ABSTRACT
Training variables can be broken down into frequency, intensity, volume, and duration. Frequency is how often you train, intensity is the effort that you train at, volume is how much work performed, and duration is how long it takes. Training volume has received the most attention in the literature and it appears that training once per day is as effective as training twice per day with regard to physical conditioning and subsequent race times during competition in competitive swimmers. Those that trained twice per day over the course of their four-year collegiate career saw similar improvements as those that trained once per day. However, aside from swimming (which relies heavily on muscular endurance) which is assessed by race times, there is a good rationale for training twice per day in competitive amateur wrestlers. Strength acquisition and skill acquisition through drilling can be done in a second practice in competitive wrestlers while the primary practice deals with live wrestling. Another reason for training twice per day would be to obtain additional aerobic training during the second practice. However, the Coach and Athlete must be cognizant of overtraining while training twice per day and should monitor variables that would be indicative of overtraining (see “Physiological Assessment and Determination of Overtraining” chapter).
