“…The interaction effects of music tempo and exercise intensity on MF RF and MF VM differences were also not significant ( p > 0.05) and both effect sizes were small (0 < effect size d < 0.5). Meanwhile, the experimental results for the differences in MF were negative, which indicates decreased local muscle fatigue after running, which is inconsistent with the results of most previous studies that used the difference in MF as an indicator [ 56 , 57 ]. The reason may be due to the different distribution patterns of fast and slow muscle fibers in different individuals and muscles, which are genetically determined and almost impossible to change later by exercise [ 58 ].…”

Background: This study aimed to clarify the effect of music tempo on runners’ perception of fatigue at different exercise intensities and while listening to music of different tempos through running experiments. Methods: This study used a within-subject two-factor experimental design with music tempo (fast music, slow music, no music) and exercise intensity (high intensity, low intensity) as independent variables and the time to fatigue perception (TFP), the difference in heart rate (HR) and the difference in the median frequency (MF) of surface electromyography (sEMG) signals as observation indexes. Eighteen participants completed a total of 108 sets of running experiments. Results: (1) The main effect of music tempo on the TFP was significant (p < 0.001). (2) The main effect of exercise intensity on the TFP was significant (p < 0.001), and the main effect on the difference in HR was significant (p < 0.001). (3) The interaction effect of music tempo and exercise intensity on the TFP was significant (p < 0.05). Conclusions: Exercisers’ subjective perception of fatigue was affected by music tempo and the interaction between music tempo and exercise intensity, and exercisers’ objective fatigue perception was influenced mostly by exercise intensity. The findings of this study provide guidance for runners’ choice of music at different intensities of exercise. Whether it is low-intensity exercise or high-intensity exercise, listening to fast music while exercising can help runners perform better mentally and physically during their runs.

“…Previous experimental studies have shown that a repeated exercise bout of an rotator cuff muscles exercise led to an acute alteration of increased supraspinatus tendon thickness (McCreesh et al, 2017;Klich et al, 2020). Similarly, a short exercise bout in overhead athletes (Klich et al, 2020;Porter et al, 2020), and longer term repetitive work activity (Pozzi et al, 2021) have led to an increase in supraspinatus tendon thickness. An increase in muscle stiffness has also been demonstrated after repetitive upper extremity activity of the pectoralis major, deltoid, infraspinatus and upper trapezius (Dashottar et al, 2014;Klich et al, 2020).…”

This study aimed to investigate the acute effect of repeated climbing actions on functional and morphological measures of the shoulder girdle. Fifteen male indoor climbers participated in this study.All the climbers declared route level 6a+, as the best climbing grade (French climbing grade scale).Functional (range of motion -ROM and muscle strength), and morphological measurements (muscle/tendon stiffness and thickness) after a repeated climbing exercise protocol were analyzed. The ROM and muscle strength showed significant decreases from baseline to Immediate-Post (IA) as well as significant increases from IA to 1h-Post for all movements (p ≤.001 for all). Muscle stiffness showed significant increases from baseline to IA after as well as significant decreases from IA to 1h-Post for all muscles (p ≤.001 for all). However, thickness showed significant increases from baseline to IA for supraspinatus tendon and muscle thickness and occupation ratio (p ≤.001 for all), while a significant decrease was observed in acromiohumeral distance (p ≤.001). Significant decreases from IA to 1h-Post were found for muscles/tendons and occupation ratio (p ≤.001 f or all), while a significant increase for AHD (p ≤.001). Our data demonstrated acute alterations in tendon thickness due to acute signs of implement symptom in climbers.

“…While previous research studies have focussed on functional movements in injured populations, 18,20 several more-recent studies have investigated the impact of fatigue in overhead athletes, [21][22][23] during movement assessment of athletes with and without shoulder injury 24 and preventative/ rehabilitative exercises. [25][26][27][28] However, there is a lack of information relating to utilising functional tests to assess muscle activity during controlled, non-skilled everyday tasks.…”

Background A strong body of literature has been published outlining muscle activity differences during sports performance in groups of overhead athletes. However, there are limited studies that have directly compared the muscle activity in overhead athletes with and without history of shoulder injury during functional everyday tasks. Purpose This study aimed to identify muscle activities across fourteen upper extremity and core muscles during three functional everyday movements in athletes with and without history of shoulder injury. Study Design Cross-Sectional Study Methods Thirty-two male overhead throwing athletes (fifteen healthy and seventeen injured) were recruited and completed three everyday functional movements of high elevation, low elevation, and rotation, using their dominant arm to move an object between two fixed positions. Electromyography (EMG) was recorded for fourteen muscles including: biceps brachii, deltoids (anterior, medial, and posterior), trapezius (upper and lower), pectoralis major, latissimus dorsi, serratus anterior, infraspinatus, external obliques, and gluteus maximus (all surface electrodes) and supraspinatus (fine wire electrode). Mixed model repeated measures ANOVA and post-hoc analysis assessed mean muscle activity (%MVC) between groups and each movement phase. Results Upper trapezius elicited higher mean activity in healthy athletes during both phases of the arm rotation task (p < 0.05). No differences between groups were evident for arm elevation tasks. Qualitative analysis of muscle patterns during functional tasks reflected a temporal shift in muscle activation timings and magnitudes between athlete groups, suggesting potential compensatory mechanisms in injured athletes. Conclusion Injured overhead athletes appear to utilize other upper limb and shoulder girdle muscles to compensate for lower upper trapezius activity during functional everyday tasks.
