Study Notes

Hypokinetic Conditions

Hypokinetic conditions are characterized by a lack of movement, primarily caused by insufficient physical activity.
Examples include heart disease, type II diabetes, stroke, and high blood pressure.

Atherosclerosis

Atherosclerosis involves the clogging of arteries with plaque, significantly impacting coronary arteries supplying the heart.

Coronary Arteries

Supply blood to the heart muscle, crucial for maintaining heart health.

Plaque Composition

Plaque primarily consists of fats, cholesterol, calcium, and various substances found in the bloodstream.

Cholesterol

A soft, waxy substance present among lipids in the bloodstream, crucial for various bodily functions.

Sources of Cholesterol

Dietary sources include meats, poultry, fish, and dairy products.

Liver Function in Cholesterol Management

High liver activity involves the removal of cholesterol from arteries.
Low liver activity results in increased production and secretion of cholesterol into the arteries.

HDL and LDL Cholesterol

HDL (High-Density Lipoproteins) is known as "good cholesterol," facilitating the removal of plaque and cholesterol from the heart.
LDL (Low-Density Lipoproteins) is regarded as "bad cholesterol"; elevated levels lead to plaque accumulation in arteries.

Heart Attack

Occurs when a coronary artery is fully blocked, preventing oxygen delivery to heart muscle, also known as coronary thrombosis.

Causes of High Blood Pressure

Contributing factors include smoking, alcohol consumption, stress, excessive salt intake, genetics, and lack of exercise.

Hypertension

Refers to consistently high blood pressure, which can lead to severe health complications.

Blood Pressure Measurements

Systolic pressure measures the highest artery pressure after heartbeats (normal value: 120).
Diastolic pressure reflects lowest artery pressure before heartbeats (normal value: 80).

Stroke

A life-threatening condition caused by blockage or rupture of a blood vessel in the brain, restricting oxygen flow (3rd leading cause of death).

Stroke Impacts

Can affect movement, thinking, and speech capabilities, with potential fatal outcomes.

Cardiovascular Disease Risks

Primary risk factors include a sedentary lifestyle, high-fat diet, elevated cholesterol, high blood pressure, and smoking.
Secondary risks encompass stress and excessive alcohol consumption.

Diabetes

Characterized by excessively high blood sugar levels; type I diabetes is hereditary and affects 10% of cases while type II diabetes is linked to lifestyle choices.

Hypoglycemia

Represents low blood sugar levels, which can lead to various health issues.

Insulin

A hormone secreted by beta cells in the pancreas, essential for regulating blood sugar levels.

Cancer

Defined by the growth of abnormal cells, making it the second leading cause of death.

Cancer Mechanism

Cancer cells invade normal cells and can deprive them of nutrients.

Hypokinetic Cancers

Specific cancers such as colon and breast cancer are classified as hypokinetic due to lifestyle factors.

Osteoporosis

A condition marked by weak bones resulting from low bone density, increasing fracture risk as one ages.

Osteoporosis Prevention

Preventive measures include regular exercise, building muscle around bones, increasing calcium intake, maintaining good nutrition, and seeking medical guidance.

Obesity

Defined as having a high body fat percentage influenced by genetics and environmental factors.

Body Fat Importance

Serves as insulation, shock absorption, and energy storage within the body.

Hyperkinetic Conditions

Develop from excessive physical activity, leading to conditions like bone, joint problems, and muscle soreness or strains.

Body Image Disorder

A mental illness leading to an excessive preoccupation with body image, impacting mental health and self-esteem.
