- PublicationOpen AccessA 16-week intervention on mood and life quality in elderly: testing two exercise programs(Universidad de Murcia. Servicio de publicaciones, 2021) Oliveira, Bruno R. R.; Cavalcanti Matos, Isabelle; Neto, Geraldo Maranhão; Rodrigues, Filipe; Monteiro, Diogo; Lattari, Eduardo; Machado, SergioThe purpose was to examine the effects of strength training program (STP) and multi-component training program (MTP) on mood states in physically active elderly. Thirty Brazilian elderly (female=21; male=9) aged between 65 and 75 years (66.94.1) with BodyMass Index (BMI) ranging from 25.6 to 31.0 kg/m2 (28.31.2), were enrolled for research. The elderly were randomly assigned into two groups: Strength Training Program (STP; age=66.74.4 years, BMI=28.21.3 kg/m2) and Multi-Component Program (MTP; age=67.13.9years, BMI=28.51.0 kg/m2). STP group performed three 1-hour sessions per week, working at a range of 3 sets, 8-10 repetitions, and 2-minute recovery between sets and exercises. MTP group performed two different types of exercise sessions: a) 50 minutes of Zumba©, followed by 5-10 minutes of dynamic stretching exercises; b) 40 minutes of body-weight dynamic and static exercises, as well as agility and balance movements. The Profile of Mood States (POMS) was applied to assess mood at baseline and post-intervention. No significant interaction or main effect for group and time was showed for six factors of the POMS. However, the magnitude-based inference showed that MTP is likely beneficial to reduce fatigue. On the other hand, MTP is possibly harmful to increase confusion and to reduce vigor when compared to STP. In practical terms, we can conclude that older people physically active seems to attain an adaptation in mood responses minimizing the additional effects of STP and MTP.
- PublicationOpen AccessEffect of pause versus rebound techniques on neuromuscular and functional performance after a prolonged velocity-based training(Human Kinetics, 2021) Martínez Cava, Alejandro; Hernández Belmonte, Alejandro; Courel Ibáñez, Javier; Conesa Ros, Elena; Morán Navarro, Ricardo José; García Pallarés, Jesús; Actividad Física y DeportePurpose: A variation of the traditional squat (SQ) rebound technique (REBOUND) including a momentary pause ∼2 seconds (PAUSE) between eccentric and concentric phases has been proposed. Although there is a consensus about the lower acute effects on performance of this PAUSE variant compared with traditional REBOUND technique, no information exists about the differences in longitudinal adaptations of these SQ executions. Methods: A total of 26 men were randomly assigned into the PAUSE (n = 13) or REBOUND (n = 13) groups and completed a 10-week velocity-based training using the SQ exercise, only differing in the technique. Neuromuscular adaptations were assessed by the changes in the 1-repetition maximum strength and mean propulsive velocity achieved against the absolute loads (in kilograms) common to pretest and posttest. Functional performance was evaluated by the following tests: countermovement jump, Wingate, and sprint time at 0 to 10, 10 to 20, and 0 to 20 m. Results: Whereas both groups showed significant increases in most of the neuromuscular tests (P < .05), the PAUSE (effect size [ES] = 0.76-1.12) presented greater enhancements than REBOUND (ES = 0.45-0.92). Although not significant, improvements in Wingate and sprint time at 0 to 10 and 0 to 20 m were higher for PAUSE (ES = 0.31-0.46) compared with REBOUND (ES = 0.10-0.29). Conversely, changes on countermovement jump and sprint time at 10 to 20 m were superior for REBOUND (ES = 0.17-0.88) than for PAUSE (ES = 0.09-0.75). Conclusion: Imposing a pause between eccentric and concentric phases in the SQ exercise could be an interesting strategy to increase neuromuscular and functional adaptations in sport actions that mainly depend on concentric contractions. Moreover, sport abilities highly dependent on the stretch-shortening cycle could benefit from the REBOUND or a combination of the 2 techniques.
- PublicationOpen AccessEntrenamiento de fuerza en futbolistas jóvenes: hacia una óptima relación entre la magnitud de la carga y la mejora del rendimiento(Universidad de Murcia. Servicio de publicaciones, 2022) Magallanes, Adrián; Parodi, Andrés; Magallanes, Carlos; Gonzalez Ramírez, AndrésIn soccer, sprinting speed and vertical jump are critical skills to achieve high performance. Controversy exists about which type of training is most appropriate to improve these skills in youth players with no previous experience in programmed strength training. The aim of this study was to evaluate the efficacy and efficiency of a 16-week programme of resistance (weight) and plyometric training on sprinting and vertical and horizontal jumping in male youth soccer players. The study involved 18 soccer players, 14.1 ± 0.3 years old, with no previous experience in programmed strength training. They performed a combined cycle of resistance and plyometric training on different days, twice a week, respectively. Before and after the experimental intervention, the athletes were tested in countermovement vertical jump, bipodal horizontal jump, unipodal horizontal jump and 30 m linear sprint. After the intervention, significant improvements were observed in all the variables analyzed (p ≤ 0.05). Given that the relationship between the improvement in performance and the magnitude of the loads applied was shown to be superior to other similar interventions, it is possible to conclude that this type of training programme is both effective and efficient in the population studied.
- PublicationOpen AccessSeguridad y eficacia del Método Pilates sobre el dolor físico, funcional y musculoesquelético en mujeres mayores(Universidad de Murcia. Servicio de Publicaciones, 2023) Brito, Dejair Lopes Santos de; Brandão, Thiago dos Santos; Santos, Isabel da Silva dos; Ramalho, Rodrigo; Freitas, Víctor Hugo de; Castro, Marcela Rodrigues deEl Método Pilates (MP) se propone como una estrategia no farmacológica para el manejo del dolor. Sin embargo, se sabe poco sobre la seguridad del método aplicado a los ancianos. El objetivo fue identificar el impacto de la MP en mujeres ancianas sin quejas de dolor musculoesquelético severo general y específico, considerando el dolor musculoesquelético físico, funcional y crónico. 19 ancianas se sometieron a 24 semanas de intervención con MP. Medimos la percepción de funcionalidad, dolor general y segmentación respectivamente por tres subescalas del SF-36 (capacidad funcional, aspectos físicos y dolor) y el Cuestionario Nórdico Musculoesquelético (NMQ). Para SF-36 tuvimos: capacidad funcional χ 2 (2) = 1.529, p = 0.465, limitaciones por aspectos físicos χ 2 (2) = 1.960, p = 0.375 y dolor χ 2 (2) = 1.213, p = 0.545 , no se encontraron diferencias significativas para ninguna de las variables a lo largo del tiempo. En cuanto al NMQ, observamos una diferencia significativa solo para la cadera / muslo, disminuyendo las quejas de dolor, hormigueo y entumecimiento en Q2 en comparación con Q1 (p = 0.01) y aumentando en Q3 en comparación con Q2 (p = 0.03). Se sugiere que el MP es seguro y aplicable en este público, ya que presentó resultados estables y no agravó la condición de dolor (general y localizado).
- PublicationOpen AccessThe effects of plyometric and resistance training on linear sprinting speed and repeated sprinting ability of youth players in Ethiopia(Universidad de Murcia. Servicio de Publicaciones, 2025) Chekle, Belayneh; Sin departamento asociadoThe study investigated the effects of resistance training, plyometric training, and resistance and plyometric training combined on linear-speed and repeated sprinting ability (RSA) of youth soccer players. The authors used a randomized block design, randomly assigning thirty-six male soccer players (aged 18 ± 1.212 years, with a body weight of 57 ± 3.580 kg) to one of three groups: plyometric exercise, combined plyometric and resistance exercise, and resistance exercise. The authors analyzed each group's performance gains by comparing the pretest and post-test performance scores using paired sample t-test. All three training groups achieved significant performance gains in linear speed and repeated sprinting ability (RSA) (p<0.05). The plyometric and combined groups achieved higher linear-speed performance than the resistance training group (p<0.05). However, there was no significant difference among the three groups in repeated-sprinting-ability scores (p>0.05). In conclusion, plyometric and combined exercises are important training methods to impact speed for soccer players. Thus, when the focus is on soccer-specific linear speed and repeated sprinting ability, coaches and their training programs should emphasize methods that incorporate appropriate plyometrics and resistance training. This fitness-oriented training has to be considered in line with the technical and tactical trainings as they are helpful to get the most from the players’ technical-tactical qualities.
- PublicationOpen AccessWingate test, when time and overdue fatigue matter: validity and sensitivity of two time-shortened versions(MDPI, 2020-11-11) Hernández Belmonte, Alejandro; Buendía-Romero, Ángel; Courel Ibáñez, Javier; Mora-Rodríguez, Ricardo; García Pallarés, Jesús; Martínez Cava, Alejandro; Actividad Física y DeporteThis study aimed to analyze the validity and sensitivity of two time-shortened Wingate anaerobic tests (WAnTs), by means of three phases. In Phase A, 40 participants performed a traditional 30 s WAnT, whereas the first 15 s (WAnT15) and 20 s (WAnT20) were used to elaborate two predictive models. In Phase B, another 30 s WAnT was performed by 15 different volunteers to examine the error of these models (cross-validation). Finally, in Phase C, a 30 s WAnT was registered before and after a 10-week velocity-based training conducted by 22 different participants (training group, TRAIN = 11; control group that fully refrained from any type of training, CONTROL = 11). Power changes (in Watts, W) after this training intervention were used to interpret the sensitivity of the time-shortened WAnT. Adjusted coefficient of determination (R2) was reported for each regression model, whereas the cross-validation analysis included the smallest detectable change (SDC) and bias. Close relationships were found between the traditional 30 s WAnT and both the WAnT15 (R2 = 0.98) and WAnT20 (R2 = 0.99). Cross-validation analysis showed a lower error and bias for WAnT20 (SDC = 9.3 W, bias = −0.1 W) compared to WAnT15 (SDC = 22.2 W, bias = 1.8 W). Lastly, sensitivity to identify individual changes was higher for WAnT20 (TRAIN = 11/11 subjects, CONTROL = 9/11 subjects) than for WAnT15 (TRAIN = 4/11 subjects, CONTROL = 2/11 subjects). These findings suggest that the WAnT20 could become a valid and sensitive protocol to replace the traditional 30 s WAnT.
