Optimal Manner of Measuring Power Across the Lifespan
We will determine when to transition from the common vertical jump to chair stand depending
on age and physical activity levels.
on age and physical activity levels.
Assessing individuals' power, while it is useful in measuring fitness and performance levels,
often requires expensive materials. Vertical jump height has been used to assess peak power
output using specific regression equations. The issue with this test, although it is often
used with older persons, is that it is not practical or useful in assessing the power output
in elderly adults due to possible injury risk and lack of familiarity with providing a
maximal jump performance. Power is important for elderly adults; because, higher power output
in elderly adults has been shown to highly correlate with overall functionality, the ability
to do activities of daily living (ADL), and a reduction in fall probability. A recent study
examined the capacity of a regression equation to quantify power in elderly adults using a
sit-to-stand test and determined; however, the sit-to-stand lacks the difficulty and exhibits
a ceiling effect in younger individuals. Therefore, this study will attempt to determine when
to transition from the vertical jump to the sit-to-stand, so that the differences in
chronological versus physiological age may be determined during aging, and conversely, during
improvements through physical or other interventions.
