Study Notes
Order of Assessment
- Four key assessments: body composition, cardiorespiratory fitness, muscular fitness, and flexibility.
Body Composition Assessment Techniques
- Techniques include hydrostatic weighing, bioelectrical impedance, skinfolds, DEXA scans, and Bod Pod assessments.
Bioelectrical Impedance Analysis (BIA)
- BIA measures resistance to low-level electrical currents, indicating composition based on fat tissue's conductivity.
- Useful for pre- and post-assessment measurements.
- Results are sensitive to an individual's hydration status.
BIA Pretest Conditions
- Require no food or drink within 4 hours before testing.
- No exercise within 12 hours of the test.
- Urination should occur within 30 minutes prior to testing.
- No alcohol consumption in the past 48 hours.
- Limit diuretic agents like caffeine or chocolate.
BIA Shortcomings
- Standard error ranges from 4-6%.
- Tends to overestimate lean body mass.
- Often underestimates levels of obesity.
Skinfold Calipers
- Measure subcutaneous fat by pinching areas of skin and fat with tongs.
- Thickness of skinfold is recorded using a gauge, allowing calculation of body fat percentage.
Caliper Reading Time
- Read caliper measurements 1-2 seconds after the pinching is released.
Relevant Skinfold Sites
- Common sites for skinfold measurements include abdominal, triceps, chest, midaxillary, subscapular, suprailium, and thigh.
BMI Underweight Classification
- Defined as a Body Mass Index (BMI) of less than 40 kg/m².
Ideal Body Weight (IBW) for Females
- Calculated as 100 lbs + 5 lbs for each inch over 60 inches, with adjustments of +10% for a large frame and -10% for a small frame.
Ideal Body Weight (IBW) for Males
- Calculated as 106 lbs + 6 lbs for each inch over 60 inches, with the same adjustments for frame size as for females.
Waist Circumference
- Measured at the narrowest part of the torso, above the umbilicus and below the xiphoid process, important for assessing health risks.
Increased Risk Waist Size for Women
- A waist circumference greater than 35 inches (88 cm) indicates increased health risk.
Increased Risk Waist Size for Men
- A waist circumference greater than 40 inches (102 cm) indicates increased health risk.
Waist-to-Hip Ratio (WHR)
- Calculated by dividing the waist measurement by the hip measurement, useful for assessing fat distribution.
Measuring Hip Circumference
- Taken at the widest part of the hips, just above the gluteal fold.
Increased Risk WHR for Women
- A WHR of greater than or equal to 0.86 signifies increased health risk.
Increased Risk WHR for Men
- A WHR of greater than or equal to 0.95 indicates increased health risk.
ACSM Recommendations for Weight Loss
- Aim for a long-term body weight reduction of at least 5-10%.
- Create a daily caloric deficit of 500-1000 kcal to achieve gradual weight loss (1-2 lbs/week).
- Recommendations for exercise: at least 50-60 minutes per day totaling 300 minutes per week at moderate intensity, with variations for low-fit individuals.
Recommended Order of Fitness Assessments
- Sequence: body composition, cardiorespiratory fitness, muscular fitness, and flexibility.
- Order is crucial for accurate outcomes, as some assessments can affect hydration and heart rate.
WHR Demarcation Point for Young Women
- A WHR greater than 0.86 indicates a high health risk for young women, highlighting gender differences in fat distribution.
