Level of evidence II Therapeutic studies - investigation of treatment results.īreath-hold diving (freediving) is an underwater sport that is associated with elevated hydrostatic pressure, which has a compressive effect on the lungs that can lead to the development of pulmonary edema. Conclusions: The diving team's training shows that scientific and systematic training is an important guarantee for high-level student-athletes training in ordinary universities in my country. Results: The in-depth research on diving training focuses on: (1) the detection and evaluation of diving technique training (2) the training of divers’ specific strength qualities (3) the monitoring of nutrition and weight of female athletes (4) Pre-match psychological training for outstanding diving athletes. Methods: The scientific research support system used in the thesis includes: physiological and biochemical monitoring, health and sports injury monitoring, nutrition and weight monitoring, psychological consultation and monitoring, technical training support system, training quality management system, physical training support system, and athlete training database. Objective: This article intends to take the diving team as an example to explain the role and significance of scientific training in developing competitive sports in my country's ordinary colleges and universities and put forward suggestions for the establishment, organization, and implementation of scientific training.

It can make full use of universities’ multidisciplinary and high-tech advantages, increase the technological content of competitive training, and accelerate the improvement of sports level. It helps to improve the cultural quality of Chinese athletes and cultivate new sports talents for comprehensive development. Introduction: The organization of high-level sports teams in colleges and universities is an important measure for my country's competitive sports to break the traditional monopoly and monopoly pattern and go to the market and society in an all-around way. This article provides an overview of clinical manifestations of DCI following repetitive BH dives and discusses possible mechanisms based on clinical and neuroimaging studies. DCI prevention strategy includes avoiding long-lasting repetitive dives for more than several hours, prolonging the surface intervals. The first aid normobaric oxygen appears beneficial. We consider that the most plausible mechanisms are arterialized venous gas bubbles passing through the lungs, bubbles mixed with thrombi occlude cerebral arteries and then expand from N 2 influx from the occluded arteries and the brain. The underlying mechanisms remain to be elucidated. These lesions localized in the external watershed areas and deep perforating arteries are compatible with cerebral arterial gas embolism.
Neuroradiological studies on Ama divers showed symptomatic and asymptomatic ischemic lesions in the cerebral cortex, subcortex, basal ganglia, brainstem, and cerebellum. It manifests mainly with cerebral involvements, especially stroke-like brain attacks with the spinal cord spared. “Taravana,” the diving syndrome described in Polynesian pearl divers by Cross in the 1960s, is likely DCI.
Hence, BH diving can theoretically cause decompression illness (DCI). Post-dive venous gas emboli have been documented in commercial BH divers (Ama) after repetitive dives with short surface intervals. Nitrogen (N 2 ) accumulation in the blood and tissues can occur due to breath-hold (BH) diving.
