“…For instance, Howard et al. () investigated the effects of back extensor fatigue on jump performance and neuromuscular performance during CMJ and lateral jumps on unstable (i.e., AIREX® balance pad) compared with stable surface in healthy males (23 ± 5 years). Their study revealed no main effect of surface instability on measures of CMJ performance.…”

“…The elite volleyball players were recruited from volleyball clubs competing in the third (n = 1), second (n = 17), or first (n = 2) division of the German Volleyball Association. An a priori power analysis (Faul et al, 2007) with an assumed type 1 error of 0.05 and a type 2 error rate of 0.20 (80% statistical power) was conducted for measures of CMJ performance (Howard et al, 2015). The analysis revealed that 20 subjects would be sufficient for finding a statistically significant main effect for the factor fatigue (i.e., nonfatigued vs fatigued) and/or surface (i.e., stable vs unstable surface).…”

“…In particular in volleyball, different artificial (e.g., balance pad) or natural unstable surfaces (e.g., sand, grass) change movement conditions and demands for athletic performance. So far, only few studies investigated the effects of unstable surface conditions during DJs and CMJs (Arampatzis et al, 2004;Prieske et al, 2013;Howard et al, 2015). Recently, Prieske et al (2013) examined the effects of surface instability (i.e., AIREX® balance pad) on DJ performance in healthy male and female young adults (23 ± 3 years).…”

“…Besides the discrepancy between the effects on surface instability on DJ performance, inconsistency was also found in the literature for CMJ performance on unstable compared with stable surfaces. For instance, Howard et al (2015) investigated the effects of back extensor fatigue on jump performance and neuromuscular performance during CMJ and lateral jumps on unstable (i.e., AIREX® balance pad) compared with stable surface in healthy males (23 ± 5 years).

“…() found lower jump heights when DJs were performed on a foam balance pad compared with stable condition. Moreover, when performing CMJs on the same balance pad, no performance differences were observed between unstable and stable conditions (Howard et al., ). Task and surface specific effects were also found for lower limb muscle activities during jumping and landing on stable as compared with unstable surfaces.…”

It has previously been shown that fatigue and unstable surfaces affect jump performance. However, the combination thereof is unresolved. Thus, the purpose of this study was to examine the effects of fatigue and surface instability on jump performance and leg muscle activity. Twenty elite volleyball players (18 ± 2 years) performed repetitive vertical double-leg box jumps until failure. Before and after a fatigue protocol, jump performance (i.e., jump height) and electromyographic activity of selected lower limb muscles were recorded during drop jumps (DJs) and countermovement jumps (CMJs) on a force plate on stable and unstable surfaces (i.e., balance pad on top of force plate). Jump performance (3-7%; P < 0.05; 1.14 ≤ d ≤ 2.82), and muscle activity (2-27%; P < 0.05; 0.59 ≤ d ≤ 3.13) were lower following fatigue during DJs and CMJs, and on unstable compared with stable surfaces during DJs only (jump performance: 8%; P < 0.01; d = 1.90; muscle activity: 9-25%; P < 0.05; 1.08 ≤ d ≤ 2.54). No statistically significant interactions of fatigue by surface condition were observed. Our findings revealed that fatigue impairs neuromuscular performance during DJs and CMJs in elite volleyball players, whereas surface instability affects neuromuscular DJ performance only. Absent fatigue × surface interactions indicate that fatigue-induced changes in jump performance are similar on stable and unstable surfaces in jump-trained athletes.

the aim of this study was to investigate the size of the change and asymmetry in fatigability of gluteus maximus muscles during endurance training in short-track. the research has taken into account the position of athletes during skating and the problem of fatigue and pain in these muscles. the research covered involved eight female athletes of the polish national team in short track, which had been prepared to the olympic Games in pyeongchang. the surface electromyography (seMG) system was used to measure fatigue of right and left gluteus maximus muscles, in the modified Biering-Sorensen test. The test was conducted five times during the training: before training, after warmup, and after each of 3 series of the endurance training. Comparing the mean frequency of the surface electromyography power spectrum of the test, statistically significant reduction of the average frequency value of the right muscle from 55.61 ± 7.08 to 48.64 ± 4.48 Hz and left muscle from 58.78 ± 4.98 to 53.18 ± 4.62 Hz was reported, which prove the muscle fatigue. In subsequent series tests, the sEMG signal frequency of begin decrease more than the end of the each measurement, which determines the fatigue threshold. The size of the d Cohen effect in fatigue drops along with subsequent five tests during the training. Skaters has higher frequency reduction of the right lower limb, which indicates its greater fatigue during skateing. the fatigue and asymmetry in muscle observed in short-track has implications for training and performance. Speed skating has two disciplines that differ in track length and skating technique. In short track, the distance of one lap is 111 m, which is less than one third of the skating track on a long track (400 m). Such a short distance forces the competitors to go along an oval track with high speed and small turn radiuses. During a race at a distance of 1,000 m the short track competitor, when turning, generates twice as large forces as on a long track 1. In order to obtain the best possible result in short track, a successful athlete should reduce his fatiguability. In addition, what also matters are the race tactics, psychological and technical aspects, maximum voluntary contraction force, reaction time and the quality of lower limb muscle coordination 2-4. General body fatigue can affect psychological and physiological aspects. One of the factors of physiological fatigue is muscle fatigue, which is defined as reduction in muscle capacity to perform work, after prior physical effort 5,6. Local muscle fatigue is concentrated mainly on a decrease in contraction force, that is inability of the muscle to generate proper capacity 7. This is an inevitable process, and attempts to reduce it are constantly made. In the literature analysing muscle fatigue, many variants of this process can be found 8 , which also uses surface electromyography and analysis of the sEMG signal frequency of the power spectrum. This method provides useful information on local muscle fatigue 9-12. When the muscle fatigue increases, the num...
