Randomized, controlled trial on chronic nonspecific low back pain JF - Der Schmerz : Organ der Deutschen Gesellschaft zum Studium des Schmerzes, der Österreichischen Schmerzgesellschaft und der Deutschen Interdisziplinären Vereinigung für Schmerztherapie N2 - Back pain is a complex phenomenon that goes beyond a simple medical diagnosis. The aetiology and chronification of back pain can be best described as an interaction between biological, psychological, and social processes. However, to date, multimodal prevention and intervention programs for back pain that target all three aetiological factors have demonstrated limited effectiveness. This lack of supportive evidence for multimodal programmes in the treatment of back pain could be due to the fact that few programs are suitable for long-term and unsupervised use in everyday life. Moreover, in combining the elements from various therapies, little attention has been paid to the mechanisms underlying the synergistic effects of the separate components. In this contribution, we will describe the development of a new multimodal intervention for back pain that set out to address these limitations. To this end, the biological elements of neuromuscular adaptation is supplemented with cognitive behavioral and psychophysiological techniques in an intervention that can be followed at home as well as in clinics, and that is suitable for all grades of pain. The efficacy of this intervention will be tested in a multicentric randomized controlled longitudinal trial (n = 714) at five time points over a period of 6 months. Here we will describe the development and the content of this new intervention.

Knapp ein Drittel der jährlichen Trainingsausfallzeiten werden auf CURS zurückgeführt. In der Entstehung von chronischen Schmerzen ist ein multifaktorielles Ätiologiemodell mit einem signifikanten Einfluss psychosozialer Risikofaktoren evident. Obwohl dies in der Allgemeinbevölkerung bereits gut erforscht ist, gibt es in der Sportwissenschaft vergleichsweise wenige Arbeiten darüber. Dieses Thema wird daher in drei Multicenterstudien und zahlreichen Teilstudien des MiSpEx-Netzwerks (Medicine in Spine-Exercise-Network, Förderzeitraum 2011 – 2018) aufgegriffen. Entsprechend der Empfehlung einer frühzeitigen Diagnostik von Chronifizierungsfaktoren in der „Nationalen Versorgungsleitlinie Kreuzschmerz“, beschäftigt sich das Netzwerk u. a. mit der Überprüfung, Entwicklung und Evaluation diagnostischer Möglichkeiten. Der vorliegende Beitrag beschreibt die Entwicklung einer Diagnostik von psychosozialen Risikofaktoren, die einerseits eine Einschätzung des Risikos der Entwicklung von CURS und andererseits eine individuelle Zuweisung zu (Trainings)Interventionen erlaubt. Es wird die Entwicklungsrationale beschrieben und dabei verschiedene methodische Herangehensweisen und Entscheidungssequenzen reflektiert. N2 - Chronic nonspecific low back pain (CLBP) is one of the most common pain syndromes globally. Attributing to one third of missed training days, CLBP can seriously affect athletes’ careers. Studies in the general population show a multifactorial etiology with significant influence of psychosocial risk factors in the development of CLBP. As less is known about this phenomenon in athletes, the MiSpEx Network (Medicine in Spine Exercise, funded from 2011 to 2018) has conducted three multicenter studies and numerous substudies investigating this topic. The network has been concerned with the testing, development, and evaluation of diagnostics, in accordance with the recommendation of the German National Treatment Guidelines for CLBP that risk factors be recognized and treated early. Our article describes the development of a diagnostic tool for psychosocial risk factors that allows (medical) practitioners to predict the occurrence of CLBP and to suggest individualized (trainings) interventions. We present the methodological approach and discuss various methodological issues.

Data analyzing clinical or biomechanical effects of those interventions is sparse. Foot orthoses out of carbon fiber are one possibility to alter the interface between foot and pedal. The aim of this study was therefore to analyze plantar pressure distribution in carbon fiber foot orthoses in comparison to standard insoles of commercially available cycling shoes. Materials and Methods: 11 pain-free triathletes (Age: 29 +/- 9, 1.77 +/- 0.04 m, 68 5 kg) were tested on a cycle ergometer at 60 and 90 rotations per minute (rpm) at workloads of 200 and 300 Watts. Subjects wore in randomized order a cycling shoe with its standard insole (control condition CO) or the shoe with carbon fiber foot orthoses (Condition CA). Mean peak pressure out of 30 movement cycles were extracted for the total foot and specific foot regions (rear, mid, fore foot (medial, central, lateral) and toe region). Three-factor ANOVAs (factor foot orthoses, rpm, workload) for repeated measures (alpha = 0.05) were used to analyze the main question of a foot orthoses effect on peak in-shoe plantar pressure. Results: Peak pressures in the total foot were in a range of 70-75 kPa for 200 Watts (W) (300 W: 85-110 kPa). The carbon fiber foot orthoses reduced peak pressures by -4,1% compared to the standard insole (p = 0,10). In the foot regions rear(-16,6%, p<0.001), mid (-20,0%, p<0.001) and fore foot (-5.9%, p < 0.03)CA reduced peak pressure compared to CO. In the toe region, peak pressure was higher in CA (+16,2%) compared to CO (p<0,001). The lateral fore foot showed higher peak pressures in CA (+34%) and CO (+59%) compared to medial and central fore foot. Conclusion: Carbon fiber can serve as a suitable material for foot orthoses manufacturing in cycling. Plantar pressures do not increase due to the stiffness of the carbon. Individual customization may have the potential to reduce peak pressure in certain foot areas.

(DGSP) und Weiterbildungsorgan der Österreichischen Gesellschaft für Sportmedizin und Prävention N2 - Since the legend of the ancient Marathon run, the risk of endurance exercise-induced cardiovascular damage or sudden cardiac death is discussed. In recent studies, the exercise-induced increases in cardiac biomarkers in endurance athletes as well as acute alterations in cardiac function and cardiovascular abnormalities have been reported. As elevations of the cardiac biomarkers troponin and BM) have been observed frequently for the vast majority of athletes after Marathon runs or strenuous exercise bouts followed by a decrease within a short period, a physiological reaction rather than a pathologicial cause is presumed. Also a transient decrease of cardiac function demonstrated by newer echocardiographic techniques (tissue Doppler or speckle tracking imaging, 3D echocardiography) after strenuous exercise often termed "cardiac fatigue" should not be considered necessarily as pathologic, as cardiac function also depends on hemodynamic load and heart rate. Furthermore, exercise-induced changes in cardiac function did not correlate with exercise-induced increases in cardiac biomarkers in most studies. The functional cardiac alterations can also be detected by magnetic resonance imaging (MRI) after Marathon runs. However, no signs of acute or chronic myocardial damage have been demonstrated in MRI studies in cardiovascular healthy athletes after running a Marathon, although especially in older athletes undetected cardiovascular diseases such as coronary artery disease or myocardial necrosis or fibrosis can be present. hi conclusion, according to recent studies. there seems to be a lack of evidence to support endurance exercise-induced cardiac damage in the healthy heart which is adapted tostrenous exercise by regular endurance training. Nevertheless, as running a Marathon results in a high cardiac load, a sufficient endurance training period as well as a preparticipation or regular medical screening to exclude relevant congenital or aquired cardiovascular diseases is recommended from a sports cardiology perspective to exclude relevant congenital or acquired cardiovascular diseases KW - Marathon KW - cardiac biomarkers KW - endurance exercise KW - athlete's heart KW - cardiac fatigue Y1 - 2011 SN - 0344-5925 VL - 62 IS - 9 SP - 293 EP - 298 PB - WWF-Verl.-Ges.

Differentiated information about the roll- over process of the foot, represented by the "Center of Pressure" (COP), are still missing. The purpose of the study was the validation of the COP-path to quantify the functional gait development of children. Plantar pressure distribution was measured barefoot with an individual speed on a walkway (tartan) - in 255 children aged between 2 and 15 years. The medial and lateral area enclosed between the COP-path and the bisection of plantar angle (A(med), A(lat), Sigma: A(ml)) was calculated from plantar pressure data. Furthermore, the duration of the COP-path in the heel (COPtimeF), midfoot (COPtimeM) and forefoot (COPtimeV) was analysed. The load distribution under the medial and lateral forefoot was also calculated. The variation coefficient (VC) was calculated as a measure of interindividual variability. The medio-lateral divergency of the COP (Aml) initially decreases with advancing age (-20.2%), followed by a continuous increase (+27.2%). No changes in VC (A(med), A(lat), and A(ml)) appeared during age-related development. COPtimeM remains constant in all children over time. In contrast to COPtimeM, Cop(time)F decreases from youngest to oldest children (-31.0%), and COPtimeV increases (+41.7%). After initial descent up to 8 years of age, VC (COPtimeF, COPtimeM, COPtimeV) remains constant. The mediolateral load under the forefoot did not change. The COP-Path is able to characterise the functional gait development of children. VC values indicate high individual variability of gait pattern. In this context, age-based standard values should be critically discussed Y1 - 2006 ER - TY - JOUR A1 - Hirschmueller, Anja A1 - Frey, Virginie A1 - Deibert, Peter A1 - Konstantinidis, Lukas A1 - Mayer, Frank A1 - Suedkamp, Norbert A1 - Helwig, Peter T1 - Powerdopplersonografische Befunde der Achillessehnen von 953 Langstreckenlaeufern : eine Querschnittsstudie N2 - Aim: The aim of this cross-sectional study was to assess the frequency of tendinopathy-typical Doppler sonographic changes in the Achilles tendons of long distance runners and to correlate these findings with anamnestic and anthropometric data of the subjects. Materials and Methods: 1906 Achilles tendons of 953 long distance runners were examined by ultrasound and power Doppler (Toshiba Aplio SSA-770A/80 12 MHz). Ultrasound images (spindle-shaped thickening, hypoechoic/hyperechoic lesions, neovascularizations) were analyzed in relation to the runners' anthropometrical data and history of Achilles tendon complaints. Results: In asymptomatic runners as well as in the overall group, there was a statistically significant correlation between tendon thickness and age, height and weight (CC 0.24 - 0.38, p < 0.001). Runners with current or healed Achilles tendon complaints displayed a statistically significant thickening of the tendons, as well as an increase in hypoechoic lesions and neovascularizations (p < 0.001). While grayscale abnormalities were rarely found in asymptomatic runners (< 10%), neovascularization was detected in 35% of healthy test persons using the high-resolution power Doppler "Advanced Dynamic Flow". Conclusion: Contrary to frequent assumption, neovascularization is often found in tendons of asymptomatic runners, using modern power Doppler equipment. The pathological relevance of single microvessels in asymptomatic tendons must, therefore, be critically discussed.

The purpose of the study was to investigate underreporting among persons of normal weight with a very high energy intake (El). The total energy expenditure (TEE) of 16 elite athletes (BMI 24 +/- 2 kg/m(2)) and 17 controls (BMI 23 3 kg/m2) was measured using the doubly-labeled water technique (DLW, 14d). El was estimated using 2 x 3-day dietary records. Underreporters were identified by BLACK'S cut-off (El:TEE < 0.76). 44% of athletes (El: 3584 824 kcal/d; TEE: 4621 1460 kcal/d) and 29% of controls (El: 2552 680 kcal/d; TEE: 3151 822 kcal/d) were identified as underreporters. TEE explains 52% of underreporting. In summary, a high energy intake seems to strongly predict underreporting. Prevalence and magnitude of underreporting increase with increasing energy intake.
