INSIGHT

Endurance Adaptations to Strength Training

  • Heavy resistance strength training improves endurance performance by increasing 2A muscle fibers.
  • This shift enhances aerobic capacity and fatigue resistance, potentially boosting economy.
INSIGHT

Neuromuscular Function

  • Neuromuscular function improvements from strength training boost force production (MVC) and rate of force development (RFD).
  • Increased MVC reduces fatigue, while improved RFD may prolong relaxation phases.
INSIGHT

Musculotendinous Stiffness

  • Increased musculotendinous stiffness, another strength training adaptation, improves running economy.
  • This stiffness can also be achieved through plyometrics, unlike low-weight, high-rep training.
