Effects of Circuit Resistance Training and Timely Protein Supplementation on Exercise-Induced Fat Oxidation in Tetraplegic Adults

This study investigates how circuit resistance training (CRT) and protein supplementation (PS) affect fat usage during exercise in people with tetraplegia. Participants did CRT for 6 months, with some getting protein right before/after exercise (iPS) and others getting it 24 hours later (dPS). The goal was to see if this training, combined with protein timing, would help them burn more fat during exercise. The researchers measured how much fat and carbohydrates the participants burned during exercise tests at different points in the 6 month CRT program. They compared the two protein supplementation groups to see if timing of protein intake made a difference in how much fat was burned. The study found that circuit resistance training did not significantly increase fat oxidation in persons with tetraplegia, regardless of whether they took protein supplements immediately before and after exercise or 24 hours later. The fat oxidation levels remained low even after the training intervention.

• 1
  Maximal absolute fat oxidation did not change significantly from 0 to 6 months of circuit resistance training.
• 2
  Fat oxidation remained low never exceeding an average of 0.10 ± 0.09 g/min for any given exercise intensity.
• 3
  Differences in changes in substrate utilization between the protein supplementation groups were not significant.
