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.
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
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
The number of capillaries per unit area is similar in young and old endurance runners.
The number of capillaries per unit area is similar in young and old endurance runners.
Storke volume max is typically farily well maintained in highly trained older adults
Storke volume max is typically farily well maintained in highly trained older adults
Decreased cardiac output with age is due to lower hr max
Decreased cardiac output with age is due to lower hr max
Peripheral blood flow decreases with agin
Peripheral blood flow decreases with agin
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
Lactate Threshold declined with age
Lactate Threshold declined with age
Aging apperas to neither impair the ablitiy to improve muscle strenth notr prevent muscle hypertrophy
Aging apperas to neither impair the ablitiy to improve muscle strenth notr prevent muscle hypertrophy
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.
