Eccentric Training & Sleep Deprivation

Do you need sleep to produce training goals? 🤷🏻‍♀️⠀⠀⠀⠀⠀⠀⠀⠀⠀
⠀⠀⠀⠀⠀⠀⠀⠀⠀
🤓This study looked at 10 recreationally active men.⠀⠀⠀⠀⠀⠀⠀⠀⠀
They did...⠀⠀⠀⠀⠀⠀⠀⠀⠀
240 eccentric contractions (reps) ➡️ 48 hours no sleep!! ➡️ 12 hours sleep ➡️ tested max strength & blood samples and found:⠀⠀⠀⠀⠀⠀⠀⠀⠀
⠀⠀⠀⠀⠀⠀⠀⠀⠀
👉Max isometric contractions were initially affected by exercise, but recovered at a comparable rate to the control group (3 nights of regular sleep).⠀⠀⠀⠀⠀⠀⠀⠀⠀
👉No measured change in testosterone (a hormone associated with its anabolic [building] properties).⠀⠀⠀⠀⠀⠀⠀⠀⠀
👉Cortisol spiked! Aka: stress levels increased. Too much can be catabolic [breaking down] to the body.⠀⠀⠀⠀⠀⠀⠀⠀⠀
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Ultimately, sleep is important. Whereas a couple nights deprived may have minimal affects on muscle recovery and hormone balances, not getting enough sleep over extended lengths of time can have a major impact your training goals. ⠀⠀⠀⠀⠀⠀⠀⠀⠀
