Dose –Response Modelling of Resistance Exercise Across Outcome Domains in Strength and Conditioning: A Meta-analysis
ConclusionsThe current meta-analysis represents the most comprehensive investigation of dose –response relationships across a range of outcome domains commonly targeted within strength and conditioning to date. Results demonstrate the magnitude of improvements is predominantly influenced by training intensity of load and the outcome measured. When considering the effects of intensity as a % 1RM, profiles differ across outcome domains with maximum strength likely to be maximised with the heaviest loads, vertical jump performance likely to be maximised with relatively light loads (~ 30% 1RM), and power likely to be maxim...

Supervised Versus Unsupervised Exercise for the Improvement of Physical Function and Well-Being Outcomes in Older Adults: A Systematic Review and Meta-analysis of Randomized Controlled Trials
ConclusionsCurrent evidence suggests that both SUP and UNSUP programs are safe and could exert benefits on physical function and HRQoL. However, despite being associated with similar attendance rates, SUP might offer some additional benefits, although further high-quality research (i.e., accounting for confounding factors such as presence of supervised sessions in UNSUP or vice versa, as well as equating the exercise dose) is necessary to confirm these findings.PROSPERO Registration NumberCRD42022326420.

A Longitudinal Mixed Methods Case Study Investigation of the Academic, Athletic, Psychosocial and Psychological Impacts of Being of a Sport School Student Athlete
ConclusionsThis mixed method, longitudinal study demonstrated sport school involvement resulted in many positive academic (e.g. good grades), athletic (e.g. fitness development), psychosocial (e.g. enhanced confidence) and psychological (e.g. improved resilience) impacts attributed to the academic and athletic support services provided. However, juggling heavy academic and athletic workloads posed challenges leading to negative impacts including fatigue, pressure, stress and injury. Furthermore, holistic impacts may be sex dependent and further support may be required for female student athletes in sport school environment...

The Effect of Strength Training Methods on Middle-Distance and Long-Distance Runners ’ Athletic Performance: A Systematic Review with Meta-analysis
ConclusionsStrength training with high loads can improve performance (i.e., time trial, time to exhaustion) in middle-distance and long-distance runners. A greater improvement may be obtained when two or more strength training methods (i.e., high load training, submaximal load training and/or plyometric training) are combined, although with trivial effects onVO2max, vVO2max, MMSS, or sprint capacity.

Injury in Starting and Replacement Players from Five Professional Men ’s Rugby Unions
ConclusionThis study demonstrated a lower injury incidence in replacement players compared with starters in the second half of matches, with a higher injury burden for replacement players due to higher mean injury severity. (Source: Sports Medicine)

Physical Activity and Cognitive Performance in Early Childhood: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
ConclusionsAlthough further research is warranted, our findings suggest that PA interventions may improve cognitive performance in early childhood, particularly in the domains of attention, inhibition, working memory, cognitive flexibility and vocabulary. These findings might support the implementation of PA interventions from early childhood.PROSPERO RegistrationCRD42021249319. (Source: Sports Medicine)

DNA Methylation in the Adaptive Response to Exercise
AbstractEmerging evidence published over the past decade has highlighted the role of DNA methylation in skeletal muscle function and health, including as an epigenetic transducer of the adaptive response to exercise. In this review, we aim to synthesize the latest findings in this field to highlight: (1) the shifting understanding of the genomic localization of altered DNA methylation in response to acute and chronic aerobic and resistance exercise in skeletal muscle (e.g., promoter, gene bodies, enhancers, intergenic regions, un-annotated regions, and genome-wide methylation); (2) how these global/regional methylation cha...

Glycaemic Effects of a 156-km Ultra-trail Race in Athletes: An Observational Field Study
ConclusionUltra-endurance athletes were exposed to hyperglycaemia during the 48-h post-race period, possibly linked to muscle damage and inflammation. Strategies to mitigate muscle damage or subsequent inflammation before or after ultra-trail races could limit recovery hyperglycaemia and hence its related adverse health consequences.Trial Registration NumberNCT05538442 2022 –09-21 retrospectively registered.Graphical abstract (Source: Sports Medicine)

Time to Reflect on Return to Sport Timing Following ACL Reconstruction
AbstractThe time of return to sport following anterior cruciate ligament (ACL) reconstruction is a commonly discussed topic within clinical settings and the sports medicine literature. Emerging science has demonstrated protective effects of delaying the time of sport clearance on athlete reinjury. Though a single time cutoff is unlikely to be applicable for all athletes, large inconsistencies in the time of return to sport clearance are present in both the literature and within prescribed clinical protocols. A multitude of patient factors, such as perceived function, objective function, confidence, post-operative goals,...

Differences in Injury Profiles Between Female and Male Athletes Across the Participant Classification Framework: A Systematic Review and Meta-Analysis
ConclusionsFemale sex was a key determinant of sports-related injuries beyond ACL injury including foot/ankle injury, bone stress injury and sports-related concussion. Male sex was a key determinant of hip/groin, hamstring injury and upper limb injury.Trial RegistryPROSPERO registration number: CRD42017058806 (last updated on 7th June 2023).

Exercise-Regulated Mitochondrial and Nuclear Signalling Networks in Skeletal Muscle
AbstractExercise perturbs energy homeostasis in skeletal muscle and engages integrated cellular signalling networks to help meet the contraction-induced increases in skeletal muscle energy and oxygen demand. Investigating exercise-associated perturbations in skeletal muscle signalling networks has uncovered novel mechanisms by which exercise stimulates skeletal muscle mitochondrial biogenesis and promotes whole-body health and fitness. While acute exercise regulates a complex network of protein post-translational modifications (e.g. phosphorylation) in skeletal muscle, previous investigations of exercise signalling in huma...

Resistance Exercise Minimal Dose Strategies for Increasing Muscle Strength in the General Population: an Overview
AbstractMany individuals do not participate in resistance exercise, with perceived lack of time being a key barrier. Minimal dose strategies, which generally reduce weekly exercise volumes to less than recommended guidelines, might improve muscle strength with minimal time investment. However, minimal dose strategies and their effects on muscle strength are still unclear. Here our aims are to define and characterize minimal dose resistance exercise strategies and summarize their effects on muscle strength in individuals who are not currently engaged in resistance exercise. The minimal dose strategies overviewed were: “...
