Test
Our research and development department (DECATHLON SportsLab), in partnership with the Saint-Etienne university, has conducted a study on a panel of testers to check the effects of compression during running. This study has shown that wearing Kalenji sleeves when running improves a runner's blood flow by 47%. Wearing KALENJI sleeves when running boosts the oxygenation of the runner's muscles and legs.
