Different Forms Of Swimmers’ Final Weeks Pre-Competition Preparation, Kamil Sokolowski, Marek Strzala, Arkadiusz Stanula
Baltic Journal of Health and Physical Activity
The pre-competition training phase is a period that precedes the main competition. Combined training phases of overload training (OT) and taper (TP) create the most popular pattern of final form preparation among the swimmers despite the methodology difficulties faced by coaches. In the IPC, the duration and training load were strictly set. The main purpose of training in the IPC is to cause a substantial supercompensation effect by the high volume and capacity of the training. However, high volume and intensity fluctuations typical of the IPC may cause performance regression due to overtraining and exhaustion. The main aim of the …
