Entering midsummer, the weather is getting hotter and the temperature continues to rise. As the saying goes, "Practice three or nine in winter and three or five in summer." The scorching summer is a favorable time for military officers and soldiers to strengthen their physical training and hone their willpower. Of course, during summer physical training, officers and soldiers must pay attention to controlling the training intensity and amount, and be cautious of heatstroke. Pay attention to the following details during summer physical training. Organize warm-up activities carefully. Before starting physical training, it is important to warm up and not cut corners during the warm-up process due to the hot weather. Preparation activities aimed at increasing body temperature and heart rate, increasing joint and muscle flexibility, and accelerating nerve and muscle response speed can effectively prevent sports injuries. It should be noted that the human body consumes a lot of energy in summer. If the amount of warm-up exercise is too large, it can cause fatigue in the body and prevent it from being in a good state during formal training. Reasonably choose the time for physical training. Although the weather is cool in the morning, the inversion layer near the ground makes it difficult for air pollutants to spread. Therefore, it is not advisable for military personnel stationed in urban areas to undergo high-intensity physical training in the morning to avoid inhaling harmful substances and inducing diseases such as the throat and trachea. Evening is a suitable time for high-intensity physical training. In a hot and humid environment, physical training should start with low intensity and a short period of time, gradually increasing the amount, intensity, and duration of training. Scientific training to prevent heatstroke. The biggest problem caused by the reduced difference between body temperature and external environmental temperature in summer is that it hinders the body's heat dissipation. During training, the body produces 8-10 times more calories than when it is quiet, or even more. If these calories cannot be taken away in time, it can cause a significant increase in body temperature, which can be life-threatening in severe cases. In order to cope with this situation, the human body has evolved a series of adaptive mechanisms, such as evaporating heat through sweating, and using increased blood flow through the skin, capillary dilation, and other methods to dissipate heat. However, because the muscles are still working at this time, the heart has to accelerate to meet the needs of high-intensity training, leading to soaring heart rate, decreased training effectiveness, and subjective fatigue. Therefore, when training in a high-temperature environment, if symptoms such as headache, dizziness, thirst, excessive sweating, limb weakness and soreness, lack of concentration, and uncoordinated movements occur, it may be a manifestation of heatstroke. At this point, training should be stopped and transferred to a cool and ventilated place in a timely manner. Water and salt should be replenished, and recovery can be achieved in a short period of time. Properly arrange strength training. Persisting in summer physical training can indeed sharpen the fighting spirit of officers and soldiers. However, this does not mean that outdoor training can only be organized in summer. In fact, it is advisable to schedule strength training once or twice a week to improve muscle strength in a more comfortable indoor environment. On the one hand, strengthening strength training plays a very important role in enhancing the muscle's energy absorption and buffering ability, as well as preventing injuries and illnesses for officers and soldiers; On the other hand, it can significantly improve the experience of summer physical training for officers and soldiers, which helps to restore their physical fitness and adjust their training status. Only through hard training can we produce elite soldiers, and elite soldiers can win battles. Conducting physical training in summer not only helps to improve the body's metabolic function and circulatory system, but also strengthens cardiovascular function. It can also cultivate the temperature regulation ability of officers and soldiers, which helps to enhance the body's adaptability to high temperature and humidity environments. Of course, everything should be done within one's capabilities. During summer physical training, each officer and soldier should choose the appropriate training intensity based on their basic physical fitness, and should not blindly practice hard. (Lai Xin She)
