In August 2018 researchers from Tunisia and France published the results of their study to compare the effect of 2 training programmes, high-intensity interval training and moderate-intensity continuous training, on haematological biomarkers in 16 healthy active young men, aged 18-20 years. The individuals were requested to undertake one of the two training programmes for a 9-week period. Aerobic capacity and haematological biomarkers were assessed before and after completion of the training programmes. Results showed that moderate-intensity continuous training produced a significant improvement in haematological biomarkers when compared to high-intensity interval training. The moderate-intensity continuous training appeared to increase the number of immune cells, whereas the opposite occurred following the high-intensity interval training.
