Filter by:Caffeine is one of the few supplements that have enough scientific evidence to state that can notably improve performance, as different remarkable organizations in the sports nutrition context have classified it as an ergogenic aid with strong evidence regarding its efficacy and that is apparently safe. The beneficial effect of this substance on physical and cognitive performance has been identified in aerobic and anaerobic efforts, including aerobic and muscular endurance, power, or strength. However, it seems that the benefits of caffeine are usually measured only by its effect on performance, while a comprehensive analysis of its impact on other aspects of the movement technique of the exercise is not considered. Therefore, although caffeine generates better performance, a null or negative effect may occur on technique execution. As such, some consequences might arise (e.g., an increase in injury risk or a decrease in energy efficiency). The objective of this randomized controlled trial is to assess the influence of caffeine on certain biomechanical parameters of the technique of physical exercises in circumstances without fatigue and under neuromuscular fatigue. The study hypothesis is that caffeine generates modifications in the technical execution of certain movements in fatigued and unfatigued circumstances due to its physiological effects, which may be beneficial for performance and injury prevention. The participants will have to attend 5 sessions (enrollment, familiarization, control, placebo, and caffeine), at least 7 days apart. In the last 3 sessions, different measurements will be done to their technique while jumping, squatting, and running, without fatigue and with it. Other data will be collected throughout the study to contextualize and analyze in more detail the obtained information.
This research is being performed to characterize the rowing stroke in active and inactive individuals who use a manual wheelchair. The investigators will be looking at muscle activity of four shoulder muscles (upper trapezius, lower trapezius, serratus anterior, and posterior deltoid) and motion of the arms, shoulder blade, and trunk during rowing. This will be done for three rowing conditions (1: adapted rowing ergometer, 2: rowing ergometer from a chair, 3: standard seated row exercise using an elastic band [TheraBand]). The investigators are also looking at shoulder strength, range of motion, quality of life, and community participation.
The purpose of this study is to investigate the additional effects of Short Foot Exercises on pain, biomechanical characteristics and functionality of lower extremity in patients with patellofemoral pain.
