Abstract: C bell, PG, Stewart, IB, Sirotic, AC, and Minett, GM. Title: The effect of overreaching on neuromuscular performance and wellness responses in Australian rules football athletes. J Strength Cond Res 34(6): 1530–1538, 2020—This study seeks to evaluate the effect of periodized fluctuations in training load on wellness and psychological questionnaires, perceived exertion, performance, and neuromuscular measures in team-sport athletes. Thirteen amateur Australian rules football athletes completed 6 weeks of periodized training, consisting of 2-week normal training (NT), intensified training (IT), and taper training (TT). Training sessions were quantified using global positioning system devices, heart-rate, and session rating of perceived exertion (sRPE), with wellness (general soreness, sleep quality/quantity, readiness to train, fatigue, stress, mood, and motivation) questionnaires collected daily. Psychological (Recovery-Stress Questionnaire for Athletes) and physical performance (countermovement jump, cycle ergometer peak power, 30-m sprint, and 2-km time trial) markers were measured after each training period. Perceived (sRPE) and mechanical loading were higher for IT than NT, and IT than TT ( p 0.03 d = 0.65–25.34). Cycle ergometer peak power, 30-m sprint, 2-km time trial, and countermovement jump height showed reductions in performance after IT compared to initial testing ( p 0.02 d = 0.51–1.46), with subsequent increases in performance after TT ( p 0.04 d = 0.66–2.27). Average wellness was higher during NT compared to IT ( p = 0.005 d = 1.11). Readiness to train did not significantly differ from NT to IT or TT ( p 0.55 d = .59) however, readiness to train did improve during TT after the IT ( p = 0.01 d = 1.05). The disturbances in performance, perceptual, and mood states may indicate a state of functional overreaching. The findings suggest that an averaged wellness score may be useful in potentially identifying overreaching. However, despite the popularity of wellness in monitoring systems, these measures overall demonstrated a limited capacity to differentiate between periodized fluctuations in load.

Abstract: Investigations into the specificity of rugby union training practices in preparation for competitive demands have predominantly focused on physical and physiological demands. The evaluation of the contextual variance in perceptual strain or skill requirements between training and matches in rugby union is unclear, yet holistic understanding may assist to optimize training design. This study evaluated the specificity of physical, physiological, perceptual, and skill demands of training sessions compared with competitive match play in preprofessional, elite club rugby union. Global positioning system devices, video capture, heart rate, and session ratings of perceived exertion were used to assess movement patterns, skill completions, physiologic, and perceptual responses, respectively. Data were collected across a season (training sessions n = 29 matches n = 14). Participants (n = 32) were grouped in playing positions as: outside backs, centers, halves, loose forwards, lock forwards, and front row forwards. Greater total distance, low-intensity activity, maximal speed, and meters per minute were apparent in matches compared with training in all positions (P 0.90). Similarly, match heart rate and session ratings of perceived exertion responses were higher than those recorded in training (P 0.8). Key skill completions for forwards (ie, scrums, rucks, and lineouts) and backs (ie, kicks) were greater under match conditions than in training (P 1.50). Considerable disparities exist between the perceptual, physiological, and key skill demands of competitive matches versus training sessions in preprofessional rugby union players. Practitioners should consider the specificity of training tasks for preprofessional rugby players to ensure the best preparation for match demands.

Abstract: Wellness questionnaires are common in monitoring systems, yet the sensitivity to variations in acute training intensity is unclear. This study examined the controlled dosage effects of differing exercise intensities on wellness variables and subsequent associations with neuromuscular performance. Participants (
