“…SMS increases with physiological muscle fatigue during sustained muscle exertion, especially when using large loads (Saito and Mano 1989;Nagasawa et al 2000). Nagasawa et al (2000) examined relationships between persistence time and SMS in sustained static hand gripping with constant workload, and reported that the peak of SMS was at 53.3 ± 19.7 s (75% MVC) and 95.0 ± 36.3 s (50% MVC).…”

“…In addition, after the force value in any workload reaches a steady state at 15-20% MVC, it decreases very little (Yoshimura et al 1996;Nagasawa et al 2000;Yamaji et al 2000;Yamaji et al 2004). Also, the differences among individuals (Yamaji et al 2002;Yamaji et al 2004) and between genders (Maughan et al 1986;Laforest et al 1990) increase during a large decrease in force, until reaching a steady state.…”

“…It was reported that the persistence time of sustained gripping is very short at levels above 75% MVC, with little difference among individuals (West et al 1995;Nagasawa et al 2000), while the load that could be maintained under sustained gripping without a force decrease is 15% MVC (Yamaji et al 2002). Therefore, the maximum and minimum increase .…”

“…However, because measurement of muscle endurance using a progressive workload is without precedent, the effect of decreasing force is not entirely clear. Meanwhile, SMS increases with physiological muscle fatigue when exerting sustained forces with large loads (Saito and Mano 1989;Nagasawa et al 2000), with several reports on the relationship between these two (Kilbom et al 1983;West et al 1995;Nagasawa et al 2000). It is possible that a relationship between the exerted force and the corresponding muscle fatigue sensation in the loads were considered to be 70-80% MVC and 10-20% MVC in the progressive workload.…”

Muscle endurance is one of the important composite factors to health-related physical fitness. However, previous measurement techniques for evaluation of isometric muscle endurance have been problematic, including rapid increase of blood pressure and heart rate. The progressive workload method which gradually increases the load can reduce subject's physical and mental burden and is safe even for the elderly. This study aims to examine the relationship between exerted force and subjective muscle-fatigue sensation (SMS) of the antebrachial region as well as differences with respect to gender during sustained static gripping. Subjects consisted of 12 males (age 20.8 ± 1.6 years) and 15 females (age 20.5 ± 1.3 years) with no history of neuromuscular disorders. They performed sustained static gripping, in which the demand values are gradually increased: 10 sec for 20% maximal voluntary contraction (MVC), 20 sec each for 30, 40, 50, 60, and 70% MVC, and 10 sec for 80% MVC. Demand values (each %MVC) were determined based on each subject's MVC. The forces exerted during at the demand values of 70-80% MVC were significantly lower in males than in females. A gender difference in SMS between male and female subjects occurred at demand values of 40-60% MVC. In short, even when maintaining the same exertion force during demand values of 40-60% MVC, males may experience greater physical fatigue than females. subjective musclefatigue sensation; gender difference; progressive workload.

This study aimed to examine relationships between force outputs during sustained isometric grips (SIG) and intermittent repeated grips (IRG) with three relative target forces (50%, 75%, and 100% MVC), and subjective muscle-fatigue sensation (SMS) and blood lactate (La) during and after gripping tests. Ten young males performed sustained grip tests with 2 grip types and 3 target forces for 6 min. La and maximal grip strength were measured before, just after and 4 min and 7 min after each grip test. SMS of the forearm was measured every 30 s during and after each grip test. The relationships of average grip force in every 30 s between SIG and IRG were not good. The La value after IRG tests with 75% and 100% MVCs tended to be higher than that in the other conditions. The tendency for decline differs with grip type, intensity (target forces) and the force outputs among the conditions. The muscle fatigue level in the SIG and IRG may differ largely even when using the same target force. Although the SIG imposes a larger burden on subjects than the IRG, La after gripping work is lower.
