- Abstract
Promoting the use of inclusive instruction based on the tenets of Universal Design has occurred in the United States over the past three decades. In this study, a validated measure of university faculty attitudes toward inclusive instruction was translated from English to German and administered to a sample of faculty at a German institution. Responses (n=589) were subjected to an exploratory and confirmatory factor analysis in order to validate the translated items. The exploratory factor analysis yielded seven factors, which were very similar to the English version of the measure. The confirmatory factor analysis indicated the seven-factor solution showed acceptable model fit. Implications are discussed for universities both in the United States and abroad.

Aim of the study was to analyze the metabolic profile of badminton matches and training drills. Therefore, 11 male (23.2 ± 3.8 years, 182 ± 7 cm, 74.4 ± 8.4 kg) and five female (19.3 ± 1.5 years, 170 ± 6 cm, 62.6 ± 9.2 kg) elite badminton players participated in either a training match (TM; n = 7) and/or three protocols of multifeeding drills (T10, T30,T50;n = 13), that varied in interval and rest durations (10 s/10 s, 30 s/30 s, 50 s/50 s). Absolute and relative energetic costs (Wtot and Etot) and contribution to oxidative (WOxid), phosphagen (WPCr), and anaerobic glycolytic (WLa) metabolism were calculated by the three‐component PCr‐La‐O2‐method based on an indirect calorimetric approach from oxygen consumption during exercise, post exercise, and net blood lactate concentration. A novel intermittent approach was used to consider replenishment of phosphocreatine during each resting phase. Results show that during TM, Etot was 676 ± 98J·kg−1 min−1, while metabolic pathways contributed by 56.9 ± 8.6% (WOxid), 42.7 ± 8.7% (WPCr), and 0.4 ± 0.6% (WLa). In the multifeeding drills Etot was comparable between T10 (1020 ± 160J·kg−1 min−1) and T30 (985 ± 173 J·kg−1 min−1) but higher in T50 (1266 ± 194J·kg−1 min−1) (p < 0.001). Relative contribution of WOxid was lower in T10 (47.3 ± 7.7%) but similar in T30 (56.5 ± 6.2%) and T50 (57.3 ± 6.0%) (p < 0.001). WPCr was highest in T10 (51.1 ± 8.3%) followed by T30 (42.2 ± 6.9%) and lowest in T50 (31.2 ± 7.7%) (p < 0.001). WLa was similar between T10 (1.6 ± 1.0%) and T30 (2.1 ± 1.0%) but higher in T50 (11.6 ± 4.8%) (p < 0.001). Concludingly, metabolic costs in badminton are predominantly covered by oxidative and phosphagen energetic pathways. Metabolic profiles of the multifeeding drills differ depending on rally/interval duration, with increasing contribution of anaerobic glycolysis and decreasing phosphagen contribution in case of longer intervals. Plain Language Summary: Badminton stands out as a high‐paced and exceptionally demanding sport, necessitating a very complex interaction between the aerobic and anaerobic metabolic systems. Using an innovative approach of indirect caloric measurement, the main aim of the investigation was to determine the metabolic profiles of elite badminton match play and badminton‐specific training drills. Therefore, 16 elite players conducted either a training match and/or three different protocols of a multifeeding drill (with varying interval/rest durations). The study underscores a pivotal role of anaerobic alactic energy supply in badminton, highlighting the critical need for rapid phosphocreatine (PCr) replenishment to prevent performance decline attributed to increasing acidosis. While aerobic capacity remains vital for PCr replenishment, occasional reliance on lactic metabolism may be important in certain probable match deciding situations. The multifeeding drills exhibit variations in the metabolic profile depending on rally and rest durations. As the interval length increases, the dominance of aerobic and lactic metabolism rises, while the proportion of anaerobic alactic contribution decreases. Emphasizing that in on‐court drills different interval durations address different metabolic pathways, training content should be chosen wisely to accurately address individual training goals and to align with a long‐term training periodization perspective. Highlights: This is the first study using an intermittent approach of the three‐component PCr‐La‐O2‐method, to determine the metabolic profile of elite badminton match play and the impact of drill prescription on metabolic stress in badminton‐specific training drills.The present findings reveal that energy in badminton generally is predominantly derived from oxidative and phosphagen energetic pathways, with the anaerobic glycolytic system contributing only minimally.Multifeeding drills essentially mirror the metabolic demands of matches but exhibit variations depending on rally and rest periods. These findings underscore the need to select training protocols thoughtfully, tailor training according to individualized goals and to structure those goals within a long‐term training periodization.

The study explores the validity of the nonlinear index alpha 1 of detrended fluctuation analysis (DFAa1) of heart rate (HR) variability for exercise prescription in prolonged constant load running bouts of different intensities. 21 trained endurance athletes (9 w and 12 m) performed a ramp test for ventilatory threshold (vVT1 and vVT2) and DFAa1‐based (vDFAa1‐1 at 0.75 and vDFAa1‐2 at 0.5) running speed detection as well as two 20‐min running bouts at vDFAa1‐1 and vDFAa1‐2 (20‐vDFAa1‐1 and 20‐vDFAa1‐2), in which HR, oxygen consumption (VO2), respiratory frequency (RF), DFAa1, and blood lactate concentration [La‐] were assessed. 20‐vDFAa1‐2 could not be finished by all participants (finisher group (FG), n = 15 versus exhaustion group (EG), n = 6). Despite similar mean external loads of vDFAa1‐1 (10.6 ± 1.9 km/h) and vDFAa1‐2 (13.1 ± 2.4 km/h) for all participants compared to vVT1 (10.8 ± 1.7 km/h) and vVT2 (13.2 ± 1.9 km/h), considerable differences were present for 20‐vDFAa1‐2 in EG (15.2 ± 2.4 km/h). 20‐vDFAa1‐1 and 20‐DFAa1‐2 yielded significant differences in FG for HR (76.2 ± 5.7 vs. 86.4 ± 5.9 %HRPEAK), VO2 (62.1 ± 5.0 vs. 77.5 ± 8.6 %VO2PEAK), RF (40.6 ± 11.3 vs. 46.1 ± 9.8 bpm), DFA‐a1 (0.86 ± 0.23 vs. 0.60 ± 0.15), and [La‐] (1.41 ± 0.45 vs. 3.34 ± 2.24 mmol/L). Regarding alterations during 20‐vDFAa1‐1, all parameters showed small changes for all participants, while during 20‐vDFAa1‐2 RF and DFAa1 showed substantial alterations in FG (RF: 15.6% and DFAa1: −12.8%) and more pronounced in EG (RF: 20.1% and DFAa1: −35.9%). DFAa1‐based exercise prescription from incremental testing could be useful for most participants in prolonged running bouts, at least in the moderate to heavy intensity domain. In addition, an individually different increased risk of overloading may occur in the heavy to severe exercise domains and should be further elucidated in the light of durability and decoupling assessment. Highlights: DFAa1‐based exercise prescription from incremental testing shows potential for prolonged constant load exercise, at least in the moderate to heavy intensity domains for most trained runners.Caution is advised for the heavy to severe exercise domains as individual overload may occur.The relationship of DFAa1 and vDFAa1 seems to be highly individual as well as perspectives for the durability and decoupling assessment and should be further elucidated during longer exercise bouts.

Aim Measurements of Non-linear dynamics of heart rate variability (HRV) provide new possibilities to monitor cardiac autonomic activity during exercise under different environmental conditions. Using detrended fluctuation analysis (DFA) technique to assess correlation properties of heart rate (HR) dynamics, the present study examines the influence of normobaric hypoxic conditions (HC) in comparison to normoxic conditions (NC) during a constant workload exercise. Materials and Methods Nine well trained cyclists performed a continuous workload exercise on a cycle ergometer with an intensity corresponding to the individual anaerobic threshold until voluntary exhaustion under both NC and HC (15% O2). The individual exercise duration was normalized to 10% sections (10–100%). During exercise HR and RR-intervals were continuously-recorded. Besides HRV time-domain measurements (meanRR, SDNN), fractal correlation properties using short-term scaling exponent alpha1 of DFA were calculated. Additionally, blood lactate (La), oxygen saturation of the blood (SpO2), and rating of perceived exertion (RPE) were recorded in regular time intervals. Results We observed significant changes under NC and HC for all parameters from the beginning to the end of the exercise (10% vs. 100%) except for SpO2 and SDNN during NC: increases for HR, La, and RPE in both conditions; decreases for SpO2 and SDNN during HC, meanRR and DFA-alpha1 during both conditions. Under HC HR (40–70%), La (10–90%), and RPE (50–90%) were significantly-higher, SpO2 (10–100%), meanRR (40–70%), and DFA-alpha1 (20–60%) were significantly-lower than under NC. Conclusion Under both conditions, prolonged exercise until voluntary exhaustion provokes a lower total variability combined with a reduction in the amplitude and correlation properties of RR fluctuations which may be attributed to increased organismic demands. Additionally, HC provoked higher demands and loss of correlation properties at an earlier stage during the exercise regime, implying an accelerated alteration of cardiac autonomic regulation.

ddc:796 - Abstract
\(\bf Objective:\) In two independent study arms, we determine the effects of strength training (ST) and high-intensity interval training (HIIT) overload on cardiac autonomic modulation by measuring heart rate (HR) and vagal heart rate variability (HRV). \(\bf Methods:\) In the study, 37 well-trained athletes (ST: 7 female, 12 male; HIIT: 9 female, 9 male) were subjected to orthostatic tests (HR and HRV recordings) each day during a 4-day baseline period, a 6-day overload microcycle, and a 4-day recovery period. Discipline-specific performance was assessed before and 1 and 4 days after training. \(\bf Results:\) Following ST overload, supine HR, and vagal HRV (Ln RMSSD) were clearly increased and decreased (small effects), respectively, and the standing recordings remained unchanged. In contrast, HIIT overload resulted in decreased HR and increased Ln RMSSD in the standing position (small effects), whereas supine recordings remained unaltered. During the recovery period, these responses were reversed (ST: small effects, HIIT: trivial to small effects). The correlations between changes in HR, vagal HRV measures, and performance were weak or inconsistent. At the group and individual levels, moderate to strong negative correlations were found between HR and Ln RMSSD when analyzing changes between testing days (ST: supine and standing position, HIIT: standing position) and individual time series, respectively. Use of rolling 2–4-day averages enabled more precise estimation of mean changes with smaller confidence intervals compared to single-day values of HR or Ln RMSSD. However, the use of averaged values displayed unclear effects for evaluating associations between HR, vagal HRV measures, and performance changes, and have the potential to be detrimental for classification of individual short-term responses. \(\bf Conclusion:\) Measures of HR and Ln RMSSD during an orthostatic test could reveal different autonomic responses following ST or HIIT which may not be discovered by supine or standing measures alone. However, these autonomic changes were not consistently related to short-termchanges in performance and the use of rolling averages may alter these relationships differently on group and individual level.

ddc:610 - Abstract
The aim of this study was the analysis of incidence and type of injury in German elite powerlifters. A total of n = 57 competitive athletes of the German powerlifting federation completed a retrospective survey regarding acute andoveruse injuries. With 224 total injuries, a mean incidence of 1.51 per 1.000 h or 0.49 per year was calculated. Most injuries affected the lower back (20.5%), elbow (11.2%), pelvic region (10.3) and the shoulder (9.8%). Regarding the type of injury acute inflammation (25.9%), muscle strains/sprains (20.5%) and skin lesions (13%) dominated. The mean incidence significantly declined with increasing age and training experience of the athlete. Athletes using a bench press shirt and various regenerative methods like sauna or swimming also showed decreased injury rates. There was no significant correlation between body weight, height or gender and injury incidence. Compared to other sports, the incidence of injuries and overuse syndromes is still low in powerlifting. Nonetheless, appropriate strategies in training, equipment, prevention and regeneration should be employed to protect the athlete from injury.

Abstract Background Physical disability in multiple sclerosis (MS) is frequently characterized by impaired ambulation. Although walking tests have been successfully employed to assess walking ability in MS patients, data analytic procedures have predominantly relied on result-oriented parameters (e.g. total distance covered during a given amount of time), whereas process-oriented, dynamic walking patterns have mostly been ignored. This is striking, since healthy individuals have been observed to display a stereotypical U-shaped pattern of walking speed during timed walking, characterized by relatively high speed during the initial phase, subsequent slowing and final acceleration. Objective of the current study was to test the utility of the 6 min Walk (6MW) and the 12 min Walk (12MW) for revealing putatively abnormal temporal dynamic features of walking in MS. Methods A group of 37 MS patients was divided into subgroups with regard to their level of disability analyzed with the Expanded Disability Status Scale (EDSS; Mild MS Group, n = 20, EDSS 0 – 3.5; Moderate MS Group, n = 17, EDSS 4 – 5). Subsequently, both groups were compared to age-matched healthy controls (n = 25) on both tests with regard to result-oriented characteristics (mean walking speed), as well as dynamic features (mean decline in walking speed, degree of observed U-shape). Results Both MS groups showed a significantly lower mean walking speed than healthy controls, independent of test duration. Compared to controls, the Moderate MS Group also slowed down more rapidly throughout both tests. The same pronounced decline in walking speed was observed for the Mild MS Group in case of the 12MW. Additionally, for both MS groups an attenuated U-shaped velocity pattern was observed relative to controls in the 6MW. Patients' subjective fatigue scores were more strongly correlated with the decline in walking speed than with the common parameter of mean walking speed in the 6MW. Conclusions MS patients display abnormal dynamics in their walking patterns. A pronounced linear decline in walking speed can be identified with the 12MW even in MS patients with seemingly mild disability. Similarly, the 6MW can be used to assess an abnormal walking profile. Particularly the linear decline in walking speed on this test shows a more robust association with subjective fatigue than mean walking speed. Dynamic walking parameters may hence represent valuable clinical features, serving as surrogate measures of motor fatigue. Future studies are needed to verify their prognostic value.

Der vorliegende Bericht stellt den Test zur Erfassung fußballbezogener Kompetenzen bei Nachwuchsspielerinnen vor. Der „Soccer COmpetencies in Realistic Environments“-Test (kurz: SCORE) basiert auf der Beobachtung der Performanz während einer 4-gegen-4-Spielsituation. SCORE ist ein Instrument zur Talentdiagnostik im Nachwuchsbereich und wurde für Spielerinnen im Alter von acht bis 16 Jahren erfolgreich erprobt. Spielerinnen werden mittels SCORE in sieben Dimensionen bewertet. Diese Dimensionen bilden die technischen Kompetenzen und das Spielverständnis der Spielerinnen zuverlässig, objektiv und valide ab. SCORE ist für den Einsatz in der wissenschaftlichen Forschung ebenso gedacht wie für den Einsatz durch TrainerInnen bei ihren Vereinsspielerinnen. Mit SCORE können TrainerInnen ein individuelles Leistungsprofil ihrer Spielerinnen erstellen und ihre Trainingsplanung sowohl am Leistungsprofil des Teams als auch einzelner Spielerinnen ausrichten. Die besonderen Merkmale von SCORE sind: • Prozessorientierte Leistungsdiagnostik in spielnahen und realistischen Handlungssituationen • Zuverlässige Messung individueller Kompetenzen • Einfacher und zeitökonomischer Einsatz in Forschung und Trainingspraxis • Team- und individualbezogene Auswertung

The purpose of this study was to evaluate the metabolic profiles of athletes with different training specialization during the 30-15 intermittent fitness test (30-15
IFT ). Sixteen male handball players (HB) (age: 23 ± 3 yrs, height: 185 ± 7 cm, weight: 85 ± 14 kg) and 10 male endurance athletes (EA) (age: 26 ± 3 yrs, height: 178 ± 5 cm, weight: 69 ± 6 kg) completed the 30-15IFT , while oxygen uptake (VO2 ), heart rate (HR), and blood lactate were measured pre-, during, and 15 min post exercise. Metabolic energy, metabolic power, and relative energy contribution of the aerobic, anaerobic lactic, and anaerobic alactic system were calculated by the PCr-La-O2 method. Further, time above 90% of VO2peak was calculated. VO2peak , time above 90% VO2peak , VIFT, time to exhaustion, metabolic energy, and metabolic power were significantly lower in the HB players compared to the EA, while ΔBLC did not differ significantly between 2 Groups. Relative aerobic and anaerobic alactic energy shares did not differ significantly between 2 Groups while relative anaerobic lactic contribution was significantly higher in the handball players. Further, VO2 peak was significantly correlated with VIFT (r = .803) and time to exhaustion (r = .850). In conclusion, during intermittent endurance exercise training, specialization affects primarily relative anaerobic lactic energy contribution. [ABSTRACT FROM AUTHOR]- Published

Das Nachwuchsförderzentrum für Juniorinnen in Unterfranken fördert talentierte Nachwuchspielerinnen zwischen neun und 15 Jahren. Es ist bayernweit das einzige Nachwuchsförderzentrum nur für Spielerinnen, das über eine wissenschaftliche Begleitung im sportwissenschaftlichen und pädagogisch-psychologischen Bereich verfügt. Es wurde im Frühjahr 2014 von vier Partnervereinen in der Region gemeinsam mit der Empirischen Bildungsforschung und dem Sportzentrum der Universität Würzburg sowie dem 1. FC Nürnberg Mädchen- und Frauenfußball gegründet. Das Ziel ist es, talentierte Spielerinnen nach einem innovativen sportwissenschaftlichen Ansatz zu fördern und auf diese Weise die Chance des Übergangs in den Leistungssport für jede Spielerin zu erhöhen. Hierzu werden die Spielerinnen jedes Jahr im Frühsommer für acht Wochen während des wöchentlichen Trainings gesichtet und mittels allgemeiner motorischer Tests einerseits sowie fußballspezifischer Tests andererseits auf ihre Eignung für eine Aufnahme in das NFZ hin geprüft. Im sportartspezifischen Bereich wurden die Spielerinnen des Leistungskaders 2015/16 neben einem neu entwickelten Test, der die Fähigkeiten der Spielerinnen im Spielverlauf abbildet, auch mit Teilaufgaben der Testbatterie des Deutschen Fußball-Bundes konfrontiert (Höner & Roth, 2011, 2015). Dieser Test des DFB dient seit geraumer Zeit dazu, den Leistungsstand der an DFB-Stützpunkten geförderten Spielerinnen und Spieler zu überprüfen und durch den Vergleich mit Normwerttabellen individuelle SpielerInnen-Profile zu erstellen. Dieser Band berichtet die Ergebnisse der Leistungstests im NFZ für Juniorinnen nach den Kriterien des DFB und stellt die im NFZ entwickelte Leistungsdiagnostik NFZ-TestSpiel vor. Drei zentrale Befunde kristallisieren sich dabei heraus. Erstens nimmt die erste Generation der NFZ-Spielerinnen einen heterogenen Leistungsstand gemessen an den DFB-Kriterien ein. Dieser Befund relativiert sich aber zweitens, weil die Testbatterie des DFB durchaus Zweifel an deren Mess-Zuverlässigkeit aufkommen lässt und zudem Normwerte für Jahrgänge unterhalb der U11-Juniorinnen nicht existieren. Drittens erweist sich der im NFZ gewählte Ansatz vielversprechend, um die Spielfähigkeiten im Mädchenfußball über reale Spielsituationen, also als Prozessdiagnostik zu erfassen. Die vorgestellte NFZ-Leistungsdiagnostik erweist sich als in hohem Maße reliabel und ergibt erste Hinweise auf eine valide Messung individueller fußballspezifischer Kompetenzen.

In diesem Band werden die Bedingungen erfolgreicher Förderung von Mädchen im Breiten- und Leistungsfußball dargestellt. Den Schwerpunkt bilden motorische und psychsoziale Unterschiede bei Mädchen und Jungen ab der frühen Kindheit. Es handelt sich um einen Forschungsüberblick, in dem alle wissenschaftlichen Erkenntnisse zu körperlichen, sportlichen und psychosozialen Unterschiede zusammengefasst sind, die für den Breiten- und Leistungsfußball relevant sind. Dabei kann deutlich gemacht werden, dass der Mädchenfußball über teilweise völlig verschiedene Voraussetzungen verfügt als der Jungenfußball, die sich nicht nur auf motorische Fähigkeiten beziehen, sondern auch auf die bislang kaum beachtete Persönlichkeitsentwicklung von Mädchen und Jungen.

Background: Non-linear measures of heart rate variability (HRV) may provide new opportunities to monitor cardiac autonomic regulation during exercise. In healthy individuals, the HRV signal is mainly composed of quasi-periodic oscillations, but it also possesses random fluctuations and so-called fractal structures. One widely applied approach to investigate fractal correlation properties of heart rate (HR) time series is the detrended fluctuation analysis (DFA). DFA is a non-linear method to quantify the fractal scale and the degree of correlation of a time series. Regarding the HRV analysis, it should be noted that the short-term scaling exponent alpha1 of DFA has been used not only to assess cardiovascular risk but also to assess prognosis and predict mortality in clinical settings. It has also been proven to be useful for application in exercise settings including higher exercise intensities, non-stationary data segments, and relatively short recording times.Method: Therefore, the purpose of this systematic review was to analyze studies that investigated the effects of acute dynamic endurance exercise on DFA-alpha1 as a proxy of correlation properties in the HR time series.Results: The initial search identified 442 articles (351 in PubMed, 91 in Scopus), of which 11 met all inclusion criteria.Conclusions: The included studies show that DFA-alpha1 of HRV is suitable for distinguishing between different organismic demands during endurance exercise and may prove helpful to monitor responses to different exercise intensities, movement frequencies, and exercise durations. Additionally, non-linear DFA of HRV is a suitable analytical approach, providing a differentiated and qualitative view of exercise physiology. [ABSTRACT FROM AUTHOR]- Published

Background Physical disability in multiple sclerosis (MS) is frequently characterized by impaired ambulation. Although walking tests have been successfully employed to assess walking ability in MS patients, data analytic procedures have predominantly relied on result-oriented parameters (e.g. total distance covered during a given amount of time), whereas process-oriented, dynamic walking patterns have mostly been ignored. This is striking, since healthy individuals have been observed to display a stereotypical U-shaped pattern of walking speed during timed walking, characterized by relatively high speed during the initial phase, subsequent slowing and final acceleration. Objective of the current study was to test the utility of the 6 min Walk (6MW) and the 12 min Walk (12MW) for revealing putatively abnormal temporal dynamic features of walking in MS. Methods A group of 37 MS patients was divided into subgroups with regard to their level of disability analyzed with the Expanded Disability Status Scale (EDSS; Mild MS Group, n = 20, EDSS 0 – 3.5; Moderate MS Group, n = 17, EDSS 4 – 5). Subsequently, both groups were compared to age-matched healthy controls (n = 25) on both tests with regard to result-oriented characteristics (mean walking speed), as well as dynamic features (mean decline in walking speed, degree of observed U-shape). Results Both MS groups showed a significantly lower mean walking speed than healthy controls, independent of test duration. Compared to controls, the Moderate MS Group also slowed down more rapidly throughout both tests. The same pronounced decline in walking speed was observed for the Mild MS Group in case of the 12MW. Additionally, for both MS groups an attenuated U-shaped velocity pattern was observed relative to controls in the 6MW. Patients' subjective fatigue scores were more strongly correlated with the decline in walking speed than with the common parameter of mean walking speed in the 6MW. Conclusions MS patients display abnormal dynamics in their walking patterns. A pronounced linear decline in walking speed can be identified with the 12MW even in MS patients with seemingly mild disability. Similarly, the 6MW can be used to assess an abnormal walking profile. Particularly the linear decline in walking speed on this test shows a more robust association with subjective fatigue than mean walking speed. Dynamic walking parameters may hence represent valuable clinical features, serving as surrogate measures of motor fatigue. Future studies are needed to verify their prognostic value.
