Many athletes use anabolic-androgenic steroids (aas) for physical enhancement but the magnitude of these gains and associated adverse effects has not been rigorously quantified, at least in the human setting. Here, we present the results of one systematic review of all published studies that involved high-intensity sprint training in male and female elite athletes and to our knowledge, no study has reported any adverse effect on performance from using high-intensity sprint training in females. Despite the limited studies available, some recent evidence suggests that female high-intensity sprint training may improve sports performance, possibly due to the improved endurance capacity [13,14], organon deca durabolin 100mg. This increased endurance capacity is related to the training-induced hypertrophy of skeletal muscle [15-17]. Therefore, we studied the effects of high-intensity sprint training on endurance capacity in female athletes and concluded that these findings suggest that prolonged endurance training may promote the development of anabolic-androgenic (AAS) and muscle hypertrophy in humans, resulting in enhanced endurance performance without affecting body weight and fat mass gains, psychopathology athletes anabolic-androgenic in use and steroid.Methods This systematic review consisted of a comprehensive search of the Cochrane Reviews, MEDLINE and EMBASE databases, and CINAHL. We searched for publications that addressed the topic of high-intensity sprint training in female athletes in 2005 and 2007. We restricted the search to the following titles and abstracts (see Table 1): Endocrinology, Sports Medicine, Exercise and Sport Medicine (1999-2003), trenbolone enanthate stay in your system. The search parameters included (A), (B), (C) and (D), anabolic-androgenic steroid use and psychopathology in athletes. Articles that appeared in this review met the following criteria used for research on a large number of athletes : · High intensity (200-210 km·h−1), prolonged sprints, training duration longer than 1 week for females or longer than 1 week for males or · Female only, · Subject was female but subject was male or · Subject was in her early 20s or older and · Studies reported data on acute, chronic, and/or long-term effects on performance and body density and body composition (body mass index and body fat). Studies were excluded if the study: (i) reported no outcome in female athletes, buy anabolic steroids online visa. Further information regarding the review process is available elsewhere . Table 1.

To the best of our knowledge, we were the first to examine the effect of high-intensity interval training on performance in female athletes, organon deca durabolin 100mg.
