Methodology: Relevant literature was reviewed from many peer review publications. Cross-country skiing differs widely from alpine skiing and snowboarding as it is an endurance event usually run on a circular track in the snowbound areas. Cross-country skiing requires full effort from an athlete, be it physical, physiological or anthropometric. The Snow skiing is a game which requires almost all physical, physiological, anthropometric and biomechanical parameters for improving performance of athletes. These parameters are Aerobic Capacity, muscular strength, flexibility, oxygen uptake, cardiac output, muscle size, weight, body mass index, lean body mass, air drag, snow ski friction, ground reaction forces, radius of the turn and trajectory of the skies and center of mass. But in this study we are concerned with only physical, physiological and anthropometric parameters essential for the success of cross-country skiers. Based on the various studies we have chosen those variables which play a dominant role in improving performance or are at least helpful in showing ones peak performance.

Conclusion: While concluding we can say that variables like general strength and kinetics, upper body power, lactate threshold, oxygen uptake, body composition are essential for cross-country skiers.
