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