If a fish stopped swimming, changed direction, or swam beyond one body length from a model, the schooling bout was ended.
Although a thorough assessment of limb kinematics was beyond the scope of this study, previous work has demonstrated that both limb movement patterning and coordination involved in swimming change during early postnatal development [49], [50].
Changes in motility were observed in all groups: the percentage of total motile and progressive motile spermatozoa increased during passage through the epididymis, with major changes between the caput and corpus epididymides, and the pattern of swimming changed clearly towards more rapid and straighter trajectories.
When you're ready to swim, change out of your clothes and into your bathing suit, but don't put a pad on.
Associations between exposure to THMs measured in exhaled breath after swimming and changes in markers of genotoxicity before and after swimming were evaluated using linear regression.
Hence, it follows that because stroke rate is not a good predictor of swimming speed, changes in the thrust produced per stroke must explain the variation in swimming speed at speeds greater than 0.25 m/s because thrust balances drag and drag increases with speed.
The video movie of this sequence (Additional file 3) also shows several immotile cells, and demonstrates how the distribution of swimming behaviors changes moment to moment, preventing us from making quantitative statements about the relative abundance of various sperm swimming behaviors.
In 1986, Sindy manufacturers took advantage of new colour-changing technology and released Magic Moments Sindy, a doll whose hair and swimming costume changed colour when immersed in warm water.
"I think swimming has changed a lot since 2000," said Cesar Cielo Filho, a Brazilian who trains at Auburn who won the 50 and 100 freestyles.
There is some compulsion, some glint of mischievousness on the fresh Lanarkshire air, that is making people go to the swimming pool, change carefully into their trunks or costumes, totter into the blood-warm water and shit.
