  abstract  = {The purpose was to examine gender differences in ankle stabilizing muscle activation during postural disturbances. Seventeen participants (9 females: 27 +/- 2yrs., 1.69 +/- 0.1 m, 63 +/- 7 kg; 8 males: 29 +/- 2yrs., 1.81 +/- 0.1 m; 83 +/- 7 kg) were included in the study. After familiarization on a split-belt-treadmill, participants walked (1 m/s) while 15 right-sided perturbations were randomly applied 200 ms after initial heel contact. Muscle activity of M. tibialis anterior (TA), peroneus longus (PL) and gastrocnemius medialis (GM) was recorded during unperturbed and perturbed walking. The root mean square (RMS; [\%]) was analyzed within 200 ms after perturbation. Co-activation was quantified as ratio of antagonist (GM)/agonist (TA) EMG-RMS during unperturbed and perturbed walking. Time to onset was calculated (ms). Data were analyzed descriptively (mean +/- SD) followed by three-way-ANOVA (gender/condition/muscle; alpha= 0.05). Perturbed walking elicited higher EMG activity compared to normal walking for TA and PL in both genders (p < 0.000). RMS amplitude gender comparisons revealed an interaction between gender and condition (F = 4.6, p = 0.049) and, a triple interaction among gender, condition and muscle (F = 4.7, p = 0.02). Women presented significantly higher EMG-RMS [\%] PL amplitude than men during perturbed walking (mean difference = 209.6\%, 95\% confidence interval = -367.0 to -52.2\%, p < 0.000). Co-activation showed significant lower values for perturbed compared to normal walking (p < 0.000), without significant gender differences for both walking conditions. GM activated significantly earlier than TA and PL (p < 0.01) without significant differences between the muscle activation onsets of men and women (p = 0.7). The results reflect that activation strategies of the ankle encompassing muscles differ between genders. In provoked stumbling, higher PL EMG activity in women compared to men is present. Future studies should aim to elucidate if this specific behavior has any relationship with ankle injury occurrence between genders.},

The purpose of the present trial will be to compare four different intervention strategies of sensorimotor exercises that will result in improved trunk function. Methods/design: A single-blind, four-armed, randomized controlled trial with a 3-week (home-based) intervention phase and two measurement days pre and post intervention (M1/M2) is designed. Experimental procedures on both measurement days will include evaluation of maximum isokinetic and isometric trunk strength (extension/flexion, rotation) including perturbations, as well as neuromuscular trunk activity while performing strength testing. The primary outcome is trunk strength (peak torque). Neuromuscular activity (amplitude, latencies as a response to perturbation) serves as secondary outcome. The control group will perform a standardized exercise program of four sensorimotor exercises (three sets of 10 repetitions) in each of six training sessions (30 min duration) over 3 weeks. The intervention groups' programs differ in the number of exercises, sets per exercise and, therefore, overall training amount (group I: six sessions, three exercises, two sets; group II: six sessions, two exercises, two sets; group III: six sessions, one exercise, three sets). The intervention programs of groups I, II and III include additional perturbations for all exercises to increase both the difficulty and the efficacy of the exercises performed. Statistical analysis will be performed after examining the underlying assumptions for parametric and non-parametric testing. Discussion: The results of the study will be clinically relevant, not only for researchers but also for (sports) therapists, physicians, coaches, athletes and the general population who have the aim of improving trunk function.},

  abstract  = {Professionelle GT Langstreckenmotorsportler (Rennfahrer) m{\"u}ssen den hohen motorischen und kognitiven Anspr{\"u}chen ohne Verlust der Performance w{\"a}hrend eines Rennens endgegenwirken k{\"o}nnen. Sie m{\"u}ssen stets, bei hoher Geschwindigkeit fokussiert und konzentriert auf ihr Auto, die Rennstrecke und ihre Gegner reagieren k{\"o}nnen. Dar{\"u}ber hinaus sind Rennfahrer zus{\"a}tzlich durch die notwendige Kommunikation im Auto mit den Ingenieuren und Mechanikern in der Boxengasse gefordert. Daten {\"u}ber die tats{\"a}chliche Beanspruchung und h{\"a}ufig auftretende Beschwerden und/oder Verletzung von Profiathleten liegen kaum vor. F{\"u}r eine m{\"o}glichst gute Performance im Auto w{\"a}hrend eines Rennens ist es notwendige neben der k{\"o}rperlichen Beanspruchung auch die h{\"a}ufigen Krankheitsbilder zu kennen. Auf Basis dessen kann eine optimale Pr{\"a}vention oder notwendige Therapie zur m{\"o}glichst schnellen Reintegration in den Sport abgeleitet und entwickelt werden. Die vorliegende Arbeit befasst sich durch ein regelm{\"a}ßiges Gesundheitsmonitoring mit der Erfassung h{\"a}ufiger Beschwerden und oder Verletzungen im GT Langestreckenmotorsport zur Ableitung eines pr{\"a}ventiven (trainingstherapeutischen) und therapeutischen Konzeptes. Dar{\"u}ber hinaus, soll {\"u}ber die Einsch{\"a}tzung der k{\"o}rperlichen Leistungsf{\"a}higkeit der Athleten, auf Basis der Beanspruchung im Rennfahrzeug ein m{\"o}gliches Trainingskonzept in Abh{\"a}ngigkeit der Saison entwickelt werden. Insgesamt wurden {\"u}ber 15 Jahre (2003-2017) 37 m{\"a}nnliche Athleten aus dem GT Langstreckenmotorsport 353mal im Rahmen eines Gesundheitsmonitorings untersucht. Dabei wurden Athleten maximal 14 Jahre und mindestens 1 Jahr sportmedizinische betreut. Diese 2x im Jahr stattfindende Untersuchung beinhaltete im Wesentlichen eine sportmedizinische Untersuchung zur Einsch{\"a}tzung der Tauglichkeit f{\"u}r den Sport und die Erfassung der k{\"o}rperlichen Leistungsf{\"a}higkeit. {\"U}ber das Gesundheitsmonitoring hinaus erfolgte die Betreuung zus{\"a}tzlich an der Rennstrecke zur weiteren Erfassung der Beschwerden, Erkrankungen und Verletzungen der Athleten w{\"a}hrend ihrer sportartspezifischen Belastung. Zusammengefasst zeigen die Athleten geringe Pr{\"a}valenzen und Inzidenzen der Krankheitsbilder bzw. Beschwerden. Ein Unterschied der Pr{\"a}valenzen zeigt sich zwischen den Gesundheitsuntersuchungen und der Betreuung an der Rennstrecke. Die h{\"a}ufigsten Beschwerdebilder zeigen sich aus Orthop{\"a}die und Innerer Medizin. So sind Infekte der oberen Atemwege sowie Allergien neben Beschwerden der unteren Extremit{\"a}t und der Wirbels{\"a}ule am h{\"a}ufigsten. Demzufolge werden vorrangig physio- und trainingstherapeutische Konsequenzen abgeleitet. Eine medikament{\"o}se Therapie erfolgt im Wesentlichen w{\"a}hrend der Rennbetreuung. Zur Reduktion der orthop{\"a}dischen und internistischen Beschwerden sollten pr{\"a}ventive Maßnahmen mehr betont werden. Die k{\"o}rperliche Leistungsf{\"a}higkeit zeigt im Wesentlichen {\"u}ber die Untersuchungsjahre eine stabile Performance f{\"u}r die Ausdauer-, Kraft und sensomotorische Leistungsf{\"a}higkeit. Die Ausdauerleistungsf{\"a}higkeit kann in Abh{\"a}ngigkeit der Sportartspezifik mit einer guten bis sehr guten Auspr{\"a}gung definiert werden. Die Kraftleistungsf{\"a}higkeit und die sensomotorische Leistungsf{\"a}higkeit lassen sportartspezifische Unterschiede zu und sollte k{\"o}rpergewichtsbezogen betrachtet werden. Ein sportmedizinisches und trainingstherapeutisches Konzept m{\"u}sste demnach eine regelm{\"a}ßige {\"a}rztlich-medizinische Untersuchung mit dem Fokus der Orthop{\"a}die, Inneren Medizin und Hals- Nasen-Ohren-Kunde beinhalten. Dar{\"u}ber hinaus sollte eine regelm{\"a}ßige Erfassung der k{\"o}rperlichen Leistungsf{\"a}higkeit zur m{\"o}glichst effektiven Ableitung von Trainingsinhalten oder Pr{\"a}ventionsmaßnahmen ber{\"u}cksichtig werden. Auf Grundlage der hohen Reiset{\"a}tigkeit und der ganzj{\"a}hrigen Saison k{\"o}nnte ein 1-2x j{\"a}hrlich stattfindendes Trainingslager, im Sinne eines Grundlagen- und Aufbautrainings zur Optimierung der Leistungsf{\"a}higkeit beitragen, das Konzept komplementieren. Zudem scheint eine {\"a}rztliche Rennbetreuung notwendig.},

  abstract  = {The study investigated the incidence of Achilles and patellar tendinopathy in adolescent elite athletes and non-athletic controls. Furthermore, predictive and associated factors for tendinopathy development were analyzed. The prospective study consisted of two measurement days (M1/M2) with an interval of 3.2 +/- 0.9 years. 157 athletes (12.1 +/- 0.7 years) and 25 controls (13.3 +/- 0.6 years) without Achilles/patellar tendinopathy were included at Ml. Clinical and ultrasound examinations of both Achilles (AT) and patellar tendons (PT) were performed. Main outcome measures were incidence tendinopathy and structural intratendinous alterations (hypo-/hyperechogenicity, vascularization) at M2 [\%]. Incidence of Achilles tendinopathy was 1\% in athletes and 0\% in controls. Patellar tendinopathy was more frequent in athletes (13 \%)than in controls (4\%). Incidence of intratendinous alterations in ATs was 1-2\% in athletes and 0 \% in controls, whereas in PTs it was 4-6 \% in both groups (p >0.05). Intratendinous alterations at M2 were associated with patellar tendinopathy in athletes (p <= 0.01). Intratendinous alterations at M1, anthropometric data, training amount, sports or sex did not predict tendinopathy development (p>0.05). Incidence often dinopathy and intratendinous alterations in adolescent athletes is low in ATs and more common in PTs. Development of intratendinous alterations in PT is associated with tend in opathy. However, predictive factors could not be identified.},
