    Abstract: Small-sided games (SSGs) are frequently used in football training programs and their design has been analyzed in scientific literature. The aim of this study was to analyze differences in the mechanical and physiological demands of football SSGs with various configurations over an effective time of 6 min through the application of GPS/GNSS technology, heart rate monitoring, and player self-perceived effort. Thirty football players (21.59 ± 4.35 years, 72.74 ± 9.01 kg, and 178.16 ± 0.93 cm) completed 138 recordings during MD-3 sessions (matchday-3, 76 h pre-match) using Catapult OptimEye S5 devices, synchronized with the Polar system. The training structure was similar for all measurements. Analyses and comparisons were made using a total of ten training tasks and six study variables (dimensions, orientation, number of players, directionality, time distribution, and coaches’ feedback). SSGs played as 3 versus 3 showed higher mechanical responses with greater pitch sizes ( p  〈  0.001) and without the presence of goalkeepers ( p  〈  0.032). SSGs with a 6 versus 6 format showed higher velocities were attained when the pitch was long ( p = 0.021) and when the duration of the set was shorter (i.e., 2 min; p  〈  0.015). SSGs arranged as 3 versus 3, showed superior results for internal and external variables in comparison with 6 versus 6 ( p  〈  0.025). The application of new technology is necessary to understand internal and external workload responses to the multiple possible variations of the elements of SSGs. The understanding of these resources will contribute to the development of training tasks based on the complexity of football itself, considering the wide possibilities offered to coaches.

    Abstract: Objective: This study aimed to examine the effects of phenylcapsaicin (PC) supplementation on strength performance and neuromuscular activity in young trained male subjects. Materials and methods: A total of 25 trained subjects [full-squat (SQ) one repetition maximum (1RM) = 125.6 ± 21.0 kg] were enrolled in this randomized, triple-blinded, crossover, placebo-controlled trial. The subjects performed a first session and a post-24 h session for each condition. In the first session, the subjects ingested a high dose of PC (HD, 2.5 mg), a low dose (LD, 0.625 mg), or a placebo (PLA). Their performance in SQ was assessed under a 3% × 8 × 70% 1RM protocol in the first session. Their performances in countermovement jump (CMJ), SQ with 60% 1RM, and isometric squat were measured before and after the SQ protocol in both sessions. The neural activity of the vastus lateralis (VL) and vastus medialis (VM) was recorded via surface electromyography (EMG) and averaged in both sessions. Results: Significant differences between the conditions were reported for lifting velocity, velocity loss, and the 60% load in dynamic SQ ( p range = 0.02–0.04). Electrical changes were not identified for any outcome, although neural activity changed across time ( p range ≤0.001–0.006). A significant condition × time effect was observed in CMJ compared to PLA ( p ≤0.001) and LD ( p ≤0.001). Intra-set analyses revealed higher velocities in HD compared to those in LD ( p = 0.01) and PLA ( p range = 0.004–0.008). Conclusion: Therefore, PC may improve the strength performance and attenuate the mechanical fatigue induced by resistance training in SQ and CMJ exercises.

    Abstract: After the COVID-19 pandemic, society has become more aware of the importance of some basic hygienic habits to avoid exposure to pathogens transmitted via hands. Given that a high frequency of touching mucous membranes can lead to a high risk of infection, it is essential to establish strategies to reduce this behavior as a preventive measure against contagion. This risk can be extrapolated to a multitude of health scenarios and transmission of many infectious diseases. #RedPingüiNO was designed as an intervention to prevent the transmission of SARS-CoV-2 and other pathogens through the reduction of facial self-touches by thoughtfully engaging participants in a serious game. Objective Facial self-touches should be understood as behaviors of limited control and awareness, used to regulate situations of cognitive and emotional demands, or as part of nonverbal communication. The objective of this study was to ensure that participants become aware of and reduce these behaviors through a game of self-perception. Methods The quasi-experimental intervention was applied to 103 healthy university students selected by convenience sampling and put into practice for 2 weeks, with 1 control group (n=24, 23.3%) and 2 experimental groups (experimental group with no additional social reinforcement interventions: n=36, 35%; experimental group with additional social reinforcement interventions: n=43, 41.7%). The objective was to improve knowledge and perception and reduce facial self-touches to prevent exposure to pathogens transmitted via hands not only in health multihazard scenarios but also in ordinary circumstances. The ad hoc instrument used to analyze the experience consisted of 43 items and was valid and reliable for the purpose of this study. The items were divided into 5 blocks extracted from the theoretical framework: sociological issues (1-5); hygiene habits (6-13); risk awareness (14-19); strategies for not touching the face (20-26); and questions after the intervention (27-42), designed as a postintervention tool assessing the game experience. Validation of the content was achieved through assessment by 12 expert referees. External validation was performed using a test-retest procedure, and reliability was verified using the Spearman correlation. Results The results of the ad hoc questionnaire, which were analyzed using the Wilcoxon signed-rank test and McNemar index to identify significant differences between test and retest for a 95% CI, showed that facial self-touches were reduced (item 20, P 〈 .001; item 26, P=.04), and awareness of this spontaneous behavior and its triggers increased (item 15; P=.007). The results were reinforced by qualitative findings from the daily logs. Conclusions The intervention exhibited a greater effect from sharing the game, with interactions between people; however, in both cases, it was helpful in reducing facial self-touches. In summary, this game is suitable for reducing facial self-touches, and owing to its free availability and design, it can be adapted to various contexts.

    Abstract: Use of face masks in sport has been a particularly complex issue during the COVID-19 pandemic. Objectives: A systematic review to examine the physiological effects the different types of masks have on healthy adults when doing physical exercise. Data sources: PubMed, SPORTDiscus, Scopus, and Litcovid were searched up to March 20, 2021, following the PRISMA model. Articles published in the last 5 years with healthy adults. Study Selection: A total of 633 studies related to the use of masks during physical exercise were found, of which 8 articles met the criteria to be included. Study Design: Systematic review. Level of Evidence: Level 2. Data Extraction: The search process and the review of the articles were carried out by independent expert researchers. The risk of bias and the methodological quality of the different studies included in the systematic review were calculated following the Cochrane criteria using an adaptation for random cross-studies. Once the information was properly structured, the results were extracted, and the findings of the study analyzed. Results: There were significant changes in the following physiological variables when engaging in physical exercise using masks: 25% in the heart rate and dyspnea, 37.5% in the rating of perceived exertion, 50% in the pulmonary variables, and 37.5% in discomfort. The oxygen saturation, blood pressure, systolic blood pressure, diastolic blood pressure, and the concentration of blood lactate did not present any significant effect in this study. Conclusion: The usage of masks by a healthy adult population during the performance of physical exercise has shown minimal effects with regard to physiological, cardiorespiratory, and perceived responses. Some symptoms can be dyspnea, effort perceived, or discomfort, among others. These findings indicate that the use of masks is not harmful to individuals’ health. It does not present any significant detrimental effect on physical performance or risk to their well-being. However, further experiments are required to corroborate the findings of this review.

    Abstract: El calentamiento de competición es esencial en la activación y preparación del deportista. Un adecuado calentamiento para favorecer el rendimiento del deportista y reducir la incidencia de lesiones durante la competición en fútbol.  El objetivo principal de este estudio fue evaluar los calentamientos precompetitivos de diversas categorías del fútbol semiprofesional y amateur español, así como su relación con el rendimiento en la competición. Además, se analizó el efecto sobre el rendimiento de los protocolos de recalentamiento desarrollados durante el tiempo de descanso del partido. Estudio observacional desarrollado mediante análisis de variables GPS. Los resultados del estudio muestran los requerimientos condicionales de los calentamientos de competición en función del nivel de rendimiento y demarcación. Además, se puede observar la relación entre los requerimientos condicionales de los calentamientos y los primeros minutos de la competición. Por otro lado, se observa la incidencia del recalentamiento en los primeros minutos de la segunda parte del partido. Los calentamientos son un elemento esencial en el rendimiento y prevención de lesiones deportivas, sobre todo, durante los primeros minutos de la competición. El recalentamiento en la segunda parte del partido puede ser un recurso interesante si se realiza con tiempo suficiente y una adecuada metodología de intervención.

    Abstract: Soccer is a predominantly tactical sport and, therefore, tactical training has become the most widely used strategy to improve players' performance. The objective of the present study was to assess the workload of soccer-specific drills in professional players over a two-season period in an established context. GPS technology was used to record the data. One hundred and thirty-two (n = 132) soccer-specific drills were studied and grouped by categories. The individual demands of each task were related to the individual competitive profile of each player. The level of physical demand was significantly different in relation to the specific soccer drills analysed. Total distance covered, high-speed running, and the total number of high accelerations and decelerations were significantly higher in competition than in drills used for training sessions (p 〈 .001). The Large-Sided Games (LSG), Big-Position Games (BPG) and Position Games (PG) showed higher maximum running speed values than the rest of the exercises (p 〈 .01). The sum of high accelerations and decelerations values was greater in the Small-Sided Games (SSG) than in BPG (p 〈 .001), Small-Position Games (SPG) (p 〈 .001) and Physical-Technical Circuits (PTC) (p 〈 .001). Significant differences were observed in the exercises analysed according to the player’s position. The current findings provide a detailed description of conditional demands placed on soccer players in different soccer-specific drills during training sessions, in a professional soccer context and according to their playing position, which may be helpful in the development of individualized training programs in other contexts.
