Conversely, running at speeds slower than 2.0 m/s was suggested to be more costly than walking at these speeds. This view was largely unchallenged until the late 1980s. Since that time, several studies have shown that transitioning from walking to running actually resulted in an increase in energy expenditure, while other studies have supported ...
While mainly designed as means of fast space travel, occasionally, some writers have used the hyperspace concept in more imaginative ways, or as a central element of the story.

Strengthening your core can help you to walk with more ease, less soreness, a longer stride and even a faster pace. In addition, cross-training helps to prevent injury due to overuse or repetitive ...
According to Kurzweil, since the beginning of evolution, more complex life forms have been evolving exponentially faster, with shorter and shorter intervals between the emergence of radically new life forms, such as human beings, who have the capacity to engineer (i.e. intentionally design with efficiency) a new trait which replaces relatively ...

For more complex tasks, the relationships between self-efficacy and work performance is weaker than for easier work-related tasks. In actual work environments, which are characterized by performance constraints, ambiguous demands, deficient performance feedback, and other complicating factors, the relationship appears weaker than in controlled ...
