Centile reference curves of the ultrasound-based characteristics of the rectus femoris muscle composition in children at 4–11 years old
(Frontiers Media, 2023) García Alonso, Yesenia; Alonso Martínez, Alicia; García Hermoso, Antonio; Legarra Gorgoñón, Gaizka; Izquierdo Redín, Mikel; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
Quantitative diagnostic ultrasound has been proposed as a way to characterize muscle structure, but there is a lack of normative data for children. This study aims to establish age-specific normal ranges for echo-intensity (EI), cross-sectional area (CSA), muscular thickness (MT), and subcutaneous adipose thickness (SAT) values of the rectus femoris muscle in typically developing children. The study recruited 497 children (288 boys and 209 girls) aged 4–10.9 years (mean age 7.39 years), and muscle parameters were measured using 2D B-mode ultrasound. Percentile values and reference curves were calculated using the Lambda, Mu, and Sigma method (LMS). The results showed small variation between measurements for boys compared to girls, with the most significant difference in EI, CSA, and MT values. EI decreased with age, with the most pronounced curve in boys. SAT increased in both sexes, with a slightly higher increase in girls after the age of 9.0 years. This study provides the first age-specific reference norms for the rectus femoris muscle architecture in children, and further research is needed to validate these curves and determine their clinical utility.

(Elsevier, 2016) Ramírez Campillo, Rodrigo; González Jurado, José Antonio; Martínez Salazar, Cristian; Alonso Martínez, Alicia; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
Objectives: To investigate the effects of a six-week plyometric training and creatine supplementation intervention on maximal-intensity and endurance performance in female soccer players during in-season training. Design: Randomized, double-blind, placebo-controlled trial. Methods: Young (age 22.9 ± 2.5 y) female players with similar training load and competitive background were assigned to a plyometric training group receiving placebo (PLACEBO, n = 10), a plyometric training group receiving creatine supplementation (CREATINE, n = 10) or a control group receiving placebo without following a plyometric program (CONTROL, n = 10). Athletes were evaluated for jumping, maximal and repeated sprinting, endurance and change-of-direction speed performance before and after six weeks of training. Results: After intervention the CONTROL group did not change, whereas both plyometric training groups improved jumps (ES = 0.25–0.49), sprint (ES = 0.35–0.41), repeated sprinting (ES = 0.48–0.55), endurance (ES = 0.32–0.34) and change-of-direction speed performance (ES = 0.46–0.55). However, the CREATINE group improved more in the jumps and repeated sprinting performance tests than the CONTROL and the PLACEBO groups. Conclusions: Adaptations to plyometric training may be enhanced with creatine supplementation.

Twenty-four-hour movement guidelines during adolescence and its association with obesity at adulthood: results from a nationally representative study
(Springer, 2022) García Hermoso, Antonio; Ezzatvar, Yasmin; Alonso Martínez, Alicia; Ramírez Vélez, Robinson; Izquierdo Redín, Mikel; López Gil, José Francisco; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
To determine the association between adherence to the 24-h movement guidelines during adolescence with obesity at adulthood 14 years later in a nationally representative cohort. We analyzed data from 6984 individuals who participated in Waves I (1994–1995) and IV (2008–2009) of the National Longitudinal Study of Adolescent Health (Add Health) in the USA. Obesity was defined by the International Obesity Task Force cut-off points at Wave I and adult cut-points at Wave IV (body mass index [BMI]≥30 kg/m2 and waist circumference [WC]≥102 cm in male and 88 cm in female). Physical activity, screen time and sleep duration were self-reported. Adolescents who met screen time recommendation alone (β = −1.62 cm, 95%CI −2.68 cm to −0.56), jointly with physical activity (β = −2.25 cm, 95%CI −3.75 cm to −0.75 cm), and those who met all three recommendations (β = −1.92 cm, 95%CI −3.81 cm to −0.02 cm) obtained lower WC at Wave IV than those who did not meet any of these recommendations. Our results also show that meeting with screen time recommendations (IRR [incidence rate ratio] = 0.84, 95%CI 0.76 to 0.92) separately and jointly with physical activity recommendations (IRR = 0.86, 95%CI 0.67 to 0.97) during adolescence is associated with lower risk of abdominal obesity at adulthood. In addition, adolescents who met all 24-h movement recommendations had lower risk of abdominal obesity later in life (IRR = 0.76, 95%CI 0.60 to 0.97). Conclusion: Promoting the adherence to the 24-h movement guidelines from adolescence, especially physical activity and screen time, seems to be related with lower risk of abdominal obesity later in life, but not for BMI.

Construct validity and test-retest reliability of the International Fitness Scale (IFIS) in Colombian children and adolescents aged 9-17.9 years: the FUPRECOL study
(PeerJ, 2017) Ramírez Vélez, Robinson; Cruz Salazar, Sandra Milena; Martínez, Myriam; Lusa Cadore, Eduardo; Alonso Martínez, Alicia; Correa Bautista, Jorge Enrique; Izquierdo Redín, Mikel; Ortega, Francisco B.; García Hermoso, Antonio; Ciencias de la Salud; Osasun Zientziak
Background: there is a lack of instruments and studies written in Spanish evaluating physical fitness, impeding the determination of the current status of this important health indicator in the Latin population, especially in Colombia. The aim of the study was two-fold: to examine the validity of the International Fitness Scale (IFIS) with a population-based sample of schoolchildren from Bogota, Colombia and to examine the reliability of the IFIS with children and adolescents from Engativa, Colombia. Methods: the sample comprised 1,873 Colombian youths (54.5% girls) aged 9–17.9 years. We measured their adiposity markers (waist-to-height ratio, skinfold thickness, percentage of body fat and body mass index), blood pressure, lipids profile, fasting glucose, and physical fitness level (self-reported and measured). A validated cardiometabolic risk index score was also used. An age- and sex-matched subsample of 229 schoolchildren who were not originally included in the sample completed the IFIS twice for reliability purposes. Results: our data suggest that both measured and self-reported overall physical fitness levels were inversely associated with percentage of body fat indicators and the cardiometabolic risk index score. Overall, schoolchildren who self-reported “good” or “very good” fitness had better measured fitness levels than those who reported “very poor/poor” fitness (all p < 0.001). The test-retest reliability of the IFIS items was also good, with an average weighted kappa of 0.811. Discussion: our findings suggest that self-reported fitness, as assessed by the IFIS, is a valid, reliable, and health-related measure. Furthermore, it can be a good alternative for future use in large studies with Latin schoolchildren from Colombia.

Gamified family-based health exercise intervention to improve adherence to 24-h movement behaviors recommendations in children: "3, 2, 1 Move on Study"
(BMC, 2023) Alonso Martínez, Alicia; Legarra Gorgoñón, Gaizka; García Alonso, Yesenia; Ramírez Vélez, Robinson; Alonso Martínez, Loreto; Erice Echegaray, Blanca; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa; Gobierno de Navarra / Nafarroako Gobernua
Background Evidence suggests that movement patterns, including physical activity, sedentary behavior, and sleep duration, throughout a 24-h period, have a signifcant impact on biological processes and health outcomes for both young and adult populations. However, 80% of adolescents worldwide are not sufciently active, and many children do not meet international physical activity recommendations for their age. Thus, the aim of this study is to evaluate the impact of a 12-week gamifed family-based health and exercise intervention on physical ftness, basic motor competencies, mental and behavioral health, and adherence to 24-h movement guidelines in children aged 4 to 5 years old. The study will evaluate changes in sedentary levels, physical ftness, basic motor competencies, mental and behavioral disorders, adherence to the exercise program, and compliance with physical activity recom‑ mendations. In addition, the aim of this protocol is to describe the scientifc rationale in detail and to provide informa‑ tion about the study procedures. Methods/design A total of 80 children, aged 4 to 5 years old, will be randomly assigned in a 1:1 ratio to one of two groups: the exercise group and the routine care group. The exercise group will undergo a 12-week exercise interven‑ tion, followed by a 12-week follow-up period. On the other hand, the routine care group will undergo a 12-week period of routine care, followed by a 12-week follow-up control period. The exercise program will be implemented in a family setting and facilitated through a gamifed web platform with online supervision, with the hypothesis that it will have a positive impact on physical ftness, anthropometric measures, basic motor competencies, and adherence to 24-h movement guidelines. Discussion The results of this study will provide valuable insights into the impact of a gamifed, family-oriented health and exercise program on various aspects of health, including physical ftness, basic motor competencies, mental and behavioral well-being, and adherence to 24-h movement guidelines. The fndings will contribute to clos‑ ing the gap in current knowledge on the efectiveness of these types of interventions for children and their parents. These fndings will also contribute to the development of future guidelines for promoting physical activity in children

(MDPI, 2019) Amado Pacheco, Julio César; Prieto Benavides, Daniel Humberto; Correa Bautista, Jorge Enrique; García Hermoso, Antonio; Agostinis-Sobrinho, César; Alonso Martínez, Alicia; Izquierdo Redín, Mikel; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
The aim of the study was to assess the feasibility and reliability of physical fitness field tests used in the 'Fuprecol kids' study among Colombian preschool children aged 3-5 years. A total of 90 preschoolers aged 3-5 years participated in the study. Weight, height, waist circumference, cardiorespiratory fitness (CRF), musculoskeletal fitness (handgrip strength and standing broad jump), speed-agility (4 × 10 m shuttle run), and flexibility (sit and reach test) components were tested twice (two weeks apart). The feasibility of the tests (preschoolers able to complete the test) ranged from 96% in the CRF test to 100% in the musculoskeletal fitness, speed-agility, and flexibility tests. Overall, the %TEMs were 0.625% for the weight, 0.378% for the height, 1.035% for the body mass index, and 0.547 % for the waist circumference. In addition, all tests were substantial reliable, for CRF (in stages and laps, concordance correlation coefficient = 0.944 and 0.941, respectively) in both sexes and flexibility (concordance correlation coefficient = 0.949) in girls. There were no significant differences in fitness test-retest mean differences in the boys (P gt; 0.05), except in CRF (laps P = 0.017). In girls, there were differences in CRF (stages (P = 0.017) and laps (P= 0.013)), and flexibility (P = 0.002) variables. The results from this study indicate that the 'Fuprecol kids' battery of tests, administered by physical education teachers, was reliable and feasible for measuring components of physical fitness in preschoolers in a school setting in Colombia.

Effects of exercise training on glycaemic control in youths with type 1 diabetes: a systematic review and meta-analysis of randomised controlled trials
(Taylor & Francis, 2022) García Hermoso, Antonio; Ezzatvar, Yasmin; Huerta Uribe, Nidia; Alonso Martínez, Alicia; Chueca-Guindulain, María J.; Berrade-Zubiri, Sara; Izquierdo Redín, Mikel; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
The aim of the study is to evaluate whether exercise interventions are associated with improved glycaemic control in children and adolescents with type 1 diabetes mellitus (T1DM), and to examine its relationship with the characteristics of the intervention (i.e. type, intensity, length, and duration of the sessions). Eligible criteria were randomised controlled trials of youth aged 6– 18 years with T1DM, participating in an exercise-based intervention where glycaemic control is measured (i.e. glycated haemoglobin [HbA1c]). Pooled effect sizes (Hedges’g) were calculated using random-effects inverse-variance analyses. Fourteen studies enrolling 509 patients were analysed. Effect size was expressed as Hedges’ g to correct for possible small sample bias. Overall, HbA1c levels in the exercise group (g = –0.38 95% confidence interval [CI], –0.66 to –0.11; mean difference [MD] = –0.62%) were reduced compared with the control group. Concurrent training (g = –0.63 95%CI, –1.05 to –0.21), high-intensity exercise (g = –0.43 95%CI, –0.83 to –0.03), interventions ≥24 weeks (g = –0.92 95%CI, –1.44 to –0.40), and sessions ≥60 minutes (g = –0.71 95%CI, –1.05 to –0.08) showed larger changes (MD = –0.66% to 1.30%). In conclusion, our study suggests that programmes longer than 24 weeks with at least 60 min/session of high-intensity concurrent exercise may serve as a supportive therapy to metabolic control in youth with T1DM.

Evaluación de los dominios de la actividad física y los componentes de la condición física en niños de 4-5 años en un centro de salud
(Lúa Ediciones 3.0, 2023) Legarra Gorgoñón, Gaizka; García Alonso, Yesenia; Ramírez Vélez, Robinson; Erice Echegaray, Blanca; Moreno González, Paula; Izquierdo Redín, Mikel; Alonso Martínez, Alicia; Ciencias de la Salud; Osasun Zientziak
Introducción: la falta de actividad física y el sedentarismo en niños se asocia con una mayor adiposidad, bajo nivel de aptitud cardiovascular y riesgo de enfermedades cardiovasculares. Sin embargo, cumplir con las recomendaciones de actividad física se relaciona con mejoras en la salud mental, disminución de la ansiedad y depresión, así como adopción de hábitos saludables. Objetivos: evaluar la relación entre los diferentes dominios de la actividad física y del sedentarismo, medidos de forma objetiva, y los componentes de la condición física en niños españoles de 4 y 5 años. Población y métodos: estudio transversal dentro del proyecto 'Observatorio y programa de intervención de ejercicio físico y estilos de vida en familia para niños y niñas de 4 a 5 años en Atención Primaria' (https://observatorioactividadfisica.es). La condición física se evaluó con la batería PREFIT y la cantidad e intensidad de actividad física mediante un acelerómetro tri-axial GENEActiv durante 7 días consecutivos las 24 horas del día. Resultados: la muestra evaluada fue de 70 niños (38 niños y 32 niñas) con una media (intervalo de confianza [IC] del 95%) de 4,83 años. No se observaron diferencias significativas en la condición física entre niños y niñas. Los niños realizaron una actividad física de mayor intensidad y tiempo que las niñas. Además, se encontró una fuerte relación significativa entre los componentes de la condición física y los dominios de la actividad física. Conclusiones: estos hallazgos resaltan la importancia de promover estilos de vida activos desde temprana edad y la necesidad de programas de entrenamiento estructurado para reducir el sedentarismo y mejorar la condición física en esta población.

Normative reference values for the 20 m shuttle-run test in a population-based sample of school-aged youth in Bogota, Colombia: the FUPRECOL study
(Wiley, 2017) Ramírez Vélez, Robinson; Palacios López, Adalberto; Prieto Benavides, Daniel Humberto; Correa Bautista, Jorge Enrique; Izquierdo Redín, Mikel; Alonso Martínez, Alicia; Ciencias de la Salud; Osasun Zientziak
Objectives: Our aim was to determine the normative reference values of cardiorespiratory fitness (CRF) and to establish the proportion of subjects with low CRF suggestive of future cardio‐metabolic risk. Methods: A total of 7244 children and adolescents attending public schools in Bogota, Colombia (55.7% girls; age range of 9–17.9 years) participated in this study. We expressed CRF performance as the nearest stage (minute) completed and the estimated peak oxygen consumption (V˙O2peak). Smoothed percentile curves were calculated. In addition, we present the prevalence of low CRF after applying a correction factor to account for the impact of Bogota's altitude (2625 m over sea level) on CRF assessment, and we calculated the number of participants who fell below health‐related FITNESSGRAM cut‐points for low CRF. Results: Shuttles and V˙O2peak were higher in boys than in girls in all age groups. In boys, there were higher levels of performance with increasing age, with most gains between the ages of 13 and 17. The proportion of subjects with a low CRF, suggestive of future cardio‐metabolic risk (health risk FITNESSGRAM category) was 31.5% (28.2% for boys and 34.1% for girls; X2 P = .001). After applying a 1.11 altitude correction factor, the overall prevalence of low CRF was 11.5% (9.6% for boys and 13.1% for girls; X2 P = .001).

(MDPI, 2021) Álvarez, Cristian; Paredes-Arévalo, Lorena; Obando, Isabel; Leal, Marlys; Ávila, Yennifer; Sadarangani, Kabir P.; Delgado Floody, Pedro; Alonso Martínez, Alicia; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
Reduced sleep duration in schoolchildren has been associated with poor health outcomes at the scholar level; however, there is little information on the effects of sleep loss on Chilean preschoolers. The aim of this study was to describe and compare cardiometabolic outcomes according with the sleep duration in Chilean preschoolers. A second aim was to identify potential risk outcomes (i.e., in odds ratios) for suffering anthropometric and body composition alterations related with participants' sleep duration. A total of 99 (n = 54 boys; n = 45 girls) preschoolers (mean age (95% CI) 3.1 (2.7, 3.4 years), mean weight 16.1 (15.5, 16.6 kg)) were included in this study. Sleep duration was assessed using standardized questionnaires with the parents. Socio-demographic parents’ information, as well as anthropometric, nutritional, and handgrip strength outcomes in preschoolers were distributed by tertiles (T1; < 10 h, T2; 10 to < 11 h, and T3; ≥ 11 h) of sleep time. Children in the lowest tertile of sleep duration had significantly higher body mass indices (p = 0.036), weight-for-height Z-scores (p < 0.0001), waist–hip ratios (p = 0.041), and body fat in percent (p = 0.035) and kg (p = 0.044) compared to those in the top tertile. Low sleep duration was associated with significantly greater risks of overweight/obesity (OR 1.3 (0.9, 1.8)), low height (OR 1.2 (0.8, 1.6)), and increased BMI (OR 1.5 (0.4, 1.4)), but not with reductions in grip strength. Chilean preschoolers with low sleep duration showed higher cardiometabolic markers (anthropometric/body composition) and were more likely to be classified as obese than youth with longer sleep duration.
