Study Notes
Body Composition
- Body Mass Index (BMI) measures height and weight to determine obesity levels.
- The Bod Pod technique utilizes air as a fluid medium to measure body volume.
- Skinfold measurements must be conducted on the right side of the body for consistency.
- An adult woman with a waist circumference of 97 cm is classified as having a high risk of obesity.
- Fat Free Mass is calculated by subtracting Fat Mass from total body weight in kilograms.
Measurement Techniques
- Density is calculated as Mass divided by Volume.
- Bioelectrical Impedance Analysis (BIA) measures lean body mass, fat mass, and total body water.
- The skinfold technique assumes the amount of subcutaneous fat reflects overall body fatness.
- Various factors can impact the accuracy of Bioelectrical Impedance Measures.
Cardiorespiratory Fitness
- VO2 max is a key indicator of cardiovascular capacity.
- An individual's VO2 max is influenced by multiple physiological systems.
- Objectives of cardiorespiratory fitness testing do not include eliminating individuals from participation.
- Effective cardiorespiratory tests should not excessively push clients to maximal effort.
- Clients should not necessarily avoid prescribed medications before testing to ensure accuracy.
Testing and Calculations
- Several methods exist for estimating VO2 max using specific tests, such as the Rockport 1 mile walk test, 1.5 mile run test, Submaximal Cycle test, and Queens College Step test.
- VO2 max values calculated for different tests include:
- Rockport Test: 30 ml/kg/min for a 70 kg male, age 37.
- 1.5 Mile Run Test: 57 ml/kg/min for a 27-year-old male.
- Submaximal Cycle Test: 43 ml/kg/min for a 35-year-old female at 63 kg.
- Queens College Step Test: 41 ml/kg/min for a 21-year-old female.
Physical Performance Indicators
- A 38-year-old male with a relative VO2 max of 47.4 ml/kg/min falls into the "good" classification.
- Eccentric action occurs when a muscle is lengthening during a contraction.
