ACE PTM Ch. 8 - Physiological Assessments Flashcards
(51 cards)
List some key focuses of common health related assessments.
- Cardiorespiratory fitness
- Body composition & anthropometry
- Muscular endurance
- Muscular strength
- Flexibility
Define anthropometry.
The scientific study of the measurements and proportions of the human body.
What does a cardiorespiratory fitness test measure?
- Overall functioning of the heart and lungs
- Efficiency of the cardiovascular system in delivering oxygen to working muscles
What does a muscular endurance test measure?
The ability of muscle groups to sustain repeated activity and withstand fatigue.
What does a muscular strength test measure?
The ability of a muscle to overcome external resistance.
What does a flexibility test measure?
The range of motion (ROM) of a given joint or group of joints, or the level of tissue extensibility that a muscle group possesses.
Name some key focuses of common skill related assessments.
- Anaerobic power
- Anaerobic capacity
- Speed
- Agility
- Reactivity
- Coordination
What does an anaerobic power test measure?
The amount of work performed in a given unit of time (usually represents one single and explosive bout, event or repetition performed at maximal efforts)
What does an anaerobic capacity test measure?
The sustainability of power output for brief periods of time.
What does an agility test measure, and what three stages does agility testing involve?
How accurately and rapidly a person can change direction. Acceleration, stabilization, and deceleration.
What is reactivity?
The rate at which an individual responds to a stimulus.
What is coordination?
The ability of an individual to complete complex movements while providing accurate responses in both timing and intensity.
What is important to be aware of during the administration of any exercise test involving exertion?
Any identifiable signs of symptoms that merit immediate test termination.
What signs and symptoms merit immediate exercise test termination?
-Angina, chest pain or angina-like symptoms
-Significant drop (>10mmHg) in SBP despite increase in exercise intensity
-Excessive rise in BP: SBP reaches .250 mmHg or DBP reaches >115 mmHg
-Excess fatigue, shortness of breath or wheezing (heavy breathing is ok)
-Signs of poor perfusion: lightheadedness, pallor (paleness), cyanosis (bluish coloration), nausea, or cold
and clammy skin
-Increased nervous system symptoms: ataxia, dizziness, confusion, or syncope
-Leg cramping or claudication
-Subject requests to stop
-Physical or verbal manifestations of severe fatigue
-Failure of testing equipment
What is considered the most practical assessment tool for measuring body composition in the fitness setting, and why?
Skinfold measurements. Ease of administration and low cost.
Why is it extremely important that a trainer demonstrate strong skills and reliability when assessing body composition?
A body composition score can be critical to a client’s psyche or motivational levels.
Anthropometric measures include what?
Measurements of height, weight and/or circumference to assess body size or dimension.
When does the margin of error increase with skinfold measurements?
When the trainer is unfamiliar with identifying exact skinfold locations or lacks experience or technique in correctly grasping the skinfold site.
What is WHR?
Waist to hip ratio.
Name two common anthropometric measures that demonstrate strong correlations to health, morbidity and mortality.
BMI and WHR. These are only estimations.
What does body composition refer to?
The proportion of lean tissue to body fat tissue.
Lean body mass (LBM) is composed of:
- Muscles
- Connective tissue
- Bones
- Blood
- Nervous tissue
- Skin
- Organs
LBM means:
Lean body mass.
A certain amount of body fat is necessary for:
- Insulation and thermoregulation
- Hormone production
- Cushioning of vital organs
- Maintenance of certain body functions
