About the study

The SKyRoCKeT Study (Surface-Knit and Reformulate CADENCE-Kids for Translation) will recruit a sex- and age-balanced sample of 360 young people 6-20 years of age to develop an integrative, physiologically-coherent age-cadence-log(metabolic equivalent, MET) surface-based model, reformulate the prior R21 CADENCE-Kids study (1; NCT01989104) by providing individualized, more precise, age-specific and coherent cadence-intensity thresholds, investigate additional differences by anthropometric factors, and translate cadence-intensity thresholds to over-ground walking. The SKyRoCKeT Study is an innovative critical step to provide a coherent, interpretable, objectively monitored step-based intensity metric to inform (inter)national physical activity (PA) guidelines by transforming currently vague guidelines of PA intensity into quantifiable PA recommendations that can be of widespread use, which clinicians, young people, parents, and researchers can integrate into preventive care management and action plans for personalized care. The SKyRoCKeT Study will allow for a user-friendly, interpretable metric to more accurately inform public health/behavioral interventions, assessments, analyses, school-based health and physical education curricula and programs, and public health messages for young people and their caregivers.
