Maximum power output developed by upper limbs in swimming ergometer exercises, sustainable for at least 20 s, was studied in 156 junior swimmers aged 10 to 14 years. Moreover, the responses to two exercise tests were studied in 6 elite junior swimmers. The tests consisted of 3 bouts each of increasing intensities: moderate, at the anaerobic threshold, and a maximal one. One test was performed on swimming ergometer, the other in the swimming pool, and both tests were supposed to be comparable regarding the intensities of consecutive bouts. It could be concluded from the obtained results that the specialized training in swimming considerably improved the power potential of upper limbs, and further, that the exercises performed on a swimming ergometer resulted in the level of metabolism comparable to that resulting from exercises in the swimming pool despite to total time of the latter exercise being about twice longer than that of the former.
