True or False: Changes in body composition and mood swings can indicate the use of performance-enhancing substances.

The statement that changes in body composition and mood swings can indicate the use of performance-enhancing substances is accurate. Performance-enhancing substances, such as anabolic steroids, can lead to notable physical changes, including increased muscle mass or alterations in fat distribution. These substances can cause significant shifts in hormonal levels, leading to mood swings, irritability, and other psychological effects.

Recognizing these signs is crucial for coaches, trainers, and athletes themselves, as they can serve as indicators of potential substance use that could have detrimental effects on health and sports integrity. Awareness of these possibilities plays a vital role in promoting a fair and healthy athletic environment, and it underscores the importance of education regarding the consequences of using such substances.
