Bottom Line: VO2max and anaerobic mean power in IJ (P < 0.05) and anaerobic power in RJ (P < 0.05) were significantly increased after 12-week training compared to CG.There was significantly higher changes in epinephrine of RJ compared to IJ at 30-minute recovery (P = 0.045).Along with increased physical stress, all groups showed reduced trend of IgA; however, there was no group difference based on different training methods.

ABSTRACT

Background: It has been reported that high intensity long term training in elite athletes may increase risk of immune function.

Objectives: This study is to examine training effects on immunoglobulin and changes of physiological stress and physical fitness level induced by increased cold stress during 12-week winter off-season training in elite Judoists.

Patients and methods: Twenty-nine male participants (20 ± 1 years) were assigned to only Judo training (CG, n = 9), resistance training combined with Judo training (RJ, n = 10), and interval training combined with Judo training (IJ, n = 10). Blood samples collected at rest, immediately after all-out exercise, and 30-minute recovery period were analyzed for testing IgA, IgG, and IgM, albumin and catecholamine levels.

Results: VO2max and anaerobic mean power in IJ (P < 0.05) and anaerobic power in RJ (P < 0.05) were significantly increased after 12-week training compared to CG. There was no significant interaction effect (group × period) in albumin after 12-week training; however, there was a significant interaction effect (group × period) in epinephrine after 12-week training (F (4, 52) = 3.216, P = 0.002) and immediately after all-out exercise and at 30-minute recovery (F (2, 26) = 14.564, P = 0.008). There was significantly higher changes in epinephrine of RJ compared to IJ at 30-minute recovery (P = 0.045). There was a significant interaction effect (group × period) in norepinephrine after 12-week training (F (4, 52) = 8.141, P < 0.0001), at rest and immediately after all-out exercise (F (2, 26) = 9.570, P = 0.001), and immediately after all-out exercise and at 30-minute recovery (F (2, 26) = 8.862, P = 0.001).

Conclusions: Winter off-season training of IJ increased physical fitness level as well as physical stress induced by overtraining. Along with increased physical stress, all groups showed reduced trend of IgA; however, there was no group difference based on different training methods.

Mentions: There was a significant interaction effect (group × period) in weight (P = 0.011), % fat (P = 0.03), HRmax (P = 0.018), and anaerobic mean power (P = 0.003). However, there was no significant interaction effect (group × period) in VO2max and anaerobic peak power. There was no significant interaction effect (group × period) in albumin after 12-week training; however, there was a significant interaction effect (group × period) in epinephrine after 12-week training (F (4, 52) = 3.216, P = 0.002) and immediately after all-out exercise and at 30-minute recovery (F (2, 26) = 14.564, P = 0.008). There was significantly higher changes in epinephrine of RJ compared to IJ at 30-minute recovery (P = 0.045). There was a significant interaction effect (group × period) in norepinephrine after 12-week training (F (4, 52) = 8.141, P < 0.0001), at rest and immediately after all-out exercise (F (2, 26) = 9.570, P = 0.001), and immediately after all-out exercise and at 30-minute recovery (F (2, 26) = 8.862, P = 0.001). There was a significant increase in group change of IJ compared to CG at rest after 12-week training (P = 0.014) and there was a significant decrease in group change of IJ compared to CG (P = 0.005) and RJ (P = 0.006) immediately after all-out exercise followed by 12-week training. There was a significant increase in group change of IJ compared to CG at 30-minute recovery followed by 12-week training (P = 0.036) (Figure 1). There was no interaction effect (group × period) in IgA, IgG, and IgM after 12-week training (Figure 2). During 12-week training period, there was no significant group difference in nutritional risk index (Figure 3).
