*ID: The numbering scheme of these Child Playing pre-activity gravimetric loading identifiers corresponds to that of the Child Playing post-activity gravimetric loading identifiers: CPGPre## = Child Playing Gravimetric (data) Pre-activity No. ##.

**Soil Type: W = wet soil (15.6-18.1% moisture); D = dry soil (2.6-3.6% moisture). Given range is of mean values of three measurements taken at each trial.

*ID: The numbering scheme of these pre-activity gravimetric loading identifiers corresponds to that of the post-activity gravimetric loading identifiers: APWGPre## = Adult Pipe-layer Wet Soil Gravimetric (data) Pre-activity No. ##; APDGPre## = Adult Pipe-layer Dry Soil Gravimetric (data) Pre-activity No. ##.

**Soil Type: W = wet soil (17.0-17.9% moisture for adult transplanters and 9.0-11.9% moisture for adult pipe-layers); D = dry soil (5.2-7.0% moisture). Given range is of mean values of three measurements taken at each trial.

***Time: Time spent performing pipe-laying activity in soil bed.

Note: All adult pipe-layers wore short-sleeve shirts and short pants.
