The critical power (CP) concept has been widely utilized in the literature in order to analyze the power-duration relationship during exercise. Many authors have been studying the factors that may alter the parameters (CP; work done above CP, or W') of this relationship, such as pacing techniques, modifications in the glycogen pool, alterations on fosfate-creatine levels, lactate resistance, exercise type and training status. Therefore, CP and W' seems to be important factors of performance of athletes in exercises with different durations and intensities and, thereby, it might be of great value to trainers to use the PC model in order to evaluate training effects in their athletes and even as a performance predictor. The purpose of the present study was to review and to discuss the previously published papers that analysed the effects of aerobic or resistance training protocols on W' and CP, or its correspondents on running (D' and critical velocity, or CV, respectively) in athletes and untrained individuals. Were considered for this study original papers, literature reviews, master dissertations and books which discussed the theme described above. Were considered three electronic databases for this study: PubMed®, SportsDiscuss® and WebOfScience®, and their publications from January 1980 to July 2018. The keywords used in the searching process were: critical power, W', strength training and aerobic training, in both Portuguese and English. The studies were then selected by title, abstract and a first full reading. The remaining studies were then reviewed and discussed in the present study. On total, seventeen papers were discussed, among which eleven involved aerobic training only, five analyzed strength training only and one involved both types of training. All studies related the aerobic or strength training with alterations in the parameters of the power-duration relationship. After the present study's...
