Up to a certain age Skiing combines to some extent just fine with other sports. Not just because there are no racing obligations but because all sports have something to offer each other. How does Volley or Judo for example have to do with Ski and vice versa? We would say Volley for the development of agility and Judo for its resilience and Ski respectively for its balance which is useful for all sports. There are complementary sports such as Water Skiing and Skiing that may technically differ but use similar muscle groups, balance, rhythm and coordination training is essential and much more if we want to go deeper. Until a certain age it is legitimate for children to go through different sports even at the same time, not only because it is good for them but also to find their inclination. But at some point they have to choose if they want to be involved in a sport. When is this crucial moment? It is around the age of 11 that things start to get “serious”. It is the moment when they start to enter competitive categories and so, if they do not do the proper training they will be left behind..not that they could not fill the gap and beyond..but this will be more difficult. Yes, at this age they are not physically fit and especially girls have many hormonal changes so in the comparison it will be seen later who wins due to physique and who does not but do not forget that Ski is a technical sport and every route counts. This does not mean that they have to stop doing any other sport but it means they have to focus their strengths and training on one. The demands increase as they ascend to a competitive category so by the age of 13 they must have decided which sport they will follow.
