Ítem Análisis del efecto de la pretemporada en los parámetros morfológicos y fisiológicos en remo tradicional femenino. Traineras(Consejo General de Colegios Oficiales de Licenciados en Educación Física y en Ciencias de la Actividad Física y del Deporte de España, 2024) Larrinaga García, Beñat; Santisteban Leguina, Aitor; Catañeda Babarro, Arkaitz; Coca Núñez, Aitor; Arbillaga Etxarri, AneEste estudio descriptivo tiene como objetivo dual el establecer valores específicos inéditos en la modalidad de traineras y, por otro lado, examinar los cambios morfológicos y fisiológicos durante la pretemporada en remeras mediante una valoración pre-post. Participaron 22 remeras de remo tradicional con una edad de 24,69 ± 4,26 años y una experiencia de 5,73 ± 4,55, sometiéndose a pruebas de composición corporal y de ergometría en dos momentos, de la pretemporada, la evaluación denominada “pre” se realizó a mediados de enero, durante el periodo preparatorio de la pretemporada y tras un entrenamiento controlado de 19 semanas se realizó la medición denomina “post” justo antes del inicio del periodo competitivo. Tras la valoración pre-post, se mostró que el entrenamiento físico aplicado durante la pretemporada mediante el programa combinado de resistencia aeróbica y entrenamiento de la fuerza es efectivo para obtener cambios significativos (p < 0,05) pen la composición corporal con bajada de la masa grasa de 14,40 ± 4,49 a 13,40 ± 3,41 y aumentando el porcentaje de masa muscular de 42,90% a 43,70%. A su vez, las mejoras en parámetros fisiológicos reflejaron un aumento en la potencia máxima de 341W a 368W, Potencia aeróbica máxima de 170W a 186 W así como en su valor relativo y la mejora significativa de los umbrales VT1, VT2 y Dmax con una mejora de 10W, 10W y 7W respectivamente, sin llegar a mejorar el VO2máx. Considerando los valores analizados, al realizar las evaluaciones pre-post se proporciona información valiosa para atletas, entrenadores y científicos del deporteÍtem Comparison of three internationally certified firefighter protective ensembles: physiological responses, mobility, and comfort(Elsevier B.V., 2021-11) Quinn, Tyler D.; Gutiérrez Santamaría, Borja; Sáez Gómez de Cadiñanos, Iker; Santisteban Leguina, Aitor; Lee, Joo-Young; Kim, Jung-Hyum; Coca Núñez, AitorBackground: Fire protective ensembles (FPEs) are essential to safely perform firefighting job tasks; however, they are often burdensome to the workers. The aim of this study was to compare three internationally certified fire protective ensembles from the European Union (EU), South Korea (SK), and United States (US) on physiological responses, mobility, and comfort. Methods: Ten male professional firefighters performed a battery of exercises in the laboratory following the ASTM F3031-17 standard to evaluate mobility, occupation-specific performance, and physiological responses (body weight, heart rate (HR), core temperature (Tc), breathing rate (BR), and rating of perceived exertion (RPE)) to 20 min of treadmill walking (3.2 mph, 5% incline). All participants carried out the evaluation wearing each FPE in a random order. Mixed effects models examined time (pre-vs. post-) by ensemble (EU, SK, US) interactions for all physiological variables and compared comfort, performance, and subjective variables across ensembles. Results: No interaction effects were observed for body weight, HR, Tc, BR, or RPE (p = 0.890, p = 0.994, p = 0.897, p = 0.435, and p = 0.221; respectively). SK had greater trunk flexion than EU (78.4° vs. 74.6°, p = 0.026) and US had lower standing reach than EU (105.5 cm vs. 115.4 cm, p = 0.004). Agility circuit time was lower in US (9.3 s) compared to EU (9.8 s) or SK (9.9 s) (p = 0.051 and p = 0.019, respectively). Conclusions: The findings suggest that physiological burden remained largely unchanged across the international FPEs. However, mobility, performance, and comfort may be significantly influenced across types. International stakeholders and end users should consider design implications when choosing fire protective ensembles.Ítem Differences in Functional Capacity between Oncologic and Non-Oncologic Populations: Reference Values(Multidisciplinary Digital Publishing Institute (MDPI), 2024-01-25) Mojas Ereño, Egoitz; Santisteban Leguina, Aitor; Muñoz Pérez, Iker; Larrinaga Undabarrena, Arkaitz; Arietaleanizbeaskoa, María Soledad; Mendizabal Gallastegui, Nere; Grandes, Gonzalo; Cacicedo, Jon; Río de Frutos, XabierThis study is focused on the fact that in the context of increasing global aging and cancer diagnoses, additional challenges arise in clinical care. Adequate functionality and body composition are key to coping with antineoplastic treatment, which can lead to better treatment tolerance, survival, and quality of life. This is a cross-sectional comparative study focused on the assessment and comparison of body composition and functionality between cancer patients and a reference population, with the aim of establishing meaningful baseline values. Techniques such as manual dynamometry, the Five-Times Sit-to-Stand test, and bioimpedance were used to collect data from 374 oncologic patients and 1244 reference individuals. The results reveal significant disparities in functionality and body composition among participants, and provide age group-specific adjusted baseline values for those diagnosed with cancer. These findings may have crucial clinical implications for applying particular cut-off points designed for this population group, which makes the assessment process faster and more accurate, enhances the capacity of medical personnel to act quickly, and improves the management of frailty in cancer patients.Ítem Effects of 12 weeks of short-duration isometric strength training in university students(Asociación Española de Ciencias del Deporte, 2024-06-30) Santisteban Leguina, Aitor; Mojas Ereño, Egoitz; Virto, Naiara; Fernández, Juan Ramón; Gómez, Roberto; Río de Frutos, XabierPurpose: Isometric strength training has the advantage of improving musculoskeletal properties, neuromuscular function and health biomarkers compared with dynamic strength training. This study aimed to analyze the effects of short-term isometric strength training on pain, body composition, and biomarkers of health in young adults. Methods: This was a pre-post experimental study with isometric training period. The training period was carried out for 12 weeks with a single session per week, with a weekly training volume of 6 minutes. The study sample consisted of 22 students (20.5 years ± 1.37) of both sexes (15 males and 7 females). The maximum isometric force test (in Newton meters) using the MedX lumbar extension and knee extension machines. The InBody 770 were used for body composition analysis, visual analog scale for pain and glycated hemoglobin values were measured using the Quo-Lab. Results: Analysis of changes in pain showed a significant improvement in hip pain in the entire group (p≤0.05), with no other significant changes observed in the other pain scales (0.05), phase angle (0.02), glycated haemoglobin (0.00) and lumbar strength (<0.05) measured or segregating the sample by sex. Conclusion: The study demonstrates that a short duration strength training intervention can help to improve pain at anatomical points, reduce HbA1c levels, finding trends for improvement in numerous body composition variables. Highlighting the significant change in phase angle, a variable with a promising approach in the more accurate and comprehensive study of both body composition and metabolic health.Ítem Influence of technical skill level and sport specialization on surfing injuries: a cross-sectional study(Churchill Livingstone, 2024-10) Santisteban Leguina, Aitor; Muñoz Pérez, Iker; Río de Frutos, Xabier; Sáez Gómez de Cadiñanos, IkerObjective: This study aimed to analyze the influence of sport specialization and the level of technical skills on injury risk in male surfers. Design: Descriptive epidemiological study. Setting: Web-based surveys. Participants: 295 male surfers participated in the present study, of whom 25 (8.47%) were competitive surfers, and 270 (91.53%) were recreational surfers. Main outcome measure: This study consisted of a single registry. A web-based survey was used to record information on the injuries sustained during the past year. Results: No association was detected between the surfer's performance level and having suffered an injury during the practice (p > 0.05). Conversely, the results indicated that the higher the level of specialization, the greater the likelihood of suffering a sports-related injury (χ2 (3) = 12.9 p = 0.005; ES = 0.20). In addition, surfers who showed a medium-high self-concept of their skills (scores of 6, 7, and 8) tend not to get fewer injuries (χ2 (8) = 36.8 p < 0.001; ES = 0.35. Conclusion: higher-level specialization surfers tend to suffer more injuries than lower-specialization surfers. Nevertheless, a good self-concept of technical skills may contribute to a lower likelihood of injury.Ítem Predictive performance models in marathon based on half-marathon, age group and pacing behavior(Springer-Verlag Italia s.r.l., 2024-09) Muñoz Pérez, Iker; Castañeda Babarro, Arkaitz; Santisteban Leguina, Aitor; Varela-Sanz, AdriánObjective: The main aim of this study was to develop an equation for predicting performance in 42.2 km (MRT) using pacing and packing behavior, age group and previous 21.1 km time as possible explanatory variables. Methods: 1571 men and 251 female runners who took part in the Valencia Marathon and Half-Marathon were selected to display the regression models. Stepwise regression analysis showed as explanatory variables for MRT: pacing behavior, age group, and time in 21.1 km. Results: The analysis showed four regression models to estimate accurately MRT based principally on athletes previous performance in half-marathon and pacing behavior for men (R2= 0.72–0.88; RMSE= 4:03–8:31 [min:s]). For women, it was suggested a multiple linear regression for estimating MRT (R2 0.95; RSE= 8:06 [min:s]) based on previous performance in half-marathon and pacing behavior. The subsequent concordance analysis showed no significant differences between four of the total regressions with real time in the marathon (p>0.05). Conclusion: The present results suggest that even and negative pacing behavior and a better time in 21.1 km, in the previous weeks of the marathon, might accurately predict the MRT. At the same time, nomadic packing behavior was the one that reported the best performance. On the other hand, although the age group variable might partially explain the final performance, it should be included with caution in the final model because of differences in sample distribution, causing an overestimation or underestimation of the final time.Ítem Valores de referencia de la velocidad de la marcha en mayores de 65 años(Federación Española de Asociaciones de Docentes de Educación Física (FEADEF), 2022) Río de Frutos, Xabier; Sánchez Isla, José Ramón; Santisteban Leguina, Aitor; León Guereño, Patxi; Sáez Gómez de Cadiñanos, Iker; Coca Núñez, AitorObjetivo: Proporcionar valores de referencia de la Velocidad de la Marcha (VM) de cuatro metros en personas mayores de 65 años en el País Vasco y establecer puntos de corte para una detección temprana de la fragilidad en la práctica clínica. Diseño: Este es un estudio descriptivo de corte transversal, en el que se recogen valores de la prueba de VM de cuatro metros a 1,871 personas adultas mayores de 65 años, para luego extraer el tiempo de la prueba (TP) y la VM en metros por segundo. Resultados: Los puntos de corte variaron de 2,99 segundos a 3,95 segundos en TP y de 0,89 a 0,70 en VM en mujeres y de 2,66 segundos a 3,85 segundos en TP y de 0,99 a 0,73 en VM en los hombres. Los resultados de ANOVA, muestran que existe diferencia estadísticamente significativa en TP para grupos de edad (F =41,51 - p<,01) y sexo (F = 15,55 – p<,01) y en VM para edad (F =39,32 - p<,01) y sexo (F = 25,67 - p<,01). La disminución en las dos variables, resaltan que el parámetro del TP aumenta con el paso de los años un 32,97% y el valor de VM disminuye un 21,42% respectivamente, valores clínicamente relevantes. Conclusiones: Los datos muestran que los hombres consiguieron mejores puntuaciones en todos los rangos de edad respecto a las mujeres en la prueba de VM de 4 metros. La prueba de VM de cuatro metros es sencilla y aplicable en atención primaria para la detección temprana de fragilidad.
