Efectos del ejercicio sobre la glucosa y el lactato en triatletas amateurs

Objective: In this study, we compared the glycaemia and lactate response during exercise and recovery in running and cycling in a group of amateur triathletes. Methods: In 2019, 59 male amateur triathletes (32.9±4.55 years) from the province of Barcelona were randomly assigned to a treadmill stress...

description Objective: In this study, we compared the glycaemia and lactate response during exercise and recovery in running and cycling in a group of amateur triathletes. Methods: In 2019, 59 male amateur triathletes (32.9±4.55 years) from the province of Barcelona were randomly assigned to a treadmill stress test (n=30) or a cycle ergometer test (n=29). Ventilatory parameters, glycaemia and lactate, were obtained before the test at rest, at the end of the test and after 5 minutes of recovery. Results: At the end of the test and during recovery, blood glucose was higher in the treadmill group than in the cycle ergometer group (p

Results: At the end of the test and during recovery, blood glucose was higher in the treadmill group than in the cycle ergometer group (p&lt;0.001). Lactate was higher in the cycle ergometer than in the treadmill at the end of the tests (p=0.039). Conclusions: The results of this study reveal significant metabolic differences between running and cycling during maximal effort tests. Blood glucose was higher at the end of the treadmill test and during recovery compared to the cycle ergometer. This suggests a greater release of glucose during running, possibly due to greater muscle recruitment and energy demand. In contrast, lactate levels were higher after the cycle ergometer test, which could be attributed to a more localized effort in specific muscle groups. Our findings should be taken into account by sport scientists and triathletes when designing their training programs to promote greater effectiveness in physical preparation and performance.</description><identifier>ISSN: 1579-1726</identifier><identifier>EISSN: 1988-2041</identifier><identifier>DOI: 10.47197/retos.v62.106123</identifier><language>eng ; spa</language><publisher>Madrid: Federación Española de Docentes de Educación Física (FEADEF)</publisher><subject>Amateurs ; Cardiac stress tests ; Fitness equipment ; Glucose ; Running ; Triathlon</subject><ispartof>Retos (Madrid), 2025-01, Vol.62, p.807</ispartof><rights>2025.
