Abstract Objective To analyze the effect of high-intensity training on striated muscle and vital organs in recruits and to evaluate the intervention effect of hydration and alkalization of urine. Methods In this study, 500 recruits from a certain troop were selected and randomly divided into a conventional training group and a high-intensity training group. Effects of high-intensity training on striated muscle and important organs of the recruits and its intervention effect 4 weeks after training, blood biochemistry and electrocardiogram were collected for statistical analysis. The high-intensity training group was given periodic hydration, sodium bicarbonate tablet 1.5 g/day alkalized urine intervention treatment, , and the changes of biochemical indexes before and after intervention were observed. Results The rates of striated muscle injury (6.67% vs. 16.38%), rhabdomyolysis (0.00% vs. 2.59%), myocardial injury (0.00% vs. 7.76%), liver injury (7.50% vs. 29.31%), kidney injury (3.33% vs. 9.48%) and inflammatory response (19.17% vs. 43.10%) were compared between the two groups. We compared the incidence rate of sinus bradycardia (2.50% vs. 6.90%), sinus tachycardia (0.83% vs. 6.03%), left ventricular high voltage (2.50% vs. 7.76%), and short PR interval (0.00% vs. 2.59%). All the indexes of the high-intensity training group were significantly higher than those of the conventional training group, and the differences were statistically significant (P<0.05).In addition, we compared the changes of biochemical measures before and after the intervention, such as mean of Cr (80.31 μmol/L vs. 75.32 μmol/L), median of CK (117.50 U/L vs. 88.70 U/L), median of CKMB (2.09 ng/ml vs. 1.86 ng/ml), median of LDH (167.75 U/L vs. 147.75 U/L), median of Myo (37.00 ng/ml vs. 31.60 ng/ml), median of ALT (23.45 U/L vs. 20.00 U/L) and median of AST (24.25 U/L vs. 19.20 U/L). Compared with indexes before the intervention, the biochemical indexes of each organ were effectively improved, and the difference was statistically significant (P<0.05). Conclusions The incidence of striated muscle injury and vital organ injury is higher in recruits under the condition of high-intensity training, and hydration and alkalization of urine can reduce the incidence of striated muscle injury and vital organ injury.
