Background and Study Aim: to evaluate the maximal oxygen uptake (VO 2max) of judoists in consecutive training periods: a) GPP, b) SPP, c) CP.
Material and Methods: Fifteen male judoists aged of 22 ± 7 years took part in this study. Their competition levels varied from departmental (group D, n = 7) to inter-regional (group IR, n = 8) experience. The standing height was measured with a wall-mounted wooden stadiometer. An electronic weighing scale was used to assess the body mass (W) in each period of preparation. The VO2max was measured indirectly using the multistage 20- meters shuttle run test.
Results: The performance level had a statistically significant bearing (p<0.001) of judo competitors weight, but not with the time factor. The pattern of changes in weight in both groups IR and D was different during the training period. We also noticed that the weight of group D members decreased in SP period and increased in CP. We didn’t observed a significant difference of VO2max between group D and IR (95% Tukey HSD intervals are overlapping). The competition level affects significantly the HRmax (p<0.001). Group D presented higher HRmax values in three testing periods (GPP, SP and CP) than IR group. The time factor was close to reach significance level.
Conclusions: The VO2max of judoists varies in consecutive training periods. The HRmax is correlated to the sport level but it less sensitive at workload variations than the HRmax. A moderate aerobic state doesn’t suggest a low judo performance. Tests more specifically linked to judo could be proposed to provide more information about this aspect.
