This article explores the potential of blockchain, AI, and IoT to improve sports performance. Wearable devices are being used to track data such as heart rate, step count, and stride length, and blockchain is being used to generate a tamper-proof and transparent log of all data collected. Smart contracts can also be configured to deliver personalized training regimens or nutritional suggestions depending on each athlete’s unique data points. Medical records, treatment plans, and physiotherapy sessions can be maintained chronologically and accessed by authorized staff using blockchain.
