TABLE 2.

Pearson correlation coefficients among physical activity scoring methods (N = 239).

	Peak Strain Scorea	Hip BLE Scoreb	Spine BLE Scorec
Total activity scored	0.595*	0.714*	0.729*
Peak strain score		0.706*	0.712*
Hip BLE score			0.963*

BLE, bone-loading exposure.

^aTotal peak strain score = Σ (strain scores for all leisure physical activities).

^bHip BLE score = Σ_{1 – n} (hip loading unit × number of seasons × frequency × years).

^cSpine BLE score = Σ_{1 – n} (spine loading unit × number of seasons × frequency × years).

^dTotal activity score = Σ_{1 – n} (frequency × intensity × load × duration).

^*P < 0.01.
