KINEVOLEY SPA
Get PDFProyecto de intervención kinésica conducente al tÃtulo profesional de kinesiólogo.El voleibol es un deporte colectivo presente en Chile hace años, sin embargo, actualmente tiene nuevos referentes, quienes han potenciado la práctica de este esta disciplina. Cada jugador en cancha tiene una función y movimientos especÃficos a realizar, por lo que hay una amplia variedad de posibles lesiones. Si bien existen centros de kinesiologÃa deportivos, clÃnicas y hospitales que pueden atender una lesión deportiva, es importante el conocimiento de los patrones de movimiento de cada jugador para realizar las sesiones acordes a los objetivos y estilo de vida del usuario. KINEVOLEY SPA es una asociación de kinesiólogos enfocados en la prevención y rehabilitación de las lesiones más comunes del voleibol, desde el entendimiento de la biomecánica de sus movimientos y con el objetivo de optimizar el rendimiento deportivo
Effects of a specific injury prevention neuromuscular training program for young female dancers: A randomized-controlled trial
No full textTo assess the effects of a specific injury prevention neuromuscular training programme (IPP) on balance and lower-limb asymmetry in female competitive dancers (age 12-20 years; height 1.57 +/- 0.06 m; weight 24.27 +/- 2.79 kg) were randomly allocated to an active general control (GIPP, n = 7) and specific (SIPP n = 7) group. Both programmes were conducted for 6 weeks, with a frequency of three sessions per week. Dynamic balance and lower-limb asymmetry were assessed before and after the intervention. A greater improvement in right-leg total balance (86.6[84.0-90.5] vs 93.8[86.7-99.4];p = 0.035), left-leg total balance(87.8[81.0-89.1] vs 93.6[90.6-100.0];p = 0.013), left-leg anterior balance (71.9[69.1-72.2] vs 74.6[72.0-77.3];p = 0.041), left-leg posteromedial balance (80.5[72.9-83.3] vs 85.9[83.0-94.0];p = 0.048), and left-leg posterolateral balance (79.5[70.4-84.5] vs 85.0[80.0-88.5];p = 0.048) was observed in the SIPP group compared to the GIPP group. No other significant intra-group changes nor inter-group differences were noted. Therefore, compared to a GIPP, a SIPP induced greater improvements in lower-limb dynamic balance in female dancers, potentially leading to greater reduction in lower-limb injury risk
Differences Between The Perilaryngeal Pressure Pain Thresholds In Asymptomatic Women, Women With Bruxism, And Women With Odynophonia
No full textObjective: This study was aimed at comparing perilaryngeal pressure pain thresholds (PPT) among asymptomatic women, women with bruxism, and women with odynophonia. Design: Observational cross-sectional study. Methods: Eighty-four women whose age mean was 23.75 (SD, 3.02) years were grouped according to inclusion and exclusion criteria into a group of asymptomatic women (G1), another group of women with bruxism (G2), and another of women with odynophonia (G3). Palpation was used to identify regions of interest for this study, and an analog algometer was used to evaluate perilaryngeal PPT in the previously localized regions. Each PPT evaluation was done twice. Results: G1 PPT mean were between 1.35 (SD, 0.20) and 2.29 (SD, 0.28) kg/cm2, G2 PPT mean were found between 0.85 (SD, 0.12) and 1.78 (SD, 0.23) kg/cm2, and G3 PPT mean were located between 0.71 (SD, 0.11) and 1.45 (SD, 0.19) kg/cm2. Differences were observed between PPT in the three groups evaluated (P < 0.05). The intra-evaluator agreement between the evaluations performed fluctuated between 60.71% (κ = 0.51) and 92.86% (κ = 0.91). Conclusions: There are significant differences between the perilaryngeal PPT of asymptomatic women, women with bruxism, and women with odynophonia. Asymptomatic women had the highest PPT, while odynophonia sufferers had the lowest
Structural and functional brain changes in people with knee osteoarthritis: a scoping review
No full textBackground. Knee osteoarthritis is a highly prevalent disease worldwide that leads to functional disability and chronic pain. It has been shown that not only changes are generated at the joint level in these individuals, but also neuroplastic changes are produced in different brain areas, especially in those areas related to pain perception, therefore, the objective of this research was to identify and compare the structural and functional brain changes in knee OA versus healthy subjects. Methodology. Searches in MEDLINE (PubMed), EMBASE, WOS, CINAHL, SCOPUS, Health Source, and Epistemonikos databases were conducted to explore the available evidence on the structural and functional brain changes occurring in people with knee OA. Data were recorded on study characteristics, participant characteristics, and brain assessment techniques. The methodological quality of the studies was analysed with Newcastle Ottawa Scale. Results. Sixteen studies met the inclusion criteria. A decrease volume of the gray matter in the insular region, parietal lobe, cingulate cortex, hippocampus, visual cortex, temporal lobe, prefrontal cortex, and basal ganglia was found in people with knee OA. However, the opposite occurred in the frontal lobe, nucleus accumbens, amygdala region and somatosensory cortex, where an increase in the gray matter volume was evidenced. Moreover, a decreased connectivity to the frontal lobe from the insula, cingulate cortex, parietal, and temporal areas, and an increase in connectivity from the insula to the prefrontal cortex, subcallosal area, and temporal lobe was shown. Conclusion. All these findings are suggestive of neuroplastic changes affecting the pain matrix in people with knee OA
Ecological variation in invasive brown trout (Salmo trutta) within a remote coastal river catchment in northern Patagonia complicates estimates of invasion impact
No full textSalmonids were first introduced into the Chilean fresh waters in the 1880s, and c. 140 years later, they are ubiquitous across Chilean rivers, especially in the southern pristine fresh waters. This study examined the brown trout (Salmo trutta) and native taxa ecology in two adjacent but contrasting rivers of Chilean Patagonia. During spring 2016 and spring-fall 2017 we examined the variation in benthic macroinvertebrate and fish community composition and characterized fish size structure, stomach contents, and stable isotopes (delta 13C and delta 15N) to understand population structure, fish diet, and trophic interactions between S. trutta and native taxa. The native Galaxias maculatus (puye) dominated the fish community (74% of abundance). S. trutta was less abundant (16% of survey catch) but dominated the fish community (over 53%) in terms of biomass. S. trutta showed distinct diets (stomach content analysis) in the two rivers, and individuals from the larger river were notably more piscivorous, consuming native fish with a relatively small body size (<100-mm total length). Native fishes were isotopically distinct from S. trutta, which showed a wider isotopic niche in the smaller river, indicating that their trophic role was more variable than in the larger river (piscivorous). This study provides data from the unstudied pristine coastal rivers in Patagonia and reveals that interactions between native and introduced species can vary at very local spatial scales.This article was supported by FONDECYT 1161504 (G.C.) and projects from The Rufford Foundation 18782-1, ANID Millennium Science Initiative NCN2021_056: Millennium Nucleus of Austral Invasive Salmonids (INVASAL), project FONDECYT Iniciacion 11180914 (P.A.B.), along with project CHIC ANID/BASAL FB210018

Curricular reform of 11th and 12th grades in Chile
No full textLa entrada en vigencia de la Ley General de Educación en 2009 implicó la renovación curricular en todos los niveles del sistema escolar chileno, dejando para el final 3° y 4° medio. El presente trabajo describe este proceso de construcción curricular, desarrollado entre 2015 y 2019, a cargo del Ministerio de Educación y el Consejo Nacional de Educación. Para ello se analiza cada etapa a partir de material documental y actas de sesiones. El proceso de construcción desembocó en un currÃculum organizado en un Plan Común de Formación General, distribuido en asignaturas obligatorias y electivas, y un plan de Formación Diferenciada HC, TP y ArtÃstica, favoreciendo la electividad y flexibilidad. Entre otros, se concluye en el origen abierto y participativo de la construcción curricular, sin embargo, con el avance de las iteraciones Ministerio-Consejo, su impacto perdiendo peso a favor de las opiniones técnicas de consejeros, evaluadores y expertos
Cardiopulmonary- versus neuromuscular-based high-intensity interval training during a pre-season in youth female basketball players
No full textPurpose. This study compares the effects of 6 weeks of pre-season cardiopulmonary- vs. neuromuscular-based high-intensity interval training (HIIT) in female basketball players’ physical fitness. Methods. Overall, 16 female regional-level U19 basketball players were randomly allocated to a cardiopulmonary-based HIIT (C-HIIT) group (n = 8; age: 17.9 ± 0.6 years; height: 175.4 ± 6.5 cm; body mass: 68.1 ± 7.2 kg) or a neuromuscular-based HIIT (N-HIIT) group (n= 8; age: 18.0 ± 0.4 years; height: 175.6 ± 3.6 cm; body mass: 69.8 ± 5.0 kg). At the PRE-, MID- (3 weeks), and POST-training time points, the participants performed a 30-15 Intermittent Fitness Test (30-15 IFT; aerobic performance) and a repeated sprint ability (RSA) test (6 × 15 + 15 m [with 180° change of direction] with 20-second passive recovery). Results. A 2 × 3 mixed model analysis of variance revealed that both training interventions improved (p 0.05) in RSA results. Conclusions. C-HIIT and N-HIIT improves aerobic performance in female basketball players. However, for improvements in RSA, other training drills (e.g., repeated sprint training) and tasks with a higher number of changes of direction may be investigated
Poly(ethylene imine)-chitosan carbon dots: study of its physical-chemical properties and biological in vitro performance
No full textCarbon dots (CDs) have been quickly extended for nanomedicine uses because of their multiple applications, such as bioimaging, sensors, and drug delivery. However, the interest in increasing their photoluminescence properties is not always accompanied by cytocompatibility. Thus, a knowledge gap exists regarding their interactions with biological systems linked to the selected formulations and synthesis methods. In this work, we have developed carbon dots (CDs) based on poly (ethylene imine) (PEI) and chitosan (CS) by using microwave irradiation, hydrothermal synthesis, and a combination of both, and further characterized them by physicochemical and biological means. Our results indicate that synthesized CDs have sizes between 1 and 5 nm, a high presence of amine groups on the surface, and increased positive ζ potential values. Further, it is established that the choice and use of different synthesis procedures can contribute to a different answer to the CDs regarding their optical and biological properties. In this regard, PEI-only CDs showed the longest photoluminescent emission lifetime, non-hemolytic activity, and high toxicity against fibroblast. On the other hand, CS-only CDs have higher PL emission, non-cytotoxicity associated with fibroblast, and high hemolytic activity. Interestingly, their combination using the proposed methodologies allow a synergic effect in their CDs properties. Therefore, this work contributes to developing and characterizing CD formulations based on PEI and CS and better understanding the CD's properties and biological interaction.11220120; 11170244 y 11180616 del Fondo Nacional de Desarrollo CientÃfico y Tecnológico
