Chapter 16 - Chronic Health Conditions and Physical of Functional Limitations Flashcards
Daily Physical Activity Recommendations
60 minutes or more
Children and Endurance Activity
Can perform endurance activities well due to their high peaks oxygen uptake levels
Children and Submaximal Oxygen Demand
Child tend to exercise at a higher percentage of their peak 02 uptake during submaximal exercise compared with adults leading to greater chances of fatigue during high-intensity tasks
Children and Glycolytic Enzymes
Children producing less gylcolytic enzymes put them at a disadvantage when compared to adults when participating in short-duration, high intensity anaerobic activities
Glycolytic Enzymes
Required to support anaerobic power
Children and Hotter Environments
Higher submaximal oxygen demands and lower sweating rates causes a low tolerance for exercise in hot, humid environments
Resistance Training for Youth
Can lead to significant gain in levels of strength beyond that normal associated with growth and development
-Shown to improve motor skills such as sprinting and jumping, body composition, and bone mineral density
Aging and Degeneration
Aging has become synonymous with degeneration and loss of functional ability in older adults
Typical Forms of Degeneration Associated with Aging
- osteoporosis
- arthritis
- LBP
- obesity
Physiologic Changes and Aging
Some considered pathologic (relating to disease) and some considered normal with aging
Arteriosclerosis
Refers to hardening (and loss of elasticity) at the arteries leading greater resistance to BF and thus higher BP
-normal physiologic process of aging
Atherosclerosis
Buildup of fatty plaque in arteries leading to narrowing and reduced BF
-Caused by poor lifestyle choices
Peripheral Vascular Disease
A group of diseases in which blood vessels become restricted or blocked
-Typically a result of atherosclerosis
Prehypertensive
BP between 120/80 and 139/89
Walking and Degenerative Aging
Walking is one of the most important and fundamental functional activities affected with degenerative aging
-Reduces independence of an individual and can lead to an increase in the degeneration cycles/process
Degenerative Cycle and Physical Activity
Can slow or reverse the cycle
Flexibility in Seniors
Is important as they tend to lose the elasticity of their CT, which reduces movement and increases risk of injury
Obesity Definition
The condition of subcutaneous fat exceeding the amount of lean body mass
Body Mass Index
Used to estimate healthy body weight ranges based on height
BMI Formula
BW (kg) / Height (m^2)
Normal BMI
18.5-24.9
Overweight BMI
25-29.9
Obese BMI
30 or greater
Primary Cause of Obesity
Energy balance (too many calories consumed and too few expended)
Body Weight and Gait Mechanics
Have a positive correlation
Training Focus for Obese Clients
-Energy expenditure, balance, and proprioceptive training
Obese Clients Calorie Expenditure
200-300 kcal per session, minimum goal of 1250 weekly
Training Priority for Obese Clients
Sustained long-term aerobic endurance activities
Obese Clients and Body Position
Keep clients out of supine or prone positions and rather in standing or seated positions to keep client comfortable and avoid hyper or hypo tensive responses
Obese Clients and Orthopedic Stress
Recommended to engage in weight-supported exercises (cycling and swimming) to decrease stress on bones
Diabetes
A chronic metabolic disorder caused by insulin deficiency which impairs carb usage and enhances usage of fat and protein
Type 1 Diabetes
Body does not produce enough insulin
-Specialized cells in the pancreas called beta cells stop producing insulin, causing blood sugar levels to rise resulting in hyperglycemia
Hyperglycemia
High blood sugar
Hypoglycemia
Low blood sugar
Exercise and Glucose Utilization
Exercise increases the rate at which cells utilize glucose
Type 2 Diabetes
Associated with obesity
-These individuals produce adequate amounts of insulin but their cells are resistant to insulin and therefore cannot transfer adequate amounts of blood sugar into the cell leading to hyperglycemia
2 Goals for Diabetics
weight loss and glucose control
Neuropathy
Loss of protective sensation in feet and legs
Obesity and Weight-Bearing Activities
need to be monitored to avoid blister and foot microtrauma that could result in foot infections
Hypertension
Consistently elevated arterial BP
BP greater than 140/90
Prehypertensive
BP between 120/80 - 135/85
Hypertension Common Causes
Smoking, diet high in fat, and excess weight
Hypertension Health Risks
Increased risks for strokes, CV disease, chronic heart failure, and kidney failure
Reducing BP
can be done by making better lifestyle choices such as activity, diet, and smoking
