Midterm Part 2

Question 1

Define “Endurance” (2)

Answer 1

• Ability to sustain a steady power output for a long time

- the ability to repeat brief exertions of near maximal effort

Question 2

How can performance be expressed?

Answer 2

Force, speed, power, work, movement

Question 3

What are the two main considerations in training and conditioning?

Answer 3

Metabolic: Energy systems (engine)
Mechanical: Neuromuscular (chassis and wheels)

Question 4

Do physiological responses (VO2/HR) match similarly to exercise intensities(PO, Speed) in both trained and untrained people?

Answer 4

Nope

Question 5

Describe Aerobic Threshold(5)

Answer 5

• Mostly aerobic, but not solely.
• Low PO compared to other systems
• Made for Long duration
• Below VO2 Max
• Continuous Activity (45 min)

Question 6

VO2 max is a combination of what energy systems?

Answer 6

Both Anaerobic and Aerobic

Question 7

Describe Good Cycling Technique/Position (5)

Answer 7

• Leg extension@ 97%
• Knee Cap over pedal spinal when @ 3 O’clock
• 45 degree angle of torso
• “Scrape mud off your shoe” at bottom of the pedal stroke
• “Cycle through it”

Question 8

Describe Good Running technique/position (6)

Answer 8

• Good running is reactive (stretch shortening cycle)
• Elbows at 90 degrees or less and never cross centre of body
• “Shorten Contact time”
• Foot contact under centre of gravity
• Requires torso activation
• Back leg swing = passive movement

Question 9

According to Billat(2001) how does Short VO2 max intervals spare glycogen and utilize fat better? But what is crucial to make sure this happens(role of recovery)?

Answer 9

• Lets the PCr system cover the O2 deficit (instead of glycolysis
• Utilizes O2 bound to myoglobin
• NEED enough recovery time to allow these two factors to recover (30 sec minimum)
