fatiguing and more enjoyable
Fall Prevention and Fall Resilience
More Confidence to move safely
Can you reverse the clock?
Muscle
Mass
Strength (from 25% to more than 100%)
Power
Efficiency
Muscle Metabolism (blood sugar
regulation)
RT can increase even in advanced
ages
[18]
A two- to threefold increase in
strength can be accomplished in
three to four months
[13
]
With ongoing strength training
increase in muscle size is also
possible
[13
]
Can you reverse the clock?
Benefits of Resistance Training
Increases insulin sensitivity for the next 16-24 hours
Prevent and/or delay
osteoporosis
Reduce depression, anxiety, stress and improve
mood
[3,4,14]
Lower blood pressure and improve lipid
profile
[11,12,14]
BENEFITS TO BONE
Changes in direction even better
ex. Tennis, line dancing,
gardening and digging as well
Pull of muscles on bone strengthens them
Compressive forces of weights
No more ankle wts --Vests
RISKS OF RESISTANCE TRAINING
For those with severe untreated high BP 180/110 get
treatment before
Even treated high BP, avoid very heavy weights and
holding breath
RISKS OF PHYSICAL ACTIVITY
ACSM Position on Medical Exam and Stress Test before
physical activity over 50
Apparently healthy
individuals No Chronic Disease and
no more than 1 CHD risk
factor
Higher risk individuals
Two or more CHD risk
factors.
With or without symptoms
breakdown Individuals with chronic disease
CV, lung or metabolic disease
RECOMMENDED FOR A MEDICAL EXAM
AND STRESS TEST FOR THOSE OVER 50
Type of Activity Apparently
Health
Higher Risk
No Symptoms
Higher Risk
W/Symptoms
With Chronic
Disease
Moderate Exercise No No Yes Yes
Vigorous Exercise Yes Yes Yes Yes
Reproduced from ACSM Guidelines for Exercise Testing and Prescription, 5th ed.,
by the American College of Sports Medicine, 1995, Baltimore: Williams & Wilkins.
RISKS OF PHYSICAL ACTIVITY
Study of 51,303 cardiac patients over 5yr period.
Of 2.3 million hours of exercise only 3
sudden cardiac deaths
Good judgement and common sense
Improper Technique, Excessive Load, Overuse without
adequate rest, high impact
We were meant to be active, sedentary
lifestyle greater risk
First things first. To the women out
there… If you pick up a weight heavier than 3 lbs.
Lets Start!
This will not happen to you!
DIFFERENCE BETWEEN
STRENGTH AND POWER
Power is ability to produce as much force with as much
speed
Don’t think you need that?
One of the major factors in maintaining independence
[1]
Prevention of falls [2]
Muscular Power is lost before strength
Getting out of chair, going up steps, swinging golf club
Strength is the amount of force applied to a given load
Going down stairs, picking up objects
[15
] Muscle strength peaks in mid 20’s and is relatively
maintained into 60’s.
By 80’s strength is half of young adult [16]
DIFFERENCE BETWEEN
STRENGTH AND POWER
JUST STARTING
Develop Basic Foundation up to 8 weeks, 12-15 reps, 1-3
sets, low load
Intermediate Phase 8-24 weeks 10-12 reps, 1-3 sets, low to
moderate load
Progress Further 6 months on 8-12 reps, 1-3 sets,
moderate to vigorous load
KEEP IT SIMPLE
Don’t overcomplicate it, start moving, go slow and gradually
progress Train backside more than front
2:1, 3:1 ratio
Years of working just the mirror muscles
and/or bad posture
More pulling movements for most population
Imbalances set up for pain and reduced
performance
WORK THE MUSCLES YOU CAN’T SEE
ARE MACHINES GOOD OR BAD
There is a place in the beginning
Doesn’t translate fixed linear path, supported
Greater risk to develop asymmetries
STARTING OUT
Warm up and Movement Prep
Increased blood flow to muscles,
oxygenation and body
temperature. (rubber band)
Warm up 4-5min. 30s of ~8-10 moves
Just starting out include as part of
workout
At end should feel warm with elevated heart
rate and breathing
Static vs Dynamic Movement Prep
Tissue Quality Work Foam Roll
To Stretch or Not to
Stretch
STARTING OUT
ASSESSMENT & SCREEN
Value of: Baseline Norm and Proper Comparison
Lower Body Test 30s Chair sit
Upper Body Test 30s Arm Curl
Shoulder mobility

WHAT IS YOUR CORE?
Critically important, prehab or rehab
What is it?
Stop doing sit ups. 730lbs compression (Axler and McGill,
1997)

neutral position

adapts

Fourth grade math book
Stress and adaptation
STRENGTH VS FUNCTION
Need Strength to help function
However Stronger doesn’t equal direct
function improvement
Specificity to the task
FUNCTIONAL AGING MODEL
Train all Components of Function
Be purposeful
Train in all 3 planes of motion (Sagittal, Frontal,
Transverse) Movements before Muscles
Stand up and Stay up as much as possible
Complicated first moving to simple as you fatigue
Stay Safe. Nothing should hurt. Work vs Pain
RESISTANCE TRAINING AND
OSTEOARTHRITIS
The chicken or the
egg? Strength decline in OA due to drop in activity
Evidence Muscle weakness directly contributes to
development and progression of OA
[5]
Strength training has significant benefit in
improving function and reducing OA pain
[6,7,8]
Investigation of Resistance Training on OA
Group 2 Lower Intensity: 10 sets of 15reps at 10% of 1 RM
After 8 weeks both exercise groups “significantly”
reduced pain & improved function over control. No
adverse effects reported
Better in High Resistance but not statistically significant
between low and high
Study of 102 adults with mild to moderate Knee OA [9]
Group 1 Higher Intensity: 3 sets of 8 at 80% of 1 RM
7/10 reported pain. Moved to 60% of 1 RM
RESISTANCE TRAINING AND
OSTEOARTHRITIS
[18] Very large effect on strength in non OA group but minimal
effect on Function
In OA groups moderate effect on Strength, Function and
Pain almost identical across all three
“When older people with OA participate in strength
training the training directly targets one of the main
barriers to their functional performance.”
“The positive message from this review that should be clearly
communicated to older people with OA is
That no matter how old they are, they will probably benefit in
clinically important ways from participating in a strength
training program, as long as it provides some consistent
overload to their muscles as they exercise. ”
“The biggest challenge with any exercise program
is to maintain long-term adherence, because the
benefits of exercise will diminish if people stop
exercising.”

TIPS FOR EXERCISING WITH
OSTEOARTHRITIS
Identify when is the best time of day for you
Change methods, angles, frequency,
resistance level, body position
High and Low Intensity study both effective 8wks [9]
Dynamic and Isometric both effective 16
wks
[10]
• Move all Joints Daily
• Move inflamed joints gently through range of
motion
• Begin with warm up of slow exercises
• Take warm shower just prior
• Slow Controlled movements no bouncing
• Attempt full range of motion to point of mild
discomfort but not pain
• Listen to your body Adapted from Arthritis Foundation (2009)
