Effect of prior weight training on aerobic exercise fat oxidation

A small group of men performed 3 types of exercise training:

1. Aerobic training only.
2. Weight training followed by aerobic training with a 20 minute rest period in between.
3. Weight training followed by aerobic training with a 2 hour rest period.

When the group performed aerobic training 20 minutes after resistance training, higher fat oxidation rates where achieved.

The 2 hour rest period may have been too long as norepinephrine and growth hormone levels were already retreating. Free fatty acids were still elevated, probably indicating that insulin sensitivity declining too.
