Comparisons of Bone Mineral Density Between Recreational and Trained Male Road Cyclists

Abstract

This study suggests road cycling may compromise aBMD and potentially increase the likelihood of low-trauma fractures; health care professionals should consider this exposure when exercise prescriptions are designed for patients at-risk for osteopenia/osteoporosis, for example, women and older adults.

Low Bone Mineral Density and Associated Risk Factors in Elite Cyclists at Different Stages of a Professional Cycling Career

“…For LS BMD Z -score, the final regression model contained BMI, fracture incidence, pBPAQ, CTX-I, 25(OH)D, P1NP, and T3, F ( 7 , 28 ) = 7.825, P < 0.001, adjusted R 2 = 0.46. Past fracture incidence, pBPAQ, and T3 were statistically significant in the final regression model, P < 0.05.…”

“…Low BMD may be even more pronounced in individuals that perform high volumes of cycling exercise training, such as well-trained or elite road-race cyclists (7). To our knowledge, only a few studies assessed BMD in elite cyclists (8)(9)(10)(11)(12)(13).…”

Fragile bones of elite cyclists: to treat or not to treat?

“…Fragile bones of elite cyclists: to treat or not to treat? Luuk Hilkens, 1,6 Pim Knuiman, 2 Mathieu Heijboer, 3 Robert Kempers, 4 Asker E.

This raises the question whether these ostensibly healthy athletes have a higher acute bone fracture risk and a higher risk of osteoporosis and associated comorbidities later in life.…”

Mineral Density of Bone Tissue and Indicators of Bone Remodeling in Highly Skilled Athletes in the Annual Training Cycle

“…Показано, что физическая нагрузка положительно влияет на минеральную плотность костной ткани (МПКТ) [2]. Но повышенные и сверхпороговые нагрузки спорта высших достижений увеличивают напряженность нагрузки на опорно-двигательный аппарат [5], что приводит к росту травм и остеопоротических изменений [5, 19], особенно у профессиональных спортсменов в видах спорта с низкой гравитационной нагрузкой на скелет [14,17]. Костная ткань -динамическая система, где в течение всей жизни происходят процессы костной резорбции и синтеза -процесс ремоделирования, биологический смысл которого состоит в приспособлении свойств кости к меняющимся внешним факторам [12].…”
