Researchers at the University of Houston in the United States say that penguins can balance gracefully with a skill that humans don't understand and overcome the shortcomings of short legs and heavy weight. The researchers studied the larger emperor penguins. The researchers analyzed the balance principle of penguin walking by measuring the changes of penguin's length and stride. Studying the movement and balance of penguins may help the elderly with walking difficulties learn how to adjust their pace;
I like pregnant women to walk because they are too fat. Swing can save the mechanical energy of penguins, just as a pendulum can keep swinging only when it is initially started. Penguins can save energy by moving slowly from side to side. Like a clock that swings from side to side, a penguin's legs are like a fixed pendulum. Our research results show that this kind of walking is the most expensive for penguins, because their legs are short and they need to produce muscle strength quickly, which requires faster and more muscle fibers.
It snows heavily in winter and the snow is thick. Step on the snow and sink, and lift your feet to move forward. If a person steps on his footprints, it is easier for people behind him to step on his footprints. Stepping on footprints will not be completely accurate, so you will gradually tread a road, but it will never be very wide. Only one person can go there, two people must walk face to face, and they must twist their bodies and miss it; So penguins will walk in columns to prevent collapse.
