Abstract:
[Purpose] This study developed a push-up plus guide and resistance device and investigated the effectiveness of the device. [Subject and Methods] A 39-year-old man presented with moderate pain with left scapular dyskinesis. A newly designed assistance device was used as a push-up plus guide and resistance device (PPGRD). The subject performed the push-up plus exercise without and then with the PPGRD for 2 weeks each. [Results] After performing the push-up plus exercise with the PPGRD for 2 weeks, the serratus anterior muscle power was increased, the pain score was decreased, and the absence of scapular dyskinesis was confirmed. [Conclusion] The PPGRD provided appropriate guidance and prevented excessive trunk flexion during the push-up plus exercise.

Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Mechanism of Breathing III: The Accessory Muscles
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...
