“…This indicates that, unlike the ChestL-ChestR subnetwork, slow type-I muscle fibers in the ArmL muscle cannot communicate with intermediate type IIa and fast IIb muscle fibers in the ArmR muscle, leading to a links strength profile with higher initial stratification (spread) during Exercise 1. The uncovered differences between the ChestL-ChestR and ArmL-ArmR subnetworks may reflect the distinct role these subnetworks play in push-up movements — while pectoralis major (Chest) have primary motor role during push-up movements (higher myoelectrical activation), triceps brachii (Arm) has a secondary role 38 , 39 . Interestingly, the modules with strongest links in both same-type muscle subnetworks ChestL-ChestR and ArmL-ArmR are those that correspond to the low-low ([F1-F2]—[F1-F2]) frequency bands interactions, even though subnetworks play different role in push-up movements.…”

Fundamental movement patterns require continuous skeletal muscle coordination, where muscle fibers with different timing of activation synchronize their dynamics across muscles with distinct functions. It is unknown how muscle fibers integrate as a network to generate and fine tune movements. We investigate how distinct muscle fiber types synchronize across arm and chest muscles, and respond to fatigue during maximal push-up exercise. We uncover that a complex inter-muscular network of muscle fiber cross-frequency interactions underlies push-up movements. The network exhibits hierarchical organization (sub-networks/modules) with specific links strength stratification profile, reflecting distinct functions of muscles involved in push-up movements. We find network reorganization with fatigue where network modules follow distinct phase-space trajectories reflecting their functional role and adaptation to fatigue. Consistent with earlier observations for squat movements under same protocol, our findings point to general principles of inter-muscular coordination for fundamental movements, and open a new area of research, Network Physiology of Exercise.

“…After the electrodes were secured, a quality check was performed to ensure EMG signal validity. The aforementioned Chest and Arm muscles were selected since they present the highest myoelectrical activity during the push-up movement 40,41 . Data were recorded using a mDurance system (mDurance Solutions S.L., Granada, Spain), which includes a portable sEMG system (Shimmer3 EMG unit, Realtime Technologies LGd, Dublin, Ireland 42 , and processed by means of Matlab (Mathworks, Natik, MA, USA).…”

Fundamental movement patterns require continuous skeletal muscle coordination, where muscle fibers with different timing of activation synchronize their dynamics across muscles with distinct functions. It is unknown how muscle fibers integrate as a network to generate and fine tune movements. Here we investigate how distinct muscle fiber types dynamically synchronize as a network across muscles and respond to fatigue during consecutive bouts of maximal exercise. We uncover that a complex inter-muscular network of muscle fiber cross-frequency interactions underlies basic movements. The network exhibits hierarchical organization of sub-networks and modules with specific links strength stratification profile, reflecting distinct functions of the muscles involved in movements. We find complex network reorganization with fatigue where network modules follow distinct phase-space trajectories reflecting their functional role and adaptation to fatigue. The findings reveal general principles of inter-muscular coordination for fundamental movements, and open a new area of research, Network Physiology of Exercise.

“…PU is an exercise performed to increase the dynamic stability of the upper extremity. At the initial phase of the PU, the hands are placed on the floor directly under the shoulders and stand with the feet shoulder-width apart (Kowalski et al, 2022). Then the body lowers to the floor by flexing the elbow after the elbow reaches 90° flexion the body is returned to the initial position (Freeman et al, 2006).…”

The push-up is a basic exercise commonly used in strength training. This exercise can be performed on different surfaces. The purpose of this study is to compare the muscle activation of the pectoralis major and triceps brachii muscles during push-up exercises performed on stable and unstable surfaces. Nineteen males participated in this study. Bosu ball and ring apparatus were used as unstable surfaces and the floor was used as a stable surface. Subjects performed 5 repetitions of PU on the different surfaces. A one-way repeated-measures analysis of variance was used to compare the muscle activities between the surfaces. Muscle activation of PM was significantly greater in the ring than on the floor and the Bosu ball (p0.05). In conclusion, using the ring apparatus as an unstable surface increase the PM muscle activation in PU exercise. Muscle activation of TB was not influenced by surface stability in PU.
