A four second eccentric squat test (EST) specific to the sport of alpine skiing was developed and standardized. Eighteen men aged 21-30 with one year resistance training experience participated in this study. The reliability of the EST and various jump tests was calculated and the relationship between EST and SSC performance was examined through the correlation of jump test variables and EST performance. The EST was observed to be highly reliable (ICC 0.99). The kinematic characteristics of the EST were closely related to those of alpine skiing. The reliability of the jump test performance variables ranged from low to high (ICC 0. 10-0.90). Investigators should be aware that the reliability of force and power measures can be confounded by changes in jump strategy between jump test trials. The relationship between slow eccentric strength and SSC performance was dependent on whether the jump was performed for maximal height or minimum contact time. / School of Physical Education
