Exercise, Telomeres, and Cancer: "The Exercise-Telomere Hypothesis".

Telomeres are genomic complex at the end of chromosomes that protects the DNA and telomere length (TL) is related to several age-related diseases, lifespan, and cancer. On the other hand, cancer is a multifactorial disease that is responsible for reduce the quality of life and kills millions of people every year. Both, shorter TL and cancer are related and could be treated or prevented depending of the lifestyle. In this review we discuss the possible role of exercise in the relationship between shorter telomeres, telomerase activity, and cancer. In summary, there is evidence that exercise leads to less telomere attrition and exercise also may diminish the risk of cancer, these two outcomes are possible intermediated by a reduction in oxidative stress, and chronic inflammation. Although, there is evidence that shorter TL are associated with cancer, the possible mechanisms that one may lead to the other remains to be clarified. We assume that humans under cancer treatment may suffer a great decrease in quality of life, which may increase sedentary behavior and lead to increased telomere attrition. And those humans with already shorter TL likely lived under a poor lifestyle and might have an increased risk to have cancer.

The first sport injuries in the history of medicine.

Medical science is as old as human history and the need for disease treatment. Archivists, researchers and historians are collaborating in the project to preserve the documentary inheritance and make the medical science useful to the public. This research aims to identify and analyze the first registered sport injuries in the history of medicine. After a review of the literature, the Homeric epics, the texts of the first historical period of ancient Greece, were identified and analyzed as the texts which contain the first sport injuries in world history.

The use of deep friction massage with olive oil as a means of prevention and treatment of sports injuries in ancient times.

The aim of this research was to analyse the use of olive oil as a means of prevention and treatment of sports injuries in the ancient world. The method adopted was based on a thorough study of Greek and world literature. Writings of major ancient philosophers and physicians such as Hippocrates, Aristotle, Philostratus, and Lucian have been analysed in depth. According to the results, the use of massage, together with olive oil rub, helped to reduce muscle fatigue, to remove lactic acid, and to prevent the occurrence of sports injuries through flexibility provided to the skin of athletes. The therapeutic use of oil in the ancient world was fully recognized; and as a result Athenian athlothetes (sponsors of sporting events) provided free oil to all sport facilities where athletes could make free use of it [1].
