还是句子分析

Volunteers who listened to Vivaldi's "Four Seasons" while working out on a treadmill did much better on a test of verbal ability than when they exercised without music, a team at Ohio State University found.
这句子too长啦！呵，晕了，帮我分析句子结构，另外后面than在句子中做什么成分？这是两个句子用连词than连接起来的，还是整个是一个句子，than连接的两个词又什么呢？
对各位大侠的回答表示真诚的感谢！

Volunteers who listened to Vivaldi's "Four Seasons"while working out on a treadmill 主语部分（定语从句，while working out on a treadmill --while+分词形式作状语）than以后部分作整个句子的状语，better...than...结构。自愿者们听到维瓦尔第的“四季”协奏曲时工作比他们在没有音乐时工作要好得多。俄亥俄州立大学队发现这一点。

Volunteers是主语，who listened to Vivaldi's "Four Seasons" 是定语（从句）
while working out on a treadmill 是状语
did much better 是谓语
than只是一个连词，比较级用。这是一个用than连接起来的整个句子
than连接的是句子和词组：a test of verbal ability和when they exercised without music
