Thank you Lavanya, for your question on the really important topic of striking the feet. The biomechanics of the feet striking the ground involves a different kind of strength, specifically in the hamstring muscles. This strength, referred to as eccentric strength is not something that develops on its own unless you work on it. Landing the feet hard is not necessary in any speed – but you need strength and stability to do this in a manner that looks impactful (with muscle activation). It might take time and practice to achieve this, but it has safeguarded my joints for a very long time! The downside of repetitive striking of the feet could be degenerative wear and tear or even stress fractures. Let’s put the brakes on this as Bharatanatyam dancers as early as possible. And instead work on getting strong enough to execute the striking without landing hard. Another video on this topic on the Inner Circle perhaps?
