The efficiency of weightlifting belts is definitely subject to controversies, and opinions about safety remain very divided. One main problem is that weightlifting belts allow athletes to lift more than they should. Another criticism against belts is that they back muscles responsible for body stability and the gripping muscles of the forearms don’t get the same stimulation and lose during training. In some other people’s opinion, weightlifting belts prevent health problems associated with training and increase the body stability. Normally, they prevent injuries to the back and the spinal cord by taking over some of the pressure.
Pros claim that it’s a good habit to wear weightlifting belts particularly in competitions, although the equipment is widely available and used by amateurs too. The belt keeps the spine in a good posture while lifting the weights and the soft tissues remain protected, nevertheless, a problem may appear with extensive usage. The long term and short term impact of wearing weightlifting belts is pretty serious. These equipment items can increase the intra-abdominal pressure beyond accepted levels. Yes, the intestinal muscles are indeed protected against injuries, but you could develop hypertension because of the tightness of the belt.
The weightlifting belts are available in various designs, allowing adjustments to the pressure level and the body height. When manufactured for power training, weightlifting belts incorporate special features for superior protection. Usually made of leather, such belts are braced by neoprene. The belt model should be chosen according to physiognomy criteria and training objectives. Padded or non-padded cotton and nylon items are also widely available. The sizes on the other hand range from XS and S to XL and XXL.
Other than back protection, leather weightlifting belts have no other contribution to the athletic performance. And despite the common belief of improved training, studies debunk this myth. Studies conducted at the Albany Medical Center, N.Y., reported almost no difference between the group of weightlifters who wore belts and the group who didn’t. Even without the much emphasized back protection provided by the belt, the back muscles have better chances of developing and increasing in strength. Even so, wearing weightlifting belts helps amateurs a lot, on the one condition that they not be worn extensively.
