The concept of this thesis not a new one. Accelerometers have been used before in various forms to log accelerations and reaction forces in numerous sports.ADC+UART files is ataached here. The motivations for this can either be in the interests of injury prevention, technique improvement, or both. However, often the hardware is obtrusive and hinders the athlete’s technique, sometimes causing the athlete to alter his or her movement and mask the original problem. The aim of this project is to create an unobtrusive datalogging device to record acceleration profiles with the goal of detecting injury causing abnormalities in technique.-The concept of this thesis is not a new one.
