Introduction

Weightlifting is a sport with a long history. It involves grasping the barbell with both hands and performing reasonable technical movements. The maximum strength of the body is used to lift the barbell above the head. The weight of the lifted barbell is the basis for winning or losing. Weightlifting may seem simple, but it is a comprehensive test of the athlete’s muscle strength, explosive power, and coordination (Huebner et al., 2020). From feet to legs, from hips to the abdomen, from shoulders to arms, the entire body must be traction with a complete power chain. Complete the snatch and clean and jerk. Unlike most people’s impressions, weightlifting is not a sport that only requires “brute force”. Weightlifting requires excellent technical movements, but in extreme weights, it is not easy to control technical movements (Golshani et al., 2018). When the athlete lifts, he needs to mobilize all the muscles of his body and hold his breath. The pressure in the body increases instantly (Yasser et al. 2019). If the technical movements are not controlled well, the waist, wrist, elbow, and shoulder are all easily injured (Soriano et al. 2019).

For the Tokyo Olympics, the International Weightlifting Federation changed the competition level (Pichardo et al. 2019). The Chinese weightlifting team responded actively, adhering to keeping pace with the times and constantly innovating. Not only did it not regress, but on the contrary demonstrated a stronger dominance. The Chinese weightlifting team won 7 gold medals and 1 silver medal in the Tokyo Olympics. I won a gold medal with a total score of 364 kg. The result broke the previous world record that I had maintained (Figure 1).

During the Tokyo Olympic period, the Chinese weightlifting team continuously researches the most advanced weightlifting training methods in the world and combines the physical fitness and strength characteristics to form a complete set of scientific weightlifting training methods for China (Solberg et al. 2019). The team makes full use of technology to help train with the wings of technology. The Chinese weightlifting team also pays attention to building a composite support team to do a good job in guaranteeing athletes’ training, rehabilitation, scientific research, and medical care (Huebner & Perperoglou 2019). The Chinese weightlifting team adheres to the concept of individual project team combat. From training to competition, from scientific research to medical affairs, from nutrition to recovery, it has organized several coaches (physical fitness, rehabilitation, and technology) and multidisciplinary researchers (biomechanics, physiology, psychology, and nutrition) combined teamwork (Figure 2) (Yasser et al. 2019).

The National Weightlifting Team Training Hall of China has a scientific research monitoring laboratory and a body recovery laboratory. The scientific research monitoring laboratory is divided into a physical therapy area, a training monitoring area, a rehabilitation area, and a psychological training area (Liu et al. 2018). Biochemical analyzers, automatic electrolyte analyzers, etc. monitor the intensity and effect of athletes’ training, which can intuitively detect the athlete’s body’s response to training intensity and training volume; biochemical indicator testing equipment such as hemoglobin testers can accurately reflect athletes’ adaptation of training and the recovery of the body can help coaches develop training plans more scientifically, and help athletes reduce the hidden dangers of injuries (Golshani et al. 2018; Sun et al., 2018). The compression cold therapy equipment in the body recovery laboratory has 9 treatment bags, which are placed on different parts of the body, which can produce a large area of ice-like effect and help athletes speed up circulation. Compression training equipment is tied to the upper limbs or lower limbs near the heart position, with 30% to 40% of the maximum strength training, you can achieve 100% of the maximum strength training effect, to a certain extent, can prevent athletes from sports injuries (Liu et al. 2011).

In terms of sports equipment, the weightlifting shoes developed by Anta for me and my teammates are made of wear-resistant fiber, with a wear resistance of 2.5 times that of ordinary materials, and can withstand the weight of more than 14 adults. This weightlifting shoe has the characteristics of arch shock absorption, which can absorb the impact of the heel and reduce the athlete’s risk of injury (Legg et al. 2017). In addition, the weightlifting competition clothes provided by Anta also apply a unique lumbar support system, which can reduce muscle damage caused by being overweight and demonstrate the power of technology.

Athletes’ success is inseparable from the team’s efforts. In terms of scientific and technological assistance, the Chinese national weightlifting team has formed several major systems, including nutrition, rehabilitation, physical fitness, technical analysis, psychological and physiological and biochemical monitoring, including logistics support personnel, scientific and technical personnel, and they are always preparing for the athletes. Provide a full range of help, while rapidly improving the athlete’s competitive level, but also pay more attention to the health of the athletes.
