You will learn about several aspects of your cardiovascular fitness, including:

• Anti-Gravity Running: A form of bodyweight-supported treadmill running that reduces impact forces using suspension or lifting systems (like the LEVER system), allowing you to train with reduced joint stress.

‍

• Bodyweight Support (BWS): A method of offloading a percentage of your body weight during running. Common BWS ranges are 10–40%, used to reduce impact, manage pain, or increase speed safely.
  ‍
• Overspeed Training: A technique where athletes run at speeds beyond their natural max (thanks to BWS), helping improve stride frequency, neuromuscular coordination, and running economy.
  ‍
• Ground Reaction Force (GRF): The force exerted by the ground back onto your body with each step. Anti-gravity systems reduce GRF, making it easier on joints during high-volume or rehab running.
  ‍
• Return to Run Protocol (RTR): A structured progression of reintroducing running post-injury. Anti-gravity running often forms the early phase of RTR to rebuild tolerance gradually and safely.
  ‍
• Running Economy: A measure of how efficiently your body uses oxygen while running. BWS training can improve neuromuscular control and form, contributing to better running economy over time.
  ‍
• Vertical Load Rate (VLR): The speed at which force is applied during foot strike. Reducing vertical load rate is critical in managing bone stress injuries and tendinopathy — and anti-gravity running helps modulate this safely.
  ‍
• Flight Time (FT) & Contact Time (CT): Metrics used to assess stride mechanics. Anti-gravity running allows runners to maintain efficient flight/contact patterns without compensatory mechanics caused by pain or overload.
