Factors Affecting Performance

Question 1

ATP - PC Energy System
( NO o2)

Answer 1

We make it from phosphate creatine, stored in our muscles

We initially start with the stored ATP and then after one explosive movement, we are left with ADP which is useless.

The phosphate creatine shoots off and joins ADP to make a new ATP molecule

Fuel source: phosphate creatine specifically the P joining the ADP to make ATP (energy)

Used for: highly explosive sports - sprinting, throwing, jumping

Intensity: over 95%

PC only lasts in muscles for 10 seconds

No waste products, only HEAT

Takes 2 mins to recover (during rest)

The recovery is the PC being stored back in the muscles

Question 2

Lactic acid - Anaerobic Glycolysis
(No o2)

Answer 2

1 glucose molecule = 2ATP + pyruvic acid

Because No oxygen - pyruvic acid is changed into lactic acid

Fuel source = glucose with no o2

Waste product: lactic acid

Recovery = 2 hours but SPEEDS up with active recovery to dissipate lactic acid

Used for: 400m running race, 30 shot rally in tennis etc

Lasts for: max of 2 minutes

Intensity: 85%-95%

Question 3

Aerobic System - Aerobic Glycolysis
(HAS o2)

Answer 3

1 glucose molecule = 2ATP + pyruvic acid

Because of oxygen - pyruvic is changed into the KREB CYCLE ( Co2, h2o and 36 ATP)

Fuel source = glucose with oxygen

Waste product = H2O and Co2

Recovery = 24-48 hours because you need to eat to refuel

Used for: marathon or triathlon (something that lasts from 2 minutes until all fuel exhausted

Intensity: below 85%
