Abstract: La falta de control de la magnitud de la carga de entrenamiento, fundamentalmente la intensidad, es una de las principales limitaciones a la hora de la toma de decisiones para desarrollar programas de ejercicios de estabilización del tronco (ET). Tradicionalmente la intensidad se ha establecido en ... Ver más The lack of control of the training load magnitude, mainly the intensity, is one of the main limitations when making decisions to develop trunk stability (TS) exercise programs. Traditionally, intensity has been established according to the personal criteria of the professionals who prescribe and conduct the programs, criteria that are not usually described in experimental studies and that have generally not been validated or subjected to evaluation. Based on these limitations, the studies carried out in this Doctoral Thesis analyzed different criteria and tools to facilitate decision-making during the establishment of the intensity of the main TS exercises and their progression throughout the training process. In this sense, study 1 showed a high inter- and intra-evaluator agreement through the use of observational screening guidelines based on the assessment of the participants' difficulty to keep the body aligned and to limit trunk movement during the execution of front bridge, dorsal bridge, side bridge and bird-dog exercises. To our knowledge, this is the first study that has analyzed the reliability of observational screening guidelines for the prescription of the TS exercise intensity. To develop objective criteria for TS exercise prescription, diagnostic performance curves (known as ROC curves) were also performed in study 1 with the aim of analyzing the relationship between expert rater ratings and pelvic accelerations (measured by smartphone accelerometry) as an indicator of exercise intensity. This analysis made it possible to establish pelvic acceleration thresholds for the referred exercises that could represent the minimum intensity levels necessary to proaccelerometry was used to establish intensity progressions of different variations of frontal bridge, dorsal bridge, lateral bridge and bird-dog exercises in young physically active males. The data obtained indicates that performing long bridges (with knees extended) instead of short bridges (with knees bent and resting on the floor), reducing the number of support points, supporting part of the body weight on unstable surfaces (hemisphere ball and fitball) and the movement of the elevated limbs are criteria to be taken into account when aiming to increase the intensity of these exercises. Finally, the data obtained also showed the need to individualize the prescription of TS exercise progressions according to the lumbo-pelvic postural control level. Therefore, overall, studies 1 and 2 present relevant information for decision making by physical exercise and health professionals when designing programs aimed at improving TS in young physically active individuals.duce adaptations in TS in young physically active individuals. On the other hand, in study 2, smartphone accelerometry was used to establish intensity progressions of different variations of frontal bridge, dorsal bridge, lateral bridge and bird-dog exercises in young physically active males. The data obtained indicates that performing long bridges (with knees extended) instead of short bridges (with knees bent and resting on the floor), reducing the number of support points, supporting part of the body weight on unstable surfaces (hemisphere ball and fitball) and the movement of the elevated limbs are criteria to be taken into account when aiming to increase the intensity of these exercises.
