SIT is as, or more, effective than moderate intensity continuous training (MICT) for systemic and metabolic adaptations of muscles, despite a lower workload and shorter duration. However, the mechanisms underlying the metabolic response to SIT versus MICT are poorly understood. Our recent work (Zanou et al. 2021) suggests that increased pyruvate dehydrogenase (PDH) activity may explain why a SIT session led to greater changes in proteins involved in mitochondrial respiration compared to a MICT session.\n\nRecently, it was found that a natural and commercially available compound based on olive leaf extract could stimulate resting mitochondrial bioenergetics by activating the mitochondrial calcium uniporter (MCU), which is involved in calcium transport across the mitochondrial membrane, directly controlling PDH activity. The main objective of this study is to determine the effectiveness of an acute nutritional intervention (olive leaf extract) combined with a specific training session (MICT or SIT) on PDH activation (as well as other protein expressions) and exercise-induced muscle fatigue.\n\nParticipants will be allocated to either a SIT (6 x 30 s all out sprints) or a MICT (1h at 50% maximal aerobic power) group and asked to come to the laboratory for five visits including one familiarization session with a triangular test for maximal aerobic power determination, the first experimental session during which they will realize the exercise with the product or a placebo and a session 24h after to assess skeletal muscle adaptations. Then after a 3 week wash-out period, they report to the laboratory for the fourth and fifth session, identical to the second and third sessions but with the other intervention (product or placebo). Muscle microbiopsies will be collected from the vastus lateralis muscle before, immediately after and 24 hours after exercise (MICT or SIT), while knee extensor neuromuscular function will be assessed at the same time points using voluntary and electrically-evoked contractions.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '40 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
