Common indicators of overtraining include persistent fatigue, decreased performance, disrupted sleep patterns, and increased susceptibility to injuries. Athletes may also experience mood swings, irritability, and a lack of enthusiasm for training. Physically, symptoms might manifest as chronic muscle soreness, elevated resting heart rates, and changes in appetite. It is crucial to recognize these signs early, as overtraining can lead to severe consequences for both physical and mental health. Implementing adequate rest and recovery periods, along with adjusting training intensity, can help mitigate these issues and promote long-term success.
