A multi-year framework for progressively developing physical capacity and sports skills as young athletes mature.
Long-Term Athletic Development (LTAD) refers to a staged approach to training young or developing athletes that sequences the emphasis on movement skill, physical qualities (e.g., speed, strength, endurance), and sport-specific training in line with growth, maturation, and training age rather than chronological age alone. It is commonly used to guide programming decisions such as when to introduce structured resistance training or specialise in a single sport. The specific stage models (e.g., Balyi's windows of trainability) are widely cited in practice but remain contested in the sport science literature, with limited high-quality evidence supporting fixed 'sensitive periods' for adaptation.
