BACKGROUND: In swimming one of the most employed training speed among coaches is the non-invasive Theoretical Critical Velocity (TCV) defined as the velocity that can be maintained continuously without exhaustion.
METHODS: We calculated the 4mmol/L lactate Critical Velocity (MCV) in a group of swimmers of different ages (Young, Elite and Master), and compared results to the predicted TCV defined starting from the 200 and 400 m freestyle best seasonal performances. A steady-state test consisted in 20 repetitions of 100 m each was performed to study the effect of the imposed MCV in the three athletes’ categories.
RESULTS: TCV mean values resulted slightly higher than MCV mean values. A strong correlation between TCV and MCV was found considering the whole sample (r= 0.96, p < 0.001), the Masters (r= 0.97, p < 0.001) and the Elite (r= 0.93, p < 0.01). Lactate concentration of the three groups after the steady-state test was 4.2 mmol/l, 3.3 mmol/l and 4.9 mmol/l respectively for Young, Elite and Master groups.
CONCLUSIONS: TCV is a reliable, practical and quick parameter that well approximate the anaerobic threshold pace. MCV underestimated the fixed 4mmol/L lactate threshold pace in the elite swimmers and overestimate it in the master swimmers. Further investigation is needed to understand more in detail TCV applicability for athletes of different ages.
