Soy protein supplementation improves exercise performance, particularly in high-intensity, high-speed, and endurance activities, by delaying fatigue and improving isometric strength.

If you are an athlete, soy protein can help you perform better. It improves endurance, speed, and delays fatigue. It is particularly beneficial after strenuous exercise or muscle damage. You can use it to boost your performance without relying solely on animal proteins or other supplements.

GoodSupportsHIGH confidence
All studies on SP and endurance performance suggested the potential beneficial effects of SP supplementation (10–53.3 g) on exercise performance by improving high-intensity and high-speed running performance, enhancing maximal cardiac output, delaying fatigue and improving isometric muscle strength, improving endurance in recreational cyclists, increasing running velocity and decreasing accumulated lactate levels
