Competitive Cheerleading
Over the years, cheerleading has taken two primary forms: game-time cheerleading and competitive cheerleading. Game-time cheerleaders’ main goal is to entertain the crowd and lead them with team cheers, which should not be considered a sport. However, competitive cheerleading is more than a form of entertainment. It is really a competitive sport.
Competitive cheerleading includes lots of physical activity. The majority of the teams require a certain level of tumbling (翻腾运动) ability. It’s a very common thing for gymnasts, so it’s easy for them to go into competitive cheerleading. Usually these cheerleaders integrate lots of their gymnastics experience including their jumps, tumbling, and overall energy. They also perform lifts and throws.
Competitive cheerleading is also an activity that is governed by rules under which a winner can be declared. It is awarded points for technique, creativity and sharpness. Usually the more difficult the action is, the better the score is. That’s why cheerleaders are trying to experience great difficulty in their performance. Besides, there is also a strict rule of time. The whole performance has to be completed in less than three minutes and fifteen seconds, during which the cheerleaders are required to stay within a certain area. Any performance beyond the limit of time is invalid.
Another reason for the fact that competitive cheerleading is one of the hardest sports is that it has more reported injuries. According to some research, competitive cheerleading is the number one cause of serious sports injuries to women. Generally, these injuries affect all areas of the body, including wrists, shoulders, ankles, head, and neck.
There can be no doubt that competitive cheerleading is a sport with professional skills. It should be noted that it is a team sport and even the smallest mistake made by one teammate can bring the score of the entire team down. So without working together to achieve the goal, first place is out of reach.

Take care of your spine (脊柱)
The spine stands at the center of your health, providing your body with structure and support. It also contains your spinal cord, a massive collection of nerves conveying electric signals from the rest of your body to your brain. Since your spine is so central to health, it's important to look after it.
Maintain good posture (姿势)is one of the most important things you can do to keep you spine healthy. Proper posture means standing or sitting while keeping your spine straight, except for its natural curves. Posture comes into play even when you're asleep. Sleeping on you side puts less stress on your spine than most other positions. Staying still for too long----even if your posture is good---can be hard on your back. Especially if you look at a desk most of the day, it's important to get up and stretch periodically.
Exercise is also an important factor in the health of your spine. Stretches can help the muscles around your spine relax and allow bones to shift into better arrangement. Strength exercises like pushups can also help by strengthening the muscles around your spine. However, don't overdo the exercise, as repeated motions can strain the muscles around your spine.
Finally, your diet affects the health of your spine because many vitamins are necessary for bones and nerves. In particular, B vitamins and omega-3 fatty acids keep nerves healthy, so you may want to consider taking a supplement. Another important factor is vitamin D, which is essential for strong bones. Vitamin D can come from some foods, but it's also absorbed from sunlight, so it may help to do some of those back exercises outside.
Many of the actions necessary to keep your spine healthy are identical to those need to preserve your health in other ways. So protect our back, and the rest of body will benefit.
