Reduction in height starts at about 35-40, What are the factors for why this happens
|
1. CDompression of the intervertebral disks
2. Poor posture 3. Osteopersosi |
|
|
3 reasons why we gain weight
|
1. Diet
2. Inactivity 3. Reduced ability to mobilize fat stores |
|
|
Sacropenia
|
the loss of muscle mass
|
|
|
Osteopenia
|
Severe loss in bone mass
|
|
|
Why does muscle mass decrease after 40
|
1.Inactivity
2. Decreased rate of protein synthesis Which leads to negative nitrogen balance and net loss of muscle |
|
|
WHy do they .experienc bone loss
|
With agin, resorption exceeds synthesis, resulting in a net loss of bone.
|
|
|
Older adults experience changes in body composition due to exercise training similar to those for younger adults.

|
Losses in isokinetic strength are greatest at high angular velocities and losses in concentric strength are greater than losses in eccentric strength

|
Fiber type remains unchanged through life
|
FIber tyep remain
|
|
|
WHy do fiber 2 motor neurons decrease during agin
|
THe death of motor neurons die in the spinal cord and are absorbed by the body.
|
|
|
THe size of both type 1 and type 2 fibers decreases with aging
|
THe size of both type 1 and type 2 fibers decreases with aging

VO2 max decline also about 1 percent a year
|
VO2 max decline also about 1 percent a year
|
|
|
What factors influence the rate of decline of vo2 max
|
1. genetics
2. General acticity level 3. Intensity of training 4. Volume of trainng 5. Age Range |
|

|
Older people are less tolerant of environmental stress than their younger conterparts
|
Older people are less tolerant of environmental stress than their younger conterparts
|
|
|
Heat stress is a problem for older people why
|
Reduced aerobic capacity. Increasing aerobic capacti cna increase skin blod flow, cincrease sweating rate, and improve redistibution of blood to the skin and muscles.
|
|
|
Old people don't do good in the cold either
|
Reduced abliity to generate mteabolic heat.
