A fasting plasma glucose level greater than 100 mg/dL specifically indicates a state of prediabetes. This condition implies that blood sugar levels are elevated but not high enough to meet the criteria for a diabetes diagnosis, which requires a fasting plasma glucose of 126 mg/dL or higher.

Prediabetes serves as a critical warning sign and provides an opportunity for intervention before the progression to type 2 diabetes occurs. It signals that the body's ability to manage glucose effectively is compromised, although there is still a window of opportunity for lifestyle changes, such as improved diet and increased physical activity, to help reverse this trend.

Understanding these diagnostic thresholds is essential for personal trainers working with clients, as they can guide appropriate training and lifestyle modifications for individuals at risk of developing diabetes.
