Obesity and associated chronic inflammation lead to insulin resistance. The aim of this study was to evaluate the effect of varying intensity circuit resistance training on metabolic and inflammatory markers in obese men. In a semi-experimental trial, 44 obese men were selected and randomly divided into four groups, including 1) Control (n=11), 2) Low-intensity circuit resistance training (n=11), 3) Moderate-intensity circuit resistance training (n=11), and 4) High-intensity circuit resistance training (n=11). Resistance training was performed at different intensities, including 1) High-intensity circuit resistance training (80% 1RM), 2) Moderate-intensity circuit resistance (60% 1RM), and 3) Low-intensity circuit resistance training (40% 1RM), three sessions per week for 12 weeks. Serum levels of Dectin-1, TLR2, TLR4, MyD88 were measured using an ELISA kit. Data were analyzed with covariance analysis at P<0.05. Twelve weeks of moderate and high-intensity circuit resistance training significantly reduced weight, body mass index, serum levels of Dectin-1, TLR2, TLR4, MyD88, and HOMA-IR (P=0.001). The reduction of weight, body mass index, serum levels of Dectin-1, TLR2, TLR4, MyD88, and HOMA-IR were significant in obese men in the high-intensity training group compared to low-intensity training (P=0.001). It seems that circuit resistance training, especially high-intensity circuit resistance training, can be used as an option to reduce the inflammatory and metabolic complications associated with obesity.

Background and Aims: Physical activity and blood flow restriction (BFR) training can affect bone metabolism. This study aimed to investigate the effect of a plyometric exercise session with and without blood flow restriction on bone metabolism markers, such as bone alkaline phosphatase (BALP) and C-terminal telopeptide of type 1collagen (CTX), as the markers of bone formation and destruction, respectively, among inactive adolescent females. Materials and Methods: This study was conducted using a quasi-experimental design with pretest-posttest. The participants (n=48) were randomly divided into four groups of high-intensity training (n=12), low-intensity training (n=12), low-intensity training+restricted blood flow (n=12), and control (n=12). The training protocol included 68 jumping movements. The intensity of the exercise was less than two and more than four times the body weight for low intensity groups with and without obstruction and the high-intensity group, respectively. Blood samples were taken before and immediately after the exercise to evaluate BALP and CTX. Data analysis was performed using dependent t-test and one-way ANOVA. A p-value of ≤0.05 was considered statistically significant. Results: A significant decrease was observed in CTX serum levels in high-intensity exercise group (P=0.04) and low-intensity exercise group with limited blood flow (P=0.03), compared to those in the pre-test. However, there was no significant within-group and intergroup changes in serum levels of bone formation marker (P≥0.05). Conclusion: According to the results, a low-intensity plyometric exercise session with blood BFR can be as effective as high-intensity plyometric exercises in altering bone metabolism (reducing bone absorption marker).

Introdution: Non-alcoholic fatty liver disease (NFALD) is a disease associated with metabolic syndrome and lifestyle. The purpose of the present study was to investigate the effect of 12 weeks of circuit resistance training course on interleukin-17 (IL-17) levels, 70 kDa thermal shock protein (HSP70), insulin resistance and serum levels of alanine aminotransferase (ALT), as well as aspartate aminotransferase (AST). Method: In this clinical trial study, 30 males with NFALD were selected through targeted sampling and were randomly assigned to one of two groups of practice and control intervention. The training program included 12 weeks of resistive training and 3 training sessions per week, which was performed as periodic circuit resistance training. Before eating breakfast, blood sampling was done one day before the start of training and 3 days after the last training session. For statistical analysis, paired t-test was used to compare intra-group data. Independent t-test was used for comparison between groups. Data were used via the SPSS v 22 software. The significance was defined as P≤0.05. Results: After the training course, compared to the control group a significant decrease was observed in weight (P = 0.008), BMI (P = 0.006), body fat percentage (P <0.001), insulin resistance (P <0.001), HSP70 (P <0.001), IL-17 (P <0.001), serum levels of ALT (P <0.001) and AST (P <0.001) enzymes. Conclusion: Regarding the results of this study, circuit resistance training has an effective role in improving the liver function in NFALD patients by reducing insulin resistance and levels of inflammatory cytokines, this method of resistance training can be useful in the treatment of these patients.

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.

Abstract Introduction: Sarcoidosis-related fatigue and skeletal muscle dysfunction are frequent symptoms in patients with sarcoidosis. Despite lacking knowledge whether high-intensity resistance training (RT) will worsen fatigue, low to moderate intensity is commonly recommended. This study aimed to investigate whether a single session of high-intensity RT will induce a larger acute increase in fatigue than a single RT session of moderate-intensity. Methods: In this crossover study, 41 patients with pulmonary sarcoidosis (age: 53 ± 11 yr) were recruited. They randomly performed one session of high-intensity, 4 sets x 5 repetitions maximum (5RM), and one session of moderate-intensity, 2 sets x 25 RM. Fatigue was assessed with the Visual Analogue Scale (0-100 mm) before (T0), immediately after (T1) and 24 hours after (T2) each exercise session. Results: Fatigue development from T0 to T1 was significantly lower after 5RM (– 3 ± 18 mm) than after 25RM (5 ± 15 mm), p = 0.004. No difference was seen from T0 to T2 between 5RM (0 ± 17 mm) and 25RM (6 ± 18 mm), p = 0.147. Conclusion: Since the 5RM session did not induce a larger increase in fatigue than the 25RM session, a single session of RT thus appears feasible and safe in patients with pulmonary sarcoidosis irrespective of the RT intensity. The long-term effects of high-intensity RT on fatigue should be explored in a RT program of longer duration.

Background: High-intensity training is comprised of sprint interval training (SIT) and high-intensity interval training (HIIT). This study compared high-intensity training with moderate-intensity continuous training (MICT) on cardiorespiratory fitness (CRF) and body fat percentage for overweight or obese persons. Methods: A systematic search of randomized controlled trials using the health science databases occurred up to April, 2020. Twenty-six studies were included for complete analysis. A total of 784 participations were analyzed. The unstandardized mean difference for each outcome measurement was extracted from the studies and pooled with the random effects model. Results: MICT was significantly better at improving CRF compared with SIT (mean difference = −0.92; 95% confidence interval, −1.63 to −0.21; P = .01; I2 = 10%). Furthermore, there was no significant difference between MICT versus HIIT on CRF (mean difference = −0.52; 95% confidence interval, −1.18 to 0.13; P = .12; I2 = 23%). There was no significant difference in body fat percentage between MICT versus HIIT and MICT versus SIT. Conclusions: MICT was significantly better at improving CRF than SIT in overweight or obese persons.
