“…Downhill running involves lowering the centre of mass within a stride cycle, releasing gravitational potential energy. When compared to flat or uphill running, downhill running is associated with greater impact loads and higher vertical velocity on landing (Gottschall & Kram, 2005; Neves, Johnson, Hunter, & Myrer, 2014), resulting in greater eccentric contractions of the extensor muscles of the lower limbs. Consequently, there is greater potential for elastic energy storage and return (Snyder & Farley, 2011).…”

Running downhill, in comparison to running on the flat, appears to involve an exaggerated stretch-shortening cycle (SSC) due to greater impact loads and higher vertical velocity on landing, whilst also incurring a lower metabolic cost. Therefore, downhill running could facilitate higher volumes of training at higher speeds whilst performing an exaggerated SSC, potentially inducing favourable adaptations in running mechanics and running economy (RE). This investigation assessed the efficacy of a supplementary 8-week programme of downhill running as a means of enhancing RE in well-trained distance runners. Nineteen athletes completed supplementary downhill (-5% gradient; n = 10) or flat (n = 9) run training twice a week for 8 weeks within their habitual training. Participants trained at a standardised intensity based on the velocity of lactate turnpoint (vLTP), with training volume increased incrementally between weeks. Changes in energy cost of running (E) and vLTP were assessed on both flat and downhill gradients, in addition to maximal oxygen uptake (⩒O No changes in E were observed during flat running following downhill (1.22 ± 0.09 vs 1.20 ± 0.07 Kcal kg km, P = .41) or flat run training (1.21 ± 0.13 vs 1.19 ± 0.12 Kcal kg km). Moreover, no changes in E during downhill running were observed in either condition (P > .23). vLTP increased following both downhill (16.5 ± 0.7 vs 16.9 ± 0.6 km h P = .05) and flat run training (16.9 ± 0.7 vs 17.2 ± 1.0 km h, P = .05), though no differences in responses were observed between groups (P = .53). Therefore, a short programme of supplementary downhill run training does not appear to enhance RE in already well-trained individuals.

“…negative work), produces a lengthening action of the musculotendinous system. This was also conveyed by Neves, et al (2014), states that downhill produces greater eccentric contractions of the extensor muscles of the lower limbs. Eccentric contractions play a role in increasing body strength and endurance, by practicing going downhill indirectly the body will adapt and increase endurance, especially in the muscle strength of the lower legs.…”

Short distance running or sprinting is one of the race numbers in athletics. The achievements of sprint runners can be seen from the results of the time they achieve when running on the track. This study aims to determine the effect of uphill and downhill training on the travel time of the 100 meter sprint in the MAN 7 Jombang athletic extracurricular. In addition, to find out the difference in the effect of uphill and downhill training on the travel time of the 100-meter sprint in extracurricular athletics MAN 7 Jombang. The method used in this study is a quasi-experiment with the Two group Pretest and Posttest Design research design. A total of 20 subjects were taken as participants and divided into two exercise groups, each consisting of 10 people. The instrument in this study used a 100 meter sprint test. Then the data that has been obtained will be tested using the Paired Sample Test t test to determine the effect of treatment, Independent sample test t test to analyze the average difference between the two groups. The results showed that (1) There was a significant influence on uphill training and downhill training on the 100-meter sprint travel time in MAN 7 Jombang athletic extracurriculars. (2) There was no significant difference between the uphill and downhill training groups on the 100-meter sprint travel time in the MAN 7 Jombang athletic extracurricular.
