“…The importance of muscular fitness lies in its inverse association with total and central adiposity and therefore with cardiovascular diseases and metabolic risk factors, and its positive association with bone health [ 15 ] and self-esteem [ 16 ]. Children and adolescents with overweight and obesity show higher maximal muscular strength than children and adolescents with normal weight because the excess of weight involves a chronic training stimulus during the activities of daily living [ 17 ].…”

(1) Background: Childhood obesity is an important public health problem. Children with overweight or obesity often tend to show the pediatric inactivity triad components; these involve exercise deficit disorder, pediatric dynapenia, and physical illiteracy. The aim of the study was to examine the influence of an active video games (AVG) intervention combined with multicomponent exercise on muscular fitness, physical activity (PA), and motor skills in children with overweight or obesity. (2) Methods: A total of 29 (13 girls) children (10.07 ± 0.84 years) with overweight or obesity were randomly allocated in the intervention group (AVG group; n = 21) or in the control group (CG; n = 8). The intervention group performed a 5-month AVG training using the Xbox 360® with the Kinect, the Nintendo Wii®, dance mats, and the BKOOL® interactive cycling simulator, combined with multicomponent exercise, performing three sessions per week. The control group continued their daily activities without modification. Weight, PA using accelerometers, and motor competence using the Test of Gross Motor Development 3rd edition were measured. Muscular fitness was evaluated through the Counter Movement Jump height, maximal isometric strength of knee extension and handgrip strength, and lean mass using Dual-energy X-ray Absorptiometry. Mann–Whitney U and Wilcoxon signed rank tests were performed. The biserial correlation coefficients (r) were calculated. Spearman’s correlation coefficients among PA, muscular fitness, and motor competence variables were also calculated. (3) Results: The AVG group significantly increased their knee extension maximal isometric strength (4.22 kg; p < 0.01), handgrip strength (1.93 kg; p < 0.01), and jump height (1.60 cm; p < 0.01), while the control group only increased the knee extension maximal isometric strength (3.15 kg; p < 0.01). The AVG group improved motor competence and light physical activity (p < 0.05) and decreased sedentary time (p < 0.05). Lean mass improved in both AVG group and CG (p < 0.05). Lastly, the percentage of improvement of motor skills positively correlated with the percentage of improvement in vigorous PA (r = 0.673; p = 0.003) and the percentage of improvement in CMJ (r = 0.466; p = 0.039). (4) Conclusions: A 5-month intervention combining AVG with multicomponent training seems to have positive effects on muscle fitness, motor competence, and PA in children with overweight or obesity.

“…While there is a standardized database reference for the BMD T value of the lumbar vertebrae and hip joint, there is no database comparison for the local BMD of the knee joint. Previous studies have shown no difference in the bone mass between the dominant and non-dominant sides in the lower extremities (23)(24)(25). Analysis of the local bone density of the knee joint for 20 healthy subjects showed similar results in the bilateral legs.…”

Background: Many factors affect the outcomes of anterior cruciate ligament (ACL) reconstruction surgery.However, few studies have examined the effects of local bone conditions on the reconstruction of the ACL.This study investigated the changes in the local bone mineral density (BMD) of the knee after rupture of the ACL with the view of using this information to guide treatment options.Methods: Patients with ACL rupture treated in our department from January 2017 to April 2019 were enrolled in this study. Prior to surgery, local BMD measurements were obtained from all patients and used to determine the appropriate method of ligament fixation. If the local BMD of the affected knee was not significantly lower than that of the healthy side, extrusion fixation was conducted. If the BMD was significantly lower than that of the healthy knee, suspension fixation was applied. The conditions of tunnel cutting or screw splitting, and tunnel enlargement or screw pull-out were observed during the surgery. The post-surgical function of the knee joint was evaluated regularly by physical examination, imaging data, the IKDC scale score, and the Lysholm score.Results: A total of 80 patients with unilateral ACL rupture were included. There were 64 males and 16 females. Decreased BMD was observed in the affected knee compared to the healthy knee for 68 patients.Patients with an ACL history of more than 3 months had lower BMD compared to patients with a history of less than 3 months. Tunnel enlargement and screw pull-out occurred in 2 patients, screw splitting occurred in 1 patient. The fixation mode was adjusted in real-time during the surgery for 3 patients. All patients were followed up for at least 12 months (mean 20.65±5.12 months). The IKDC score increased from 43.07±2.66 pre-surgery to 89.17±3.28 at the final follow-up, and similarly, the Lysholm score increased from 43.49±2.38 pre-surgery to 89.67±2.97 post-surgery. Conclusions:The measurement of local BMD before surgery may play a significant role in guiding the type of graft fixation. It is recommended that patients undergo surgical reconstruction within 3 months after injury.

“…Previous research has shown positive relationships between MBR and performance measures 33 34 . Gomez-Bruton et al 35 , demonstrated differing structural muscle-bone unit ratios (ratio of BMC and LM) between adolescent swimmers and controls, with swimmers demonstrating lower ratios compared to controls. This indicates adolescent swimmers having a lower amount of BMC for similar amount of LM, or similar BMC and higher LM.…”

This study explored body composition in female NCAA Division I rowers compared to controls; and the effect of season, boat category, and oar side on body composition. This retrospective analysis of 91 rowers, and 173 age, sex, and BMI-matched controls examined total and regional fat mass (FM), lean mass (LM), bone mineral content (BMC), bone mineral density (BMD), percent body fat (%BF), and visceral adipose tissue (VAT) measured using dual X-ray absorptiometry. Two-sample t-testing was used to assess differences between rowers and controls. Repeated measures ANOVA analyzed differences across seasons. ANOVA analyzed differences between boat categories. Paired t-testing analyzed oar side versus non-oar side. Rowers had greater height (174.2; 164.1 cm), weight (75.2; 62.6 kg), LM (51.97; 41.12 kg), FM (20.74; 19.34 kg), BMC (2.82; 2.37 kg), and BMD (1.24; 1.14 g/cm2); but lower %BF (30.5%; 27.1%), and VAT (168.1; 105.0 g) than controls (p<0.05). Total, arm, and trunk muscle-to-bone ratio were greater in rowers (p<0.001). Rowers demonstrated greater arm LM (5.8 kg; 5.6 kg) and BMC (0.37 kg; 0.36 kg) in Spring compared to Fall (p<0.05). 1V8 rowers had a lower %BF than non-scoring rowers (25.7%; 29.0%; p=0.025). No differences observed between oar sides. These findings will help rowing personnel better understand body composition of female collegiate rowers.
