How important is sleep? Really important.
In this study, cyclists were either allowed normal sleep (about 7.5 hours) or kept sleep deprived (about 4 hours) after a workout.
The result? Sleep deprived cyclists were sleepier (shocker!) and less motivated to train. In addition, their blood pressure had not recovered as much as those who were allowed normal sleep, suggesting less complete recovery from the workout.
These results shouldn't be shocking but they are a good reminder.
I've been going back into the archives a bit recently and this one popped out at me. What does it take to build muscle?
In short, all those things we have usually thought of from weight to number of reps doesn't matter as much as one thing: lifting to failure or near failure.
