Topics in Exercise Science and Kinesiology Volume 5: Issue 1, Article 3, 2024. The rugby codes (i.e., rugby union, rugby league, rugby sevens [termed ‘rugby’]) are team-sports that impose complex physical demands upon players which in-turn, leads to domain-specific fatigue (e.g., neuromuscular, cardio-autonomic). Quantifying post-match fatigue through various methods and metrics is important to monitor player fatigue status, which influences training readiness. The specific and general barriers limiting the use of post-match fatigue monitoring in rugby are not presently known. Therefore, the aims of this study were to identify specific and general barriers (clusters of specific barriers) to the use …

Identifying ideal ranges of training load (TL) and recovery status before soccer games is essential to maximize game-day performance. PURPOSE: To determine how accumulative TL and subjective fatigue affect performance during the game. METHODS: Twenty-one male semi-professional soccer players (mean ± standard deviation; age: 22 ± 2 years; mass: 77.3 ± 6.9 kg) wore a player tracking device to monitor TL during each practice and game. A 7-day accumulation of high speed running and sprinting (HSR+Sprint, ³12.30 mph), total distance (TD), low acceleration (LowACC: 0.50-1.99 m×s-2), and high acceleration (HighACC: 2.00-50.00 m×s …

Alternating Muscle Activation Patterns Across The Deltoid Muscles During Sustained Fatiguing Contractions, Ningzhen Zhao, Xin Yu, Lisa Griffin

Alternating muscle activation (AMA) across synergists has been identified in lower-extremity muscles that may function to prolong force output during sustained contractions; however, this has not yet been identified in upper extremity muscles. AMA consists of two periods: co-activation (Co-A), in which a pair of synergists are simultaneously increasing or decreasing EMG amplitude, and trade-off (TO), in which the EMG amplitude of one muscle is increasing while the EMG amplitude of a synergist is decreasing. We hypothesized that TO duration would increase and Co-A duration would decrease during fatigue. PURPOSE: To investigate AMA patterns during sustained submaximal isometric fatiguing …

Purpose: Persistent inward calcium and sodium currents (PICs) are crucial for initiation and maintenance of motoneuron firing, and thus muscular force. However, there is a lack of data describing the effects of fatiguing exercise on PIC activity in humans. We simultaneously applied tendon vibration and neuromuscular electrical stimulation (VibStim) before and after fatiguing exercise. VibStim induces self-sustained muscle activity that is proposed to result from PIC activation. Methods: Twelve men performed 5-s maximal isometric plantar flexor contractions (MVC) with 5-s rests until joint torque was reduced to 70%MVC. VibStim trials consisted of five 2-s trains of neuromuscular electrical stimulation (20 …
