Q

Outline the following hypokinetci diseases> coronary heart disease, stroke, hypertension, obesity, type 2 diabetes, osteoporosis

A

coronary heart disease:
Blockage in coronary arteries. Overtime your arteries can become clogged up with fatty substances,cholesterol, etc.
therefore, the arteries of the the heart cannot deliver enough oxygenated blood to the heart.

Stroke: occurs when the blood supply to brain is cut off, blood clots from in blood vessels in the brain, cutting off oxygen.
FAST> Face: Paralised face, can’t smile or more Arms: can’t lift or keep up arms Speech: Slurred, garbled, can’t take

Hypertension: when the blood pressure of blood vessels is too high due to narrow blood vessels because of plaque build up

obesity: Excess body fat to the point in which health is compromised.
BMI> overweight is over 25 obese is over 30

Can lead to: type 2 diabetes, coronary heart dieses, cancer breast or bowel, stroke

Type 2 diabetes: When sugar (glucose) levels are too high in the blood, bodys ability to produce/respond to the hormone insulin is impaired, resulting in abnormal metabolism of carbohydrates and elevated levels of glucose in the blood and urine.
Can cause chronic issues with the nervous and circulatory and immune system.

Osteoporosis: when bone mass density and bine mineral density is low. condition that weakens bones, making them fragile a more likely to break
↳ Losing bone is normal with age but for some people it can lead to osteoporosis

Q

Studies of different populations provide evidence of the link between physical activity and hypo kinetic diseases

A

High income countries have large coronary heart disease and stroke death. Access to cheaper food and more office jobs…., can take bus to school instead of walking

People in physically active jobs (ticket person, construction) have lower risk of hypokinertic diseases than those in a sedentary job (office)

Q

Coronary circulation

A

how blood transfers through heart and how blood supplies itself

Right coronary arteries (is on the right side and above right ventricle)
Circumflex artery ( left side and kinda above left atrium)
Left anterior descending artery ( left side kinda above left ventricle, descending)

left and right coronary arteries, circumflex artery, left anterior descending artery
coronary circulation refers to the circulation of blood within the blood vessels of the heart muscle
↳ ensures that the heart muscle receives an adequate blood supply for its metabolic needs

Describe the aim of exercise in individuals with a hypo kinetic disease
- To move the most of limited functional capacities - to alleviate or provide relief from sympotoms - to reduce the need for medication - to reduce the risk of disease reoccurrences (secondary prevention) - to help overcome social problems and psychological distress
28
Discuss the potential barriers to physical inactivity
- uncontrolled disease state (unstable angina (chest health, heart blood flow) , poorly controlled diabetes, uncontrolled hypertension) - hazards of exercise (cycle and swimming accidents) - muscuoloskeletal injuries - triggering of other health issues (heart attacks, respiratory tract infection)
29
Define the term mood
A state of emotional or affective arousal of varying, and not permanent, duration - feelings of elation or happiness lasting several hours or even a few days are examples of mood
30
Outline the effects of exercise on changing mood states
- Research suggests exercise is one of the most effective methods of alleviating a bad mood - research supports the use of exercise in modifying fatigue, anger, anxiety, depression and enhancing the positive mood of vigour, clear thinking, energy, alertness, increase sense of well-being
31
Outline how exercise enhances psychological well-being
Both psychological and physiological factors contribute to psychological well-being from exercise PSYCHOLOGICAL- distraction from daily hassles and routines, enhanced feeling of control, feeling of competency, positive social interactions, improve self-concept and self esteem PHYSIOLOGICAL - increases in cerebral blood flow, changes in brain neurotransmitters (norepinephrine, endorfines, serotonin), increase in maximal oxygen consumption and delivery of oxygen to cerebral tissues, reductions in muscular tension, structural changes in the brain
32
Explain the role of exercise in reducing the effects of anxiety and depression
Anxiety reduction- accuse effects of exercise on state anxiety, compounding effects of intensity and duration of exercise, chronic effects of exercise on trait anxiety Depression reduction - (depression is a clinical condition treated by medicatin) exercise has been seen to play a significant role in alleviating depression although it is correlational relationship> no causal link has been established Nature of exercise - Enjoyable - aerobic or rhythmic - absence of interpersonal competition - closed and predictable environments - moderate intensity - 20 to 30 minutes serval times a week
33
Discuss potential personal and environmental barriers to physical activity
Personal barriers - Demographic variables - cognitive variables - past behaviour Environmental - social environment - physical environment - Time - Characteristic of physical activity offered - leader qualities - social and cultural norms within various ethnic groups
34
Descirbe strategies for enhancing adnerence to exercise
Environment approaches - prompts - contracting - perceived choice Reinforcement approach - reward for attendance and participation - External feedback - self - monitoring Goal - setting and cognitive approach - Associative vs dissociative focus during exercise Social support approaches - role of signifiant others - Community joining in - adjusting routines - transportation - providing equipment
35
Outline the possible negative aspects of exercise adherence
Negative addiction to exercise - life choices - relationship issues Sympotoms of negative exercise - stereotyped pattern with a regular schedule of once of more daily - Ngetaive mood affected with withdrawal - Increased priority of exercise - increased tolerance to exercise - subjective awareness of compulsion to exercise
36

44
9. 4 outline the different types of Injuries common in different sports
swimming: Swimmers shoulder, neck injuries, lower back pain, rotator cuff teas Football: Ankel sprains, knee Injuries, meniscus tear, concussion Gymnastics and horse riding: Spinal injuries, fractures cycling and rugby: concussions NFL Injuries: Knee, ankle, upper leg, shoulder, head ↳ lower limb Injuries are the most common
45
9. 5-outline the common causes of running-related Injuries
· Rapid In training distance or intensity · Running surface · Footwear Previous Injuries · Running experience · Biomechanical Imbalance · Twists and turns
46
9. -Explain now risks and hazards of exercise can be reduced
Regular moderate exercise · Protective equipment Regular health a wellness evaluations with a medical professional Injury prevention strategies (warm-up, cool-down, stretching · Injury prevention education for coaches, referees, and athletes
47
9. 7-Evaluate the benefits and hazards of exercise with regard to health
The risks associated by strenuous exercise may be outweighed by the benefits of physical activity Habitual, moderate to vigorous exercise protects against CHD · Moderate exercise (jogging, walking, cycling)also pose a risk of Injury through collisions with vehicles and falls
