Dual X-ray absorptiometry provided total\n                    and regional (i.e., arm, leg, trunk) lean mass (LM), fat mass (FM), and bone\n                    mineral content (BMC). MBR was calculated by dividing LM by BMC. The SBR was\n                    calculated by dividing LM+FM by BMC. Kruskal-Wallis tests were used to compare\n                    ratios across event groups. Dunn\u2019s post-hoc tests were utilized to adjust for\n                    multiple comparisons. Total MBR for females was higher in the throwers compared\n                    to the multievent athletes (p=0.02). For the males, total MBR was lower in\n                    jumpers compared to all events except pole vaulters (PV) (p&lt;0.05). Trunk MBR\n                    was higher in the long-distance runners (LD) compared to jumpers, PV, and\n                    throwers (p&lt;0.05). The throwers had higher total, arm, and leg SBRs compared\n                    to the jumpers, LD, middle distance, PV, and sprint groups (p&lt;0.05).\n                    Significant differences in total and regional MBR and SBR were identified across\n                    event groups for both sexes, and may indicate event-specific adaptations\n                    impacting the balance between soft tissue and bone. <\/jats:p>","DOI":"10.1055\/a-2445-9582","type":"journal-article","created":{"date-parts":[[2025,2,4]],"date-time":"2025-02-04T23:44:36Z","timestamp":1738712676000},"page":"90-96","source":"Crossref","is-referenced-by-count":4,"title":["Muscle-to-bone and soft tissue-to-bone ratios in track and field\n                    athletes"],"prefix":"10.1055","volume":"46","author":[{"given":"Hannah","family":"Westerberg","sequence":"additional","affiliation":[{"name":"Kinesiology, University of Minnesota, Minneapolis, United\n                    States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip R.","family":"Stanforth","sequence":"additional","affiliation":[{"name":"Department of Kinesiology and Health Education, University of Texas at\n                    Austin, Austin, United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aaron","family":"Carbuhn","sequence":"additional","affiliation":[{"name":"Kansas Athletics, University of Kansas, Lawrence, United\n                    States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tyler","family":"Bosch","sequence":"additional","affiliation":[{"name":"Red Bull, Performance and Data Analytics, Athlete Performance Center,\n                    Santa Monica, California, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donald R","family":"Dengel","sequence":"additional","affiliation":[{"name":"Kinesiology, University of Minnesota, Minneapolis, United\n                    States"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2025,2,4]]},"reference":[{"key":"ref1","first-page":"173","article-title":"Physical activity and bone: The importance of the various mechanical stimuli for\n                    bone mineral density","volume":"20","author":"B Morseth","year":"2011","journal-title":"A review.
