A cortesía é unha competencia pragmática clave para o dominio dunha lingua e a súa adquisición é un proceso que comeza na primeira infancia pero que non se completa ata a adolescencia. Á súa vez, as peticións constitúen un dos actos de fala que máis requiren da cortesía, posto que supoñen unha ameaza para o destinatario, o que leva á necesidade de empregar mecanismos que atenúen esta ameaza, para así preservar as relacións sociais e o bo desenvolvemento do intercambio comunicativo. Neste traballo estúdase o proceso de adquisición das estratexias de cortesía nas peticións por parte dos nenos e nenas galegofalantes, dende os catro ata os doce anos. Para isto, pártese dun traballo de campo que permitiu crear un corpus dun total de 504 peticións formuladas por 21 informantes divididos en tres grupos de idade diferentes. Analízanse, a partir deste corpus, cales son as principais estratexias de cortesía empregadas, que variables parecen incidir no emprego dunhas ou doutras estratexias e en que medida inflúen certos factores como a idade e o sexo das persoas informantes.

Context: Hypopressive exercise (HE) has been used as an alternative lumbo-pelvic injury prevention program and claimed to be a means of respiratory and flexibility improvement. However, the possible effects of HE on athletic populations and physical performance remain unclear. Objective: Examine the effects of a HE program on posterior back chain kinematics, thoracic mobility, pulmonary function, and lower lumbar pain in female basketball players over an 8-week training period. Design: Prospective (1) baseline, (2) midpoint (4 wk), and (3) after 8 weeks. Setting: Sports field. Participants: A total of 17 professional female basketball players (mean age 20.7 y, SD: 3.50; body mass index, 21.71, SD: 1.69). Intervention: Participants performed 8 HE weekly sessions of 30 minutes. Main Outcome Measures: Back chain kinematics was assessed with the sit and reach and finger to floor test, and back pain was assessed through numerical rating scale. Respiratory parameters were assessed by spirometry and through thoracic mobility. Results: The analysis of variance revealed significant differences between the 3 measurement periods for thoracic mobility (P > .01); forced expiratory volume in the first second (P P > .01), peak expiratory flow (P = .01), and forced expiratory volume in the first 25 seconds (P = .04). Also, significant differences between weeks were found in levels of lumbar pain (P = .003) and the finger to floor test (P = .002). Conclusions: These preliminary findings suggest that a HE program can improve posterior back chain and chest wall kinematics as well as lower lumbar pain levels. However, no gains seem to be observed for the majority of pulmonary variables except for peak expiratory flow and forced expiratory volume in the first seconds.

Hypopressive exercise (HE) has been contraindicated for people with cardiovascular disease because it involves isometric postures performed with low-pulmonary volume breath-holds, which are thought to increase blood pressure. The objective of this study was to analyze the hemodynamic responses to HE performed in the seated posture on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) in normotensive females. Ten women (age = 31.2 ± 6.3 years) with previous experience in HE participated. Three sets of eight breathing cycles of HE breathing were completed. The HE breathing protocol consisted of three complete breathing cycles of controlled latero-costal inhalations and slow deep exhalations followed by a breath-hold and rib-cage expansion after every third exhalation. Measurements of SBP, DBP, MAP and HR were assessed at baseline, at the end of each set and at the end of minute 5, 10, 15 and 20 during the recovery period. The measurement of hemodynamic variables used a digital photoplethysmography device. Significant differences for SBP (baseline compared to SET2, p = 0.0182) and MAP (baseline compared to SET1, p = 0.0433; and SET2, p = 0.0072) were found. No significant differences were found in the recovery periods compared with baseline. Medium effect size for HR during REC5 (ES = 0.50) and REC10 (ES = 0.56) was observed. These findings indicate that HE in the seated posture performed by normotensive females leads to significant increases in SBP and MAP with no significant increase of HR and no hypotensive effect during recovery period. Our preliminary results should be supported by future randomized controlled trials.

We imagine that you want to be healthy; nobody likes to be ill because that often prevents us from doing the things we like to do. However, we often do not do everything in our power to keep ourselves healthy because modern life is designed to be comfortable. Consequently, we are moving and exercising less than ever, and even young people are suffering the effects of physical inactivity. In this article, we will explain why it is essential for you to move your body, to do so correctly, and to be physically active throughout your life. We will also dispel some myths about children and adolescents lifting weights. There are many things you can do in your daily life to be more physically active!

Although evidence indicates that muscular fitness is foundational for ongoing participation in active play, exercise and sport, current national and international youth physical activity guidelines underplay the critical importance of strength-building activities during this developmental phase of life. In view of troubling trends in muscular fitness in today's youth, specific recommendations to address neuromuscular deficiencies are required. An understanding of the multidimensional development of youth physical inactivity and the importance of muscular fitness are needed to have the most significant impact on youth physical activity at the population level. The mounting evidence of the detrimental effects of physical inactivity on youth warrant a review of existing physical activity recommendations and guidelines. The proposed pediatric activity pyramid recognizes the shared importance of strength, skill, and aerobic activities required for the successful implementation of sustainable youth physical activity interventions.

Temporal trends of youth muscular fitness (i.e., muscular strength, muscular power and local muscular endurance) indicate that contemporary children and adolescents are weaker and slower than previous generations. Consequently, this generation of millennials appear to be just as vulnerable as older adults to the inevitable consequences of muscle disuse and neuromuscular dysfunction. The modern-day construct of pediatric dynapenia describes an identifiable and treatable condition in youth characterized by low levels of muscular strength and power and consequent physical and psychosocial limitations not caused by neurologic or muscular disease. An interaction of modifiable physical and psychosocial factors can influence the development and progression of pediatric dynapenia. Without structured interventions that target strength deficits and build strength reserves in a supporting environment, the divergence in performance between weaker and stronger children may persist into adolescence because weaker youth may be unable to break through a so-called strength barrier. Regular participation in a well-designed youth resistance training program provides an opportunity for youth to enhance their health and fitness while acquiring the physical skills and behaviors that support an active lifestyle. New insights have highlighted the importance of initiating strength-building interventions early in life to optimize performance gains in other important components of physical fitness. Developmentally appropriate resistance training should be integrated into school- and community-based youth fitness programs and strength-building activities should take a more prominent position in public health physical activity recommendations for children and adolescents.

Alonso-Aubin, DA, Picon-Martinez, M, Rebullido, TR, Faigenbaum, AD, Cortell-Tormo, JM, and Chulvi-Medrano, I. Integrative neuromuscular training enhances physical fitness in 6- to 14-year-old rugby players. J Strength Cond Res 35(8): 2263-2271, 2021-The purpose of this study was to assess the effects of an 8-week integrative neuromuscular training (INT) program on physical fitness measures in young rugby players. A sample of 138 male rugby players (age range, 6-14 years) was divided into 5 age-related groups: group 1 (G1) (n = 20; age, 7.05 ± 0.58), group 2 (G2) (n = 27; age, 8.57 ± 0.49), group 3 (G3) (n = 31; age, 11.02 ± 0.56), group 4 (G4) (n = 33; age, 13.12 ± 0.58, and group 5 (G5) (n = 27; age, 14.85 ± 1.53 and additionally into 2 game position groups: forwards (FOR) (n = 69) and backs (BAC) (n = 69). Physical fitness measures included the Functional Movement Screen (FMS), dominant and nondominant hand-to-eye coordination, sprint capacity, core muscular endurance, and lower- and upper-body power. Integrative neuromuscular training (INT) included progressive strength, coordination, and speed exercises performed twice per week for 20 minutes. Following INT, significant improvements in selected age-related groups (p < 0.01) were found in total FMS score G3 (effect size [ES] = 0.47), G4 (ES = 0.88), and G5 (ES = 0.58); dominant hand-to-eye coordination G1 (ES = 1.48), G2 (ES = 0.71), G3 (ES = 0.55), G4 (ES = 1.47), and G5 (ES = 1.15), nondominant hand-to-eye coordination G2 (ES = 0.74), G4 (ES = 1.34), and G5 (ES = 1.09); lower-body power G2 (ES = 0.44), G4 (ES = 0.39), and G5 (ES = 0.43); core muscular endurance G1 (ES = 0.82), G3 (ES = 0.68), and G4 (ES = 1.04); upper-body power G2 (ES = 0.53); and sprint capacity G4 (ES = 0.69). Significant improvements were also found between player's positions for all tests. These findings indicate that a progressive INT program can enhance functional movement abilities and selected physical fitness measures in young rugby players regardless of game position and age.

The aim was to systematically review and meta-analyze the current evidence for the effects of resistance training (RT) on blood pressure (BP) as the main outcome and body mass index (BMI) in children and adolescents. Two authors systematically searched the PubMed, SPORTDiscus, Web of Science Core Collection and EMBASE electronic databases. Inclusion criteria were: (1) children and adolescents (aged 8 to 18 years); (2) intervention studies including RT and (3) outcome measures of BP and BMI. The selected studies were analyzed using the Cochrane Risk-of-Bias Tool. Eight articles met inclusion criteria totaling 571 participants. The mean age ranged from 9.3 to 15.9 years and the mean BMI of 29.34 (7.24) kg/m2). Meta-analysis indicated that RT reduced BMI significantly (mean difference (MD): −0.43 kg/m2 (95% CI: −0.82, −0.03), P = 0.03; I2 = 5%) and a non-significant decrease in systolic BP (SBP) (MD: −1.09 mmHg (95% CI: −3.24, 1.07), P = 0.32; I2 = 67%) and diastolic BP (DBP) (MD: −0.93 mmHg (95% CI: −2.05, 0.19), P = 0.10; I2 = 37%). Limited evidence suggests that RT has no adverse effects on BP and may positively affect BP in youths. More high-quality studies are needed to clarify the association between RT and BP in light of body composition changes throughout childhood and adolescence.

Objective : To comment on how COVID-19 quarantine has affected physical activity in youth and induced a pediatric depreobesity status. Key Points Scarce literature has described the impact of COVID-19 on youth levels of moderate to vigorous physical activity. Physical inactivity and social distancing could lead to physical and psychosocial problems increasing the risk of obesity and depression. Regular moderate to vigorous physical activity plays an essential role to limit or prevent the negative consequences of prolonged quarantine periods on pediatric depreobesity.

Much of the evidence examining temporal trends in fitness among youth has found a decrease in measures of muscular strength and muscular power over recent decades. The aim of this study was to examine trends in lower body muscular power in Spanish boys over 47 years. In 1969 140 boys (10–11 years; body mass index = 19.24, SD = 2.91 kg/m2) and in 2016, 113 boys (10–11 years; body mass index = 19.20, SD = 3.15 kg/m2) were recruited. Lower body power was assessed using the vertical jump (VJ) and standing long jump (SLJ) tests. Significant differences and a large effect size were shown between groups in the SLJ (p = 0.001; d = 0.94) and the VJ (p = 0.001; d = 0.66). SLJ data in 1969 were higher (1.52 m, SD = 0.19) when compared to the 2016 data (1.34 m, SD = 0.18). The VJ performance of the 1969 sample was also higher (25.95 cm; SD = 6.58) than the 2016 sample (21.56 cm; SD = 4.72). SLJ and VJ performance of the 2016 group decreased 11.8% and 16.9%, respectively. There were no significant differences between groups in body mass index. The results indicate a secular decline in lower body muscular power in 10–11-year-old Spanish boys with no significant changes in body mass index over the 47-year study period.

O estudo dos sistemas de sibilantes do galego foi e segue a ser un dos puntos de maior interese para a lingüística galega por constituíren un terreo de profunda inestabilidade e pola dificultade da súa descrición. Neste artigo analízase, dende o enfoque da fonética acústica, o sistema de sibilantes de catro mulleres da localidade de Zas pertencentes a dous grupos de idade diferentes. Desta análise derívase que as mulleres de maior idade presentan un sistema dunha sibilante única, de realización apicoalveolar. Pola contra, no caso das mulleres máis novas, obsérvase un sistema non descrito anteriormente, formado por dúas unidades: a fricativa interdental xorda /θ/ e a sibilante apicoalveolar /s̺/, no que se mantén a despalatalización do /ʃ/ sen se tratar dunha fala seseante.

Due to the unique demands of sport participation on the body, female athletes are at increased risk for pelvic floor dysfunction (PFD) and relative energy deficiency in sport (RED-S). A high number of female athletes suffer from PFD, especially urinary incontinence. Several biomechanical and physiological risk factors may play a role in the development of PFD in female athletes. RED-S has been shown to be associated with PFD. The goal of this commentary is to discuss RED-S as a risk factor for PFD and propose a mechanism for this relationship.

La creciente demanda de clases dirigidas de Ejercicio Hipopresivo (EH) en el ámbito del fitness plantea la necesidad de analizar diferentes aspectos relacionados con dicha actividad en la esfera tanto fisiológica como psicosocial. El objetivo de esta experiencia práctica fue describir las expectativas y beneficios percibidos de mujeres que participan en clases de EH. Fue diseñado un estudio descriptivo sobre una muestra de 14 mujeres (46.86 años, DE=10.15) voluntarias de un centro de fitness de Barcelona (España). Se diseñó un cuestionario auto-administrado realizado ad-hoc para conocer sus expectativas previas, beneficios esperados y percibidos tras realizar dos sesiones semanales de 30 minutos de EH durante 8 semanas dirigidas y supervisadas por un instructor cualificado en Ciencias de la Actividad Física y del Deporte. El análisis de contenido identificó las mismas cinco categorías de expectativas y beneficios percibidos antes del programa así como de beneficios esperados al finalizar el mismo (espalda-postura, suelo pélvico, abdomen, respiración y bienestar general). Se reveló convergencia entre las expectativas iniciales y los beneficios percibidos pero se requiere de futura investigación y de diseños experimentales para determinar si el EH es capaz de satisfacer las expectativas y beneficios esperados por las usuarias. Abstract. The growing demand for hypopressive exercise (HE) group sessions in the fitness field highlights the need to analyze different aspects related to the physiology and psychological sphere of this activity. The aim of this practical experience was to describe previous expectations and perceived benefits of women who attend HE sessions. This descriptive study involved a sample of 14 volunteering women (46.86 years, SD=10.15) from a fitness center in Barcelona (Spain). Was designed a self-administered and ad-hoc questionnaire to know their previous expectations, expected and perceived benefits following a set training period. The sample performed HE twice per week, for eight weeks with a total duration of 30-minutes per session, supervised and directed by an instructor qualified in exercise sciences. The content analysis identified the same five categories of previous expectations and perceived benefits before the HE intervention as well as expected benefits following the eight-week training period (spine-posture, pelvic floor, core, breathing and general well-being). The content analysis revealed convergence between initial expectations and perceived benefits. However, future research is needed to determine if HE is able to satisfy practitioner’ expectations and excepted benefits.

Manual resistance training (MRT) has been widely used in the field of physical therapy. It has also been used as a strength training method due to the accommodating resistance nature of this modality. The aim of the present study was to compare the effects of an 8-week MRT program on maximum strength and muscular endurance in comparison to conventional resistance training in recreationally trained men. Twenty healthy recreationally trained male subjects were recruited and divided into a MRT training group and a conventional training (CT) group. CT group performed bench press and lat pull-down exercises, and the MRT group performed similar movements with resistance provided by a personal trainer. Both groups completed similar training protocol and training load: 2 training sessions weekly for 3 sets of 8 repetitions at an intensity of 8 to 10 on the perceived exertion scale of 0-10. Initial maximum strength differences were not significant between the groups. Neither group showed significant changes in muscular strength or endurance. Despite the statistically non-significant pre- to post differences, a trend for improvement was observed and effect size (ES) calculations indicated greater magnitude of effects for strength and endurance changes in the MRT group in lat pulldown (g=0.84) compared to CT group. Effectiveness of MRT is similar to CT for improving muscular strength and endurance. MRT can be used as a supplemental or alternative strength training modality for recreationally trained subjects, or be considered by personal trainers especially in low equipped facility conditions.

Alonso-Aubin, DA, Chulvi-Medrano, I, Cortell-Tormo, JM, Picón-Martínez, M, Rial-Rebullido, T, and Faigenbaum, AD. Squat and bench press force-velocity profiling in male and female adolescent rugby players. J Strength Cond Res 35(2S): S44-S50, 2021-Power development is critical for enhancing rugby performance because there is a close relationship between power and sport-specific skills. The aim of this study was to examine the force-velocity profiling generated by adolescent rugby players in the squat and bench press exercises and to compare sex-related differences. Subjects were 46 men (age: 14.48 ± 1.31 years; body height: 1.65 ± 0.09 m; and body mass: 58.07 ± 13.01 kg) and 41 women (age: 14.93 ± 2.76 years; body height: 1.63 ± 0.12 m; and body mass: 59.23 ± 12.66 kg) who were recruited from a national amateur rugby league team. Maximal strength, power, and velocity were assessed on the squat and bench press exercises using a Smith Machine and a linear power transducer with intensities ranging from 40 to 80% 1 repetition maximum (1RM) on the squat and 50-80% 1RM on the bench press. 1 repetition maximum squat and bench press performance were 104.26 ± 30.83 and 46.97 ± 13.59 kg, respectively, for men and 115.17 ± 41.42 and 45.85 ± 16.71 kg, respectively, for women. The maximum squat power results for men and women were 521.91 ± 298.75 and 591.26 ± 352.69 W, respectively, and the maximum bench press power results for men and women were 190.26 ± 150.54 and 326.16 ± 195.57 W, respectively. Significant sex-related differences (p0.001) were found on the squat exercise for maximum (40%), mean (40-50%), and time to maximum velocities (40-80%) as well as time to maximum power (80%). On the bench press exercise, significant sex-related differences (p0.001) were found for power and time to maximum velocity (40%-60%-70%-80%). These results may aid in the design of strength and conditioning programs for adolescent rugby players by targeting training prescriptions toward enhancing strength or velocity.

Background Cancer-related fatigue (CRF) is a common symptom during and after cancer treatment that negatively affects the patient's quality of life. Exercise is one of the most effective non-pharmacological treatments for CRF. Multimodal exercise therapy programs that include hypopressive exercises, relaxation and myofascial release may be beneficial for CRF. The aim of this pilot study was to evaluate the feasibility and efficacy of a multimodal program on CRF and lower limb functional strength in postmenopausal women diagnosed with cancer. Methods 7 postmenopausal women (age = 55.28 years; BMI = 26.05 kg/m2) who had a cancer diagnosis participated in a supervised and progressive 55-min class once per week for 12-weeks. CRF was measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Cancer Related Fatigue 12 and lower limb strength was assessed with the sit and stand test. Results No adverse events were reported during the training period and all participants completed the exercise protocol. There was a significant increase (p = 0.01) in lower limb functional strength (pre: 19.60 (SD = 2.19) vs post: 24.60(SD = 2.19)) with an effect size of d = 2.28 and a decrease in CRF (p = 0.245) (pre: 29.36 ± 24.42; post: 17.85 ± 14.23) with a trivial effect size (d Conclusions These preliminary findings indicate that a supervised once per week multimodal program that includes hypopressive exercises for postmenopausal cancer survivors increased lower limb functional strength without exacerbating their CRF. These findings support further randomized trials of hypopressive training programs on patients with cancer.

This review aimed to synthesize the most up-to-date evidence regarding the prevalence of urinary incontinence (UI) among adolescent female athletes. We conducted a systematic review of studies regarding UI in female athletes less than 19 years of age. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRIMSA). The electronic databases of PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and Web of Science (WOS) were searched between October and November 2020. After blinded peer evaluation, a total of 215 studies were identified and nine were included. Risk of bias was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. This review identified a prevalence of UI in adolescent female athletes between 18% to 80% with an average of 48.58%. The most prevalent sports were trampolining followed by rope skipping. The prevalence of UI among adolescent female athletes practicing impact sports was significantly prevalent. There is a need for further research, education, and targeted interventions for adolescent female athletes with UI.

La Técnica Hipopresiva (TH) se basa en posturas de estiramiento sostenidas mientras se realizan respiraciones torácicas y apneas intermitentes. Existe poca evidencia sobre sus efectos en la musculatura abdominal y del Suelo Pélvico (SP), así como en otras variables cineantropométricas, especialmente en mujeres deportistas. El objetivo del estudio fue describir los efectos de un programa basado en la TH sobre la composición corporal, contracción del transverso del abdomen (TA) y función muscular del SP de mujeres deportistas. La muestra estuvo formada por 11 jugadoras de rugby (23.3años, SD = 2,69; 23.3; IMC, SD = 1,98) que realizaron ocho posturas de la TH, realizadas en sesiones de 45 minutos, dos veces por semana a lo largo de ocho semanas. Todas las sesiones fueron supervisadas por una fisioterapeuta cualificada. Se evaluó la composición corporal a través de impedancia bioeléctrica y la circunferencia de la cadera y cintura se midieron con cinta antropométrica. La máxima contracción del TA se evalúo con biofeedback de presión. Para analizar la tonicidad y contractilidad muscular del SP se utilizó un pelvímetro Phenix. Se observaron diferencias significativas tras el periodo de entrenamiento en la circunferencia de la cintura, la máxima contracción del TA y en la contractilidad y tonicidad de la musculatura del SP (p.05). Estos resultados preliminares indican que un programa supervisado de ocho semanas de la TH puede ser utilizado para mejorar la función abdominal y del SP de jugadoras de rugby.Abstract. The hypopressive technique (HT) uses active muscle stretching postures in conjunction with thoracic breathing and intermittent breath holding. There is little evidence about the effects of HT on the deep musculature of the abdomen and the pelvic floor (PF) as well as other kinanthropometric variables, especially in female athletes. The aim of this study was to examine the effects of HT program on body composition, contraction of the transversus abdominis (TA) and PF muscle function in female athletes. 11 female rugby players (23.3yr, SD=2.69; 23.3; BMI, SD=1.98) performed eight HT postures twice per week for 8 weeks with a total duration of 45-minutes per session. All training sessions were supervised by a qualified HT physiotherapist. Body composition was evaluated through bioelectrical impedance and waist and hip circumferences were measured with anthropometric tape. Maximum contraction of the TA was assessed with a biofeedback pressure device. The pelvimetre Phenix was used to analyze tonicity and PF contractility. Following the training period, significant differences were observed in waist circumference, maximum contraction of the TA and contractility and muscle tone of the PF (p.05). These preliminary findings indicate that a supervised 8-week program of HT can be used to enhance abdominal and perineal function in female rugby players.

A Ginástica Abdominal Hipopressiva (GAH) é um método combinado de exercícios posturais e respiratórios. Nos exercícios respiratórios, é realizado a manobra de mueller (ação inspiratória com a glote fechada), uma manobra respiratória, em apneia após a expiração. Manobras respiratórias produzem alterações no sistema cardiovascular, portanto conhecer a hemodinâmica neste método se torna relevante. O objetivo foi observar o comportamento da pressão arterial sistólica (PAS), pressão arterial diastólica (PAD), débito cardíaco (DC) e frequência cardíaca (FC) durante e após uma sessão de GAH. Dez mulheres (n=10) realizaram uma sessão de GAH de 3 séries de 8 apneias, de 10 segundos, precedidas de 3 ciclos respiratórios, intervalo de 1 min. entre as séries. A PAS, PAD, FC e DC foram monitorados antes da sessão, 10 minutos após repouso; ao final de cada série, durante a sessão e; 5, 10, 15 e 20 min. após a sessão através do Finometer (FMS, Arnhem, Holanda). Análise estatística, foi utilizado ANOVA e Kruskal-Wallis seguido do teste de Dunns para comparações múltiplas das médias dos momentos monitorados. A PAS e a PAD aumentaram de forma significativa durante a sessão (PAS=p
