What are some examples of soft robotic actuators used in wearable exosuits for enhancing human performance in sports and physical activities, and how do they provide assistance, resistance, or augmentation to athletes and fitness enthusiasts to improve endurance, strength, or technique?

Examples include pneumatic muscle actuators, spring-loaded mechanisms, and variable stiffness materials integrated into wearable exosuits or training garments. These actuators apply assistive forces, resistive loads, or adjustable support to muscles and joints, enhancing athletic performance, reducing fatigue, and facilitating skill acquisition in sports training or rehabilitation programs.
