# Review on Wearable Technology in Sports: Concepts, Challenges and Opportunities
## 8 Challenges and Opportunities
### Remote and Artificial Intelligence Coaching  
The integration of artificial intelligence (AI) and wearable technology has revolutionized the sports landscape, providing real-time data acquisition during training sessions and competitions. These sensors offer access to objective physiological data, enabling the measurement of internal load metrics that were once reliant on expensive and specialized equipment. This data holds immense promise in shaping targeted training programs, refining competition strategies, and even forecasting and preventing injuries for competitive athletes.  
WT has ushered in a new era of data-driven sports coaching, offering coaches and athletes real-time insights into crucial physiological parameters. By leveraging WT, coaches can collect and analyze an unprecedented volume of data, facilitating the fine-tuning of training regimens and making data-informed decisions that maximize an athlete's performance potential while minimizing the risk of injury.  
AI-powered coaching systems have the potential to revolutionize the way athletes receive guidance and feedback. They can analyze vast datasets generated by wearable sensors to provide real-time, data-driven insights into an athlete's performance. AI can identify trends, patterns, and anomalies in an athlete's data, offering personalized recommendations for improvement.  
Coaches are responsible for the physical, psychological, and technical-tactical development of athletes, as well as monitoring their sports performance and health. Nowadays, wearable sensors provide great convenience in obtaining real-time objective physiological data during training sessions or competitions. For instance, they enable the measurement of internal load metrics that require expensive and specialized equipment. Thus, increasing the amount of available data for performance analysis presents significant potential in developing targeted training programs, competition strategies, and predicting/preventinginjuries for competitive athletes. Furthermore, in the future, it is foreseeable that remote coaching systems could evolve without limitations of space and time.  
Despite advancements in AI and WT, the enduring importance of human coaches in the athlete-coach relationship remains essential. The athlete-coach relationship encompasses more than data analysis; it involves mentorship, motivation, and emotional support. The synergy between human coaches and AI coaching systems holds the potential to unlock new dimensions of athlete development and performance excellence. In a recent study [173], the significance of coaches' physical, technical, tactical, and strategic abilities, as well as their subjective reflection, response to feedback, emotional and stress resilience, and neurosocial and neuropsychological aspects, has been demonstrated. Athletes rely on psychological support and verbal feedback from coaches during training sessions or competitions. It should not be forgotten that effective communication skills of coaches and verbal feedback are variables that positively impact both sports performance and social and emotional learning. For these reasons, from a sports performance perspective, it may be more accurate to say that wearable sensors can serve as assistant coaches rather than replace coaches entirely.
