Resumo
The markers of external training load (ETL), distance and intensity, do not take into
account the athletes’ psychophysiological stress, i.e., internal training load (ITL).
Thus, the aim of this study was to evaluate the relationship between ETL and ITL
using the rating of perceived exertion (RPE) and session-RPE in swimmers. Seventeen
young swimmers (10 male, 15.8 0.87 yr and 7 female, 15.1 0.46 yr) belonging to
one national level youth team took part in this study over 4 wk. The external training load was planned using swimming distance (in meters) at seven different training
intensities. Swimmers’ RPE was assessed 30 min after each training session.
Session-RPE was calculated by multiplying RPE by session duration (min). The relationship
between the variables was analyzed with Pearson correlations and a multiple
linear regression was performed to predict the session-RPE as a function of the
independent variables (aerobic and anaerobic volume). The swimming distance at
different intensities correlated strongly with RPE and very largely with session-RPE
(.64, p<.05 and .71, p<.05, respectively). Regression analysis indicated that the
aerobic and anaerobic volumes together explained more than 50% of the ITL variability.
In conclusion, the swimming distance in each training session was significantly
associated with RPE and session-RPE in swimmers. In other words, based on these
results, the use of high-volume training at lower intensities affects the RPE and
Session-RPE more than the anaerobic volume.
