5. Components of Fitness & Fitness Testing Flashcards
Health definition
a state of complete physical, mental and social wellbeing, not merely the absence of disease or infirmity
Fitness definition
the ability to cope with everyday life / meet the demands of the environment
What are the 6 health related components?
-flexibility
-power
-strength
-cardiovascular endurance/aerobic capacity
-muscular endurance
-speed
What are the 6 skill related components?
-agility
-coordination
-balance
-reaction time
-speed
Aerobic capacity/cardiovascular definition
the ability of the cardiovascular and respiratory systems to deliver oxygen to the working muscles during sustained physical activity
VO2 max definiton
the maximum amount of oxygen that can be taken into the body and untilised per minute (ml/kg/min)
example for cardiovascular endurance
marathon runner maintaining pace over 26.2 miles
field test for CV endurance
multistage fitness test, 12 minute Cooper run
lab test for CV endurance
VO2 max test using treadmill or cycle ergometer (gas analysis)
muscular strength definiton
the maximum force a muscle can generate against a given resistance in a single maximum contraction
example of muscular endurance
during a rugby scrum, players in the forward pack, particularly in the front row (props and hookers) use their muscular strength to push against the opposing team’s pack
field test for muscular endurance
1 rep max, hand grip dynamometer
lab test for muscular strength
force plates to measure peak force during isometric contraction (IMTP)
4 types of muscular strength
-reactive
-static
-dynamic
-isokinetic
reactive strength definition
ability to rapidly change between concentric and eccentric contraction
example of reactive strength
basketball player rebounding after landing a jump to immediately do another
reactive strength index formula
jump height/flight time
dynamic strength definition
ability to exert force continuously over time
example of dynamic strength
rowing - arms pulling oars through water repeatedly
static strength definition
ability to exert force without muscle changing length (isometric contraction)
example of static strength
gymnast holding crucifix on rings
isokinetic strength definition
ability to exert force at a constant speed through a full range of motion
example of isokinetic strength
rehab settings - assessed with machines to see if muscle works maximally at every point of motion
muscular endurance definition
ability of a muscle to sustain repeated contractions or maintain a static contraction over time whilst withstanding fatigue
example of muscular endurance
a rower pulling through each stroke over a 2000m race, using upper and lower body muscles, at a constant high velocity
field test for muscular endurance
press up/sit up test for 1 minute
lab test for muscular endurance
30 second wingate test
flexibility definition
the maximum elasticity of muscles, range of motion at a joint
static flexibility definition
range of motion around a joint when the body is in a stationary position
example of static felxibilty
around hips when gymnast holds a split on the floor
dynamic flexibility definition
range of motion around a joint during movement involving muscles and soft tissues moving through their full range actively
example of dynamic flexibility
gymnast performing a split leap in the air
field test for flexibility
sit and reach test
lab test for flexibility
goniometry to measure specific joint angles
power definition
ability to exert maximum force in the shortest possible time (an explosive movement)
power formula
strength x speed
example of power
hammer throw - athlete must use lower body strength to drive turns, core power to maintain rotational speed and upper body power to release hammer with maximal force and speed
field test for power
vertical jump, standing broad jump
lab test for power
force plate analysis during jump, 6 second peak power test, 30 second wingate test
body composition definition
proportion of fat, muscle, bone and other tissues that make up an individual’s body
field tests for body composition
-skinfold callipers
-body mass index (BMI)
-waist to hip ratio
-bioelectrical impedance analysis (BIA)
lab tests for body composition
-hydrostatic weighing (underwater)
-dual energy x-ray absorptiometry (DEXA)
skinfold callipers method
measures thickness of subcutaneous fat at specific sites of body
