ABSTRACT The present study has been conducted in order to establish the possible differences that could result from evaluating jump capacity, as a means for power estimation, in two different locations such as laboratory and field. We have evaluated twelve basketball players of the University of Córdoba (UCO), Spain, who compete in the national University League. The mean age for the players was 22 ±2.17 ys. The applied tests, to which the sportsmen were accustomed, were the squat jump (SJ), counter movement jump (CMJ), and counter movement jump with arm swing (CMJas). The centre of gravity height from the jumps was measured with an infra-red rays platform linked to the Muscle Lab system. We left a three day period between the in-lab evaluation and the field one in order to avoid a possible contamination effect of the training on the second evaluation. For both evaluations we maintained constant several characteristics and parameters such as the trainer’s presence, same number of people, same clothing and shoes so as to minimize the effects of such elements and do the closest approximation possible, for the moment, to the variable we are interested in investigating, that is, the location of evaluation. We find statistically significant differences when we do field evaluation versus the laboratory evaluation for the three types of jump analysed: SJ (37.88 ± 0.96 vs 35.88 ± 1.19) p
