  Background: This study examines the acute effects of neuromuscular electrical stimulation (NMES) application on peak power (PP) and mean propulsive power (MPP) during a weighted squat jump (SJ(Loaded)). Methods: Fourteen male students (age: 23.71 +/- 2.30 years; height: 173.71 +/- 6.89 cm; weight: 69.59 +/- 9.08 kg; body mass index (BMI): 26.87 +/- 3.49) from the Faculty of Sport Sciences participated voluntarily. PP and MPP values were measured during the SJ(Loaded) movement, performed with an external load of 40% body weight, using a computer-integrated linear velocity transducer system (T-Force Dynamic Measurement System Ergotech Consulting SL, Murcia, Spain). NMES was bilaterally applied to the musculus hamstring and musculus quadriceps femoris for 20 minutes. The Shapiro-Wilk test, skewness and kurtosis values assessed data normality. Results: Differences between pre- and post-test PP and MPP power performances were analyzed using Paired Samples t-tests. Cohen's d (ES: effect size) and 95% confidence intervals (CI) were also calculated to assess the pairwise comparisons' magnitude. According to the analysis results, statistically significant improvements were observed in both PP (t (13) = -2.612, p = 0.021, d: -0.69 (-1.27; -0.10, 95% CI)) and MPP (t (13) = -2.756, p = 0.016, d: -0.73 (-1.32; -0.13, 95% CI), moderate effect) values after the NMES application. Conclusions: NMES significantly enhances PP and MPP during loaded squat jumps, highlighting its potential as a supplementary training tool for improving explosive power. Future studies should explore its long-term effects across different sports and populations, such as female athletes or older adults, to optimize training protocols. Research on NMES intensities and frequencies may provide insights into optimal parameters for power development and neuromuscular adaptation.

  Meditative pathways to emotional intelligence in athletes: narrative review study

  Aouani, Hajer; Selmi, Walid; Hammami, Achraf; Ceylan, Halil Ibrahim; Hammami, Raouf; Bayrakdaroglu, Serdar; Bayrakdaroglu, Yesim; Uluç, Ender Ali; Raul-Ioan, Muntean; Uluç, Sinem

  Emotional intelligence, encompassing self-awareness, emotional regulation, empathy and social skills, holds pivotal importance in the pursuit of excellence for athletes. Meditation, represented by various forms such as mindfulness, loving-kindness, visualization, breath control and relaxation exercises, offers athletes a structured pathway to deepen self-awareness, enhance emotional regulation and foster empathy. In conclusion, meditation emerges not merely as a relaxation technique but as a transformative journey that empowers athletes to master their emotions, excel in sports, and enhance their overall well-being. This narrative literature review highlights the profound impact of meditation on athletes' emotional intelligence, encouraging further exploration in this evolving intersection of sports and mindfulness. In the demanding world of sports, emotional intelligence (EI) is a critical factor for athletes' success, encompassing self-regulation, empathy, communication and composure under pressure. Meditation, a transformative tool for deepening self-awareness, emotional regulation and mental resilience, has emerged as a promising avenue for cultivating EI in athletes. This narrative review synthesizes existing research and personal narratives to explore the interplay between meditation and EI in the context of sports. Evidence suggests that meditation can enhance EI through mindfulness, loving-kindness and visualization practices, promoting focus, stress management and emotional resilience. Integration of meditation into athletic training regimens offers athletes a competitive edge, sharpening their mental acuity and fostering supportive team dynamics. While the transformative potential of meditation for EI is substantiated by research, limitations such as the predominance of qualitative studies and case reports warrant further empirical investigations. Overall, this narrative review highlights the promising relationship between meditation, EI, and athletic performance, paving the way for future research and practical applications of mindfulness practices in the sports world.

  Effects of different rest intervals in high intensity interval training programs on VO2max, body composition, and isokinetic strength and power

  Kayhan, Recep Fatih; Bayrakdaroglu, Serdar; Ceylan, Halil Ibrahim; Eken, Ozgur; Bayrakdaroglu, Yesim; Badicu, Georgian; Al-Mhanna, Sameer Badri; Enoiu, Razvan-Sandu; Ardigo, Luca Paolo

  The aim of this study was to evaluate the effect of 8 weeks of short and long rest running-based high-intensity training (HIIT) on body composition, isokinetic strength, and maximal oxygen uptake (VO2max). Nineteen physically active men were recruited to voluntarily participate in the study. The participants were grouped using the closed-envelope randomized method as HIIT with a short rest (HIITS, n = 9; age: 19.60 +/- 1.34 years) and HIIT with a long rest (HIITL, n = 10; age: 19.77 +/- 0.97). Pre and post the 8-week running-based HIIT program, body mass index and body fat % were measured and all subjects performed isokinetic strength tests to determine their hamstring (H)/quadriceps (Q) peak torque ratio and the peak power and peak work for their H and Q muscles. The participants also underwent a graded exercise test to determine their VO2max. Statistical analysis performed with One-Way Variance Analysis and Bonferroni correction post hoc tests. As a result of the study, there were no significant differences between the pre- and post-training isokinetic strength parameters for the H and Q of HIITL and HIITS at velocities of 60 and 240(degrees)s(-1). The VO2max did not change for HIITS training but the VO2max increased (p < 0.05) for HIITL training. In conclusion, that HIITL and HIITS programs for 8 weeks did not change the relative and absolute strength, force production and the VO2max, but the VO2max increased (p < 0.05) for HIITL training.

  Functional outcome and single hop test results of ACL reconstruction in athletes at a follow-up of 6 and 12 months: modified all-inside versus conventional hamstring autograft

  Yoldaş, Burak; Yılmaz, Ali Kerim; Yılmaz, Coşkun; Akdemir, Enes; Anıl, Berna; Benli, Merve Demir; Genç, Ahmet Serhat; Kehribar, Lokman

  Anterior cruciate ligament (ACL) tears are injuries with a high incidence in athletes, and ACL reconstruction (ACLR) is a surgical treatment orthopedists perform. This study aims to compare the 6 and 12 months post-op results of single leg hop tests (SLHT) performed in multidirectional conventional semitendinosus/gracilis (ST/G) and modified all inside (MAI) ACLR techniques on both sides and the limb symmetry indexes (LSI) of both techniques. This study evaluated a retrospective cohort of 50 male athletes who applied MAI (n = 23) and traditional ACLR ST/G (n = 27) techniques. Functional knee strength of the participants on both sides was measured with different SLHTs at 6 and 12 months postoperatively. The SLHT included medial side (MSTH), triple hop (TH), medial rotation (90◦) (MRH), crossover triple (CH) ve the single hop (SH) hop for distance. Both ACLR techniques showed significant improvement in mean Tegner, International Knee Documentation Committee (IKDC) and Lysholm scores preoperatively and at 6 and 12 months postoperatively (p < 0.05). For MAI and ST/G techniques, there was no significant difference in the results of SLHTs at 6 and 12 months for both the operated and non-operated sides (p < 0.05). Significance was found only in the MRH test of the non-operated side (p < 0.05). There was no significant difference in SLHT scores between the operated and non-operated sides at 6 and 12 months postoperatively (p > 0.05). There was no difference in LSI scores between techniques (p < 0.05). Our study revealed similar LSI rates in ST/G and MAI techniques at 6 and 12 months, suggesting that MAI technique can be used as a functional ACLR technique for athletes.
