“…The cumulative effect of physical activity on BMD must have a certain amount of time to manifest itself, and many factors must be taken into account in the effect of physical activity on BMD, such as type of exercise, intensity of exercise, frequency of exercise, duration of each exercise, and duration of exercise intervention (Qu, 2020). Studies have shown a correlation between grip strength and free fat mass and bone mineral density (Pelegrini et al, 2022), and physical activity capacity was positively associated with hip BMD in both young women and older men, and although it is unlikely to increase BMD, the findings suggest that maintaining a high level of physical fitness and activity may help prevent bone loss in middle-aged and older adults (Hauger et al, 2020), and 8 weeks of power cycling highintensity interval training easily improved physical form in overweight female college students and increased femoral bone mineral density in normal weight female college students (Li et al, 2022). Therefore, adolescents need to reduce body fat and safeguard dietary nutrition through scientific and regular exercise to improve overall bone density (Xu et al, 2021).…”

Background: A sedentary lifestyle with little movement has affected modern youth, and regular exercise has real benefits for people; such studies are mostly for older adults, and more evidence is needed for adolescents.Objective: To compare differences in balance, body composition, and bone mineral density among female college students before and after an exercise intervention to provide precise evidence that exercise promotes college student health.Methods: A whole group of female students in a university was sampled and included in the statistical analysis 50 people, divided into two cohorts, 21 people in the test group and 29 people in the control group; the test group had 4 comprehensive sports activities per week and the control group had 1 comprehensive sports activities per week, and the differences in each index of balance ability, body composition and bone density before and after the intervention were compared after 3 months.Results: After exercise intervention, when maintaining balance, the area of the center of gravity movement trajectory increased by 32.36% in the test group compared with the pre-intervention period and increased by 42.80% compared with the control group, and the differences were all statistically significant (p < 0.01); body mass index (BMI), body fat rate (BFR), visceral fat area (VFA), skeletal muscle content, and Inbody score increased over time more reasonable, and the difference in the effect of time factor (effect) was statistically significant (p < 0.01); bone mineral density (BMD) and BMD Z value increased with time, and the difference in the effect of time factor was statistically significant (p < 0.05).Conclusion: Female college students’ body balance ability improved substantially after exercise intervention; at the university level, female college students had a more rational body composition and continued natural increase in BMD, which were not related to exercise intervention.

“…Further, Han et al ( 65 ) reported that adolescents with greater body mass index showed greater bone mineral density, but this relationship was significant just when they presented greater skeletal muscle mass, calcium supplement intake, and lower body fat mass. In fact, recent evidence indicated that fat mass did not predict adolescent bone mineral density ( 7 ). This evidence is consistent with our finding adjusted for adolescent body weight, and also with our results showing that the mediation effect of ASMI seems to be higher (13.7%) in adolescents with normal-BMI.…”

“…Adolescence is a crucial stage for forming a solid skeleton because the bones grow in size and strength ( 4 , 5 ). The acquired bone mass in this stage (especially in the years around peak height velocity) represents approximately double the amount of bone mineral that subsequently will be lost between the ages of 50–80 years ( 6 ), and it can prevent future diseases of bone fragility such as osteopenia and osteoporosis ( 7 , 8 ). Unfortunately, excess adiposity is unfavorable to bone health in childhood due to the cross-talk between adipose tissue and bone, which regulate each other reciprocally ( 9 ).…”

BackgroundExcess adipose tissue negatively influences bone health during childhood, affecting future bone fragility diseases such as osteoporosis. However, little is known about how adolescent appendicular skeletal muscle mass index (ASMI) may mediate the relation between fatness and bone mineral content (BMC).MethodsThe sample comprised 1,296 adolescents (50% girls) aged 10–14. A principal component analysis was performed to obtain a factor made up of four fatness indicators (a) neck circumference, (b) kilograms of fat, (c) visceral fat area, and (d) waist-to-height ratio. BMC, kilograms of fat, visceral fat area, and appendicular skeletal muscle mass were obtained by a multi-frequency bioelectrical impedance analyzer. ASMI was calculated as the appendicular skeletal muscle mass divided by height squared (kg/m2). A mediation analysis was performed adjusting by age, sex, maturation, socioeconomic status, physical activity, and adolescents' body weight. We also explore differences by sex and nutritional status.ResultsThe fatness factor explained 71.5% of the proportion variance. Fatness was inversely associated with the ASMI and BMC, while the ASMI was positively related to BMC. Overall, the inverse relationship between fatness and BMC was partially mediated by the adolescents' ASMI (29.7%, indirect effect: B= −0.048, 95%CI −0.077 to −0.022), being higher in girls than in boys (32.9 vs. 29.2%). Besides, the mediation effect was higher in adolescents with normal body weight than with overweight-obese (37.6 vs 23.9%, respectively).ConclusionsThis finding highlighted the relevance of promoting healthy habits to reduce fatness and improve muscle mass in adolescents. Moreover, this highlights the central role of ASMI mediating the inverse association between fatness and BMC in female and male adolescents. Public health strategies should promote bone health in childhood, reducing the incidence of early osteopenia and osteoporosis.

“…[3][4][5] Skeletal muscle mass and strength were associated with child and adolescent health as well. Low muscle mass and strength correlated with adverse insulin resistance, 6 cardiovascular risk factors, [7][8][9][10] mental health, 11,12 and low bone mineral density 13 in children and adolescents.…”

The purpose of this study was to evaluate the relationship between dietary zinc intakes and skeletal muscle mass and strength in children and adolescents. A retrospective study was conducted using data on United States adolescents aged 8 to 19 years. Data were extracted from the National Health and Nutrition Examination Survey 2011-2014 cycles. Subjects were divided into 3 groups based on the tertiles of dietary zinc intakes. The levels of appendicular skeletal muscle mass divided by weight (ASM/Wt, %) and grip in subjects with the highest tertile were higher than those in subjects with the middle and lowest tertiles ( P < .05). Dietary zinc intakes were positively correlated with ASM/Wt ( r = .221, P < .001) and grip ( r = 0.169, P < .001). After a multivariate analysis, dietary zinc intakes were still significantly associated with ASM/Wt ( β = 0.059, P < .001) and grip ( β = 0.245, P < .001). The present study demonstrates that dietary zinc intakes were positively associated with skeletal muscle mass and strength in children and adolescents.
