Dr. Mike Zourdos, an expert in concurrent training and high-volume training, discusses topics such as the interference effect, extra-high protein intake, limitations of rodent research, and behavior change models in this episode of MASS Office Hours.
Higher volumes of training may lead to greater muscle growth, but individual response rates and downstream effects should be considered.
When progressing set numbers and RPE within a mesocycle, it's crucial to balance effective progress with avoiding excessive fatigue or burnout.
Understanding the nuances of rodent research is important for accurately interpreting and generalizing findings.
Deep dives
Effects of Different Weekly Set Progressions on Muscular Adaptations
This podcast episode discusses a study on the effects of different weekly set progressions on muscular adaptations in trained males. The study examined the impact of different set volumes (22, 42, and 52 sets per week for quads) on muscle growth. While the study did not find statistically significant differences between groups, there was some evidence suggesting that higher volumes may lead to greater quad growth. However, it is important to consider the individual rate of response and the downstream effects of such high set volumes. The study should not be seen as a definitive recommendation for extremely high volume training, but rather as an indication that volume cycling and individualized approaches may be beneficial.
Progressing Set Number and RPE within a Mesocycle
When it comes to progressing set number and RPE within a mesocycle, it is important to consider the balance between making effective progress and avoiding excessive fatigue or burnout. One approach could be to focus on proximity to failure, gradually decreasing reps or increasing load to bring sets closer to failure as the mesocycle progresses. However, it is vital to assess individual responses and adjust progression based on both performance and recovery. Additionally, it may be more feasible and effective to focus on progressing one or two key exercises each mesocycle rather than attempting to increase sets and RPE across all exercises.
Importance of Understanding Rodent Research in Relation to Generalizability
Understanding the nuances and specific characteristics of rodent research is crucial for accurate interpretation and generalizability of findings. Factors such as genetic lines, laboratory setting, and modified light-dark cycles can impact the relevance of rodent studies to human outcomes. Attention to these details is necessary for a comprehensive understanding of the research.
Behavior Change and Removing Barriers to Health-related Behaviors
Examining the psychological and behavioral aspects of exercise is essential for promoting behavior change. Understanding the barriers and interventions to overcome them is critical for increasing adherence to exercise and health-related behaviors. Implementing effective behavior change theories and interventions can lead to sustainable and long-lasting changes in individuals.
Appreciating the Importance of Funnel Plots in Meta-analysis
Funnel plots play a crucial role in meta-analyses by providing insight into the precision and bias of effect estimates. Understanding the magnitude of effect, along with the precision of the estimate, allows for better interpretation and decision-making. Embracing funnel plots when examining meta-analyses can enhance the understanding of the strength and credibility of research findings.
In episode #7 of MASS Office Hours, Dr. Eric Trexler is joined by Dr. Mike Zourdos. They discuss concurrent training, proximity to failure, extremely high training volumes, extra-high protein intake, limitations of rodent research, the importance of behavior change models, and much more.
