Abstract
AbstractThis study aimed (i) to analyze the 1500 m open water swimming performance, (ii)
to examine the associations between physiological and biomechanical variables
with swimming performance, and (iii) to determine which variables can predict
swimming performance in triathletes. Fourteen elite triathletes (23.4±3.8 y)
performed a 1500 m test in open water swimming conditions. Swimming performance
was assessed using World Aquatics Points Scoring, and data were obtained from
the 1500 m open water swimming test. Heart rate, end-exercise oxygen uptake
(EE˙VO2) and blood lactate concentrations were measured. The
initial 250 m of the 1500 m swimming test presented the highest values of
biomechanical variables in males (i. e. swimming speed, stroke rate (SR), length
(SL), index (SI)). A decrease in SL was observed in the last 250 m in both
sexes. Positive association were found between EE˙VO2 (r=0.513;
p=0.030), swimming speed (r=0.873; p<0.001) and SI
(r=0.704; p=0.002) with swimming performance. In contrast, time constant
of the oxygen uptake (r=−0.500; p=0.034) and buoy-turn times (r=−0.525;
p=0.027) were negatively associated with performance. SI was the main
predictor (R
2=0.495) of open water swimming performance in
triathletes. In conclusion, triathletes and coaches must conduct open water
training sessions to maximize SI (i. e. swimming efficiency).
