Abstract

A person’s ability to rise from the floor to a standing position is seen as a precursor for establishing and maintaining physical independence. It also is an important primer for the development of other fundamental movement skills (FMS) and is associated with functional capacity in later life. Thus, the potential importance of developing this movement capability early in life and understanding how it may relate to global function (i.e., motor competence-MC and health-related fitness-HRF) across the lifespan may be underestimated. Limited research has examined components or performance (i.e., time) of supine-to-stand (STS) in children to young adults. Further, no previous research has related overall performance on this task to other later developing movement skills and health-related variables. Thus, understanding the role that the development of STS, as a global measure of functional MC, may have on the development of other critical aspects of motor development and function (e.g. fitness) should be examined.

Therefore, two separate studies were conducted. The first study examined the validity of STS as a developmental measure of functional MC across childhood into young adulthood using a pre-longitudinal screen approach and examining associations between movement components and STS time will provide a secondary measure of developmental validity. As well as to examine the concurrent validity of STS (movement patterns and time) against developmentally valid measures of MC (i.e., FMS) in these age groups. Overall, results indicated STS time can be considered a valid and reliable measure of MC across childhood into young adulthood.

The purpose of the second study was to examine the predictive utility of processand product-oriented assessments of STS as a predictor of the health-related variables of PA, weight status and HRF across early childhood into young adulthood. This study is unique in that it is the first to demonstrate the strength of association among STS time, as a measure of functional MC, and health-related measures. Results indicate that higher levels of fitness are associated with faster times to stand. Consequently, more PA data is needed to examine the associations among STS time and PA levels. As the development of STS has been noted as a precursor to physical independence in early childhood and the elderly, its consistent link to cardiorespiratory endurance, muscular strength/endurance, and bodyweight status in early childhood into adulthood provides valuable insight for its potential significance as an early lifespan assessment screening tool.
