Acute concentration of hydroxyproline in different methods for strength training

This research was designed to measure the levels of 01hydroxyproline (HP) in urine alter the application of two different methods of strength training. Thirty fit, healthy men were randomly divided into two groups: exercise (EG) and control (CG). 80th groups provided urine samples prior to training, although only the EG performed 1 repetition maximum (RM); 5RM and 30RM tests. After this, the EG performed three series of 5RM. Alter two hours, urine samples were collected from the EG. Sixteen days later, the same pl;.procedure took place using a 30RM protocol. The HP levels in urine were quantified colorimetrically using a spectrophotometer. Statistically significant differences in HP values were found only for the 5RM training method (e. = -22%, P< 0.05). It was concluded that damage to the conjunctive tissue only too k place with 5RM training, thus confirming that one way 01 avoiding stagnation in the adaptation 01 subjects with certain experience 01 strength training is to use more intense methods. However, in such training protocols, the recovery time between sessions should be greater due to the resulting increase in tissue damage.
