Making weight: a case study of two elite wrestlers

Area of Science:

• Sports Science
• Exercise Physiology
• Combat Sports Nutrition

Background:

• Elite athletes often need to manage body weight for competition.
• Sambo wrestlers, in particular, face demands for both strength and endurance.
• The impact of weight loss on performance metrics in Sambo is not fully understood.

Purpose of the Study:

• To investigate the effects of a hypocaloric diet and intensive training on elite Sambo wrestlers.
• To assess changes in maximal oxygen uptake, anaerobic threshold, isometric strength, isometric endurance, and sprinting ability.
• To determine if performance characteristics can be maintained during a weight reduction phase.

Main Methods:

• Two elite Sambo wrestlers participated in a 22-day pre-championship training and weight-loss program.
• Athletes followed a hypocaloric diet combined with intensive training.
• Key performance indicators including maximal oxygen uptake, anaerobic threshold, isometric strength, isometric endurance, and sprinting ability were measured.

Main Results:

• Athletes lost approximately 8% of their initial body weight.
• Maximal oxygen uptake, anaerobic threshold, and maximum isometric strength were maintained or improved relative to body weight.
• Isometric endurance and short-term sprinting ability decreased by up to 7% and 13% respectively.

Conclusions:

• A well-planned weight reduction program combined with intensive training can preserve aerobic power and isometric strength in elite Sambo wrestlers.
• Prolonged anaerobic exercise performance, including sprinting, may be negatively affected by significant weight loss.
• Athletes and coaches should consider the trade-offs between weight reduction and specific performance decrements.
