The state of the world's health is critical. Customers seek trustworthy healthcare professionals because the health industry is rife with contradicting information and out-of-date science. Frequently, students are still being taught out-of-date material and a variety of tools without any recommendations for practical application, leaving them feeling overburdened, perplexed, and insecure. Both of these issues were addressed by the invention of functional kinesiology. Kinesiology is the application of the sciences of biomechanics, anatomy, physiology, psychology, and neuroscience to the study of human and animal movement, performance, and function. It examines the mechanisms behind both human and animal movement, with particular attention to the roles played by the skeletal, joint, and muscular systems. Moreover, a foundation and practitioner training pathway is provided by functional kinesiology. The foundation training employs Kinesiology muscle monitoring and the concepts to evaluate the body's energy systems and rebalance them with safe and effective physical, electrical, emotional, and dietary procedures. Sports practice has health benefits in youth and adulthood. Functional kinesiology is about combining the techniques of kinesiology with cutting-edge research in functional nutrition and functional medicine. This method tries to work with the six pillars mentioned above for people to regain their health fully. Among them are diet, adrenals and stress, sex hormones, digestion, and immune and emotional transformation. Given the growing participation of athletes in team and individual sports worldwide, it is necessary to analyze the effect of kinesiology protocols on health and performance. To push forward innovative approaches, this Special Issue calls for original articles, systematic reviews, or meta-analyses that may substantially contribute to data analysis related to functional kinesiology, performance and health. This Research Topic pursues the following goals explicitly: Review of studies related to functional kinesiology of athletes in teenagers and adults. Review of studies on how athletes achieve better health or performance. Review of studies on the quality of training load with bio-motor ability and wellness variables.
