Several internal and external factors have been identified to estimate and control
the psycho-biological stress of training in order to optimize training responses and
to avoid fatigue, overtraining and other undesirable health effects of an athlete.
An increasing number of lightweight sensor-based wearable technologies
(“wearables”) have entered the sports technology market. Non-invasive sensor-based
wearable technologies could transmit physical, physiological and biological data to
computing platform and may provide through human-machine interaction (smart
watch, smartphone, tablet) bio-feedback of various parameters for training load
management and health.
However, in theory, several wearable technologies may assist to control training load
but the assessment of accuracy, reliability, validity, usability and practical relevance
of new upcoming technologies for the management of training load is paramount
for optimal adaptation and health.
