Anaerobic Capacity Essential for High-Level Boxers

A new study underlined need for acid buffering capacity and tolerance of acidosis in elite boxers.

Understanding the needs of combat athletes can be a difficult task. A recent study in the Journal of Strength and Conditioning Research tested the acid-base balance, an important aspect of fatigue, for the first time in a group of elite boxers.

What the research says:

  • World-champion boxers had the highest levels of acidosis and blood lactate concentration.
  • Researchers suggested athletes train to increase anaerobic fitness and buffering capacity.

Study Design

Three teams of boxers, each team having one boxer in each weight category, competed on two different occasions. There were 28 boxers total. Team A competed against both Team B and Team C, separated by four months.

All the subjects were elite boxers from three national teams. They were chosen as the best from their respective countries. In fact, six of the 28 boxers had won world titles (either world championship or Olympic medals).

For teams A and C, the researchers collected data for five different factors:

  • Mean blood lactate concentration
  • Bicarbonate concentration
  • Hemoglobin O2 saturation
  • Partial pressure for CO2
  • pH levels

These values represented work performed, the resulting acid byproducts from fatigue, and the buffering ability of the body. The researchers also took punch counts for the final rounds.

Results

The boxers achieved a moderate level of blood lactate and acidosis. This means there was a substantial contribution from anaerobic energy sources, which may be a limiting factor for performance. Blood lactate levels were highest in the middle-weight classes (average weight was about 140lb).

As the researchers noted, there was also a difference in the world-champion boxers:

It is of note that the three boxers who presented the greatest mean blood lactate concentration and acidosis in comparison to others were previous world champions, suggesting that the best world-class boxers are able to achieve a high physical intensity during the three rounds and support a high level of acidosis.

Interestingly, when team A competed against and defeated team C, there was a significant difference in the markers of acid and fatigue between the two groups. This difference may have been a contributing factor to the victory of team A. However, the researchers noted other factors as simple as a difference in mouth guards could have also contributed.

Considerations

In order to perform well in boxing, an athlete must have a broad range of physical attributes. This study underlined need for acid buffering capacity and tolerance of acidosis.

However, that’s not to say aerobic conditioning is unimportant for combat athletes. The researchers noted previous investigations have shown trained boxers to be in good aerobic shape. The researchers explained no one has performed a complete analysis of the aerobic needs of boxers because, quite simply, it isn’t possible. Anaerobic contribution to performance, on the other hand, is much easier to quantify and measure.

As demonstrated in this study, training that improves the ability to buffer acid can be beneficial for boxers. Buffering capactiy is particularly important toward the end of rounds when activity levels increase. But don’t skimp on the aerobic work, either.

About Doug Dupont

Having grown up at the foot of a forest covered mountain in rural Vermont, Doug was active from a very young age. Hiking, running, and climbing were a part of everyday life in the Green Mountains. This culture of exercise led to dabbling in martial arts as a teen, and also getting work in a local powerlifting focused gym. Doug continued to pursue knowledge and training in exercise, becoming a certified personal trainer while still a teenager. Once in college he began his hand at the business side of fitness, taking a management position at a large local gym. During that time he became a founding member of the UVM Brazilian Jiu Jitsu club, and was the first among their competition team. After only a few months he was assisting in coaching, and ran conditioning program for the club.

Out of college Doug set up his own training center. He grew his list of clientele including several professional MMA athletes, eventually going so far as to corner a world title fight. He has continued ­­­to develop his business into today.
