    Background: Postexercise hypotension (PEH) is a common physiological phenomenon occurring immediately after endurance training (ET), resistance training (RT), and ET plus RT, also termed concurrent training (CT); however, there is little knowledge about the interindividual and magnitude response of PEH in morbidly obese patients. Aim: The aims of this study were (1) to investigate the effect of CT order (ET + RT vs. RT + ET) on the blood pressure responses; 2) characterize these responses in responders and nonresponders, and 3) identify potential baseline outcomes for predicting blood pressure decreases as responders. Methods: A quasi-experimental study developed in sedentary morbidly obese men and women (age 43.6 ± 11.3 years; body mass index [BMI] ≥40 kg/m2) was assigned to a CT group of ET plus RT (ET + RT; n = 19; BMI 47.8 ± 16.7) or RT plus ET order group (RT + ET; n = 17; BMI 43.0 ± 8.0). Subjects of both groups received eight exercise sessions over four weeks. Primary outcomes include systolic (SBP), diastolic (DBP), mean arterial pressure [MAP], heart rate at rest [HR], and pulse pressure [PP] measurements before and after 10 min post-exercise. Secondary outcomes were other anthropometric, body composition, metabolic, and physical fitness parameters. Using the delta ∆SBP reduction, quartile categorization (Q) in “high” (Rs: quartile 4), “moderate” (MRs: quartile 3), “low” (LRs: quartile 2), and “nonresponders” (NRs: quartile 1) was reported. Results: Significant pre–post changes were observed in ET + RT in session 2 for SBP (131.6 vs. 123.4 mmHg, p = 0.050) and session 4 (131.1 vs. 125.2 mmHg, p = 0.0002), while the RT + ET group showed significant reductions in session 4 (134.2 vs. 125.3 mmHg, p < 0.001). No significant differences were detected in the sum of the eight sessions for SBP (∑∆SBP) between ET + RT vs. RT + ET (−5.7 vs. −4.3 mmHg, p = 0.552). Interindividual analyses revealed significant differences among frequencies comparing Q1 “NRs” (n = 8; 22.2%), Q2 “LRs” (n = 8; 22.2%), Q3 “MRs” (n = 9; 25.0%), and Q4 “HRs” (n = 11; 30.5%), p < 0.0001. Quartile comparisons showed significant differences in SBP changes (p = 0.035). Linear regression analyses revealed significant association between ∑∆SBP with body fat % (β –3.826, R2 0.211 [21.1%], p = 0.031), skeletal muscle mass [β –2.150, R2 0.125 (12.5%), p = 0.023], fasting glucose [β 1.273, R2 0.078 (7.8%), p = 0.003], triglycerides [β 0.210, R2 0.014 (1.4%), p = 0.008], and the 6-min walking test [β 0.183, R2 0.038 (3.8%), p = 0.044]. Conclusion: The CT order of ET + RT and RT + ET promote a similar ‘magnitude’ in the postexercise hypotensive effects during the eight sessions of both CT orders in 4 weeks of training duration, revealing “nonresponders” and ‘high’ responders that can be predicted from body composition, metabolic, and physical fitness outcomes.

    (Frontiers Media S.A., 2022-09-23) Delgado Floody, Pedro; Chirosa Ríos, Luis; Caamaño Navarrete, Felipe; Valdés Badilla, Pablo; Herrera Valenzuela, Tomás; Monsalves Álvarez, Matías; Núñez Espinosa, Cristian; Castro Sepulveda, Mauricio; Guzmán Muñoz, Eduardo; Andrade, David C.; Álvarez, Cristian
    The non-responders (NRs) after exercise training have been poorly studied in populations with morbid obesity. The purpose of this study was to determine the NR prevalence after 20 weeks of concurrent training of morbidly obese women with a high or low number of metabolic syndrome (MetS) risk factors. Twenty-eight women with morbid obesity participated in an exercise training intervention and were allocated into two groups distributed based on a high (≥3, n = 11) or low number (<3, n = 17) of MetS risk factors. The main outcomes were waist circumference (WC), fasting plasma glucose (FPG), high-density lipids (HDL-c), triglycerides (Tg), and systolic (SBP) and diastolic (DBP) blood pressure, and secondary outcomes were body composition, anthropometric and physical fitness, determined before and after 20 weeks of concurrent training. NRs were defined as previously used technical error cut-off points for the MetS outcomes. Significantly different (all p < 0.05) prevalences of NRs between the H-MetS vs. L-MetS groups (respectively) in WC (NRs 18.2 % vs. 41.1 %, p < 0.0001), SBP (NRs 72.7 % vs. 47.0 %, p = 0.022), DBP (NRs 54.5 % vs. 76.4 %, p < 0.0001), FPG (NRs 100% vs. 64.8 %, p < 0.0001), and HDL-c (NRs 90.9 % vs. 64.7 %, p = 0.012) were observed. In addition, the H-MetS group evidenced significant changes on ΔSBP (−10.2 ± 11.4 mmHg), ΔFPG (−5.8 ± 8.2 mg/dl), ΔHDL-c (+4.0 ± 5.9 mg/dl), and ΔTg (−8.8 ± 33.8 mg/dl), all p < 0.05. The L-MetS group only showed significant changes in ΔWC (−3.8 ± 5.0 cm, p = 0.009). Comparing H-MetS vs. L-MetS groups, significant differences were observed in ∆FPG (−5.8 ± 8.2 vs. +0.3 ± 3.2 mg/dl, p = 0.027), but not in other MetS outcomes. In conclusion, 20 weeks of concurrent training promotes greater beneficial effects in morbidly obese patients with a high number of MetS risk factors. However, the NR prevalence for improving MetS outcomes was significantly superior in these more-diseased groups in SBP, FPG, and HDL-c, independent of their major training-induced effects.

    Dissatisfaction with body image and its relation to nutritional status, cardiometabolic risk and cardiorespiratory capacity in public school children
    (Grupo Aula Medica S.A., 2017) Delgado Floody, Pedro; Martínez Salazar, Cristian; Caamaño Navarrete, Felipe; Jerez Mayorga, Daniel; Osorio Poblete, Aldo; García Pinillos, Felipe; Latorre Román, Pedro
    Introduction: The increase in abdominal fat and excess weight are related to dissatisfaction with body image, which nowadays is highly prevalent nationally and internationally. Aim: The purpose of the study was to relate dissatisfaction levels to body image, nutritional status, cardiometabolic risk and cardiorespiratory capacity in pre-adolescent students. Material and methods: Three hundred and thirty-nine students participated in the study, 165 girls (11.29 ± 0.69 years) and 174 boys (11.22 ± 0.72 years). Anthropometric data were collected: BMI, percentage of body fat (%BF), waist circumference (WC), height-to-weight ratio (HWR), VO2max and body image. Results: In the comparison by sex, we found higher VO2max values in boys (p < 0.001). No significant differences were found for the variables BMI, WC, HWR, blood pressure and body image (p > 0.05); 27.7% of the study sample were overweight and 29.2% were obese. The subjects with obesity had the lowest VO2max levels. Dissatisfaction with body image was found to be associated with nutritional status (p < 0.001). In addition, 8.1% of the obese students presented extreme dissatisfaction with their body image and 19.4% of the children with cardiometabolic risk exhibited some type of dissatisfaction; the two variables were related (p = 0.008). Conclusions: The study provides evidence that children with malnutrition by excess present disorders associated with body dissatisfaction and other health indicators that limit integral growth in pre-adolescence. © 2017, Grupo Aula Medica S.A.

    Healthy lifestyles and physical fitness are associated with abdominal obesity among Latin-American and Spanish preschool children: A cross-cultural study
    (John Wiley and Sons Ltd, 2022-07) Latorre Román, Pedro Ángel; Guzmán Guzmán, Iris Paola; Antonio Párraga Montilla, Juan; Caamaño Navarrete, Felipe; Salas Sánchez, Jesús; Palomino Devia, Constanza; Reyes Oyola, Felipe Augusto; Álvarez, Cristian; de la Casa Pérez, Ana; Cardona Linares, Antonio J.; Delgado Floody, Pedro
    Background: Identifying environmental factors that influence health in children are necessary to develop preventive strategies. Objective: To determine the association between the lifestyles of children (i.e., Mediterranean diet (MD), physical activity (PA), fitness and screen time (ST) with abdominal obesity (AO) of preschoolers from three Spanish-speaking countries (Chile, Colombia and Spain) with different socioeconomic levels and Human Development Index (HDI) indicators. Material and Methods: This cross-sectional study included 982 schoolchildren (aged 4–6 years; 56.8% girls) from Chile (n = 409), Colombia (n = 281), and Spain (n = 292). Body mass index (BMI), waist circumference (WC), waist-to-height ratio (WtHR), adherence to the MD, PA, ST and physical fitness were evaluated. Results: Spanish preschoolers reported a lower WtHR (p < 0.001), greater physical fitness (Z-score) (p < 0.001) and higher adherence to the MD (p < 0.001) than their Chilean and Colombian peers. In addition, Colombian preschoolers had a better lifestyle (PA + ST) than their Chilean and Spanish peers (p < 0.001). Chilean preschoolers reported a higher prevalence of AO than the Spanish preschoolers (65% vs. 51.9%; p = 0.001). Conclusion: Lifestyle had a significant association with AO among Spanish-speaking preschool children, with physical fitness especially being a relevant factor regardless of the country of origin. The findings of the current study may support the development of public guidelines focusing on healthy lifestyles in children to create effective plans that contribute to the early treatment of AO in preschool children. © 2022 The Authors.

    The Effects of Two Different Concurrent Training Configurations on Markers of Metabolic Syndrome and Fitness in Women With Severe/Morbid Obesity: A Randomised Controlled Trial
    (Frontiers Media S.A., 2021-09) Delgado Floody, Pedro; Soriano Maldonado, Alberto; Rodríguez Pérez, Manuel A; Latorre Román, Pedro Ángel; Martínez Salazar, Cristian; Vargas, Claudia Andrea; Caamaño Navarrete, Felipe; Jerez Mayorga, Daniel; Álvarez, Cristian
    Concurrent training (CT), characterised by combining both aerobic and resistance training modalities within the same session, is recognised to improve metabolic syndrome (MetS) markers, but little is known about the effects of different configurations (i.e., order) of these exercise modalities on MetS markers and the interindividual responses. The purpose of the present study was to describe the effects, and the interindividual variability, of 20weeks of two CT configurations (i.e., high intensity interval training (HIIT) plus resistance training (RT), compared with RT plus HIIT) in women with severe/morbid obesity. Overall, 26 women with severe/morbid obesity were assigned either to HIIT+RT [n=14, mean and 95%CI, 45.79 (40.74; 50.83) or RT+HIIT (n=12), 33.6 (25.30; 41.79) years]. MetS-related outcomes were waist circumference (WC, cm), systolic (SBP, mmHg) and diastolic (DBP, mmHg) blood pressure, high-density lipoprotein cholesterol (HDL-c), triglycerides (Tg), and fasting plasma glucose (FPG). Secondary outcomes were other anthropometrics, body composition, lipids, muscle strength, and the six-minute walk test (6Mwt). There were significant differences in the prevalence of nonresponders (NRs) only for WC comparing HIIT+RT 2 (18.1%) vs. RT+HIIT group 5 (50.0%), p[removed]0.05. Additionally, the RT+HIIT group showed significant reductions in WC (∆ –3.84cm, p=0.015), SBP (∆ –8.46mmHg, p=0.040), whereas the HIIT+RT group elicited significant reductions only in SBP (∆ –8.43mmHg, p=0.022). The HIIT+RT promoted a lower prevalence of NRs than the RT+HIIT configuration on WC, and overall, there were slightly more beneficial training-induced effects on markers of MetS in the RT+HIIT group compared to the HIIT+RT group. © Copyright © 2021 Delgado-Floody, Soriano-Maldonado, Rodríguez-Pérez, Latorre-Román, Martínez-Salazar, Vargas, Caamaño-Navarrete, Jerez-Mayorga and Álvarez.
