Databases can find much when two concepts are combined with the boolean
"and", especially in combinations where the two concepts are highly
correlated. As one moves to three concepts the databases start to get
irritated and when one moves to four concepts, the databases usually start
to go into a high state of rebellion. Now combining teachers and students
and classroom and lessons may yield a high number of citations as these
concepts are all heavily related to each other. When one gets to a
concept like snorkel and one like snorkels, one has a very small group of
records holding up that fort, so combining it with three other concepts
simultaneously is a very tall order indeed. The population for snorkel
combined with swimming is indeed quite small and here are some citations
that may be probative for your research from that small pool.
Respiratory snorkel and valve system for breath-by-breath gas
analysis in swimming.
By: Keskinen, Kari L.; Rodrguez, Ferran A.; Keskinen, Ossi P..
Scandinavian Journal of Medicine & Science in Sports
October 2003 Vol. 13 Issue 5 p. 322
Ventilatory and Metabolic Response to Rebreathing the Expired
Air in the Snorkel.
By: A. S. Toklu.
International Journal of Sports Medicine
April 2003 Vol. 24 Issue 3 p. 162
Snorkel training: practicing drills by using a front-end snorkel can
help enhance body balance and hip/hand timing.
Bottom, M.
Swimming technique (Sedona, Ariz.)
July/September 2001 Vol. 38 no. 2 p. 17-18
I hope that these citations prove to be of some help to you.
