Resumen


RESUMEN

El objetivo del estudio fue analizar la respuesta inflamatoria y antiinflamatoria a un esfuerzo agudo e intenso de natación, durante la fase preparatoria para los campeonatos nacionales absolutos brasileños. Participaron 20 nadadores. Se determinaron las concentraciones plasmáticas de IL-6, TNF-α, sTNFR1, IP-10 y MCP-1, antes y 40 minutos después de 2 series de 4 repeticiones de 50 metros nadados a la máxima intensidad con 3 minutos de recuperación entre cada repetición y una recuperación activa nadando 1500m a intensidad suave después de cada una de las dos series.  En respuesta al ejercicio agudo únicamente la concentración sTNFR1 se redujo, no presentando cambios en IP 10, IL-6 ni TNF-α. Por tanto el ejercicio agudo en natación en personas bien entrenadas no parece producir una respuesta inflamatoria.

PALABRAS CLAVE: natación, citoquinas, quimiocinas.

 

ABSTRACT

The mean of the study was to analyze the inflammatory and anti-inflammatory response to an intense and intense swimming effort during the preparatory phase for the Brazilian National Adult Championship. Twenty swimmers participated. Plasma concentrations of IL-6, TNF-α, sTNFR1, IP-10 and MCP-1 were determined before and 40 minutes after 2 sets of 4 repetitions of 50 meters swam at maximum intensity with 3 minutes of recovery between each repetition and an active recovery swimming 1500m at low intensity after each of the two series. In response to acute exercise only the sTNFR1 concentration was reduced, with no changes in IP-10, IL-6 or TNF-α. Thus, acute exercise in swimming in well-trained people does not seem to produce an inflammatory response.

KEY WORDS: swimming, citokynes, chemokines.
