on both performance times and parameters in swimming. Subjects were 10 male coll egiate Swimmers. Here are their times in seconds to swin 200 meters at 90% of race pace when breathing every second stroke in front crawl swimming. 151.8 165 3 159.6 163.9 174.8 173.2 178 4 174.3 164.5 171. Calculate the mean of the data. (Enter your answer to two decimal places)
The respiratory system can be a limiting factor in maximal exercise performance. Researchers studied the effect of two breathing frequencies on both performance times and several physiological parameters in swimming. Subjects were 10 male collegiate swimmers. Here are their times in seconds to swim 200 meters at 90% of race pace when breathing every second stroke in front crawl swimming. 151.6 165.5 159.4 164.3 175.2 173.4 178.2 174.5 164.1 171.4 Calculate the mean of the data. (Enter your answer to...
Researchers from the United Kingdom studied the effect of two breathing frequencies on performance times and on several physiological parameters in front crawl swimming. The breathing frequencies were one breath every second stroke ( B2) and one breath every fourth stroke ( B4). Subjects were 8 male collegiate swimmers. Each subject swam 200 meters using each breathing frequency: once with breathing frequency B2 and once on a different day with breathing frequency B4. A paper states that the results are...
