The \"entrapment\" of Vitamin D in adipose tissue due to impaired lipolytic stimulation and\u002For adipose tissue dysfunction has been proposed as the driving mechanism. Exercise training has been proposed as a promising strategy to increase mobilization of Vitamin D from adipose tissue, given its well described role in stimulating lipolysis. Indeed, a recent study revealed that participation in moderate-intensity cardiovascular type exercise over winter can mitigate the decline in 25-hydroxyvitamin D \\[25(OH)D\\] in adults with overweight\u002Fobesity, independent of weight loss. The aim of this study is to investigate the impact of hybrid-type high-intensity interval training over winter on vitamin D metabolism, in adults with overweight\u002Fobesity.",[88,89],"Obesity & Overweight","Vitamin D",[91,92,93,94,95],"overweight","obesity","vitamin D","25-hydroxyvitamin D","high-intensity interval training","2026-05-22",{"date":98,"type":99},"2026-05-26","ACTUAL",{"date":101,"type":99},"2025-11-10",{"date":103,"type":82},"2026-07-20",{"name":5,"class":6},1]
