Brief Summary
A positive ergogenic effect of sodium citrate and caffeine ingestion in a short-term, high-intensity exercise task was shown by several studies. These studies were conducted with healthy, able-bodied subjects. The aim of the study is to investigate whether caffeine or sodium citrate ingestion could enhance performance in spinal cord injured wheelchair athletes. It is a double blind, placebo controlled and randomized study.
