The 8 weeks of aerobic exercise training increased muscle fiber capillarization. However, this did not result in greater muscle fiber hypertrophy during the subsequent 12 weeks of resistance exercise training.

We divided healthy older males and females into two groups:
- 8 weeks aerobic exercise training —> 12 weeks resistance exercise training (AER group)
- 8 weeks no exercise control —> 12 weeks resistance exercise training (CON group)

Conclusion:
Cold-water immersion should be avoided during post-exercise recovery to ensure proper nutrient delivery to muscle tissue to maximize post-exercise muscle conditioning.

We used contrast-enhanced ultrasound to quantify muscle microvascular perfusion before and at multiple times after water immersion.
In addition, participants ingested an amino acid tracer to assess amino acid incorporation into muscle tissue during recovery.

We used a within subject design wherein one leg was submerged in cold water (8 degr) while the other leg was submerged in thermoneutral water (30 degr) for 20 min. Before water immersion, participants completed a bout of resistance exercise for the lower body.
