This study examined changes in the sex differences in performance across time in female and male master runners competing in a mountain marathon compared to a flat city marathon. Methods: The association between age and perform…

Effect of marathon characteristics and runners' time category on pacing profile.

2020

This study aimed to analyse differences in pacing profiles in four marathon competitions and to explore that pacing per time category. A database of 91,493 runners gathered from 4 different races was analysed (Valencia, Chicago, London and Tokyo Marathon). Participants were categorized in accordance with their completion time. The relative speed of each section for each runner was calculated as a percentage of the average speed for the entire race. In the four marathons studied, the first 5 km differed widely, presenting London the highest relative speeds (5 km: CI95% London vs. Valencia [12.1, 13.6%],

Antiplatelet Therapy in Marathon Runners: More Harm than Benefits?

2013

We read with interest the article by Arthur J. Siegel, who recently concluded that prophylactic aspirin for primary prevention of cardiac events in marathon runners may be a viable approach for lowering the global risk of cardiovascular events in these subjects. Although there is a credible hysiological basis for supporting this provocative suggesion, and the use of nonsteroidal anti-inflammatory drugs is requent in athletes, there are, however, some issues that hould be considered, and which would globally overwhelm he hypothetical advantages of antiplatelet therapy in this eculiar setting. First, there is no controlled, randomized study that has efinitely proven the existence of any poten…

Inter-individual different responses to continuous and interval training in recreational middle-aged women runners

2020

A crucial subject in sports is identifying the inter-individual variation in response to training, which would allow creating individualized pre-training schedules, improving runner’s performance. We aimed to analyze heterogeneity in individual responses to two half-marathon training programs differing in running volume and intensity in middle-aged recreational women. 20 women (40 ± 7 years, 61 ± 7 kg, 167 ± 6 cm, and VO2max = 48 ± 6 mL⋅kg–1⋅min–1) underwent either moderate-intensity continuous (MICT) or high-intensity interval (HIIT) 12-week training. They were evaluated before and after training with maximal incremental tests in the laboratory (VO2max) and in the field (time to exhaustion…

Stress and recovery states after a 24 h ultra-marathon race: A one-month follow-up study

2011

Abstract Objectives The purpose of this study was to investigate the athlete’s perception of stress and recovery states following a 24 h ultra-marathon race. Design and method Psychological states were assessed in 14 male subjects before as well as 1, 3, 6, 9, 12, 15, 21, and 30 days after the race. Results The results suggest an ultra-endurance race induces perceived stress and leads to subsequent alterations in perceived recovery, whatever the psychological, physical, emotional or social dimensions according to a unique time-course for the several components evaluating the stress and recovery process. Stress and recovery levels related to the 24 h race showed that a period of 2 weeks is r…

Recovery of Inflammation, Cardiac, and Muscle Damage Biomarkers After Running a Marathon

2019

Bernat-Adell, MD, Collado-Boira, EJ, Moles-Julio, P, Panizo-González, N, Martínez-Navarro, I, Hernando-Fuster, B, and Hernando-Domingo, C. Recovery of inflammation, cardiac and muscle damage biomarkers after running a marathon. J Strength Cond Res 35(3): 626-632, 2021-Physical endurance sports conditions the increase of blood biomarkers responsible for the acute inflammatory response. The purpose of this study was to observe the impact of intense physical exercise on these biomarkers and detect their recovery pattern. This is an experimental study of repeated measures (pre-post marathon). The biomarkers lactate dehydrogenase (LDH), creatine kinase (CK), high-sensitivity troponin T (hs-TNT),…

Muscle cramping in the marathon: dehydration and electrolyte depletion vs. muscle damage

2020

Martinez-Navarro, I, Montoya-Vieco, A, Collado, E, Hernando, B, Panizo, N, and Hernando, C. Muscle Cramping in the marathon: Dehydration and electrolyte depletion vs. muscle damage. J Strength Cond Res XX(X): 000-000, 2020-Our aim was to compare dehydration variables, serum electrolytes, and muscle damage serum markers between runners who suffered exercise-associated muscle cramps (EAMC) and runners who did not suffer EAMC in a road marathon. We were also interested in analyzing race pacing and training background. Nighty-eight marathoners took part in the study. Subjects were subjected to a cardiopulmonary exercise test. Before and after the race, blood and urine samples were collected and…

On the correlation of psychological characteristics within recreational marathon runners

2015

Oschwald Miles, 2015. On the Correlation of Psychological Characteristics Within Recreational Marathon Runners. Master’s Thesis in Sport and Exercise Psychology. Department of Sport Science. University of Jyväskylä. University of Jyväskylä. 40 p. The purpose of this research study was to explore the performance related experiences of recreational marathon runners. Specifically, the relationship these experiences have with other psychological constructs involved in undertaking and maintaining participation in a given sport. Using self-report measures the psychobiosocial states prior to most successful performances, achievement goal orientations, motivation and regulation for sport participat…
