Injury

89 with 1 musculoskeletal injury since 50yo
Foot and Ankle
Knee ligament or muscle tears
Shoulder tendonitis
Lower back
Mechanism 60 overuse 23 falls
54 competition/36 practice
2005 Injury data

3
InjuryThe majority of 2001 Senior athletes
experienced at least one More than 50 had
experienced up to 5 injuries

Performance decline attributed to increased rates
of Orthopaedic Injury
(Eskurza,02,Joyner, 93, Pollack, 97).
Acute and overuse injury is 1 reason for
stopping exercise.
(Maharam, 99).

The Reason Attenuated mechanical properties and
lower healing capacity of aging muscle and tendon
(Maharam, 99).

50 yo (p 5
musculoskeletal injuries 3 x more likely to
report injuries about the knees (48 v- 18)
5
Discussion Injury and OAKnee OA predisposed
Senior Athletes to higher injury rates.

The Reasons Injury and knee OA
Quad weakness (Hassan, 01)
Altered proprioception (Bennell, 03)
Abnormal neuromuscular response may weaken muscle
response and decrease efficacy of protective
muscular reflexes.
Muscle fatigue alters proprioception (Miura, 04)
54 of Senior Athlete injuries occurred during
competition
Loss of proprioception in one knee is accompanied
by decreased proprioception in the contra lateral
knee (Koralewicz, 02)

2001 Bone Density Screen
Women 40 HRT WB NWB
Men WB NWB
7
Bone Mineral DensityEven the very old (75yo)
athletes have lower rates of Osteoporosis than
their non-athletic peers

Low BMD is one of the major factors in Lost
independence
The impact of Osteoporosis can be attenuated with
exercise
Modest exercise, including brisk walking, reduces
the rate of bone density loss among
postmenopausal women (Preisinger, 95,96)
Regular walking reduces the risk of Osteoporotic
fractures by 30 (Cummings, 95).
