Development and Validation of a PACER Prediction Equation for VOpeak in 10- to 15-Year-Old Youth.

Previous progressive aerobic cardiovascular endurance run (PACER) equations were developed to estimate peak oxygen consumption (VOpeak) from data collected during treadmill running. No equation has been developed using VOpeak assessed during the PACER. To develop and validate a prediction equation to estimate VOpeak from the PACER in 10- to 15-year-olds.

Validity of Physical Activity Monitors for Estimating Energy Expenditure During Wheelchair Propulsion.

Background: It is unknown if activity monitors can detect the increased energy expenditure (EE) of wheelchair propulsion at different speeds or on different surfaces.

Methods: Individuals who used manual wheelchairs (n = 14) performed 5 wheeling activities: on a level surface at 3 speeds, on a rubberized track at 1 fixed speed and on a sidewalk course at a self-selected speed. EE was measured using a portable indirect calorimetry system and estimated by an Actical (AC) worn on the wrist and a SenseWear (SW) activity monitor worn on the upper arm.

Predicting energy expenditure through hand rim propulsion power output in individuals who use wheelchairs.

Aim: To examine the relationship between hand rim propulsion power and energy expenditure (EE) during wheelchair wheeling and to investigate whether adding other variables to the model could improve on the prediction of EE.

Methods: Individuals who use manual wheelchairs (n=14) performed five different wheeling activities in a wheelchair with a PowerTap power meter hub built into the right rear wheel. Activities included wheeling on a smooth, level surface at three different speeds (4.

The ability of the PACER to elicit peak exercise response in youth [corrected].

Purpose: A graded exercise test (GXT) is the standard laboratory method of determining peak aerobic fitness (V˙O2peak). The FITNESSGRAM's Progressive Aerobic Cardiovascular Endurance Run (PACER) test is commonly used to estimate the peak oxygen consumption in the youth in the field.The objective of this study is to compare the peak physiological variables and RPEpeak during a treadmill GXT and the PACER test in 10- to 15-yr-old youths.
