“…In the case of muscle endurance measurements using a constant workload with large loads, the exertion force is strongly affected by muscle blood volume obstruction with an increase in intramuscular pressure (Bonde-Peterson et al, 1975;Clarke et al, 1992;Kahn et al, 1998). Also, blood pressure and heart rate, or pain sensation in the muscles increases (Petrofsky and Hendershot, 1984).…”

This study aimed to examine the relationships between force and subjective muscle-fatigue sensation (SMS), and muscle oxygenation kinetics during sustained static gripping using a progressive workload. Subjects consisted of 10 males (height 173.2Ϯ7.1 cm, body weight 70.3Ϯ15.1 kg, and age 21.1Ϯ1.5 years). They performed sustained static gripping with 7 gradually increasing relative demand values of 20% to 80% maximal voluntary contraction (MVC). The staging of the progressive workload was 10 s for 20% MVC, 20 s each for 30, 40, 50, 60, and 70% MVC, and 10 s for 80% MVC. Borg's SMS was used to measure the fatigue sensation of the antebrachial region in a pre-test and every 10 s during the test. The time to reach minimum Oxy-Hb/Mb appeared at about 50 s (52.6Ϯ25.2 s) after the onset of sustained static gripping, and the time to reach maximum Deoxy-Hb/Mb occurred later at 90 s. Significant and high correlations (rϭ0.632-0.721) were found between the time to reach maximum Deoxy-Hb/Mb, and Peak Force Time and Average Force. Even though the demand values caused a workload increase and reached 50% MVC, the change of Total Hb/Mb and Oxy-Hb/Mb kinetics was relatively small. Therefore, the effect caused by an obstruction of blood volume may not occur during the progressive workload. It was determined that the contraction time after the peak of SMS is relatively short and an individual difference in force value expands in the phase where SMS reaches its peak.

“…In addition, the muscles develop tension during muscle contractions and thereby the elevated intramuscular pressure compresses the capillaries between the fibers (Sjø gaard, et al, 1986, Sejersted, et al, 1984 ( Figure 1B). This causes blood flow restriction or occlusion to the contracting muscles on the arterial side and expels blood from the muscle on the venous side (muscle pump) (Barnes 1986, Bonde-Petersen, et al, 1975, Gaskell 1877, Kagaya and Ogita 1992, Lind and McNicol 1967, Sadamoto, et al, 1983, Sjø gaard, et al, 1986. Accordingly, changes in vessel geometry due to muscle lengthening/shortening and vessel compression due to developed muscle tension are two major factors which mechanically modify muscle circulation.…”

Muscle contraction mechanically changes vessel geometry and consequently muscle circulation. Lengthening of muscle fiber straightens capillary tortuosity and further increase in muscle fiber length reduces blood flow by extending the capillary while reducing its diameter. The direction of capillary to the fiber long axis will modify the extent of capillary lumen diameter change due to lengthening muscle fiber. During passive stretching in human subjects, the relationship between changes in blood volume (determined by near-infrared spectroscopy: NIRS) and fascicle length differed among the three heads of triceps surae muscles with different fascicle length and pennation angle. Muscle thickness, muscle curvature, and muscle fascicle angle are potential determinants of intramuscular pressure during muscle contraction. Muscle circulation is impeded more in short bulging muscles with great curvature of fibers than in long slender muscles with less curvature. The different response of circulatory parameters across the synergist muscles in the calf and heterogeneity of muscle circulation in the same muscle were observed, partly due to the difference in the pennation angle of the muscle fascicle. The muscle architecture will influence venous outflow by changing the muscle pumping action. This is possibly an indirect way of modifying vasodilation due to difference in muscle architecture.

“…In SIG using high target forces, blood supply into active muscles is checked by rising intramuscular pressure. The intensity level induced the ischemic condition, although it differs by the region of muscle used, was reported as 50-75% MVC [22,23]. We hypothesized that IRG with a blood supply during relaxation period promotes aerobic metabolism, in other words, it facilitates lactic acid rejection in ATP reconstruction.…”

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.
