Anaerobic Endurance for Weightlifting: Why It Matters More Than Aerobic Conditioning

Understanding Conditioning for Weightlifters

In the current “fitness” environment, there appears to be some confusion about the concept of conditioning or endurance. This is especially true for the training of weightlifters. What many individuals consider excellent endurance conditioning is not especially effective for weightlifters. The endurance demands for weightlifting training differ considerably from commonly accepted concepts of physical endurance.

Aerobic vs Anaerobic Endurance Explained

What needs to be conceptualized appropriately is the physiological difference between aerobic endurance and anaerobic endurance. In aerobic endurance events, oxygen is supplied to the muscles at the same rate that it is metabolized. In anaerobic events, the oxygen is metabolized faster than it can be provided, hence the term oxygen debt.

Long-distance running is an aerobic endurance event. For this reason, it is possible for television announcers to conduct interviews with marathon winners as soon as the event concludes, not so much after an 800-meter race, which is an anaerobic event.

Why Weightlifting Relies on Anaerobic Capacity

Training for weightlifting is an anaerobic activity. A set uses oxygen faster than it can be supplied to the muscles. At the conclusion of a set of, say, heavy cleans, the body is in oxygen debt, which means heavy breathing. Once the respiration rate returns to close to normal, the body has recovered, and the next set can commence.

Factors That Determine Anaerobic Fitness in Weightlifting

As an example, let’s say that a lifter is programmed to perform 3 sets of 3 reps with 80% in the clean. In order to determine the lifter’s fitness for this training, attention should be paid to the following factors:

The amount of rest time between reps. Lifters who are not in condition to perform this training will take an inordinate amount of time between reps. They might spend time adjusting and tightening the plates, chalking up, and rebuckling their belt. All of this is being done in order to provide more oxygen. The rest time between the second and third reps will exceed the rest time between the first and second reps. The third rep of the third set may well be a failure.
The amount of rest time between sets. This is why I do not favor one lifter to a training platform if at all possible. Three lifters of the same gender lifting weights within the same approximate ranges on one platform will force the more poorly conditioned lifters to shorten the rest time between sets. In no case should a lifter have to take a rest between sets longer than 3:30.
The smaller the athlete, the shorter the rest time. The younger the athlete, with all other factors being the same, the shorter the rest time.

Sometimes it can be helpful to have a smaller lifter share a platform with a larger lifter in order to improve the anaerobic endurance of the larger one.

The Competitive Advantage of Anaerobic Conditioning

This emphasis on improving the anaerobic conditioning of a weightlifter will prove to be helpful when the athlete is the last lifter in a session and must follow him or herself in the final attempts of the clean & jerk. A lifter who is in poor condition will not be sufficiently recovered to put forth the maximal effort needed to make a competition-winning clean & jerk in a significant competition. Those of you who are coaching larger and/or older athletes should keep this factor in mind.
