Enhanced Bone Mass and Physical Fitness in Prepubescent Basketball Players

Volleyball and Basketball Enhanced Bone Mass in Prepubescent Boys

“…These effects were more marked in femoral neck BMC and were better observed in SJ and CMJ in VB than BB. These findings are in accordance with results of previous studies, which indicate that bone mass was positively related to physical activity in prepubertal period (19,20) and was dependent on ground forces reactions on bony attachments produced by exercise types (8,9).…”

“…In our study, findings report higher BMC at whole body, weight-bearing (lower limbs, trochanter, and total hip), and nonweight-bearing bones (upper limbs, right third-distal radius and right and left whole radius) in VB and BB than in controls. These results are in accordance with previous studies showing increases in weight-bearing bones BMC associated with prepubertal stages (19,20,27) and in contrast with others which reported a similar BMC (28) and BMD (29) at baseline in all measured sites in prepubescent soccer players and controls. In addition, our VB exhibited greater BMC in both right and left UD radius than controls, while the BB have a similar right and left UD radius BMC to controls.…”

“…In addition, our VB exhibited greater BMC in both right and left UD radius than controls, while the BB have a similar right and left UD radius BMC to controls. These results support the idea that volleyball promoted more additional gain in the forearm bone induced by mechanical stress of technical actions such as (20). We also found that lumbar spine and femoral neck seems to be not sensitive enough to mechanical stress elicited by both volleyball and basketball training.…”

“…However, few studies focused on volleyball and basketball osteogenic effects in children. Cross-sectional analysis reports that previous volleyball and basketball training enhanced BMC and BA in weight-bearing and nonweight-bearing bones in prepubescent athletes than controls (19,20). In our study, findings report higher BMC at whole body, weight-bearing (lower limbs, trochanter, and total hip), and nonweight-bearing bones (upper limbs, right third-distal radius and right and left whole radius) in VB and BB than in controls.…”

“…In highly trained prepubescent VB, Chaari et al (18,19) have shown enhanced bone formation markers and BMC in whole body, lumbar spine, total hip, and radius, accompanied by a BA expansion in radius and weight-bearing sites in comparison with controls. In prepubescent BB, Zribi et al (20) have shown a greater BMC and BA in whole body, upper and lower limbs, total hip, and whole radius than controls. Therefore, our study was conducted first; to verify whether prepubescent boys practicing volleyball or basketball have additional osteogenic effects compared with those obtained from the compulsory school education session; and second to determine which of these 2 high-impact sports is the most osteogenic in prepubertal period.…”
