The most effective means for improving performance involves prolonged systematic exercise training. Increases in power and endurance of over 50% have been achieved in previously sedentary individuals through conditioning and adherence to optimal nutritional diets. Another potential means for enhancing performance involves taking supplements or “ergogenic” aids. It has been estimated that these supplemental aids do not usually result in more than a 7% improvement in performance, especially when given to untrained individuals. Serious, well-trained athletes, however, usually maintain their fitness at near their maximum tolerance limits. Why such competitors would want to utilize supplements for any potential benefits these aids might provide to further improve physical performance is, therefore, understandable.A wide variety of commercial supplements are available, but no well designed experiments have been performed to prove that they provide significant benefit to elite athletes. The following study was undertaken to evaluate a popular protein supplement by monitoring power output generated by peak conditioned athletes using a knee extension/flexion exercise machine in a randomized controlled crossover model. Plasma and urine amino acid concentrations were determined and based on amino acid disappearance profiles (reflecting utilization), an enriched protein supplement was formulated that resulted in significantly improved power and endurance for these athletes. METHODS -- Preliminary An exercise protocol was established involving alternating knee extensions and flexions using the OMITRONR apparatus. Participants were asked to use maximum effort with each motion. The resistance was adjusted on the apparatus to setting #8 or #9 (consistent per athlete per testings) to allow a complete range of motion so that multiple repetitions could be performed. VO2 max was 60%-70%, indicating exercise of moderate intensity. The set number of repetitions followed by a rest period constituted on cycle. Multiple cycles were repeated for the exercise testing. Power output was recorded for each extension and flexion. The apparatus was calibrated prior to each use. next |
