Its clinical and translational usefulness for sports has increased due to the confluence of wearable technology, physiology, and semiconductor technology. It has been demonstrated that the identification and subsequent use of metrics relevant to and indicative of the athlete's physical performance, physiological state, biochemical makeup, and mental alertness lowers the risk of injury and enhances performance. It has also made it possible for team doctors and trainers to create athlete-centered protocols and treatment plans. In order to give a knowledge of wearable sensors for sports medicine, we address both commercially accessible devices and those that have been reported in scientific literature in this review. The paper determines that innovative approaches to digital monitoring of physical fitness in athletes. This paper's secondary goal is to find joint research opportunities between academic research groups, sports medicine health clinics, and sports team performance programs in order to increase the technology's usefulness in helping athletes return to play across a range of sporting domains. The use of wearables to track an athlete's metabolic profile and mental acuity is covered in a companion study. The overall research found that direct and significant link of innovative approaches on digital monitoring.
