“…Participants were instructed to squat to a 90° angle, pause for 1-2 seconds, and then jump vertically without leaning forward with hands on hips. Bending knees at 90°, separating hands from hips during the jump, or bending knees during flight phase were considered incorrect movements [19].…”

Background and Study Aim. The aim of this study was to examine the effect of a 6-week plyometric training program on agility, vertical jump, squat jump, and speed performance in soccer players. Material and Methods. A total of 26 male soccer players actively playing for Ankara Batıkent Kartal Sports Club participated in the study as volunteers. The players had an average age of 15.04 ± 0.16 years, an average height of 172.48 ± 5.14 cm, and an average body weight of 62.65 ± 0.38 kg. Data on the players' gender, age, body weight (kg), height (cm), body mass index (BMI), agility, vertical jump (cm), squat jump, and 30 m speed were obtained. Statistical analysis was performed using SPSS 25 software. The normality of the data was examined using the Shapiro-Wilk test. Paired samples t-test was used to determine within-group differences, and independent samples t-test was used to determine differences between groups. A statistical significance level of p < 0.05 was considered for all evaluations. Results. The plyometric training program was effective in improving agility, vertical jump, squat jump, and speed performance in the experimental group. There was a significant difference in agility and 30 m speed values in the pre-test and post-test evaluations of the Control group, but no difference was observed in vertical jump and squat jump values. Additionally, in the pre-test and post-test comparison between the experimental and control groups, a significant difference was observed in agility, vertical jump, and squat jump values. However, no significant difference was found in 30 m speed values. Conclusions. That plyometric training program is effective in improving agility, vertical jump, squat jump, and 30 m speed values.

“…In order to perform CMJ and SJ tests and obtain the jump height in centimetres, an Optojump TX10 (Bolzano, Italy) was used. This system, consisting of a transmitting and a receiving bar, allows measuring flight and contact times (Santos-Lozano et al, 2014), is portable, and adjustable to limited spaces (Gherghel et al, 2021).…”

The aim of this study was to determine the influence of the menstrual cycle on the elasticity index in female soccer players. A quasi-experimental analysis was carried out with a time series design, with a sample of 14 female players between 16 and 23 years (18.50 ± 1.74) where during all the phases of a menstrual cycle they had to perform the Squat Jump and Counter Movement Jump tests in order to calculate the elasticity index. Descriptive, normality, sphericity test and a repeated measures ANOVA with a Bonferroni type Post-Hoc test were performed. The most relevant aspect was that there were significant differences in the elasticity index between the Follicular Phase and the Ovulatory Phase, obtaining higher percentages of elasticity index in this second phase, but there were no significant differences between the other phases. The results obtained determine that the elasticity index is higher in the Ovulatory Phase than in the rest of the phases and this could be mainly due to the oestrogen peak and that there are no significant differences in the Luteal Phase demonstrates the relevance of this hormone with respect to explosive strength and the elasticity index. This study will allow the use of strategies with the intention of being able to optimally place the loads during plyometric training in reference to the menstrual cycle. While menstrual discomfort is subjective, they should be taken into account. Conversely, the elasticity index provides a reliable objective data that assists in designing personalized training programs.

This study aimed to assess the accuracy, precision, and sensitivity of the Ergonauta contact plate in evaluating jump height performance in countermovement (CMJ) and squat jumps (SJ), compared to two previously validated devices (OptoJump and My Jump). Twenty-six young basketball players participated in the study. The participants positioned themselves on the Ergonauta contact plate along with the My Jump app and OptoJump optical measurement system. Three CMJs and SJs were performed, and jump height was analyzed. Intraclass correlation coefficient (ICC) and typical error (TE) were used as relative and absolute reliability indicators, respectively. The Bland-Altman plot was used to examine agreement between metrics (Ergonauta contact plate, My Jump app, and OptoJump) in CMJ and SJ, with significance set at p < 0.05. Results demonstrated excellent relative reliability for both protocols in the Ergonauta contact plate (ICC = 0.94–0.99, TE = 1.07–1.23). Bland-Altman plots showed good agreement for the Ergonauta contact plate (CMJ and SJ) and devices (close to 0). In conclusion, the Ergonauta contact plate proved reliable and valid for assessing jump height performance, particularly in measuring jump height and mean propulsive velocity metrics.
