one class session's impact

[sky753]

Hello Everyone,

Why "session" is used in this sentence?

... the researchers investigated one class session's impact on eating meat ...

Does the author mean that the class lasts some 45 minutes or one hour or something like that? And the investigators studied the 1- hour (or 45 minutes ...) period?

Best Regards

sky
