“…Thus, the category ratio (CR10) was administered to assess the limb discomfort, and the participant was required to perform a new MVC test. The menstrual cycle of women was not monitored in the present study, because there is strong evidence to suggest that this variable does not influence isometric strength (Nicolay, Kenney, & Lucki, ) regardless of the use of contraceptive medication (Elliott, Cable, & Reilly, ).…”

The brain mechanisms by which music‐related interventions ameliorate fatigue‐related symptoms during the execution of fatiguing motor tasks are hitherto under‐researched. The objective of the present study was to investigate the effects of music on brain electrical activity and psychophysiological measures during the execution of an isometric fatiguing ankle‐dorsiflexion task performed until the point of volitional exhaustion. Nineteen healthy participants performed two fatigue tests at 40% of maximal voluntary contraction while listening to music or in silence. Electrical activity in the brain was assessed by use of a 64‐channel EEG. The results indicated that music downregulated theta waves in the frontal, central, and parietal regions of the brain during exercise. Music also induced a partial attentional switching from associative thoughts to task‐unrelated factors (dissociative thoughts) during exercise, which led to improvements in task performance. Moreover, participants experienced a more positive affective state while performing the isometric task under the influence of music.

“…For the lower extremity muscles, the menstrual cycle phase did not influence the fatigue index ( Dibrezzo et al, 1988 ; Janse de Jonge et al, 2001 ; Friden et al, 2003 ; Ansdell et al, 2019 ). However, for the upper extremity muscles, some indicated a ∼4% greater decline in force (i.e., greater exercise-induced fatigability) during the follicular phase compared to the luteal phase (52 ± 4 vs. 56 ± 4% of baseline, respectively) ( Pallavi et al, 2017 ), whereas others reported a ∼15% larger reduction in force during the luteal phase (follicular: 96 ± 19 vs. luteal: 81 ± 11% baseline) ( Nicolay et al, 2008 ; Table 2 ). Differences in the task performed may also have contributed to the mixed results.…”

“…For the upper extremity muscles, the results are also mixed as some reported 5–20% greater strength during the follicular (i.e., low levels of estrogen and progesterone) ( Bassey et al, 1995 ; Boot et al, 1999 ; Pallavi et al, 2017 ), and 10% greater strength during the ovulatory or luteal phases (i.e., greater estrogen concentration compared to the follicular phase) ( Phillips et al, 1996 ; Sarwar et al, 1996 ). Others showed no changes across the cycle ( Janse de Jonge et al, 2001 ; Friden et al, 2003 ; Nicolay et al, 2008 ; Jarvis et al, 2011 ; Sakamaki-Sunaga et al, 2016 ; Table 3 ).…”

Menstrual Cycle Effects on Exercise-Induced Fatigability

Estrogen and progesterone have distinct concentrations across the menstrual cycle, each one promoting several physiological alterations other than preparing the uterus for pregnancy. Whether these physiological alterations can influence motor output during a fatiguing contraction is the goal of this review, with an emphasis on the obtained effect sizes. Studies on this topic frequently attempt to report if there is a statistically significant difference in fatigability between the follicular and luteal phases of the menstrual cycle. Although the significant difference (the P -value) can inform the probability of the event, it does not indicate the magnitude of it. We also investigated whether the type of task performed (e.g., isometric vs. dynamic) can further influence the magnitude by which exercise-induced fatigue changes with fluctuations in the concentration of ovarian hormones. We retrieved experimental studies in eumenorrheic women published between 1975 and 2019. The initial search yielded 921 studies, and after manual refinement, 46 experimental studies that reported metrics of motor output in both the follicular and luteal phases of the menstrual cycle were included. From these retrieved studies, 15 showed a statistical difference between the luteal and follicular phases (seven showing less fatigability during the luteal phase and eight during the follicular phase). The effect size was not consistent across studies and with a large range (-6.77; 1.61, favoring the luteal and follicular phase, respectively). The inconsistencies across studies may be a consequence of the differences in the limb used during the fatiguing contraction (upper vs. lower extremity), the type of contraction (isometric vs. dynamic), the muscle mass engaged (single limb vs. full body), and the techniques used to define the menstrual cycle phase (e.g., serum concentration vs. reported day of menses). Further studies are required to determine the effects of a regular menstrual cycle phase on the exercise-induced fatigability.

Hand is made up of bones, tendons, ligaments, nerves and blood vessels that can be easily debilitated and injured if the hand tool is not design ergonomically. Recently researchers have examined the effects of individual, environmental and occupational factors on hand grip strength. However, information on the influence of hand tool design on hand grip strength is still lacking. The aim of this paper is to provide a comprehensive review of factors influencing hand grip strength focusing more towards hand tool design factors. The authors searched the journal articles, book and guidelines from the online databases of Google Scholar, ScienceDirect and Pubmed. Fourteen factors includes handle diameter, handle length, handle orientation, handle shape, handle material, handle flange, handle inter distance/grip span, grip method, tool weight, tool center of gravity, tool sharpness, trigger type and size, spring stiffness as well as vibration exposure were found to have significant effect on the hand grip strength. This review identified that the handle diameter is the most significant factor for hand grip strength.
