This article offers a promising vision of the future of consumer health technologies, pointing out that many of the currently available devices are classified as "emerging" or "promising". There are clear indications that could have a significant impact on sports performance and the overall health of active people. Future data will become more accurate and reliable, which could allow better customization of training programs, as well as a more accurate assessment of the health and well-being of individuals.

There are smart shin guards "Xseed PRO". They cost a lot (200 euros). They are designed to provide detailed information about the performance of athletes during sporting activity. These shin guards are equipped with advanced sensors that monitor a number of physiological and biomechanical parameters while the athlete trains or competes. The integrated sensors in the Xseed PRO shin guards can detect a wide range of data, including heart rate, acceleration, gait and other parameters relevant to sports performance. What intrigued me most was the ability to recognize the touches of the left or the right. They have its ability to provide real-time feedback to athletes during sports activity. This feedback can be used to optimize training, improve performance and prevent injuries. In addition, data collected from shin pads can be thoroughly analyzed after training or race. This retrospective analysis can help athletes and their coaches identify areas of strength and weakness, as well as develop strategies to improve future performance.

When I took this course of study I always tried to combine it with my passion. I’m a big fan of football and I played semi-professional. Football is probably the most complex sport in the world, there are many quantitative and qualitative variables. For me, who have often found myself in a football field, there is an impossible variable to interpret which is the mental state of the player, which changes many times in a game. Therefore, I think that in order to make the most of the data collected players should always be serene (take the role of psychologist more seriously). Talking about the article, I really liked it, it clarified my ideas and made me see many other things you can do with data. Benfica is now using data analysis very well economically valuing their players to sell them at a higher price. If now the results in the field are seen little does not mean that the analysis of the data is useless because it is only the beginning and in a long time you will see. I think this sentence includes everything "The analysis of sport will most likely change football on the field, but chance will continue to be a determining factor (Lucey et al., 2013: 2706ff)."
