Yes, adrenaline can increase endurance during running by stimulating the release of stored energy in the body, increasing heart rate and blood flow to muscles, and improving oxygen delivery. This can help runners push through fatigue and maintain a higher level of performance for longer periods of time. However, too much adrenaline can also lead to negative effects such as increased heart rate, anxiety, and muscle tension, so it is important to find a balance in adrenaline levels during running. **
