Plyometric training can be a great way to rehabilitate your ankle sprains and improve your functional performance, however, it is essential to monitor your ankle response and progress carefully. Listen to your body - if you feel any pain, swelling, or instability in your ankle, stop the exercise and rest. Start low and slow with low-intensity, low-impact, and low-volume plyometric exercises that are suitable for your injury and fitness level. Do not exceed 10-15 minutes of plyometric training per session, and do not do it more than twice a week. As your ankle heals and strengthens, you can gradually increase the intensity, impact, and volume of your plyometric training. Remember to warm up before with dynamic stretches and low-intensity cardio exercises, as well as cool down after with static stretches and low-intensity cardio exercises. Consult your doctor or physical therapist for more advice and guidance.
