“…Our previous research showed a positive relationship between perceived and performance fatigability in the final stage of the activity differences and significant changes in mA, which revealed the presence of upper limb motion in the sagittal plane and an overall increase in movement variability, with sex-related differences 20,21 . This study aimed to examine the relationship between PcFat and upper limb kinematic behavior during a ULPSIT.…”

SUMMARY OBJECTIVE: The objective of this study was to investigate the relationship between upper limb kinetics and perceived fatigability in elderly individuals during an upper limb position sustained isometric task. METHODS: A total of 31 elderly participants, 16 men (72.94±4.49 years) and 15 women (72.27±6.05 years), performed a upper limb position sustained isometric task. Upper-limb acceleration was measured using an inertial measurement unit. Perceived fatigability was measured using the Borg CR10 scale. RESULTS: Higher mean acceleration in the x-axis throughout the activity was associated with higher final perceived fatigability scores. Moderate correlations were observed between perceived fatigability variation and mean acceleration cutoffs in all axes during the second half of the activity. In women, significant correlations were found between all perceived fatigability cutoffs and mean acceleration in the y- and x-axes. However, in men, the relationships between perceived fatigability variation and mean acceleration were more extensive and stronger. CONCLUSION: The acceleration pattern of the upper limb is linked to perceived fatigability scores and variation, with differences between sexes. Monitoring upper limb acceleration using a single inertial measurement unit can be a useful and straightforward method for identifying individuals who may be at risk of experiencing high perceived fatigability or task failure.

“…Our findings were not in accordance with the evidence from previous research that has shown that usually, men were more fatigable than women when performing isometric contractions at low to moderate intensities [56][57][58][59] and that older subjects were less fatigable than young subjects for upper-and lower-limb muscles for an isometric-contraction fatiguing task at the same relative intensity [52,60]. However, it is well known that these discrepancies are task specific [57,61], rely on the details and demands of the task [17], and are associated with anatomical, biomechanical, and physiological factors [17,42,56,62,63].…”

“…First, the randomization sampling procedure should be carried out with a greater sample to reduce sample bias and clarify some of the results obtained. Second, since TTF is dependent on the will of the participants to maintain (or not) the task, and is related to perceived fatigability [14,42], TTF may be underestimated for some participants. So, in future studies, it would be important to add other performance and perceived fatigability outcomes to check the perceptual influence on performance.…”

“…G*Power 3.1.9.2 software was used to calculate the sample size (G*Power ©; University of Düsseldorf, Düsseldorf, Germany). To analyze the differences before and after performing the task, we used a pre-post study that used the variable of time-to-task failure point (TTF) throughout the upper-limb isometric task, which found a significant correlation in performance fatigability (TTF) (p < 0.01) [42]. Thus, to achieve a statistical confidence of 95%, with a 2-tailed hypothesis test and a large effect size of 0.90, an α-error of 0.05, and a power of analysis of 0.80 (β error = 20%) were chosen.…”

Upper-limb position-sustained tasks (ULPSIT) are involved in several activities of daily living and are associated with high metabolic and ventilatory demand and fatigue. In older people, this can be critical to the performance of daily living activities, even in the absence of a disability. Objectives: To understand the ULPSIT effects on upper-limb (UL) kinetics and performance fatigability in the elderly. Methods: Thirty-one (31) elderly participants (72.61 ± 5.23 years) performed an ULPSIT. The UL average acceleration (AA) and performance fatigability were measured using an inertial measurement unit (IMU) and time-to-task failure (TTF). Results: The findings showed significant changes in AA in the X- and Z-axes (p < 0.05). AA differences in women started earlier in the baseline cutoff in the X-axis, and in men, started earlier between cutoffs in the Z-axis. TTF was positively related to AA in men until 60% TTF. Conclusions: ULPSIT produced changes in AA behavior, indicative of movement of the UL in the sagittal plane. AA behavior is sex related and suggests higher performance fatigability in women. Performance fatigability was positively related to AA only in men, where movement adjustments occurred in an early phase, though with increased activity time.

Purpose: Type 2 diabetes mellitus (T2DM) emphasizes the maintenance of high levels of physical activity and requires interventions tailored to the characteristics of each patient. We hypothesized that T2DM combined with diabetic kidney disease (DKD) could increase skeletal muscle fatigability, becoming a specific contributor to physical inactivity. This study aimed to determine the effects of DKD complications on fatigability and the relationship between fatigability and physical activity in patients with T2DM. Methods: The participants were 50 patients with T2DM aged 40–65 years with an estimated glomerular filtration rate of 30 ml/min/1.73 m2 or higher. An experimental protocol was performed using a isokinetic dynamometer to assess muscle function. Fatigability (maximal voluntary concentric contraction [ΔMVCC] velocity, maximal voluntary isometric contraction [ΔMVIC] torque) was calculated, indicating the decrease in angular velocity and muscle strength associated with the exercise task. The patient characteristics, physical activity (IPAQ-SV), knee extension strength, and skeletal muscle index were evaluated. Participants were divided into two groups (DKD and non-DKD) according to the presence or absence of DKD, and ΔMVCC velocity and ΔMVIC torque were compared. Results: ΔMVCC velocity was significantly higher in the DKD group than that in the non-DKD group (p<0.05). Similarly, ΔMVIC torque was significantly higher in the DKD group compared with the non-DKD group (p<0.05). Subgroup analysis showed that ΔMVCC velocity was independently associated with physical activity in the DKD group (odds ratio: 0.045, 95% confidence interval: 0.913–0.999). Conclusion: Fatigability increased with DKD in patients with T2DM and may be related to physical activity.
