Effects of Small-Sided Games Versus Sprint Interval Running on Aerobic Capacity and Training Load in Elite Football

Purpose of the Study: This study aimed to compare the physiological and performance-related effects of two different training methods in elite football players: supramaximal interval running (SIR) and small-sided games (SSG). Who Can Participate: Forty professional male football players (excluding goalkeepers) from the top two leagues in Turkey participated in this study. Participants were required to have no injuries or health problems that could affect their performance. How the Study Will Work: The study was conducted over a six-week preseason preparation period for the 2023-2024 season. Participants were randomly assigned to either the supramaximal interval running (SIR) group or the small-sided games (SSG) group. Both groups trained three times a week. Before and after the intervention, measurements such as maximal aerobic speed (MAS), total running distance, blood lactate levels, body composition (fat mass), and heart rate were taken. Potential Benefits and Risks: Both training approaches resulted in significant improvements in body weight, fat mass, running distance, and aerobic capacity. The information gained from this study could help determine the most effective training methods for elite football players. Since the study is similar to a standard training program, no serious risks are expected. Results: This study found that both supramaximal interval running (SIR) and small-sided games (SSG) training methods improved the physiological and performance outcomes of elite football players. However, the SIR protocol was found to be associated with more pronounced gains in aerobic capacity, anaerobic markers, and body composition. These findings emphasize the benefit of SIR during a short preseason preparation period. The results of the study can help in developing training programs tailored to individual needs and performance goals.
