“…The exercise has been performed running on a continuous treadmill, so the two muscles work together. 9 The slope has remained constant, which has not caused a special overload on the gastrocnemius muscles as it occurs in the ramp race. 23 The results of this work can be used to understand better the participation of each muscle group in running mechanics and in the appearance of fatigue.…”

“…7 Usually a single device is used to study muscle oxygenation although there are studies that have analysed both muscles to see the influence of stretching on resistance. 9 Both quadriceps and gastrocnemius have a direct action in walking and in running, 10 so the results obtained will depend on their energy production capacity during the tests and the protocol used. 11 The new NIRS devices are associated with display screens (computer, tablet or watch), which allow the measurement in real time the level of SmO 2 that the body uses during physical exercise, outdoor and in laboratory tests.…”

Introduction: Near infrared spectroscopy (NIRS) is a non-invasive technique that is used in the assessment of tissue oxygenation and the monitoring of physical activity. Objective: To determine the influence of sexual, anthropometric and ergospirometric factors on muscle oxygenation of the quadriceps and gastrocnemius, obtained by NIRS during a stress test. Methods: Twenty healthy subjects participated in this study (10 women). Two Humon Hex® devices were placed on the dominant side of the quadriceps and gastrocnemius muscles to measure muscle oxygen saturation (SmO2). The stress test was performed on a treadmill with electrocardiographic control and measurement of oxygen consumption. SmO2 was obtained at rest and after maximum effort during the stress test. In addition, the height, weight, skinfold and waist contour were measured. Bioimpedance was used to obtain the percentages of fat mass and muscle mass, which were used to calculate the relative fat mass (RFM). Results: The SmO2 of both muscles at rest is higher in males than in females. At maximum effort, the SmO2 of the quadriceps is similar in both groups. The SmO2 of both muscles is positively related to height, body mass, percentage of mass muscle and waist contour, and negatively with percentage of mass fat, RFM and skinfold thickness. The negative correlation between fat percentage and oxygen saturation is more evident in females. It was observed that the variables that quantify maximum effort are not related to the SmO2 values, except for the correlation between HR max and SmO2 of the gastrocnemius muscle in males. Conclusion: The SmO2 of recreational athletes is influenced by the location of the device and the fat mass of the subjects. The biggest differences between the sexes are in the gastrocnemius muscle.

“…Assessment of muscle endurance using involuntary twitch contractions involves measuring changes in muscle acceleration of the twitch contractions over a given time. This approach has been used to characterize muscle endurance in various human muscles [11][12][13]. The present study evaluated specific muscle endurance using twitch contractions and accelerometry in two muscles located in the neck; the SCM and the trap muscles, and compared them to the vastus lateralis (VL) muscle in the leg.…”

Endurance of the muscles of the neck are rarely studied. This study measured the endurance index (EI) of the sternocleidomastoid (SCM) and upper trapezius muscles of the neck (trap). The vastus lateralis (VL) was used for comparison. Skeletal muscle endurance of twelve healthy subjects, age 19–22 years, were tested on their SCM and trap in random order on one day, VL was tested on a separate day. Participants were tested in the supine position for the SCM and VL muscles and the prone position for the trap. Muscle contractions consisted of a 5 Hz twitch electrical stimulation for 5 min. Muscle acceleration (resultant vector) was measured using a triaxial accelerometer. EI was the ending acceleration as a percentage of the maximal acceleration. The endurance index (EI) for the SCM, trap, and VL was 42.3 ± 13.0%, 42.3 ± 20.2%, and 92.9 ± 11.0%, respectively. The EI of the VL was significantly higher than the EI of the SCM (t(2,22) = 10.33, p < 0.001) and the trap (t(2,22) = 7.625, p < 0.001). The EI was not different between the SCM and the trap muscle (t(2,22) = 0.004, p = 0.997). In conclusion, the neck muscles had much less endurance than the muscles in the leg and could make fatigued athletes more susceptible to concussions caused by head impacts.
