From the video

Answers: How quickly do runners lose fitness when taking a break from running?

• aerobic fitness
• structural fitness
• VO2 max
• interval training
• cross-training
• strength training

What it concludes

• Aerobic fitness and VO2 max decline much slower than structural fitness during breaks from running.
• Aerobic fitness only decreases by 7 percent on average after 21 days of inactivity in endurance-trained athletes.
• Structural fitness declines much faster than aerobic fitness, leading to stiffness and aches after a week off.
• Incorporating light strength training, stretching, or cross-training during a running break helps maintain structural fitness and prevent injury.
• Resting for 7 to 10 days after a marathon or long run has very little negative effect on fitness and long-term health benefits outweigh fitness loss.
