Effects of a group pelvic floor strengthening program on quality of life related to urinary incontinence in women over 60 years of age
Objective: To evaluate the effect of a group pelvic floor strengthening program on urinary incontinence-related quality of life in women over 60 years of age. Methodology: A single-group, quasi-experimental study was conducted with 28 women over 60 years of age with stress, urge, or mixed urinary incontinence. The program was carried out at a community day center over 14 weeks, with group sessions twice a week that included Kegel exercises, hypopressive exercises, core and lower limb strengthening, and education on the pelvic floor and self-care. The King’s Health Questionnaire (KHQ) and ICIQ-SF were administered before and after the intervention. Results: Participants were, on average, 70 years old, with a BMI close to 29, and most had a history of vaginal delivery; 54% presented with multimorbidity and 25% were taking polypharmacy. The ICIQ-SF showed a significant reduction in incontinence severity (from 9.71 to 6.03 points). Similarly, the KHQ showed significant improvements in several of its dimensions, reflecting a decrease in the impact of incontinence on quality of life. Overall, the results indicate that the intervention had positive effects on both the symptoms and the quality of life of the participants. Conclusion: A group intervention program for pelvic floor strengthening produces a significant improvement in the severity of urinary incontinence symptoms and in the quality of life of older women. Keywords: Urinary incontinence, pelvic floor, community program, quality of life, older adults.

The Effects of multicomponent training on psychological-behavioral symptoms and functionality in a person with alzheimer’s disease residing in an insular setting: single case study
Psychological and behavioral symptoms are common in patients diagnosed with dementia, especially Alzheimer's disease (AD), leading to functional impairments. Previous studies evaluating the effects of multicomponent training on these psychological and behavioral symptoms are inconsistent. Objective: To evaluate the effect of a multicomponent physical training program on the psychological and behavioral symptoms (PBS) and functional status of a person with Alzheimer's disease residing in an island region. Method: A single-case study (N=1) was conducted with an 84-year-old woman diagnosed with Alzheimer's disease and clinically significant psychological and behavioral symptoms. The intervention consisted of 30- to 45-minute sessions combining aerobic, muscle-strengthening, and balance exercises. The Neuropsychiatric Inventory (NPI) was used to assess symptoms, and the Activities of Daily Living Questionnaire (ADLQ) was used to assess functional status. Results: A reduction in caregiver distress and a decrease in caregiver burden were observed. The depression and anxiety domains showed the greatest reduction; irritability decreased, and functionality in Activities of Daily Living (ADLs) and functional capacity remained stable. Conclusion: Multicomponent physical training is a viable and effective non-pharmacological technique that can reduce caregiver distress and caregiver burden in people with Alzheimer's disease. This study presents a promising alternative for reducing caregiver distress and maintaining functional capacity.

Effects of Implementing a Training Program to Develop Cardiorespiratory and Muscular Endurance in Volunteers from the Second and Third Companies of the Villa Alegre Fire Department
Firefighting demands high levels of physical fitness, particularly cardiorespiratory and muscular endurance, due to the intense, intermittent, and demanding nature of emergencies. The objective of this study was to determine the impact of implementing a training program on cardiorespiratory and muscular endurance in volunteers from the Second and Third Companies of the Villa Alegre Fire Department. A pre-experimental, longitudinal, pre-post intervention study was conducted with a sample of 12 volunteer firefighters. The intervention consisted of a high-intensity circuit training (HICT) program applied over a period of 6 weeks. Cardiorespiratory and muscular endurance variables were evaluated using standardized functional tests before and after the program. Statistical analysis was performed using non-parametric tests for related samples, supplementing statistical significance with effect size calculations. The results showed significant improvements in most of the variables evaluated (p<0.05), with relevant increases observed in overall physical performance. Although the Sit-up Test did not reach statistical significance, it showed a positive trend in the median and a large effect size, suggesting clinically relevant functional adaptations. In conclusion, this study indicates that the implementation of the training program produced significant improvements in the cardiorespiratory and muscular endurance of the participating firefighters, evidenced by consistent increases in the applied functional tests. The improvements observed in the aerobic tests suggest an increase in the efficiency of the cardiorespiratory system, while the changes in the strength-endurance tests reflect relevant muscular adaptations.

Effect of Creatine Monohydrate on exercise-induced muscle damage markers and its effect on physical performance
Current updates in pain management ¿What new tools are available to us?
The contemporary approach to chronic pain has evolved from symptomatic models to an integrative view based on neurobiology, translational medicine, and therapeutic personalization. This review explores the most recent advances in pain management, including targeted pharmacological strategies, noninvasive neuromodulation, digital platforms, cognitive therapies, and genetic and neurophysiological biomarkers. Emerging interventions such as selective sodium channel blockers (e.g., VX-548), digital therapies such as immersive virtual reality and self-guided programs, as well as the use of cortical and spinal neuromodulation combined with computational analysis are highlighted. In addition, approaches that reconceptualize pain as a brain experience shaped by affective, cognitive and contextual factors, such as Pain Reprocessing Therapy and placebo with neurophysiological activation, are addressed. Integration between disciplines such as anesthesiology, neurology, psychiatry, genetics, and bioengineering has enabled the transition to precision, proactive, patient-centered pain medicine. This review highlights the value of translational research and the development of personalized tools to improve analgesic efficacy, reduce functional burden, and optimize quality of life for people with chronic pain.
Dual Tasks in Older Adults: Inte Dual-task training in older adults: a key strategy for preserving physical and cognitive function
Bilateral asymmetry and deficit in relation to horizontal force profiles in adolescents participating in a social sports program. A pilot cross-sectional study
The aim of this study was to examine the relationship between bilateral asymmetry (BA) and bilateral deficit (BLD) with the horizontal force–velocity profile (HFVP) in non-athletic adolescents participating in a social sports workshop in the city of Chillán. A quantitative approach was employed using a non-experimental, descriptive, and correlational cross-sectional design. The study population consisted of 11 nonathletic adolescents enrolled in a community-based football workshop in Chillán. BA was assessed through the calculation of the asymmetry index (AI), while BLD was quantified using the Bilateral Index (%BI). The HFVP was evaluated through video recordings, with data analysis conducted using the MySprint application. As the data followed a normal distribution, Pearson’s correlation test was applied to examine the relationships between BLD and BA with HFVP. Statistical analyses were performed using JASP software version 0.19.1.0 for Windows. The correlations between BA and HFVP variables (F0, VO, P_máx, RF_10m, RF peak) were not statistically significant, nor were the correlations between BLD and HFVP parameters (p < 0.05). In conclusion, neither bilateral asymmetry nor bilateral deficit were correlated with horizontal force–velocity profile parameters in untrained adolescents.
Exercise-Induced Anti-inflammatory Metabolism Benefits Against Chronic Non-Communicable Diseases, Overweight and Obesity. A Literature Review
Obesity and overweight are a worldwide problem due to their high prevalence that has increased in recent years and their close relationship with the appearance and development of chronic non-communicable diseases, together with the direct decrease in quality of life and increased mortality from all causes. Adipose tissue has been considered an endocrine organ capable of secreting adipokines involved in the regulation of systemic metabolism, however, when there is adipocyte hypertrophy caused by overweight, a chronic systemic proinflammatory state is generated, associated with many metabolic alterations, such as deregulation of the immune system, glucose metabolism and nitric oxide synthesis at the arterial level. Physical exercise has been proposed as a safe and effective tool for the prevention and treatment of various chronic pathologies, due to its high capacity to secrete myokines or exercises that have a positive impact on health, attributing a great systemic anti-inflammatory capacity.

Objective: To analyze the effects of the ATR training periodization method (accumulation, transformation, realization) on the physical form of university athletes, from the physical preparation and initial post-pandemic competitive period to a second continuous training process under normal sanitary conditions.Methodology: Pre-experimental, longitudinal, and comparative study of related samples. The sample consisted of 16 subjects aged 18 to 25, who were in an inactive training state before the intervention.Results: Between mesocycle 1 and mesocycle 2 of performance, athletes’ body composition improved significantly (p = 0.000809 and p = 0.000027). Strength training in power exercises, particularly the Clean and Jerk variants, showed significant improvement in both mesocycles (p = 0.000000). In the performance phase, pitchers exhibited significant progress between the two mesocycles (p = 0.000000). Regarding performance variables in competition, throwers increased their throwing distance, while sprinters and distance runners reduced their race times. Conclusion: The ATR periodization method proved to be an effective tool for structuring training loads across different periods. Additionally, its application resulted in significant and verifiable improvements in body composition and sports performance.
Anaerobic Performance and Athletic Talent in Elite Taekwondo Athletes
Introduction: It is paramount to analyze the profile and physiological needs of taekwondo athletes to optimize and enhance their sports performance. Objective: To determine the relationship between anaerobic performance variables in the rast test and athletic talent. Methodology: A quantitative research of quasi-experimental observational design with a descriptive-correlational approach was conducted. This study was carried out on Elite Taekwondo athletes affiliated with the United States Taekwondo National Governing Body (USAT) during the year 2023. Anaerobic performance was assessed using the Rast test, and athletic talent was considered as the position in the national ranking. Results: High negative relationships were identified in the variables of minimum power (-0.088) and fatigue index (-0.093), approaching significance (p<0.057) and (p<0.044) respectively. The other variables showed low to moderate negative correlations that were not significant. Additionally, a minimum power of 293.89 W, a maximum power of 390.37 W, and an average power of 346.16 W were observed. Furthermore, a relative power of 7.41 W adjusted for the athlete’s body mass was noted. In terms of anaerobic capacity, a value of 2052.23 W with a 25th percentile confidence interval (CI) of 1410.76 and a 75th percentile CI of 2849.17 was obtained. The fatigue index in the population was 4.39. Lastly, a median athletic talent score of 8.00 was found, indicating a high level of talent closely associated with top positions in the USA ranking. Conclusion: Greater anaerobic performance in terms of power and fatigue index is related to a better ranking position. These associations underscore the importance of anaerobic performance variables in competitive taekwondo performance and support the notion that superior power and fatigue resistance are linked to higher rankings.

Benefits of active pause in workplace and academic environments
Active pause is a widely recognized strategy in work and academic environments because of its positive impact on the health and well-being of individuals (1). This is a period of 10 to 15 minutes in the designated workplace or study place, for individual or collective change of activity. The active pause has shown (2) beneficial effects on the musculoskeletal and cardiovascular system, while minimizing negative impacts from work or academic activity. The active pause strategy has been found to be an effective measure for preventing muscle injury (3), reducing physical and psychological stress, and lowering ergonomic risk factors, especially in workers in sectors such as cleaning (4) During this short interval, simple exercises of stretching, mobilization and relaxation should be performed, with the aim of relieving the tension accumulated in the the muscles, improve blood circulation and promote proper posture.
Comparison of Pelvic Kinematic Behavior during Gait in Young people with and without Chronic Low Back Pain: A Kinematic Analysis with G-WALK
The aim of this study was to compare biomechanical adaptations during the gait in young people with and without Chronic Low Back Pain (CLBP). Thirty participants were recruited (15 people by group, with CLBP and control group). Using a G-Walk analysis system, the biomechanical variables analyzed included pelvic tilt, obliquity, and rotation, complemented with a Movement Symmetry Index during gait. The results show significant differences in the minimum right pelvic tilt (CLBP group = 16 (6) v. control group = 12 (7.1), p = 0.01) and in the ranges of right and left pelvic tilt, which were lower in the CLBP group (4.2 ± 1.1 v. 6.0 ± 1.8, p = 0.004; 4.4 ± 1.4 v. 6.0 ± 1.7, p = 0.01, respectively). Differences were also observed in the minimum right pelvic rotation and maximum left pelvic rotation (–2.8 (2.8) v. –5.2 (3.3), p = 0.011; 2.9 (2.3) v. 5.2 (3.1), p = 0.006, respectively) and in the range of right pelvic rotation (7.4 ± 2.7 v. 9.2 ± 2.7, p = 0.03). Additionally, the percentages of symmetry for pelvic obliquity and rotation were significantly lower in the CLBP group (obliquity in CLBP group: 92.7 ± 7.2% v. control group: 96.9 ± 2.3 %, p = 0.047; rotation in CLBP group: 90.9 ± 13.3 % v. control group: 97.0 ± 2.7%, p = 0.01). In conclusion, the highlights could suggest pelvic kinematics adaptations associated with CLBP.

Invasive mechanical ventilation in the patient with spinal cord trauma: A review of the literature
Spinal cord trauma (STT) represents a serious medical emergency that compromises neurological and respiratory function. Initial injuries trigger a series of pathophysiological processes, including inflammation and ischemia, which can aggravate neural damage. Respiratory dysfunction is common due to respiratory muscle involvement and loss of diaphragmatic function. Mechanical ventilation (MV) is essential to stabilize the patient and facilitate rehabilitation. However, MV in TRM faces unique challenges, such as prevention of muscle atrophy and management of complications such as ventilatorassociated pneumonia. Specific strategies, such as noninvasive ventilation and patientrespirator synchronization, are crucial to improve outcomes. Multidisciplinary management with neurosurgeons, intensivists and physiotherapists is critical to address the clinical and functional complexities of TRM and MV, ensuring comprehensive care and optimal recovery.

Low back pain covers a spectrum of different types of pain, such as nociceptive, neuropathic and non-specific pain, which frequently overlap. It is a very common symptom, which is today the main cause of disability throughout the world. Therapy usually begins with selfcare and pharmacotherapy in combination with non-pharmacological methods. Pilates has recently been proposed to reduce pain in these patients. The objective of this work is to carry out a systematic review on the effectiveness of Pilates to reduce pain in patients with low back pain. To do this, randomized controlled clinical trials were selected, carried out in humans, carried out in the last ten years. The main database used was PubMed, through the National Library of Medicine platform. The results showed that Pilates is effective in reducing pain in patients with low back pain. The total sample was 335 patients from six trials. The frequency of Pilates was 2 to 3 times per week, with a total duration between 6 and 24 weeks. The measuring instrument used to evaluate pain was the same in all studies: the visual analogue scale. Pilates was effective in reducing pain, improving function, quality of life, physical mobility, disability, flexibility, balance, static and dynamic resistance, and increasing lumbopelvic stabilization in patients with low back pain.
Effect of an interval training with rope in students of 7° and 8° basic of the city of Talca
The present study seeks to evaluate the effect of interval training carried out at the beginning of Physical Education classes on the improvement of aerobic resistance and physical activity levels in 7th and 8th grade students in the city of Talca. The study is experimental and involves 86 students aged 12 and 13, students from a municipal school in Talca, of which 34 are women and 52 are men. The intervention was carried out twice a week in eight classes of the subject. The group was divided into a control group (CG) n= 43 and an experimental group (GEXP) n43. The questionnaire on “physical activity levels” indicated that 39.4 % of the students in the sample did not do any type of physical activity, while 58.1 % did moderate physical activity, two to three days a week, while 39.4 % prefer vigorous activities two to three times a week. In relation to the results of the Ruffier-Dickson test, after one month, a Sig. p˂0.001 is achieved between the GEXP-GC group, on the other hand, in the initial and final intragroup results, in the experimental group, a Sig. p˂0.001 in a positive way while in the CG there is a Sig. P 0.004 in a negative way, since the students worsen their recovery from physical effort. The sample of 7th and 8th grade students maintains low levels of physical activity, the performance of moderate activities stands out, two to three times a week and a large percentage of students do not perform any activity that increases physical effort. The initial and final test results of the experimental group achieve significant results, that is, those who perform interval training with a rope at the beginning of physical education classes present better aerobic resistance than those students participating in a traditional class.

Use of Mobile Applications for the Practice of Physical Exercise in Technical-professional Students in the Area of Physical Activity and Sports in the Ñuble Region
Data were collected on the use of mobile applications (apps) in physical exercise, using qualitative, nominal and categorical variables to classify app use. The main objective of the study was to know the use of apps in physical exercise, the regularity with which students use them, the most used apps and the motivations that lead students to use them. With this study, relevant contributions were obtained to define strategies or procedures in the context of education, especially in the area of physical activity and health. The information collected is useful to understand the behavior of students in relation to mobile applications and could help to improve teaching and learning in these areas, since 85% of the participants recommend using mobile apps for physical exercise.
Applications of telerehabilitation in patients with Parkinson's. Systematic review.
Introduction: Parkinson’s is a chronic and progressive neurodegenerative disorder. Worldwide, disability from Parkinson’s is increasing faster than that from any other neurological disorder. Parkinson’s patients face numerous barriers to accessing face-toface rehabilitation services. For this reason, in recent years telerehabilitation has been proposed as a possible solution to this problem. The main objective of this work is to carry out a review of the literature on the applications of telerehabilitation in patients with Parkinson’s. Method: A review was carried out following the PRISMA regulations. The PubMed, Cinahl, PsycINFO, SPORTDiscus, Academic Search Complete, Lilacs, IBECS, CENTRAL, SciELO, and WOS databases were consulted. The Cochrane tool was used to assess the risk of bias and the quality of the evidence was assessed GRADE. Results: Telerehabilitation is effective in patients with Parkinson’s. The total sample was 256 patients. The number of telerehabilitation sessions ranged from 15 to 28 sessions, each lasting between 40 and 90 minutes. The total treatment lasted between 4 and 8 weeks and the frequency was between 1 and 3 times per week. Conclusions: Telerehabilitation is an effective alternative to clinical treatment to reduce postural instability, improve postural control, maintain speech, and improve strength. This therapy offers advantages over conventional face-to-face rehabilitation in clinic for patients with mobility difficulties.
