30 Seconds SummaryConcurrent Training for the Powerlifter, Part 2: Physiology & Application
- Concurrent training may produce greater muscle hypertrophy than resistance training alone in some contexts, challenging traditional views.
- Molecular signaling pathways, specifically the mTOR and AMPK/SIRT1 pathways, play critical roles in how endurance and resistance training interact, with potential interference in hypertrophy.
- Muscle fiber types affect molecular signaling; endurance training generally activates slow-twitch fibers while resistance training activates both slow and fast-twitch fibers.
- Muscle glycogen levels, crucial for energy during exercise, can affect training performance and adaptation, particularly in powerlifting where high-intensity training is common.
- Timing between endurance and resistance training sessions is crucial; short recovery times can lead to interference effects, whereas longer intervals (ideally 24 hours) are recommended to avoid performance decrements.
- Programming should consider these physiological insights to optimize concurrent training, ensuring enough recovery time between different training modalities and carefully planning the intensity and timing of each session.
