The Effect of a Novel Video Game on Young Soccer Players' Sports Performance and Attention: Randomized Controlled Trial.

Background: Currently, the fusion of technology and sports is inevitable. The integration of various systems and devices has brought about significant transformations in established sports practices, impacting not only the rules but also physiological, biomechanical, and even psychological aspects. Objective: The purpose of this study was to analyze the effect of an attention intervention through a video game on young soccer players. Methods: Twelve young male soccer players (age: mean 8.5, SD 1 years) were divided into 2 groups: a control group (CG; n=10) and an experimental group (EG; n=10). During the 6-week training program, the EG received attention training through a video game twice a week for 15 minutes per session. Pre- and postintervention measurements included a specific decision-making soccer test and interviews with coaching staff. Additionally, success in the video game, muscular activity, and sweat levels were monitored. Results: The EG demonstrated a significant improvement in video game success following the intervention program, as indicated by the achieved level (P<.001). However, no significant differences were found between groups regarding electromyographic (EMG) activity (P=.21) and sweating (P=.20). Prior to implementing the attention training program, both groups exhibited similar data for variables related to decision-making and execution mechanisms (≤10%). Only 2 decision-making variables exceeded 10% but remained below 15% (Shot_D=13.35%; Marking_with_Ball_D=-12.64%). Furthermore, changes in attacking action variables were more pronounced in execution-related variables, except for dribbling and fixing. Conversely, in defensive action variables, changes were greater in decision-related variables, except for marking with the ball and marking without the ball. Conclusions: Our findings reveal that incorporating a specific attentional video game into a soccer training program enhances decision-making compared to a program without the video game. Therefore, it is advisable for practitioners to consider using this tool due to its high efficiency in terms of economic and temporal costs, particularly in improving a key psychological variable.

Bodyweight and Combined Training Reduce Chronic Low-Grade Inflammation and Improve Functional Fitness of Postmenopausal Women.

Exercise is an important tool against the deleterious effects of aging. Among the possibilities of exercise, bodyweight training (BWT) has been highlighted in the last years as a safe option to improve the health of older people. We compared the effects of 24 weeks of BWT and combined training (CT) on low-grade systematic inflammation and functional fitness in postmenopausal women. For this, 40 women were allocated and submitted to CT (n = 20, 64.43 ± 3.13 years, 29.56 ± 4.80 kg/m²) and BWT (n = 20, 65.10 ± 4.86 years, 28.76 ± 4.26 kg/m²). We measured inflammation by the interleukin-6 (IL-6), interleukin-10 (IL-10), and tumor necrosis factor-α (TNF-α) assessments. For functional fitness, we used tests similar to activities of daily living. At the end of the 16 weeks, data from 24 women were analyzed, CT (n = 14) and BT (n = 10). Both groups reduced TNF-α and IL-6 levels, without differences in IL-10. Regarding functional fitness, both groups demonstrated improvements in all tests after 24 weeks, except for rise from prone position and the 400-meter walk test for CT. In summary, CT and BWT are effective in reducing the plasma concentration of pro-inflammatory cytokines and improving functional fitness in postmenopausal women.
