Whole-Body EMS Superimposed Walking and Nordic Walking on a Treadmill—Determination of Exercise Intensity to Conventional Exercise
Electrical muscle stimulation (EMS) is an increasingly popular training method and has become the focus of research in recent years. New EMS devices offer a wide range of mobile applications for whole-body EMS (WB-EMS) training, e.g., the intensification of dynamic low-intensity endurance exercises through WB-EMS. The present study aimed to determine the differences in exercise intensity between WB-EMS-superimposed and conventional walking (EMS-CW), and CON and WB-EMS-superimposed Nordic walking (WB-EMS-NW) during a treadmill test. Eleven participants (52.0 ± years; 85.9 ± 7.4 kg, 182 ± 6 cm, BMI 25.9 ± 2.2 kg/m2) performed a 10 min treadmill test at a given velocity (6.5 km/h) in four different test situations, walking (W) and Nordic walking (NW) in both conventional and WB-EMS superimposed. Oxygen uptake in absolute (VO2) and relative to body weight (rel. VO2), lactate, and the rate of perceived exertion (RPE) were measured before and after the test. WB-EMS intensity was adjusted individually according to the feedback of the participant. The descriptive statistics were given in mean ± SD. For the statistical analyses, one-factorial ANOVA for repeated measures and two-factorial ANOVA [factors include EMS, W/NW, and factor combination (EMS*W/NW)] were performed (α = 0.05). Significant effects were found for EMS and W/NW factors for the outcome variables VO2 (EMS: p = 0.006, r = 0.736; W/NW: p < 0.001, r = 0.870), relative VO2 (EMS: p < 0.001, r = 0.850; W/NW: p < 0.001, r = 0.937), and lactate (EMS: p = 0.003, r = 0.771; w/NW: p = 0.003, r = 0.764) and both the factors produced higher results. However, the difference in VO2 and relative VO2 is within the range of biological variability of ± 12%. The factor combination EMS*W/NW is statistically non-significant for all three variables. WB-EMS resulted in the higher RPE values (p = 0.035, r = 0.613), RPE differences for W/NW and EMS*W/NW were not significant. The current study results indicate that WB-EMS influences the parameters of exercise intensity. The impact on exercise intensity and the clinical relevance of WB-EMS-superimposed walking (WB-EMS-W) exercise is questionable because of the marginal differences in the outcome variables.

Gesundheitsmonitoring im Langstreckenmotorsport
Pre Participation Examination in Long distance Race car drivers
Professionelle GT Langstreckenmotorsportler (Rennfahrer) müssen den hohen motorischen und kognitiven Ansprüchen ohne Verlust der Performance während eines Rennens endgegenwirken können. Sie müssen stets, bei hoher Geschwindigkeit fokussiert und konzentriert auf ihr Auto, die Rennstrecke und ihre Gegner reagieren können. Darüber hinaus sind Rennfahrer zusätzlich durch die notwendige Kommunikation im Auto mit den Ingenieuren und Mechanikern in der Boxengasse gefordert. Daten über die tatsächliche Beanspruchung und häufig auftretende Beschwerden und/oder Verletzung von Profiathleten liegen kaum vor. Für eine möglichst gute Performance im Auto während eines Rennens ist es notwendige neben der körperlichen Beanspruchung auch die häufigen Krankheitsbilder zu kennen. Auf Basis dessen kann eine optimale Prävention oder notwendige Therapie zur möglichst schnellen Reintegration in den Sport abgeleitet und entwickelt werden. Die vorliegende Arbeit befasst sich durch ein regelmäßiges Gesundheitsmonitoring mit der Erfassung häufiger Beschwerden und oder Verletzungen im GT Langestreckenmotorsport zur Ableitung eines präventiven (trainingstherapeutischen) und therapeutischen Konzeptes. Darüber hinaus, soll über die Einschätzung der körperlichen Leistungsfähigkeit der Athleten, auf Basis der Beanspruchung im Rennfahrzeug ein mögliches Trainingskonzept in Abhängigkeit der Saison entwickelt werden.
Insgesamt wurden über 15 Jahre (2003-2017) 37 männliche 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 Einschätzung der Tauglichkeit für den Sport und die Erfassung der körperlichen Leistungsfähigkeit. Über das Gesundheitsmonitoring hinaus erfolgte die Betreuung zusätzlich an der Rennstrecke zur weiteren Erfassung der Beschwerden, Erkrankungen und Verletzungen der Athleten während ihrer sportartspezifischen Belastung. Zusammengefasst zeigen die Athleten geringe Prävalenzen und Inzidenzen der Krankheitsbilder bzw. Beschwerden. Ein Unterschied der Prävalenzen zeigt sich zwischen den Gesundheitsuntersuchungen und der Betreuung an der Rennstrecke. Die häufigsten Beschwerdebilder zeigen sich aus Orthopädie und Innerer Medizin. So sind Infekte der oberen Atemwege sowie Allergien neben Beschwerden der unteren Extremität und der Wirbelsäule am häufigsten. Demzufolge werden vorrangig physio- und trainingstherapeutische Konsequenzen abgeleitet. Eine medikamentöse Therapie erfolgt im Wesentlichen während der Rennbetreuung. Zur Reduktion der orthopädischen und internistischen Beschwerden sollten präventive Maßnahmen mehr betont werden. Die körperliche Leistungsfähigkeit zeigt im Wesentlichen über die Untersuchungsjahre eine stabile Performance für die Ausdauer-, Kraft und sensomotorische Leistungsfähigkeit. Die Ausdauerleistungsfähigkeit kann in Abhängigkeit der Sportartspezifik mit einer guten bis sehr guten Ausprägung definiert werden. Die Kraftleistungsfähigkeit und die sensomotorische Leistungsfähigkeit lassen sportartspezifische Unterschiede zu und sollte körpergewichtsbezogen betrachtet werden.
Ein sportmedizinisches und trainingstherapeutisches Konzept müsste demnach eine regelmäßige ärztlich-medizinische Untersuchung mit dem Fokus der Orthopädie, Inneren Medizin und Hals- Nasen-Ohren-Kunde beinhalten. Darüber hinaus sollte eine regelmäßige Erfassung der körperlichen Leistungsfähigkeit zur möglichst effektiven Ableitung von Trainingsinhalten oder Präventionsmaßnahmen berücksichtig werden. Auf Grundlage der hohen Reisetätigkeit und der ganzjährigen Saison könnte ein 1-2x jährlich stattfindendes Trainingslager, im Sinne eines Grundlagen- und Aufbautrainings zur Optimierung der Leistungsfähigkeit beitragen, das Konzept komplementieren. Zudem scheint eine ärztliche Rennbetreuung notwendig.
Professional long distance race car drivers (GT- Sportscars) are highly challenged regarding physical load during racing without any lost of performance. It is needed that those athletes are able to react in time in addiction to high speed and other race car drivers on the track. Studies about common injuries or overuse are rare and not longitudinal analysed. Based on known sports specific injuries or overuse, necessary prevention strategies or therapy concept are helpful for an evident Return to Sport. This study is based on prospective longitudinal Analyses of common injuries and overuse in professional race car drivers with differentiation to prevention and therapeutic concepts. Additionally, based on physical capacity (endurance, strength, sensorymotor- control) a needed training recommendation is derived. Overall 37 male professional longdistance race car drivers were analysed over 15 years (2003-2017). Therefore 353 preparticipation examinations (PPE) and physical fitness tests were included. The number of Athletes ranged between 6-19 per year with a support from 1 to 15 years. Additionally to the PPE and physical fitness tests the needed medical care at the track during race were analysed for the years 2015 and 2016.
Summarized, longdistance race car drivers are showing low Prevalence’s of injuries or overuse. Frequent complaints are infections of the upper respiratory tract, allergies and tendinopathy of the lower limb together with chronic unspecific low back pain. The therapeutic derivation on track was for the most part drug-treated. A useful consequence for the reduction of the common orthopedic and internistic complaints are preventive methods like aerobic endurance training, sleep hygiene, (eccentric) strength training and balance training. The physical capacite is stable over the years. The endurance capacity shows in dependence to the sports specific a good capacity. The strength and sensorymotor control capacity shows sports specific differences.
A sports medical and preventive/ therapeutic concept in longdistance motorsports has to include regular PPE with focus on orthopedic and internistic examinations. Additionally a regularly measurement of the physical capacity (endurance, strength and sensorymotor control) is needed for evident and individual recommendations for training and prevention. Regarding the high all year intercontinental travelling and the season over the whole year a 1-2 times organized fitness camp could compliment a sports medical concept as well as medical care on the track.

Intraindividual Doppler Flow Response to Exercise Differs Between Symptomatic and Asymptomatic Achilles Tendons
Objective: This study investigated intraindividual differences of intratendinous blood flow (IBF) in response to running exercise in participants with Achilles tendinopathy.
Design: This is a cross-sectional study.
Setting: The study was conducted at the University Outpatient Clinic.
Participants: Sonographic detectable intratendinous blood flow was examined in symptomatic and contralateral asymptomatic Achilles tendons of 19 participants (42 ± 13 years, 178 ± 10 cm, 76 ± 12 kg, VISA-A 75 ± 16) with clinically diagnosed unilateral Achilles tendinopathy and sonographic evident tendinosis.
Intervention: IBF was assessed using Doppler ultrasound “Advanced Dynamic Flow” before (Upre) and 5, 30, 60, and 120 min (U5–U120) after a standardized submaximal constant load run.
Main Outcome Measure: IBF was quantified by counting the number (n) of vessels in each tendon.
Results: At Upre, IBF was higher in symptomatic compared with asymptomatic tendons [mean 6.3 (95% CI: 2.8–9.9) and 1.7 (0.4–2.9), p < 0.01]. Overall, 63% of symptomatic and 47% of asymptomatic Achilles tendons responded to exercise, whereas 16 and 11% showed persisting IBF and 21 and 42% remained avascular throughout the investigation. At U5, IBF increased in both symptomatic and asymptomatic tendons [difference to baseline: 2.4 (0.3–4.5) and 0.9 (0.5–1.4), p = 0.05]. At U30 to U120, IBF was still increased in symptomatic but not in asymptomatic tendons [mean difference to baseline: 1.9 (0.8–2.9) and 0.1 (-0.9 to 1.2), p < 0.01].
Conclusion: Irrespective of pathology, 47–63% of Achilles tendons responded to exercise with an immediate acute physiological IBF increase by an average of one to two vessels (“responders”). A higher amount of baseline IBF (approximately five vessels) and a prolonged exercise-induced IBF response found in symptomatic ATs indicate a pain-associated altered intratendinous “neovascularization.”

General versus sports-specific injury prevention programs in athletes
Introduction
Injury prevention programs (IPPs) are an inherent part of training in recreational and professional sports. Providing performance-enhancing benefits in addition to injury prevention may help adjust coaches and athletes’ attitudes towards implementation of injury prevention into daily routine. Conventional thinking by players and coaches alike seems to suggest that IPPs need to be specific to one’s sport to allow for performance enhancement. The systematic literature review aims to firstly determine the IPPs nature of exercises and whether they are specific to the sport or based on general conditioning. Secondly, can they demonstrate whether general, sports-specific or even mixed IPPs improve key performance indicators with the aim to better facilitate long-term implementation of these programs?
Methods
PubMed and Web of Science were electronically searched throughout March 2018. The inclusion criteria were randomized control trials, publication dates between Jan 2006 and Feb 2018, athletes (11–45 years), injury prevention programs and included predefined performance measures that could be categorized into balance, power, strength, speed/agility and endurance. The methodological quality of included articles was assessed with the Cochrane Collaboration assessment tools.
Results
Of 6619 initial findings, 22 studies met the inclusion criteria. In addition, reference lists unearthed a further 6 studies, making a total of 28. Nine studies used sports specific IPPs, eleven general and eight mixed prevention strategies. Overall, general programs ranged from 29–57% in their effectiveness across performance outcomes. Mixed IPPs improved in 80% balance outcomes but only 20–44% in others. Sports-specific programs led to larger scale improvements in balance (66%), power (83%), strength (75%), and speed/agility (62%).
Conclusion
Sports-specific IPPs have the strongest influence on most performance indices based on the significant improvement versus control groups. Other factors such as intensity, technical execution and compliance should be accounted for in future investigations in addition to exercise modality.

Validity of isokinetic trunk measurements with respect to healthy adults, athletes and low back pain patients
Background: Isokinetic measurements are widely used to assess strength capacity in a clinical or research context. Nevertheless, the validity of isokinetic measures for identifying strength deficits and the evaluation of therapeutic process regarding different pathologies is yet to be established. Therefore, the purpose of this review is to evaluate the validity of isokinetic measures in a specific case: that of muscular capacity in low back pain (LBP).
Methods: A literature search (PubMed; ISI Web of Knowledge; The Cochrane Library) covering the last 10 years was performed. Relevant papers regarding isokinetic trunk strength measures in healthy and patients with low back pain (PLBP) were searched. Peak torque values [Nm] and peak torque normalized to body weight [Nm/kg BW] were extracted for healthy and PLBP. Ranked mean values across studies were calculated for the concentric peak torque at 60 degrees/s as well as the flexion/extension (F/E) ratio.
Results: 34 publications (31 flexion/extension; 3 rotation) were suitable for reporting detailed isokinetic strength measures in healthy or LBP (untrained adults, adolescents, athletes). Adolescents and athletes were different compared to normal adults in terms of absolute trunk strength values and the F/E ratio. Furthermore, isokinetic measures evaluating therapeutic process and isokinetic rehabilitation training were infrequent in literature (8 studies).
Conclusion: Isokinetic measurements are valid for measuring trunk flexion/extension strength and F/E ratio in athletes, adolescents and (untrained) adults with/without LBP. The validity of trunk rotation is questionable due to a very small number of publications whereas no reliable source regarding lateral flexion could be traced. Therefore, isokinetic dynamometry may be utilized for identifying trunk strength deficits in healthy adults and PLBP.

Trunk Muscle Activity during Drop Jump Performance in Adolescent Athletes with Back Pain
In the context of back pain, great emphasis has been placed on the importance of trunk stability, especially in situations requiring compensation of repetitive, intense loading induced during high-performance activities, e.g., jumping or landing. This study aims to evaluate trunk muscle activity during drop jump in adolescent athletes with back pain (BP) compared to athletes without back pain (NBP). Eleven adolescent athletes suffering back pain (BP: m/f: n = 4/7; 15.9 +/- 1.3 y; 176 +/- 11 cm; 68 +/- 11 kg; 12.4 +/- 10.5 h/we training) and 11 matched athletes without back pain (NBP: m/f: n = 4/7; 15.5 +/- 1.3 y; 174 +/- 7 cm; 67 +/- 8 kg; 14.9 +/- 9.5 h/we training) were evaluated. Subjects conducted 3 drop jumps onto a force plate (ground reaction force). Bilateral 12-lead SEMG (surface Electromyography) was applied to assess trunk muscle activity. Ground contact time [ms], maximum vertical jump force [N], jump time [ms] and the jump performance index [m/s] were calculated for drop jumps. SEMG amplitudes (RMS: root mean square [%]) for all 12 single muscles were normalized toMIVC (maximum isometric voluntary contraction) and analyzed in 4 time windows (100 ms pre- and 200 ms post-initial ground contact, 100 ms pre- and 200 ms post-landing) as outcome variables. In addition, muscles were grouped and analyzed in ventral and dorsal muscles, as well as straight and transverse trunk muscles. Drop jump ground reaction force variables did not differ between NBP and BP (p > 0.05). Mm obliquus externus and internus abdominis presented higher SEMG amplitudes (1.3-1.9-fold) for BP (p < 0.05). Mm rectus abdominis, erector spinae thoracic/lumbar and latissimus dorsi did not differ (p > 0.05). The muscle group analysis over the whole jumping cycle showed statistically significantly higher SEMG amplitudes for BP in the ventral (p = 0.031) and transverse muscles (p = 0.020) compared to NBP. Higher activity of transverse, but not straight, trunk muscles might indicate a specific compensation strategy to support trunk stability in athletes with back pain during drop jumps. Therefore, exercises favoring the transverse trunk muscles could be recommended for back pain treatment.
