The results will show whether there are significant differences between the two groups and whether micro-sleeps contribute to the results. Now that we've spotted a pattern in the material, we're ready to revise. We can add an introduction to present the pattern, organize the material to fit the pattern, and tie the conclusion to the pattern. Research does not give a clear answer to this question. Some studies conclude that loss of sleep affects physical performance adversely, while others indicate that no such effect occurs.
Several studies support the conclusion that sleep deprivation hinders physical performance.
In one study, subjects that were deprived of sleep exhibited less ability in performing physical tasks. In a second study, subjects aged 18-35 deprived of sleep for 72 hours showed progressive losses on physical performances. Sleep deprivation has furthermore been shown to have an effect on homeostasis. As subjects lost sleep the tendency to doze grew stronger, and eventually the subjects nodded off. However, there are studies that refute the idea that sleep deprivation affects physical performance.
