Q

Describe how the three energy systems contribute to muscular endurance

A

a. Phosphagen System (ATP-CP)
Duration: Lasts about 0-10 seconds.
Function: Provides immediate energy through the breakdown of adenosine triphosphate (ATP) and creatine phosphate (CP) stored in muscles.
Contribution to Endurance: While primarily used for short bursts of high-intensity effort, it supports quick recovery during rest periods in endurance activities.

b. Glycolytic System (Anaerobic)
Duration: Lasts about 10 seconds to 2 minutes.
Function: Generates ATP through the breakdown of glucose without oxygen. This process produces lactic acid as a byproduct.
Contribution to Endurance: It supports high-intensity efforts, allowing for sustained activity in events like sprinting or high-rep strength training.

c. Oxidative System (Aerobic)
Duration: Used for longer activities (more than 2 minutes).
Function: Generates ATP using oxygen to metabolize carbohydrates and fats.
Contribution to Endurance: This system is crucial for long-duration activities, as it provides a sustained energy supply, allowing for prolonged muscle contractions

Q

What is reactive strength vs explosive

A

Reactive strength is how fast once can change ebtween an eccentric and concetri movement and relies on SSC (Stength shortnig cycle) for exmapl squat and jump
explosve strength combines speed and strength and is how fast one can move thru ROM - rate of joint movement

ssc test - Measures the time taken to jump after a rapid downward movement (like a squat) to evaluate the efficiency of the stretch-shortening cycle.

RFD - orce Plate Measurements: Using a force plate during dynamic movements (like squat jumps) to assess how quickly force is developed at different points in the movement.

Olympic Lifts: Performance in exercises like the clean and jerk or snatch, where the speed and power of the lift reflect explosive strength.

125
Q

describe validity and relabilty vs practicality

A

lidity and reliability vs practicality
* It’s often a trade off which is true in multiple contexts
* The more accurate the test the less practical it is
* Tests that are more practical require attention to sources of error to maintain
robustness
For example….a push up test is very practical and requires little resources, but poor
execution will render it useless.
Compared to a cable tensiometer which is very robust and requires little
coaching/form/technique, however the equipment/technology needs means it’s not
practical for many
Take home point: ‘Field test’ can be robust and help achieve our goals of testing, but the
QEP must be aware of sources of error and work to mitigate them

eliminate sedentry behaviour becauase it puts us at risk as we get older of injury
peak strength occur in mid-lte twenties and declines after.

Improved athletic performance:

-endurance
-power
-speed
- agility

Reduces risk of injury, excessive fatigue, poor efficiency

Assessment of neuromuscular & musculoskeletal fitness provides information about client’s capacity to perform daily activities, cope with emergencies, avoid injury & disability and maintain functional independence as they age (CSEP, 2020)
