Background: Prenatal depression is associated with an increased risk of physical, physiological, cardiovascular, and psychological diseases for mothers and future newborns. Prenatal depression and depressive symptoms could have negative effects on the cognitive, emotional, social, and behavioral development of children.Objective: This study aimed to examine the influence of exercise during pregnancy on the prevalence of prenatal depression and depressive symptoms in the scientific literature.Data Sources: A search was carried out examining different online databases up to November 2020.Methods of Study Selection: A systematic review with random effects meta-analysis was performed. Only randomized controlled trials published in English or Spanish with pregnant populations and interventions with exercise programs carried out during pregnancy were included. The scores obtained by the tools that measured the emotional state and depressive symptoms as well as the number and percentage of depressed women of the study groups were analyzed.Tabulation, Integration, and Results: We analyzed 15 studies and found a negative association between moderate exercise during pregnancy and prenatal depression (ES = −0.36, 95% CI = −0.58, −13, I2 = 80.2%, Pheterogeneity = 0.001). In addition, the studies also showed that women who were inactive during pregnancy had a 16% higher probability of suffering prenatal depression [RR = 0.84 (95% IC = 0.74, 0.96) I2 = 61.9%, Pheterogeneity = 0.010].Conclusion: Supervised exercise during pregnancy may be useful for the prevention and reduction of prenatal depression and depressive symptoms.Systematic Review Registration: Registered in PROSPERO (Registration No. CRD42020164819).

Basketball for athletes with intellectual impairment (II) requires the development of evidence-based eligibility systems to guarantee that only athletes with significant limitations performing basketball participate in these competitions. In addition, this is needed to re-include IIbasketball in the Paralympic program. To do this, it is required to investigate how II impacts on fundamental basketball activities. To address this need, the aim of this study was to compare ablebodied (AB) and II-players´ capacity to solve a game situation. A field test was designed ad hoc in which 38 elite II-players from France, Portugal, Australia and Japan who participated in the Global Games (2015) and 38 AB-basketball players competing in Spanish competitions, had to solve 8 standardized game situations. Results indicated that II-players spent significantly (p≤0.05) more time to decide (0.92±0.2s) than AB-players (0.63±0.1s) and to execute the solution (II: 3.01±0.4s; AB: 2.56±0.3s). Also, II-players made more rule infractions (II: 7.11±1.4; AB: 7.71±0.7), more feints (II: 1.37±1.4; AB: 0.3±0.6), more dribbles (II: 15.08±3.9; AB: 12.29±2.3) and they performed less successful solutions (II: 4.42±1.5; AB: 5.39±1.3). However, no differences were found in number of correct decisions made. Decision time, number of dribbles and situations in which they succeeded were the variables that best discriminated between II and AB-players. These results confirmed the negative influence of II on players´ capacity to solve a basketball game situation. The calculated discriminant function let us establish the minimum scores from this test that indicates significant limitations on the capacity to solve a game situation. These scores are applicable to determine eligibility criteria in IIbasketball worldwide. Keywords: Classification, eligibility systems, Paralympics, decision making.

The purpose of this study was to develop a methodology to accurately analyze sprint performance of elite wheelchair basketball (WB) players in their own training context using a laser system and to analyze the velocity curve performed by the players regarding their functional classification and their playing position. Twelve WB players, from the Spanish men's national team, took part in an oncourt 20-m-sprint test. BioLaserSport® was used to obtain time, mean velocities (Vm), maximum velocities (Vmax), and distances at 90%, 95%, and 98% of their Vmax. Vm and Vmax reached high values in Classes II and III and in the guard playing position. The protocol developed with the laser system makes it possible to obtain a precise velocity curve in short sprints and allows easy analysis of decisive kinematic performance variables in WB players, showing immediate feedback to coaches and players. The normalized data allow an interpretation of how much, where, and when Vmax occurs along the test.

Pacing places a high demand on intellectual functioning and has been found useful for classification of athletes with intellectual impairments (II). This may also be true in open-loop sports like basketball. The aim of the current study was to investigate the pacing behaviour of basketball players with and without II. Using time-motion analysis, the activity of elite basketball players with II (n=37) and amateur players without II (n=34) was coded into four movement categories over eight periods of each game: standing, walking, running and jumping. Following two-way ANOVA, an effect of group showed differences between groups in duration and frequency of the movement categories within each period of the games.Additionally, an effect of time suggested that players in both groups paced their performances. However, no interaction was found, indicating that pacing may not be different between groups. In conclusion, the results suggest that due to the dynamic nature of basketball, the included players paced more intuitively by responding to environmental cues and using less deliberate planning. The players with II demonstrated slower games, which may be due to an impaired ability to make quick moment-to-moment deliberate decisions. These skills should be further studied in the context of evidence-based classification.

The aim of the present study was to assess the effects of a 10 week shoulder home based exercise program (SHEP) on shoulder pain (SP) and range of motion (ROM) in a group of elite wheelchair basketball (WB) players. A convenience sample of elite WB players (n = 36, 15 males and 21 females), mean age of 26 years (SD 7.6, range 15–45)) were assigned to either an exercise or a control group, according to the use of the wheelchair during daily activities. The shoulder pain index for wheelchair basketball players (SPI-WB), functional tests and ROM were measured at baseline and after a 10 week intervention. In the analysis of the SPI-WB scores, for the exercise and control groups separately, there were no significant reductions of SPI-WB scores after intervention. Related to the analysis between groups after 10 weeks of intervention, there were no significant differences in changes between the exercise and control groups (Z = 0.840, p > 0.05, r = 0.743). In this regard, there was a significant change after the intervention for shoulder extension ROM (Z = 2.81, p ≤ 0.05, r = 0.249). Shoulder Pain did not increase along the 10 weeks of the SHEP development in WB players who reported SP before the intervention program. However, in those players who started the intervention without SP, as no increase in SP was observed and players were free of injury. An exercise program could be a tool to maintain shoulder health and prevent injuries in elite WB players.
