AIM: The aim of this study was to verify the responses of muscle damage (creatine quinase and lactate dehydrogenase), haematological (red blood cell count, haemoglobin and haematocrit), immunological (white blood cell count, number of neutrophils and lymphocytes) and psychological markers (RESTQ-SPORT) to long-term training load in futsal players during preliminary season.
METHODS: Thirteen futsal players (26.9 ± 5.4 years, 73.8 ± 4.7 kg) participated in this study. Total weekly training load (TWTL) of four mesocycles (M1, M2, M3 and M4) was calculated by the session Rating of Perceived Exertion method. At the end of each mesocycle, muscle damage, haematological, immunological and psychological markers were analysed.
RESULTS: Using repeated measures ANOVA, adjusted according to the Bonferroni test, it was observed that the third mesocycle showed lower TWTL, red blood cell count and haematocrit were higher in M3 than M1 and M4 and haemoglobin was higher in M3 than M1 and M2. Moreover, some RESTQ-SPORT scales showed changes during the mesocycles, however without relationship with the TWTL. Pearson’s correlation test showed that there were moderate correlations between some scales of RESTQ-SPORT and muscle damage markers.
CONCLUSION: Therefore, coaches should consider the use of haematological markers for a longitudinal approach to monitor training load in team sports.
