Study Notes

Posture

Posture involves maintaining a straight, upright body during activities like sitting, walking, and sleeping.
Poor posture develops from prolonged sitting, computer work (over 8 hours), or prolonged standing/driving.
Good posture trains the body for minimal strain, aligning bones and joints, reducing wear and tear, and preventing spine misalignment.
Once learned, good posture becomes automatic.
Good posture requires proper sitting/standing posture (straight back, upright shoulders), balanced weight distribution on hips, and correct lifting techniques (firm footing, wide stance, bending at knees/hips, lifting smoothly).
Supportive footwear helps with prolonged standing or lifting heavy objects. Avoid shoes affecting balance and posture.
Inflexibility increases the risk of joint and muscle injury. Flexible muscles improve athletic performance as activities become easier and less exhausting.

Body Fat

Body fat is the proportion of fat in the body.
A 150-pound person with 10% body fat has 15 pounds of fat. Remaining weight is lean body mass.
Essential body fat is needed for regulating body temperature, protecting organs, and providing energy.
Body fat percentages are used for classification:
- Slim (males: 2-4%, females: 10-12%)
- Athletic (males: 6-13%, females: 14-20%)
- Fit (males: 14-17%, females: 21-24%)
- Average (males: 18-25%, females: 25-31%)
- Overweight (males: 25%+, females: 32%+)
Measuring Body Fat:
- The pinch test estimates body fat by skinfold thickness measurements at various body sites (triceps, biceps, abdomen, thighs).
- Skinfold calipers measure the thickness in millimeters.
- Sum of seven skinfold readings is typically calculated.

Body Mass Index (BMI)

BMI indicates ideal body weight relative to height.
Calculation:
- Using kilograms (kg) and meters (m): BMI = weight (kg) / [height (m)]²
- Using pounds (lb) and inches (in): BMI = weight (lb) / [height (in)]² x 703
BMI categorizes individuals based on weight: underweight, healthy weight, overweight, obese.
Factors besides BMI need to be considered for assessing health risks: skinfold measurement, diet and exercise, blood pressure, and family history.
BMI interpretation differs for adults and children, and is dependent on age, race, and gender (e.g., women tend to have higher body fat than men). Body fat increases with age.
Initial assessment after BMI evaluation often involves waist circumference measurement to assess abdominal fat.
High BMI with low abdominal fat is not considered a high risk.
Individuals with BMI in danger zone (overweight/obese) and other health risks (e.g., high cholesterol, hypertension) should consider weight loss.
BMI limitations: BMI doesn't differentiate between fat and muscle; changes in BMI over time can be due to either fat or muscle changes. Athletes have higher BMIs due to muscle mass, not necessarily fat.
