BACKGROUND The purpose of this study was to investigate whether uphill treadmill running in rats created histopathological changes within the Achilles tendon consistent with Achilles tendinosis in humans. METHODS Twenty-six mature rats selectively bred for high-capacity running were divided into run and cage control groups. Run group rats ran on a treadmill at a 15° incline for a maximum dura...

Heart Rates at Equivalent Submaximal Levels of VO2 Do Not Differ Between Deep Water Running and Treadmill Running Mercer, John A.; Jensen, Randall L. Journal of Strength & Conditioning Research. 12(3):161-165, August 1998. Objective: To compare submaximal heart rate (HR) and oxygen consumption (VO2) during deep water running (DWR) and treadmill running (TMR). Results: There were no significant ...

Brain cytokines, induced by various inflammatory challenges, have been linked to sickness behaviors, including fatigue. However, the relationship between brain cytokines and fatigue after exercise is not well understood. Delayed recovery of running performance after muscle-damaging downhill running is associated with increased brain IL-1beta concentration compared with uphill running. However, ...

The peripheral nervous system may play an important role in normal bone maintenance and remodeling. Substance P (SP) is a neuropeptide associated with bone loss and formation that may mediate the effects of the nervous system. The purpose of this study is to determine if treadmill running combined with electro-acupuncture at Jiaji acupoints (Jiaji-EA) affects tibial bone mass and SP expression ...

To investigate the time dependence of heart rate variability (HRV) during treadmill running, a feedback control loop was implemented to eliminate potentially confounding influence cardiovascular drift. Without drift, observed changes in HRV can be directly attributed only and not drift-related increases rate. quantify time-dependence HRV, standard metrics for two consecutive windows equal durat...
