I've Been Saying This for Decades

 

I've been saying it for decades. Sleep time is prime time for maximizing the anabolic and performance enhancing effects of exercise. I stressed optimizing your hormones and providing protein while you sleep over 4 decades ago and practiced what I preached to win my many national, regional and international tittles in powerlifting. Then when I started my own nutritional supplement company in the 1990s I formulated Myosin Protein, which was maximized for night time anabolism, and at the same time introduced NitAbol, a three supplement combo formulated for maximizing night time nutrition. 

 

Decades later there still wasn't any relevant research that backed up what I've been saying all these years. But then that's nothing new as it took decades for research to validate some of my early work on my phase shift diets, and I suspect it will be several more years before research validates the rest. 

 

However, as far as my approach to night time nutrition, a recent paper has backed up what I've been saying about the importance of protein before bed to enhance recovery and increase protein synthesis.

Abstract

INTRODUCTION:

The role of nutrition in modulating postexercise overnight recovery remains to be elucidated. We assessed the effect of protein ingestion immediately before sleep on digestion and absorption kinetics and protein metabolism during overnight recovery from a single bout of resistance-type exercise.

METHODS:

Sixteen healthy young males performed a single bout of resistance-type exercise in the evening (2000 h) after a full day of dietary standardization. All subjects were provided with appropriate recovery nutrition (20 g of protein, 60 g of CHO) immediately after exercise (2100 h). Thereafter, 30 min before sleep (2330 h), subjects ingested a beverage with (PRO) or without (PLA) 40 g of specifically produced intrinsically [1-C]phenylalanine-labeled casein protein. Continuous intravenous infusions with [ring-H5]phenylalanine and [ring-H2]tyrosine were applied with blood and muscle samples collected to assess protein digestion and absorption kinetics, whole-body protein balance and mixed muscle protein synthesis rates throughout the night (7.5 h).

RESULTS:

During sleep, casein protein was effectively digested and absorbed resulting in a rapid rise in circulating amino acid levels, which were sustained throughout the remainder of the night. Protein ingestion before sleep increased whole-body protein synthesis rates (311 ± 8 vs 246 ± 9 μmol·kg per 7.5 h) and improved net protein balance (61 ± 5 vs -11 ± 6 μmol·kg per 7.5 h) in the PRO vs the PLA experiment (P < 0.01). Mixed muscle protein synthesis rates were 22% higher in the PRO vs the PLA experiment, which reached borderline significance (0.059%·h ± 0.005%·h vs 0.048%·h ± 0.004%·h, P = 0.05).

CONCLUSIONS:

This is the first study to show that protein ingested immediately before sleep is effectively digested and absorbed, thereby stimulating muscle protein synthesis and improving whole-body protein balance during postexercise overnight recovery.

While the info on protein intake before bed backs up what I've been saying we're still years away before research catches up to my theories about enhancing the anabolic hormones at the same time to maximize recovery and the anabolic response to exercise.
