Abstract:
Background and Aim of the Study: The continuous evolution of sports and athletics necessitates innovative training strategies to optimize athletes’ performance and physical fitness. High-Intensity Circuit Training (HICT) has emerged as a time-efficient method that combines high-intensity exercises with minimal rest, targeting various muscle groups to enhance physical fitness components. Therefore, this systematic review aims to evaluate the effectiveness of HICT on physical fitness components among athletes to provide a clear, evidence-based understanding of HICT’s benefits and limitations.
Material and Methods: A comprehensive search strategy was employed, retrieving articles published before September 24, 2023, from databases including the Cochrane Central Register of Controlled Trials, PubMed, and Google Scholar. The selection process followed the PRISMA guidelines, focusing on studies that assessed the impact of HICT on athletes’ physical fitness. The quality of included studies was assessed using the PEDro scale, and data synthesis was conducted to summarize findings on various physical fitness components.
Results: The review included 13 studies, highlighting HICT’s positive effects on muscle strength, endurance, flexibility, balance, power, body composition, and cardiovascular endurance. Improvements were noted in neuromuscular efficiency, muscle power, coordination, and cardiovascular fitness, which are crucial for athletic performance. However, the review also identified variability in training adaptations and the need for sport-specific exercises to maximize the benefits of HICT for speed and power enhancements.
Conclusions: HICT is a versatile and effective training modality that can significantly improve various aspects of athletes’ physical fitness. Incorporating targeted, sport-specific exercises into HICT programs could further optimize performance enhancements. Despite promising findings, the review acknowledges methodological heterogeneity among studies and calls for further research to refine HICT protocols for athletes.

Abstract
Background of the Study. Physical fitness is crucial for athletes, enabling them to endure rigorous training and meet competitive demands effectively. It encompasses both health-related attributes, such as cardiovascular endurance and muscular strength, and skill-related components like agility and speed. Various training methods, including circuit training (CT), have been explored to enhance fitness levels among athletes. Despite the growing popularity of CT in various sports, comprehensive research on its effects on athletes’ physical fitness has been limited.
Aim. The present review aims to clarify the effects of CT on physical fitness among team sports Athletes.
Material and Methods. In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) Statement guidelines, the systematic search of PubMed and Google Scholar databases was undertaken on the 28th of August, 2023, to identify the reported studies, using a combination of keywords related to CT, physical fitness, and athletes. Of the 566 studies, only 18 articles met all eligibility criteria and were included in the systematic review. The assessment was performed on the Pedro scale, and the study quality included in the eighteen studies was fair (ranging from 5 to 6).
Results. The results showed that speed (n = 12) was the aspect of physical fitness studied in CT interventions, followed by muscular strength (n = 10), power (n = 13), balance (n = 2), body composition (n = 2), agility (n = 14), flexibility (n = 5), muscular endurance (n = 7), and cardiovascular endurance (n = 8). Existing evidence concludes that CT significantly impacts speed, muscular strength, power, balance, flexibility, agility, body composition, and cardiovascular endurance.
Conclusions: The CT method is one of the ways of physical fitness training aiming at general development, which includes all the physical aspects. Furthermore, there is still limited numbers of evidence showing the effect of CT on agility, body composition, and speed.
