Fatigue Mechanisms, HIIT Programming, and Sex Disparities in Research
The Stronger By Science Podcast
Poky Man Legends Arsius Review
Poke mon legends arcus still contains the cor pokimon d and a whole being a very welcome change of pace. The game is not like a fully open word old but it's kind of like a semi open world concept. Instead of just a poke on jumping out at you from the wild grass, uh, you can see them all there. You're actively trying to avoid pokimon who are trying to attack your character.
In today’s episode, Greg and Eric revisit the topic of buffering supplements and fatigue as Eric presents a Research Review about the mechanisms driving neuromuscular fatigue. After that, Greg discusses his cover story from the most recent issue of the MASS Research Review, which is also available at strongerbyscience.com. In the article, Greg explores under-representation of female participants within strength, hypertrophy, and supplement research. The discussion covers the extent of the disparity, the surprising observation that the gap is getting worse over time, and how this research imbalance impacts training and nutrition recommendations for female lifters. Next, Eric shares a Coach’s Corner segment about programming high-intensity interval training (HIIT) and sprint interval training (SIT) for lifters. Finally, to close out the show, Eric and Greg share some music and video game recommendations.
