MARTINEZ-ABELLAN, A. et al. Design and content validation of a questionnaire on Weight Loss in Combat Sports (PPDC). CPD [online]. 2016, vol.16, n.3, pp.113-122. ISSN 1989-5879.

The weight classes system established for most of the combat sports promotes the implementation of methods and strategies to reduce the athletes´ body mass before the official weigh-in, and other habits and protocols of fast rehydration and fill the energy reserves in the period of time (6-20 h) that separate the official weigh-in and the beginning of the tournament. The aim of this study was to design and validate for the first time a questionnaire to assess the habits that are conducting by the combat sport athletes during the phases of weight loss and the subsequent recovery. After the original design of the questionnaire, we verified the construct validity and structural validity of the instrument through agreement and consensus of 12 expert judges. Second, we conducted a study of the compression validity and reliability of the items that compose the instrument using a sample of 46 experienced combat athletes. The results indicated that the weight loss in combat sports questionnaire provides optimal levels of content validity, as well as reliability in their answerers that allows researchers and coaches to identify and monitor the methods, frequencies and strategies that these kind of athletes carry out during the rapid weight loss phases before the official weigh-in and the subsequent recovery phases before the start of the tournament.
