Progressive daily hopping exercise improves running economy in amateur runners: a randomized and controlled trial.

A team led by Engeroff looked at whether daily hopping exercises could improve running economy, a measure of how efficiently runners use oxygen at a given pace. Thirty-four amateur runners were split into two groups, one of which did five minutes of double-legged hopping every day for six weeks, with the difficulty gradually increased over time. The hopping group showed better running economy at the faster speeds tested (12 and 14 kilometers per hour), but not at the slowest speed (10 kilometers per hour).

The improvement was small to moderate in size, and notably, the hopping did not increase their peak oxygen capacity. The findings suggest that plyometric hopping may help amateur runners run more efficiently at moderate to faster paces, though the mechanism behind this effect remains unclear from the study design.

Researchers wanted to know if a simple hopping exercise done every day could help runners run more efficiently, meaning they would need less energy to maintain a given speed. Over six weeks, some runners hopped for five minutes daily while others did their normal training, and then everyone's running efficiency was tested at different speeds.

The runners who did the hopping improved their efficiency when running at faster speeds, which could mean less effort and fatigue during faster runs. However, the improvement was modest rather than dramatic, and it did not make runners able to run faster or harder overall.

The slow jog pace did not show much change for either group, so the benefit seems to appear mainly when running at a quicker clip.

This randomized controlled trial offers a practical finding for clinic populations interested in running efficiency gains. The hopping intervention was simple to deliver, five minutes daily with progressive loading adjustments, and showed a small but statistically significant improvement in running economy at moderate and faster speeds (12 and 14 km/h).

Notably, the effect was speed-dependent, absent at the slowest testing pace, which may suggest the mechanism relates to neuromuscular factors that become more relevant at higher intensities. The study did not show changes in VO2peak, which is consistent with a training stimulus that enhances efficiency rather than capacity.

The increased respiratory exchange ratio at faster speeds warrants interpretation, as it may reflect altered metabolic substrate use rather than improved aerobic function. While the evidence supports considering plyometric hopping as an adjunct for amateur runners, the modest effect size and unclear mechanistic pathway mean this finding is most useful as one tool among several evidence-based approaches rather than a standalone solution.
