OBJECTIVE: Athletes undergoing weight reduction are recognised as being more prone to infection. Few studies exist for athletes on the weight reduction-mediated changes in neutrophil function and related activities such as reactive oxygen species (ROS) production capability, phagocytic activity (PA) and serum opsonic activity (SOA). METHODS: 16 Japanese female university judoists were examined in the early morning of the first day (pre-values) and the last day (post-values) of a 20-day pre-competition training period. Of the 16 subjects, 8 needed to reduce weight (WR group) and the other 8 did not (control group). The parameters assessed were the neutrophil count, serum immunoglobulins and complements, myogenic enzymes, ROS production capability, PA and SOA. RESULTS: Comparing the post-values with the pre-values, ROS production significantly increased in both groups (p<0.01 for both). PA significantly decreased in the WR group (p<0.05); it also decreased in the control group but the decrease was not significant. SOA significantly increased in the control group (p<0.05), but showed no significant change in the WR group. CONCLUSIONS: The changes in the WR group were probably a direct consequence of the weight-reduction regimen coupled with the exercise regimen, suggesting that neutrophil parameters (ROS production, PA and SOA) had tended to deviate from their typical compensatory changes to maintain immune system homoeostasis.
Football hooliganism is a world phenomenon and an everyday matter. Society spends a lot of money to prevent and control it. We need to know what hooligans think in order to anticipate their actions and prevent their violent behaviors. In this paper, I propose a theory of the hooligan's conscious mind, by analyzing the thinking of a real Italian hooligan who was my patient. I will show that violent behaviors of hooligans are not unconscious, because the mental states (both beliefs and goals) of hooligans are explicitly represented in their mind. In contrast, I will suggest that both supporting and fighting are planned (i.e., goal directed), because "recognized supremacy" is explicitly represented as the ultimate goal. In fact, hooligans support and fight in order to be recognized as good hooligans, i.e. as good supporters as well as good fighters.
