Four weeks of training with different aerobic workload distributions – Effect on aerobic performance

Abstract Although numerous authors have studied the effect of different training procedures on athletes resistance performance, there are no studies on how the improvement of aerobic resistance is affected by the distribution of training loads. This research sets out to analyse the effectiveness on aerobic activity of distributions with a constant load (CON) and with increments in intensity (INC) over a 4-week period. A total of 30 athletes took part in the analysis (38.7±9.8 years; 174.7±6.5 cm; 72.0±9.8 kg). They were divided into 3 groups of 10 each. One group followed a training plan with a CON distribution and another with an INC distribution. Both groups performed at the same volume and intensity, the only difference between them being the distribution of load over the 4 weeks. The third group trained with a free load distribution during this time. Improvement in V˙O2max and ventilatory thresholds (VT1 and VT2) was analysed before and after the 4-week training period. There was no modification of the V˙O2max in any of the training programmes. The FRE and INC groups showed a significant decrease (p<0.05) in their V˙O2 in VT1, and in the CON group there was a significant reduction (p<0.05) in heart rate in VT2. These results show how training periodisation produces different improvement on performance and demonstrate the effectiveness of periodisated programmes, because periodisated programmes obtain equal or higher adaptations with lower training volumes than non-periodisated programmes.

Introduction and objectives Several authors have studied the influence of exercise on the nervous system and cognitive performance in untrained subjects and different stimuli such as intense anaerobic exercise to exhaustion, and submaximal endurance exercises using the Flicker Fusion Threshold (UFF). The effect on the central nervous system stimulation in repeated sprints testing has not been studied. The aims of this work are study the changes in Flicker Fusion thresholds before and after a test of repeated sprints (RSA) in soccer players, to evaluate the fatigue of the central nervous system.
