ABSTRACT
Objective To explore an appropriate training method to quickly improve the soldiers' aerobic endurance capacity and decrease the incidence of military training injuries for combat troops. Methods Two hundred and forty-eight recruits (males,Hanzu) from infantry without previous history of military training were involved in the present study,and they were divided averagely into experimental group and control group (124 each). Intensified endurance training designed with the theory of "cyclic training" was applied in experimental group,and routine training method was applied in control group including mainly 5000 meters running (no more than once a day,3 times a week). The resting pulse,vital capacity,maximal oxygen consumption (VO2max) and the performance of 5000m running were determined before and after eight-week-training as endurance capacity indices. Physical examination was performed to count the cases of military training injuries including calf swelling and tenderness,knee swelling and pain,and low back pain,and then the incidence of military training injuries was calculated. Results In the experimental group,the resting pulse decreased by 8.0%,while the vital capacity,VO2max and 5000m running performance elevated by 8.1%,20.0% and 14.7% respectively after training,which were significantly different in comparison with that before training and of control group (P
ABSTRACT
Objective To evaluate the influence of angiotensin converting enzyme (ACE) gene polymorphism on the effect of aerobic endurance training of soldiers.Methods Two hundred and forty-eight army recruits (males,Hans) from an infantry regiment without previous history of military training were involved in the present study,and they were divided into experimental group and control group (124 each).Intensified endurance training designed with the theory of "cyclic training" was applied in experimental group,and routine training method was applied in control group including mainly 5000 meters running for 3 times in one week (no more than 1 time per day).The 5000m running performance and maximal oxygen consumption (VO_2max) were determined before and after eight-week training as endurance capacity indices.The ACE gene polymorphism was determined and the recruits in both groups were divided into 3 sub-groups according to the ACE genotypes as II,ID and DD.The influence of ACE genotype and training method on endurance capacity was analyzed.Results The 5000m running performance and VO_2max of experimental group after eight-weeks-training were significantly higher than those before training and those of control group (P0.05).In control group,the 5000m running performance and VO_2max of DD sub-group were significantly lower than those of II sub-group and ID sub-group (P0.05).Conclusions Intensified endurance training designed with the theory of "cyclic training" may effectively improve the endurance capacity in 8 weeks.ACE genotype could not be used as an accurate indicator to evaluate the endurance capacity and improvement of efficiency of soldiers.
