AB  - Our aims were to compare physiological parameters from the laboratory environment 
      (LaB) and simulated goalball games (GaM), test relationships between 
      physiological parameters in the laboratory and game technical performance (GTP), 
      and examine the associations between physiological and technical responses during 
      games. Seven elite athletes from the Brazilian National Team performed in LaB 
      environment; (i) an incremental test to determine peak oxygen consumption 
      (O(2PEAK)), its corresponding speed, and peak blood lactate concentration and 
      (ii) submaximal and supramaximal efforts to estimate maximal anaerobic 
      contribution (AnC). In GaM condition, simulated games were also performed to 
      determine physiological responses throughout the game, and to analyze the GTP 
      (number of throws, defenses, recovery, and density of actions). No correlations 
      (unclear) were found between laboratory and games analyses for O(2PEAK) [47.3 
      (17.2) vs. 25.8 (18.2) mL⋅Kg(-1)⋅min(-1)], peak blood lactate concentrations 
      [10.2 (5.4) vs. 2.0 (0.7) mM], and total AnC [21.0 (14.0) vs. 4.8 (6.1) mL 
      Kg(-1)]. O(2PEAK) in the laboratory condition presented very likely correlations 
      with throw and recovery frequency in games (r = -0.87 and confidence interval 
      [CI] = 0.41; r = -0.90 and CI = 0.35; respectively). Oxygen consumption remained 
      above baseline while blood lactate concentration remained unchanged during the 
      games. The very likely correlation between anaerobic alactic contribution and 
      action density (r = 0.95 and CI = 0.25) highlights the importance of the alactic 
      metabolism. In general, our study demonstrates that goalball can be characterized 
      as a high-intensity intermittent effort, where athlete performance is based on 
      aerobic metabolism predominance while determinant actions are supplied by the 
      anaerobic alactic metabolism. Specifically, higher values of LaB vs. GaM 
      highlighted the need for standardization of specific protocols for goalball 
      evaluation, mainly for the reproduction of ecologically valid values. In 
      addition, O(2PEAK) correlated with recovery frequency in the LaB condition, 
      demonstrating that passive or low-intensity recovery between actions is 
      fundamental to maintain performance.
