front 1
Physiological Importance of Warm-Up
| back 1 - nutrient+O2 rich blood to muscles // HR and Respiration Rate
(RR) [increase O2 demands]
|
front 2
Physiological Importance of Warm-Up
| back 2 -
= rate of force development (RFD) + peak contraction
velocities
|
front 3
Physiological Importance of Warm-Up
| back 3 -
= muscle viscoelasticity (based on specificity +
demands)
|
front 4
Physiological Importance of Warm-Up
| back 4 = metabolic reactions (cellular energy) |
front 5
Bohr Effect: as cellular metabolic activity increases
- decreases hemoglobin affinity for O2 = more efficient
offload oxygen
| back 5 → creates high concentration of hydrogen ions & CO2 → acidity |
front 6
Bohr Effect
- decreases hemoglobin affinity for O2 = ___
| back 6 = more efficient offload oxygen |
| back 7 - ⬆ body temperature // blood flow to muscles
- ⬇ DOMS //
injury risk
-
Priming the nervous system
-
Better + improved = ROM // performance
|
front 8
Cardiovascular Perspective | back 8 - steady-state = good sustained exercise/performance
- warm-up helps achieve this (early in exercise)
- EPOC =
excess post-exercise O2 consumption
|
| back 9 - warm-up should be specific to performance based on BF
|
front 10
Cool Down Important or Not..
- Quick cessations of intense exercise⇒
| back 10 - ⇒ rapid BP drop, and blood-pooling in lower extremities,
|
front 11
Cool Down Important or Not..
| back 11 - → period of low-impact following a more intense workout
provides gradual returns
|
front 12
Cool Down Important or Not...
- does not _____
- Acceraltes ____
| back 12 - attenuate the long-term adaptive response or prevent
injuries
- recovery of lactate, but not necessarily m.
tissue
