Maximizing Weight Cutting Strategy to Enhance Performance

Canadian Sport Institute Calgary (CSI Calgary) Performance Dietitian Kelly Drager has been leading her field through an innovative project with members of the Canadian Wrestling Team. The project has been funded through Innovations 4 Gold (I4G), an applied sport research program led by Own The Podium.

Drager and CSI Calgary Strength and Conditioning Coach Mac Read, with help from Research and Innovation Lead Erik Groves, have been gathering information to determine an ideal way for wrestlers to lose weight for competition weigh-ins, while minimizing the impact that it has on their performance. The data set that has been collected so far is from three different competitions (Pan-American Championships, PanAm Games, and World Championships) and according to Drager, could have a significant impact on performance and provide “progress for the sport.”

Their research aims to give athletes a performance plan that they can use to take the guesswork out of cutting weight. This should reduce stress on weigh-ins and thus place more emphasis on performance. Of the results, Drager says, “We are now starting to see trends within weight categories. It is beneficial to have a bandwidth for each weight category, creating specific guidelines.”

The team has tracked athletes’ weight and urine specific gravity (level of hydration) during weight cutting. The data shows how they rebound from weigh-ins to competition time. These weight cutting curves can help athletes use consistent, predictable plans at major events. Currently, Read and Drager are observing what is happening during regular training. By monitoring the athletes’ heart rate, rate of perceived exertion, weight, and urine specific gravity, they are able to identify what is normal during training weeks.

This project is particularly exciting because as Drager says, “It is very applicable to other weight category sports such as judo. Preparing these athletes for enhanced performance is the goal.”

Long-term, this project will also be useful to developmental athletes who will be able to recognize that performance, not weight cutting, is the main goal of the sport. For younger athletes, Drager wants to promote “better health, growth and bone development.”

Ultimately, this data set will help Canada’s top wrestlers have stronger performances on the international stage. However, more importantly, Drager emphasizes that it “is going to help ensure better development and health of athletes.”
