(1) Background: Poor levels of physical fitness and motor skills are problems for today’s children. Active video games (AVG) could be an attractive strategy to help address them. The aim was to investigate the effects of AVG on health-related physical fitness and motor competence in children and adolescents with healthy weight. (2) Methods: Randomized and non-randomized controlled trials investigating the effects of AVG programs on health-related physical fitness and motor competence were included. Two different quality assessment tools were used to measure the risk of bias. Twenty articles met the inclusion criteria and the variables of interest were body mass index (BMI), body fat, cardiorespiratory fitness (CRF), muscular fitness and motor competence. (3) Results: AVG interventions seem to have benefits in BMI when lasting longer than 18 weeks (SMD, −0.590; 95% IC, −1.071, −0.108) and in CRF (SMD, 0.438; 95% IC, 0.022, 0.855). AVG seems to be a promising tool to improve muscular fitness and motor competence but the effects are still unclear due to the lack of evidence. (4) Conclusions: AVG seem to be an effective tool for improving some components of health-related physical fitness and motor competence in healthy-weight children and adolescents, but the effect on some fitness components needs further research. Therefore, AVG may be included as a strategy to improve health.

The main objective of this study was to device-assess the levels of physical activity and sedentary behaviour patterns of older adults during the situation prior to the COVID-19 pandemic, home confinement, and phase-0 of the deescalation. We also aimed to analyse the effectiveness of an unsupervised home-based exercise routine to counteract the potential increase in sedentary behaviour during the periods within the pandemic. A total of 18 noninstitutionalized older adults( 78.4 ± 6.0 y.), members of the Spanish cohort of the EXERNET-Elder 3.0 project, participated in the study. They were recommended to perform an exercise prescription based on resistance, balance, and aerobic exercises during the pandemic. Wrist triaxial accelerometers (ActiGraph GT9X) were used to assess the percentage of sedentary time, physical activity, sedentary bouts and breaks of sedentary time. An ANOVA for repeated measures was performed to analyse the differences between the three different periods. During home quarantine, older adults spent more time in sedentary behaviours ( 71.6 ± 5.3 % ) in comparison with either the situation prior to the pandemic ( 65.5 ± 6.7 % ) or the ending of isolation ( 67.7 ± 7.1 % ) (all p < 0.05 ). Moreover, participants performed less bouts of physical activity and with a shorter duration during home quarantine (both p < 0.05 ). Additionally, no differences in the physical activity behaviours were found between the situation prior to the pandemic and the phase-0 of deescalation. According to our results, the home confinement could negatively affect health due to increased sedentary lifestyle and the reduction of physical activity. Therefore, our unsupervised exercise program does not seem to be a completely effective strategy at least in this period.

Childhood obesity has become a major global health problem. Vitamin D deficiency and poor cardiorespiratory fitness are highly prevalent in children with overweight or obesity, but little is known about their relationships. In this study, we aimed to analyze the relationship between serum 25-hydroxyvitamin D (25(OH)D) and cardiorespiratory fitness parameters in prepubertal obese and overweight children. A cross-sectional design with a sample of 57 prepubertal children, aged 9–11 years, with overweight or obesity was used. The fasting concentration of 25(OH)D was analyzed with a chemiluminescent microparticle immunoassay. Fat and lean body masses were determined by using DXA. Maximal oxygen uptake (VO2max) was measured with the maximal treadmill test. A total of 68.4% of the sample had sufficient levels of 25(OH)D. As expected, their cardiorespiratory fitness was poor compared with that of normal-weight children, but 60% of the group exceeded the median obesity-specific reference values. No differences were found between the sexes for relative VO2max or 25(OH)D levels. Moreover, no correlations were found between 25(OH)D and body composition or cardiorespiratory parameters for sex or vitamin D groups. Vitamin D status seems not to be directly related to body composition or cardiorespiratory fitness in prepubertal overweight or obese children.

BACKGROUND Childhood obesity is one of the most important public health problems of the 21st century and active-video games have been proposed as a good alternative to exercise and are being investigated to find out their effectiveness against childhood obesity. OBJECTIVE to summarize the current research and extract conclusions about the effects of active video games on health-related physical fitness and motor competence in children and adolescents with overweight and obesity. METHODS The search strategy was applied to PubMed, Medline, Web of Science and SPORTDiscus, including randomized and non-randomized controlled trials investigating the effects of programs using active video games on health-related physical fitness and motor competence of children and adolescents with overweight and obesity. Two different quality assessment tools were used to measure the risk of bias for randomized and non-randomized controlled trials. Fifteen articles met the inclusion criteria and the variables of interest were body mass index, body fat percentage, cardiorespiratory fitness, waist circumference, fat-free mass, muscular fitness and motor competence. A meta-analysis was performed. RESULTS Positive effects were found for body mass index and body fat percentage, favouring the active video games group compared with a control group with no intervention (MD, -0.209; 95% IC, -0.388, -0.031; an d MD, -0.879; 95% IC, -1.138, -0.602, respectively). Positive effects seem to be found for cardiorespiratory fitness. The effects of interventions with active video games on muscular fitness, fat-free mass and waist circumference and motor competence are unclear. CONCLUSIONS Programs using active video games showed positive effects on body mass index, body fat percentage and cardiorespiratory fitness. Active video games could be a good strategy to fight against childhood obesity. CLINICALTRIAL A protocol was registered in the International Prospective Register of Systematic Reviews, PROSPERO (CRD42020189138).

The aim of this study was to evaluate bone health and body composition by dual-energy X-ray absorptiometry (DXA) in individuals with Cornelia de Lange Syndrome (CdLS). Overall, nine individuals with CdLS (five females, all Caucasian, aged 5–38 years) were assessed. Total body less head (TBLH) and lumbar spine (LS) scans were performed, and bone serum biomarkers were determined. Molecular analyses were carried out and clinical scores and skeletal features were assessed. Based on deep sequencing of a custom target gene panel, it was discovered that eight of the nine CdLS patients had potentially causative genetic variants in NIPBL. Fat and lean mass indices (FMI and LMI) were 3.4–11.1 and 8.4–17.0 kg/m2, respectively. For TBLH areal bone mineral density (aBMD), after adjusting for height for age Z-score of children and adolescents, two individuals (an adolescent and an adult) had low BMD (aBMD Z-scores less than –2.0 SD). Calcium, phosphorus, 25-OH-vitamin D, parathyroid hormone, and alkaline phosphatase levels were 2.08–2.49 nmol/L, 2.10–3.75 nmol/L, 39.94–78.37 nmol/L, 23.4–80.3 pg/mL, and 43–203 IU/L, respectively. Individuals with CdLS might have normal adiposity and low levels of lean mass measured with DXA. Bone health in this population seems to be less of a concern during childhood and adolescence. However, they might be at risk for impaired bone health due to low aBMD in adulthood.

Therefore, our unsupervised exercise program does not seem to be a completely effective strategy at least in this period.What is already known on this topicAlthough the available information is scarce and includes subjective methodology (questionnaires), it seems that the COVID-19 pandemic has negatively affected physical activity patterns.It is known that physical activity interventions are effective in improving health and reducing sedentary lifestyle in older adults. Nevertheless, little is known about whether an unsupervised home-based exercise routine is an effective alternative to counteract the potential increase in sedentary behaviour in this specific population during the pandemic lockdown.What are the findings? / What this study addsDespite unsupervised training, during home-quarantine, older adults spent more sedentary time than in the situation prior to COVID-19 and the ending of isolation (phase 0).There were no differences in break of sedentary time patterns between the situation prior to COVID-19 and the periods within the pandemic.During home-quarantine older adults performed fewer and shorter physical activity bouts than in the situation prior to COVID-19 despite unsupervised training.Our unsupervised home-exercise routine was not a completely effective alternative to avoid the increase of sedentary behaviour during home-quarantine.How might it impact on clinical practice in the future?Our findings can be used as a starting point to manage isolation restrictions more effectively and to develop strategies to promote physical activity and reduce sedentary behaviour among older adults during situations of forced lockdowns, as in the present COVID-19 pandemic.

(1) Background: Childhood obesity has become a main global health problem and active video games (AVG) could be used to increase energy expenditure. The aim of this study was to investigate the energy expenditure during an AVG intervention combined with exercise, differentiating by gender. (2) Methods: A total of 45 children with overweight or obesity (19 girls) performed an AVG intervention combined with exercise. The AVG used were the Xbox Kinect, Nintendo Wii, dance mats, BKOOL cycling simulator, and Nintendo Switch. The energy expenditure was estimated from the heart rate recorded during the sessions and the data from the individual maximal tests. (3) Results: The mean energy expenditure was 315.1 kilocalories in a one-hour session. Participants spent the most energy on BKOOL, followed by Ring Fit Adventures, Dance Mats, Xbox Kinect, and the Nintendo Wii, with significant differences between BKOOL and the Nintendo Wii. Significant differences between boys and girls were found, but were partially due to the difference in weight, VO2max, and fat-free mass. (4) Conclusions: The energy expenditure with AVG combined with multi-component exercise was 5.68 kcal/min in boys and 4.66 kcal/min in girls with overweight and obesity. AVG could be an effective strategy to increase energy expenditure in children and adolescents with overweight and obesity.

To analyze the incidence and injury pattern in Spanish football (soccer) referees. In this retrospective study, Spanish referees filled out an online survey during a training camp organized by the Referees Technical Committee of the Real Federación Española de Fútbol. The survey included questions on aspects of refereeing qualifications, training and matches, injury patterns (type, location, and circumstances), and absence of the 2018–2019 season. A total of 28 elite referees (24.1%) out of 116 reported having suffered one injury during the season. Significant differences in the frequency of injuries between match (MRs) and assistant referees (ARs) were observed. MRs were 1.90 (95% CI 1.008–3.582) times as likely to suffer an injury compared to ARs. The incidence of match injuries for MRs officiating in the top division of the Spanish Football League was 1.30 (95% CI 0.0–3.82) per 1000 match hours while for ARs was 0.7 (95% CI 0.0–2.1); the incidence of training injuries was considerably lower in both groups (0.4 (95% CI 0.0–0.9) vs. 0.3 (95% CI 0.0–0.6). Hamstring- and calf-related muscle problems were the most common injury diagnoses in elite referees. Injured referees had, on average, 2 weeks of absence from training and competition. Elite MRs had a 90% increase in the risk of suffering an injury in comparison with elite ARs. The incidence of match injury or training injury was very low in both groups, despite that, they should continue carrying out preventive programs specially targeted for hamstring- and calf-related muscle problems.

Regions of the proximal femur with less adaptive protection by mechanical loading may be at increased risk of structural failure. Since the size and location of these regions diverge from those defined by the dual-energy X-ray absorptiometry manufacturers the purpose of this study was to compare areal bone mineral density (aBMD) of different regions of the proximal femur considering impact loads from physical activity (PA). The participants were 134 young adults divided into 2 groups according to the impact of PA performed in the last 12 mo: high-impact PA and low-impact PA. The aBMD of the proximal femur was assessed by dual-energy X-ray absorptiometry at the standard femoral neck, intertrochanter, and trochanter, and at specific locations of the superolateral femoral neck and intertrochanteric region. The bone-specific physical activity questionnaire was used to estimate the impact load of PA. Comparisons between groups were adjusted for body height and body lean mass. Interaction analysis between sex and PA groups were conducted with analysis of variance. Comparisons of aBMD between bone regions were analyzed separately for men and women with repeated measures analysis of variance. In the high-impact PA group, men benefit more than women at all bone regions, except the aBMD at intertrochanteric region. Analyses of repeated measures did not reveal any significant interaction effect between bone regions (standard vs specific) and PA groups (low vs high-impact). In conclusion, aBMD differences due to mechanical loading were more pronounced in men than in women; the magnitude of the aBMD differences as a result of different levels of PA was similar between standard and localized regions.

The aims of this study were (a) to determine which of the most used anthropometric equations was the most accurate to estimate percentage of body fat (%BF), (b) to develop a new specific anthropometric equation, and (c) to validate this football-specific equation. A total of 126 (13.3±0.6 y) football players (86 males) participated in the present study. Participants were divided into two groups: 98 players were included in the assessment of existing equations and in the development of the new prediction equation; and 28 were used to validate it. %BF was measured with dual-energy X-ray absorptiometry (DXA) and also estimated with six different %BF anthropometric equations: Johnston, Slaughter, Carter, Faulkner, Deurenberg and Santi-Maria. Paired t-tests were used to analyze differences between methods. A football-specific equation was developed by a stepwise linear-regression. The existing anthropometric equations showed significant bias for %BF when compared to DXA (p<.001; constant error [CE] ranged from -4.57 to 9.24%; standard error of estimate [SEE] ranged from 2.46 to 4.20). On the other hand, the developed football-specific equation was %BF = 11.115 + 0.775(triceps skinfold) + 0.193(iliac-crest skinfold) – 1.606(sex). The developed equation demonstrated neither %BF differences (p=.121; CE=0.57%; SEE=0.36) when compared to DXA, presenting a high cross-validation prediction power (R2=0.85). Published anthropometric equations were not accurate to estimate %BF in adolescent football players. Due to the fact that the developed football-specific equation showed neither differences nor heteroscedasticity when compared to DXA, this equation is recommended to assess %BF in adolescent football players.

The present study shows that football practice during growth may improve bone geometry in male and female football players. However, only females had better bone strength in comparison with controls. The aim of this study was to compare bone geometry in adolescent football players and controls. A total of 107 football players (71 males/36 females; mean age 12.7 ± 0.6/12.7 ± 0.6 years) and 42 controls (20 males/22 females; mean age 13.1 ± 1.4/12.7 ± 1.3 years) participated in this study. Total and trabecular volumetric bone mineral content (Tt.BMC/Tb.BMC), cross-sectional area (Tt.Ar/Tb.Ar), and bone strength index (BSI) were measured at 4% site of the non-dominant tibia by peripheral quantitative computed tomography (pQCT). Moreover, Tt.BMC, cortical BMC (Ct.BMC), Tt.Ar, cortical Ar (Ct.Ar), cortical thickness (Ct.Th), periosteal circumference (PC), endosteal circumference (EC), fracture load in X-axis, and polar strength strain index (SSIp) were measured at 38% site of the tibia. Multivariate analyses of covariance were used to compare bone pQCT variables between football players and controls using the tibia length and maturity offset as covariates. Female football players demonstrated 13.8-16.4% higher BSI, Ct.Th, fracture load in X-axis, and SSIp than controls (p < .0036). Males showed no significant differences in bone strength when compared to controls (p > .0036). In relation to bone mineral content and area, male football players showed 8.8% higher Tt.Ar and Tb.Ar at the 4% site of the tibia when compared to controls; whereas 13.8-15.8% higher Tt.BMC, Ct.BMC, and Ct.Ar at the 38% site of the tibia were found in female football players than controls (p < .0036). In this study, female adolescent football players presented better bone geometry and strength values than controls. In contrast, only bone geometry was higher in male football players than controls.

Background Swimming has no effect on bone mass or structure. Therefore, adolescent swimmers present similar bone strength values when compared to normo‐active controls, and lower values when compared to weight‐bearing athletes. It thus seems necessary to try to improve bone structure and strength of adolescent swimmers through a weight‐bearing intervention in order to reduce the risk of suffering osteoporosis later in life. Objective To evaluate the effects of a 6‐month whole body vibration (WBV) intervention on bone strength and structure of adolescent swimmers. Design Randomized controlled trial. Setting Research center. Participants A total of 51 swimmers (14.4 ± 2.0 years) participated in the study. Methods Swimmers were randomly allocated into 2 groups: 20 swimmers (9 females) who only performed their swimming training, and 31 swimmers (15 females) who performed their swimming training and received a WBV intervention (3.6‐11.6 g) 3 times per week during 6 months (VIB). Outcome measurements Peripheral quantitative computed tomography was performed in the nondominant tibia of all swimmers at 4%, 38%, and 66% of the tibia length before and after the intervention. Results No differences between groups in any bone structure variable were found at pre‐ or postintervention. Both groups presented similar improvements in time, and no group by time interactions were found, suggesting that the WBV intervention was not intense enough to achieve positive changes in bone strength or structure. Conclusion WBV, at the chosen intensities and durations, had no effect on adolescent swimmers' bone strength or structure. Future studies should test other weight‐bearing interventions aiming to improve bone strength and structure of adolescent swimmers. Level of Evidence II

Swimming has little effect on bone mass. Therefore, adolescent swimmers should complement their water training with a short and intense weight-bearing training, aiming to increase their bone acquisition. Forty swimmers performed a six-month whole-body vibration (WBV) training. WBV had no effect on adolescent swimmers’ bone mass or lean mass. The aims of the present study were to evaluate the effects of a whole-body vibration (WBV) intervention on bone mineral density (BMD), bone mineral content (BMC) and lean mass (LM) in adolescent swimmers. Forty male and female adolescent swimmers (VIB; mean age 14.2 ± 1.9 years) completed the WBV protocol that consisted of 15 min of training 3 days per week during a 6-month period (ranging from 3.6 to 11.6 g), while 23 swimmers (SWI; mean age 15.0 ± 2.2 years) continued with their regular swimming training alone. VIB were divided into tertiles according to training compliance in order to evaluate if any dose-effect relation existed. BMD, BMC and LM were measured longitudinally by dual energy X-ray at the whole body, lumbar-spine and hip. No group by time interactions and no differences in change percentage were found for BMD, BMC or LM in any of the measured variables. The mean change percentage of the subtotal body (whole body minus the head) for VIB and SWI, respectively, was 2.3 vs. 2.4% for BMD, 5.7 vs 5.7% for BMC and 7.3 vs. 8.0% for lean mass. Moreover, no indication for dose-response was observed. The proposed WBV protocol had no effect on BMD, BMC and LM in adolescent swimmers. Other types of training should be used in this population to improve both bone and lean mass.

Introduction: The hand grip strength test provides useful and reliable information about overall health. Different studies have investigated the optimal grip span for determining maximal hand grip strength in different populations such as adults, adolescents and children without disabilities. Objective: To ascertain whether there is an optimal grip span for determining maximal hand grip strength in adolescents with Down syndrome (DS). Methods: Twenty-seven right-handed youths with DS (seven females) aged 15.5 ± 3.6 years were evaluated in this methodological study. Each hand was randomly tested on ten times using five different grip spans, allowing one-minute rest between attempts. The hand span was measured from the tip of the thumb to the tip of the small finger with the hand widely opened. To confirm the usefulness of the optimal grip span, a new group of 15 adolescents with DS were recruited.Results: An optimal grip span was identified for the dominant hand in adolescents with DS. The equation relating grip span as a function of dominant hand span in this group is formulated as follows: y = 0.342x - 1.161 cm (r = 0.63, p < 0.05). In the case of non-dominant hand, a tendency towards a linear association (p = 0.058) was found; the equation is formulated as follows: y = 0,210x + 1.324 cm.Conclusion: It is important to standardize the procedure and increase reliability when measuring hand grip strength in DS population. The values stated in this study are recommended to assess hand grip strength in adolescents with Down syndrome.

Vitamin D (vitD) deficiency is a worldwide problem. Therefore, the main aims of this study were to compare 25-hydroxivitamin D levels (25(OH)D) in adolescents with and without Down syndrome (DS) and to study the relationship between 25(OH)D and bone. Eleven adolescents with DS (6 females) aged 15.5 ± 2.8 years and sixteen healthy controls (non-DS) (6 females) aged 14.3 ± 2.2 years were evaluated by bone imaging techniques. Blood samples were collected to determine vitD levels. Independent t-tests and analyses of covariance controlling for age, height, sex, sexual maturation, calcium intake and body mass index were performed to evaluate differences in 25(OH)D levels between groups. Pearson’s correlation test and multiple linear regression analyses were performed to examine the association between 25(OH)D and bone mass. Adolescents with DS had lower 25(OH)D (22.8 ± 8.0 vs. 36.0 ± 6.5 ng/ml) than non-DS (d = 1.81; p < 0.05). Only 18% of participants with DS reached the recommended level of 30 ng/ml of 25(OH)D. No significant group interactions were found for any bone variable (all p > 0.05) but linear regression analyses suggested that 25(OH)D influenced positively femoral neck bone mineral density (β = 0.477, p = 0.038) and content at the 4% of the length of the tibia (β = 0.453, p = 0.008) in the non-DS and cortical volumetric bone mineral density at the 38% (β = 0.841, p = 0.034) in the DS. Adolescents with DS had lower levels of 25(OH)D and higher prevalence of vitD deficiency compared with non-DS. Associations between 25(OH)D and bone parameters were not observed for adolescents with DS but medium and positive correlations were observed in the non-DS group.

Many jumping interventions have been performed in children and adolescents in order to improve bone-related variables and thus, ensure a healthy bone development during these periods and later in life. This systematic review aims to summarize and update present knowledge regarding the effects that jumping interventions may have on bone mass, structure and metabolism in order to ascertain the efficacy and durability (duration of the effects caused by the intervention) of the interventions. Identification of studies was performed by searching in the database MEDLINE/PubMed and SportDiscus. Additional studies were identified by contacting clinical experts and searching bibliographies and abstracts. Search terms included "bone and bones", "jump*", "weight-bearing", "resistance training" and "school intervention". The search was conducted up to October 2014. Only studies that had performed a specific jumping intervention in under 18-year olds and had measured bone mass were included. Independent extraction of articles was done by 2 authors using predefined data fields. A total of 26 studies were included in this review. Twenty-four studies found positive results as subjects included in the intervention groups showed higher bone mineral density, bone mineral content and bone structure improvements than controls. Only two studies found no effects on bone mass after a 10-week and 9-month intervention. Moreover, those studies that evaluated the durability of the effects found that some of the increases in the intervention groups were maintained after several years. Jumping interventions during childhood and adolescence improve bone mineral content, density and structural properties without side effects. These type of interventions should be therefore implemented when possible in order to increase bone mass in early stages of life, which may have a direct preventive effect on bone diseases like osteoporosis later in life.

Background:Low bone mineral density (BMD) has been frequently described in subjects with Down syndrome (DS). Reduced physical activity (PA) levels may contribute to low BMD in this population. The objective of the study was to investigate whether PA levels were related to the femoral neck bone mass distribution in a sample of 14 males and 12 females with DS aged 12–18 years.Methods:BMD was evaluated by dual energy X-ray absorptiometry (DXA) at the integral, superolateral and inferomedial femoral neck regions and PA levels were assessed by accelerometry. The BMDs between the sexes and PA groups (below and above the 50th percentile of the total PA) were compared using independent t-tests and analyses of covariance (ANCOVAs) controlling for age, height and body weight.Results:No differences were found between the BMDs of males and females in any femoral neck region (p>0.05). Females with higher PA levels demonstrated increased integral (0.774 g/cmConclusions:This investigation shows that females accumulating more total PA presented increased BMDs at the integral and superolateral femoral neck regions (14.1% and 17.0%, respectively) when compared to their less active peers. These data highlight the importance of PA in females with DS to counteract their low bone mass and to improve their bone health.

Adolescents with Down syndrome (DS) have a unique morphology and body shape, and this needs to be taken into account when assessing body fat percentage (BF%). To develop a predictive equation from anthropometric variables (skinfolds) for estimating BF% in adolescents with DS. Twenty-three adolescents with DS (7 girls, 16 boys) participated in the study; seven skinfold measurements were taken (biceps, triceps, subscapular, supraspinale, abdominal, front thigh, and medial calf), circumferences and diameters were measured following ISAK recommendations. Total body volume (and then body density) was measured with air displacement plethysmography (ADP); BF% was then calculated. Correlation between anthropometry data and BF% by ADP, and stepwise regression analyses were applied to develop a specific prediction equation. All the skinfolds, BMI, hip, waist and thigh circumferences correlated with BF% and were included in the regression analysis; sex and triceps were added into the model (R2 = 0.89, p < 0.05). Therefore the proposed equation computed as follows: BF% = (0.97 TR) - (8.869·SEX) + 15.6 where TR is triceps skinfolds (mm) and SEX is equal to 0 for female and 1 for male. The proposed prediction equation is recommended for the assessment of BF% in adolescents with DS as it is the only one specifically developed and validated in this unique population. It is a cheap, reliable and accessible method that removes the need for use of expensive equipment.
