Nordic walking

Just for the record .. it was not all grumpiness today.

I went Nordic walking with my big sister. It is so fun to do. Using the arms and legs properly, on top of doing it outside in the sun and wind, makes it a healthy exercise. The whole body unwinds and when the proper conditions are present, you can almost fly.

History 

Nordic walking (original Finnish "Sauvakävely") is fitness walking with specially designed poles. While trekkers, backpackers and skiers had been using the basic concept for decades, Nordic Walking was first formally defined with the publication of "Hiihdon lajiosa" (translation: "A part of cross-country skiing training methodic") by Mauri Repo in 1979.
Nordic Walking's concept was developed on the basis of off-season ski-training activity while using one-piece ski poles.
For decades hikers and backpackers used their one-piece ski poles long before trekking and Nordic walking poles came onto the scene. Ski racers deprived of snow have always used and still do use their one-piece ski poles for ski walking and hill bounding. 

Benefits

Compared to regular walking, Nordic walking (also called pole walking) involves applying force to the poles with each stride. Nordic walkers use more of their entire body (with greater intensity) and receive fitness building stimulation not present in normal walking for the chest, lats, triceps, biceps, shoulder, abdominals, spinal and other core muscles that may result in significant increases in heart rate at a given pace. Nordic walking has been estimated as producing up to a 46% increase in energy consumption, compared to walking without poles.

Equipment

Nordic walking poles are significantly shorter than those recommended for cross-country skiing. Nordic walking poles come in one-piece, non-adjustable shaft versions, available in varying lengths, and telescoping two or three piece twist-locking versions of adjustable length. One piece poles are generally stronger and lighter, but must be matched to the user. Telescoping poles are 'one-size fits all', and are more transportable.
Nordic walking poles feature a range of grips and wrist-straps, or rarely, no wrist-strap at all. The straps eliminate the need to tightly grasp the grips. As with many trekking poles, Nordic walking poles come with removable rubber tips for use on hard surfaces and hardened metal tips for trails, the beach, snow and ice. Most poles are made from lightweight aluminium, carbon fiber, or composite materials. Special walking shoes are not required, although there are shoes being marketed as specifically designed for the sport.

Technique

The cadences of the arms, legs and body are, rhythmically speaking, similar to those used in normal, vigorous, walking. The range of arm movement regulates the length of the stride. Restricted arm movements will mean a natural restricted pelvic motion and stride length. The longer the pole thrust, the longer the stride and more powerful the swing of the pelvis and upper torso."
