There is an association between NRF-1 genotypes (rs2402970 and rs6949152 polymorphisms) and the baseline and/or training response of human aerobic capacity. More research is needed to corroborate our data in other ethnic groups with lower fitness levels at the pre-training state (particularly Caucasians) and to identify the molecular mechanisms involved in the genotype-phenotype associations we found.

In order to investigate the effect of exercise modality and bra type on vertical breast displacement, seven participants with similar ages and body types were selected to take part in this study. Three-dimensional motion capture system (NDI Optotrak Certus) was used to collect the data of vertical breast displacement when participants were walking at the speed of 5 km/h, jogging at the speed of 7.5 km/h, running at the speed of 10 km/h on a treadmill, and rope skipping at the frequency of twice per second. It was found that there was no significant difference in vertical breast displacement between rope skipping, jogging and running. And the vertical breast displacement when wearing sports bra is significantly less than everyday bra in four exercise modalities. The results of this study might be useful for designing special sports bra for rope skipping modality.
