Hydration Habits of Elite Field Futsal Players during Official Matches: Defenders and Forwards

Abstract

Futsal is a variant of soccer that is played on a smaller playing surface and mainly indoors. Futsal is played between two teams of five players, and unlimited substitutions per team are permitted. The purpose of this study has been to determine and to compare hydration habits and level of dehydration in elite futsal players during competition in relation to playing position. 4 defenders (DF) and 5 forwards (FW) were studied during 3 official matches (22-26 ºC and relative humidity 32-42.33%) in the Spanish Futsal League (LNFS). Sweat loss was assessed through changes in body mass after correction for fluid intake (ad libitum) and urine loss. To analyze this data the statistics used are descriptive and not parametric. Mean sweat lost was higher in FW (2458±670.91 mL) than in DF (1695.56 ± 673.732 mL). Fluid intake was higher in FW (1700.36 ± 857.12 mL) than in DF (1493.33 ± 770.35 mL). FW replaced less total fluid lost (63.64 ± 29.55%) than DF (79.53 ± 38.71%), so FW incurred a mean body mass deficit of 1.23 ± 1.10%, higher than DF (0.59 ± 1.10%). Even FW and DF were aware of the impact that dehydration has on performance. There is a significant correlation between game time and body weight loss (Spearman's Rho = 0.419, p ≤ 0.05). There is significant difference in sweat lost in relation to playing position (p = 0.020; ES = -1.311). We conclude that in these players, during official games, and independently of position, hydration status can be seen to maintain itself through regular substitutions and also the correct level of fluid intake. However, data allow for an individualisation of player hydration strategies, not taking exclusively into account playing position or game time.

Efficacy of an Educational Intervention for Improving the Hydration Status of Female Collegiate Indoor-Sport Athletes

“…In agreement with previous research 11,20 , athletes in the current study were able to replace enough fluids to prevent significant dehydration, although mild dehydration was still seen occasionally. The lack of improvement in BM changes after the intervention was likely due to the fact that many participants had adequate hydration prior to the intervention.…”

“…[15][16][17][18] The few studies that have assessed indoor athletes have also shown that sweat rates are high and dehydration is still prevalent. 11,20,21 This has been found to be especially true in basketball players because of its intermittent nature. 21,22 Research on volleyball players is limited; the only study examining volleyball players' hydration status utilized adolescents athletes in a non-airconditioned facility.…”

The efficiency of actions of goalkeepers from sports effective teams in a game of futsal in matches of the final tournament of the World and European Championships in 2012

“…Hence intensive research on knowing the game has been conducted for several years. Somatic determinants [29,30,31,32,33], physiological-motor [34,35,36,37,38,39,40,41], psychological [42,43,44,45,46] as well as technical and tactical performance [47,48,49,50,51] have already been studied. The efficiency futsal players' game has been studied, among others by Silva et al [29], Panfil and Paluszek [52], Szwarc [2], Irokawa et al [53], Leite [54], as well as Aires [55], Da Silva et al [56], Buraczewski [57], Travasson [58], Vilar [59], Gomez [60], Noel [61], Lapresa et al [62] and Sarmento et al [63].…”
