Traditional boards of lumber were fairly strong against forces parallel to the wood's fiber growth.

传统的木板能够坚守对抗与木材纤维生长方向平行的力量。

Conversely, the high-load group had a slightly greater type 2 fiber growth (15 vs 12) .

相反，高负荷组的2型纤维增长略快，达到15% 而1型只有12％。

The next crucial stage of the cotton fiber's growth begins as it thickens its secondary cell wall by depositing large quantities of cellulose into the secondary layer.

在下一个棉花纤维成长的关键阶段，大量纤维素在次生细胞壁内堆积并从而强化细胞壁。

In a 2012 study, when comparing 80% 1rm to 30% 1RM training, the light group increased type 1 fiber growth by 23% versus 16% in the high load group.

在一份2012年的研究中，研究者比较了80%的 1RM 和30%的 1RM 训练，低负荷组1型纤维增长了23%，而高负荷组增长了16%。
