AIM. The aim of this work was to analyze lower and upper limb strength in a group of weightlifters with or without the chronic use of the bite during weightlifting exercises and training. METHODS. Twenty male athletes, divided into two groups, were studied. The first group (GB) included thirteen male weightlifters (age: 27±5 years, weight: 78±7 kg, and height: 176±4 cm, mean±SD) who continuously used a bite for eight weeks of training. The control group (GC) included 11 athletes (28±6 years, 78±11 kg weight, 175±6 cm height) who normally trained without a bite. The bites were made after the axiographical registration to check for temporomandibular joint movement using the Cadiax® Compact diagnostic instrument (Gamma Dental, Austria) and mounted in centric occlusion (natural closed position). The contact of the teeth was monitored through the T-Scan III (Tekscan, USA). The strength tests did not require any training phase since they were normally included in the athletes routines. Strength exercises were: Bench press, Lat machine, Curl bar, Overhead press, Push down, and Squat. The athletes were evaluated before and after the eight week period of training. RESULTS AND DISCUSSION. No acute strength variations were found at the beginning between GB and GNB (the same subjects tested also without bite, non parametric Wilcoxon test) and also between GB and GC or GNB and GC (non parametric Mann-Whitney U-test). On the contrary, strength values were always found increased at the end of the study (Wilcoxon test), but the GB showed the greatest variation (44%, p<0,001). The other average percentage increases were: 37% in GNB (P<0,001) and 31% in GC (P<0,001). This findings allow to conclude that the use of bite did not introduce acute variations in force production but allows to add further increase to the physiological variation induced by exercise and training.

Abstract
AIM. The aim of this work was to analyze lower and upper limb strength in a group of weightlifters with or without the chronic use of the bite during weightlifting exercises and training. METHODS. Twenty male athletes, divided into two groups, were studied. The first group (GB) included thirteen male weightlifters (age: 27±5 years, weight: 78±7 kg, and height: 176±4 cm, mean±SD) who continuously used a bite for eight weeks of training. The control group (GC) included 11 athletes (28±6 years, 78±11 kg weight, 175±6 cm height) who normally trained without a bite. The bites were made after the axiographical registration to check for temporomandibular joint movement using the Cadiax® Compact diagnostic instrument (Gamma Dental, Austria) and mounted in centric occlusion (natural closed position). The contact of the teeth was monitored through the T-Scan III (Tekscan, USA). The strength tests did not require any training phase since they were normally included in the athletes routines. Strength exercises were: Bench press, Lat machine, Curl bar, Overhead press, Push down, and Squat. The athletes were evaluated before and after the eight week period of training. RESULTS AND DISCUSSION. No acute strength variations were found at the beginning between GB and GNB (the same subjects tested also without bite, non parametric Wilcoxon test) and also between GB and GC or GNB and GC (non parametric Mann-Whitney U-test). On the contrary, strength values were always found increased at the end of the study (Wilcoxon test), but the GB showed the greatest variation (44%, p<0,001). The other average percentage increases were: 37% in GNB (P<0,001) and 31% in GC (P<0,001). This findings allow to conclude that the use of bite did not introduce acute variations in force production but allows to add further increase to the physiological variation induced by exercise and training.
