Liang jing marathon runner8/12/2023 High temperature impacts the performance of marathon athletes, and hypothermia harms athletes 11, 12. Obtaining the maximum energy supply of the human body also helps assess the combat effectiveness of a soldier 5 and ordinary people to participate in war.įor many years, sports researchers around the world have been conducting similar studies, including pre-competition hypothermia, post-competition hypothermia, and pre-competition and post-competition warming studies 6 at the cold Winter Olympics, as well as various Oxygen inhalation, high-intensity training at high altitudes 7, 8, 9, 10, etc., these studies have achieved positive results. These people lack military training and actual combat experience and have limited combat power to participate in the war. The war between Russia and Ukraine is going on, and now ordinary Ukrainian residents are also participating in the war. The relationship between human energy expenditure and the external environment needs to be studied to assess the individual strength of marathon runners. Physical performance is also affected by the surrounding environment, including temperature, humidity, road slope, road friction, and so on 3, 4. The performance of athletes is closely related to physical fitness 2. Marathon runs for a long time and consumes much energy. Physical fitness is the premise to maintain and complete the human body’s essential life activities and physical skills. Sports is an activity developed to meet the needs of human production, military, and health 1. This paper’s theories and methods can effectively help design the marathon route and determine the race time. Dangerous risk zones for wind speed and temperature on dangerous path sections are also formulated for athletes to make their assessments. 315 cal/min/kg, should be taken as the maximum energy supply for Chinese male marathon runners. We suggest that the physical energy consumption ratio of 90%, i.e. The method of quantifying the slope and temperature and calculating the percentage of athletes’ physical consumption proposed in this paper can evaluate the route design of field marathons. The study shows that the large slope and long-distance of CP2 to CP3 section and the low temperature during the competition are the main reasons for the accident. We analyze the human body’s route slope, travel speed, and heat dissipation under low temperatures in this marathon. The energy equations are combined with the maximum energy supply of Chinese male athletes to study this accident. Twenty-one runners died, and eight were injured in the China Baiyin marathon on May 22, 2021. High temperature impacts the performance of marathon athletes, and hypothermia harms athletes.
