RESUMO

BACKGROUND: Decreases in function of the immune system with age contribute to the increase the risk of infectious diseases especially the upper respiratory tract. On the other hand, physical activity has been widely recommended for health. However, more studies are needed to support the benefit effect of exercise on immune system in elderly. AIM: To evaluate the effect of the hydrogymnastics on the serum level of immunoglobulin A (IgA) in elderly women. METHODS: Twenty-six participants were randomly assigned to an experimental (n: 16) or a control group (n: 10). IgA concentrations were determined by nephelometry (BN2 Analyzer, Dade Behring). The hydrogymnastics training protocol was performed 5 times a week during 12 weeks. The intensity of the aerobic exercise was 50-60% of the maximum heart rate monitored by telemetry (Polar-FT7). RESULTS: No significant differences (p: 0.797) resulted by ANOVA on serum IgA levels; the percentage of change in experimental group was Δ% = -6.7 mg/dL compared to the control group, Δ%= -7.4 mg/dL. CONCLUSION: After three months of hydrogymnastics the IgA level did not show significant change on elderly women; However, positive improvement in percentage of change Δ% was found.

Introducción: La disminución de la función del sistema inmune con la edad es asociada a la incidencia de enfermedades infecciosas del tracto respiratorio superior; por otro lado, el ejercicio físico ha sido ampliamente recomendado para la salud. Sin embargo se requiere aún fundamentar con mayor exactitud los efectos del ejercicio físico en el sistema inmunológico en adultos mayores. Objetivo: Evaluar el efecto de un programa de hidrogimnasia sobre la concentración sérica de Inmunoglobulina A (IgA) en adultas mayores. Métodos: 26 participantes fueron asignadas aleatoriamente a un grupo experimental (n: 16) y un grupo control (n: 10). Se determinó la concentración sérica de IgA por nefelometría (BN2 Analyser, DADE Behring). Las sesiones de hidrogimnasia se realizaron cinco veces por semana durante 12 semanas; el ejercicio fue aeróbico a una intensidad de 50-60% de la frecuencia cardíaca máxima controlada por telemetría (Polar-FT7). Resultados: Se utilizó la prueba de ANOVA, indicando no interacción significativa (p: 0,797). El porcentaje de cambio resultó de Δ% = -6,7 mg/dL del grupo experimental en comparación con el grupo control Δ% = -7,4 mg/dL. Conclusiones: Un programa de tres meses de hidrogimnasia en mujeres no mejora significativamente los niveles de IgA. Sin embargo, los datos refieren una mejora positiva el porcentaje de cambio A%.
