Final answer:
The current evidence is insufficient to make formal recommendations for prescreening for cardiovascular complications in resistance training, with the need for more rigorous studies to understand its benefits and potential risks.
Step-by-step explanation:
The question asks whether there is enough evidence to justify prescreening for cardiovascular (CV) complications before participating in resistance training due to its rising popularity. While resistance training is gaining attention, the current body of research, such as the studies mentioned in references, does not provide sufficient evidence to conclude whether resistance training leads to improvement in strength or is associated with an increase in CV complications. It is crucial to consider that confounding variables, such as the use of software or different exercise routines, can affect outcomes, and hence, it is difficult to draw reliable conclusions without further investigation. Various studies, including those focused on cancer survivors, point to the need for more rigorous and controlled trials in understanding the relationship between resistance training and health outcomes. It should also be noted that expert bodies like the IOC indicate that there is no strong evidence to suggest that certain supplements can significantly enhance training outcomes.
