AbstractIn cooperative breeding systems, inclusive fitness theory predicts that nonbreeding helpers more closely related to the breeders should be more willing to provide costly alloparental care and thus have more impact on breeder fitness. In the red-cockaded woodpecker (), most helpers are the breeders' earlier offspring, but helpers do vary within groups in both relatedness to the breeders (some even being unrelated) and sex, and it can be difficult to parse their separate impacts on breeder fitness. Moreover, most support for inclusive fitness theory has been positive associations between relatedness and behavior rather than actual fitness consequences. We used functional linear models to evaluate the per capita effects of helpers of different relatedness on eight breeder fitness components measured for up to 41 years at three sites. In support of inclusive fitness theory, helpers more related to the breeding pair made greater contributions to six fitness components. However, male helpers made equal contributions to increasing prefledging survival regardless of relatedness. These findings suggest that both inclusive fitness benefits and other direct benefits may underlie helping behaviors in the red-cockaded woodpecker. Our results also demonstrate the application of an underused statistical approach to disentangle a complex ecological phenomenon.

Purpose: To systematically review the evidence investigating the implementation of cardiorespiratory (CR) training in adults following a stroke and to understand how interventions are prescribed to address cardiorespiratory fitness (CRF).
Methods: Medline, CINAHL, EMBASE, EMCARE, Scopus, PEDro and ProQuest were searched from inception until January 2024. Inclusion criteria were studies that included adults following a stroke, investigated CR training interventions and used standardised CRF assessments.

Background: Malnutrition has extensive consequences, affecting multiple levels of functioning, including motor skill impairments. However, current interventions have mainly focused on dietary treatment, often neglecting motor impairments and relying solely on clinical and anthropometric indicators to assess treatment response. This study aims to bridge this gap by examining the combined effect of ready-to-use supplementary food (RUSF) and high-intensity motor learning (HiML) on motor skill-related physical fitness in children with moderate thinness (MT).

Background: Breast cancer treatments often cause serious side effects, but physical exercise has shown the potential to improve both the physical and psychological health outcomes of survivors. This review and meta-analysis aimed to synthesize and analyze the scientific evidence on the effectiveness of concurrent training on physical, psychological, and biomarkers variables on breast cancer survivors.; Methods: A systematic review and meta-analysis was registered in PROSPERO (CRD42024571851).

Introduction: This systematic review is aimed to evaluate the outcomes of published studies on the topic of fatigue-induced neuromuscular and biomechanical changes after anterior cruciate ligament (ACL) reconstruction.
Evidence Acquisition: The identification of studies involved a search across three databases - PubMed, Scopus, and Sportdiscus - until July 2023. The key terms utilized were fatigue, anterior cruciate ligament, biomechanics, electromyography, and landing.
