description The aim of the present study was to examine the physiological and training characteristics in marathon runners with different sport experiences (defined as the number of finishes in marathon races). The anthropometry and physiological characteristics of men recreational endurance runners with three or less finishes in marathon races (novice group, NOV; n = 69, age 43.5 ± 8.0 years) and four or more finishes (experienced group, EXP; n = 66, 45.2 ± 9.4 years) were compared. EXP had faster personal best marathon time (3:44 ± 0:36 vs. 4:20 ± 0:44 h:min, p < 0.001, respectively); lower flexibility (15.9 ± 9.3 vs. 19.3 ± 15.9 cm, p = 0.022), abdominal (20.6 ± 7.9 vs. 23.8 ± 9.0 mm, p = 0.030) and iliac crest skinfold thickness (16.7 ± 6.7 vs. 19.9 ± 7.9 mm, p = 0.013), and body fat assessed by bioimpedance analysis (13.0 ± 4.4 vs. 14.6 ± 4.7%, p = 0.047); more weekly training days (4.6 ± 1.4 vs. 4.1 ± 1.0 days, p = 0.038); and longer weekly running distance (58.8 ± 24.0 vs. 47.2 ± 16.1 km, p = 0.001) than NOV. The findings indicated that long-term marathon training might induce adaptations in endurance performance, body composition, and flexibility.

The findings indicated that long-term marathon training might induce adaptations in endurance performance, body composition, and flexibility.El objetivo del presente estudio fue examinar las características fisiológicas y de entrenamiento en corredores de maratón con diferentes experiencias deportivas (definidas como el número de finales en carreras de maratón). Las características antropométricas y fisiológicas de los corredores de resistencia recreativos masculinos con tres o menos finales en carreras de maratón (grupo novato, NOV; n = 69, edad 43,5 ± 8,0 años) y cuatro o más finales (grupo experimentado, EXP; n = 66, 45,2 ± 9,4 años) se compararon. EXP tuvo un tiempo de mejor maratón personal más rápido (3:44 ± 0:36 frente a 4:20 ± 0:44 h: min, p <0,001, respectivamente); menor flexibilidad (15,9 ± 9,3 frente a 19,3 ± 15,9 cm, p = 0,022), abdominal (20,6 ± 7,9 frente a 23,8 ± 9,0 mm, p = 0,030) y grosor del pliegue cutáneo de la cresta ilíaca (16,7 ± 6,7 frente a 19,9 ± 7,9 mm, p = 0,013) y la grasa corporal evaluada mediante análisis de bioimpedancia (13,0 ± 4,4 frente a 14,6 ± 4,7%, p = 0,047); más días de entrenamiento semanales (4.6 ± 1.4 vs 4.1 ± 1.0 días, p = 0.038); y mayor distancia de carrera semanal (58,8 ± 24,0 frente a 47,2 ± 16,1 km, p = 0,001) que NOV. Los hallazgos indicaron que el entrenamiento de maratones a largo plazo podría inducir adaptaciones en el rendimiento de resistencia, la composición corporal y la flexibilidad.Nikolaidis, Pantelis-will be generated-orcid-0000-0001-8030-7122-600Clemente-Suárez, Vicente Javier-will be generated-orcid-0000-0002-2397-2801-600Chlíbková, DanielaKnechtle, Beatapplication/pdfengFrontiers in PhysiologyCC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Body fatEndurance trainingMaximal oxygen uptakeSkinfold thicknessSport historyTraining volumeGrasa corporalEntrenamiento de resistenciaConsumo máximo de oxígenoPliegue cutáneoHistorial deportivoEntrenamiento volumenTraining, anthropometric, and physiological characteristics in men recreational marathon runners: The role of sport experienceEntrenamiento, características antropométricas y fisiológicas en hombres corredores de maratón recreativo: el papel de la experiencia deportivaArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/acceptedVersionhttps://www.frontiersin.org/articles/10.3389/fphys.2021.666201/fullAragon-Vargas, L.
