Effect of Level and Downhill Running on Breathing Efficiency
Ventilatory equivalents for oxygen and carbon dioxide are physiological measures of breathing efficiency, and are known to be affected by the intensity and mode of exercise. We examined the effect of level running (gradient 0%) and muscle-damaging downhill running (−12%), matched for oxygen uptake, on the ventilatory equivalents for oxygen (V̇E/V̇Ο2) and carbon dioxide (V̇E/V̇CO2). Nine men (27 ± 9...
متن کاملSpatiotemporal Parameters of Uphill, Level and Downhill Walking Are Similar between Treadmill and Overground Surfaces
Treadmill walking gait analyses are frequently conducted due to their ease of collecting multiple strides of data, minimal space required and ability to finely control speed. The question of whether treadmill (TM) walking gait replicates overground (OG) walking gait on a level surface, has been extensively studied. From a spatiotemporal perspective, TM walking on a level surface generally simul...
متن کاملHow tibiofemoral alignment and contact locations affect predictions of medial and lateral tibiofemoral contact forces.
Understanding degeneration of biological and prosthetic knee joints requires knowledge of the in-vivo loading environment during activities of daily living. Musculoskeletal models can estimate medial/lateral tibiofemoral compartment contact forces, yet anthropometric differences between individuals make accurate predictions challenging. We developed a full-body OpenSim musculoskeletal model wit...
متن کاملTrekking poles reduce downhill walking-induced muscle and cartilage damage in obese women
[Purpose] This study investigated the effect of the use of trekking poles on muscle and cartilage damage and fatigue during downhill walking in obese women. [Subjects and Methods] Subjects included eight obese women who had a body fat percentage greater than 30. Subjects performed downhill walking without a trekking pole (NP) and with a trekking pole (TP) at 50% heart rate reserve for 30 minute...
متن کاملEnergy cost of walking and running at extreme uphill and downhill slopes.
The costs of walking (Cw) and running (Cr) were measured on 10 runners on a treadmill inclined between -0.45 to +0.45 at different speeds. The minimum Cw was 1.64 +/- 0.50 J. kg(-1). m(-1) at a 1.0 +/- 0.3 m/s speed on the level. It increased on positive slopes, attained 17.33 +/- 1.11 J. kg(-1). m(-1) at +0.45, and was reduced to 0.81 +/- 0.37 J. kg(-1). m(-1) at -0.10. At steeper slopes, it i...
