Background: There is limited evidence concerning how active commuting (AC) is associated with health benefits in young. The aim of the study was to analyze the relationship between AC to and from campus (walking) and obesity and metabolic syndrome (MetS) in a sample of Colombian university students. Methods: A total of 784 university students (78.6% women, mean age = 20.1 ± 2.6 years old) participated in the study. The exposure variable was categorized into AC (active walker to campus) and non-AC (non/infrequent active walker to campus: car, motorcycle, or bus) to and from the university on a typical day. MetS was defined in accordance with the updated harmonized criteria of the International Diabetes Federation criteria. Results: The overall prevalence of MetS was 8.7%, and it was higher in non-AC than AC to campus. The percentage of AC was 65.3%. The commuting distances in this AC from/to university were 83.1%, 13.4% and 3.5% for < 2 km, 2-5 km and > 5 km, respectively. Multiple logistic regressions for predicting unhealthy profile showed that male walking commuters had a lower probability of having obesity [OR = 0.45 (CI 95% 0.25–0.93)], high blood pressure [OR = 0.26 (CI 95% 0.13–0.55)] and low HDL cholesterol [OR = 0.29 (CI 95% 0.14–0.59)] than did passive commuters. Conclusions: Our results suggest that in young adulthood, a key life-stage for the development of obesity and MetS, AC could be associated with and increasing of daily physical activity levels, thereby promoting better cardiometabolic health.

(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.

(Frontiers Media, 2024-12-18) Ibáñez Pegenaute, Ana; Ortega Moneo, María; Ramírez Vélez, Robinson; Antón Olóriz, María Milagros; Ciencias de la Salud; Osasun Zientziak
In this quasi-experimental before-after trial, we investigated the effects of a high-intensity, low-repetition inspiratory muscle training (HI-LRMT) protocol on respiratory muscle strength in instrumental musicians. In addition, was to estimate the prevalence of “non-responders” (NRs) in terms of muscle force after intervention. Healthy musicians (n = 48) were divided into 2 groups: HI-LRMT (n = 33) and a control group that did not train (CG, n = 15). The intervention training was a high-intensity, low-repetition inspiratory muscle training program using the PowerBreathe® threshold load pressure device, 2 daily sessions of 30 repetitions per session, with a minimum frequency of 5 days per week, for 12 weeks, 5 min per session. The primary outcome measures were maximal inspiratory pressure and expiratory pressure. Change in PImax over 12 weeks for HI-LRMT vs. control was 30.9 (95% CI 25.5–38.3), with the large effect, confirming worthwhile benefits (ηp2 = 0.61). There were significant changes in PEmax 37.3 (95% CI 19.3–48.1), with a large effect size (ηp2 = 0.33). A third of the participants did not demonstrate improvements in terms of muscle force in instrumental musicians. In conclusion, a 12-week high-intensity, low-repetition inspiratory muscle training program using the PowerBreathe® threshold load pressure device, improved inspiratory and expiratory muscle strength in instrumental musicians.

Muscle fitness to visceral fat ratio, metabolic syndrome and ideal cardiovascular health metrics
(MDPI, 2019) Ramírez Vélez, Robinson; Correa Rodríguez, María; Izquierdo Redín, Mikel; Schmidt Río-Valle, Jacqueline; González Jiménez, Emilio; Ciencias de la Salud; Osasun Zientziak
This study aimed to investigate the association between the muscle fitness to visceral fat level (MVF) ratio and the prevalence of metabolic syndrome (MetS) and ideal cardiovascular health (CVH) metrics among college students. A total of 1467 young adults recruited from the FUPRECOL study (Asociación de la Fuerza Prensil con Manifestaciones Tempranas de Riesgo Cardiovascular en Jóvenes y Adultos Colombianos), were categorized into four quartiles based on their MVF ratio. Muscular fitness was assessed using a digital handgrip dynamometer and visceral fat level was determined through bioelectrical impedance analysis. Ideal CVH was assessed, including lifestyle characteristics, anthropometry, blood pressure, and biochemical parameters. The body weight, waist circumference, body mass index (BMI), fat mass, fat mass index, and visceral fat level were significantly higher in subjects in Q1 (lower MVF ratio) than those in Q2, Q3, or Q4 (p < 0.001). The muscle fitness (handgrip and normalized grip strength (NGS)) of the subjects in Q4 was significantly greater than that of those in Q1 to Q2 (p < 0.001). Subjects with a medium-high MVF ratio (i.e., 3–4th quartiles) had an odds ratio of 2.103 of ideal CVH metrics after adjusting for age, gender, university, and alcohol intake (95% confidence interval (CI) 1.832 to 2.414; p < 0.001). A lower MVF ratio is associated with worse CVH metrics and a higher prevalence of MetS in early adulthood, supporting the hypothesis that the MVF ratio could be used as a complementary screening tool that could help clinicians identify young adults with unfavorable levels of CVH and metabolic risk. © 2018 by the authors.

(Arán Ediciones, 2022) Atencio Osorio, Miguel Alejandro; Carrillo Arango, Hugo Alejandro; Ramírez Vélez, Robinson; Ciencias de la Salud; Osasun Zientziak
Objetivo: la condición física es uno de los factores predictores más relevantes del estado de salud mental de un individuo. No obstante, son pocos los estudios que han descrito la relación entre la condición física con síntomas depresivos en universitarios latinos. El objetivo del presente estudio fue verificar la posible relación entre la condición física y los síntomas depresivos en un colectivo de estudiantes universitarios. Métodos y procedimientos de investigación: estudio transversal en 344 universitarios (53 % mujeres) entre los 18 y 25 años (rango 18-23 años), pertenecientes a cuatro instituciones de educación superior de Cali, Colombia. Los síntomas depresivos se recogieron por autoinforme a través del inventario de Depresión Beck-II. Los componentes de la condición física (salto alto, flexiones de brazo, flexiones de tronco y condición aeróbica) se midieron a través de pruebas de campo. El promedio de las 4 variables de condición física se tipifico y transformaron como Z-score para establecer una única variable denominada índice general de condición física. Posteriormente se categorizó en tertiles (T), siendo el tertil (T3) la posición con mejor desempeño físico. Resultados: un 12 % de la población presentó síntomas depresivos leves, mientras que un 10 % presentaron depresión moderada/grave, siendo las mujeres las que acusaron mayor puntaje en el inventario de Depresión Beck-II. En el grupo de hombres, correlaciones inversas y estadísticamente significativas fueron observadas entre los valores de depresión con la escala Beck-II, con el componente de salto alto (Z-score) r = -0,190, la condición aeróbica (Z-score) r = -0,195, y con el índice general de condición física (Z-score) r = -0,189; p < 0,01. Esta misma relación, fue observada tras ajustar por la edad, tabaquismo, enolismo y actividad física semanal como covariable, en los hombres entre los terciles 1 y 3 (p = 0,028). Conclusión: los resultados obtenidos en el presente trabajo revelan que el salto alto y el índice general de condición física de los hombres se relacionan de manera inversa y significativa con el puntaje del inventario de Depresión de Beck-II.

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.

Reliability of health-related physical fitness tests among Colombian children and adolescents: the FUPRECOL study
(Public Library of Science, 2015) Ramírez Vélez, Robinson; Rodrigues Bezerra, Diogo; Correa Bautista, Jorge Enrique; Izquierdo Redín, Mikel; Lobelo, Felipe; Ciencias de la Salud; Osasun Zientziak
Substantial evidence indicates that youth physical fitness levels are an important marker of lifestyle and cardio-metabolic health profiles and predict future risk of chronic diseases. The reliability physical fitness tests have not been explored in Latino-American youth population. This study’s aim was to examine the reliability of health-related physical fitness tests that were used in the Colombian health promotion “Fuprecol study”. Participants were 229 Colombian youth (boys n = 124 and girls n = 105) aged 9 to 17.9 years old. Five components of health-related physical fitness were measured: 1) morphological component: height, weight, body mass index (BMI), waist circumference, triceps skinfold, subscapular skinfold, and body fat (%) via impedance; 2) musculoskeletal component: handgrip and standing long jump test; 3) motor component: speed/agility test (4x10 m shuttle run); 4) flexibility component (hamstring and lumbar extensibility, sit-and-reach test); 5) cardiorespiratory component: 20-meter shuttle-run test (SRT) to estimate maximal oxygen consumption. The tests were performed two times, 1 week apart on the same day of the week, except for the SRT which was performed only once. Intra-observer technical errors of measurement (TEMs) and inter-rater (reliability) were assessed in the morphological component. Reliability for the Musculoskeletal, motor and cardiorespiratory fitness components was examined using Bland–Altman tests. For the morphological component, TEMs were small and reliability was greater than 95% of all cases. For the musculoskeletal, motor, flexibility and cardiorespiratory components, we found adequate reliability patterns in terms of systematic errors (bias) and random error (95% limits of agreement). When the fitness assessments were performed twice, the systematic error was nearly 0 for all tests, except for the sit and reach (mean difference: -1.03% [95% CI = -4.35% to -2.28%]. The results from this study indicate that the “Fuprecol study” health-related physical fitness battery, administered by physical education teachers, was reliable for measuring health-related components of fitness in children and adolescents aged 9–17.9 years old in a school setting in Colombia.

(SAGE, 2022) Gutiérrez Espinoza, Héctor; Araya-Quintanilla, Felipe; Pinto Concha, Sebastián; Sepúlveda Loyola, Walter; Ramírez Vélez, Robinson; Fuentes Contreras, Jorge; Ciencias de la Salud; Osasun Zientziak
Background: The most common complication in the surgery for rotator cuff (RC) tears is postoperative shoulder stiffness. The evidence for the postoperative treatment of this condition is scarce. This study assessed the effects of a postoperative program at the onset of shoulder stiffness following arthroscopic RC repair. Methods: A single-group pre- and post-test design was included. Participants performed a 6-week program. Primary outcomes were shoulder and upper limb function assessed with the Constant–Murley and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaires, respectively. Secondary outcomes included pain intensity at rest and during movement with the visual analog scale (VAS), and shoulder range of motion assessed with a goniometer. Results: A total of 115 adult males were included. The intervention produced a positive effect on the Constant–Murley (+35.6 points, p<0.001) and DASH questionnaire (−26.2 points, p=0.005); VAS at rest (−2.8 cm, p<0.001); VAS at movement (−2.7 cm, p<0.001); and shoulder ROMs. Conclusion: The program showed clinically and statistically significant benefits in most of the functional outcomes in the study participants.

Predictive validity of the body adiposity index in overweight and obese adults using dual-energy X-ray absorptiometry
(MDPI, 2016) Ramírez Vélez, Robinson; Correa Bautista, Jorge Enrique; González-Ruíz, Katherine; Vivas, Andrés; García Hermoso, Antonio; Triana Reina, Héctor Reynaldo; Ciencias de la Salud; Osasun Zientziak
The body adiposity index (BAI) is a recent anthropometric measure proven to be valid in predicting body fat percentage (BF%) in some populations. However, the results have been inconsistent across populations. This study was designed to verify the validity of BAI in predicting BF% in a sample of overweight/obese adults, using dual-energy X-ray absorptiometry (DEXA) as the reference method. A cross-sectional study was conducted in 48 participants (54% women, mean age 41.0 ± 7.3 years old). DEXA was used as the "gold standard" to determine BF%. Pearson¿s correlation coefficient was used to evaluate the association between BAI and BF%, as assessed by DEXA. A paired sample t-test was used to test differences in mean BF% obtained with BAI and DEXA methods. To evaluate the concordance between BF% as measured by DEXA and as estimated by BAI, we used Lin¿s concordance correlation coefficient and Bland-Altman agreement analysis. The correlation between BF% obtained by DEXA and that estimated by BAI was r = 0.844, p < 0.001. Paired t-test showed a significant mean difference in BF% between methods (BAI = 33.3 ± 6.2 vs. DEXA 39.0 ± 6.1; p < 0.001). The bias of the BAI was -6.0 ± 3.0 BF% (95% CI = -12.0 to 1.0), indicating that the BAI method significantly underestimated the BF% compared to the reference method. Lin¿s concordance correlation coefficient was considered stronger (rc = 0.923, 95% CI = 0.862 to 0.957). In obese adults, BAI presented low agreement with BF% measured by DEXA; therefore, BAI is not recommended for BF% prediction in this overweight/obese sample studied.
