Acute and Chronic Testosterone Response to Blood Flow Restricted Exercise

Abstract: The American College of Sports Medicine recommends lifting a weight of at least 70% 1RM to achieve muscular hypertrophy as it is believed that anything below this intensity rarely produces substantial muscle growth. At least part of this recommendation is related to elevated systemic hormones following heavy resistance training being associated with skeletal muscle hypertrophy. Despite benefits of high intensity resistance training, many individuals are unable to withstand the high mechanical stresses placed u… Show more

“…This increased IGF--1 response to BFR resistance exercise was also observed by Takano et al (88); moreover, BFR in conjunction with walking did not increase IGF--1 (3). A recent review by Loenneke et al (56) indicated minimal acute and chronic testosterone changes subsequent to BFR plus exercise. Studies that examined the total testosterone (3,26,76) and free testosterone responses (3,76) to BFR have indicated no significant increases.…”

“…The influence of acute and chronic BFR exercise on other anabolic hormones such as testosterone (T) is also unclear [38]. For example, neither Reeves et al [39] nor Fujita et al [20] observed changes in total or free following arm or leg BFR resistance exercise, respectively.…”

“…Por tanto, independientemente del gradiente hormonal, la hipertrofia muscular es el resultado de un desequilibrio entre la tasa de degradación de las proteínas y su tasa de síntesis. El mecanismo de acumulación metabólica y la elevada respuesta de la GH al ejercicio en oclusión podrían, por tanto, tener un papel únicamente regulador a nivel metabólico y no en el balance de síntesis proteica (111). En este sentido, algunos autores han demostrado que pueden producirse adaptaciones estructurales sin elevaciones de los niveles de GH (45) ni de testosterona (111).…”

En este sentido, algunos autores han demostrado que pueden producirse adaptaciones estructurales sin elevaciones de los niveles de GH (45) ni de testosterona (111). De hecho, el entrenamiento oclusivo ha demostrado incrementar el tamaño muscular a pesar de estimular pobremente la secreción de IGF-1 y no mostrar apenas respuesta a la testosterona (54,111).…”
