Health Implications of Judo Training

Although current physical activity (PA) guidelines regarding aerobic and anaerobic training are helpful for the population at large, many individuals prefer to engage in alternative forms of PA such as combat sports. As both a martial art and sport, judo is a physically demanding form of PA that potentially offers a novel experience, consequently leading to greater PA adherence. This study aimed to thoroughly search the existing literature to determine the health benefits of judo-specific training. PubMed and Web of Science were searched for original research studies. Only peer-reviewed studies that examined the effects of judo training in males and females aged 18–35 were included in the study. Out of 507 potentially relevant studies, 84 studies met our inclusion criteria and were further analyzed. Data showed that judo athletes and recreational judo practitioners show above-average VO2max, improved body composition, increased bone mineral density, and bone mineral content. Judo is associated with a sequence of adaptations in cardiac structure, function, and blood pressure changes. More research is needed to discover if these changes are maladaptive.

Tomographic Analysis

Changes in the volumetric bone mineral density (vBMD) and bone mineral content (BMC) of tibiotarsal bones of growing turkeys as affected by birds’ age, sex, and within-the-bone location, respectively, were determined by computed tomography. The research was performed on 165 heavy-type BIG 6 turkeys reared between weeks (wk) 3–16 of age. The computed tomography (pQCT) measurement, conducted at 18 and 50% of the bone length, comprised a bone fragment which was 0.07 mm thick for the compact and the spongious substance collectively. It should be noted that the diaphyses of the tibiotarsal bones in turkeys (580 mg/cm3) had greater vBMD than the proximal metaphyses (300 mg/cm3), (P ≤ 0.001). BMC was higher in metaphyses for both sexes. Significant differences between the BMC of the metaphyses and the diaphyses were observed in males and females at wk 3 (P ≤ 0.01), 6 (P ≤ 0.05), and 9 (P ≤ 0.001), and at wk 3 (P ≤ 0.05) and 12 (P ≤ 0.01), respectively. vBMD in the diaphyses gradually attenuated with age for both sexes, from 688 mg/cm3 (wk 3) to 532 mg/cm3 (wk 16). vBMD of the metaphyses was constant in females, but in males it achieved maximum values of 350 mg/cm3 at wk 6 and 12 and minimum of 260 mg/cm3 at wk 9 and 16. Correlations between body weight (BW) and vBMD of the diaphyses were observed in males (r = –0.85, P ≤ 0.001) and females (r = –0.52, P ≤ 0.01). It can be concluded that vBMD loss in diaphyses diminished bone-breaking strength leading in investigated turkeys to deformities and bone fractures.

Mesenchymal stem/stromal cells (MSCs) are known to be useful for treating local bone diseases. However, it is not known if MSCs are effective for treating systemic bone diseases, as the risk for mortality following intravenous MSC administration has hindered research progress. In this study, we compared the safety and efficacy of intra-bone marrow and intravenous administration of MSCs for the treatment of ovariectomy- (OVX-) induced osteoporosis. Cells capable of forming bone were isolated from the murine compact bones and expanded in culture. Relatively pure MSCs possessing increased potential for cell proliferation, osteogenic differentiation, and inhibition of osteoclastogenesis were obtained by magnetic-activated cell sorting with the anti-Sca-1 antibody. Sca-1-sorted MSCs were administered to OVX mice, which were sacrificed 1 month later. We observed that 22% of the mice died after intravenous administration, whereas none of the mice died after intra-bone marrow administration. With respect to efficacy, intravenous administration improved bone mineral density (BMD) by increasing bone mineral content without affecting bone thickness, whereas intra-bone marrow administration improved BMD by increasing both bone mineral content and bone thickness. These results indicate that intra-bone marrow administration of pure MSCs is a safer and more effective approach for treating osteoporosis.

In this study, the authors have analyzed the possible effects of one-year adjuvant treatment with tamoxifen on bone mineral density in postmenopausal breast cancer women. Bone mineral content was studied by photon absorptiometry (I-125), whereas bone balance was analyzed indirectly by serum PTH, osteocalcin, calcitonin, calcium and alkaline phosphatase levels. Bone mineral content and serum bone-related substances were measured before starting treatment and after one year. Results were analyzed using Student's t test for paired data. No difference was found between the two measurements for bone mineral content, PTH, calcitonin, calcium and alkaline phosphatase levels. Measurements at entry and after one year of treatment showed a statistically significant difference ( P < 0.001) only for osteocalcin. In accordance with other authors, we can conclude that treatment with tamoxifen does not cause an increase in menopausal bone resorption. The finding that osteocalcin levels decreased after one year of therapy with tamoxifen is interesting, but further studies are necessary to clarify the role of such levels in predicting a turnover of bone balance towards osteoblastic activity.

The effects of long-term high-protein consumption (i.e., >2.2 g/kg/day) are unclear as it relates to bone mineral content. Thus, the primary endpoint of this investigation was to determine if consuming a high-protein diet for one year affected various parameters of body composition in exercise-trained women. This investigation is a follow-up to a prior 6-month study. Subjects were instructed to consume a high-protein diet (>2.2 g/kg/day) for one year. Body composition was assessed via dual-energy X-ray absorptiometry (DXA). Subjects were instructed to keep a food diary (i.e., log their food ~three days per week for a year) via the mobile app MyFitnessPal®. Furthermore, a subset of subjects had their blood analyzed (i.e., basic metabolic panel). Subjects consumed a high-protein diet for one year (mean ± SD: 2.3 ± 1.1 grams per kilogram body weight daily [g/kg/day]). There were no significant changes for any measure of body composition over the course of the year (i.e., body weight, fat mass, lean body mass, percent fat, whole body bone mineral content, whole body T-score, whole body bone mineral density, lumbar bone mineral content, lumbar bone mineral density and lumbar T-score). In addition, we found no adverse effects on kidney function. Based on this 1-year within-subjects investigation, it is evident that a diet high in protein has no adverse effects on bone mineral density or kidney function.

Background There is substantial evidence that adults with type 1 diabetes have reduced bone mineral density (BMD), however findings in youth are inconsistent. Purpose Systematic review and meta-analysis of BMD in youth with type 1 diabetes using multiple modalities: dual energy X-ray absorptiometry (DXA), peripheral quantitative computed tomography (pQCT) and/or quantitative ultrasound (QUS). Data Sources PubMed, Embase, Scopus and Web of Science from 01/01/1990 to 31/12/2020, limited to humans, without language restriction. Study Selection Inclusion criteria: cross sectional or cohort studies that included BMD measured either by DXA, pQCT and/or QUS in youth (age <20 years) with type 1 diabetes and matched controls. Data extraction Total body (TB), lumbar spine (LS) and femoral BMD (DXA); tibia, radius and lumbar spine (pQCT); and phalanx and calcaneum (QUS). Weighted mean difference (WMD) or standardized mean difference (SMD) were estimated and meta-regression was performed using age, diabetes duration and HbA1c as covariates. Data Synthesis We identified 1300 non-duplicate studies; 46 met the inclusion criteria, including 2617 cases and 3851 controls. Mean age was 12.6 ± 2.3 years. Youth with type 1 diabetes had lower BMD: TB (WMD -0.04 g/cm2, 95% CI -0.06 to -0.02, P=0.0006); LS (-0.02 g/cm2, -0.03 to -0.0, P = 0.01); femur (-0.04 g/cm2, -0.05 to -0.03, P<0.00001); tibial trabecular (-11.32 g/cm3,-17.33 to -5.30, P=0.0002), radial trabecular (-0.91, -1.55 to -0.27, P=0.005); phalangeal (-0.32, -0.38 to -0.25, P<0.00001) and calcaneal (SMD -0.69, -1.11 to -0.26, P=0.001). Using meta-regression TB BMD was associated with older age (coefficient -0.0063, -0.0095 to -0.0031, P=0.002), but not longer diabetes duration or HbA1c. Limitations Meta-analysis was limited by the small number of studies using QUS and pQCT and lack of use BMD z-scores in all studies. Conclusions Bone development is abnormal in youth with type 1 diabetes, assessed by multiple modalities. Routine assessment of BMD should be considered in all youth with type 1 diabetes.
