Endurance athletes hormonal responses

Summa measures the body’s fundamental hormonal response to varying training loads and rest. Awareness of this dynamic hormonal response improves training management and is a key to understanding each athlete’s highly individual recovery.

"Summa has given me an insider look at exactly where my body stands during each and every training and racing session. The biggest thing I’ve taken away is that knowing my body is recovering to low evening cortisol levels, day in and day out even after large training and racing sessions. It gives me the confidence knowing in the morning I am going to be recovered and ready for whatever I may ask myself."
