Effects of a five-day Nordic skiing camp on the individuals and on the group.

Abstract
 Scholars from diverse disciplines are increasingly concerned with the benefits generated by the practice of physical activity in the natural environment on individuals (Gomila Serra, 2014; Jirásek et al., 2016). This chapter attempts to shed light on the various scientific approaches that confirm this beneficial relationship. It also contributes to the holistic and integral conception of the human being, made up of different dimensions: physical, mental, emotional and social (Sandell et al., 2009; Borkowski, 2011). After an introductory approach to the relationship between outdoor sports and the integral development of their participants, an empirical study is shown. A five-day Nordic skiing camp is used to evaluate the effects of this practice on the individuals and on the group.
