    Efecto de un programa de acondicionamiento físico supervisado virtualmente sobre la condición física y el estrés percibido en docentes universitarios durante el confinamiento por COVID-19
    (Universidad de Murcia, Servicio de Publicaciones, 2022) Manito Quintero, Alejandro; Barranco Ruiz, Yaira
    El objetivo de este estudio fue analizar el efecto de un programa de acondicionamiento físico supervisado virtualmente sobre la condición física y el estrés percibido en docentes universitarios durante la situación de confinamiento por COVID-19. Un total de 15 docentes universitarios participaron un programa de acondicionamiento físico virtual basado en nuevas tendencias fitness (4-semanas/2-días/semana/45-minutos/sesión) durante el confinamiento por COVID-19. La condición física percibida mediante la International-Fitness-Scale (IFiS) y el estrés percibido mediante el Perceived-Stress-Questionnaire (PSQ-30) fueronevaluados pre y post intervención. El programa de acondicionamiento físico virtual mejoró significativamente la percepción de la condición físicageneral (p=0,011) y de la fuerza muscular (p=0,024), y generó una disminución significativa de la percepción de estrés (p<0.001). Un programa de acondicionamiento físico supervisado virtualmente basado en la tendencia fitness “HIIT whole-body” podría seruna estrategia eficaz para garantizar niveles saludables de condición física y estrés en docentes universitarios durante situaciones de confinamiento.

    Effect of combined high-intensity interval training and inspiratory muscle training on pulmonary function and exercise capacity in COPD patients
    (Servicio de Publicaciones. Universidad de Murcia, 2025) Ahmed, Ahmed S.; Alrawaili, Saud M.; Ismail, Samah M.; Alahmadi, Fahad H.; Sin departamento asociado
    The aim of this study was to investigate the effect of combined high intensity interval training (HIIT) and inspiratory muscle training (IMT) on pulmonary function and exercise capacity in patients COPD. This randomized, controlled trial study involved 100 COPD patients (GOLD stages II and III) aged between 40 and 70 years. Subjects were randomly assigned to one of two groups. The study group (n=50) underwent 8 weeks combined HIIT and IMT. The HIIT protocol involved four intervals, each lasting 4 minutes, beginning at 70% of maximum power and building to a target intensity of at least 85% HRmax. The IMT sessions included 2-3 sets of 30 breaths (totaling 60-90 breaths per session), with a two-minute rest between sets, three days per week starting with 30% of PImax and reaching 60% of PImax. The control group (n=50) performed an 8-week program of therapeutic education and 30-min self-based cycling or walking. Pulmonary function tests, incremental cycle ergometer tests, 6 min walk tests and inspiratory muscle strength were performed, and dyspnea and Halth-Related Quality of Life (HRQoL) were assessed before and after the intervention period. Results indicated that combined HIIT and IMT significantly improved exercise capacity, respiratory muscle strength, dyspnea, and quality of life in patients with COPD (p<0.05). There were no significant changes in pulmonary functions (p>0.05). This study suggests that integrating HIIT with IMT can effectively enhance the overall prognosis of patients with COPD.

    Effectiveness of high-intensity interval training on cardiovascular rehabilitation: A systematic review
    (Servicio de Publicaciones. Universidad de Murcia, 2025) Fernández-Revelles, Andrés B.; Fernández-Ortega, Javier; Sin departamento asociado
    This systematic review evaluated the effectiveness of high-intensity interval training (HIIT) in cardiovascular rehabilitation, analyzing its impact on cardiorespiratory capacity and quality of life in patients with heart disease. Searches were conducted in PubMed and Web of Science up to 01/08/2024 using MeSH terms related to “heart disease” and “physical exercise” (“High-Intensity Interval Training” AND “Heart Diseases” OR “Heart Failure”). The results showed that HIIT significantly improves VO2max and cardiac function, outperforming moderate-intensity continuous training (MICT). Additionally, it enhances patients' autonomy and well-being without increasing adverse event risk. In conclusion, HIIT is established as a key strategy in cardiac rehabilitation, providing significant improvements in cardiorespiratory fitness and quality of life for patients with heart disease. Its implementation optimizes resources in rehabilitation programs, offering an efficient alternative to MICT. However, it is crucial to continue conducting long-term studies to validate its efficacy and safety across different populations and clinical settings.

    Effects of high-intensity interval training on hemoglobin levels and oxygen saturation in healthy males
    (Servicio de Publicaciones. Universidad de Murcia, 2025) Gandasari, Maharani Fatima; Andiana, Olivia; Ramdan, Pelana; Raja Azidin, Raja Mohammed Firhad Raja Azidin; Raharjo, Slamet; Sin departamento asociado
    The aim of the study was to examine the effects of high-intensity interval training (HIIT) with high-intensity continuous training (HICT) on increasing hemoglobin levels and oxygen saturation in healthy men. This study used a quasi-experiment with a pre-test-post-test group design. A total of 40 healthy male adolescents, aged 19-22 years, with a body mass index (BMI) of 20-24 kg/m2 and normal blood pressure, were recruited from university students and given HIIT and HICT intervention programs for 30 minutes. Hemoglobin levels were measured using Mission® Hemoglobin Test Strips, while oxygen saturation (SpO₂) and heart rate (HR) were measured using an Oxyone Pulse Oximeter. The mean pre-HIIT and HICT hemoglobin levels were 16.86 ± 1.39 vs 16.34 ± 1.28 g/dL (p = 0.221), and post-intervention were 18.36 ± 0.96 vs 15.41 ± 1.55 g/dL (p = 0.000). SpO₂ pre-values between HIIT and HICT were 96.75 ± 1.37 vs 96.45 ± 1.36 % (p = 0.491), and post-values were 97.85 ± 1.23 vs 96.15 ± 1.35 % (p = 0.000). HR pre-values between HIIT and HICT were 71.40 ± 7.03 vs 71.20 ± 7.98 bpm (p = 0.933), and post-values were 81.25 ± 11.79 vs 97.05 ± 5.54 bpm (p = 0.000). The study concluded that HIIT was effective in increasing hemoglobin and SpO2 levels as an indicator of cardiorespiratory fitness compared to HICT. Furthermore, HIIT was also found to be more effective at speeding up HR recovery.

    The effect of four-week high-intensity interval training on increasing physical fitness and specific speed in young Pencak Silat athletes
    (Universidad de Murcia. Servicio de Publicaciones, 2025) Subekti, Nur; Hidayatullah, Mohammad Furqon; Syaifullah, Rony; Setiyadi, Noor Alis; Warthadi, Anugrah Nur; Sin departamento asociado
    This study aimed to determine the effect of high-intensity interval training (HIIT) on increasing aerobic performance and speed, specifically for Pencak Silat athletes. Thirteen student-level Pencak Silat athletes were selected using consecutive sampling methods and then divided into two groups: the experimental group (EG, n = 7) and the control group (CG, n = 6). The HIIT protocol on EG consists of 2 minutes x 3 sets, with a 1-minute rest interval between sets to adapt to the motion demands during the match. Yo-Yo Intermittent Recovery Test Level 1 (YYIR1) was used to measure aerobic performance capacity (VO2max) and FST to measure total kicks between pre- and post-HIIT. The results of the study showed that there was an increase in VO2max on EG (44.861.90 vs. 48.422.67 mL/kg/min; p=0.000) and CG (42.431.85 vs. 44.022.18 mL/kg/min; p=0.020). The mean delta in VO2max increased between the two groups, with a significant difference (p ≤ 0.05), and the EG produced a larger effect size compared to the CG. For total kicks, there was a substantial increase between pre-post on EG (105.727.89 vs. 112.578.91 n; p=0.001), while CG did not show any significant difference (p ≥ 0.05). These findings prove that the Pencak Silat-specific HIIT protocol can improve aerobic performance and speed specifically for Pencak Silat athletes.
