Study Notes
Assessing Intensity of Physical Activities
- Physical activity encompasses various movements, including recreational activities, active transportation, and household chores.
- Activities are categorized into leisure-time activities, commuting activities, household activities, and occupational activities.
- Regular physical activity reduces noncommunicable disease risk.
Intensity of Physical Activities
- Intensity is assessed on a subjective scale (0-10).
- Moderate intensity is rated 5 or 6.
- Vigorous intensity is rated 7 or 8.
- The metabolic equivalent of task (MET) is another measure.
MET Values
- One MET is the energy expenditure of sitting quietly (3.5 ml O2 / kg / min).
- Moderate activities are 3-6 METs (e.g., dancing, brisk walking).
- Vigorous activities are 6+ METs (e.g., running, high-impact aerobics).
Physical Inactivity and Noncommunicable Diseases (NCDs)
- NCDs are non-infectious and non-transmissible medical conditions.
- Examples of NCDs include cardiovascular diseases, stroke, diabetes, certain cancers, osteoporosis, and mental health issues.
- The prevalence of NCDs is rising, particularly in low- and middle-income countries.
- Physical inactivity is a significant risk factor for mortality and NCDs.
Incorporating Physical Activity into Daily Life
- To combat physical inactivity, incorporate more physical activities into daily routines.
- Examples include walking/biking to work/school, taking the stairs, household chores, and walking the dog.
- Structured recreational activities are also essential.
Global Recommendations for Physical Activity
- Children and Adolescents (5-17 years): At least 60 minutes of moderate to vigorous physical activity daily.
- Adults (18-64 years): At least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity activity per week.
- Older Adults (65 years and above): Regular physical activity that enhances balance and prevents falls, along with aerobic activities.
The Cardiorespiratory System and Exercise
- The cardiorespiratory system facilitates the exchange of nutrients, oxygen, and waste products between blood and tissues.
- It consists of the heart, blood vessels, and blood.
- The heart has four chambers: two atria (receiving chambers), and two ventricles (pumping chambers).
- The cardiac cycle involves systole (contraction) and diastole (relaxation) phases.
Blood Pressure
- Blood pressure is measured during the cardiac cycle.
- Systolic pressure is the pressure during contraction (110-140 mmHg).
- Diastolic pressure is the pressure during relaxation (75-80 mmHg).
Effects of Exercise on the Cardiovascular System
- Exercise increases heart rate and blood pressure to meet increased oxygen demands.
- Cardiac output (CO) is the amount of blood pumped by the heart per minute.
- Stroke volume (SV) is the amount of blood ejected per contraction.
- Fitness improves heart efficiency, leading to lower resting heart rate and higher cardiac output.
Understanding Cardiovascular Disease
- Cardiovascular disease (CVD) encompasses conditions affecting the heart and blood vessels.
- Key types include coronary heart disease (CHD), stroke, and hypertension.
- CHD is the leading cause of death, characterized by reduced blood supply to the heart.
- Stroke occurs when the brain is deprived of oxygen-rich blood.
- Hypertension is persistently high blood pressure.
Obesity and Overweight
- Overweight is defined as a body weight exceeding ideal weight by 10%.
- Obesity is defined as a body weight exceeding ideal weight by 30%.
- Weight assessment methods include BMI and waist circumference.
Diabetes and Cardiovascular Disease
- Diabetes Mellitus (DM): High blood sugar due to insulin dysfunction.
- Type 1: Pancreas produces little or no insulin.
- Type 2: Insulin production is sufficient, but cells are resistant to its effects.
Nutrition for an Active Lifestyle
- Maintain a balanced diet for an active lifestyle.
- Macronutrients are carbohydrates, fats, and proteins.
- Micronutrients include vitamins and minerals.
- Water is essential for hydration.
Hydration
- Water loss occurs while urinating, perspiring, breathing, and defecating.
- Recommended daily water intake: 2.7 liters for women, 3.7 liters for men.
- Hydration is crucial during exercise.
Body Image and Eating Disorders
- Body image is an individual's perception of physical appearance.
- Types of eating disorders include anorexia nervosa, bulimia nervosa, and binge eating disorder.
- Anorexia nervosa is characterized by extreme food restriction and distorted body image.
- Bulimia nervosa involves binge eating followed by compensatory behaviors (e.g., vomiting).
- Binge eating disorder is characterized by consuming large amounts of food without purging.
Causes of Eating Disorders
- Eating disorders can result from biological, psychological, and sociocultural factors.
Alcohol Misuse and Abuse
- Alcohol is a psychoactive substance.
- Blood Alcohol Concentration (BAC) measures the amount of alcohol in the bloodstream.
- Excessive alcohol intake poses risks including injuries/deaths, sexual assaults, academic and legal issues.
