简要总结
The study objective consists of the following two aims:
- Compare the effect of daily intake of Jarlsberg and Norvegia cheese on bonehealth in active Cross Country- and Biathlon skiers of both sexes.
- Compare the effect daily intake of Jarlsberg and Norvegia cheese in change of the metabolism , Muscle Strength, Muscle Mass and endurace in active Cross Country- and Biathlon skiers of both sexes.
Population and sampling; The study population consists of active skiers of both genders past 17 years of age for females and 18 years for males. The study sample concists of 30 female and 30 male skiers equally randomized to either Jarlsberg or Norvegia cheese for 24 weeks.
Study performance: Blood samples were collected at baseline and every eight week. Metabolism , Muscle Strength, Muscle Mass and endurance were recorded at start and at the end of the study. Diet and exercise volume were recorded and monitored every eight weeks together with daily cheese intake.

1 Objectives
The study objective consists of the following two aims:
i. Compare the effect of daily intake of Jarlsberg and Norvegia cheese in change of the OC level and Carboxylated Osteocalcin(cOC), Bone Mineral Density (BMD), Trabecular bone score (TBS) and other bone markers in active Cross Country Skiers and Biathlon skiers both sexes.
ii. Compare the effect daily intake of Jarlsberg and Norvegia cheese in change of the Resting metabolic rate (RMR), Muscle Strength (MS), LM and Peak VO2 in active Cross-country Skiers and Biathlon Skiers of both sexes.
2: Population and sampling The study population consists of active Cross-country and Biathlon Skiers both sexes past 17 years of age for females and 18 years for males.
