Cardio-respiratory values during recovery from exercise in soccer Spanish leagues.

OBJECTIVE: In this cross-sectional study, we compared Spanish division one (n = 114) and division two (n = 80) soccer players in terms of their cardio-respiratory response during recovery following a maximum laboratory effort test. APPROACH: Following the maximum laboratory effort protocol, we measured oxygen consumption ([Formula: see text]), heart rate (HR), and ventilation ([Formula: see text]) during recovery. MAIN RESULTS: Over the first 60 s of recovery, no significant differences were seen in either [Formula: see text] (28.7 versus 28.3 ml/kg/m, in division one and two players, respectively), HR, or [Formula: see text] (p > 0.05). After 90 s, however, significant differences appeared between the players of the two divisions (p < 0.01), although not among playing positions. Significant differences in [Formula: see text] (21.1 versus 26.0 ml/kg/m, in division one and two players, respectively) and HR were still apparent at 180 s into the recovery period. The change in professional soccer players' cardio-respiratory values over the recovery period following maximum effort are independent of the position played, but are associated with the division in which a player competes. Second division players show significantly higher [Formula: see text] and HR values than first division players at 180 s into the recovery period. SIGNIFICANCE: These differences might influence performance in soccer and in other athletes whose sports require intermittent bouts of maximum effort and consequently times to repeat high-intensity efforts as short as possible.

Ultrasound-guided percutaneous lavage of calcific bursitis of the medial collateral ligament of the knee: a case report and review of the literature.

OBJECTIVES: Calcification of the medial collateral ligament (MCL) of the knee is rare. The literature reports no positive outcomes when conservative treatment has been followed. This paper reports a case of such calcification and its treatment using ultrasound-guided percutaneous lavage (UGPL). METHODS: A 66-year-old patient presented with medial knee pain. X-ray, ultrasound, and magnetic resonance (MR) examinations revealed calcific bursitis of the MCL, which was treated by UGPL. RESULTS: One month after treatment the patient was asymptomatic. X-ray, ultrasound, and MR examinations confirmed the almost complete disappearance of the calcification; only very tiny fragments remained. CONCLUSIONS: Calcific bursitis of the MCL of the knee is very uncommon, but should be taken into account in differential diagnoses for medial knee pain. UGPL is proposed as a treatment for this condition.

Estudio comparativo entre deportes simétricos y asimétricos mediante análisis estructural estático en deportistas adolescentes / Comparative study between symmetrical and asymmetrical sports by static structural analysis in adolescent athletes

En los exámenes médicos preparticipación deportiva, el análisis de las estructuras anatómicas que no están directamente relacionadas con el deporte en cuestión, suele ser más superficial. Un examen más detallado del aparato locomotor podría revelar la existencia de ciertas anomalías que, en ocasiones pueden pasar desapercibidas. El objetivo de este estudio es describir la prevalencia de trastornos estructurales del aparato locomotor en una población de deportistas adolescentes de élite de la Comunidad de Madrid. Establecer la relación de alteraciones con la práctica de deportes simétricos o asimétricos. Estudio transversal descriptivo. Nivel de evidencia II-III. Nuestra población de estudio incluye deportistas pertenecientes al plan de tecnificación de la Comunidad de Madrid: 102 deportistas, 66 hombres y 36 mujeres con edades comprendidas entre 12 y 19 años. Un grupo control está compuesto por deportistas de natación, deporte considerado simétrico y el segundo grupo por deportistas practicantes de deportes considerados asimétricos: esgrima y bádminton. Los deportistas fueron examinados siguiendo un método cegado por tres diferentes especialistas que utilizaron el mismo protocolo. Se ha empleado el contraste de hipótesis para variables cualitativas, con un nivel de confianza del 95% (p<0,05). Noventa y seis deportistas (94,1%) presentaron algún tipo de alteración estructural y /o postural en los exámenes médicos preparticipación deportiva. No encontramos correlación significativa (p<0,05) ) entre los diferentes deportes en las alteraciones en la columna vertebral, las rodillas, las extremidades y la huella plantar, independientemente fueran simétricos o asimétricos (p<0,05). Conclusiones: Nuestro estudio muestra una alta prevalencia de variaciones estructurales en los adolescentes que practican deporte de alto nivel. No encontramos relación entre practicar un deporte asimétrico y la prevalencia de escoliosis u otra alteración músculo-esquelética

In pre-participative sports medical examinations, the analysis of the anatomical structures that are not directly related to the sport in question, is usually more superficial. A more detailed assessment of the locomotive system may reveal the existence of certain anomalies, which may occasionally go unnoticed. The aim of this study is to describe the prevalence of structural disorders of the locomotive system among elite-level athletes from the Community of Madrid. To establish the relationship between alterations and practising symmetrical or asymmetrical sports. Descriptive cross-sectional study Level of evidence II-III Our study sample includes athletes that are members of the Community of Madrid Sports Technification Plan. 102 athletes, 66 males and 36 females aged between 12 and 19 years. One control group comprises swimming athletes, a sport considered to be symmetrical, and the second group comprises athletes practising sports considered to be asymmetrical: fencing and badminton. The athletes were examined following a blind method by three different specialists using the same protocol. Hypothesis contrasting has been used for qualitative variables, with a 95% confidence level (p<0.05). Ninety-six athletes (94.1%) displayed some kind of structural and/or postural alteration in the pre-participative sports medical examinations. No significant correlation was found (p<0.05) between the different sports on alterations to the spine, knees, extremities and footprint, regardless of whether they were symmetrical or asymmetrical (p<0.05). Conclusions: Our study revealed a high prevalence of structural variation in high-level adolescent athletes. No relationship was found between practising an asymmetrical sport and the prevalence of scoliosis or other muscular-skeletal alterations

Extracorporeal shockwaves versus ultrasound-guided percutaneous lavage for the treatment of rotator cuff calcific tendinopathy: a randomized controlled trial.

BACKGROUND: Extracorporeal shockwave treatment (ESWT) and ultrasound-guided percutaneous lavage (UGPL) are two effective ways of treating rotator cuff calcific tendinopathy (RCCT). AIM: The aim of the present study was to compare the effectiveness of these techniques in the treatment of RCCT. DESIGN: Prospective, randomized, controlled trial. SETTING: Patients treated in our sports medicine and rehabilitation center (Centro Médico Deyre, Madrid. Spain) between January 2007 and December 2013. METHODS: This randomized study compares the results achieved with these techniques over one year following their use to treat the above condition. Eighty patients received ESWT and 121 received UGPL. A visual analogue scale was used to measure pain, and ultrasound to determine the extent of calcification, at 3, 6, and 12 months after treatment. RESULTS: Pain and the amount of calcification were significantly reduced by both techniques at 3, 6 and 12 months (P<0.001 for each), but significantly more so by UGPL (P<0.001). CONCLUSIONS: Both techniques are valid for the treatment of RCCT, although UGPL is associated with a greater reduction of calcification and greater reduction in pain. CLINICAL REHABILITATION IMPACT: The results obtained applying UGPL, the low cost and the lack of complications should therefore make the treatment of choice in centers that are appropriately equipped and staffed.
