  • Influence of a Montmorency Cherry Juice Blend on Indices of Exercise
    Dimitriou et al. Journal of the International Society of Sports Nutrition (2015) 12:22 DOI 10.1186/s12970-015-0085-8 RESEARCH ARTICLE Open Access Influence of a montmorency cherry juice blend on indices of exercise-induced stress and upper respiratory tract symptoms following marathon running—a pilot investigation Lygeri Dimitriou1*, Jessica A Hill2, Ahmed Jehnali3, Joe Dunbar3, James Brouner4, Malachy P. McHugh5 and Glyn Howatson6,7 Abstract Background: Prolonged exercise, such as marathon running, has been associated with an increase in respiratory mucosal inflammation. The aim of this pilot study was to examine the effects of Montmorency cherry juice on markers of stress, immunity and inflammation following a Marathon. Methods: Twenty recreational Marathon runners consumed either cherry juice (CJ) or placebo (PL) before and after a Marathon race. Markers of mucosal immunity secretory immunoglobulin A (sIgA), immunoglobulin G (IgG), salivary cortisol, inflammation (CRP) and self-reported incidence and severity of upper respiratory tract symptoms (URTS) were measured before and following the race. Results: All variables except secretory IgA and IgG concentrations in saliva showed a significant time effect (P <0.01). Serum CRP showed a significant interaction and treatment effect (P < 0.01). The CRP increase at 24 and 48 h post-Marathon was lower (P < 0.01) in the CJ group compared to PL group. Mucosal immunity and salivary cortisol showed no interaction effect or treatment effect. The incidence and severity of URTS was significantly greater than baseline at 24hand48hfollowingtheraceinthePLgroupandwasalsogreaterthantheCJgroup(P < 0.05). No URTS were reported in the CJ group whereas 50 % of runners in the PL group reported URTS at 24 h and 48 h post-Marathon.

  • Ryan Hall Inspiring with the Gift
    Ryan Hall Inspiring With the Gift. by TIto MoraLES he men’s Olympic Marathon Trials come around only once every four years, Tand the stakes are always high. On the morning of November 3, 2007, 130 of the country’s best marathon- ers, including 25-year-old Ryan Hall, clustered in the predawn darkness near Rockefeller Center to vie for the right to represent the United States at the 2008 Olympic Games. While all had spent the better part of their lives training for this moment, only three would make the team. The atmosphere for these Trials was particularly electric. For the first time in history, the competition was being staged in conjunction with the New York City Marathon, one of the highest-profile races on the planet. The course, which featured five challenging loops through Central Park, had been designed for big- ger crowd support and heightened drama. Anything to do with the Big Apple, it seems, always equates to heightened drama. Aside from Hall, the field included all three returning marathoners from the 2004 Olympic team: Meb Keflezighi, who earned a silver medal in Athens; Alan Culpepper; and Dan Browne. Other headliners included Khalid Khannouchi, a former world record holder who has thrice broken 2:06 in his illustrious career; the Hansons-Brooks team, a 13-member contingent led by Brian Sell; Ryan Shay, the 2003 USATF marathon champion; and Abdi Abdirahman, whose marathon PR of 2:08:56 had earned him the third seed. But the two runners who seemed to be bringing the most buzz to the proceed- ings were upstarts Hall and Dathan Ritzenhein, 24—two of “the big three” from the celebrated high school class of 2001.

  • Performance and Thermal Perceptions of Runners Competing in the London Marathon: Impact of Environmental Conditions
    International Journal of Environmental Research and Public Health Article Performance and Thermal Perceptions of Runners Competing in the London Marathon: Impact of Environmental Conditions Tim Vernon * , Alan Ruddock and Maxine Gregory Sport and Physical Activity Research Centre, Department of Sport and Physical Activity, Sheffield Hallam University, Sheffield S10 2BP, UK; [email protected] (A.R.); [email protected] (M.G.) * Correspondence: [email protected]; Tel.: +44-(0)-114-225-5761 Abstract: The 2018 Virgin Money London Marathon (2018 VMLM) was the hottest in the race’s 37-year history. The aims of this research were to (1) survey novice mass participation marathoners to examine the perceptual thermal demands of this extreme weather event and (2) investigate the effect of the air temperature on finish times. A mixed-methods design involving the collection of survey data (n = 364; male = 63, female = 294) and secondary analysis of environmental and marathon performance (676,456 finishers) between 2001 and 2019 was used. The 2018 VMLM mean finishing time was slower than the mean of all other London marathons; there were positive correlations between maximum race day temperature and finish time for mass-start participants, and the difference in maximum race day temperature and mean maximum daily temperature for the 60 days before the London Marathon (p < 0.05). Of the surveyed participants, 23% classified their thermal sensation as ‘warm’, ‘hot’ or ‘very hot’ and 68% ‘thermally comfortable’ during training, compared with a peak of 95% feeling ‘warm’, ‘hot’ or ‘very hot’ and 77% ‘uncomfortable’ or ‘very uncomfortable’ during the 2018VMLM.
