“…As butterfly events normally are held from 50m to 200m, the comparison between butterfly and freestyle swimming is limited. The study is limited since variables such as physiological parameters [18], anthropometric characteristics [27], training data [41], nutrition [42,43], and motivational [44] factors were not considered. These variables may have had an influence on race outcome.…”

Beat (2014). The fastest female butterflyswimmers were younger than the fastest male butterfly swimmers. Medicina Sportiva, 18(1):1-9. DOI: https://doi.org/10.5604/17342260.1094778 THE FASTEST FEMALE BUTTERFLY SWIMMERS WERE YOUNGER THAN THE FASTEST MALE BUTTERFLY SWIMMERS AbstractIntroduction: The age of peak freestyle swimming speed was reported to be at ~17 years for women and ~19 years for men. However, the age of peak swimming speed for other strokes such as butterfly is not known.Objectives: We investigated whether the age of peak swimming speed and peak swimming speed changed across years in elite butterfly and freestyle swimmers at national level (Switzerland) between 1994 and 2011.Methods: Changes in swimming speed and age of the annual ten fastest swimmers across years were investigated using linear regression analyses and two-way analysis of variance (ANOVA).Results: For both butterfly and freestyle, the age of peak swimming speed was ~19 years for women. For men, the age of peak swimming speed was at ~22 years over all distances with the exception in 200m freestyle with ~21 years. The age of peak swimming speed increased for women in 50m from ~19 years to ~21 years, in 100m and 200m butterfly from ~18 years to ~20 years while it remained unchanged in 50m, 100m and 200m freestyle at ~19, ~18 and ~20 years, respectively. For men, the age of peak swimming speed was constant for butterfly at ~24, ~23 and ~21 years, respectively, and for freestyle at ~23 years in 100m and ~22 years in 200m across years with the exception of a decrease in 50m freestyle from ~23 years (1994) to ~22 years (2011). Both women and men increased peak swimming speed over all distances. Sex difference in peak swimming speed increased in butterfly from 10% in 1994 to 12% in 2011 in 50m to 200m and in freestyle in 100m from 12% in 1994 to 14% in 2011 while it remained unchanged in 50m and 200m freestyle at 12% and 10%, respectively.Conclusion: To summarize, in butterfly swimming, women seemed to achieve peak swimming speed at ~19 years and men at ~21-22 years. For practical applications, a career as butterfly swimmer may endure longer in men compared to women.

“…Mais especificamente, após o exercício, deve-se ingerir cerca de 150% da perda de massa corporal 4 . O ideal seria definir estratégias de hidratação avaliando a MC inicial e final, para evitar o estado de desidratação cumulativo e progressivo 7,27 . No entanto, a qualidade do líquido ingerido também deve ser observada, pois apesar do poder de hidratação da água pura demonstrado nesse estudo, é possível que esta forma de hidratação não tenha oferecido uma reposição de eletrólitos adequada, visto que muitos são perdidos pela sudorese durante o exercício 28,29 .…”

RESUMOO objetivo desse estudo foi avaliar o impacto da reposição hídrica com água de coco sobre o estado de hidratação e cardiovascular drift durante o exercício. Treze voluntários do sexo masculino realizaram três sessões de exercício em cicloergômetro, submetidos a formas distintas de hidratação: grupo sem água (SA); grupo com água (CA); e grupo água de coco (CAC). O estado de hidratação foi determinado por alterações percentuais na massa corporal (∆ %MC) e urina. A frequência cardíaca (FC) foi registrada para avaliar o cardiovascular drift. Houve um aumento significativo da desidratação no grupo SA (∆ %MC = -1,43 ± 0,15), comparado aos grupos CA (∆ %MC = -0,68 ± 0,15) e CAC (∆ % MC = -0,70 ± 0,19). O grupo SA demonstrou aumentos significativos da FC comparado aos outros grupos. Conclui-se que a água de coco favoreceu a hidratação e a redução da FC, evitando o cardiovascular drift, mas com impacto similar à água. Palavras-chave: Desidratação. Exercício. Frequência Cardíaca. ABSTRACTThe purpose of this study was to evaluate the impact of fluid replacement with coconut water on the hydration status and cardiovascular drift during exercise. Thirteen male volunteers performed three sessions of exercise in bicycle ergometer, submitted to different forms of fluid replacement: no water intake (NW) group; with water intake (WW) group; and with coconut water (WCW) group. Hydration status was determined by percentage body mass changes (∆ % BM) and urine. Heart rate (HR) was recorded to evaluate the cardiovascular drift. There was a significant increase of dehydration in the NW group(∆ % BM = -1.43 ± 0.15) compared with WW(∆ % BM = -0.68 ± 0.15) and WCW groups(∆ % BM = -0.70 ± 0.19). The NW group showed significant increases in HR compared to other groups. It was concluded that coconut water promotes hydration and HR reduction, preventing cardiovascular drift, but similar to water impact. Keywords: Dehydration. Exercise. Heart Rate. IntroduçãoO cardiovascular drift é caracterizado pelo aumento exacerbado da frequência cardíaca (FC), acompanhado pela redução do volume de ejeção (VE) e fluxo sanguíneo para o músculo exercitado em estado de desidratação 1 . Sabe-se que tal condição pode promover alterações na prescrição do exercício e desempenho 2 . Obviamente, a intensidade, a duração do exercício, a aclimatação ao calor e o estado de hidratação vão ditar a extensão do cardiovascular drift 3 . Assim, manter uma hidratação adequada é importante para que não seja desencadeado o cardiovascular drift durante as sessões de exercícios, especialmente em atletas sob situações de estresse térmico 4 . Porém, independentemente do estresse térmico e do atleta, sabe-se que a manutenção do estado de hidratação adequado é fundamental para a saúde e desempenho de todos os praticantes de exercício 5 . O ideal seria definir estratégias de hidratação, para evitar o estado de desidratação cumulativo e progressivo 6,7 . A utilização de marcadores simples como alteração
