Uphill running represents a frequently used and often prescribed training tactic in the development of competitive distance runners but remains largely uninvestigated and unsubstantiated as a training modality. The purpose of this investigation included documenting the effects of uphill interval training compared with level-grade interval training on maximal oxygen consumption (VO2max), the run...

PURPOSE: To quantify uphill running capacity in a laboratory treadmill test with Swiss elite and junior orienteers, and to evaluate the differences between flat and uphill running capacity. METHODS: 32 elite orienteers (M=18, F= 14) aged 21.8 ± 4.1yr were tested twice to voluntary exhaustion, first in the standard Swiss Olympic lactate threshold test, and second in a graded uphill test at 22% i...

This study aimed to determine whether the fatigue induced by a mountain ultramarathon (MUM) led to changes in energy cost and kinematic during level and graded running. Pre- and post-race, 14 ultratrail runners ran on a level, uphill (5%) and downhill (5%) treadmill at 10 km · h(-1). Kinematic data were acquired using a photocell system. Post-race, the downhill energy cost increased by 13.1% (P...

BACKGROUND We examined aerobic and anaerobic exercise energy expenditure and excess post-exercise oxygen consumption (EPOC) between a 250 Watt, 1-minute bout of cycling and uphill treadmill running. METHODS Fourteen active to well-trained subjects volunteered for the investigation (VO2 max: 57.0 +/- 12.9 ml x kg x min(-1) cycle; 59.3 +/- 13.7 ml x kg x min(-1) run; p = 0.44). Anaerobic energy...

In level running, humans and other animals store and recover elastic energy during each step. What role does elastic energy play during downhill and uphill running? We measured the fluctuations of the mechanical energy of the center of mass (CoM) of 15 human participants running at 3 m s(-1) on the level, downhill and uphill on a force-measuring treadmill mounted at 3, 6 and 9 deg. In level run...

The purpose of this study was to test emotional responses during sprint intervals performed on a level, down and up surface. Fifty trained participants performed a maximal effort during a 60-m sprint and 10 repetitions of 60 m running sprints on a level, down and up surface on a 5.9% slope. Running speeds, emotional responses and heart rate were measured. Self-selected speeds were correlated wi...

AbstractObjectives Recent studies investigated the determinants of trail running performance (i.e., combining uphill (UR) and downhill sections (DR)), while possible specific physiological factors specifically determining UR vs DR performances isolating DR) remain presently unknown. This study aims to determine cardiorespiratory responses outdoor time-trial explo...

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...

PURPOSE Runners use uphill running as a movement-specific form of resistance training to enhance performance. However, the optimal parameters for prescribing intervals are unknown. The authors adopted a dose-response design to investigate the effects of various uphill interval-training programs on physiological and performance measures. METHODS Twenty well-trained runners performed an increme...
