 Why should we all skate no matter what our age? Because you get a lot for a little: It's a bargain! One of the greatest active sports that everyone of all ages can participate is skating.
If you can walk, you have enough balance to try skating. Today people of all ages, beginning at two to three years, up to their nineties can skate for fun and fitness. The fun is clearly seen, but the benefits of skating can be somewhat obscure. Walking uses similar muscles as skating and both have their benefits. However, gliding1 across the rink on blades has unusual freedom with ever increasing rewards. Skating burns calories at an increased rate, aids vascular2 cleaning and improves balance. It is well known that walking has benefits for all ages; but there are many more benefits from skating.
Nobody wants to store extra energy as fat so we have to burn a significant portion of what we eat. Some nutrients3 go to replacing wear and tissue; some goes to fat that we must burn or it is stored. One defense4 for this accumulation is to burn the energy during exercise by increasing the work done by the arms and legs. Both the arms and legs are able to consume calories in proportion to their muscle volume. This ratio could be estimated by comparing the volume of these body parts. For example: the thigh5 muscle is roughly ten times the volume of the arm muscle. Thus skating is a much more efficient use of time burning calories.
无论年龄大小，滑冰运动都是最适合大家参与的项目。只要您能够行走，您就能够参与进来。滑冰比散步更能有效的消耗热量，而且滑冰过程中还将享受到那独有的自由惬意，真是乐趣无穷啊。 |
