摘要: Comparisons of breast support requirements during overground and treadmill running have yet to be explored. The purpose this study was investigate 3D displacement comfort running. Six female D cup participants had retro-reflective markers placed on the nipples, anterior superior iliac spines clavicles. Five ProReflex infrared cameras (100 Hz) measured marker in four conditions. For running, completed 5 trials (3.1 m/s ± 0.1 m/s) over a 10 m indoor runway; for speed steadily increased 3.1 gait cycles were analyzed. Subjective feedback discomfort collected using visual analog scale. Running modality no significant effect (p > .05). Moderate correlations (r = .45 .68, p < .05) found between displacement. Stride length (m) frequency (Hz) did not differ conditions or modalities. Findings suggest that motion studies examine are applicable
