They say practice makes perfect. Well, another thing practice seems to do is keeping you from getting hurt, at least if you’re a young ball player. Researchers at the University of Kentucky have found that spending time serving up fastballs or throwing out the runner at first can physically alter the shoulders of young athletes, potentially protecting them from future injury. The scientists followed a group of young baseball players between the ages of 13 and 21 for total of 6 years. They found that the active throwing changes the arm bones and soft tissue of the shoulder. This adaptation allows the players to better maintain the ability to rotate that joint as they mature which means faster pitchers with fewer injuries. Of course, too much of a good thing is, you know, not so good. When pitch counts’re too high, or the kids are pushed to play all year-round, their shoulders can be damaged. But the parents of young Roger Clemens want-to-be shouldn’t be too concerned about their toss tendonotomy, the scientists say, they should just use their common sense. So parents, please, protect your precocious pitchers by preventing them from playing through pain to procure the ????

最后一句实在是听不出来了。:loveliness:

Upright-Walking Humans More Efficient Than Chimps  

When it comes to locomotion, being bipedal is not about way to go. This week a team of researchers reports that humans spend only about a quarter of the energy walking on two legs that chimps spend on walking on all fours. The scientists, led by Herman Pontzer of Washington University in St. Louis, measured the amount of oxygen consumed that their subjects walk on the treadmill. They found that chimps XX(what's the verb?) about the same amount of oxygen while they were galloping on all fours or walloping upright. But human volunteers, pound for pound, were more efficient than the chimps. The result appeared on the current issue of the Proceedings of the National Academy of Sciences. One of the chimps, a 33-old female, was actually more efficient touring along on two legs and she wasn't walking on four. This particular ape had a longer stride than the other chimps and being able to get real-want-to go(not sure?) using fewer steps, translating the less energy expenditure. That kind of energy conservation could be what prompted our human ancestors to stand up and strode on their own two feet. If I(不像，但听不出来~~?) even say: the walking upright was our gait way about evolution.

The scientists, led by Herman Pontzer of Washington University in St. Louis, measured the amount of oxygen consumed that their subjects walk on the treadmill. They found that chimps tend to get the same amount of oxygen while they were galloping on all fours of walloping upright. But human volunteers, pound for pound, were more efficient than the chimps. The result appeared on the current issue of the Proceedings of the National Academy of Sciences. One of the chimps, a 33-old female, was actually more efficient touring along on two legs and she wasn't walking on four.

When it comes to locomotion, being bipedal is not a bad way to go. This week, a team of researchers reports that human spend only about a quarter of the energy walking on two legs, that chimps spend on walking on all fours. The scientists, led by Herman Pontzer of Washington University in St. Louis, measured the amount of oxygent consumed that their subjects walk on the treadmill. They found that chimps took in about the same amount of oxygent whether they are galabing on all fours, or widling upright. But human volenteers pound for pound were more efficient than the chimps. The results appeared on the current issue of the Preseen of the National Academy of Sciences. One of the chimps, 33-year-old female, was actually more efficient tooling along on two legs that she wasn't walking on four. This particular ape had a longer stride than the other chimps and being able to get where you wanna go using fewer steps traslates into less energy expenditure. That kind of energy conservation could be what prompted our human ancesters to stand up in strole on their own two feet. You might even say the walking upright was are gateway of evolution.

On #1889, hope my followers can do as I to indicate my dubious points. That will be more clear for discussion and let others know where they shall pay more attention. This will surely take up more of your time but definitely worthwhile as to save even more of the others.
Since we are in, let's do it better.

When it comes to locomotion, being bipedal is not about(a bad) way to go. This week a team of researchers reports that humans(human) spend only about a quarter of the energy walking on two legs that chimps spend on walking(knuckle-walking)on all fours. The scientists, led by Herman Pontzer of WashingtonUniversity in St. Louis, measured the amount of oxygen consumed that(as)their subjects walk(walked) on the treadmill. They found that chimps tend to get(took in about) the same amount of oxygen while(whether) they were galloping on all fours of(or)walloping(wandering) upright. But human volunteers, pound for pound, were more efficient than the chimps. The result appeared on(in) the current issue of the Proceedings of the National Academy of Sciences. One of the chimps,a 33-old(33-year-old) female, was actually more efficient touring along on two legsand(than) she wasn't walking(was knuckle-walking) on four. This particular ape had a longer stride than the other chimps and being able to get real-want-to go(not sure?)(where she want to go)using fewer steps, translating the(translates into "not right in grammar") less energy expenditure. That kind of energy conservation could be what prompted our human ancestors to stand up and strode("not right in grammar but same with me") on their own two feet. You might even say: the(that)walking upright was our gait way about evolution(a gateway of revelution).

Now you can go on with this:

When it comes to locomotion, being bipedal is not a bad way to go. This week a team of researchers reports that human spend only about a quarter of the energy walking on 2 legs that chimps spend knuckle-walking on all 4s. The scientists, led by Herman Pontzer of Washington University in St. Louis, measured the amount of Oxygen comsumed as their subjects walked on a treadmill. They found that chimps took in about the same amount of Oxygen whether they were galloping on all 4s or wandering upright. But human volunteers, pound for pound, were more efficient than the chimps. The results appeared in the current issue of the Proceedings of the National Academy of Sciences. One of the chimps, a 33-year-old female, was actually more efficient touring along on 2 legs than she was knuckle-walking on 4. This paticular ape had a longer stride than the other chimps and being able to get where she want to go using fewer steps, translates into less energy expenditure. That kind of energy conservation could be what prompt our human ancestors to stand up and stode on their own 2 feet.You might even say that walk upright was a gateway of revelution.

A little more help here:   :)

1.   waddle
2.   tool along     figuratively speaking, as if driving a car.
3.   And being able to get where you want to go using fewer steps translates into less energy expenditure.     This is the starting sentence of the last paragraph.
4.   stand up and stroll on their own two feet
