A systematic review with meta-analysis was conducted to evaluate the effects of circuit resistance training (CRT) on cardiorespiratory fitness, strength, and body composition in middle-aged and older women. Sixteen studies were included in the meta-analysis. The CRT interventions led to a significant decrease in weight, body mass index, and fat mass along with an increase in muscle mass. Significant differences were found in the fat mass and a trend to develop muscle mass when compared with the control group. CRT led to a significant increase in VO2max, walking endurance, and time to exhaustion; likewise, significant differences were observed when compared with the control group. CRT had a moderate and large favorable effect on arm, trunk, and lower limb strength. Furthermore, the increases in strength observed in the CRT were significantly greater than the changes observed in the control group. In middle-aged and older women, CRT improved cardiorespiratory fitness and strength and optimized body composition.


Background and Aims: Researchers have recently considered the impact of herbal supplements combined with exercise on weight control. This study aimed to investigate the effect of Spirulina platensis green-blue algae consumption, and circuit resistance training (CRT) on lipid profile in overweight and obese middle-aged men. Materials and Methods: This was a single-blind, quasi-experimental, and applied study. The study population included 60 overweight and obese men in the age range of 30-55 years with a body mass index of more than 25 (kg/m2). The participants were purposefully selected and randomly divided into four groups of training plus spirulina (N=15); training plus placebo; spirulina; and Placebo. The intervention and placebo groups took two 500 mg spirulina capsules, and placebo capsules daily for eight weeks, respectively. The CRT was performed for eight weeks and three sessions per week based on a flexible timing pattern, with the observation of the principle of overload with rest intervals between stations and sets. Results: There was a significant difference between the study groups in terms of the levels of triglyceride (TG), high-density lipoprotein (HDL) of the participants (P<0.05). Moreover, in the intra-group investigation, there was a significant reduction in the values of low-density lipoprotein (LDL), and triglyceride (TG), in the groups of training plus spirulina and training plus placebo, cholesterol (TC), and (Aspartate aminotransferase) AST in the groups of training plus spirulina had a significant decrease, Moreover, a significant increase was observed in the levels of HDL and alanine aminotransferase (ALT) in the group of training plus spirulina. Conclusion: It seems that the consumption of Spirulina platensis green-blue algae combined with CRT can be effective in controlling weight and obesity and preventing obesity-related diseases through the improvement of some indices of metabolic profile and body composition.

Introducción: recientes estudios han confirmado que el entrenamiento de fuerza en circuito podría reducir la masa grasa visceral en mujeres mayores obesas. Para seguir avanzando en esta línea de trabajo, nos propusimos determinar su impacto en marcadores de disfunción endotelial.Material y método: participaron voluntariamente 48 mujeres (70-75 años) con obesidad procedentes de la comunidad. De ellas, 24 fueron asignadas aleatoriamente al grupo experimental para desarrollar un programa de entrenamiento de fuerza en circuito de 6 estaciones durante 12 semanas con 3 sesiones/semana. Los marcadores de disfunción endotelial ensayados fueron: endotelina-1, molécula de adhesión intercelular-1 (ICAM-1) y molécula de citoadhesión vascular-1 (VCAM-1). Asimismo se evaluó su influencia en un test funcional para población mayor como el de sentarse levantarse en 30 segundos. Este protocolo fue aprobado por un comité de ética institucional. Resultados: tras completar el programa de intervención se observó un descenso significativo de los niveles plasmáticos de entotelina-1 (2,28 ± 0,7 vs. 1,98 ± 1,1 pg/ml; p = 0,019; d = 0,67) e ICAM-1 (290 ± 69 vs. 255 ± 76 ng/ml; p = 0,004; d = 0,92). También mejoró significativamente la puntuación del test funcional (18,7 ± 3,1 vs. 23,0 ± 3,6 repeticiones; p = 0,019; d = 0,98). Por el contrario, no se observaron cambios en el grupo control.Conclusión: el entrenamiento de fuerza en circuito mejora la disfunción endotelial presente en mujeres mayores obesas. Futuros estudios siguen siendo necesarios para consolidar su aplicación en clínica.
