El presente estudio de alcance explicativo, realizado bajo un diseño cuasiexperimental de preprueba-posprueba y grupo control, determinó el efecto de un programa de entrenamiento interválico aeróbico de alta intensidad (HIIT) que utilizó juegos motores y circuitos sociomotrices, durante 16 semanas (tres sesiones semanales) para el incremento del consumo de oxígeno pico (VO2pico) y disminución del índice de masa corporal (IMC) y porcentaje de grasa (%GC) en niñas con sobrepeso u obesidad de 10 y 11 años de la sede Marino Dávalos de la Institución Educativa Moderna de Tuluá, distribuidas en dos grupos, experimental (n=8) y control (n=8). Entre los resultados más importantes, se destaca el aumento del VO2pico en 3.6 ml/kg/min, la disminución del IMC en 1.62 y del %GC donde se apreció una disminución del 3.72% en el grupo experimental; mientras que en el grupo control, no se observaron modificaciones estadísticamente significativas; concluyendo el estudio que el programa HIIT que utilizó como medio los juegos motores y circuitos sociomotrices, presentó efectos significativos en el incremento del VO2pico y disminución del IMC y el %GC de las niñas con sobrepeso u obesidad, validando de esta manera la hipótesis de investigación, con niveles de significancia estadística (p< .05) para la prueba de muestras relacionadas (p= .000 para el VO2pico, p=.000 para %GC y p=.000 para IMC). Abstract. The present explanatory scope study, carried out under a quasi-experimental design of pretest-posttest and control group, determined the effect of a high intensity aerobic interval training (HIIT) program that used motor games and sociomotor circuits, for 16 weeks (three sessions weekly) for the increase in peak oxygen consumption (VO2peak) and decrease in body mass index (BMI) and percentage of fat (% GC) in overweight or obese girls of 10 and 11 years of age from the Marino Dávalos headquarters of the Institution Educativa Moderna de Tuluá, divided into two groups, experimental (n = 8) and control (n = 8). Among the most important results, the increase in VO2peak by 3.6 ml/kg/min, the decrease in BMI by 1.62 and the% GC where a decrease of 3.72% was observed in the experimental group stand out; while in the control group, no statistically significant changes were observed; The study concluded that the HIIT program that used motor games and sociomotor circuits as a means, presented significant effects in the increase of the VO2peak and decrease of the BMI and the% GC of the girls with overweight or obesity, thus validating the research hypothesis. , with levels of statistical significance (p <.05) for the test of related samples (p = .000 for VO2peak, p = .000 for % GC and p = .000 for BMI).

A good physical condition is crucial to support achieving maximum performance, so proper training is needed, such as Tabata Training and High Intensity Interval Training. The aims of this study are to examine and analyze the different effects of those training on increasing strength and speed. This study used a "randomized group pretest and posttest design". The population in this study was male students of PKO FIO UNESA 2016, amounting to 160 students. The sampling technique used was random sampling with a sample of 30 students. The 30 students are divided into 3 groups, namely the group of Tabata Training, High Intensity Interval Training and, the control group. This type of research was a quasi-experimental, with a quantitative approach. The data were collected by measuring some techniques, such as measuring strength by using a back and leg dynamometer to measure limb muscle strength and measuring speed by using a 30-meter run. The data were analyzed by using MANOVA technique, with α 0.05.The results showed that the effect of Tabata training toward increasing strength with a value of p = 0.000, the effect Tabata training toward the increasing speed with a value of p = 0.000, then the effect of high intensity interval training toward the increasing strength with a value of p = 0.000, the effect of high intensity interval training toward the increasing speed with a value of p = 0.000. Based on the result of the two trainings result, it concluded that high intensity interval training is better than tabata training in increasing strength and speed.eed.

Introduction Exercise training is strongly recommended as a therapeutic approach to treat individuals with heart failure. High-intensity exercise training modalities still controversial in this population. The study aims to preliminary assess the consequences of high-intensity exercise training modalities, aerobic interval training (HIIT) and progressive high circuit-resistance training (CRT), on primarily endothelial function and cardiorespiratory fitness, and secondly on muscle strength and physical performance in heart failure patients. Methods This preliminary multicentric randomized controlled trial comprised 23 heart failure patients, aged 56 ± 10 years old, mainly New York Heart Association classification I and II (%), hemodynamically stable, who compromise at least 36 exercise sessions of a randomly assigned intervention (HIIT, CRT or control group). Endothelial function, cardiopulmonary exercise testing, muscle strength and physical performance were completed at baseline and post-intervention. Results Although no effects on endothelial function; both HIIT and CRT modalities were able to produce a positive effect on V˙O2 peak (HIIT = +2.1±6.5, CRT = +3.0±4.2 and control group = -0.1± 5.3 mL/kg/min, time*group p-value<0,05) and METs (HIIT = +0.6±1.8, CRT = +0.9±1.2 and control group = 0±1.6, time*group p-value<0,05). Only HIIT increased isokinetic torque peak (HIIT = +8.8±55.8, CRT = 0.0±60.7 and control group = 1.6±57.6 Nm) matched p-value<0,05. Regarding the physical performance, the CRT modality reduced chair stand test completion time (HIIT = -0.7±3.1, CRT = -3.3±3.2 and control group = -0.3±2.5 s, matched p-value<0,05 and HIIT improved global physical performance(time*group p<0,05). Conclusion This preliminary study trends to indicate for the first time that high-intensity interval training promotes a jointly superior effect compared to progressive high intensity circuit-resistance training by improving cardiorespiratory fitness, muscular strength, and physical performance. Further research with larger cohort is necessary. Clinical trial registration number ReBEC RBR-668c8v.

We investigated the effects of 12 weeks of high-intensity interval training (HIIT) on selected circulating adipokines and other cardiovascular diseases risks factors in men with obesity. Thirty men with obesity (age: 24.96 ± 3.11 year, BMI: 30.92 ± 1.04 kg/m2) were randomly assigned to HIIT and control groups. The HIIT group participated in a 12-week HIIT program (5×2 min interval bout at an intensity of 85-95% HRmax interspersed by 1 min passive recovery, three times per week), while the control group maintained their usual lifestyles. Blood lipids, insulin resistance, and select serum adipokines were assessed before and after 12 weeks of the intervention period. HIIT improved body composition and lipid profiles (p<0.05) and also decreased fasting insulin levels (p=0.001) and HOMA-IR (p=0.002) levels. Furthermore, HIIT increased levels of lipocalin-2 (p=0.002) while decreasing omentin-1 levels (p=0.001) in men with obesity. Changes in lcn2 and omentin-1 concentrations correlated with the changes in risk factors in the HIIT group (p<0.05). The results indicate that 12 weeks of supervised HIIT significantly improves both circulating concentrations of lcn2 and omentin-1, two recently described adipokines, and risk markers of cardiovascular diseases in men with obesity. Further research is necessary to understand the molecular mechanisms involved with these changes.

High-intensity aerobic interval training (HIIT) is a compromise between time-consuming moderate-intensity training and sprint-interval training requiring all-out efforts. However, there are few data regarding the ability of HIIT to increase the capacities of fat and carbohydrate oxidation in skeletal muscle. Using untrained recreationally active individuals, we investigated skeletal muscle and whole-body metabolic adaptations that occurred following 6 weeks of HIIT (~1 h of 10 × 4 min intervals at ~90% of peak oxygen consumption (VO2 peak), separated by 2 min rest, 3 d·week–1). A VO2 peak test, a test to exhaustion (TE) at 90% of pre-training VO2 peak, and a 1 h cycle at 60% of pre-training VO2 peak were performed pre- and post-HIIT. Muscle biopsies were sampled during the TE at rest, after 5 min, and at exhaustion. Training power output increased by 21%, and VO2 peak increased by 9% following HIIT. Muscle adaptations at rest included the following: (i) increased cytochrome c oxidase IV content (18%) and maximal activities of the mitochondrial enzymes citrate synthase (26%), β-hydroxyacyl-CoA dehydrogenase (29%), aspartate-amino transferase (26%), and pyruvate dehydrogenase (PDH; 21%); (ii) increased FAT/CD36, FABPpm, GLUT 4, and MCT 1 and 4 transport proteins (14%–30%); and (iii) increased glycogen content (59%). Major adaptations during exercise included the following: (i) reduced glycogenolysis, lactate accumulation, and substrate phosphorylation (0–5 min of TE); (ii) unchanged PDH activation (carbohydrate oxidation; 0–5 min of TE); (iii) ~2-fold greater time during the TE; and (iv) increased fat oxidation at 60% of pre-training VO2 peak. This study demonstrated that 18 h of repeated high-intensity exercise sessions over 6 weeks (3 d·week–1) is a powerful method to increase whole-body and skeletal muscle capacities to oxidize fat and carbohydrate in previously untrained individuals.

AbstractObjectiveThe objective of this study is to examine, based on theory of change, whether integrated leading-managing-and-governing for results model is plausible cause of improved institutional delivery.MethodsA team-based quasi-experimental study was conducted. One-hundred-thirty-four health facility teams were enrolled in the study. Teams were allocated to intervention and control groups in a 1:1 ratio, non-randomly. End line institutional delivery was the dependent variable while the group (main predictor) and the baseline institutional delivery (covariate) were independent variables. The intervention that was given over six months was integrated leading-managing-and-governing for results model. The institutional deliveries were measured with percentages whilst the group was measured with exposure status (yes or no) to the intervention. Data, from both groups, were collected at baseline and end line. Data were analyzed using analysis of covariance. Statistical significance was determined at (p<.05). The main effect of the intervention was determined by 95% CI, presented in the contrast results.ResultsThe adjusted mean institutional deliveries with 95% CI were 47.4 (46.2, 48.6) and 33.4 (32.2, 34.6) in the intervention and control groups, respectively. Contrast results showed that having an intervention group, p = .000, 95% CI (12.2, 15.8), of integrated leading-managing-and governing for results model significantly increased mean institutional delivery compared to having a control group.ConclusionsThis study provides some guidance regarding the plausible causation of integrated leading-managing-and-governing for results model on institutional delivery. It would serve as a baseline in identifying true causation using a randomized design.

To examine the effects of aerobic interval training on the decline in short-passing ability caused by a short bout of high-intensity intermittent activities. For this randomized controlled trial, 26 junior soccer players (mean age, 17.8 ± 0.6 years; mean height, 178 ± 5 cm; mean body mass, 74.5 ± 6.9 kg) were recruited. After baseline measurements, subjects were randomly allocated to 1 of 2 groups: the control group (CG) or the aerobic interval training group (ITG). The ITG completed 4 weeks of high-intensity aerobic training, consisting of 4 bouts of running for 4 min at 90%–95% of maximal heart rate, with 3 min of active recovery between sets, in addition to normal training. Maximum oxygen uptake, Yo-Yo Intermittent Recovery Test level 1 (YYIRT), and short-passing ability (measured using the Loughborough Soccer Passing Test (LSPT)) were measured before and after a 5 min high-intensity simulation (HIS), reproducing the most intense phase of a match. The ITG (n = 11), but not the CG (n = 10), showed a significant 12% and 4% increase in YYIRT and maximal oxygen consumption after training, respectively, and reduced the worsening in LSPT penalty time after the HIS (p < 0.05). The relative exercise intensity during HIS decreased in the ITG only (p < 0.01). Our results demonstrated that junior soccer players may benefit from aerobic training to attenuate the decline in short-passing ability caused by a short bout of intermittent activities completed at the same pretraining workload.

Background and Objectives: Appetite is an essential factor in obesity. The present study aimed to evaluate the effect of High-Intensity Interval Training (HIIT) on GLP-1, appetite, and weight of obese mice while maintaining a high caloric diet. Subjects and Methods A total of 24 C57BL/6 mice with a Mean±SD weight of 20.7±1 g were selected. After implementing a high caloric dieting and making them fat (Mean±SD weight: 30.95±3.23 g), they were divided into two groups of training and control. A high caloric diet was maintained for both groups (training and control) until the end of the experiment, while the training group performed HIIT for 8 weeks. Every session of HIIT included 30 minutes of exercise with a progressive intensity of 50% to 60% in low-intensity intervals and 80% to 90% in high-intensity intervals. The independent t test and analysis of variance with repeated measures were used for data analysis. Results Findings of the study indicated that GLP-1 increased significantly in the HIIT training group compared to the control group (P<0.05). In the HIIT group, body weight was significantly higher (P<0.001), and food intake was significantly lower (P<0.001) than those in the control group. Conclusion When consuming high-calorie food, HIIT training can probably cause weight loss through reducing appetite mediated by increasing GLP-1
