What types of strength training are most effective for runners?

The most effective strength training methods for improving running economy and performance are:

• Heavy Resistance Training (HRT): This involves lifting substantial weights, typically loads exceeding 80% of your 1-Repetition Maximum (1RM), for lower repetitions (e.g., 3-10 reps). It's very effective at increasing maximal strength and improving RE across various speeds.

• Plyometric Training (PT): These are jump-based exercises (e.g., hops, bounds, box jumps) that train your muscles to produce force quickly, enhancing the stretch-shortening cycle. Plyometrics are great for improving reactive strength and RE, particularly at lower to moderate running speeds.

• Combined Methods: Integrating both HRT and PT into your program often yields the largest improvements in performance. This approach targets a broader range of neuromuscular qualities – maximal strength from HRT and reactive strength/power from PT.

Training with lighter, submaximal loads (e.g., 40-79% 1RM for higher repetitions) is generally less effective for boosting running-specific performance and RE in trained runners. Isometric training (contracting muscles without movement) shows some emerging potential but requires more research.
