Anaerobic contribution can quickly decrease, even in shorter time line events (20-30 sec, 200m running, 50m swimming). Previous
authors have demonstrated aerobic contributions between 29 and 40% for various levels of athlete over this time course in a range of exercise
types (Running, cycling swimming rowing). We have developed methods that demonstrate better clarification of systemic use and wished to
understand these differences during competition conditions. 440 subjects (299 Male & 141 Female) volunteered to take part in this study and
were drawn from a number of national events. Blood lactate and glucose were tested immediately post swim until a peak of each parameter
was found. Swim time and stroke parameters were also collected for each swim. Data were collected in all event distances (50m 100m 200m
400m 800m & 1500m).
The generation of system contribution followed the methods of Swanwick & Matthews (2018). The comparison of contribution in male
Freestyle events, 50m-100, showed significant differences in glycolytic and anaerobic contributions (P≤ 0.0002), 100-200, anaerobic only
(P≤ 0.0002) and 400 to 1500m in aerobic and anaerobic (P≤ 0.0002) Females showed less differences in system contributions (50-100,
glycolytic, (P≤ 0.01) and 200-400m (anaerobic, P≤ 0.002). When glycolytic and anaerobic capacities were combined, our results were in
agreement with Conclusion; The model has demonstrated values that are in line with previous authors but has greatly increased the possibility
of understanding energy contribution differences through the identification of the importance of the glycolytic contribution during vigorous
and maximal exercise.
