[en] Background: During the last years, triathlon has enjoyed a considerable increase in its practise. As in all sports, there is always a risk of injury. One of the most common among women is patellofemoral pain syndrome, which has a prevalence of 22,7% in amateur female athletes. The literature found in relation to the prevention of this syndrome is very scarce. Therefore, trying to meet the need for scientific evidence about this topic, a research project that addresses this field is proposed. Objective: To determine the efficacy of a therapeutic exercise programme in reducing patellofemoral syndrome risk factors in female triathletes, thus trying to reduce its incidence. Methods: A randomized, controlled, prospective and single blind clinical trial will be carried out. This will be carried out at the Facultade de Fisioterapia of A Coruña and at the sports installations of the clubs that collaborate with the project. Participants will be divided into a control group and an intervention group, which will carry out the prevention programme, supervised at all times. This will consist of ankle flexibility exercises, strengthening of the lower limb and abdominal musculature, which, in turn, improve motor control. It will be done for a total of 3 months, with a frequency of 3 days per week. Each session will last approximately 45 minutes. The control group, meanwhile, will continue to do their usual training. Before and after the prevention programme, assessment will be carried out on all the participants, where data related to risk factors of patellofemoral pain syndrome will be collected.

[gl] Introdución: Durante os últimos anos o tríatlon gozou dun aumento considerable na súa práctica. Como en todos os deportes, sempre existe o risco de sufrir lesións. Unha das máis frecuentes entre as mulleres é a síndrome femoropatelar (SFP), que conta cunha prevalencia do 22,7% en atletas femininas amateus A literatura que se atopou en relación á prevención desta síndrome é moi escasa. Polo que, tratando de suplir a necesidade de evidencia científica en relación a este tema, proponse un proxecto de investigación que aborde este campo. Obxetivo xeral: Determinar a eficacia dun programa de exercicio terapéutico na reducción dos factores de risco da SFP en mulleres triatletas, tratando desta maneira, de reducir a súa incidencia. Material e método: Levarase a cabo un ensaio clínico aleatorizado e controlado, prospectivo e cego simple. Este será realizado na Facultade de Fisioterapia da Coruña e nas instalacións deportivas dos clubes que colaboren co proxecto. As participantes serán divididas en grupo control (GC) e grupo intervención (GI), que realizará un programa de prevención, supervidado en todo momento. Este constará de exercicios de flexibilización do tobillo, fortalecemento do membro inferior e da musculatura abdominal, que, a súa vez, melloran o control motor. Realizarase durante un total de 3 meses, cunha frecuencia de 3 días a semana. Cada sesión terá unha duración aproximada de 45 minutos. O GC, mentras tanto, continuará realizando os seus adestramentos habituais. Previa e posteriormente ao programa de prevención, levaranse a cabo as valoracións en todas as participantes, onde se recollerán datos relacionados cos factores de risco da SFP.
