AbstractIntroduction. The study sought to assess bone mineral content (BMC) and bone mineral density (BMD) in men with different levels of physical activity during the period of reaching peak bone massMaterial and methods. The research included wrestlers (n = 31) and students of the University of Physical Education (n = 88) aged 18-24. The state of the bone tissue was assessed with the use of the bone densitometry (DEXA) method (lumbar spine L2-L4). Data concerning the physical activity levels and nutritional behaviours of the study participants were gathered in a diagnostic survey carried out using a specially prepared questionnaire.Results. The analysis of the results revealed that as there were no statistically significant differences in nutritional behaviours between men from particular groups, physical activity proved to be the factor which significantly differentiated the groups under investigation in terms of their bone mass. The highest mean values of the bone parameters analysed were achieved by the wrestlers, who demonstrated a high level of physical activity.

Abstract Summary The aim of the study was to assess the associations of bone mineral density and bone mass with physical activity levels, vitamin D, phosphorus, magnesium, total cholesterol and triglyceride concentration and body composition in young women and men. Physical activity has the most significant effect on bone status especially in men. Purpose The aim of the study was to assess the associations of bone mineral density and bone mass with physical activity levels, vitamin D, phosphorus, magnesium, total cholesterol and triglyceride concentration and body composition in young women and men. Methods One hundred subjects aged 19–24 years were included. Bone mineral density (BMD) in distal and proximal parts was evaluated by forearm densitometry. Body composition was analysed with the use of JAWON-Medical-x-scan. The following biochemical indicators were analysed: 25(OH) D and 1,25(OH)2D, magnesium, phosphorus, total cholesterol and triglycerides. Physical activity levels were assessed by interview. Results Significant correlations between BMD and physical activity, skeletal muscle mass and body fat percentage were revealed in men. Among women, considerably weaker correlations of BMD with body composition and physical activity were noted than in men. BMD in the distal part correlated only with lean body mass, soft lean mass and body fat percentage. The strongest relationship between physical activity and bone mineral status parameters was noted for BMD in men. In women, physical activity did not affect BMD. Conclusions Physical activity has the most significant effect on bone status especially in men.

Turnover Markers

Background:An increased occurrence of lifestyle-related diseases such as osteoporosis indicates the necessity for taking preventive action, including regularly engaging in physical activity. The aim of the study was to assess the areal bone mineral density (aBMD) and bone turnover markers levels in young adult women engaging in recreational horseback riding and to determine the relationship between training characteristics and bone metabolism indices.Methods:The study involved 43 women: 23 equestrians and 20 age- and body mass index–matched controls. The hip and spine aBMD and serum levels of the bone turnover markers: osteocalcin and collagen type I cross-linked C-telopeptide were measured.Results:No significant differences were found in somatic features, concentrations of bone turnover markers, or bone mass variables. Correlation analysis of the equestrian participants showed significant relationship between body mass and BMDL1–L4 (P < .05) as well as between BMI and BMDL1–L4 (P ≤ .01) and z-score L1–L4 (P < .05).Conclusions:The study showed no differences in bone mass and levels of bone metabolic indices between groups of women practicing horseback riding at the recreational level and subjects who do not participate in frequent systematic physical activity. No relationship between training characteristics and bone turnover markers were found.

Local Mechanism

This paper reviews the growth and development of skeletal mass in youth and the effects of physical activity upon the bone mass in young people. The different methods to measure the bone mass are described such as anthropometrics, radiographics, dual energy X-ray absorptiometry, quantitative computed tomography, and ultrasound. Two different mechanisms are important for the formation and plasticity of bone: a central hormonal mechanism (with estrogen production) and a local mechanism (based on mechanical forces of gravity and muscle contractions). This local mechanism is closely connected to physical activity patterns and therefore discussed in more detail. Thereafter the natural course of the development of the bone mass during youth is described, taking into account the pubertal stages of boys and girls and also the age at which the maximal bone mass (peak bone mineral density) will be reached. The last part is devoted to the effects of physical activity on bone mass based on results of randomized controlled trials. Although the number of experimental studies are scarce, significant effects of weight bearing activity and high impact strength training programs are shown on the side specific bone mineral density in both boys and girls.

AbstractDaily school physical activity (PA) improves musculoskeletal traits. This study evaluates whether the benefits remain 4 years after the intervention. We followed 45 boys and 36 girls who had had 40 min PA/school day during the nine compulsory school years and 21 boys and 22 girls who had had 60 min PA/school week (reference), with measurements at baseline and 4 years after the program terminated. Bone mineral content (BMC; g) and bone mineral density (BMD; g/cm2) were measured by dual-energy X-ray absorptiometry and knee flexion peak torque relative to total body weight (PTflexTBW) at a speed of 180 degrees/second with a computerized dynamometer. Group differences are presented as mean differences (adjusted for sex and duration of follow-up period) with 95% confidence intervals. The total gain bone mass [mean difference in spine BMC +32.0 g (14.6, 49.4) and in arms BMD of +0.06 g/cm2 (0.02, 0.09)] and gain in muscle strength [mean difference in PTflex180TBW +12.1 (2.0, 22.2)] were greater in the intervention than in the control group. There are still 4 years after the intervention indications of benefits in both bone mass and muscle strength gain. Daily school PA may counteract low bone mass and inferior muscle strength in adult life. ClinicalTrials.gov.NCT000633828 retrospectively registered 2008-11-03

Moderate to vigorous physical activity plays a recognized osteogenic effect on bone. Moreover, sedentary time, and fat accumulation are unfavorable to bone health. Our study aimed (1) to examine changes in body composition, bone tissue, physical activity, and sedentary time; and (2) to explore whether changes in physical activity intensities and in sedentary time are associated with changes in bone outcomes after a school-based interdisciplinary intervention program. A total of 53 overweight/obese students (10.6 ± 3.5 year-olds; 26 girls) participated in physical activity classes. Bone area, bone mass, and bone mineral density z-score, body composition (fat mass, fat lean mass), physical activity, sedentary time and potential confounders (vitamin D and maturational status) were assessed at baseline, and 8 months later. General Linear Models were carried out and significance level was set at 5%. Changes in moderate to vigorous physical activity were positively correlated with changes in all bone mass indicators. We observed a significant overall effect of the intervention on bone mineral density z-score changes, however after adjustments for changes in sedentary time and moderate to vigorous physical activity, no effect was observed. Finally, variations in sedentary time and in moderate to vigorous physical activity play an important role in bone mass density in those participants of the interdisciplinary program.

Background and objectives: Regular exercise may stimulate bone formation and reduce the loss of bone mass in premenopausal women. This study aims to evaluate the effect of high-impact physical activity (Zumba®) and low-impact physical activity (Aquagym) on bone mass in inactive middle-aged women. Materials and methods: Fifty-five healthy inactive women (30–50 years old) were recruited in Spain in 2016 and were randomly allocated into one of three groups: High impact group (HIG: n = 15), low impact group (LIG: n = 12) and control group (CG: n = 28). HIG and LIG were recruited from Madrid and the CG from Toledo. HIG and LIG completed a 12-week intervention program with three 40′ sessions per week of Zumba® or Aquagym; respectively. Dual energy X-ray absorptiometry (DXA) measured bone mineral content (BMC) and areal bone mineral density (aBMD) at total body less head (TBLH), lumbar spine and right hip. Results: Post-intervention adjusted data showed no significant differences in BMC between any of the groups nor in aBMD between HIG and LIG. Interestingly; significant differences for the HIG vs. CG were found in the change in total hip aBMD (1.76% vs. −0.44%), femoral neck aBMD (1.80% vs. −2.71%), and intertrochanter aBMD (2.03% vs. −0.50%). Moreover, significant differences for the LIG vs. CG were also found in the change in femoral neck aBMD (−0.54% vs. −2.71%). Conclusions: The regular practice of Zumba® and Aquagym might reduce the progressive deterioration of bone mass in inactive middle-aged women
