Schluckst{\"o}rungen (Dysphagien) k{\"o}nnen in dieser Patientengruppe durch prim{\"a}re Sch{\"a}digungen des zentralen und peripheren neuronalen Netzwerkes der Schluckfunktion entstehen, aber auch bedingt durch die h{\"a}ufig l{\"a}ngere intensivmedizinische Behandlung und Beatmung. Erste klinische Befunde zeigen persistierende Dysphagien im Rahmen des Post-COVID-Syndroms („Long-COVID"), sodass die Patienten auch l{\"a}ngerfristige Maßnahmen zur Rehabilitation einer sicheren und suffizienten oralen Nahrungsaufnahme ben{\"o}tigen. Daher sollte in die Behandlung von COVID-19-Patienten ein strukturiertes erkrankungsspezifisches Monitoring in Bezug auf Dysphagiesymptome integriert werden, und atemtherapeutische Maßnahmen zur Regulation von Husteneffektivit{\"a}t und Atem-Schluck-Koordination sollten auch bei diesen Patienten essenzieller Bestandteil des Dysphagiemanagements sein.

An underdeveloped research area is the effect of unilateral stretching on non-local force output. Objective The objective of this review was to describe the effects of unilateral SS on contralateral, non-stretched, muscle force and identify gaps in the literature. Methods A systematic literature search following preferred reporting items for systematic review and meta-analyses Protocols guidelines was performed according to prescribed inclusion and exclusion criteria. Weighted means and ranges highlighted the non-local force output response to unilateral stretching. The physiotherapy evidence database scale was used to assess study risk of bias and methodological quality. Results Unilateral stretching protocols from six studies involved 6.3 +/- 2 repetitions of 36.3 +/- 7.4 s with 19.3 +/- 5.7 s recovery between stretches. The mean stretch-induced force deficits exhibited small magnitude effect sizes for both the stretched (-6.7 +/- 7.1\%, d = -0.35: 0.01 to -1.8) and contralateral, non-stretched, muscles (-4.0 +/- 4.9\%, d = , 0.22: 0.08 to 1.1). Control measures exhibited trivial deficits. Conclusion The limited literature examining non-local effects of prolonged SS revealed that both the stretched and contralateral, non-stretched, limbs of young adults demonstrate small magnitude force deficits. However, the frequency of studies with these effects were similar with three measures demonstrating deficits, and four measures showing trivial changes. These results highlight the possible global (non-local) effects of prolonged SS. Further research should investigate effects of lower intensity stretching, upper versus lower body stretching, different age groups, incorporate full warm-ups, and identify predominant mechanisms among others.}, language = {en} } @misc{BriniBenAbderrahmanClarketal.2021, author = {Brini, Seifeddine and Ben Abderrahman, Abderraouf and Clark, Cain C.

Methods: Twenty-four professional basketball players from the first Tunisian (Tunisia) division participated in this study. The players were dichotomized by sex (males [GM = 12]; females [GF = 12]). Both groups completed a 4 weeks SSGs training program with 3 sessions per week. Psychometric (e.g., quality of sleep, fatigue, stress, and delayed onset of muscle soreness [DOMS]) and physiological parameters (e.g., heart rate frequency, blood lactate) were measured during the first week (baseline) and at the end of RIF (post-test). Results: Post hoc tests showed a significant increase in stress levels in both groups (GM [- 81.11\%; p < 0.001, d = 0.33, small]; GF [- 36,53\%; p = 0.001, d = 0.25, small]). Concerning physiological parameters, ANCOVA revealed significantly lower heart rates in favor of GM at post-test (1.70\%, d = 0.38, small, p = 0.002). Conclusions: Our results showed that SSGs training at the end of the RIF negatively impacted psychometric parameters of male and female basketball players. It can be concluded that there are sex-mediated effects of training during RIF in basketball players, and this should be considered by researchers and practitioners when programing training during RIF.}, language = {en} } @article{BriniBenAbderrahmanClarketal.2021, author = {Brini, Seifeddine and Ben Abderrahman, Abderraouf and Clark, Cain C.

Fifteen men attended three laboratory sessions. Visit 1: lactate threshold, peak power output, and VO2max. Visits 2 and 3: Continuous (more fatiguing) and intermittent (less fatiguing) incremental cycling protocols [20\%, 40\%, 60\%, 80\% and 100\% of peak power output (PPO)]. During both protocols, multichannel EMG signals were recorded from vastus lateralis: muscle fiber conduction velocity (MFCV), instantaneous mean frequency (iMNF), and absolute and normalized root mean square (RMS) were analyzed. MFCV differed between protocols (P<0.001), and only increased consistently with power output during intermittent cycling. RMS parameters were similar between protocols, and increased linearly with power output. However, only normalized RMS was higher during the more fatiguing 100\% PPO stage of the continuous protocol [continuous-intermittent mean difference (95\% CI): 45.1 (8.5\% to 81.7\%)]. On the contrary, iMNF was insensitive to load changes and muscle fatigue (P=0.14). Despite similar power outputs, continuous and intermittent cycling influenced MFCV and normalized RMS differently. Only normalized RMS was sensitive to both increases in power output (in both protocols) and muscle fatigue, and thus is the most suitable EMG parameter to monitor changes in muscle activation during cycling.}, language = {en} }
