    (Universidad de Murcia, Servicio de Publicaciones, 2023) Fuentes-Nuñez, Javier; Olivares-Gómez, Carelia; Farías-Valenzuela, Claudio; Poblete-Aro, Carlos; Alvarez-Arangua, Sebastián; Ferrero-Hernández, Paloma
    Esta revisión tiene como objetivo declarar los beneficios del ejercicio físico y/o la actividad física en los cinco tipos de cáncer con mayor tasa mortalidad en el mundo. Se realizó una búsqueda en las bases de datos: Pubmed, Cochrane, Scopus, Web of Science, Scielo (Latinoamérica) y Medline. Los términos usados para la búsqueda fueron: “cáncer de pulmón”, “cáncer de hígado”, “cáncer de mama”, “cáncer de estómago”, “cáncer de colon”, “ejercicio físico”, “actividad física”, “ejercicio de resistencia” y “ejercicio aeróbico”. El ejercicio físico y la actividad física han demostrado beneficios tanto en variables morfológicas, metabólicas y psicológicas, teniendo un impacto positivo en el aumento de la funcionalidad, esperanza de vida y calidad de vida en pacientes con cáncer. El ejercicio aeróbico demostró mayores beneficios en el consumo de oxígeno, además de una alta adherencia, mientras que el entrenamiento de fuerza en una mayor capacidad específicamente en los miembros inferiores.

    Global warming and its effects on human health encouragethe examination of the effect of resistance exercise and heat stress on cytokines production. The aim of this study was to investigate the interaction effect of resistance training and heat on the immune system of healthy active men. Six trained males (27.83±1.9 years, 86.45±10.3 kg) completed a 60-minute resistance exercise with 75% 1RM in two conditions (~25 °C, normal or ~35 °C, heat). The following were evaluated: LPS-stimulated cytokine production, plasma cytokine levels, and cortisol. The results showed that heat stress increased (P=0.027) plasma IL-6 and remained high after 1 hr (P=0.026). Upon stimulation with LPS, IL-6 cell production in heat and normal conditions increased immediately (PH=0.026; PN=0.048), decreased 1 hr after exercise, and returned to baseline (PH=0.005; PN=0.033). However, post-exercise LPS-TNF-α release decreased immediately only in a heated environment (P=0.029). The concentration of blood cortisol was unaffected by normal or heat conditions. The findings of this research suggest that other factors beyond cortisol regulated cytokines during heat-exposed exercise. Furthermore, the IL-6 had a regulatory function on TNF-α release. These cytokine changes showed that real work in similar temperatures did not negatively affect the immune system.

    The importance of physical activity in osteoporosis. From the molecular pathways to the clinical evidence
    (Universidad de Murcia. Departamento de Biología Celular e Histología, 2016) Castrogiovanni, Paola; Trovato, Francesca Maria; Szychlinska, Marta Anna; Nsir, Houda; Imbesi, Rosa; Musumeci, Giuseppe
    Osteoporosis is a very common bone disorder characterized by low bone mass and signs of deterioration, responsible for bone fragility typical in this pathology. The risk factors for the onset of osteoporosis are many and different from each other. Some of them cannot be modified, such as age, hereditary diseases and endocrine diseases. Others are modifiable, so that prevention is an advisable tool to reduce the incidence of osteoporosis. Among preventive tools, physical activity is certainly a valid instrument of prevention, in fact physical activity contributes to a healthy energy balance and increases muscle mass and bone mass. In the present narrative review, we wanted to pay attention to the possible influence of physical activity on the pathophysiological molecular pathways of osteoporosis and to the use of different exercise training in treatment of osteoporosis. From the literature analyzed, in relation to the effects of physical activity on bone metabolism, it is shown that exercise acts on molecular pathways of bone remodeling involving all cellular types of bone tissue. In relation to clinical trials adopted in patients with osteoporosis, it is evident that a multi-component training, including aerobic activity and other types of training (resistance and/or strength exercises), is the best kind of exercise in improving bone mass and bone metabolism in older adults and especially osteopoenic and osteoporotic women. With regard to whole-body-vibration training, it seems to be a valid alternative to current methods due to its greater adaptability to patients. In conclusion, physical activity, whatever the adopted training, always has beneficial effects on patients suffering from osteoporosis, and not only on bone homeostasis but on the whole skeletal muscle system.
