Concepts Flashcards
What is the purpose of health-related fitness testing?
- Establish person’s cardiovascular and metabolic status
- Gaining a sense of baselines physiological parameters
- Identify movement asymmetries that may cause injury
- Knowing person’s capacity so they are not over-exerted
- Checking-in along the way
- Being able to monitor change or improvement (physical, emotional)
1. Pre-exercise Screening
Purpose
Components
- Record baseline measurements, identify health issues, determine risk stratification
- Identify signs of cardiovascular, respiratory, or metabolic disease
- Identify pre-existing cardiovascular, respiratory, or metabolic conditions
- Medical history, physical examination, laboratory tests
Risk Factors (7)
- Family history of coronary heart disease
- Smoking
- Hypertension
- Dyslipidemia
- Impaired fasting glucose
- Obesity
- Sedentary lifestyle
RISK STRATIFICATION
Low-risk
Age (men & women)
Max # risk factors
Exercise tolerance (intensity)
- Men less than 45, women less than 55
- 1 risk factor; asymptomatic
- Vigorous (maximal) activity
RISK STRATIFICATION
Moderate-risk
Age (men & women)
Max # risk factors
Exercise tolerance (intensity)
- Men 45+; women 55+
OR
- 2 or more risk factors
- Moderate (sub-maximal) activity
RISK STRATIFICATION
High-risk
Age (men & women)
Max # risk factors
Exercise tolerance (intensity)
- None specified
- Individuals with cardiovascular, respiratory, or metabolic diseases; or symptoms suggestive of these diseases
- Seek medical clearnace prior to exercise
2. Organization of Exercise Tests
- Resting measurements (HR, BP, body comp)
- Cardiorespiratory endurance
- Muscular strength
- Muscular endurance
- Flexibility
Problem Solving Steps (5)
- Define the problem
- Identify the issues
- Consider the information and its implications
- Generate ideas and create a potential solution
- Reflect on the problem and outcome
Approaches Used to Measure HR (4)
- Auscultation
- Palpation
- HR monitors
- Electrocardiogram
Approaches Used to Measure BP (3)
- Intra-arterial pressure measurements
- Sphygmomanometry
- Oscillometry
Approaches Used to Measure Body Comp
- Skinfold measurements
- BMI
- Waist-to-hip ratio
- Dual Energy X-ray Absorptiometry (DEXA)
- fat mass vs. fat free mass
- Underwater weighing
- multiple components
Approaches Used to Measure Aerobic Fitness (Ventilation and VO2)
Lab Test(s)
Field Tests
- Graded exercise test
- Stop when O2at steady state (max)
- Stop at pre-determined workload (sub-max)
- VO2max prediction equation
- 9 or 12 min run test
- Step test
- Bike or swimming test
Approaches Used to Measure Musculoskeletal Fitness
- Dynamometers for isometric (static) strength
- Free weights or machines for dynamic strength
- 4, 6, or 8RM tests
Approaches Used to Measure Flexibility
- Goniometer
- Leighton flexometer
- Sit-and-reach box
