Building bone strengh in runners
What can we supplement for runners to improve their bone health?
Unfortunately, running is seen as a sport or training modality that increases the resilience and capacity of the bones of the body. Although this does hold some truth, the amount is minimal compared to what could be achieved.
As you can see below, gymnastics was found to be a high bone building activity while we see running categorised as a low osteogenic stimulus.
Several high-quality reviews have shown that increasing running volume with the intention of enhancing bone health is an uphill battle and that:
- Lifting heavy weights and/or
- Maximal jump training improves bone health in pre-menopausal athletes.
Using these modalities can create a buffer when training load increases. Further, the body isn’t subject to the strain that running entails while still gaining benefit.
With consistent training, school and commitments, training time can be sensitive. So, which is most likely to cause an osteogenic, or ‘bone-building response’?
Firstly, either will achieve increased bone resilience. Simply, this happens as the loads from either of these modalities are greater than those of running. Further, as the repetitions are lower, the risk of accumulating bone damage is lower compared to say a 5km or 10km run.
So, let’s look at the studies that performed the training:
Study 1 looked at 4 sets of fast and heavy squats.
3-5 reps @ 85-90% of their 1 rep max.
12-weeks, 3 times a week.
Results of bone mineral density (BMD) after:
2.2% increase in Lumbar Spine in BMD
1% increase in femoral neck in BMD
Study 2 looked at doing 20 jumps, 3 times a day for 6 months with a vest (0-5kg in weight)
Results of bone mineral density (BMD) after:
4.6% increase in Lumbar Spine in BMD
9.8% increase in femoral neck in BMD
So, what does all this mean and what are the take always?
- Jump training is better for the legs & hip, lifting heavy weights is better for the spine. A program that uses both is probably best.
- Both training styles in conjunction with running is an easy and effective way to enhance bone health
- These modalities can be done at home, gym or even in the park so it’s a worthwhile investment
