Section 4 Flashcards
(77 cards)
Deconditioned
State of lose physical fitness, including muscle imbalances, decreased flexibility and a lack of core and joint stability
General purpose of preexercise assessment
Collect baseline data
PAR-Q+ health indicators
Current level of physical activity
Signs or symptoms of cardio, pulmonary, renal or metabolic disease
Desired intensity
PAR-Q+ designed for
MINIMUM SCREENING TOOL
For low to moderate intensity, minimal pre exercise screen for HRA
HHQ
Questionnaire for health history and habits, such as exercise history, eating behaviors and general lifestyle
Ankle sprains effect on body
Decrease muscle activation if the gluteus medius and max. Poor control of lower extremities
Effects of Knee injuries involving ligaments
Decreased activation to muscles that stabilize patella
Effects of low back injuries
Decreased activation of muscles that stabilize the core, resulting in poor stabilization of spine
Effects of shoulder injuries
Altered muscle activation of the rotator cuff, can lead to instability of shoulder joint
Fitness assessment rationale/considerations (list 4)
- Relevance - must apply to clients specific goals and needs and abilities
- Appropriateness - may be demotivating
- Validity - do tests measure what you want?
- Reliability - do tests produce consistent and repeatable results
Peripheral vasodilation
Thermoregulation process to cool the body during exercise - blood vessels near skin will expand
Exercise test termination criteria
- Chest pain
- Drop in systolic BP below reservist measurement by more than 10 mmHg during any increase in exercise intensity
- SBP > 250 or DBP > 115
- Sharp leg pain or cramping
- Increased uncoordinated movements
SBP
Systolic blood pressure. Top number. Greatest pressure during the cardiac cycle. Force of blood pushing against arterial walls
DBP
Diastolic - bottom number. Lowest pressure of cardiac cycle. Remaining force generated by the blood in arteries while heart is relaxed
Stage 1 hypertension BP and recommendation
130-139/80-89
Lifestyle changes and medical monitoring
Stage 2 Hypertension
140+/90+
Lifestyle changes and medical monitoring and MEDS
Hypertensive crisis
180+/120+
Anthropometry
Study for understanding physical variation in size weight and proportion
Ex: BMI and circumference measurements
Healthy body fat% in men and women
Men - 10-20%
Women - 20-30%
Jackson and Pollock Seven Site Protocol
SKF method to calculate body density. Use online calculator. Same locations M vs F
Most accurate but most invasive to client. Best for clinical or athletic pops
Tricep
Chest
Subscapular
Midaxillary
Suprailiac
Abdominal
Thigh
J and P three site protocol
Determine body comp in healthy pops.
Men - chest abdomen thigh
Women- triceps suprailiac thigh
Less accurate as 7-site but valid and less invasive
Four site durnin-womersley protocol
Alternative to Jackson and Pollock. Four site measurement.
Biceps triceps subscapular and suprailiac
Best for ages 17-49, only requires upper body (no shorts needed for thigh measurement)
Bioethical impedance analysis - fast vs slow and why?
Fast = leaner
Slow = higher body fat
Lean = more water content = less resistance = fast conduction
Hydrostatic underwater weighing
More lean = more dense
Archimedes principle - Buoyancy
Not practical outside of lab but very accurate
