Abstract
This study evaluated the effect of selective loads periodization on physical performance and biochemical parameters in professional female futsal players during competitive season. Twelve elite female futsal players from Kindermann team (Brazil) participated in the study. Variables of physical performance and erythrogram, leukogram, plasma cortisol, plasma immunoglobulin A (IgA) in the beginning of the preparatory period (PP), in the competitive period (CP) and in the final competitive period (FCP) were evaluated. Using selective loads periodization, all variables of physical performance increased (p < .01) during CP and were maintained during FCP (p < .05). White blood cells did not modify during CP and the increase of FCP in 28% remained within normal ranges. Plasma cortisol also increased during CP (p < .01) and was within the normal ranges during FCP. Plasma IgA also was within the normal ranges during CP and FCP. Selective loads periodization is adequate and attends the requirements of the sport during competitive season in female futsal players.
Highlights
In Brazil, futsal is the sport with the highest number of practitioners with almost 12 million followers (Salles & Moura, 2013)
Body fat reduced by 15% in the final competitive period when compared with beginning of preparatory period (p < .001) and by 10% in the competitive period when compared with the preparatory period (p < .05) (Table 2)
The lean body mass increased by 2% and 3% in the competitive period and final competitive period when compared with the beginning of preparatory period (p < .05) (Table 2)
Summary
In Brazil, futsal is the sport with the highest number of practitioners with almost 12 million followers (Salles & Moura, 2013). Female players are engaged in several competitions. They often play two or more games a week, with short rest periods and inadequate recovery to restore energy reserves, increasing muscle and psychological fatigue. Athletes show high disease and infection incidence, increased injury risk during pre-season training periods which yields decreased the physical performance of teams during games (Avloniti et al, 2007). The Block Periodization model proposed by Verchoshansky (1985) has been used for team sports such as soccer (Wahl, Güldner, & Mester, 2014), basketball (Moreira, Oliveira, Okano, Souza, & Arruda, 2004) and male futsal (Toledo & Corradine, 2008), no study with female futsal players was carried out until this time with others periodization models during competitive season
