Weighted Vests: Their Impact on Bone Health and Muscle Growth Examined

In recent years, weighted vests have become increasingly popular, with gym-goers, hikers, and social media influencers alike donning these vests to enhance their workouts. The global market for weighted vests is projected to reach $313 million by 2031, driven by growing consumer demand.

However, the scientific community's view on weighted vests is somewhat divided. Roger Fielding, an exercise scientist at Tufts University, states that these vests increase energy expenditure and oxygen consumption. This suggests that they could potentially offer some cardiovascular benefits.

Yet, a small study comparing people walking with weighted vests to those who walked without found no significant difference in bone health. Similarly, the research does not support claims that weighted vests improve muscle and bone strength. Fielding emphasises that walking and running, with or without a vest, do not provide enough stress to significantly grow muscles.

Despite this, Fielding is not entirely dismissive of the potential benefits of weighted vests. If they motivate someone to be more physically active, they can be beneficial. Katie Brodnik, who runs workshops on menopause in Boulder, Colo., finds benefits in wearing a weighted vest and considers it a "tool" for feeling more confident and stronger.

However, concerns have been raised about the potential over-reliance on weighted vests and the neglect of other proven exercises for building strength. Lauren Colenso-Semple, an exercise scientist at McMaster University in Canada, argues that the best way to improve strength is through exercises that use significant resistance and involve the muscle's full range of motion.

The use of weighted vests is particularly popular among women in menopause. Monica Christmas, an OB-GYN in Chicago, recommends weight-bearing exercises for this demographic. However, Nanette Santoro, another OB-GYN in Colorado, expresses suspicion towards people making money off claims to help women in menopause.

Influencers on social media claim that wearing a weighted vest can provide numerous health benefits, such as improved posture, increased calorie burn, and enhanced muscle and bone growth. However, these claims are not yet supported by substantial scientific evidence.

It's worth noting that there is no specific information available about which company currently produces the most weighted vests or what they are working on to expand their market position.

In conclusion, while weighted vests may offer some potential benefits in terms of motivation and cardiovascular health, the evidence for their impact on bone density and muscle strength is limited. As always, it's essential to consult with a healthcare professional before starting any new exercise regimen.
