This study aimed to analyze the time under tension (TUT) behavior in the bench press exercise performance in recreationally trained individuals. A systematic review was performed based on the PRISMA recommendations and registered on PROSPERO (CRD42022301830). MEDLINE (PubMed), Scopus, SPORTDiscus, and Lilacs (BVS) databases were consulted with the terms (resistance training [Title/Abstract]) OR (strength training [Title/Abstract]) AND (time under tension [Title/Abstract]). Cohort studies that analyzed the TUT in the bench press exercise in individuals with experience in resistance training were included. We used the Critical Appraisal Skills Program tool to analyze the methodological quality of the included studies. Thirteen studies met the inclusion criteria. The total number of participants was 215 individuals (179 men and 36 women). TUT was analyzed from the manipulation of each study variable. The behavior of the TUT in the bench press exercise varies according to the training protocol and method used. The TUT and the number of repetitions can vary to quantify the training volume.

Considering the great popularity of eccentric-based training, the purpose of this review is to first provide the scientific rationale for its use; second, summarize the eccentric-based training modalities that can be used; and finally, offer practical recommendations on how to implement eccentricbased modalities to enhance sports performance. The molecular and neural mechanisms underlying eccentric actions are partially distinct from those of concentric and isometric actions. During eccentric actions, theories suggest a strain-induced modulation of actin-myosin interactions at the crossbridge level, activation of structural protein titin, and winding of titin on actin. Eccentric acute physiological responses differ from concentric exercise responses, including variations in neuromuscular, metabolic, hormonal, and anabolic signaling. Eccentric training elicits greater improvements in muscle strength, power, and stretch-shortening cycle function compared with concentric-only or traditional resistance training. Therefore, eccentric-based training can lead to unique neuromuscular (e.g., improved coordination of motor units) and morphological (e.g., increased muscle fascicle length and enhanced distal cross-sectional area) adaptations that could play a key role in sport performance. Practitioners may implement eccentric exercises with external loads, fully eccentric-based exercises (e.g., Nordic hamstring curl), accentuated eccentric loading, flywheel resistance exercise, and plyometrics to develop specific physical adaptations in line with their goals. Eccentric work (e.g., for hamstrings) can be obtained during other exercises such as downhill running tasks, decelerations, and sprinting activities. Practitioners need to be aware that no single “silver bullet” training modality exists; consequently, practitioners should use a combination of eccentric-based training approaches with their athletes to obtain the desired adaptations.

Key performance indicators (KPIs) are commonplace in business and sport. They offer an objective means to link data and processes with performance outcomes. Yet, their application in sports performance, particularly team sports, is not without issue. Here, we review 4 key issues relating to KPI application in team sports; lack of a universal definition, complexity of performance, drifting from on-field performance goals with off-field targets, and agency issues across different key stakeholders. With these issues relating to sports performance KPIs in mind, we propose a complementary approach to help practitioners focus on implementing the conditions that create performance environments and opportunities for success in a complex sporting environment. Ongoing process trackers (OPTs) are quantifiable measures of the execution of behaviors and processes that create the environments, cultures, and conditions for successful performance outcomes. This approach equips sports science practitioners with key questions they can ask themselves and their team when starting to select and use OPTs in their program.

Sprinting is a key component for many individual and team sports. Therefore, to enhance sprint performance, various training methods are widely used by coaches and practitioners, including maximum sprint speed and resisted sprint training. Resisted sprinting with sled towing is a method that has recently received considerable attention from the sport science community. However, to date, no consensus exists regarding its acute and chronic effects in team sport athletes. This narrative review aimed to (a) review and analyze the mechanics of sprinting under unresisted and resisted conditions with a specific focus on team sport disciplines; (b) provide a thorough and applied discussion on the importance of considering acute and chronic effects of sled loading on technique, electromyographic activity, and force production, as well as on the role of muscle architecture and neural factors in sled training; (c) analyze the effects of increasing sled loads during acceleration and maximum velocity phases on contact and flight phases, while concomitantly examining kinetic, kinematic, and neuromuscular aspects, because all these factors affect each other and cannot be properly understood in isolation.

Altering set configurations during a resistance training program can provide a novel training variation that can be used to modify the external and internal training loads that induce specific training outcomes. To design training programs that better target the defined goal(s) of a specific training phase, strength and conditioning professionals need to better understand how different set configurations affect the training adaptations that result from resistance training. Traditional and cluster set structures are commonly implemented by strength and conditioning professionals as part of an athlete’s resistance training program. The purpose of this review is to offer examples of the practical implementation of traditional and cluster sets that can be integrated into a periodized resistance training program.
