BRIEF REVIEW: RELATIONSHIP BETWEEN NUTRITION EDUCATION AND RAPID WEIGHT LOSS

B

Cutting weight safely is a critical element of performance and health in combat sports. It is often thought that athletes who are better educated in the science and practice are both able to cut weight more safely and with less impact on their performance, and also keep their weight closer to the division limits and therefore reduce the amount that they have to cut. 

 

This authors of this study took 63 English male amateur boxers and had them fill out the Nutritional Knowledge Questionnaire for Athletes (NKQA) and the Rapid Weight Loss Patterns Questionnaire (RWL-Q), which assesses the frequency with which specific weight loss techniques are utilised as well as the extent to which knowledge and guidance are sought from professionals. The results of the two questionnaires were cross-referenced to establish correlations. 

 

Contrary to the author’s hypothesis, the study found no correlation between NKQA and RWL-Q scores, suggesting that having a greater understanding of nutrition basics made no difference to the amount of weight athletes cut before a fight and the severity of the methods used. 

 

It is likely that the NKQA was to generalised a measure for the specific athlete population and information related to the benefits, downsides and risks of rapid weight loss are of more relevance.

 

This paper highlights the importance of continuing to push for greater awareness and education around rapid weight loss in combat athletes.
