Background
In archery training, side bridges are performed in a posture similar to archery shooting for training the muscles around the shoulder joint and the shoulder girdle of the pusher.
Aim
The purpose of this study was to determine whether a low-tremor side-bridge exercise for 4 weeks improves bow tremor during archery movements.
Methods
Participants were 20 male college students. First, we measured the tremor during side bridges performed with trunk inclinations of 25°, 40°, 55°, and 70° using an accelerometer attached to the elbow joint and identified low-tremor side bridges. The participants were then randomly divided into intervention and non-intervention groups, and the low-tremor side bridges were performed for 4 weeks.
Results
The effect of the intervention was determined by measuring the total tremor value using an accelerometer attached to the bow and changes in the median power frequency (MdPF) of the middle deltoid, upper trapezius, and lower trapezius. This intervention reduced the bow tremor and the median power frequency of the middle deltoid (p < 0.05).
Conclusions
The findings suggested that the tremor during the archery sighting phase could be reduced by performing side bridges with a specific trunk angle for a certain period of time. This intervention was also shown to reduce the intermediate frequency of the middle deltoid. The reduced tremor can shorten the sighting phase, which can facilitate injury prevention. -

Since the rectus femoris muscle is associated with trauma and disorders such as muscle strain, it is often a target for evaluation and treatment. However, in many studies, measurement results were obtained from only a part of the rectus femoris muscle and used as a representative value without considering the differences across the muscle. The rectus femoris muscle may change shape with knee flexion because the structure is complicated; it has an intramuscular tendon. The purpose of this study was to assess the changes in shape of the rectus femoris muscle during flexion of the knee joint in different directions. Twelve lower limbs of 12 male university students were analyzed. The rectus femoris muscle was divided into eight parts, and short-axis images were taken with an ultrasonic diagnostic imaging device at the knee joint; in extension; flexion at 30 °, 60 °, 90 °, and 120 °; muscle thickness; muscle width; and cross-sectional area. It was suggested that the thickness of the rectus femoris muscle increased from “A" to “F" due to knee flexion, and that this increase occurred because of stretching at the same site. In “G," there was no difference between the angle conditions; conversely, in “H," the muscle thickness decreased due to knee flexion. It should also be noted that D and E have the greatest muscle thickness when measuring in the knee flexion position.

[Purpose] The relationship between the function of the medial vertical arch of the foot and the continuous hopping jump (SLCH) was examined. By confirming the degree of correlation between the jump height and the coefficient of variation(CV), the effect of the medial foot arch on the jump performance was examined. [Results] A significant inverse correlation was found between the jump height CV and the arch height rate difference (r = -0.64, p = 0.013). [Conclusion] It is suggested that the result of the elastic energy of the sole tendon membrane acting as a “spring“ in the vertical movement of the medial longitudinal arch of the foot due to the load affected the coefficient of variation of the jump height and contributed to the stability of the jump.

[Purpose]To examine whether higher-order brain function evaluation can be used to objectively predict outcomes with high accuracy, and verify its validity for determining whether or not to recommend resuming driving to brain injury patients. [Subjects] Eighty-six brain injury patients who hoped to resume driving were recruited. [Method] collected age, Kohs,TMT,and CAT values, as well as determined whether or not to recommend resuming driving. A multi-layer perceptron was constructed on a computer, and the collected data was learned. Thereafter, the classification accuracy was confirmed. [Results] It was possible to determine whether or not to recommend resuming driving to brain injury patients with a probability of 88.24%. [Conclusion] It was not considered appropriate to classify whether or not to resume driving based on higher brain function evaluation alone, as the accuracy of this classification was only 11.76%.
