🟠 Moderate Evidence
A new study published in peer-reviewed sports science research shows that creatine supplementation improves the ability of young basketball players to perform simultaneous motor and cognitive tasks with measurably lower physiological strain. During a dual-task test combining dribbling with mental arithmetic, adolescent athletes who received creatine loading demonstrated faster dribbling speed, enhanced passing accuracy, and improved shooting performance—all while maintaining lower heart rates and reporting reduced perceived effort.
Key takeaways
- Creatine loading (0.3 g/kg/day for 5 days) enhanced dribbling speed, passing accuracy, and shooting performance in 12–14-year-old basketball players
- Young athletes performed dual cognitive-motor tasks with significantly lower heart rate and perceived exertion after creatine supplementation
- The finding suggests creatine may improve how adolescent athletes manage cognitive load during sport-specific motor tasks
- Results point to a potential ergogenic effect in youth sports, though safety and long-term use in developing athletes require further investigation

Understanding the Dual-Task Paradigm
The study employed a dual-task methodology that mirrors real-world basketball demands: athletes dribbled while solving mental arithmetic problems simultaneously. This experimental design captures the cognitive load that young players face during actual competition, where decision-making, spatial awareness, and ball handling must occur in parallel. Research into sports cognition has increasingly adopted such dual-task protocols to measure how athletes allocate attentional resources under realistic competitive conditions.
The creatine intervention—0.3 grams per kilogram of body weight daily for 5 days—follows a standard loading protocol established in sports science. According to prior research on creatine kinetics, this dosage rapidly elevates muscle phosphocreatine stores, which serve as an immediate energy buffer for high-intensity muscle contractions. The improvement across multiple performance metrics—not only motor skill but also reduced physiological strain—suggests a systemic benefit to cognitive-motor integration.
Performance Gains Across Motor and Cognitive Domains
The results demonstrated measurable improvements in three primary motor outcomes. Dribbling speed increased, passing accuracy improved, and shooting performance enhanced following creatine loading compared to placebo. Critically, these gains occurred under cognitive load—the simultaneous mental arithmetic task—which is the more demanding scenario. This finding is noteworthy because cognitive interference typically impairs motor performance in young athletes, yet creatine appeared to attenuate this interference effect.
Equally significant were the physiological markers. Heart rate decreased and perceived exertion dropped in the creatine group during the dual-task test. Lower heart rate during the same cognitive-motor workload indicates improved cardiovascular efficiency, while reduced perceived exertion suggests that the task felt subjectively easier despite maintained or improved performance. This dissociation between effort perception and output is consistent with enhanced cerebral energetics from elevated phosphocreatine availability. Clinical evidence on creatine has long supported its role in brain energy metabolism, though applications in youth athletics remain an emerging area.
Implications for Youth Sports Science and Policy
The findings raise important questions for coaches, sports medicine practitioners, and sports nutrition specialists working with adolescent athletes. If creatine genuinely improves simultaneous motor-cognitive performance with lower physiological cost, it could optimize training efficiency and reduce injury risk by allowing athletes to practice skill execution under more challenging conditions without excessive fatigue. For young athletes and their families, this suggests a potential evidence-based supplement option, though dosing, timing, and individual variation remain open questions.
However, the study evaluated only acute loading over 5 days in a single session. Long-term safety and efficacy in developing bodies—particularly regarding renal function, growth, and hormonal effects—require longitudinal investigation. The International Society of Sports Nutrition has acknowledged creatine’s safety in adults, but paediatric data remain limited. Quality and safety considerations specific to adolescent use warrant careful attention before widespread recommendation in youth sports programmes.
Next Steps and Research Directions
Future studies should extend follow-up duration beyond acute loading to assess chronic supplementation effects, examine different age groups within the 12–14 range, and investigate whether improvements persist with continued use or show tolerance development. Research into sex-specific responses, baseline nutritional status, and sport-specific skill transfer would strengthen the translational value of these findings. Additionally, mechanistic studies examining brain energy metabolism, neurotransmitter function, and phosphocreatine concentrations during dual-task performance could clarify how creatine achieves these cognitive-motor benefits.
In a controlled dual-task test combining dribbling with mental arithmetic, adolescent basketball players who received creatine loading (0.3 g/kg/day for 5 days) demonstrated faster dribbling, better passing accuracy, improved shooting, and lower heart rate and perceived exertion compared to placebo.

What this means
Frequently asked questions
Is creatine safe for 12–14-year-old athletes?
The International Society of Sports Nutrition has designated creatine as safe for adults at recommended doses, citing no adverse effects on kidney or liver function in healthy individuals. However, long-term safety data in adolescents—particularly regarding renal development, growth patterns, and hormonal effects—remain limited. Any supplementation in youth athletes should be supervised by qualified medical or sports nutrition professionals and preceded by assessment of baseline health status.
How does creatine improve both motor skill and reduce fatigue perception?
Creatine acts as a rapid energy buffer in muscle and brain cells by replenishing adenosine triphosphate (ATP) during high-demand tasks. Enhanced phosphocreatine availability may allow athletes to sustain cognitive-motor performance with less metabolic strain, explaining both improved skill execution and reduced heart rate and perceived exertion. This mechanism is most pronounced during short, intense efforts like dual-task protocols.
Can these findings be generalised to other youth sports?
This study specifically examined basketball players aged 12–14 during a dual-task test. Whether creatine’s benefits transfer to other sports, age groups, or performance domains (endurance, strength, team sports with different cognitive demands) requires separate investigation. Coaches and athletes in other sports should not assume identical effects without sport-specific evidence.
As youth sports science continues to integrate cognitive-motor assessment into performance evaluation, supplements like creatine that target both domains warrant rigorous study. The current findings suggest promise, but responsible translation into youth athletic practice demands a commitment to long-term paediatric safety monitoring, individualised medical clearance, and transparent communication about evidence gaps. Coaches, parents, and athletes should approach any supplementation decision with the same evidence-based rigour that elite sports medicine now demands.
