RESUMEN
BACKGROUND AND OBJECTIVE: To revise and critically summarize the available scientific evidence regarding the effect of exercise on sleep quality in patients with chronic kidney disease (CKD). METHODS: A systematic review of randomized controlled trials (RCTs) and comparative studies was conducted, searching MEDLINE/PubMed, SPORTDiscus, and Scopus using keywords "Exercise", "Physical Activity", "Chronic Kidney Disease," and "Sleep". The methodological quality of included studies was assessed using the PEDRo and MINORS scales. RESULTS: A total of 8 RCTs and 3 comparative studies were included, showing a low (n = 1), fair (n = 7), and good (n = 3) methodological quality. Most of the studies included patients undergoing hemodialysis (HD) (n = 8). Self-reported sleep quality (n = 9), sleepiness (n = 2), and objective sleep status (n = 2) were the main outcomes analyzed. The most frequent exercise interventions included aerobic training (n = 7), resistance training (n = 2), or a combination of both (n = 4). Generally, exercise induced positive effects on the reported outcomes. Data synthesis indicated that participants who exercised obtained significant improvements on their self-reported sleep quality in comparison with those included in the control groups, with a mean difference in the Pittsburgh Sleep Quality Index of - 5.27 points (95% CI - 7.76, - 2.77; p < 0.001). CONCLUSION: Preliminary scientific evidence indicates that patients with CKD, especially those undergoing HD, report improvements in self-reported sleep quality after taking part in aerobic exercise programs, while combined training interventions yielded diverse findings. The effects of exercise on sleepiness and objective sleep status were backed by few studies with mixed results.

OBJECTIVE: To examine the joint associations between physical activity and abdominal obesity with the risk of cardiovascular disease (CVD) events. METHODS: We included 70 830 UK Biobank participants (mean age±SD=61.6 ± 7.9 years; 56.4% women) with physical activity measured by wrist-worn accelerometers and without major chronic diseases. Participants were jointly categorised into six groups based on their physical activity level (tertiles of total volume and specific intensity levels) and presence or absence of abdominal obesity based on measured waist circumference. Associations with incident CVD (fatal and non-fatal events) were determined using proportional subdistribution hazard models with multivariable adjustment. RESULTS: After excluding events during the first 2 years of follow-up, participants were followed for a median of 6.8 years, during which 2795 CVD events were recorded. Compared with the low abdominal adiposity and highest tertile of physical activity, abdominal obesity was associated with higher risk of incident CVD, especially in those with low levels of vigorous-intensity physical activity (HR 1.42, 95% CI 1.22 to 1.64). Approximately 500 min per week of moderate-to-vigorous intensity and approximately 30-35 min of vigorous-intensity physical activity offset the association of abdominal obesity and the risk of having a CVD event. CONCLUSION: Physical activity equivalent to approximately 30-35 min of vigorous intensity per week appears to offset the association between abdominal obesity and incident CVD. About 15 times more physical activity of at least moderate intensity is needed to achieve similar results.

INTRODUCTION AND HYPOTHESIS: Studies on the prevalence of urinary incontinence (UI) among CrossFit practitioners are on the rise. This systematic review with meta-analysis was aimed at determining the prevalence of UI among CrossFit practitioners. METHODS: A systematic review of the literature was performed by searching MEDLINE/PubMed, Scopus, and SPORTDiscus through January 2021. The search strategy included the keywords CrossFit, urine incontinence, exercise, high impact and pelvic floor dysfunction. The inclusion criterion was any study with a sample of CrossFit practitioners and results separated from the other fitness modalities analysed. The subjects were women with no restriction of age, parity, experience or frequency of training. Quality assessment of the studies included was conducted using the Oxford Centre of Evidence-Based Medicine scale and the Newcastle-Ottawa Scale (NOS) adapted for cross-sectional studies. RESULTS: Thirteen studies (6 comparative and 7 non-comparative) were included for the systematic review, all using a cross-sectional design. The level of evidence was 4, with their quality ranging from poor (n = 10) to fair (n = 3). A total of 4,823 women aged 18 to 71 were included, 91.0% participated in CrossFit, and 1,637 presented UI, which indicates a prevalence of 44.5%. Also, 55.3% and 40.7% presented mild or moderate UI respectively. Stress UI was the most common type reported (81.2%). CONCLUSIONS: The factors that increased the likelihood of UI were age, body mass index and parity. Exercises based on jumps were commonly associated with urine leakage. CrossFit practitioners presented higher UI than control groups.

This review aimed to systematically evaluate and meta-analyze the available data on the effects of Brain Gym (BG) on cognitive function in older people. Six electronic databases were searched systematically using: "Brain Gym" AND "elderly, "Brain Gym" AND "older people". The PEDro and MINORS scales were used to evaluate methodological quality. For the meta-analysis, inverse variance or generic inverse variance was used and heterogeneity was assessed with the Chi2 test and I2 test. Ten research studies with a high to low quality. Significant changes intra- and inter-group were observed for neurocognitive outcomes in the BG groups. Findings from the metaanalysis indicated changes in the BG groups, on cognitive function by means of the Mini-Mental State Examination, were not greater than those reported in the control/comparison groups. BG will not lead to improvements in cognitive function in people with and without cognitive impairment, supported by low to high evidence.

BACKGROUND: Adults with intellectual disabilities often experience mobility limitations. Baduanjin, a mindfulness-based exercise intervention, can exert positive effects on functional mobility and balance. This study examined the impact of Baduanjin on physical functioning and balance of adults with intellectual disabilities. METHOD: Twenty-nine adults with intellectual disabilities participated in the study. Eighteen received a Baduanjin intervention for 9-months; 11 participants did not receive any intervention (comparison group). Physical functioning and balance were assessed using the short physical performance battery (SPPB) and stabilometry. RESULTS: Participants in the Baduanjin group experienced significant changes in the SPPB walking test (p = .042), chair stand test (p = .015), and SPPB summary score (p = .010). No significant changes between groups were observed in any of the variables assessed at the end of the intervention. CONCLUSIONS: Baduanjin practice may cause significant, albeit small, improvements in physical functioning of adults with intellectual disabilities.

BACKGROUND: Studies suggest that physical exercise lead to improvements in the psychosocial dimension, associated comorbidities as well as to a higher quality of life (QoL) in people with epilepsy. However, there is a need to provide evidence-based guidelines for its prescription. Therefore, this review aimed to systematically evaluate and meta-analyze the available data on the potential effects of physical exercise training programs in people with epilepsy. METHODS: Four electronic databases (MEDLINE/PubMed, PEDro, SPORTDiscuss and Scopus) were searched systematically from their inception until April 2022 for randomized controlled trials (RCTs), comparative studies and non-controlled studies that provided information regarding the effects of physical exercise training programs on people with epilepsy. The studies' methodological quality assessment was performed using the PEDro, the MINORS and the Quality Assessment Tool for Before-After Studies with No Control Group scales. For the meta-analysis, inverse variance or generic inverse variance was use to report mean difference or standardized mean difference for continuous data and their 95% confidence intervals (CI). Heterogeneity was assessed with the Chi-squared test and I2 test. RESULTS: After removing duplicated studies, 82 results were retrieved by the literature search and 14 were eligible for full text search. Finally, 14 studies with a methodological quality ranging from good to low quality met the inclusion criteria. Totally, 331 people with epilepsy were evaluated. Significant changes between preand post-intervention results in the exercise intervention groups were observed for QoL, fitness level, psycho-affective and neurocognitive outcomes. Findings from the meta-analysis indicated that moderate exercise led to a non-significant decrease (p = 0.08, Chi-squared test) in seizure frequency (SMD 0.33 95% CI 0.04; 0.70), while a significant effect of exercise was observed on QoL with a mean improvement of 4.72 percentage points (95% CI 0.58; 8.86, p = 0.03). CONCLUSION: Improvements on QoL, fitness level, psycho-affective and neurocognitive outcomes can be achieved through exercise training in people with epilepsy. Altogether, the findings suggest that people with epilepsy can benefit from exercising.

Re-warm-up activities are recommended in team sports due to loss of muscle temperature during half-time. This study aimed to evaluate the effects of a half-time re-warm-up strategy on female basketball players. Ten players U14, separated into two teams of five players, performed either a passive rest condition or repeated sprints (5×14 m) plus 2 min of a shooting wheel (re-warm-up condition), during the half-time break (10 min) of a simulated basketball match, where only the first three quarters were played. The re-warm-up did not elicit significant effects on jump performance and locomotory responses during the match, except for the distance covered at a very light speed, which was significantly higher than in the passive rest condition (1767 ± 206 vs 1529 ± 142 m; p < 0.05). Mean heart rate (74 ± 4 vs 70 ± 5%) and rate of perceived exertion (4.5 ± 1.5 vs 3.1 ± 1.44 a.u.) were higher in the re-warm-up condition during half-time (p < 0.05). In conclusion, performing re-warm-up activities based on sprints could be a valuable strategy to avoid the reduction of sport performance during prolonged breaks, but given the limitations of the study, these relationships need to be further explored in official competitions.

We analyzed whether male Spanish elite soccer players live longer than the general population. Secondly, we compared their mortality with a cohort of soccer players who continued working as soccer elite coaches after retirement. Using age and calendar-date adjusted life tables, we analyzed the mortality hazard ratio of 1333 Spanish male players born before 1950, and who played in elite leagues from 1939, compared with the Spanish population. Using Cox proportional hazards model we compared their mortality with a cohort of 413 players who continued as coaches. Players showed significantly lower mortality than the general population, but this advantage decreased with advanced age, disappearing after 80 years. Coaches showed a similar pattern. Comparing players versus coaches, date of birth and years as professional were associated with survival, but debut age and player position were not. Unadjusted median survival time was 79.81 years (IQR 72.37-85.19) for players and 81.8 years (IQR 74.55-86.73) for coaches. Kaplan-Meier estimator adjusted for covariables showed no difference between cohorts (p=0.254). In conclusion, former Spanish male players showed lower mortality than the general population, but this effect disappeared after 80 years of age. Continuing their career as coaches after retirement from playing did not confer major benefits.

Background and objectives: Handball is a popular sport among women whose practice can lead to marked health benefits but could also show a high injury risk. There is a lack of research on intermediate level female players. We aimed to identify the prevalence of sport injuries in amateur and young intermediate level female handball players and the potential influence of the sport category. Materials and Methods: A group of cadets, juvenile and senior female players of three handball clubs participating in the Spanish regional league were followed throughout the 2018-2019 season. Information on injuries and exposure was collected via questionnaires. Results: Out of 114 players (34 seniors, 33 juvenile and 47 cadets), 77 of them sustained at least one injury. Most of the injuries were either moderate or severe, regardless of the category. A total of 7.93, 5.93 and 4.16 injuries per 1000 h of exposure were registered in the senior, juvenile and cadet categories respectively. The risk of sustaining an injury was 2.14 times higher for senior players Confidence Interval (CI 95%: 1.51-3.03) and 1.92 higher for juvenile players (CI 95%: 1.32-2.78) when compared with cadets. Conclusions: Senior and young female handball athletes playing at an amateur and intermediate level, are exposed to a substantial risk of sustaining a moderate or severe injury. The players' category does not seem to have a great impact on the injury rate and on the characteristics of the sport injuries registered.

To provide information regarding the anthropometric and fitness profile of young karatekas and to study its evolution with age. Data from top-level karatekas were included in the analysis: 97 athletes in the U14 category (12-13 years old), 238 in cadet (14-15 years old), 261 in junior (16-17 years old) and 177 in U21 (18-20 years old), which makes a total of 773 athlete data sets. Karatekas underwent anthropometric (weight, height, body mass index and body fat percentage) and fitness (sit and reach, 20-m shuttle run, standing long jump, overhead 3-kg ball throw, 10x5-m shuttle run, and plate-tapping) assessments during the training camps organized by the Spanish National Karate Federation between 1999 and 2016. Male karatekas were taller and heavier, and performed better than females in all the fitness dimensions assessed, except for flexibility and speed of upper limb movements. The obtained cardiovascular and lower-body muscular values indicated that karatekas in this study were placed between the 80th and the 90th percentile when compared with the general population. The results of the agility, coordination and speed of upper limb movements, and flexibility tests showed that the karatekas obtained much higher scores than those observed in age-matched populations. Young karatekas show a high fitness level in comparison with the general population, especially with regards to aerobic performance, lower-body muscular power and upper-limb movement speed. Reference values of anthropometric and fitness dimensions are provided in order to be used by coaches, conditioning trainers and sport scientists when testing young male and female karatekas.
RESUMEN
This study aimed to determine if stretching exercise can be implemented as an adequate control therapy in exercise randomized controlled trials aimed at improving physical fitness and physical function in older adults. Five electronic databases were systematically searched for randomized controlled trials focused in the physical fitness and function of older adults using stretching exercise as control group. The methodological quality was assessed and a meta-analysis was carried out. Sixteen studies were included, 13 in the meta-analysis. The methodological quality ranged from fair to good. The meta-analysis only in the controls resulted in significant improvements in different functional parameters related to walking, balance, knee flexion strength, or global physical function. The interventions, compared with the controls, significantly improved balance and knee strength parameters. Stretching exercise as control therapy in older people can lead to beneficial effects and could influence the interpretation of the effect size in the intervention groups.
RESUMEN
PURPOSE: This case study provides information regarding the motor development and health-related fitness level of a female with 47,XXX. The Movement Assessment Battery for Children-Second Edition (MABC-2) and the Test of Gross Motor Development-Second Edition (TGMD-2) batteries were used to assess motor competence and gross motor development, respectively. Cardiorespiratory, muscular fitness, and flexibility were assessed by means of field-based tests. Two groups of children developing typically were used for comparison purposes. SUMMARY OF KEY POINTS: Results from the MABC-2 indicated that the participant was placed in the 37th percentile, whereas the comparison group was placed in the 68th percentile. The participant scored above the 50th percentile in the TGMD-2 and showed lower fitness values than those in the comparison group. RECOMMENDATIONS FOR CLINICAL PRACTICE: Contrary to what is generally expected, supernumerary 47,XXX does not have to negatively impact motor competence, although a low health-related physical fitness can be present.

Nordic walking (NW) seems to be an interesting rehabilitation strategy for women with breast cancer (BC). No review article that has synthesised and summarised the existing scientific evidence about the effect of NW on BC survivors has been published so far. A systematic review was conducted aimed at identifying the characteristics and methodological quality of the studies that have analysed the effects of NW on women with BC. The critical appraisal of the randomised controlled trials (RCTs) was retrieved from the Physiotherapy Evidence Database (PEDro). The methodological quality of the uncontrolled studies was evaluated by means of the Quality Assessment Tool for Before-After Studies with No Control Group. Nine investigations (four RCTs and five quasi-experimental studies) were included in the final analysis. The RCTs showed a fair methodological quality, while the quasi-experimental studies obtained a score ranging from "fair" to "poor". Judging from the findings of the analysed studies, NW had a significant and positive impact on a number of BC symptoms, including lymphedema, physical fitness, disability and morbid perceptions. No adverse effects were reported. However, due to the methodological limitations observed, further research is needed to confirm such findings.

Pilates may be a beneficial method of exercise for people with Parkinson's disease (PD). However, no studies have critically reviewed the scientific evidence in this regard. The purpose of this study was to conduct a systematic review and meta-analysis on the effectiveness of Pilates as a rehabilitation strategy for PD. A systematic search of the electronic databases PubMed, PEDro, Scopus, and SPORTDiscus was conducted to identify studies related to the effect of Pilates on PD. The search timeframe ranged from the inception of each database to March 2019. The search resulted in the identification of four randomized controlled trials (RCTs) and four non-RCT studies. The methodological quality of the investigations ranged from poor to fair. The descriptive analysis of the eight investigations showed that Pilates resulted in beneficial effects on fitness, balance and functional autonomy. A subsequent meta-analysis on the four RCTs indicated that Pilates was more effective than traditional training programmes in improving lower limb function. Pilates can be safely prescribed for people with mild-to-moderate PD. Preliminary evidence indicates that its practice could have a positive impact on fitness, balance and physical function. Its benefits on lower-body function appear to be superior to those of other conventional exercises. Future randomized studies with greater samples are needed to confirm these observations.

Background and objectives: People with multiple sclerosis (MS) often experience limitations in joint range of motion, which is linked to spasticity and continued inactivity. Low flexibility levels in this population have been linked to postural problems and muscular pain. Therefore, the purpose of this study was to conduct a systematic review and a meta-analysis aimed at identifying the characteristics and methodological quality of investigations studying the effects of exercise interventions on the flexibility levels of people with MS. Materials and Methods: Three electronic databases (MEDLINE/PubMed, SPORTDiscus and Scopus) were systematically searched up to May 2019 for intervention studies focused on the effects of exercise on the flexibility levels of people with MS. A meta-analysis, including randomized controlled trials (RCT), which reported information regarding the effects of exercise on flexibility, was also conducted. The methodological quality of included studies was assessed using the Physiotherapy Evidence Database, and the Quality Assessment Tool for Before-After Studies, with no control group. The quality of the information reported, regarding the programs conducted, was assessed by means of the Consensus on Exercise Reporting Template (CERT) scale. Results: Seven studies, four RCTs and three uncontrolled investigations were finally selected. The methodological quality of the RCTs was considered "poor" in one study, and "good" and "excellent" in two studies and one investigation, respectively. The three uncontrolled studies showed a methodological quality between "fair" and "poor". Following the CERT scale, four studies were graded as "high" and three as "low". Findings from the meta-analysis indicated no significant effects on hamstring flexibility, or the range of motion in the hips, knees or ankles. Conclusions: There is preliminary evidence from individual studies which indicates that people with MS can improve their lower limb flexibility following participation in physical exercise programs, but the meta-analysis did not confirm these findings.

This study aimed at identifying the effects of self-paced cycling on the cognitive and functional status and fall risk on institutionalized older adults without cognitive impairment. A total of 39 individuals were randomly assigned to an exercise group or to a control group. The exercise group participants cycled at their self-selected intensity at least for 15 min daily during 15 months. The control group participants performed recreational activities. The Mini-Mental State Examination, Fuld object memory evaluation, and symbol digit modality test were used for cognitive assessments. The Katz index, the timed "Up & Go" test, and the World Health Organization questionnaire were used to assess functional independence, mobility, and fall risk. Significant improvements were observed in the exercise group for global cognition and attention, visual scanning, and processing speed. Long-term self-paced cycling training seems to have a protective effect on cognitive status and attention, visual scanning, and processing speed in older institutionalized individuals.

The aim of this study was to verify the effects of functional-task training on cognitive function, activities of daily living (ADL) performance, and functional fitness in community-dwelling older adults with diagnosis of Alzheimer's disease (AD). A total of 57 participants (22 functional-task training group [FTG], 21 social gathering group [SGG], 14 control group [CG]) were recruited. Participants in both intervention groups carried out three 1-hr sessions per week of a functional-task program and social gathering activities for 12 weeks. Significant improvements were observed in executive functions (TMT, t-test, p = .03) in the SGG and in upper limb strength (arm curl, t-test, p = .01) in the FTG. Functional-task training has no significant effect on cognitive function, ADL, and functional fitness among people with AD, although it may contribute to slowing down the process of deterioration this illness causes.

The effects of physical activity on brain function can be assessed through event-related potentials (P300) that reflect cortical activities related to cognitive functions. P300 latency represents the information processing time; longer latencies represent slower processing. P300 amplitude is associated with the attentional system and working memory, with higher amplitudes representing more preserved functions. This systematic review summarizes the literature concerning the effects of physical activity and exercise on P300 in the elderly. Databases, including Web of Science, Scopus, PsycINFO, MEDLINE/PubMed, and Biological Abstracts, were searched for articles up to November 2015. Articles were considered for inclusion if they were studies of the elderly, assessed P300, and evaluated the influence of physical activity on P300 or the effect of physical exercise training on P300. Of the 1227 articles found, 14 investigations matched the inclusion criteria. Nine analyzed the influence of physical activity on P300 in the elderly, and five examined the effects of physical exercise on P300 in the elderly. The obtained results showed that physically active elderly people have shortened P300 latency and higher amplitude. Physical exercise, especially those involving aerobic or resistance training, seems to have marked beneficial effects on P300 in the elderly. Evidence shows that physical activity and physical exercise positively influence cortical activities related to cognitive functions, as indicated by P300, in elderly people.

This study evaluates the impact of Brain Gym (BG) training in active older adults. Eighty-five participants were assigned to four training groups: BG (n = 18), BG plus water-based exercise (n = 18), land-based exercise (n = 30), and land plus water-based exercise (n = 19). The effects of the programs on the attention and memory functions were assessed by means of the symbol digit modality test. The two-min step and the eight-foot up-and-go tests were used to evaluate their impact on fitness level. No program had a significant influence on the participant's cognitive performance, while different effects on the sample' fitness levels were observed. These findings suggest that the effects of BG on the cognitive performance and fitness level of active older adults are similar to those obtained after the practice of a traditional exercise program. Whether BG is performed in isolation or combined with other exercise programs seems to have no influence on such effects.

This study is aimed at analyzing the reliability of 2 field-based cardiorespiratory fitness tests when applied to a sample specifically made up of preschool-aged children. A total of 97 preschoolers (mean age: 4.36 ± 0.4 years; 50.5% girls) performed Course-Navette and Mini-Cooper tests 3 times (familiarization test and retest). The scores obtained were compared with the results provided by the 3-minute shuttle run test, which is considered to be a reliable field-based test for preschoolers. The Mini-Cooper test showed a high reliability for children aged 4 (intraclass correlation coefficient [ICC]: 0.942; 95% confidence interval [CI]: 0.903-0.965) and 5 years old (ICC: 0.946; 95% CI: 0.893-0.973). The reliability of Course-Navette was also high for both 4-year-old (ICC: 0.909; 95% CI: 0.849-0.945) and 5-year-old children (ICC: 0.889; 95% CI: 0.780-0.944). The mean scores of the 3-minute shuttle run test did not show a significant correlation with the mean scores obtained in the Mini-Cooper test and in the Course-Navette test in the 4-year-old children. The results of this study suggest that Course-Navette and Mini-Cooper tests are reliable measures of cardiorespiratory fitness that can be used to assess health-related fitness in preschool children. Nevertheless, some considerations must be taken into account before administering them.
