Postural control and physiological responses to a simulated match in U-20 judo competitors.

The aim was to evaluate the effects of judo combat on the athletes' postural control (PC) and physiological loading before, during and after a simulated match. Seventeen under-20 regional and national level athletes completed one modified 7-min match. At baseline, during the combat (3rd and 7th minutes) and 2-min post-match centre of pressure (CoP) parameters were assessed. Heart rate (HR), blood lactate (BLa) and rating of perceived exertion (RPE) and local RPE (LRPE) were collected. Significant increments were observed in CoP mean positioning and velocity at 3rd and 7th minutes, but the CoP deviation in both axes was unaffected. HR and BLa were elevated at 3rd and 7th minutes, and they remained elevated 2-min post-match. However, CoP returned to baseline 2-min post-match. RPE was elevated at 3rd and 7th minutes and the greatest effort was displayed in the Deltoid and Quadriceps. Thus, one simulated judo match stimulates a significant metabolic response and balance is degraded, with the greatest effects on the anterior-posterior axis and it recovers to baseline level after 2 min of passive rest. The physiological load cannot be regarded as a potential predictor variable of CoP. Overall, a judo match predominantly affects the upper body than the other body parts.

Effects of progressive resistance exercise in akinetic-rigid Parkinson's disease patients: a randomized controlled trial.

BACKGROUND: Progressive resistance exercise (PRE) can have a positive effect in individuals with Parkinson's disease (PD). However, the effect of PRE may vary with the clinical subtype of PD. To date, no study has assessed the effects of PRE in the different subtypes of PD. AIM: The aim of the present study was to assess the effects of PRE in PD patients with akinesia and rigidity (AR-subtype). DESIGN: A randomized controlled trial was conducted. SETTING: Outpatients clinics of the Bierzo Parkinson Association (Ponferrada, Spain) and the Asturias Parkinson Association (Oviedo, Spain). POPULATION: Twenty-eight patients with AR-subtype PD were randomized into an Experimental Group (EG, N.=13) and Control Group (CG, N.=15). METHODS: Static posturography (Centre of Pressure -CoP- parameters), gait (the Ten-Meter Walk Test [TMWT]), freezing of gait (the Freezing of Gait Questionnaire [FOG-Q]), the motor portion of the Movement Disorders Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and patient-perceived quality of life (the 39-item Parkinson's disease Questionnaire [PDQ39]), were assessed at pre-test, post-test, and re-test. Ratings of perceived exertion (RPE) (Borg >6-20 Scale) were recorded at the end of each PRE training session. RESULTS: The EG displayed significant ameliorations in Length (CoP parameters) from pre- to post-test (P=0.048), in speed of fast rhythm walking (TMWT) from pre- to post-test (P=0.000), and from pre- to re-test (P=0.027), and in the PDQ39 Score from pre- to post-test (P=0.024). No significant differences were detected in Area or Speed (CoP parameters), speed of preferred rhythm walking (TMWT), FOG-Q scores, or the motor portion of the MDS-UPDRS scores. The EG reported a mean RPE of 9.95 (between "very light" and "fairly light") for the whole training program. CONCLUSIONS: These findings provide support for the use of PRE training in the rehabilitation of individuals with AR-subtype PD, as it can improve static posturography, gait, and quality of life. Furthermore, RPE scores showed that individuals with AR-subtype PD consider that PRE training require only light efforts. CLINICAL REHABILITATION IMPACT: The PRE training can be a helpful and fruitful rehabilitation tool for AR-subtype PD patients.

Effects of supervised slackline training on postural instability, freezing of gait, and falls efficacy in people with Parkinson's disease.

PURPOSE: The aim of this study was to assess whether supervised slackline training reduces the risk of falls in people with Parkinson's disease (PD). METHODS: Twenty-two patients with idiopathic PD were randomized into experimental (EG, N = 11) and control (CG, N = 11) groups. Center of Pressure (CoP), Freezing of Gait (FOG), and Falls Efficacy Scale (FES) were assessed at pre-test, post-test and re-test. Rate perceived exertion (RPE, Borg's 6-20 scale) and local muscle perceived exertion (LRPE) were also assessed at the end of the training sessions. RESULTS: The EG group showed significant improvements in FOG and FES scores from pre-test to post-test. Both decreased at re-test, though they did not return to pre-test levels. No significant differences were detected in CoP parameters. Analysis of RPE and LRPE scores revealed that slackline was associated with minimal fatigue and involved the major lower limb and lumbar muscles. CONCLUSIONS: These findings suggest that slacklining is a simple, safe, and challenging training and rehabilitation tool for PD patients. It could be introduced into their physical activity routine to reduce the risk of falls and improve confidence related to fear of falling. Implications for Rehabilitation Individuals with Parkinson's disease (PD) are twice as likely to have falls compared to patients with other neurological conditions. This study support slackline as a simple, safe, and challenging training and rehabilitation tool for people with PD, which reduce their risk of falls and improve confidence related to fear of falling. Slackline in people with PD yields a low tiredness or fatigue impact and involves the major lower limb and lumbar muscles.

[Relation between the perception of the aerobic capacity and the VO 2max in firemen]. / Relación entre la percepción de la capacidad aeróbica y el VO2máx en bomberos.

Relation between the perception of the aerobic capacity and the VO 2max in firemen. For a fireman, knowing whether he is fit enough for his job implies regulating the intensity of the rescue without causing premature body fatigue. Therefore, the main purpose of this study is to determine the real aerobic capacity in a sample of firemen, based on the VO 2máx , and to compare it with two self-report measures: the subjective appraisal of aerobic capacity and the appraisal of the physical exercise carried out. Thus, 37 firemen from Asturias took part in this study and performed effort tests on a treadmill, measuring their heart frequency and VO 2máx consumption. Of the firemen, 94.4% who obtained a VO 2máx below 43 ml/min/kg (the minimum advised to perform their job effectively) considered their aerobic capacity to be <> or <>. This might be influenced by the lack of feedback on their aerobic capacity, as their training is voluntary and self-planned. Therefore, it is highly recommended to program specialized training and to carry out periodical tests to provide feedback about aerobic capacity.

Relación entre la percepción de la capacidad aeróbica y el VO2máx en bomberos / Relation between the perception of the aerobic capacity and the VO2max in firemen

Para un bombero, conocer su estado de forma implica regular la intensidad del rescate sin provocar una fatiga prematura. El objetivo principal del estudio es conocer la capacidad aeróbica real (CAR) de una muestra de bomberos basada en su VO2máx y compararla con dos medidas autoinformadas: la valoración subjetiva de su capacidad aeróbica (VSCA) y la valoración del ejercicio físico realizado (VEF). Participaron 37 bomberos del Principado de Asturias. Se realizaron pruebas de esfuerzo hasta la extenuación en una cinta sin fin, midiendo la frecuencia cardíaca y el consumo VO2máx. El 94,4% de los bomberos que obtuvieron un VO2máx por debajo de 43 ml/min/Kg (mínimo aconsejado para desarrollar su trabajo eficazmente) consideró su capacidad aeróbica «alta» o «muy alta». Esto podría ser influenciado por la falta de información que reciben sobre su capacidad aeróbica a causa de un entrenamiento voluntario y autoprogramado. Se aconseja planificar entrenamientos supervisados por un especialista y realizar test periódicos que informen del la capacidad aeróbica (AU)

Una dorsalgia peligrosa / A dangerous pain back

El dolor de espalda, no tiene que tener necesariamente un origen musculoesquelético, por lo que hemos de ser rigurosos al estudiar nuestros pacientes y contemplar todo tipo de posibilidades. La prescripción de las diferentes terapias, se ha de hacer después de confirmar el diagnóstico en el que los datos del historial clínico, la exploración y la evolución, deben de poner en guardia al clínico frente a patologías no habituales en el día a día del médico deportivo. La principal enseñanaza de este caso clínico es recordar el concepto global de la medicina que debe regir nuestras actuaciones, con independencia de la especialidad que ejerzamos cada uno y, la necesidad de mantener vínculos con otros profesionales en los que apoyarse

Relación de la actividad física con el consumo de tabaco en adolescentes / Connection between physical activity and smoking habits of teenagers

El objetivo de este estudio se basa en conocer el porcentaje de adolescentes de 12 a 16 años que realizan actividad física habitualmente así como los sedentarios, saber el porcentaje de fumadores y establecer una relación entre el hábito tabáquico con las diferentes formas de ejercicio físico (individual, colectiva, aerobia y anaerobia), además de otras variables como sexo, edad, hábitos tabáquicos familiares... Han participado 367 adolescentes entre 12 y 16 años, pertenecientes a los tres modelos de sistema educativo actual (público, concertado y privádo). Las mediciones e intervenciones para la obtención de datos consistieron en la realización de una encuesta epidemiológica sobre consumo y dependencia del tabaco, así como de la práctica deportiva realizada en adolescentes. Como resultados más destacados diremos que el 61,9 por ciento de la muestra no han probado nunca el tabaco (65,4 por ciento de los chicos y 57,6 por ciento de las chicas), el 18 por ciento afirmaron haber probado el tabaco alguna vez (5,6 por ciento de los chicos y 4,1 por ciento de las chicas), un 4,9 por ciento se consideran ex/fumadores, y fuman habitualmente un 15,1 por ciento, el 6,8 por ciento esporádicamente (fin de semana) y el 8,2 por ciento (7,1 por ciento de los chicos y 9,4 por ciento de las chicas) diariamente. La edad media de inicio en el consumo de tabaco en nuestro estudio ha sido de 12,2 años ñ1,84. Un 31,5 por ciento de los alumnos sólo realizan actividad física durante las clases de educación física, mientras que un 68,1 por ciento lo realizan habitualmente fuera del centro educativo (un 44,1 por ciento son federados). Encontramos significación estadística entre fumar y no realizar actividad física (p<0,01), y dentro de los que practican deporte fuman menos los que están federados (p<0,01). No es significativo el fumar con el tipo de sistema energético utilizado (aerobio, anaerobio y mixto), ni con el tipo de deporte (individual o colectivo), pero si lo es con la convivencia con fumadores (p < 0,01). Concluimos que la muestra estudiada es activa y poco fumadora. Podemos afirmar que la actividad física influye de manera importante en la actitud del adolescente respecto al tabaco y evita en gran medida el inicio a su consumo y más aún dentro del grupo de federados. El hábito de fumar en la familia del adolescente se relaciona significativamente con la adquisición del hábito tabáquico por parte del mismo (AU)
