Midterm Part 1 Flashcards
Differences between RPE and HR
RPE: Subjective, includes mechanical component of performance, “calibrated” relative to GXT, rating is made up of EVERYTHING athlete is experiencing (performance/non performance)
HR: NOT subjective, limited to metabolic component of performance, can act as a surrogate for VO2, can be affected by many things
What factors may contribute to High HR?
^central command = ^ sympathetic system
^ aerobic demand for resythn of ATP-PCr
^ O2 demand
^thermoregulation
VO2 max Intervals were @ what %? And what was this percentage of specifically?
(Short)30/30 = 100%/30-40% (Long)2m/5m = 85-100%/30-40% Percentage = VO2 Power Out
What is the point of VO2 intervals? How many times per week should VO2 intervals be done?
- Overload aerobic metabolism: Cannot supply enough O2
- Maximize stress to mechanical (movement) requirements
- 2-3 per week
During VO2 intervals who would be placed at the 85% of max? Why would they be there?
85% would be the “normal people” not elite athletes. This is because the VO2 Slow component (fast twitch) will slowly become more utilized in less trained individuals, this will cause a slow rise in O2 usage thus VO2 utilization. Essentially 85% will turn into 100%
Why 30/30 for short intervals?
- Spare glycogen and utilize fat better:
1. PCr system cover’s O2 deficit instead of glycolysis
2. Utilize O2 bound to myoglobin
What are the 3 factors of performance?
- VO2 max
- Factional Utilization
- Economy
How does LSD training overload the athlete and what part of the body does it work on (peripheral/central)? What about VO2 Max training?
LSD (50-70%) - Overload via Duration. Peripheral.
VO2 (100%) - Overload via intensity. Central.
