Article Synopsis
- - Repeated-sprint ability is crucial for football performance, with hamstring injuries commonly occurring during sprints when players are fatigued.
- - A study with 14 semiprofessional soccer players implemented 8 weeks of repeated-sprint training (RST), which involved multiple sets of short sprints with brief recovery periods.
- - Results showed significant improvements in sprint times and kinematic patterns, indicating that RST enhances sprint performance and promotes safer running mechanics, especially when players are fatigued.
Article Synopsis
- Current strength assessment devices in handball may lack specificity and reliability, but functional electromechanical dynamometry offers a new method for accurate strength testing.
- A study involving 14 male handball players examined the reliability of three strength tests—unilateral pullover, standing lift, and step forward—using this advanced technology over three testing sessions.
- Results indicated high or acceptable reliability for force measurements, with only minor differences observed between the left and right sides, confirming the tests as viable for evaluating physical performance alongside regular training.
Article Synopsis
- The study assessed body composition, maturation, performance, and adherence to the Mediterranean diet among 36 professional beach handball players, divided into junior and senior categories.
- Senior players outperformed juniors in all performance measures, showing significant differences (p < 0.005).
- A moderate adherence to the Mediterranean diet was noted, with better diet adherence linked to improved performance results in tests like the CMJ and Abalakov.
Article Synopsis
- Basketball's dynamic nature complicates tactical analysis, particularly in the use of screens, which require high levels of preparation for effective performance.
- This study aims to differentiate player behaviors by gender using a robust observational tool and advanced data analysis methods, validating its effectiveness through various statistical measures.
- A total of 294 ball screen situations were analyzed from top-level men's and women's teams in Spain, revealing significant behavioral patterns that can inform training programs to enhance player performance.
Article Synopsis
- High-level basketball has become more competitive, making it crucial for teams to maximize scoring chances during games.
- This study evaluates the technical-tactical behaviors during transition plays in professional basketball in Spain, utilizing a validated observation tool with high reliability.
- Analysis of data from Unicaja de Málaga games reveals significant relationships between focused and related behaviors, which can inform tactical decisions and intervention strategies to enhance team performance.

The first objective of this research was to analyze the relationships between the sports psychological profile, competitive anxiety, mood and self-efficacy in beach handball players. The second objective was to determine the predictive capacity of the psychological profile on competitive anxiety, moods and self-efficacy, which was assessed by linear regression analysis. One hundred and eighty-one beach handball players participated in this research (age: = 25.

To do this, and distinguishing it by genre, an analysis of polar coordinates was realized using the assist and completion of this specific position as behavior criteria. A total of 24 sessions were observed with the HOISAN computer software, using an design tool.

For this reason, a polar coordinates analysis was carried out, by gender, using as focal behaviors the simple and double goal, and the loss of possession of the attacking team, which are considered decisive in assessing the success of the decisions at the end of the positional attack. These focal behaviors have been linked to criteria that characterize the attack situation such as the minute, the score, the numerical balance, the defensive system and the duration.
