Abstract
This investigation examined the cross- training effect of swim training on middle distance running performance. Eight, healthy, untrained subjects (mean age + SD = 24.63 + 2.77 yrs) participated in a 12 week. swim training program. Before and immediately following the training period, measurements were made of: maximal oxygen consumption (V03 max.) (treadmill); anaerobic capacity (Wingate test); knee and shoulder muscle strength (isokinetic dynamometer); 100m and 200m swim time- trials; and 400m and 800m run time-trials.
VO- max. increased from a mean of 42.06 + 5.1 ml/kg/min. to 45.39 + 5.05 ml/kg/min. (8.137. ; p< 0.005). The 100m, 200m swim times and the 400m, 800m run times improved significantly in response to the swimming training (p< 0.0001).
Dynamometry
showed significant
inc reases
in power and
work
during knee
flexion at an angular velocity
of
60 °/sec;
knee
extension at
245 °/sec; and
during shoulder
f1 ex ion
and
extension at
195 and 245 °/sec.
The Wingate
test
however,
did
not show any changes after the training period.
A cross-training effect by swim training on running performance was attained among the untrained, non- competitive swimmers of this study. While mode of activity was non- specific, a training response was attained by keeping the intensity and volume of the swim training specific to middle
distance run training.
