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).

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.

(Wiley, 2023) Ramírez Vélez, Robinson; Izquierdo Redín, Mikel; López Gil, José Francisco; Rincón Pabón, David; Martínez-Jamioy, Edwar Nicolas; Rivera-Ruiz, Rosemberg; Castellanos-Montaña, Sebastián; Atencio Osorio, Miguel Alejandro; Carrillo Arango, Hugo Alejandro; Alonso Martínez, Alicia; García Hermoso, Antonio; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
The aim of the present study was twofold: first, to determine the meeting all three 24-h movement guidelines in Colombian preschool-aged children, and second, to explore the associations between different socio-ecological correlates and the meeting of these guidelines. This was a cross-sectional study with data from the Encuesta Nacional de Situación Nutricional (ENSIN-2015) in Colombia, 2015–2016. The sample comprised 3002 low-income preschoolers (3–4 years old, 50.7% boys). Data on physical activity, screen time, and sleep time were collected using the Cuestionario para la Medición de Actividad Física y Comportamiento Sedentario, reported by their parents. In total, 18 potential correlates (individual, interpersonal, organizational, and community level) were analyzed. Backward binary logistic regression analysis was performed with the potential correlates as independent variables and meeting all three 24-h movement guidelines as dependent variables. The prevalence of preschoolers meeting all three 24-h movement guidelines or none was 4.8% and 16.6%, respectively. In the final model, boys (odds ratio [OR] = 1.87, 95% confidence interval [CI] 1.00–3.50) and those who do not have television in their bedroom (OR = 2.09, 95%CI 1.05–4.14) were more likely to meet all three 24-h movement guidelines compared to with girls and those who have television, respectively. In conclusion, strategies to promote adherence to all 24-h movement guidelines among low-income preschoolers are warranted, and should focus on actions considering the importance of sex and home environment changes to support these movement behaviors.

(MDPI, 2021) Alonso Martínez, Alicia; Ramírez Vélez, Robinson; García Alonso, Yesenia; Izquierdo Redín, Mikel; García Hermoso, Antonio; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua, CENEDUCA1/2019
Background: A better understanding of the effects of the lockdown on lifestyle behaviors may help to guide the public health response to COVID-19 at a national level and to update the global strategy to respond COVID-19 pandemic. The aim of the study was to examine the effects of the COVID-19 lockdown on device-measured physical activity (PA), sedentary time, sleep and self-regulation; and to determine whether PA and sleep are related to self-regulation problems during the lockdown. Methods: PA, sedentary time and sleep were assessed using accelerometry in the week in which the Spanish national state of alarm was declared (n = 21). Parents reported preschooler’s self-regulation difficulties (internalizing and externalizing) before (n = 268) and during the lockdown (n = 157) by a validated questionnaire. Results: Preschoolers showed a decrease in total PA (mean difference [MD] = -43.3 min per day, 95% CI -68.1 to -18.5), sleep efficiency (MD = -2.09%, 95% CI -4.12 to -0.05), an increase in sedentary time (MD = 50.2 min per day, 95% CI 17.1 to 83.3) internalizing (MD = 0.17, 95% CI 0.06 to 0.28) and externalizing (MD = 0.33, 95% CI 0.23 to 0.44) problems. Preschoolers who met the World Health Organization recommendations for PA had lower internalizing scores than non-active peers (MD = -1.28, 95% CI -2.53 to -0.03). Conclusions: Our findings highlight the importance of meeting PA recommendations to reduce psychosocial difficulties during a lockdown situation.

Effects of exercise intervention on health-related physical fitness and blood pressure in preschool children: a systematic review and meta-analysis of randomized controlled trials
(Springer, 2020) García Hermoso, Antonio; Alonso Martínez, Alicia; Ramírez Vélez, Robinson; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
Background: No previous systematic review has quantitatively examined the effect of physical exercise interventions on health-related physical fitness and blood pressure in children younger than 6 years old. Objective: To evaluate the effects of exercise interventions on health-related physical fitness (i.e., physical fitness components and body composition) and blood pressure in preschoolers. Methods: We searched four databases. Only randomized controlled trials (RCTs), evaluating the effectiveness of exercise intervention on weight-related outcomes, blood pressure, and physical fitness components in preschoolers (1–5.99 years old) were included. The effect sizes were reported as Hedges’ g using random-effects models. Results: A total of 19 RCTs were included. Exercise interventions favored reductions in body mass index (g = − 0.17; 95% confidence interval [CI], − 0.31 to − 0.03), waist circumference (g = − 0.25; 95% CI − 0.47 to − 0.03), and body fat percentage (g = − 0.31; 95% CI − 0.60 to − 0.23); as well as improvement in cardiorespiratory fitness (g = 0.25; 95% CI 0.08–0.42), muscular strength (g = 0.25; 95% CI 0.09–0.40), and speed–agility (g = − 0.51; 95% CI − 0.78 to − 0.24). Blood pressure was not reduced. The subgroup analysis revealed that physical exercise alone favored larger reductions in body mass index and waist circumference compared with physical exercise combined with another intervention. Also, changes in cardiorespiratory fitness, lower-body muscular strength and speed–agility were associated with larger decreases in body composition. Conclusion: Physical exercise whether combined or not with additional intervention has a small effect on both body weight and physical fitness in preschoolers. Also, it seems that interventions to prevent obesity should be directed towards improving physical fitness of preschoolers.

Assessing basic motor competences, physical fitness, and executive function in 4-5-year-old children: a longitudinal study in a primary care setting
(BMC, 2024) Legarra Gorgoñón, Gaizka; García Alonso, Yesenia; Ramírez Vélez, Robinson; Alonso Martínez, Loreto; Izquierdo Redín, Mikel; Alonso Martínez, Alicia; Ciencias de la Salud; Osasun Zientziak
Background: To evaluate the progression of physical fitness (PF), basic motor competence (BMC), and executive function (EF) over one year in children aged 4-5 years at a health center. Methods: In this longitudinal analysis, children's BMC was evaluated using the MOBAK KG test for object and self-movement. The PREFIT Battery gauged PF through handgrip strength, standing long jump, and other fitness measures, while the Early Years Toolbox appraised EF. Results: Adjustments for confounding factors showed notable improvements in BMC, particularly in object movement (OM; mean difference 0.789, p=0.044) and self-movement (SM; mean difference 0.842, p=0.037), with overall MOBAK scores also increasing (mean difference 1.632, p=0.018). Enhancements in the standing long jump (mean difference 9.036 cm, p=0.014) and EF tasks "Mr. Ant" (mean difference 0.669, p<0.001) and "Go/No-Go" (mean difference 0.120, p<0.001) were evident, signifying substantial BMC gains and some progress in PF and EF. Conclusion: This research underscores the positive impact of regular training on BMC and PF in young children. Significant BMC development and associated improvements in PF and EF over the study period highlight the importance of structured activities in early childhood. These findings advocate for standardized training programs to enhance childhood health and encourage active lifestyles.

Cardiorespiratory fitness cut-points are related to body adiposity parameters in Latin American adolescents
(MDPI, 2019) Prieto Benavides, Daniel Humberto; García Hermoso, Antonio; Izquierdo Redín, Mikel; Alonso Martínez, Alicia; Agostinis-Sobrinho, César; Correa Bautista, Jorge Enrique; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
Background and Objectives: A deficiency exists in the criterion-referenced cut-points for field-based cardiorespiratory fitness (CRF) in Latin American youths. The aims of the present study were two-fold: (1) To identify the ability of CRF estimated by the 20-m shuttle-run test (20mSRT) to differentiate between 'healthy' and 'unhealthy' phenotypes (by adiposity) in adolescents; (2) to assess the association between obesity and relative peak oxygen uptake (VO2peak) in a large and diverse sample of Latin American youths. In total, 72,505 adolescents aged between 13 and 15 years were recruited from Chile and Colombia (47.5% girls). Materials and Methods: The waist circumference (WC) and waist-to-height ratio (WHtR) were used to identify body adiposity markers. CRF was measured using the 20mSRT (VO2peak). Receiver operating characteristic curves and logistic regression were used to determine the discriminatory ability of CRF to predict body adiposity parameters. Results: For boys and girls, VO2peak showed a significant predictive capacity to detect body fat (area under the curve [AUC] > 0.62). The sensitivity of VO2peak was medium (>63%) for all age- and sex-specific cut-points, with optimal cut-points in 13- to 15-year olds for obesity identified as 43.77 mL·kg-1·min-1 and 38.53 mL·kg-1·min-1 in boys and girls, respectively. Conclusions: According to these cut-points, adolescents with low CRF were more likely to be obese either by WC or WHtR. The CRF cut-points can be used as quantitative markers for a healthier body in Latin American adolescents.

High muscular fitness has a powerful protective cardiometabolic effect in adults: influence of weight status
(BioMed Central, 2016) Ramírez Vélez, Robinson; Correa Bautista, Jorge Enrique; Lobelo, Felipe; Izquierdo Redín, Mikel; Alonso Martínez, Alicia; Rodríguez Rodríguez, Fernando; Cristi Montero, Carlos; Ciencias de la Salud; Osasun Zientziak
Background: Low levels of muscular fitness (MF) are recognized as an important marker of nutritional status and a predictor of metabolic complications, cardiovascular disease and death, however, the relationship between MF, body mass index (BMI) and the subsequent cardiometabolic protective effects has been less studied among Latin American populations. This study identified an association between MF and the cardiometabolic risk score index (CMRSI) and the lipid-metabolic cardiovascular risk index (LMCRI) in a wide sample of university students grouped according to their BMI. Methods: Six thousand ninety five healthy males (29.6 ± 11.7 year-old) participated in the study. Absolute strength was measured using a T.K.K. analogue dynamometer (handgrip), and the participant’s strength was then calculated relative to their body mass (MF/BM). The LMCRI was derived from the levels of triglycerides, low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), and glucose levels in a blood sample. The CMRSI was calculated by summing the standardized residuals (z-score) for waist circumference, total cholesterol, LDL-c, triglycerides, HDL-c, and median blood pressure. Subjects were divided into six subgroups according to BMI (normal vs. overweight/obese) and MF/BM tertiles (unfit, average, fit). Results: The group of participants with low and moderate levels of MF/BM showed higher CMRSI values independent of BMI (P < 0.001). The group with normal BMI and high MF/BM had the highest levels of cardiometabolic protection. All overweight/obese BMI groups had significantly higher LMCRI values independent of the level of MF/BM (P < 0.001). Conclusions: Participants with high MF/BM showed reduced cardiometabolic risk, which increased significantly when they were within normal parameters.

(BMC, 2019) Barbosa, João; Marqués, Mário C.; Izquierdo Redín, Mikel; Neiva, Henrique P.; Barbosa, Tiago M.; Ramírez Vélez, Robinson; Alonso Martínez, Alicia; García Hermoso, Antonio; Aguado Jiménez, Roberto; Marinho, Daniel; Ciencias de la Salud; Osasun Zientziak
Background Schoolbags and the consequences of carrying them, particularly those associated with overload, are often studied as a health concern. Modifications in gait and posture were reported when children carried loads that corresponded to more than 10% of their body weight (BW). The aims of this study were to verify the load that is carried by Portuguese students and how it is influenced by factors such as school grade, school schedule, lunch site, physical education, sex and body mass index (BMI). Acquiring a more specific knowledge of the Portuguese context and understanding the influence of these factors may allow us to generate proposals to control them in ways that benefit students.MethodsThe load carried by students in the 5th grade (10.60.4years) and 9th grade (14.70.6years) were weighed with a luggage scale on all days of the week, resulting in 680 evaluations. Data related to the school day were also collected, such as the student's lunch site, how he or she got to school and his or her school schedule for that day. Individual height and weight were also assessed. Results The 5th grade students carried greater loads than the 9th grade students, resulting in a substantial difference relative to their BW. The school loads of the 5th grade students were mostly greater than 10% of their BWs. Girls tended to carry heavier loads than boys, and overweight students also tended to carry heavier loads. Students who could eat lunch at home carried less weight, and on physical education days, the total load carried increased, but the backpacks of the 5th grade students were lighter.Conclusions The results of the current study describe excessive schoolbag weight among Portuguese students and expound on some of the factors that influence it, which can help researchers and professionals design a solution to decrease children's schoolbag loads.

Association of cardiorespiratory fitness levels during youth with health risk later in life: a systematic review and meta-analysis.
(American Medical Association, 2020-08-31) García Hermoso, Antonio; Ramírez Vélez, Robinson; García Alonso, Yesenia; Alonso Martínez, Alicia; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak; Gobierno de Navarra / Nafarroako Gobernua; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Importance Although the associations between cardiorespiratory fitness (CRF) and health in adults are well understood, to date, no systematic review has quantitatively examined the association between CRF during youth and health parameters later in life. Objectives To examine the prospective association between CRF in childhood and adolescence and future health status and to assess whether changes in CRF are associated with future health status at least 1 year later. Data Sources For this systematic review and meta-analysis, MEDLINE, Embase, and SPORTDiscus electronic databases were searched for relevant articles published from database inception to January 30, 2020. Study Selection The following inclusion criteria were used: CRF measured using a validated test and assessed at baseline and/or its change from baseline to the end of follow-up, healthy population with a mean age of 3 to 18 years at baseline, and prospective cohort design with a follow-up period of at least 1 year. Data Extraction and Synthesis Data were processed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Random-effects models were used to estimate the pooled effect size. Main Outcomes and Measures Anthropometric and adiposity measurements and cardiometabolic health parameters. Results Fifty-five studies were included with a total of 37 563 youths (46% female). Weak-moderate associations were found between CRF at baseline and body mass index (r = –0.11; 95% CI, –0.18 to –0.04; I2 = 59.03), waist circumference (r = –0.29; 95% CI, –0.42 to –0.14; I2 = 69.42), skinfold thickness (r = –0.34; 95% CI, –0.41 to –0.26; I2 = 83.87), obesity (r = –0.15; 95% CI, –0.23 to –0.06; I2 = 86.75), total cholesterol level (r = –0.12; 95% CI, –0.19 to –0.05; I2 = 75.81), high-density lipoprotein cholesterol (HDL-C) level (r = 0.11; 95% CI, 0.05-0.18; I2 = 69.06), total cholesterol to HDL-C ratio (r = –0.19; 95% CI, –0.26 to –0.13; I2 = 67.07), triglyceride levels (r = –0.10; 95% CI, –0.18 to –0.02; I2 = 73.43), homeostasis model assessment for insulin resistance (r = –0.12; 95% CI, –0.18 to –0.06; I2 = 68.26), fasting insulin level (r = –0.07; 95% CI, –0.11 to –0.03; I2 = 0), and cardiometabolic risk (r = –0.18; 95% CI, –0.29 to –0.07; I2 = 90.61) at follow-up. Meta-regression analyses found that early associations in waist circumference (β = 0.014; 95% CI, 0.002-0.026), skinfold thickness (β = 0.006; 95% CI, 0.002-0.011), HDL-C level (β = −0.006; 95% CI, −0.011 to −0.001), triglyceride levels (β = 0.009; 95% CI, 0.004-0.014), and cardiometabolic risk (β = 0.007; 95% CI, 0.003-0.011) from baseline to follow-up dissipated over time. Weak-moderate associations were found between change in CRF and body mass index (r = –0.17; 95% CI, –0.24 to –0.11; I2 = 39.65), skinfold thickness (r = –0.36; 95% CI, –0.58 to –0.09; I2 = 96.84), obesity (r = –0.21; 95% CI, –0.35 to –0.06; I2 = 91.08), HDL-C level (r = 0.05; 95% CI, 0.02-0.08; I2 = 0), low-density lipoprotein cholesterol level (r = –0.06; 95% CI, –0.11 to –0.01; I2 = 58.94), and cardiometabolic risk (r = –0.08; 95% CI, –0.15 to –0.02; I2 = 69.53) later in life. Conclusions and Relevance This study suggests that early intervention and prevention strategies that target youth CRF may be associated with maintaining health parameters in later life.
