Influence of Core Training on Fatigue, Balance and Performance in Adolescent Football Players
Influence of Core Training on Fatigue, Balance and Performance in Adolescent Football Players (Randomized Controlled Trial)
Background:
Adolescent football players are exposed to high physical and psychological demands due to intensive training, frequent matches, travel, and limited recovery time. These factors can lead to early fatigue, reduced balance, and lower technical performance, all of which may increase the risk of non-contact injuries. The muscles of the trunk (core muscles) help stabilize the spine and pelvis, transfer forces between the upper and lower limbs, and maintain postural control during sport-specific movements. Weak core stability has been linked to poorer balance, reduced fatigue resistance, and suboptimal performance. Although core training is widely used in sports, there is limited evidence on its combined effects on fatigue, balance, and football-specific performance in adolescent players.
Objectives:
This randomized controlled trial aims to examine whether an 8-week core training program can improve fatigue resistance, balance, and football performance in adolescent football players compared with usual training alone.
Methods:
This is a pre-post, parallel-group randomized controlled trial conducted at Wadi Degla Football Club. Eligible participants are male adolescent football players aged 14-18 years from the 2005, 2006, and 2007 teams, who train regularly (at least 6 hours per week), have a body mass index between 18.5 and 24.9 kg/m², and have been free from lower-limb injury or surgery for at least 6 months. Players with recent major lower-limb injuries, surgery, or irregular training will be excluded.
Participants will be randomly allocated into two groups using computer-generated random numbers: (1) a core-training group, which receives an 8-week structured core exercise program in addition to their usual football training, and (2) a control group, which continues usual football training without additional core exercises. Both groups will be assessed before and after the intervention period. Outcome measures will include fatigue-related performance, static and/or dynamic balance, and football-specific performance tests.
Potential Benefits and Risks:
The study may help clarify whether adding core training to routine football practice can enhance fatigue resistance, balance, and functional performance in adolescent football players and potentially reduce injury risk. The exercises are commonly used in sports settings and are considered low risk for healthy athletes; no significant risks beyond normal football training are anticipated. Participation is voluntary, and players may withdraw from the study at any time without any consequences for their team status or medical care.

Background and Rationale:
Adolescent football players are exposed to increasing physical and psychological demands due to intensive training schedules, frequent competition, and limited recovery. These demands may contribute to early fatigue, impaired balance, and reduced technical performance, potentially increasing the risk of non-contact musculoskeletal injuries. Additionally, growth-related changes and ongoing neuromuscular development during adolescence may further affect movement control and performance consistency.
The core musculature, including the abdominal, lumbar, pelvic, and hip muscles, plays a fundamental role in trunk stabilization, force transmission, and postural control during football-specific activities such as sprinting, cutting, kicking, and landing. Adequate core stability is considered important for maintaining movement efficiency and performance, particularly under conditions of fatigue. Conversely, insufficient core control has been associated with impaired balance and suboptimal functional performance.
Although core training is widely implemented in sports conditioning programs, current evidence regarding its effectiveness in adolescent football players remains limited and inconclusive. In particular, the combined effects of core training on fatigue resistance, balance, and football-specific performance are not well established in this population. Therefore, further research is needed to determine whether integrating structured core exercises into routine football training provides meaningful additional benefits.
Study Design Overview This study is a randomized controlled trial designed to investigate the effects of an 8-week structured core training program in adolescent football players. The intervention is integrated within a real-world club training environment, allowing for practical applicability of the findings.
Participants will be allocated to either a core training group or a control condition involving routine football training. The study follows a pre-post design to evaluate changes over time and to compare outcomes between groups.
Significance:
The findings of this study are expected to contribute to the evidence base guiding training and injury prevention strategies in youth football. Clarifying the role of core training may support coaches, physiotherapists, and strength and conditioning professionals in optimizing performance development and reducing injury risk in adolescent players.
