Without bag (2·0±0·9°) was different from 1BP 17·6±1·8°) and ATH (15·6±2·1°). 1BP was also different from 2BP (3·4 ±1·1°). Bag carrying significantly decreased stride length (1·597plusmn;0·04 m) and increased stride frequency (57·36±1·6 cycles/min) compared to WO (1·72±0·06 m; 54·64±1·2 cycles/min, respectively), thereby reducing the support phase of the gait
