Jump Rope Training for Runners
The surprising impact of 5-minutes per day of skipping on race times.
This study (PMID: 32163923) investigated the effects of incorporating jump rope (JR) training into the warm-up routines of amateur endurance runners. Conducted by a team from various universities, the research sought to determine whether JR can enhance performance metrics such as jumping ability, reactivity, foot-arch stiffness, and overall running performance.
Purpose and Context
The primary purpose of the study was to assess the effectiveness of JR as a plyometric training method to improve key factors associated with endurance running. Previous research has established that plyometric exercises can significantly benefit running performance by enhancing neuromuscular efficiency.
Methodology
Participants: The study involved 96 amateur endurance runners (51 males and 45 females) aged between 18 and 40 years. All participants were recreationally trained and could run 10 km in under 50 minutes.
Design: Participants were randomly assigned to either an experimental group (EG) that incorporated JR into their warm-up (2–4 sessions per week for 10 weeks) or a control group (CG) that maintained their usual warm-up routine.
Training Protocol: The EG replaced 5 minutes of their regular warm-up with JR drills, focusing on technique and minimising ground contact time. The sessions lasted between 10 and 20 minutes weekly.
Testing: Performance was assessed through pre- and post-intervention tests, including a 3-km time trial, jumping tests (squat jump, countermovement jump, drop jump), and measurements of foot-arch stiffness.
Key Findings
Performance Improvements: The EG showed significant improvements in all measured variables compared to the CG:
Enhanced jumping performance.
Increased reactive strength index (RSI).
Improved foot-arch stiffness.
Reduced time in the 3-km time trial.
Statistical Analysis:
Significant pre-post differences were noted in the EG (P < .001), while no changes were observed in the CG.
A Pearson correlation analysis indicated a significant relationship between improvements in RSI and foot-arch stiffness with enhanced time-trial performance.
Regression Analysis: A linear regression showed that changes in RSI and foot-arch stiffness accounted for approximately 39.4% of the variance in improvements in the time-trial performance (R² = .394; P < .001).

Practical Takeaways
Incorporating JR: Amateur endurance runners can benefit from including JR in their warm-up routines to enhance performance metrics without significantly increasing training volume or requiring extensive equipment.
Efficiency: The study suggests that a low-cost, time-efficient training method like JR can yield substantial improvements in running performance, making it an accessible option for many athletes.
Focus on Technique: Proper technique during JR is crucial for maximising benefits, emphasising wrist movement and minimising ground contact time.
