Resumen
El texto original del estudio, en el idioma en que se publicó.
Study design
Double-blind, placebo-controlled, randomly assigned, crossover.
Objective
To assess the influence of a short-term oral creatine supplementation on 800 m wheelchair performance.
Setting
Swiss Paraplegic Centre, Nottwil, Switzerland.
Subjects
In total, six (four male, two female subjects) competitive wheelchair athletes participated in the study. Their age was 33.0+/-9.1 years, height 171.5+/-7.7 cm and weight 63.1+/-6.2 kg. Average weekly training volume was 10.0+/-3.7 h. All of them have been engaged in regular training for over 10.5+/-7.2 years.
Methods
During the two treatment periods, subjects ingested 4 x 5 g of creatine monohydrate or placebo (maltodextrin) daily during 6 days in a randomised order. A washout period of 4 weeks lay in-between the two supplementation periods. Before and after each treatment period athletes performed an all-out 800 m wheelchair test on a training roller. Time to complete 800 m, rate of perceived exertion (RPE), lactate concentrations and heart rate were measured. Before each test, body weight was determined.
Results
Times to complete 800 m before and after creatine supplementation (102.8+/-13.9 versus 100.5+/-11.3 s) compared to before and after placebo supplementation (101.6+/-15.6 versus 99.5+/-13.8 s) were not significantly different. Moreover, for all other parameters measured, no significant differences between creatine and placebo supplementation were found.
Conclusion
A short-term oral creatine supplementation compared to placebo seems not to enhance performance over 800 m in trained, spinal cord-injured, wheelchair athletes.
