Personal trainers are encouraged to use this OTS Indicator Checklist to help identify or prevent OTS in clients. Although this list was developed from scientific research, there currently is no research consensus on how many of these factors must be present (and to what degree) to confirm OTS.
PERFORMANCE AND FATIGUE INDICATORS
These may be symptoms of OTS:

Conducting primary research studies on the causes of overtraining is difficult because it’s unethical to induce overtraining syndrome, which can damage a person’s performance for months. Kreher and Schwartz (2012) reviewed previously published overtraining research and summarized seven hypotheses (see Figure 5) for mechanisms that cause overtraining syndrome.

A client who develops overtraining syndrome needs to return to a healthy state as fast as possible. While there is no magic cure for overtraining, these 10 preventive strategies for nonfunctional overreaching and overtraining syndrome, from Kreher and Schwartz (2012), should prove helpful:

Personal trainers regularly monitor clients’ physiological and psychological responses to progressive overloads during a training program. After sufficient recovery from training fatigue, the body compensates by building strength and improving performance. However, chronic overtraining often leads to physiological and psychological symptoms that impair performance and delay full recovery for weeks or more (Meeusen et al. 2013).

Can New Research Prevent an Age-Old Paradigm?
Heart rate variability (HRV) is a reliable marker of physiological factors that directly affect the rhythms of the heart (Acharya et al. 2006). Acharya and colleagues explain that HRV reflects the heart’s ability to adapt to changing circumstances—stress, exercise and disease—by balancing the regulation of the autonomic nervous system, which controls bodily functions such as breathing, heart- beat and digestion.
