The multimedia application technology has many applications in the teaching field, but no research has been found on the use of this technology to the construction of the sports health education of cloud-based platform. The healthy teaching of physical education (PE) should not only rely on teachers’ teaching, but also let students learn to learn independently. The multimedia modeling algorithm in the health cloud biometric authentication and data management system are of great importance in students’ PE learning. It is an attempt to build a sports health education cloud platform using multimedia application technology. In order to make up for the shortcomings of this research direction, this paper starts from the multimedia transmission algorithm, analyzes the relationship between multimedia computing technology and PE, and applies this technology to the construction of the sports health education cloud platform. It then analyzes the teaching effect of the constructed sports health education of cloud-based platform and draws a conclusion. In the study of students’ attitude towards the education of cloud-based platform, it was found that the sports health education of cloud-based platform can meet their needs, and students were also willing to accept it. In the survey of students’ learning needs for the education of cloud-based platform, it was found that the use of the sports health education of cloud-based platform can better meet their sports learning needs and improve learning interest and motivation. In the survey of students’ demand for the functions of the education of cloud-based platform, it was found that the use of the sports health education platform has changed students’ demand for the functions of the education of cloud-based platform. In the survey of how the education of cloud-based platform meets the needs of students, it was found that most people believed that the use of the education of cloud-based platform can meet the needs, and only 5% of students believed that the education of cloud-based platform did not meet their needs. In the investigation of the influence of the education of cloud-based platform on students’ ability, it was concluded that students’ learning ability has been greatly improved after using the sports health education platform. Multimedia modeling has a good role in promoting students’ sports health learning, which can improve students’ learning ability, and can also promote the construction of sports health education of cloud-based platform to become perfect.
