Background and purpose: In an endurance sport such as triathlon, coaches at the elite level strive to select an appropriate nutritional strategy prior to performance in addition to optimizing the training process. Based on this, the research in question was designed with the aim to verify the effect of caffeine on the running performance of performance triathletes during the preparation period. Purpose is to determine the effect of caffeine on running performance in triathletes.
Material and methods: The study sample consisted of 8 performance triathletes from the TRIAN club of ŠK UMB Banská Bystrica, whose age was 16.7 ± 0.67 years. Diagnostics were run on InSPORTline Condi T6000i treadmill with the aim of detecting lactate and blood sugar levels (mmol/l) before the performance and within 10 seconds after the performance. The blood lactate level was detected with the portable device Lactate Scout+ and the blood glucose level was measured with the Wellion CALLA light glucose meter. The running pace at which the participants performed the test was at anaerobic threshold and they attempted to cover a distance of 1,500 m at a constant incline of 3%. The testing took place 1 time per week in the morning hours (08:00-08:30). On the second day after the initial testing from 01.03.2023 to 14.03.2023, the participants started taking placebo (magnesii lactas) on a daily basis in form of capsules. The participants took 2 capsules (200 mg magnesium) which they consumed with 200 mL of water 45 to 60 minutes before each morning workout/test. This was followed by the administration of caffeine capsules, which they consumed for an additional 2 weeks from 03.15.2023 to 03.28.2023. The participants consumed caffeine capsules at 5 mg/kg body weight 45 to 60 minutes before each morning workout/test. The intervention programme lasted 5 weeks.
Results: When administering caffeine capsules at a dose of 5 mg/kg body weight, there was a significant reduction of approximately 26% in the average blood lactate level of the participants after the 1,500 m run. The participants' mean blood glucose levels increased by approximately 4.9% after the 1500 m run.
Conclusions: Based on the results we can claim that for ergogenic effects on performance we recommend supplementing with 5mg/kg body weight of caffeine approximately 45 to 60 minutes before training.
