Ítem Effect of High-Intensity Interval Training on Body Composition, Cardiorespiratory Fitness, Blood Pressure, and Substrate Utilization During Exercise Among Prehypertensive and Hypertensive Patients With Excessive Adiposity(Frontiers Media S.A., 2020-10) Delgado-Floody, P.; Izquierdo, M.; Ramirez-Velez, R.; Caamano-Navarrete, F.; Moris, R.; Jerez-Mayorga, D.; Andrade D.C.; Alvarez, C.Regular exercise training is a recognized lifestyle strategy to lower resting blood pressure (BP), but little is known about substrate metabolism in population with high BP. Thus, the purpose of this study was to investigate the effects of 16-weeks of HIIT on body composition, BP, cardiorespiratory fitness by (Formula presented.) O2max, and substrate utilization during exercise among prehypertensive and hypertensive patients with excessive adiposity. We also aimed to test the potential association between changes in cardiorespiratory fitness, substrate utilization during exercise and BP. Forty-two physically inactive overweight/obese participants participated in 16-weeks of HIIT intervention. The HIIT frequency was three times a week (work ratio 1:2:10, for interval cycling: rest period: repeated times; 80–100% of the maximum heart rate). Groups were distributed based on their baseline BP: HIIT-hypertensive (H-HTN: age 47.7 ± 12.0 years; body mass index [BMI] 30.3 ± 5.5 kg/m2; systolic [SBP]/diastolic BP [DBP] 151.6 ± 10/81.9 ± 4.2 mmHg), HIIT-pre-hypertensive (H-PreHTN: age 37.6 ± 12.0 years; BMI 31.9 ± 5.3 kg/m2; SBP/DBP 134.4 ± 3.2/74.9 ± 7.0 mmHg), and a normotensive control group (H-CG: age 40.7 ± 11.0 years; BMI 29.5 ± 4.2 kg/m2; SBP/DBP 117.0 ± 6.2/72.4 ± 4.1 mmHg). Anthropometry/body composition, BP, and metabolic substrate utilization during exercise (fat [FATox], carbohydrate [CHOox] oxidation, respiratory exchange ratio [RER], and (Formula presented.) O2max), were measured before and after the 16-week HIIT intervention. Adjusted mixed linear models revealed a significant improved in (Formula presented.) O2max were + 3.34 in the H-CG, + 3.63 in the H-PreHTN, and + 5.92 mL⋅kg–1⋅min–1, in the H-HTN group, however, the Time × Group interaction were not significant (p = 0.083). All the exercise types induced similar decreases on SBP (−8.70) in the H-HTN, (−7.14) in the H-CG, and (−5.11) mmHg in the H-PreHTN, as well as DBP levels (−5.43) mmHg in H-CG group (p = 0.032 vs. H-HTN group). At 16-week, no significant correlations were noted for the changes of blood pressure, cardiorespiratory fitness or exercise metabolism substrates outcomes. In conclusion, our results suggest that a 16-week HIIT-intervention improved (Formula presented.) O2max and blood pressure BP, but these changes are independent of substrate utilization during exercise in normotensive and hypertensive participants with excessive adiposity. © Copyright © 2020 Delgado-Floody, Izquierdo, Ramírez-Vélez, Caamaño-Navarrete, Moris, Jerez-Mayorga, Andrade and Álvarez.Ítem Emergent Anthropometric Indices in Differential Prediction of Prehypertension and Hypertension in Mexican Population: Results according to Age and Sex(Hindawi Limited, 2022-07) Zaragoza-García, O.; Gutiérrez-Pérez, I.; Delgado-Floody, P.; Parra-Rojas, I.; Jerez-Mayorga, D.; Campos-Jara, Ch.; Guzmán-Guzmán, I.Background. Hypertension (HTN) is recognized as a significant public health problem in the world. The objective of this study is to evaluate emergent anthropometric indices as predictors of preHTN and HTN according to age and sex in a sample of Mexican adults. Methods. A cross-sectional study was conducted in 1,150 participants aged 18-80 years old. Anthropometric data and blood pressure measurements were analyzed. Comparisons between men and women were carried out by independent analysis. Cutoff points for each emergent anthropometric index were obtained using the values' upper second and third tertiles. Logistic regression models and receiver operating characteristics curve analyses were used to assess the association and the predictive value of several emergent anthropometric indices with the presence of preHTN and HTN. Results. The prevalence of preHTN and HTN was 29.74% and 14.35%, respectively. In a logistic regression analysis adjusted by age and sex, the body roundness index (BRI) (OR = 2.08, p<0.001) and conicity index (CI) (OR = 1.37, p=0.044) were associated with preHTN, while CI (OR = 2.47, p<0.001) and waist to height squared (W/Ht2) (OR = 2.19, p[removed]40 years old, the predictor indices were W/Ht3 and W/Ht2. In women ≤40 years, the pulse mass index (PMI) was the best main predictor (AUC = 0.909) of HTN. Conclusion. CI, PMI, W/Ht3, W/Ht2, and ABSI could represent differential predictors of preHTN and HTN between men and women according to age range.Ítem Imagen corporal y autoestima en niños según su estado nutricional y frecuencia de actividad física(Sociedad Chilena de Nutrición, Bromatología y Toxicología, 2017) Delgado-Floody, P.; Caamaño, F.; Osorio, A.; Jerez, D.; Fuentes, J.; Levin, E.; Tapia, J.La actividad física juega un papel importante en el desarrollo de los niños. El propósito de este estudio fue comparar según estado nutricional y frecuencia de actividad física la imagen corporal, autoestima, riesgo cardio-metabólico y rendimiento físico de niños. Se estudió 208 niños de 11,9±1,2 años de edad, 115 hombres y 93 mujeres. Quedaron divididos según frecuencia de actividad física a la semana: El Grupo 1 (n= 87) no realizan; Grupo 2 (n= 64) realizan 1 o 2 veces/semana; Grupo 3 (n= 57), realizan 3 o 4 veces/semana. Se observó que 51 niños presentaron sobrepeso y 40 de ellos obesidad. Los niños que realizan 3 o 4 veces actividad física/semana, presentaron menor preocupación por su imagen corporal y puntajes superiores en autoestima, ambas con significancia estadística (p<0,05), además reportaron menor riesgo cardio-metabólico y mejor rendimiento físico. Se concluye que los niños con mayor frecuencia de actividad física/semana, evidencian beneficios en su desarrollo integral.Ítem Intervención integral de ocho meses disminuye el peso y mejora los niveles de depresión y ansiedad en obesos severos y mórbidos(Universidad Nacional de Colombia, 2017) Cofre-Lizama, A.; Delgado-Floody, P.; Angulo-Díaz, P.; Jerez-Mayorga, D.Introduction: Morbid obesity generates a considerable decrease in expectations and quality of life, which causes increased levels of depression and anxiety. Objective: The purpose of this research was to determine the effects of a comprehensive treatment program on weight loss and anxiety and depression levels of severe and morbid obese patients. Materials and methods: 4 men and 12 women with an average age of 34.0±26.0 years, and candidates for bariatric surgery were included in this study. 6 severe obese and 10 morbidly obese patients participated in a comprehensive eight-month treatment intervention. The following conditions were assessed pre- and post-intervention: weight, body mass index (BMI), waist circumference, cardiorespiratory capacity, anxiety and depression. Results: Postoperative weight and BMI decreased significantly (p< 0.001) by 12.28% and 12.30%, respectively, while waist circumference decreased by 11.67% (p< 0.001). In addition, respiratory capacity improved significantly (p< 0.001), and anxiety and depressive symptoms decreased significantly (p< 0.001). Conclusion: The comprehensive eight-month intervention had significant benefits for participants in weight loss and improved levels of anxiety and depression. For this reason, the intervention performed may be recommended for the treatment of this condition.Ítem Is there any relationship between functional movement and weight status? a study in spanish school-age children(ARAN Ediciones S.A., 2018-08) García-Pinillos, F.; Roche-Seruendo, L.E.; Delgado-Floody, P.; Jerez Mayorga, D.; Latorre-Román, P.Á.Background: to examine relations between functional movement patterns and weight status in Spanish primary school children and to determine the differences between sexes. Methods: three hundred and thirty-three, 6-13 years old children (164 boys and 169 girls), participated in this study. The main outcome measures were the body mass index (BMI) and the Functional Movement Screen™ (FMS). Children were classified as normal weight (NW), overweight (OV) or obese (OB) according to international cut-offs. Results: total FMS score was negatively correlated with BMI (p < 0.001). FMS score was different between children from NW, OV and OB groups (p = 0.001), lower with the increased BMI (p < 0.001 between all groups). Significant differences (p < 0.05) between NW, OV and OB were found in deep squat, hurdle step, in-line lunge, shoulder mobility, straight leg-raise and push-up tests. As for the sex differences, girls obtained higher scores (p < 0.05) in in-line lunge, shoulder mobility and straight leg-raise, whereas boys did it in push-up (p = 0.044) test. Conclusions: these results confirm that total FMS score significantly and inversely correlates with BMI in a group of 333 school-age children. As for the sex differences, girls outperform boys in movements requiring flexibility and balance, whilst boys outperform girls in tests where muscular strength is required. © 2018 SENPE and Arán Ediciones S.L.Ítem Obesidad, autoestima y condición física en escolares(Universidad Nacional de Colombia, 2017) Delgado-Floody, P.; Caamaño-Navarrete, F.; Jerez-Mayorga, D.; Cofré-Lizama, A.; Osorio-Poblete, A.; Campos-Jara, C.; Guzmán-Guzmán, I.; Martínez-Salazar, C.; Carcamo-Oyarzun, J.Introduction: Childhood obesity is a serious public health issue, since it generates adverse results for physical and mental health. Objective: To correlate nutritional status and levels of self-esteem and physical performance in schoolchildren aged between 8 and 10. Materials and methods: 236 students participated, 117 male and 119 female, aged between 8 and 10, from two public schools in the municipality of Temuco. Weight, height, body mass index, mass/ fat percentage, waist contour, physical condition, hours of physical exercise per week and self-esteem were evaluated. Results: Overnutrition was documented in 43.6% of the students; children classified as obese (19%) presented higher levels of fat mass and waist contour (p<0.001), and also had a lower physical performance (p<0.05). The hours of physical exercise per week and the level of self-esteem were lower in obese school children, although this figure was not significant (p≥0.05). Conclusions: Obesity in school-aged children reveals alterations associated with physical performance, fat mass and negative trends on self-esteem. Despite developing at an early stage, the consequences associated with this condition can already be seen.Ítem Poor sleep quality decreases concurrent training benefits in markers of metabolic syndrome and quality of life of morbidly obese patients(MDPI AG, 2020-09) Delgado-Floody, P.; Latorre-Roman, P.A.; Jerez-Mayorga, D.; Caamano-Navarrete, F.; Cano-Montoya, J.; Laredo-Aguilera, J.A.; Carmona-Torres, J.M.; Cobo-Cuenca, A.I.; Pozuelo-Carrascosa, D.P.; Alvarez, C.Background: Sleep quality (SQ) plays a role in multiple activities of daily living, but little is known about its role in concurrent training [CT, high-intensity interval (HIIT) plus resistance training (RT)] adaptations for metabolic syndrome (MetS) and health-related quality of life (HRQoL) markers. The aim of the present study was to determine the effects of a 20-week CT programme on MetS and HRQoL markers according to the SQ of morbidly obese patients. Methods: Twenty-nine morbidly obese patients were allocated to one of two groups: good sleep quality (GSQ, n = 15, 38.07 ± 12.26 years) and poor sleep quality (PSQ, n = 14, 40.79 ± 11.62 years). HRQoL, body mass index, waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP, respectively), and plasma outcomes were measured. Results: The GSQ group reported significant changes (pre-vs. post-intervention) in WC (114.0 ± 3.1 vs. 110.4 ± 3.4 cm, p = 0.012), SBP (137.0 ± 4.3 vs. 125.6 ± 1.8 mmHg, p = 0.006), and HRQoL general health (51.33 ± 21.08 vs. 64.33 ± 16.24, p = 0.020). By contrast, the PSQ group showed significant changes only in SQ (9.00 ± 2.42 vs. 5.36 ± 2.84, p = 0.004). Conclusions: Morbidly obese PSQ patients showed a lower response for improving MetS and HRQoL markers after a 20-week CT programme than GSQ peers. However, there was a greater effect size for decreasing WC and SBP in favour of the GSQ compared with the PSQ group, suggesting that there are limitations to CT benefits on these outcomes in the PSQ group. These results call for more complex future studies. © 2020 by the authors.

Therefore, the aim of the present study was to determine lifestyle changes, such as eating habits and physical activity (PA) patterns, caused by confinement during the COVID-19 pandemic and to analyze its association with changes in body weight. Seven hundred participants (women, n = 528 and men, n = 172) aged between 18–62 years old of the Chilean national territory participated in the study. Food habits, PA, body weight, and sociodemographic variables were measured through a survey in May and June 2020. The body weight increase presented positive association with the consumption of fried foods ≥ 3 times per week (OR; 3.36, p < 0.001), low water consumption (OR; 1.58, p = 0.03), and sedentary time ≥6 h/day (OR; 1.85, p = 0.01). Conversely, fish consumed (OR; 0.67, p = 0.03), active breaks (OR; 0.72, p = 0.04), and PA ≥ 4 times per week (OR; 0.51, p = 0.001) presented an inverse association with body weight increase. Daily alcohol consumption (OR; 4.77, p = 0.003) was associated with PA decrease. food habits, PA, and active breaks may be protective factors for weight increase during COVID-19 confinement. © 2020 by the authors.
