Constraints faced when becoming a guide is to communicate technical training with tools, collaburation and excelation with athletes, and if there are health problems or injuries to the leg muscles it will not be possible to accompany athletes in training. All problems encountered step by step can be overcome, and all of them are done manually so it takes a long time. But the problems that occur remain an obstacle so that they are less than optimal when doing exercises (kolaburasi, accelerations, communication during training in the form of movement and sound codes). The purpose of this research is to find out and get information about "making the development of training aids (remote control and headsets) for blind sprint athletes as direction controllers when running sports training programs. The validation presentation of the questionnaire that was distributed to the sample shows that 94%-96% of them admit that the training aids (remote control and control) meet the criteria. Collaboration of motion acceleration, communication is one of the problems that often accurs, with the remote communication control has been standardized so that athletes can easily remember and respond to existing information making it easier for athletes to make decisions. This technology will act as a companion eye that can give a warning if an error occurs in the safe position of the visually impaired. At first the position of the blind athlete's hand. With the use of remote control the athlete is free to do exercises and techniques that have been mastered without worrying about the runners (guide).

The purpose of this study was to develop training aids (remote control and headset) for sprint athletes with visual impairments as a directional controller during a sprint running exercise program. The benefit of this research is to produce training aids for sprint athletes with visual impairments. This study uses research and development research and development methods. The research was carried out in 2 places, namely the Yapentra SLB-A school for small-scale trials and Karya Murni's SLB-A large-scale trials for the development of blind sprint athletes in North Sumatra NPC. The analysis technique uses quantitative descriptive. The conclusions of this study are: (1) In using remote control and headsets, athletes focus more on personal abilities without thinking about collaboration, acceleration and communication, (2) Using remote control and headsets, athletes are more confident and more independent in sprinting activities. Using remote control and headsets, guades and coaches are more focused in conveying information and are more efficient in training blind athletes with sprint running numbers by looking at personal abilities and motivation as sprint athletes running norms.

The purpose of this research is to develop a tool for sprint athletes to set the direction in implementing the training program. This study uses the research and development method of Research and Development, namely the research method used to produce certain products and to test the effectiveness of these products. The research was conducted in 3 (three) places, namely 2 (two) schools SLB-A Yapentra and SLB-A Karya Murni and 1 (one) visual blind sprint athlete NPC North Sumatra. From the results of running trials for athletes and guides after the sprint using a remote control and headset, athletes and guides are given a questionnaire and answered according to their respective understanding. Blind athletes filled out a questionnaire assisted by the research team. From the results of a broader field test of 16 blind athletes and 5 guides / coaches, it can be concluded that development of assistive devices for blind sprint athletes meets the criteria, namely 94% -98% can be continued. to the next stage.
