    Frecuencia de zancada durante la carrera de resistencia en tapiz rodante y al aire libre
    (Federación Española de Asociaciones de Docentes de Educación Física (FEADEF), 2024-08-03) Miqueleiz Erburu, Unai; Cabello Olmo, Miriam; Aguado Jiménez, Roberto; Ciencias de la Salud; Osasun Zientziak
    Los objetivos fueron i) estudiar la concordancia entre un reloj deportivo (Suunto Ambit2) y un sistema fotoeléctrico (Optogait) como instrumento referencia para medir la frecuencia de zancada (FZ) y la longitud de zancada (LZ); ii) observar las FZ y LZ durante la carrera al aire libre; y iii) analizar el efecto de la manipulación de la FZ en la economía de carrera monitorizada por un analizador de gases en función de las FZ encontradas en el análisis observacional. Ciento-sesenta corredores fueron analizados entre 8-14 km·h-1. El dispositivo Suunto Ambit2 concordó con el sistema de referencia en la medición de la FZ y la LZ [r=0.99 (0.99-1.00); Error Típico de la Estimación=0.58 zancadas∙min-1 y 0.02m]. Los corredores mantuvieron una FZ constante [Coeficiente de Variación (CV)=2.4%] aun cuando hubo variaciones en la velocidad (CV=6.8%), y dependieron de la LZ (CV=6.5%) durante las carreras al aire libre. Por último, los corredores mantuvieron un bajo coste de carrera con su FZ autoseleccionada (media=81.3 zancadas∙min-1), aunque un incremento hasta el 12% podría ser beneficioso cuando la velocidad varía sin detrimento en el coste de carrera.

    Schoolbag weight carriage in Portuguese children and adolescents: a cross-sectional study comparing possible influencing factors
    (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.

    Heat dissipating upper body compression garment: thermoregulatory, cardiovascular, and perceptual responses
    (Elsevier, 2019) Leoz Abaurrea, Iker; Tam, Nicholas; Aguado Jiménez, Roberto; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
    Purpose: The aim of the present study was to determine the effects of an upper body compression garment (UBCG) on thermoregulatory responses during cycling in a controlled laboratory thermoneutral environment (~23°C).A secondary aim was to determine the cardiovascular and perceptual responses when wearing the garment. Methods: Sixteen untrained participants (age: 21.3 ± 5.7 years; peak oxygen consumption (VO2peak): 50.88 ± 8.00 mL/min/kg; mean ± SD) performed 2 cycling trials in a thermoneutral environment (~23°C) wearing either UBCG or control (Con) garment. Testing consisted of a 5 min rest on a cycle ergometer, followed by 4 bouts of cycling for 14 min at ~50%VO2peak, with 1 min rest between each bout. At the end of these bouts there was 10 min of passive recovery. During the entire protocol rectal temperature (Trec), skin temperature (Tskin), mean body temperature (Tbody), and heat storage (HS) were measured. Heart rate (HR), VO2, pH, hematocrit (Hct), plasma electrolytes, weight loss (Wloss), and perceptual responses were also measured. Results: There were no significant differences between garments for Tskin, HS, HR, VO2, pH, Hct, plasma electrolyte concentration, Wloss, and perceptual responses during the trial. Trec did not differ between garment conditions during rest, exercise, or recovery although a greater reduction in Trec wearing UBCG (p = 0.01) was observed during recovery. Lower Tbody during recovery was found when wearing UBCG (36.82°C ± 0.3°C vs. 36.99°C ± 0.24°C). Conclusion: Wearing a UBCG did not benefit thermoregulatory, cardiovascular, and perceptual responses during exercise although it was found to lower Tbody during recovery, which suggests that it could be used as a recovery tool after exercise.

    Consistency of sex-based differences between treadmill and overground running using an inertial measurement unit (IMU)
    (Elsevier, 2024-06-19) Miqueleiz Erburu, Unai; Aguado Jiménez, Roberto; Lecumberri Villamediana, Pablo; Gorostiaga Ayestarán, Esteban; Ciencias de la Salud; Osasun Zientziak; Universidad Publica de Navarra / Nafarroako Unibertsitate Publikoa
    Differences in running gait between treadmill and overground running has been subject of study, while consistency of group differences between running surfaces has not been previously analysed. This study examined both the differences between running surfaces and the consistency of sex-based differences between surfaces in some spatiotemporal and kinematic variables measured by an inertial measurement unit fastened over the lumbar spine. Thirty-two (sixteen females) endurance runners firstly performed overground and then treadmill (1 % inclination) runs at speeds between 9-21 km.h-1. Males showed lower flight time (FT) [moderate effect size (ES)] during treadmill running compared to overground, while females showed greater stride frequency (SF) (moderate ES), lower stride length (SL) (moderate ES), FT (moderate ES), and vertical (VT) trunk displacement (moderate ES), as well as greater medio-lateral (ML) trunk displacement (moderate ES). No differences in CT between surfaces were found (trivial to small). Furthermore, all the sex-differences were consistent between treadmill and overground running: Males showed lower SF (large and moderate ES, respectively), greater SL (large and moderate ES) and CT (moderate and large ES), lower FT (large ES), greater VT displacement (moderate to large ES), and lower ML displacement (moderate ES) than females. These results may be of interest to carefully transfer the running gait analyses between surfaces depending on sex.

    Elovanoids counteract inflammatory signaling, autophagy, endoplasmic reticulum stress, and eenescence gene programming in human nasal epithelial cells exposed to allergens
    (MDPI, 2022) Resano Lizaldre, Alfredo; Bhattacharjee, Surjyadipta; Barajas Vélez, Miguel Ángel; Do, Khanh V.; Aguado Jiménez, Roberto; Rodríguez, David; Palacios Peláez, Ricardo; Bazán, Nicolás G.; Ciencias de la Salud; Osasun Zientziak
    To contribute to further understanding the cellular and molecular complexities of inflammatory-immune responses in allergic disorders, we have tested the pro-homeostatic elovanoids (ELV) in human nasal epithelial cells (HNEpC) in culture challenged by several allergens. ELV are novel bioactive lipid mediators synthesized from the omega-3 very-long-chain polyunsaturated fatty acids (VLC-PUFA,n-3). We ask if: (a) several critical signaling events that sustain the integrity of the human nasal epithelium and other organ barriers are perturbed by house dust mites (HDM) and other allergens, and (b) if ELV would participate in beneficially modulating these events. HDM is a prevalent indoor allergen that frequently causes allergic respiratory diseases, including allergic rhinitis and allergic asthma, in HDM-sensitized individuals. Our study used HNEpC as an in vitro model to study the effects of ELV in counteracting HDM sensitization resulting in inflammation, endoplasmic reticulum (ER) stress, autophagy, and senescence. HNEpC were challenged with the following allergy inducers: LPS, poly(I:C), or Dermatophagoides farinae plus Dermatophagoides pteronyssinus extract (HDM) (30 µg/mL), with either phosphate-buffered saline (PBS) (vehicle) or ELVN-34 (500 nM). Results show that ELVN-34 promotes cell viability and reduces cytotoxicity upon HDM sensitization of HNEpC. This lipid mediator remarkably reduces the abundance of pro-inflammatory cytokines and chemokines IL-1β, IL-8, VEGF, IL-6, CXCL1, CCL2, and cell adhesion molecule ICAM1 and restores the levels of the pleiotropic anti-inflammatory IL-10. ELVN-34 also lessens the expression of senescence gene programming as well as of gene transcription engaged in pro-inflammatory responses. Our data also uncovered that HDM triggered the expression of key genes that drive autophagy, unfolded protein response (UPR), and matrix metalloproteinases (MMP). ELVN-34 has been shown to counteract these effects effectively. Together, our data reveal a novel, pro-homeostatic, cell-protective lipid-signaling mechanism in HNEpC as potential therapeutic targets for allergies.

    Reliability of Xsens inertial measurement unit in measuring trunk accelerations: a sex-based differences study during incremental treadmill running
    (Frontiers Media, 2024) Miqueleiz Erburu, Unai; Aguado Jiménez, Roberto; Lecumberri Villamediana, Pablo; García Tabar, Ibai; Gorostiaga Ayestarán, Esteban; Ciencias de la Salud; Osasun Zientziak
    Introduction: Inertial measurement units (IMUs) are utilized to measure trunk acceleration variables related to both running performances and rehabilitation purposes. This study examined both the reliability and sex-based differences of these variables during an incremental treadmill running test. Methods: Eighteen endurance runners performed a test–retest on different days, and 30 runners (15 females) were recruited to analyze sex-based differences. Mediolateral (ML) and vertical (VT) trunk displacement and root mean square (RMS) accelerations were analyzed at 9, 15, and 21 km·h−1. Results: No significant differences were found between test-retests [effect size (ES)<0.50)]. Higher intraclass correlation coefficients (ICCs) were found in the trunk displacement (0.85-0.96) compared to the RMS-based variables (0.71–0.94). Male runners showed greater VT displacement (ES = 0.90–1.0), while female runners displayed greater ML displacement, RMS ML and anteroposterior (AP), and resultant euclidean scalar (RES) (ES = 0.83–1.9). Discussion: The IMU was found reliable for the analysis of the studied trunk acceleration-based variables. This is the first study that reports different results concerning acceleration (RMS) and trunk displacement variables for a same axis in the analysis of sex-based differences.
