Pedometer accuracy during stair climbing and bench stepping exercises.
The purpose of the present investigation was to examine pedometer accuracy during stair climbing and descending as well as during the performance of a bench stepping exercise. Ten healthy men participated in the present investigation. All subjects ascended and descended an 18 cm high public staircase, and performed a bench stepping exercise by using a 10, 20 and 30 cm high platforms, while wear...
متن کاملInfluence of priming exercise on pulmonary O2 uptake kinetics during transitions to high-intensity exercise at extreme pedal rates.
We investigated the pedal rate dependency of the effect of priming exercise on pulmonary oxygen uptake (Vo(2)) kinetics. Seven healthy men completed two, 6-min bouts of high-intensity cycle exercise (separated by 6 min of rest) using different combinations of extreme pedal rates for the priming and criterion exercise bouts (i.e., 35-->35, 35-->115, 115-->35, and 115-->115 rev/min). Pulmonary ga...
متن کاملTemporal Activation of Core Muscles and Vasti in Isolated Patellofemoral Osteoarthritis during Stair-Stepping: A Case-Control Study
Background. Patellofemoral osteoarthritis (PF OA) is a leading cause of significant pain and disability of the knee joint. Stair climbing dysfunction is commonly reported in this cohort. Objectives. To compare the temporal muscle activation between females with PF OA and healthy controls during stair ascent and decide whether there is a link between altered core activity and Patellofemoral oste...
متن کاملPriming exercise speeds pulmonary O2 uptake kinetics during supine "work-to-work" high-intensity cycle exercise.
We manipulated the baseline metabolic rate and body position to explore the effect of the interaction between recruitment of discrete sections of the muscle fiber pool and muscle O(2) delivery on pulmonary O(2) uptake (VO(2)) kinetics during cycle exercise. We hypothesized that phase II VO(2) kinetics (tau(p)) in the transition from moderate- to severe-intensity exercise would be significantly ...
متن کاملEffect of a 15% increase in preferred pedal rate on time to exhaustion during heavy exercise.
The aim of this study was to evaluate the effect of a 15% increase in preferred pedal rate (PPR) on both time to exhaustion and pulmonary O(2) uptake (VO(2)) response during heavy exercise. Seven competitive cyclists underwent two constant-power tests (CPT) at a power output that theoretically requires 50% of the difference in VO(2) between the second ventilatory threshold and VO(2)max (Pdelta5...
