The study analysed the physical development rates of 9-11 year-old male residents (n=110) of the Russian Yugra North versus their track records in the cross country skiing sport. The subjects were split up into the following six groups: (1) 9 year old beginner (first-year) racing skiers; (2) 10 years old second-year racing skiers; (3) 11 years old third-year racing skiers; and (4, 5, 6) three Reference Groups of the 9, 10 and 11 years old non-sporting peers. The study found that the non-sporting schoolchildren showed the first signs of the “growth leap” by the age of 10 versus their cross country skiing peers who were one year later in this aspect (11 years of age). This finding may be explained by the physical load effects. The physical development indices showed domination of the weak body types in every study group, with some dominance of the mesomorphic body type with some distortion of the growth processes in favour of the transversal body dimensions.

Keywords: schoolchildren, physical development, cross-country skiing.
