Production of free radicals and oxidative damage during physical activity is a topic that is intensively studied and paid a lot of attention, first of all in professional sports. Marathon is ...categorized as extremely demanding sports discipline, as it induces high energy consumption and also requires special mental self-control. We presented cases of two athletes of different age, who have been on dissimilar level of sports readiness, and also had various approach to physical activity and exercise. During 10 days they ran out 10 marathons, partly on a flat terrain, and partly on hilly, which produced different level of effort in conquering the terrain. Also, both athletes had complex supplementation scheme in order to prevent electrolyte imbalance and excessive production of free radicals. Blood samples were taken in the morning and immediately after the end of the marathon. Measured oxidative stress biomarkers changed without a noticeable pattern, but these changes did not vary greatly among themselves. Catalase activity in both marathon runners was higher after marathon almost after every race for 10 days. On the other hand, amount of reduced glutathione was lower after marathon in both athletes in the same manner. Based on the obtained results we can conclude that adequate supplementation could have crucial role in prevention of oxidative damage.

Bulgular: Çalışma sonucunda, Nike firmasının yürüttüğü pazarlama çabalarının hedef kitlelere yönelik duyusal, duygusal, düşünsel, davranışsal ve ilişkisel deneyim alanları yaratmakta olduğu hususu değerlendirilmiştir.
How did the city-state of Athens defeat the invaders from Persia, the first world empire, on the plain of Marathon in 490 BCE? Clever scholars skeptical of our earliest surviving source, Herodotus, ...have produced one ingenious theory after another. In this stimulating new book, bound to provoke controversy, Peter Krentz argues that Herodotus was right after all.
Beginning his analysis with the Athenians' first formal contact with the Persians in 507 BCE, Krentz weaves together ancient evidence with travelers' descriptions, archaeological discoveries, geological surveys, and the experiences of modern reenactors and soldiers to tell his story.
Krentz argues that before Marathon the Athenian army fought in a much less organized way than the standard view of the hoplite phalanx suggests: as an irregularly armed mob rather than a disciplined formation of identically equipped infantry. At Marathon the Athenians equipped all their fighters, including archers and horsemen, as hoplites for the first time. Because their equipment weighed only half as much as is usually thought, the Athenians and their Plataean allies could charge almost a mile at a run, as Herodotus says they did. Krentz improves on this account in Herodotus by showingwhythe Athenians wanted to do such a risky thing.
Se recomienda empezar a entrenar de forma ligera e ir aumentando la intensidad progresivamente. También es conveniente realizar chequeos médicos, electrocardiogramas y revisiones coronarias. Conocer ...la propia frecuencia cardíaca es importante. El test de lactato indica cuál es la velocidad máxima a la que se debe correr para evitar la fatiga muscular.
It is recommended to start training lightly and increase the intensity progressively. Medical checks, electrocardiograms and coronary examinations are also appropriate. Knowing one's own heart rate is important. The lactate test indicates the maximum speed to be run to avoid muscle fatigue.
