Background. Running causes that people become more and more willing to engage in physical activity. It is an valid exercise that significantly decreases postprandial glycemia. The higher the training load, the more important it is to complement nutrients necessary for organism regeneration. Modern food industry provides many products that can help in resynthesis of muscle glycogen. The study presents a mutual correlation between consuming high-carbohydrate products with and without having exercise afterwards and the shape of the blood glucose curve. Material and methods. Nine healthy and hard training male adult athletes participated in 2-part (P1 and P2) research: P1 with, and P2 without run. After the run, the athletes had a specified meal, after which capillary blood glucose test was taken for P1 before the run and for both groups 2-3 min, at 30, 60, 90 and 120 min after the meal. Results. The comparison of the area under the curve (AUC ) at rest and after 1 hr run showed statistically significant variations after every 30 minutes period and in the overall AUC . The smallest AUC occurred after consuming chips and spinach pasta and the highest after potatoes, white and brown rice. Conclusions. Physical activity does not change the way glucose is released into the blood, but it lowers postprandial glycemia, especially after 30-90 minutes after training completion. This study indicates that consuming potatoes and rice leads to the highest rate of muscle glucose uptake and further faster glycogen re-synthesis after the run. Accordingly, these products can be a good choice for athletes having a short break between training bouts.
In the current time of human inactivity running becomes an ideal compensatory means, which acts as prevention against civilization diseases that are is some way affected by the lack of physi-cal activity. In addition to the beneficial physical effect of running on the human body, we can ob-serve a positive impact on psychological indicators as well. Marathon race represents one of the most challenging athletic disciplines in the physiological and psychological terms. In a positive way, it af-fects cardiovascular, musculoskeletal systems and can act as a stress relieving mediator [5]. We may argue that the dominant motivation of the majority of the marathon runners is comple-tion of the race, for which participant must be systematically trained. Seeing that, marathon races become more and more popular every year and they grow both in quality and quantity [5].Every year, there are many marathons races organized in the world. Their participants are doing well and overcoming themselves. In our paper we analyze the two oldest marathon races in the world in particular, the Boston Marathon in the US and the International Peace Marathon in Kosice. As a method for examining individual events, we have select comparison and SWOT analysis. The history of Boston and Košice marathons creates an important marketing element, that is used to form valuable incentive for promoting the event. While the Boston marathon is considered the oldest marathon in the world, the Košice marathon is the oldest marathon on the European continent and the third oldest in the world. Our analysis shows that both marathons are in a favorable position. An offensive marketing strategy suggests the predominance of strengths over weaknesses and opportunities over threats. From the profile of the cultural point of view and the time of the year, the Kosice Mara-thon is more attractive and acceptable for some participants than the Boston marathon, where the runners experience much more difficult course. Nevertheless, based on strengths, both events are able to use their opportunities, which predisposes them to consolidate and improve their position in the everlasting competition of international marathons.
Background: The most common risk factors for running-related injuries are mistakes, such as insufficient warm-up and stretching exercises, during training. Good preparation and proper training reduces the risk of sport-related injuries. Aim of the study: To examine fundamental movement patterns and likelihood of injury in amateur runners. Material and methods: Twenty-four amateur long-distance runners from Opole region (Poland) were divided into two groups. The first group comprised 12 runners from the club “Kotwica Brzeg”, who did a proper warmup before training and stretching exercises after training. The second group comprised 12 runners from other clubs who did not undertake any warm-up or stretching exercises (control group). Fundamental movement patterns were tested by the Functional Movement Screen test (FMS). Results: The mean FMS test score was higher in “Kotwica Brzeg” runners (17.08 points) than in the control group (15.50 points), but this was not statistically significant. The “Kotwica Brzeg” runners performed better in five of the FMS tests, but this was only significant for the rotational stability test. Conclusions: Runners who did a proper warm-up and stretching exercises achieved better results in the FMS test, which may reduce the risk of running-related injuries.
Introduction. The marathon is an increasingly popular form of athletic competition, especially among amateur runners. It seems, therefore, important to determine how this type of exercise affects the runner’s body. Aim of Study. The aim of the study was to identify hematological and biochemical changes in the blood of amateur runners after a marathon run. Material and Methods. The study involved 10 male runners aged from 28 to 42 years. Their blood was collected from the fingertip four times: a day before the competition and one, three and five days after the race, and subjected to hematological and biochemical analysis. Results. The results revealed a statistically significant increase in the number of leukocytes, including monocytes and granulocytes, creatine kinase (CK) and lactate dehydrogenase (LDH) activity, urea concentration, and ferric reducing ability of plasma (FRAP). On the other hand, the values of certain indices, such as the number of erythrocytes, hemoglobin concentration, hematocrit, and red blood cell distribution width, decreased. There were no statistically significant changes in the number of lymphocytes and thrombocytes, the concentration of total protein, albumin, and polyphenols. Conclusions. Prolonged and intense physical eexercise, such as a marathon run, causes multiple significant changes in the body. These changes can lead to health disorders and deterioration of physical fitness.
