The moderate volume group performed 3 sets, totaling 18 and 27 sets per muscle each week.

中量组重复3次，每周上下肢分别训18组和27组。

And the low volume group performed...just one single set per exercise, totaling only 6 and 9 sets per muscle each week.

而小量组则仅完成1次力竭训练就够了，每周上下肢肌群训练量仅为6组和9组。

On average, it took 68 minutes to complete a session for the high volume group, 40 minutes for the moderate volume group, and only 13 minutes for the low volume group.

平均来看，高量组每次训练要花费68分钟，中量组则要花费40分钟，而小量组则仅用13分钟。

In their 8-week experiment, 34 college-aged male subjects with at least 1 year of resistance training experience was split into three different workout volume groups: high-volume, moderate-volume, and low volume.
