Osteoarthritis
• 27 million Americans
• F>M (after age 50)
• Other risk factors
• Genetics
• Weight
• Prior injury
• With similar amounts of radiographic changes – OA is
more symptomatic in women
Helmick et al, 2008; http://www.arthritis.org/media/newsroom/media-kits/Osteoarthritis_fact_sheet.pdf
Osteoporosis
• Decrease in bone density
• Most common type of bone disease
• 50% of women over age 50
• Symptoms: loss of height, kyphosis,
low-trauma fracture
• Diagnosis: Bone Densitometry, +/labs, XR

•  % body fat
•  weight
•  height

Sarcopenia
 Sarcopenia- the age-associated loss of skeletal muscle
mass and function.

Epidemiology
Janssen I, Heymsfield SB, Ross R. Low relative skeletal muscle mass (sarcopenia) in older persons is associated with
functional impairment and physical disability. J Am Geriatr Soc. 2002 May;50(5):889–96.
Strength
•
Greater decline in strength than muscle mass
•
•
•
Declines 15% in 6th and 7th decades and 30% after the 7th decade
Greater decline in lower body vs. upper body strength
Greater decline in extensors vs. flexors
• Power declines more than strength and muscle mass
• Weakness a more powerful predictor of morbidity/mortality in the
elderly than muscle mass

EXERCISE
Exercise – The Facts
• Inactivity increases with age
• By age 75, about 50% women
engage in no physical activity
• Walking & gardening are most
popular
• The loss of strength/stamina
attributed to aging is, in part,
caused by inactivity
http://www.cdc.gov/nccdphp/sgr/women.htm
Exercise Benefits During Menopause
• Studies have shown that
regular exercise/physical
activity leads to:
• Improved physical and mental
health
• Improved quality of life
• Reduced symptoms of
menopause in those who
exercised
• Choosing activity is important
Stojanovska L1, Apostolopoulos V2, Polman R3, Borkoles E3. To exercise, or, not to exercise, during menopause and beyond. Maturitas. 2014
Apr;77(4):318-23.
Exercise and Body Composition
•Moderate intensity
aerobic exercise
reduces total body fat
•Decrease in visceral
fat
TOTH, MJ.; BECKETT, T; POEHLMAN, ET. Physical activity and the progressive change in body composition with aging: current evidence and research
issues. Med Sci Sports Exerc. 1999; 3 (11 suppl): S590-6.
Activity Guidelines: > 65 years
• Follow adult guidelines
• 150 min of mod intensity/week
• 75 min vigorous intensity/week
• 10 min intervals
• Strengthening 2d/w
• When not possible, be as physically active as
abilities/conditions allow
• Do exercises that maintain or improve balance to reduce
risk for falling
Haskell et al, ACSM/AHA, MSSE, 2007
Exercise and Osteoarthritis
• What role does physical activity have on progression of
arthritis?
• Evidence suggest that (moderate) exercise does not accelerate
development of OA
• Possible increased risk of OA with competitive sports participation,
particularly early in life, and with competition at an elite level
• Increased risk of OA in the presence of obesity, trauma, occupational
stress, and alignment problems of the lower extremities
Running and Arthritis
• Lack of conclusive evidence that running causes arthritis
• No increase in 60 yo runners (180 min/w x 12 years)
• No increase in runners up to 28 mi/wk
• Higher incidence was seen > 65 mi/wk
• No increase in complaints of joint pain in runners vs. non-runners
• Pace may be better predictor
• Runners with arthritis may have faster progression of arthritis
compared to non-runners
Lane et al, 1986 & 1993; McDermott et al, 1983; Kujala et al, 1995
Strength Training
• Older individuals can substantially
increase their strength with
resistance exercise training
• Similar strength gains older vs.
younger
• Muscle strength increases in
response to training between 60100% of 1RM
• 15% people over 55 strength train
Bautmans I1, Van Puyvelde K, Mets T. Sarcopenia and functional decline: pathophysiology, prevention and therapy. Acta Clin Belg. 2009 Jul-Aug;64(4):303-16.
Where to start
• For a sedentary person, walking is feasible
• To start resistance training :
• Perform 8-10 repetitions of 8-10 exercises for major
muscle groups
• Start with 40% of one repetition maximum and
increase slowly
• Resistance training initially requires
professional instruction/machines
• Warm-up and cool-down with stretching
should be a part of every exercise session

Exercise in Osteoarthritis
• Combination of:
• Strength training (ST)
• Active range of motion exercise
• Aerobic activity
• Strength training:
• Resistance-based lower limb, hip and quadriceps strengthening
exercises
• Water-based exercise in knee and hip OA found benefits
for function and quality of life
• Reductions in pain and disability for overweight patients
with OA were found with weight loss (5% in 20 wks)

Managing Osteoporosis
• Julius Wolff (1891) – Bone, in a healthy subject, will adapt
to the loads under which it is placed
• Exercise  Bone remodeling
• Primary goal is reducing fracture risk
• Slow/stop bone loss
• Increase bone mass/improve bone architecture
• Maintain/increase bone strength
• Minimize risk of falls
Exercise Recommendations: Osteoporosis
• Exercises can increase bone mass if they increase
muscle mass and strength
• Muscles to target to help with posture and prevent falls:
• Back extensors
• Lower extremity muscle groups – such as the knee and hip
extensors, hip flexors, dorsiflexors and plantarflexors
• Compound movements can be effective way to target all
these areas
Tella SH1, Gallagher JC2. Prevention and treatment of postmenopausal osteoporosis. J Steroid Biochem Mol Biol. 2014 Jul;142:155-70.
Exercise in Osteoporosis
• Focus on improving agility, balance and posture
• Avoid high impact activities
• Avoid activities with a risk of fall
• Avoid repeated/resisted trunk flexion movements
• Moderate intensity physical activity can help improve
balance and agility, thereby minimizing falls
• Among women 75 or older, exercise has been shown to reduce risk
of fall and injury by 75%

T’ai Chi
• Flowing, meditative movements
• Greater loading than walking
• Reduces risk of falling
• Meta-analyses investigating t’ai chi found strong favorable
benefits of t’ai chi for improving pain and physical function
in individuals with OA
