Muscle and bone mass in middle‐aged women : role of menopausal status and physical activity
2020
Background. Women experience drastic hormonal changes during midlife due to the menopausal transition. Menopausal hormonal changes are known to lead to bone loss and potentially also to loss of lean mass. The loss of muscle and bone tissue coincide due to the functional relationship and interaction between these tissues. If and how physical activity counteracts deterioration in muscle and bone during the menopausal transition remains partly unresolved. This study investigated differences between premenopausal, early perimenopausal, late perimenopausal, and postmenopausal women in appendicular lean mass (ALM), appendicular lean mass index (ALMI), femoral neck bone mineral density (BMD) and T…
Genetics of children's bone growth
2006
Miia Suuriniemi tutki perintötekijöiden vaikutusta murrosikäisten lasten luuston kasvuun ja kehitykseen. Osteoporoosin sukurasitus ei rajoitu koskemaan pelkästään vanhuusiän perinnöllistä luukatoa, vaan vaikutus saattaa ilmetä jo lievinä kasvuhäiriöinä lapsuusiässä. Tietyt perintötekijät saattavat myös altistaa lapsuuden luunmurtumille, jotka omalta osaltaan voivat hidastaa nuoren kasvua, aiheuttaen mahdollisesti jopa pysyviä luustovaurioita.Luusto muodostuu pääosin kollageeniproteiinista, joka antaa luustolle vetolujuutta ja sitkojoustavuutta. Kollageenin rakennetta muuttavat geneettiset mutaatiot aiheuttavat lähes poikkeuksetta harvinaista, mutta vakavaa synnynnäistä luustosairautta, oste…

Targeted exercise against osteoporosis: A systematic review and meta-analysis for optimising bone strength throughout life
2010
Background. Exercise is widely recommended to reduce osteoporosis, falls and related fragility fractures, but its effect on whole bone strength has remained inconclusive. The primary purpose of this systematic review and meta-analysis was to evaluate the effects of long-term supervised exercise (≥6 months) on estimates of lower-extremity bone strength from childhood to older age. Methods. We searched four databases (PubMed, Sport Discus, Physical Education Index, and Embase) up to October 2009 and included 10 randomised controlled trials (RCTs) that assessed the effects of exercise training on whole bone strength. We analysed the results by age groups (childhood, adolescence, and young and …

Training, detraining and bone : effect of exercise on bone mass and structure with special reference to maintenance of the exercise-induced bone gain
2002
The objectives of this thesis were to investigate the effects of long-term mechanical loading on mass, size and mechanical strength of bone in male and female racquet sports players and to evaluate the maintenance of exercise-induced bone gain in these players during the following years of reduced training.
Exercise loading and bone structure
2009
The objective of this dissertation was to determine the types of exercise loading that are associated with the strength of bones. Four cross-sectional studies were conducted between 2004 and 2008 including 378 athletes and their 62 referents. Sixteen different sports were classified into five specific categories for the lower extremities and three categories for the upper extremities according to the type of exercise loading.Besides planar DXA-derived hip structural analysis, pQCT, and MRI methods allowing the assessment of true bone cross-sections were used for the bone structure analyses of the tibia, proximal femur, radius, and humerus. At the lower extremity, the high-impact exercise lo…
