25
Explain what leads to muscle mass decrease and the results of this. What is result of remodeling? What is the main cause of reduced strength between ages 25 and 80?
Muscle mass Decrease:
- Motor unit remodeling represents Normal CONTINUOUS process that involves motor endplate repair and reconstruction
- Remodeling leads to DENERVATION muscle atrophy which magnified by reduced physical activity, progressively Reduces muscle cross section, mass and function
- Primary cause of reduced strength between ages 25 and 80 relates to a 40-50% REDUCTION in muscle mass from muscle fiber Atrophy and Loss of motor units, even among healthy, physically active adults
26

Total number of muscle fibers and cros-sectional area are DIRECTLY Related.
as you have more muscle fibers, cross-sectional area Increases.
27
Discuss th effects of resistance training for older adults.
Resistance training for older adults
- Moderate resistance training provides a SAFE way to Stimulate protein synthesis and Retention while slowing the normal and inevitable loss of muscle mass and strength with aging.
- Older men who resistance train have GREATER absolute gains in muscle size and strength (due to men having greater cross-sectional area) than women, but percentage improvement is similar
- A regular program of aerobic, strength, flexibility, and balance training for those 70 to 89 prevents both loss of muscle strength and increase in muscle fat infiltration
- muscle responds to vigorous training with Rapid improvement into the night decade of life
28

32
What are the three hormonal system changes that occur due to aging?
Hormonal system changes due to aging:
- Hypothalamic-pituriatary-gonadal axis leading to MENOPAUSE and ANDROPAUSE( men tesotrone levels drop)
- Adrenal cortex leading to REDUCED Output of DHEA
- Growth hormone/ Insulin-like growth factor axis leading to SOMATOPAUSE.
33
Describe the potential mechanisms that underlie association between physical activity and reduced risk of cognitive decline
- Physical activity can lead to reduced vascular risk which leads to reduced cognitive decline/dementia
- Physical activity along with reduced obesity also lead to reduced vascular risk
- Reduced obesity or reduced vascular risk can lead to reduced inflammatory markers which leads to reduced cognitive decline and dementia.
- reduced inflammatory marks can lead to reduced cognitive decline/dementia which lead to enhanced neuronal function
- physical activity can cause enhanced neuronal function and hence reduced cognitive decline/dementia
34
Discuss the age-related decline in three hormone systems.
in the ANTERIOR pituitary: Growth Hormone DECREASES and causes IGF-1 in Liver and tissues to Decrease (somatopause)
- In the posterior pituitary- Corticotropic hormone and ACTH, have NO change, cortisol has NO change but DHEA DECREASES (Androgenopause)
3. The gonadotropic hormones (LSH/FSH) DECREASE causing estradiol in the ovaries to decrease (Menopause) and in testes, decreases Testosterone (Andropause)
35
Describe the changes in pulmonary function that occur with aging. What is the benefit of aerobic training for elderly individuals.
Pulmonary function
-Mechanical constraints cause Deterioration in Static and Dynamic lung function
-SLOWING of pulmonary ventilation and gas exchange kinetics during translation from rest to submaximal exercise
In elderly men, aerobic training INCREASES gas exchange kinetics to levels approaching values for fit young adults.
-Older endurance-trained athletes demonstrate GREATER pulmonary function capacity than sedentary counterparts.
36
Discuss the changes in cardiovascular function that are seen with aging. What happens to cardiac output in both trained and untrained individuals and why?
Cardiovascular function:
- VO2 max DECLINES 1% yearly and occurs TWICE as fast in sedentary Compared to Physically active
- Regular aerobic exercise CANNOT Fully Prevent age-related decline in aerobic power with aging
- Exercise maximal heart rate DECLINES with age
- Maximum Cardiac Output DECREASES IN trained and Untrained due to LOWER maximal heart rate and Stroke volume
- Compliance of Large arteries DECLINES from changes in arterial wall properties.

- Training of older person may SLOW or even Reverse decline in functional capacity
- Low- and high-intensity exercise allow elderly to RETAIN cardiovascular function at higher level than sedentary counterparts.
- After age 18, men and women progressively GAIN body mass and Fat until 5th or 6th decade
- Bone mass DECREASES 30 to 50% in those above age 60. ; weight-bearing and resistance exercise can INCREASE BONE MASS
40
Describe the relationship between age and 100M sprint performance in males and females ages 35 to 88.
The older the age, the longer it will take to run 100-M sprint

Describe what occurs in coroner heart disease and the consequences of this. What happens if arterial walls are damaged? What is the first sign of atherosclerosis
Coronary Heart Disease
- Involves DEGENERATIVE CHANGES in intimate or Inner lining of larger arteries that supply myocardium
- Damage to arterial walls begins as a multifactorial immunologically mediated, inflammatory response to injury.
- From hypertension , cigarette smoking, infection, homocysteine, elevated cholesterol, or free radicals .
- Damage INITIATES complex Series of Changes that produce lesions that bulge into vessel lumen
- initally take form of fatty streaks: FIRST Sign of ATHEROSCLEROSIS
- vessels congests and bursts with fibrous scar tissue
51
Describe the role of C-reactive protein and its function. Where is it produced?
C-reactive protein- INDICATOR of Arterial Inflammation
- Half of people with Heart disease have normal or slightly elevated cholesterol; must consider other factors like C-reactive protein (CRP) in process
- CRP produced in LIVER and ADIPOCYTES to help Fight Inflammation
- CRP levels rise during acute and chronic reactions
- Levels rise when arteries Accumulate PLAQUE
- HIGH CRP also relates to hypertension (CRP increases with people who have hypertension)
- Normal CRP=1.5 mg/dL; High CRP= 3.0-4.0 mg/dL
52
Discuss the plaque that is seen in arteries and consequences that occur if seen.
Vulnerable Plaque: Difficult to Detect, yet Lethal

An immune response likely TRIGGERS PLAQUE DEVELOPMENT within arterial walls
-Regular physical activity may STIMULATE the immune system to INHIBIT agents that facilitate arterial disease
64
Discuss what homocysteine is and how it relates to coronary heart disease
Homocysteine:
- Highly reactive, Sulfur-containing amino acid, forms as byproduct of Methionine metabolism
- High levels related to arterial or venous thrombosis by age 30
- LOCKSTEP ASSOCIATION (linear relationship) between homocysteine and heart attack and mortality in men and women.
65
Explain the mechanism or Homocysteine's Negative impact on Cardiovascular health. What is good defense for this mechanism?
Homocysteine mechanism:
1. Protein-rich foods contain an amino acid, methionine, that converts to homocysteine
2. Excess homocysteine levels damage the lining of arteries
3. cholesterol builds up inside the scarred arteries, which leads to fatal blockages (cut of blood flow)
Proposed DEFENSE:
-Vitamins in fresh foods and dietary supplements CATABOLIZE homocysteine
-vitamin B12- meat, fish and dairy products
Vitamin B6, - green leaf, vegetables, poultry, nuts, whole grain cereal, fish
-Folic acid- green leafy vegetables, fruits, organs juice, wheat germ, dried beans and peas
66
distinguish between the effects of 1 CHD risk factor vs 3 risk factors.

108
What is chronic bronchitis and why is called the Blue Boater ?
What unique characteristic feature is present in this disease?
Chronic bronchitis- long-term inflammation (swelling) of the bronchi (occurs when airways in lungs are inflamed)
- when airways are irritated and inflamed, mucus forms which makes it harder to breathe and the body does not take in enough oxygen. This causes cynaosis, which leads to one's skin and lips to turn blue (hence blue boater)
- Characteristic Emphysemic "BARREL CHEST" (where there is increased anterior-posterior chest diameter). This arises due to lung being filled with too much air and air being trapped in lungs, causing lungs to inflate like a ballon and expands the ribs.
109
