The document discusses the aging process in athletes, highlighting the physiological changes that occur with age, including declines in muscle mass, bone density, and hormonal levels. It emphasizes the importance of exercise, especially strength training and adequate nutrition, in mitigating these effects and maintaining health, alongside a comprehensive health program for aging athletes. Additionally, it touches upon hormonal treatments like testosterone replacement for improving body composition and quality of life in older athletes.

Sarcopenia:
• Cross sectional studies of subjects >75 y.o.,
estimate annual muscle mass loss of 0.8-0.9% in
men and 0.64-0.70% in women (Miller, et al, 2012)
• Exercise is essential for rebuilding strength and
decreasing risk of falls, CV events and bone loss
in elderly pts (Allen, et al, 2011)

• Maximal oxygen uptake. Evaluation of
Cardiopulmonary Fitness
• Measured ml O2/kg/min

15. Normative Values

16. VO2 Decrease w/
Aging
• Sedentary: non-linear loss starting in
20’s/30’s
• Active: non-linear loss upon ceasing
activity
• 70’s: Lose up to 22%/yr, non-linear
regardless of activity
• Baseline 6-10% decline per decade
regardless of activity level

Consumption Decline w/
Aging
• HR max ↓ 3-5% (regardless of exercise
or sex) *major role
• Max CO reduced in athletic older adults
• Decreased LBM (up to 35% decline in
VO2)

18. Mitochondrial Dysfxn
Mitochondria Function:
o oxidative metabolism creating energy
from fat, cho, protein
o Involved with free radical formation
o Thought to be a cause of aging. Cellular
death, apoptosis
o “Inflamaging”-Telomere Shortening
Melov S., Tarnopolsky MA. Resistance exercise reverses aging in Human skeletal muscle. PloS ONE, 2007.

• Endurance exercise partly normalized
age-related mitochondrial dysfunction
• Found to increase skeletal muscle-
mitochondrial electron transport chain
activity in older men/women

mass (+2.7 kg) and increased fat loss (-2.0
kg) according to ACE systematic review

strength than placebo, but no conclusive
data on LE muscle mass
•QoL – physical function quality of life

37. Continuum of Your Life
Where do you want your levels to be?
T = 10 ng/dl T = 7000 ng/dl

38. Provocative Dialogue
• “Treating Everyone Fairly doesn’t mean treating everyone the
same”
• What is normal
• What is true measure of performance enhancement?
• What role do unique bodies play in this issue?
• 18 yo athlete with testosterone level of 1500 vs 35 yo
athlete, same sport with 300?
• What about our non-professional athletes and active
population? How far do you go with treatment in a solid
clinical, evidence based setting?

39. In my opinion
We have the population
And the 360 approach.
We need research
On
the
Athletes we manage,
who want to
push the upper limits of
normal
on existing replacement
