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.
- MakaleAçık Erişim2025Exploring the acute recovery effects of dry cupping therapy and electrical stimulation on anaerobic performance metrics in active individuals: A quasi-experimental crossover study

Background:This quasi-experimental crossover study aimed to examine the acute effects of dry cupping therapy (DCT) and neuromuscular electrical stimulation (NMES) on fatigue and perceived exertion in anaerobic performance among physically active individuals.Methods:Twelve male participants (mean age: 24.1 +/- 2.37 years), all students from the Faculty of Sports Sciences, were recruited to participate voluntarily. Anaerobic performance parameters, including peak power, mean power (MP), and fatigue index (FI), were assessed using a Monark 839E cycling ergometer under 3 distinct conditions: NMES, DCT, and a control condition (no intervention), with each session separated by a 48-hour rest period. Perceived exertion was evaluated immediately following each test session using Borg's rate of perceived exertion (RPE) scale. Both NMES and DCT were administered bilaterally to the hamstring (m. hamstring) and quadriceps femoris (m. quadriceps femoris) muscles for 20 minutes before testing.Results:The results revealed no statistically significant differences in peak power and MP across the conditions. However, significant effects were identified for FI (F(2, 22) = 4.08, P = .031, eta p(2) = 0.27) and RPE (F(2, 22] = 8.88, P = .0015, eta p(2) = 0.45). Post hoc pairwise comparisons indicated that NMES significantly reduced FI compared to the control condition (P = .0311), with a small to medium effect size (Cohen's d = 0.44). In terms of RPE, DCT significantly lowered values compared to both the control (P = .0018) and NMES conditions (P = .0005), demonstrating medium (Cohen's d = 0.74) and small to medium (Cohen's d = 0.37) effect sizes, respectively.Conclusions:While NMES and DCT did not elicit acute improvements in peak or mean anaerobic power, both interventions effectively mitigated fatigue and reduced perceived exertion during maximal anaerobic exercise. These findings suggest that NMES and DCT may serve as valuable recovery modalities for mitigating fatigue in sports characterized by high anaerobic demands. Future research should investigate the chronic effects of these interventions and explore their utility among trained athletes to determine their broader applicability in enhancing athletic performance.
