Comparative study of lactaemia between girls and boys aged 11 to 12 years of the club rnboumerdes case athletics (400 M flat)‎ and swimming (100 M 4 swims)‎

Throw this study we aimed to reconsider the idea that there is no physiological difference between pre-pubescent boys and girls during lactic anaerobic exercise; recent studies Ratel.

S, Martin.

V (2012) show that the activity of the lactic anaerobic metabolism of the child is not different from that of the adult.

the study of anaerobic function during growth has not received the same attention from researchers as aerobic function.

this is quite surprising in view spontaneous activity of children.

we note that a lot of research has been done on anaerobic metabolism in children but very little on the comparison between girls and boys in the production of lactate.

in our study we have compared blood lactate result obtained during our experimentation, between the two sexes in runners as well as in swimmers, and between the total sample of females and males after exercise.
