More aerobic volume (i.e. running more miles) is not the only way to improve your running economy.
Periodized strength training, which utilizes the manipulation of variables like sets, repetitions and load, builds the muscular strength that translates to an improvement in running economy.
As your race distance grows, coaches and runners must acknowledge the probabilities of overuse injuries, biomechanic compensations, and fatigue.
Not only does strength training improve running economy, studies also show a decrease in fatigue onset for long-distance athletes who lift.
An increase in muscle strength helps to decrease the time to peak force during muscle contraction leading to increased muscle relaxation. Simply said, an increase in muscle strength can help provide the energy to make each stride more efficient, leading to better blood circulation, improved oxygen uptake and a longer time to exhaustion.
Before you decide to pump some iron, it’s crucial to understand which exercises to implement and how to design a program according to your chosen race distance.
