Recent psychophysiological models of endurance performance explained that pacing strategies and exercise-intensity regulation influence cyclists' ability to produce high mean power output (PO) during time trials (TTs). However, the relationships between these pacing strategies and psychological parameters of the athletes remain unknown.
To determine the impact of pacing strategies on cyclists' mean PO during an elite TT championship and to identify the relationships between these pacing strategies and psychological parameters.
Mean PO, projected frontal area, attentional focus, and pleasure were recorded for 9 male cyclists during an official individual TT national championship. Pacing regulations were quantified from PO using the new exposure variation analysis, which determines times spent at adapted PO for optimal constant-pacing strategy (APO) and inaccurate PO for optimal constant-pacing strategy (IPO). Relationships between mean PO, times spent at APO and IPO, and psychological variables were analyzed.
Significant relationships were found between mean PO and exposure variation analysis pacing parameters (r .56-.86, P > .05). Time spent at IPO was negatively related to pleasure during the individual TT (r = -.746, P = .016). Conversely, time spent at APO was significantly related to cyclists' attentional focus (r = .827, P = .006).
Mean PO during elite individual TTs is directly related to athletes' ability to optimally regulate pace throughout the event. This pacing regulation is influenced by attentional focus and pleasure, underlining that coaches and athletes should devote greater attention to these psychological parameters to improve their performances.
最近的耐力表现心理生理学模型解释了，配速策略和运动强度调节会影响自行车手在计时赛（TT）中产生高平均功率输出（PO）的能力。然而，这些配速策略与运动员的心理参数之间的关系仍然未知。
确定配速策略对精英 TT 锦标赛中自行车手平均 PO 的影响，并确定这些配速策略与心理参数之间的关系。
在一次官方的个人 TT 全国锦标赛中，记录了 9 名男性自行车手的平均 PO、投影正面面积、注意力焦点和愉悦感。使用新的暴露变化分析（determines times spent at adapted PO for optimal constant-pacing strategy (APO) and inaccurate PO for optimal constant-pacing strategy (IPO)）从 PO 中量化配速策略，确定在适应 PO 上花费的时间（用于最佳恒定配速策略（APO））和在不准确的 PO 上花费的时间（用于最佳恒定配速策略（IPO））。分析平均 PO 与在 APO 和 IPO 上花费的时间和心理变量之间的关系。
发现平均 PO 与暴露变化分析配速参数之间存在显著关系（r.56-.86，P > .05）。在个人 TT 期间，在 IPO 上花费的时间与愉悦感呈负相关（r = -.746，P = .016）。相反，在 APO 上花费的时间与自行车手的注意力焦点显著相关（r = .827，P = .006）。
在精英个人 TT 中，平均 PO 直接与运动员在整个比赛中优化调节节奏的能力有关。这种配速调节受到注意力焦点和愉悦感的影响，这强调了教练和运动员应该更加关注这些心理参数，以提高他们的表现。
