Hyp levels in adults submitted to dynamic stretch in liquid medium and ground medium

Abstract

Collagen catabolism in the locomotion system implies liberation of an increased hydroxyproline (HYP) level in winary excretion, which in turn constitutes a biochemical marker indicating damage in the conjunctive tissue. The objective of the present study was to verify the locomotion systems collagen catabolism degree through the HYP level excreted in 10 (ten) non – athletes adults men’s wire, with age group between 24 to 45, submitted to dynamic stretch in liquid medium or ground medium. Four movements limited by both muscular elasticity and joint mobility were selected for dynamic stretch performance and three urine sample collections were used in laboratory. As a methodological procedure sample collection was carried out for a two hour period (2:00) post hydration, and taken to the laboratory within 3 (three) hours. The HPLC – system liquid chromatographic determination of total hydroxyproline in urine – was used with reference value of 15 – 43 mg/d (Cherneeky et al., 1993). The fi rst collection was carried out 24 hours before the dynamic stretch to verify the basal level of HYP as sample group reference of volunteers. The second and the third collections were carried out 24 hours after the dynamic stretch was accomplished in both means. The results found for HYP levels (for p= 0.05) were for the basal level 39.07 + 15.27; for the levels 24 hours post – ground training were 71.28 + 12.15 and for the levels 24 hours post-water training were 66.74 + 10.31. From the results it is concluded that there is difference between the basal instants and the 24 hour post – training, indicating therefore the occurrence of damage of the conjunctive tissue. The direct analysis among the environments didn’t present a signifi cant difference (for p < 0.05). In spite of the occurrence of damage in both means with the results obtains, it isn’t possible to conclude which mean can prevail for the training with lesser risk of damage.
