The benefits of weight training, in correct dosages, are enormous. Every athlete makes the mistake of not putting back into their body what running takes out. An automobile needs services to maintain it in working order. However, an athlete does not maintain their body in the same way.
Why? When the plain truths are there to be seen by everyone. Strength training adds to avoiding injuries as well as being a proven factor in improving performance. What more could one want, in your pursuit of an injury free running life with personal bests included?
The fears of the negative effects, due to weight training
As mentioned, if you apply weight training correctly there should only be positive effects. Runners need strength from their muscles, not bulk. You do not see a 'bulky' world class marathoner.
Correct weight training will assist in the prevention of injuries, increase muscle endurance, strengthen weak joints and muscles. It will also minimize fatigue in the upper body allowing you to drive further for longer. The aim of any good weight training routine is to help maintain and develop one's body to deal with the stresses of running.
Studies, in the past, show that a runner benefits greatly from a program with more repetitions and less resistance (weight). For runners it is not lifting or using heavy weights, but rather lighter weights or less resistance, repeated 10-12 times each set, with maybe building to 3 sets.
Sprinters and the like may have different needs, but I'm referring to distance runners, or more specifically, 10 km and above. There have been some good studies to support this approach, especially including some plyometric training in the regimen.
Such routines help develop the muscles energy consumption and promotes the synthesis of ATP inside the mitochondria. Mitochondria is best explained as the power station to the cells. The muscles of the upper body will also benefit, which will assist in the 'drive', arm swing, and cadence of the legs. Less repetitions and heavier weights would result in increased muscle mass, and that is bad news. Not if you a sprinter though.
The exercises that do the whole trick
With any good weight training/strengthening
program, one should concentrate on developing the whole body, with
specific attention to the following :
- Legs
- Arms/Chest/Back
- Abdominals
This may look as though you are covering the whole body, we will
only be supplementing the conditioning of the arms, chest and
back. Running is all about efficiency and a strong and conditioned
body will get you to your maximum efficiency.
