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.

The aim of this article was to systematically review and provide practical recommendations, where possible, for recovery strategies that are currently in use in soccer-specific practices among adult male professional players. A systematic search was conducted according to PRISMA guidelines on Web of Science, SPORTdiscus, Scopus, and PubMed databases. The effects of cold-based recovery techniques on performance recovery and attenuating the muscle soreness were evident. Complementarily, some evidence was found that favors foam rolling and massage and compression garments. The active recovery and electronic recovery instruments presented little evidence supporting their usefulness in accelerating the recovery process of soccer players.

The implementation of long-term athletic development (LTAD) aims to improve health, physical activity, and performance of all youth. Contemporary LTAD models suggest that a broad range of physical and psychosocial competencies should be developed in youth, but few resources are available for coaches that describe “how” to achieve these outcomes. This article overviews a coaching session framework built around the following components: raise, activate, mobilize, prepare, activity, games, evaluate (RAMPAGE). The framework provides practitioners with information on what can be planned and delivered and when within a coaching session, across multiple ages and stages of development within multiple contexts (e.g., physical education and talent development).
