“…The weight loss was already studied and considered negative in some studies due to its potential malign effects over health and performance 2 . There are still innumerous physiologic and psychologic alterations caused by such process, considering that, in elite sports, a minimum loss at performance can be crucial at a combat decision 5 .…”

“…The strategies of weight loss affect the cardiovascular system, provoking decrease of plasmatic volume blood, increase of the heart rate in rest, lower level of blood ejection, resulting in lower capacity to sustain work at a constant rate 4,5 . In this way, the analysis of heart rate variability enables to gauge the autonomic nervous system modulation, under different physiological conditions, and can demonstrate oscillations of intervals between consecutive cardiac pulses, that are related to the influences of autonomic nervous system over the sinus node, being a non-invasive method capable of identifying cardiovascular phenomenon in healthy individuals, athletes and disabled people 6 .…”

“…É comum também a desidratação do corpo em saunas ou banheiras quentes, sem ingerir nenhum líquido no período. A desidratação tem sido descrita pela literatura com um dos momentos mais agressivos para o corpo do atleta e que pode colocar sua vida em risco (American College of Sports Medicine, 1999;Franchini, Brito & Artioli, 2012;Pahl, Vaziri, Akbarpour, Afrasiabi & Friis, 1988).…”

“…Quase que diariamente são pressionados a otimizarem o desempenho esportivo (KRENTZ;WARSCHBURGER, 2013;LOURENÇO-LIMA;HIRABARA, 2013;PERINI et al, 2009;VIEIRA et al, 2006), principalmente por parte dos treinadores. Vários atletas associam a redução ou manutenção do peso corporal com a maximização da performance (FORTES et al, 2013;ROSENDAHL et al, 2009;TORSTVEIT, 2010).…”

“…Evidências indicam que cerca de 50% das atletas utilizam a restrição alimentar para manter ou reduzir o peso corporal (FORTES et al, 2013;KRENTZ;WARSCHBURGER, 2013;MARQUET et al, 2013;PIETROWSKY;STRAUB, 2008;VIEIRA et al, 2006). Contudo, vale ressaltar que a restrição alimentar, pelo fato de inibir a reposição energética adequada, pode gerar decréscimos no desempenho de atletas (GARTHE et al, 2011;LOURENÇO-LIMA;HIRABARA, 2013). Assim, considerando que a reposição de glicogênio muscular (substrato energético mais importante durante a maior parte das provas de atletismo, natação e ginástica artística) depende de bom aporte energético advindo de refeições (GARTHE et al, 2011), as atletas que fazem jejum podem ter atenuação do desempenho anaeróbio durante as competições (PERINI et al, 2009), o que culmina em baixo rendimento competitivo.…”
