Effect Of Variation Of Load On Swimmers Bla And Hr After Exercise

Introduction
It is confirmed that the variation of load lead to variation of energy metabolism in the training. The purpose of this study
is to explore swimmer’s reaction with different workload, which is important to improve the scientific design of load
and reasonable monitoring in training program.

Method
Review, experiment, statistic analysis were used.

Results
1There was significant difference among highest BLA with varied distance and varied load after the maximum intensity
of load, which reflected the characteristics of energy supply, respectively.
2 The appearance time of BLA is inversely proportional to the distance when loading. The BLA after loading in 400m
was removed faster and the BLA in 200 was removed the slowest.
3 There was significant difference in BLA fluctuation curve among three different distances: the curve of 400m and
200m showed double-peak graph and that of 100m showed single-peak one.
4 varied speed in BLA and HR didn’t show synchronized trend. It also showed that the reduction percentage of BLA is
3/5 of the HR’s at 5 minutes after loading.

Conclusions
1 BLA and HR showed different characteristics when varying distances and loads after loading,
which provided advices for coaches to monitor load intensity and design loading program.
2, BLA should be taken into consideration in interval training besides HR.
