    AbstractDuring a pandemic, there are other ways of living and inhabiting space in a time that accelerates in the work of doctors and governments, and slows down in the daily life of the population in general. Societies are mediated and what happens is known through the media. The global health catastrophe is an obligatory agenda and television is its ideal medium: image, movement, sound, the faces of the pandemic are on the screens moment after moment. The routines of journalistic work make it possible to work in extreme situations and the information on the facts is given as usual. Television coverage is strange, but it is legitimized because television always reaches places that audiences cannot access. Television news responds to spectacularization to explain a dense present of confinements, masks, recommendations, decrees, claims, dismissal operations, violent speeches and different ways of inhabiting places in a harsh articulation with politics. In this work, the television agenda on the pandemic and its effects are problematized from a territorial perspective of media discursivities. And because it is a real-time investigation, it reflects on how to deal with a problem of highseverity while it is happening.En época de pandemia, hay otros modos de vivir y de habitar el espacio en un tiempo que se acelera en la tarea de médicos y gobernantes, y se ralentiza en la cotidianeidad de la población en general. Las sociedades están mediatizadas, lo que ocurre se conoce por los medios. La catástrofe sanitaria global es agenda obligada y la televisión es su medio ideal: imagen, movimiento, sonido, los rostros de la pandemia están en las pantallas momento tras momento. Las rutinas propias del trabajo periodístico posibilitan el trabajo en situaciones límite, se apela a cubrir los hechos como es habitual. La cobertura televisiva resulta extraña, pero se legitima porque la televisión siempre llega a lugares a los que las audiencias no acceden. La noticia televisiva responde a la espectacularización para explicar un presente denso por confinamientos, mascarillas, recomendaciones, decretos, reclamos, operaciones destituyentes, discursos violentos y modos diferentes de habitar los lugares en una dura articulación con la política. En este trabajo, se problematiza la agenda televisiva sobre la pandemia y sus efectosdesde una perspectiva territorial de las discursividades mediáticas.Y porque es una investigación en tiempo real, se reflexiona sobre cómo encarar un problema de alta gravedad mientras está ocurriendo.AbstractDuring a pandemic, there are other ways of living and inhabiting space in a time that accelerates in the work of doctors and governments, and slows down in the daily life of the population in general.

    Strength and power asymmetries have been observed in different sports, including soccer. Such asymmetries, as well as the bilateral deficit (BLD), can be assessed during different tasks, static or dynamic, and with different methods and devices, in order to detect the possible different aspects, as well as the association with physical performance and injuries. The aim of this study was to investigate the association between muscle asymmetries and BLD during a countermovement jump (CMJ), and tensiomyography (TMG) parameters and asymmetries, in the lower limbs of male soccer players. A total of 23 male soccer players (18 ± 4 years) were recruited. Bilateral and unilateral CMJs were performed, and peak power (W) and height (cm) were obtained. TMG was performed on different muscles of the lower limbs, and lateral and functional symmetries were obtained. Playing position and history of injuries were collected. CMJ inter-limb symmetry was found to significantly correlate with biceps femoris (r = 0.574, p = 0.004) and soleus (r = 0.437, p = 0.037) lateral symmetry. Players in central roles presented significantly worse functional symmetry scores of the knee than defense players (−17.5%, 95% CI −31.2–−3.9; p = 0.10). Participants reporting a history of injury at the ankle were characterized by significantly lower functional symmetry in both the dominant (43%, 39.5–48.0 vs. 74.5%, 46.5–89.3, p = 0.019) and non-dominant (45%, 42.5–46.0 vs. 81.0%, 45.8–90.3, p = 0.024) ankle. Findings from this preliminary study suggest an association between lower-limb muscle asymmetries during a dynamic task, such as jumping, and muscle contractile properties evaluated with TMG; moreover, functional asymmetries may be present after ankle injuries. Future studies in larger samples should evaluate the presence of such asymmetries as predictors or characteristics of different muscular and joint injuries

    Purpose. Gymnastics is a sport characterized by acrobatic and postural strength exercises that require great trunk muscles activation and control. Males and females can be characterized by different morphological and neuromuscular characteristics of such muscles, and this might be of importance for training and injury prevention. The aim of this study was to measure different aspects of trunk flexors and extensors characteristics in a sample of young female and male gymnasts. Methods. Twenty-eight sub-elite adolescent female (n = 14, 16 y, 14-17) and male (n = 14, 17 y, 14-18) gymnasts participated in this cross-sectional study. Tensiomyography was used to assess muscle contractile properties of the rectus abdominis (m.RA) and erector spinae (m.ES), while muscle thickness was assessed for abdominal muscles and lumbar multifidus (m.LM) with ultrasound. Flexors, extensors, and lateral endurance tests were performed. Results. Females presented smaller m.ES radial displacement (p < 0.001, p & eta;(2) = 0.535), smaller internal oblique thickness (p < 0.001, p & eta;(2) = 0.543), and shorter lateral endurance (p = 0.002, p & eta;(2) = 0.302). A significant side x sex interaction was found for the external oblique thickness (p = 0.004, p & eta;(2) = 0.276). Conclusion. Present findings report sex-based differences in abdominal and lumbar muscles characteristics and support the development of different sex-based training and rehabilitation protocols in adolescent gymnasts

    Objective: The aim of this study was to assess differences between people with episodic migraine and healthy controls in some neurophysiological and clinical outcomes, which, in turn, may highlight the differences in sensory processing, especially in cortical excitability, pain processing, and executive function. Methods: A cross-sectional study was performed, including the following outcomes: pressure pain thresholds with algometry; resting motor threshold, short-interval intracortical inhibition, and intracortical facilitation with transcranial magnetic stimulation; and executive functions with the trail making test and the frontal assessment battery. Results: Thirty adults with migraine (36 ± 10 years) and 30 healthy controls (29 ± 14 years) were included in this study. Compared with the healthy controls, participants with migraine presented lower pressure pain thresholds values in all the assessed muscles (P < 0.001), lower resting motor threshold (-10.5% of the stimulator output, 95% CI: -16.8 to -4.2, P = 0.001, Cohen d = 0.869) and higher short-interval intracortical inhibition motor-evoked potential's amplitude at 3 ms (0.25, 95% CI: 0.05 to 0.46, P = 0.015, Cohen d = 0.662), and worse performances both in trail making test (7.1, 95% CI: 0.9 to 13.4, P = 0.027, Cohen d = 0.594) and frontal assessment battery (-1.1, 95% CI: -1.7 to -0.5, P = 0.001, Cohen d = 0.915). Conclusions: Participants with migraine presented significant differences in cortical excitability, executive functions, and pressure pain thresholds, compared with healthy controls

    Inertial sensors (IMUs) have been recently widely used in exercise and rehabilitation science as they can provide reliable quantitative measures of range of motion (RoM). Moreover, the pressure pain threshold (PPT) evaluation provides an objective measure of pain sensation in different body areas. The aim of this study was to evaluate the efficacy of physiotherapy treatment in people with adhesive capsulitis in terms of RoM and pain improvement measured by IMUs and the PPT. A combined prospective cohort/cross-sectional study was conducted. Nineteen individuals with adhesive capsulitis (10/19 females, 54 ± 8 years) and nineteen healthy controls (10/19 females, 51 ± 6 years) were evaluated for active glenohumeral joint RoM and PPT on shoulder body areas. Then, individuals with adhesive capsulitis were invited to 20 sessions of a physiotherapy protocol, and the assessments were repeated within 1 week from the last session. The range of motion in the flexion (p = 0.001) and abduction (p < 0.001) of the shoulder increased significantly after the physiotherapy protocol. Similarly, the PPT was found to increase significantly in all the assessed shoulder body areas, leading to no significant differences compared to the healthy controls. IMU and PPT assessments could be used to evaluate the efficacy of physical therapy in people with adhesive capsulitis

    BACKGROUND: Primary dysmenorrhea represents one of the most common causes of pelvic and low back pain. Pharmacological treatment can present some side effects, and non-pharmacological treatments should be considered to improve the symptoms of primary dysmenorrhea. The aim of this study was to evaluate the efficacy of manual therapy (MT), pelvic floor exercises (PFE), and their combination (MT + PFE) to improve clinical outcomes and pain sensitivity in women with primary dysmenorrhea. METHODS: A prospective observational study was conducted. Thirty females (age 25.0 ± 6.1 y) with history of primary dysmenorrhea participated to 8 sessions of 60 min of either MT, PFE or MT + PFE, twice per week. They participated to the different treatments according to the different services offered by the school of physiotherapy. A 0–10 numeric rating scale (NRS) was administered to assess subjective pain, while short-form 36 (SF-36) was used to evaluate quality of life. The pressure pain threshold (PPT) was assessed with a portable algometer on different pelvic and lumbar areas. RESULTS: Independently from the treatment, significant improvements were reported for general pain NRS (p < 0.001; pη2 = 0.511), as well as most the domains of the SF-36, although the general health domain did not reach statistical significance (p = 0.613; pη2 = 0.010). PPT revealed a general improvement in all tested body areas, although on the quadratus lumborum, the PFE treatment did not induce a significant improvement compared to the MT and MT + PFE protocols (p = 0.039). CONCLUSIONS: These findings highlight the importance of proposing physiotherapy treatments to females with primary dysmenorrhea to improve symptoms, with manual therapy combined with active pelvic floor exercise providing the best outcomes including an improvement of lumbar pain thresholds

    Inertial sensors-based assessment to detect hallmarks of chronic ankle instability during single-leg standing: Is the healthy limb “healthy”?

    Background Chronic ankle instability can be common in sportsmen and can increase the risk of damaging the articular surfaces and result in negative consequences to joint health. Balance assessment is often used to evaluate ankle instability characteristics and guide rehabilitation protocols. This study aims to investigate balance-related parameters in people with chronic ankle instability and healthy-matched controls, using inertial sensors. Methods Ten young adults with a history of multiple ankle sprains (30 y, 25–34, 5 females) and ten matched healthy controls (30 y, 23–39, 5 females) were invited to participate in the study. Inertial sensors were placed on the head of the astragalus and on the chest to collect kinematic parameters during a 20-s single-leg stance performed on the leg with ankle instability (and corresponding for the healthy controls) and on the contralateral leg, randomly. Outcomes were calculated with MATLAB and subsequently analyzed. Findings A significant group effect was found only for the inversion angle (F1,15 = 12.514, p = 0.003, pη2 = 0.455), consisting of individuals with ankle instability being characterized by higher inversion angles (4.999 degrees, 95% CI: 1.987–8.011, p = 0.003) without significant side differences. No significant side x group effects were found for the assessed parameters. Interpretation Results from this study suggest that young adults with chronic ankle instability might be characterized by worse single-stance control in terms of inversion angle, and such worse performance could also be found in the contralateral leg. As such, inertial sensors could be used to assess kinematic parameters during balance tasks in people with chronic ankle instability

    In the beer-making process, is the disposal of raw material used for the preparation of beer wort, known as bagasse malt or beer bagasse. The presence of fiber, protein residue and sugars, makes this bagasse with potential for use in products developed in baking, such as loaves of bread and biscuits, where the increase, especially in fiber, beneficial to the consumer from a nutritional point of view and functionality, reinforce the need to explore their technological potential in order to provide the consumer differentiated products, competitive market and special features enhancing health. To explore the possibility of using a residue rich in fiber, malt bagasse it, this study aimed to assess the technological potential of the use of malt bagasse as food, as well as the effects of the merger on the sensory and functional qualities the biscuit. For the manufacture of biscuits type cookie, first elaborated the malt bagasse flour. Cookies were designed to replacing wheat flour for malt bagasse flour. We were evaluated physicochemical composition (moisture, ash, proteins, carbohydrates, lipids and crude fiber), pH, acidity and activity of water. The sensory evaluation was performed with 30 panelists who evaluated the products in relation to appearance, flavor, odor, texture, using a hedonic scale of nine points. The potential consumers in the sensory analysis showed buying interest in the product. With the results obtained from the cookie and sensory analysis, expected recovery of the waste, increasing its value and bringing benefits to breweries industries and bakery

    Context. Shoulder muscles are active during front crawl swimming to provide propulsion and stabilize the glenohumeral and scapulothoracic joints. It has been proposed that fatigue might contribute to altered activation of these muscles and represent a risk factor for injuries. Tensiomyography (TMG) might represent a non-invasive tool to detect exercise-induced neuromuscular fatigue changes in contractile parameters of the skeletal muscles, and it has never been used in the shoulder muscles in swimmers. Objective. The aim of this study was to assess the effects of a fatiguing swimming protocol on shoulder muscles TMG parameters and isometric strength in competitive swimmers. Design. A cross-sectional study. Setting. A swimming pool facility. Patients or Other Participants. Sixteen young front crawl competitive swimmers were invited to participate in the study, and 14 of them (21 y, range 17-26, 11 males 3 females) completed all the assessments before and after a 30-min high-intensity swimming training. Main Outcome Measure(s). The main outcome included the TMG assessment which was performed on seven muscles of the shoulder according to front crawl biomechanics and applicability of the technique, in order to obtain data such as time to contraction and muscle belly radial displacement (Dm), whereas isometric strength was assessed with a digital dynamometer during shoulder flexion, extension, external rotation and internal rotation. Results. Fatigue induced a smaller Dm (-0.5 mm, 95% CI: -0.7 - -0.3, p< 0.001, pη2= 0.692), mostly observable in latissimus dorsi and pectoralis major muscles. Only shoulder extension showed a significant isometric strength reduction after the fatiguing protocol (-0.03 N/kg, 95% CI: -0.05 - -0.01, p= 0.045, pη2= 0.275). Conclusions. This study provides preliminary evidence for the usefulness of TMG to detect fatigue-induced changes in contractile properties of the shoulder muscles in swimmers, in particular the latissimus dorsi, pectoralis major and lower trapezius

    Geological record of tsunami inundations in Pantano Morghella (south-eastern Sicily) both from near and far-field sources

    Abstract. Analysis of tsunami deposits from the Pantano Morghella area provided geological evidence for two inundations occurred along the south-eastern Ionian coast of Sicily. Pantano Morghella is a large pond characterised by a fine-grained sedimentation indicating a low-energy depositional environment. Two anomalous yellow sandy layers found at different depths indicate the occurrence of high-energy marine inundations. We studied sedimentological and paleontological features of the anomalous deposits as well as their spatial distribution observing the following properties: different facies with respect to the local stratigraphic sequence; erosive bases, rip-up clasts and broken elements testifying violent deposition mechanisms; macro and micro fauna of marine environment; relatively constant thickness throughout most of the depositional zone with thinning at the distal end; large sand sheets that extend inland. These observations, jointly with their infrequency in the sedimentary record and the age indicating a fast deposition, provided strong evidence for tsunami inundations. Correlations between anomalous layers and historical tsunamis are supported by radiocarbon and OSL dating results. The younger deposit is likely due to the 1908 near-source tsunami, whereas the flooding of the oldest event is most likely associated with a far and large source, the Crete 365 AD earthquake
