(40 cards)
define physical fitness
“Organic systems of the body are healthy and function efficiently so as to resist disease, to enable the person to engage in vigorous tasks and leisure activities, and to handle situations of emergency.”
what are some benefits of regular physical activity
- improved cardiorespritory fitness
- reduced cancer risk
- improved bone mass
- improved weight control
-prevention of diabetes - improved immunity
- improved mental health and management
- longer lifespan
what are the five components of physical fitness
- cardiorespritory endurance
- muscular strength
- muscular endurance
- flexibility
- body composition
define cardiorespritory endurance
The ability of the cardiorespiratory systems to process and transport oxygen required by muscles cells, possibly over long period of time.
define aerobic activities
body metabolizes oxygen into inspired oxygen
activities of long duration
activities of low intensity
(marathons, hockey games etc.)
define anaerobic activities
body produces energy, but without the use of inspired oxygen
short duration, high intensity
(sprinting)
define oxygen debt
an insufficient amount of oxygen required for an activity
(sucking wind and nothings working)
define muscular strength
Ability to contract skeletal muscles for work
The force that a muscle can exert
good muscle strength
better able to contract
better able to maintain sufficient force to complete tasks
define muscular endurance
the ability of the muscle or muscle groups to function over time
requires that the body to have a sufficient level of oxygen and nutrients
Muscle strength does not equal muscle endurance
Strength does not equal endurance
Ex. Powerlifters have strength not endurance
define flexibility
the ability of the joints to move through a range of motion (ROM)
Differs between joints
use / disuse will affect ROM
define body composition
the percentage of muscle, bone, fat that collectively make up the body
what are the necessary components to a exercise program
cardiorespiratory endurance exercise (run, cycles, HIIT)
muscular strength and endurance (weightlifting/ strength training)
flexibility exercise (yoga)
skill training
what is the list of least to more germs gym equipment
- elliptical
- dumbbell
- barbell
- Yoga ball
- Yoga mat
how much water should you be drinking before and after an exercise

assess your fitness
prevent and manage athletic injuries, give them rest, don’t push it
stay with your program
what care is required for soft tissue injuries
rest, ice, compression and elevation
what does cold plunging do

After endurance- can help recover muscles
Benefits of cold plunging comes from the deep breathing (meditation technique)
what are the risks to cold plunging
can put you into fight or flight mode
