There are two components of the FaCT test protocol:
A: The Performance Line (step test) is used to evaluate physiologic changes over time. Using the FaCT software, one can easily see how an athlete has improved, and how to adjust their training program to adapt to these changes. The performance line can also be used to determine whether a particular training program has been ineffective, and allow an athlete to make appropriate changes to address the problem.
B: The LBP (lactate balance point) is the determination of the body’s ability to balance the production of lactate in working muscles with the clearance by the body.
During the test I do the following :-
1. Using the hear rate variability function on the Polar to determine your recovery zone.
2. Record oxygen saturation and breathing rate to determine your cross over point for Basic Intenisty Slow Twitch Fibre/Basic Intenisty Fast Twitch Fibre zone (not always possible as humans aren't perfect).
3. Record watts for your performance will not take you to breaking point.
4. Record your recovery line.
5. Record your breathing pattern.
6. Find your Lactate Balance Point.
7. Record body temp.
8. Record activity level.
9. Try and identify weaknesses.
