ABSTRACT

SUMMARY:

Supplementation is a strategy to potentiate physical training through hypertrophy of skeletal muscles, but other tissues such as the prostate may also be affected. Changes in prostate size and function are associated with the behavior of individuals, but evidence for an association with supplementation is scarce. Therefore, the aim of our study was to evaluate the effect of b-hydroxy bmethylbutyrate (HMB) supplementation and concurrent training on the prostate. Wistar rats were divided randomly into four groups with 10 animals each control group (C), supplemented group (S), training group (T), and supplemented plus training group (TS). The supplemented groups (S and TS) received 76 mg·kg/day of HMB and the concurrent training groups (T and TS) performed exercise three times per week for eight weeks. HMB increased body composition, total weight of the prostate, and altered the histology of prostatic compartments. The lateral prostate of animals in the supplemented group had an increase in mast cells per mm2 (28.0 ± 3.9) compared to the control and exercise group (6.1 ± 3.0; 2.3 ± 0.9) There was also an increase in inflammation in the stroma and lumen of the prostate, and increased expression of androgen receptor (AR) in the supplemented and trained supplemented group (79.8 ± 2.1; 76.8 ± 11.4) in relation to the trained group (61.5 ± 7.0). We concluded that HMB alters hormone receptors that induce morphological changes and inflammation, and animals in the concurrent training group had normal inflammatory and hormonal profiles, and favorable prostatic histology.
RESUMEN
RESUMEN La suplementación con β-hidroxi β-metilbutirato (HMB) es una estrategia para potenciar el entrenamiento físico a través de la hipertrofia de los músculos esqueléticos, pero otros tejidos como la próstata también pueden verse afectados. Los cambios en el tamaño y la función de la próstata están asociados con el comportamiento de las personas, pero la evidencia de una asociación con la suplementación es escasa. Por lo tanto, el objetivo de nuestro estudio fue evaluar el efecto de la suplementación con β-hidroxi βmetilbutirato (HMB) y el entrenamiento concurrente en la próstata. Las ratas Wistar se dividieron aleatoriamente en cuatro grupos con 10 animales cada uno grupo de control (C), grupo suplementado (S), grupo de entrenamiento (T) y grupo de entrenamiento suplementado (TS). Los grupos suplementados (S y TS) recibieron 76 mg•kg / día de HMB y los grupos de entrenamiento concurrentes (T y TS) realizaron ejercicio tres veces por semana durante ocho semanas. HMB aumentó la composición corporal, el peso total de la próstata y alteró la histología de los compartimentos prostáticos. La próstata lateral de los animales en el grupo suplementado tuvo un aumento en los mastocitos por mm2 (28,0 ± 3,9) en comparación con el grupo de control y ejercicio (6,1 ± 3,0; 2,3 ± 0,9) También hubo un aumento de la inflamación en el estroma y la luz de la próstata, y aumento de la expresión del receptor de andrógenos (AR) en el grupo suplementado y entrenado (79,8 ± 2,1; 76,8 ± 11,4) en relación con el grupo entrenado (61,5 ± 7,0). Concluimos que el HMB altera los receptores de hormonas que inducen cambios morfológicos e inflamación, y los animales en el grupo de entrenamiento concurrente tenían perfiles inflamatorios y hormonales normales y una histología prostática favorable.
