“…The limit of a subject’s endurance during the IME test, that is, the point at which the subject is unwilling or unable to continue repetitive contractions, has been referred to as the point of ‘exhaustion’, ‘the limit of tolerance’, or the point of ‘fatigue’ 4 , 5 . I n this study, two of the same mechanical manifestations of muscle fatigue found in previous studies were observed: one was a significant difference in power output between the first five repetitions and the last five repetitions, and the other was a progressive decrease of power output as the number of repetitions increased 1 , 14 , 39 , 59 . T herefore, by keeping all of the variables consistent except for time, muscular endurance can be measured by considering the amount of work produced or the activity duration via the recommended IME testing protocol in this study.…”

“…Most human activities such as sports, industrial tasks, and daily living activities require dynamic endurance because most muscles are required to work continuously to accomplish these activities 1 – 3 . The limit of human endurance during a physical task is usually decided by the point at which an individual is unwilling or unable to continue the physical task, and this point is referred to as the point of ‘exhaustion’ or ‘fatigue’ 4 , 5 .…”

The limit of dynamic endurance during repetitive contractions has been referred to as the point of muscle fatigue, which can be measured by mechanical and electrophysiological parameters combined with subjective estimates of load tolerance for revealing the human real-world capacity required to work continuously. In this study, an isotonic muscular endurance (IME) testing protocol under a psychophysiological fatigue criterion was developed for measuring the retentive capacity of the power output of lower limb muscles. Additionally, to guide the development of electrophysiological evaluation methods, linear and non-linear techniques for creating surface electromyography (sEMG) models were compared in terms of their ability to estimate muscle fatigue. Forty healthy college-aged males performed three trials of an isometric peak torque test and one trial of an IME test for the plantar flexors and knee and hip extensors. Meanwhile, sEMG activity was recorded from the medial gastrocnemius, lateral gastrocnemius, vastus medialis, rectus femoris, vastus lateralis, gluteus maximus, and biceps femoris of the right leg muscles. Linear techniques (amplitude-based parameters, spectral parameters, and instantaneous frequency parameters) and non-linear techniques (a multi-layer perception neural network) were used to predict the time-dependent power output during dynamic contractions. Two mechanical manifestations of muscle fatigue were observed in the IME tests, including power output reduction between the beginning and end of the test and time-dependent progressive power loss. Compared with linear mapping (linear regression) alone or a combination of sEMG variables, non-linear mapping of power loss during dynamic contractions showed significantly higher signal-to-noise ratios and correlation coefficients between the actual and estimated power output. Muscular endurance required in real-world activities can be measured by considering the amount of work produced or the activity duration via the recommended IME testing protocol under a psychophysiological termination criterion. Non-linear mapping techniques provide more powerful mapping of power loss compared with linear mapping in the IME testing protocol.

“…Various sensors are processed for multilevel and multispace information complementation and optimized combination processing, and finally, a consistent interpretation of the observation environment is produced. In this process, it is necessary to make full use of multisource data for reasonable control and use, and the ultimate goal of information fusion is to derive more useful information through the multilevel and multifaceted combination of information based on the separated observation information obtained by each sensor [ 10 ]. This not only takes advantage of the cooperative operation of multiple sensors but also comprehensively processes data from other information sources to improve the intelligence of the entire sensor system, as shown in Figure 1 .…”

For athletes of different sports, their muscle activities in different sports will show different special characteristics according to different sports. The purpose of this paper is to study the technology of multi-information fusion and to study the athletes of the long jump competition. The relevant research on the muscle specific ability test methods of the athletes in the long jump competition is of great significance to the study of the long jump. This paper proposes a long jumper’s special muscle ability experiment, using the now very popular multi-information fusion technology, to conduct in-depth research on the biomechanics of the long jumper’s special ability of the take-off muscle, which can provide an effective scientific basis for the special ability level and special strength of the long jumper’s take-off sports. The results of the study show that the hip joint of the take-off leg produces greater hip extensor torque during the take-off action of long jump, and the active contraction ability of the knee flexor group is very important for taking off and avoiding damage to the posterior femoral muscle group. The change range of the pressure center is between 51.26% and 74.35%, which has great application value in actual training.

“…Although the therapeutic benefits of KT in clinical practice have been reported [ 17 – 21 ], several recent studies suggest no significant effects of KT on lower limb function, muscle strength, power, and self-perceived fatigue level in clinical practice [ 22 , 23 ]. Some studies have addressed the effects of screwing on forearm muscle strength and fatigue [ 8 – 10 , 12 , 13 , 24 – 26 ]. Based on our literature search, few have examined the effect of KT on the strength and muscle fatigue for forearm supination/pronation activities.…”

Background Repetitive exertion in supination/pronation could increase the risk of forearm diseases due to fatigue. Kinesio taping (KT) is a physical therapy technique that decreases muscle tone and musculoskeletal disorders (MSDs) risk. Many assumptions about taping have been made and several studies have considered the taping applications; however, the effect of KT on strength and fatigue of the forearm supination/pronation remains unclear. The purpose of this study was to evaluate the effect of KT on forearm performance fatigability. Methods A screwing test was constructed to measure the forearm force loss and screwing efficiency during repetitive supination/pronation. Data from 18 healthy adults who underwent both KT and no taping (NT) sessions were used to investigate the forearm strength change in terms of grip force (GF), driving torque (DT), and push force (PF). The maximal isometric forces before and after the screwing test and force decreasing rate (efficiency) during screwing were evaluated to assess the performance fatigability in KT and NT conditions. Results A statistically significant force loss (FL) in maximal isometric GF (p = 0.039) and maximal isometric DT (p = 0.044); however, no significant difference was observed in maximal isometric PF (p = 0.426) between NT and KT. KT provides greater screwing efficiency than NT. Conclusions KT could not improve FL in the maximal muscle strength of the forearm in healthy subjects. KT on the forearm was associated with a lesser decline in DT efficiency than NT, implying that KT could decrease the loss rate of muscle strength and delay the development of fatigue; however, the KT did not yield improvements in PF while performing screwing tasks.
