... it should always be remembered that the GPP and SPP always from an interconnected unit. In some cases, the GPP and the SPP may even be concurrent or the GPP may be largely indistinguishable from the SPP (Bondarchuk, 1979).
The GPP is intended to provide balanced physical conditioning in endurance, strength, speed, flexibility and other basic factors of fitness, whereas the SPP concentrates on exercises which are more specific to the particular sport. Characteristically, the GPP may include participation in a variety of different physical activities which provide low intensity, all-around conditioning, with little emphasis on specific sporting skills. Participation in activities such as jogging, swimming, cycling, tennis, or volleyball may be appropriate in this phase for some sports. If the player needs to gain muscle or lose fat, this is regarded as the appropriate period to do so. Sometimes an hypertrophy phase
may be included in the GPP if there is a need for gaining functional muscle bulk. The decision to utilize this type of phase should be based on an assessment of the strength deficit discussed previously (Ch 1 and Fig 1.1)
Sometimes it is important to include very specific SPP-type exercises during the GPP
either to rehabilitate any existing injuries or to eliminate any structural or functional deficiencies or imbalances in physique, posture and neuromuscular skill. It may be also relevant to curtail or eliminate standard types of GPP from the training programme of anyone who is an advanced athlete or has trained regularly for a prolonged period at increasing levels of proficiency. Similarly, the use of GPP-type exercises may be appropriate for brief periods during the SPP to facilitate recovery or prevent stagnation.
