Muscle Fatigue & Real-time Recovery

Silent Cicada offers fitness enthusiasts with faster muscle recovery

Implementing a well-rounded approach to recovery is essential in minimizing muscle fatigue and optimizing overall training performance. As your temperature rises beyond the normal range there is a rapid decline in physical and mental capacity. The result is an acceleration of the onset of fatigue combined with poor decision making which can have a negative effect on outcomes. Cold water immersion has become highly regarded for easing muscle stiffness after exercise, dispelling fatigue, diminishing the impacts of exercise-induced muscle damage, and facilitating the return to peak sports performance.

Yet, an effective method to delay the onset of muscle fatigue and accelerate recovery amidst physical exertion remains to be established. The Silent Cicada Personal Air Conditioner presents an innovative approach to combating heat stress by effectively delaying muscle overheating as exercise progresses. This enables athletes to maintain better performance by mitigating heat accumulation in real-time, rather than waiting until after their activity or game is over.

Muscle Fatigue Test (10 Volunteers, Ages 12-40)

Test Activities: Running (distance covered in 2 minutes), dumbbell lifting (number of times a 2.5KG dumbbell was lifted), and hand gripping (number of times a 2KGF grip was achieved).


Utilizing the Silent Cicada Personal Air Conditioner led to improved exercise performance, with a 2% increase in 2-minute running distance, 19% more dumbbell lifts, and a 17% boost in grip endurance. These results indicate the device's potential to enhance resistance training by positively impacting fatigue response, especially when positioned closer to the target muscle group.

This finding resonated with the Strength & Conditioning Research carried out at Stanford University by Professor Craig Heller, who has decades of experience in researching temperature regulation and working in conjunction with the US Military. He developed the Stanford Glove, the first commercial palm cooling device, as shown below. A substantial body of peer reviewed fitness and conditioning research was published by Stanford University and others over a decade. It’s a legal form of performance enhancement on a par with the use of steroids claim Stanford scientists!
