铲雪前的准备工作,一定要事前做一些暖身运动。

本文发表在 rolia.net 枫下论坛Prior to Shoveling 铲雪之前:

• Avoid caffeine and nicotine. These are stimulants that place
extra stress on the heart including increasing your heart rate
and causing blood vessels to constrict.

• Avoid eating large meals as it places extra demands on the
digestive system and can lead to stomach cramps.

• Drink plenty of water. Dehydration is just as big an issue in
cold winter months as it is in the summer.

• Dress in several layers so you can remove a layer as
needed. Ensure that you dress warmly in cold weather.

Remember that extremities, such as the nose, ears, hands
and feet need extra attention when it is cold outside. Wear a
turtleneck, sweater, toque, scarf, face protection, wool socks
and waterproof boots. A scarf or other face protection can be
placed over the nose and mouth to avoid breathing cold air.

• Wear proper footwear: Boots with slip-resistant soles can help
to minimize the risk of slips and falls.

Warm up. Before beginning any snow shoveling, warm-up for
five to ten minutes to get the joints moving and increase blood
circulation. To do this, march on the spot, climb stairs, or go for a
quick walk around the block. Follow this with gentle stretches for
the back (knees to chest), arms and shoulders (body hug), and
legs (forward bends from a seated position). This will ensure that
your body is ready for action.
Your back is especially vulnerable when you first wake up. Back
muscles stiffen while you sleep and the discs refill with fluid during
the night. If you attempt to exert yourself shortly after getting out
of bed, you increase the risk of injury. If you plan to head outside
to shovel the driveway, be sure you warm up your lower back first.
Taking a warm shower to loosen stiff muscles and joints can be
quite beneficial.更多精彩文章及讨论,请光临枫下论坛 rolia.net

    • 哪样的雪铲最好?
      Picking the right snow shovel
      The most important features of a shovel include:
      • weight
      • length
      . handle type, and
      • blade size/shape.
    • 整的跟参加奥运会似的
      • 三铁!
        • 还是奥运会容易点
          • looooooooool
      • 当然,铲雪基本是MODERATE的体力活呢。
        The good news is that 15 minutes of light snow shoveling counts
        as moderate physical activity (ACSM, 2005). We should all aim
        for at least 30 minutes of daily moderate physical activity of some
        kind.
        The bad news is that researchers have reported an increase in
        the number of fatal heart attacks among individuals shoveling
        snow following heavy snowfalls. This rise may be due to the
        sudden demand that shoveling places on an individual's heart by
        causing a quick increase in heart rate and blood pressure.
        Who should
      • 你肯定铲雪没问题。。。年轻。。。也壮得像头牛似的。。。
        • 就是这类更要注意,因为他们太自信了。
          • 滑雪比铲雪累
    • 安全铲雪技巧:按照the Canadian Centre for Occupational Health and Safety (CCOHS)的研究, 最好每分钟铲15铲子,而且每15分钟就要休息2到3分钟。
      Shoveling Techniques 安全铲雪技巧。

      What is the recommended rate for shoveling?

      According to the Canadian Centre for Occupational Health and
      Safety (CCOHS), the recommended rate for continuous
      shoveling tasks is considered to be around 15 scoops per
      minute. Tasks involving continuous shoveling at this rate should
      not last for longer than 15 minutes at a time, followed by a rest
      break of at least 2-3 minutes.
      • 露馅了吧 要推 不要铲 不要纸上谈兵
        • 小北哥,鼓励为主,鼓励为主,新年呢,还是。
          • 一看就知道没干过
            • 我们家,这是男生的事儿,女生给煲汤,弄热饮料暖身。 我家同学出差,我们邻居小孩儿代劳,我们给小费+靓汤。 +1
    • 一铲子铲多少重量的雪合适呢?不损害健康呢?
      What is the recommended weight to be lifted?

      The load lifted should be adjusted according to the shoveling rate.
      For a high rate of shoveling (about 15 scoops per minute) the
      total weight (shovel plus a shovel load) should not exceed 5 to 7
      kg (about 10 to 15 Ibs). For a lower rate, the load can be
      increased to a maximum of 11 kg (about 24 Ibs). Wet, heavy
      snow should be lifted in smaller loads as the weight per volume of
      snow is much greater than fluffy, powdery snow.
      • 哪有卖称铲的
        • 你让你的男颜老顽童给你打电话到 the Canadian Centre for Occupational Health and Safety (CCOHS)问。
    • 铲起一铲子雪之后,抛出去的高度及距离多少合适呢?(哇,科学真是科学,不服不行了。)
      What is the recommended throw height and distance?

      Throw height should not exceed 1.3 meters
      (approximately 4 feet). The optimal throw
      distance should be no further than 1 meter
      (approximately 3 feet). The load should be
      reduced if the task requires a longer and/or higher throw.

    • 其实都不用,平常多跑步,练练哑铃或杠铃,铲雪是小意思。。。雪大时要用铲雪机,慢慢铲,别着急。。。
      • 为啥这么严谨?因为因为铲雪而心脏病突发的事情越来越频繁了。华人同学本来平时就不那么爱运动,所以铲雪更需要注意。

              • 所以,你改游泳与骑车了?二黑肯定有内部消息,知道你们男生失去了阵地。
                • 没改 是加 确实这两项目前群骑群游基本都是男同学 挖掘一下内心的断臂山
                  • 为啥不练柔道或者击剑?
                    • 不够柔
            • 你不信北哥呢信二黑?
              挑拨一下LOL
              • 有啥办法,从昨儿开始,只能被迫对二黑另眼相看,因为居然儒雅的多才多艺的方先生爆料:他一直是二黑的粉丝。我只能信二黑了。如果小北哥有重量级粉丝,我再看要不要重新相信他。哈。
                • 重色轻友。。。LOL。。。可怜的小北就这么被抛弃了!
