dc.description.abstractTraditionally, during cycling different pacing strategies are enforced for different length time trials. These pacing strategies require different physiological responses from the performers. The aim of this study is to observe these physiological responses during two 4-km time trials using self paced and flat power as the two strategies. With % VO2 attainment also being compared to VO2max. Seven male highly trained cyclists (age 20 (1.7) years, height 182.8 (5.33) cm, body mass 70.4 (4.19) kg) volunteered to complete the study. The participants took part in an incremental cycling VO2max test and a self and flat paced 4-km time trial. During all three tests VO2 was measured constantly using a gas analyser. Heart rate and VE (ventilation rate) were also measured using 30 second averages reporting the maximum values. These physiological variables were compared in each of the time trials. With VO2 in the two time trials compared to the VO2 reported in the initial incremental VO2max test. For the 7 participants the initial VO2max values 72 (4.9) ml•kg/min-1 with % VO2 during the self paced time trial being 100% and flat paced 101%. VE for the initial VO2max was 209 (25.2) l/min with % attainment during the self paced time trial 92 and 85 for the flat paced. With heart rate for initial VO2max test 195 (8.4) with % attainment for self 95 and flat 95. The results found no significant difference in physiological responses in the two time trials with p= >0.05. There was no significant difference between VO2max and % VO2 attainment during the two time trials with p= >0.05. The results show that there is no difference in physiological responses to different pacing strategies with VO2 during these time trials being elicited to VO2max levels.
