背景與目的：近年來運動場館相關研究大多著重於服務品質及滿意度之議題，對於社會性運動團隊研究著墨甚少，本研究探討羽球館團隊成員消費者團隊氣氛、知覺價值與持續承諾之關係。方法：以台中市私人羽球館團隊成員消費者為研究對象，採立意抽樣方式進行問卷調查，共發放400份問卷，有效回收共334份。以描述性統計、皮爾森積差相關、迴歸分析等方法進行分析。結果：1.羽球館團隊成員消費者知覺到較高的團隊氣氛及較佳的知覺價值，並擁有較高的持續承諾；2.團隊氣氛之「工作團隊」與「社會團隊」能有效正向影響知覺價值四向度與持續承諾二向度，僅在「社會團隊」未能影響知覺價值之「價格功能性」；3.知覺價值之「情感性」、「價格功能性」能有效正向影響持續承諾之「想要的承諾」，而「社會性」、「知識性」能有效正向影響持續承諾之「必須的承諾」。結論：羽球運動團隊經營者除重視團隊氣氛之營造外，應加強成員對該團隊之價值感受，將有助於個體持續參與團隊之意願。

The performance of pitchers has significant impact of winning games in professional baseball. The increased number of pitched balls could result in the decline in subsequent performance, or even lead to injury. However, the scientific evidence for the optimal loading is still lacking. This study analyzed 16383 games from 520 starting pitcher-year from Major League Baseball between 2001 and 2006. The loading was calculated by pitcher abuse point 3, defined by PAP3 = (number of pitch - 100)3; PAP3 =0 if pitch＜100. The loading was categorized into 4 groups according to the accumulated PAP3 in 3 consecutive games: PAP3G1 (0), PAP3G2 (1-375), PAP3G3 (376-3000), PAP3G4 (＞3000). The difference in performance between the previous and subsequent 3 games was calculated. The pitchers were categorized into 4 workload groups according to the median of numbers of pitches in starts, or categorized into 3 pitching types (power, finesse, average). The effect of PAP3 accumulations on the difference between the previous and subsequent performance was analyzed. In all workload and pitching type groups, the ratios of worse performance in SO/PA, fielding independent pitching, and earned run average in the subsequent 3 games were increased as the accumulations of PAP3 increase. In pitchers with different workloads, the ratios of worse performance started to increase at around the medians of their pitch counts. The ratios of worse performance started to increase in PAPG3 in finesse and average pitchers, while they were increased in PAPG4 in power pitchers. This study indicated that the increased numbers of pitches would result in poorer performance in the subsequent games in MLB starting pitchers, regardless of their workloads or pitching types. Different types of pitchers seem to be able to tolerate different workloads. However, PAP3 higher than 3000 in the previous 3 games combined would negatively affect all types of pitchers.

本文旨在探討身體活動測量的議題。首先，簡述客觀身體活動測量的背景，其次探究加速規在身體活動強度切點上的缺失，以及分析傳統的切點模式可能失準的原因等，最後提出加速規測量未來可能的發展方向如：類型辨識與類神經網路等。
