  • The effects of menstrual cycle phase on jumping performance in women's football players: a systematic review
    Publication . Marques, Catarina; Rebelo, Miguel; Serrano, João; Fonseca, Helder; Frontiers in Sports and Active Living
    Objectives: This systematic review aimed to evaluate the available evidence on the influence of menstrual cycle (MC) phases on vertical jump performance (countermovement jump and squat jump height) in female football players. Design: The review was conducted in accordance with PRISMA guidelines and registered in PROSPERO (ID1035357). Methods: A systematic search was performed in PubMed, Scopus, and SPORTDiscus (EBSCO). Studies were included if they involved female football players, assessed vertical jump performance, and compared performance across MC phases. Methodological quality was assessed using a modified Downs & Black checklist for non-interventional studies. Results: Seven studies met the inclusion criteria. Substantial heterogeneity was observed regarding MC phase determination procedures, sample characteristics, and testing protocols. Although some studies reported higher vertical jump height values during the follicular or ovulatory phases, no statistically significant differences were found. Conclusions: Current evidence is insufficient to determine whether MC phases influence vertical jump performance in female football players. Findings should be interpreted cautiously due to methodological limitations in MC phase determination and low statistical power. Future research should aim to standardize protocols, use objective hormonal verification, and recruit larger samples.

  • Neuromuscular characteristics of female futsal players: A systematic review
    Publication . Marques, Catarina; Rebelo, Miguel; Serrano, João; Fonseca, Helder; Sports
    Background: This systematic review aimed to analyze and synthesize the available evidence on the neuromuscular profile of female futsal players. Methods: The review was conducted in accordance with PRISMA guidelines and registered with PROSPERO (CRD420251055503). PubMed, Scopus and SPORTDiscus databases were searched until May 2025. The eligibility criteria were defined using the PECOS strategy. The methodological quality of the included studies was evaluated using the Downs and Black modified version. Results: Twenty-three studies were included, covering a total of 433 female players between the ages of 12 and 27. Muscle strength was assessed mainly using an isokinetic dynamometer, jumping ability using the countermovement jump and squat jump, sprinting using the 10 m, 20 m and 30 m tests and agility and change of direction (CoD) using the Illinois agility test. Elite players generally showed a better performance in agility and CoD tests compared to lower-level players. Conclusions: This review provides a comprehensive overview of the neuromuscular profile of female futsal players and highlights trends related to the competitive level. These findings may support evidence-based practices for performance evaluation, training and injury prevention. More studies are needed to standardize methods and understand differences between competitive levels.
