The study was aimed to clarify the relationship between the laboratory fitness test for junior alpine ski racers and the field test which is recently reported by Takeda et al.（ 2021）, and to suggest ideal fitness test to estimate skiing performance for junior alpine ski racers. Twelve male and eight female junior high school athletes participated in this study. For the laboratory test, the vertical jump, the isokinetic knee extension strength, the maximal anaerobic power test, the bending jump test, the hexagonal jump test, the hexagonal obstacle jump test, the Wingate 40s test, the high box 90s test（ HB90）, maximal oxygen consumption （MOC）, and the standing trunk flexion in laboratory （ Stand-T-Fl-Lab） were measured. As for skiing performance, both of slalom（ SL） and giant slalom（ GS） seasonal points provided by the International Ski Federation（ FIS） and the Ski Association of Japan（ SAJ） were measured. To clarify the correlation between the laboratory test and field test, the field test data were reported by Takeda et al.（ 2021） were used. To clarify a relationship between the laboratory test and the field test, and skiing performance with the laboratory test, Pearson's correlation coefficient was tested. As a result, the HB90, MOC and Stand-T-Fl-Lab test were correlated with High box jump test 60s （HB60）, 20-m Shuttle run and Standing trunk flexion in both sexes, respectively. The other correlations between the laboratory test and the field test reported by Takeda et al.（ 2021） were observed, however, different between the sexes. The Figure eight running and HB60 reported by Takeda et al. （ 2021） were correlated to SL for males and the One leg lateral hopping test reported by Takeda et al.（ 2021） and MOC were correlated to both SL and GS for females.
