Editorial : children's exercise physiology, volume II

After the previous highly successful Frontiers Research Topic “Children’s Exercise Physiology” (2020), we have challenged the academic community to continue exhibiting their main findings in volume II of this topic. In the past edition, the main topics of research were focused on performance, physical fitness, measurement methodologies, motor competence, overweight and obesity, and pathological subjects. In the current volume II, the Research Topics were less dispersed focusing on two main domains: (i) sports training; and (ii) exercise for health. In the sports training, there was a specific dedication to characterize the physiological demands imposed by the training process in youth soccer players, while the other studies tested relationships between maturation and selection for competition and identified adjusted loads to exercise intervention on the patellar tendon. Regarding the domain of exercise for health, there was a focus on understanding the interactions between exercise and maturation and executive functions in young, while one study focused on understanding the exercise role on fat oxidation. Within this domain, a validation of a motor competence assessment tool was also introduced. Considering the relevance of the topic, we invite our colleagues to follow the read the summary of the evidence presented in our Frontiers Research Topic
