Responders, Non-Responders, and Fish Oil (Episode 61)
Key Moments
Fish oil helps recovery, but not muscle growth. Responders/non-responders aren't reliable. Baseball is exciting.
Key Insights
Fish oil supplementation shows evidence of aiding recovery from exercise and improving muscle function restoration, but not muscle hypertrophy or strength.
The concept of classifying individuals as high, moderate, or low responders to training lacks reliability for high-intensity interval training and potentially other exercise modalities.
Recent feats of strength include Tom Stoltman winning World's Strongest Man, Ryan Crouser breaking the shot put world record, and Taylor Atwood setting new powerlifting totals.
There's a growing emphasis on the statistical and methodological rigor in psychological research, with critiques of popular concepts like the Dunning-Kruger effect.
Baseball has become significantly more interesting due to exceptional performances from Shohei Ohtani and Jake deGrom, and the prevalence of sticky substances used by pitchers.
Regular high-dose use of NSAIDs, high-dose vitamin C/E, and potentially high-dose antihistamines may blunt training adaptations in healthy young individuals.
UPDATES ON PERSONAL PROGRESS AND NEW SEGMENTS
The 'Good News' segment of the podcast has been suspended due to a perceived shift towards neutral or negative news. It will be replaced by Greg's 'Road to the Stage' segment, where he provides updates on his weight loss journey. Greg highlights a personal win in maintaining a caloric deficit despite less-than-ideal dietary circumstances, focusing on consistent small progress over drastic changes. Eric introduces his own 'Road to Enlightenment' journey into secular Buddhism, which has led him to adopt a meat-free diet and simplify his culinary practices, suspending his usual elaborate recipe content.
ATHLETIC FEATS AND RECORD-BREAKING PERFORMANCES
Recent feats of strength include Tom Stoltman's first World's Strongest Man title, narrowly defeating Brian Shaw. In track and field, Ryan Crouser shattered the shot put world record, previously held since 1991, by a significant margin. Powerlifting saw remarkable performances, notably Taylor Atwood breaking his own world record total in the 74kg class, achieving the first 600+ Wilkes total in drug-tested competition. Heather Connor also set a new record in her weight class. Impressive lifts from Bryce Lewis and Jamar Royster, along with Jimmy Kolb's record-equipped bench press, were also highlighted.
THE COMPLEXITY OF FISH OIL SUPPLEMENTATION
The podcast delves into the effectiveness of fish oil (omega-3 polyunsaturated fatty acids), particularly EPA and DHA. A systematic review indicates that fish oil does not significantly improve muscle hypertrophy or strength. However, it does show evidence for enhancing recovery, reducing delayed onset muscle soreness (DOMS), and improving muscle function restoration after exercise. The discussion touches upon the distinct roles of EPA and DHA, and how dose recommendations for general health (0.3-0.5g combined) differ from those studied for recovery (1-6g combined).
CHALLENGES IN IDENTIFYING TRAINING RESPONDER RELIABILITY
Research on classifying individuals as high, moderate, or low responders to training presents significant challenges. A study analyzing high-intensity interval training (HIIT) found that adaptations like VO2 max and time to task failure were not reliable across repeated exposures to the same training protocol, even after a three-month washout period. This suggests that individual responses may not be consistent, questioning the validity of defining 'responders' and 'non-responders' and potentially explaining the inconsistent predictors found in previous studies across various training types.
IMPACT OF PHARMACEUTICALS AND SUPPLEMENTS ON ADAPTATIONS
The discussion addresses whether athletes should avoid certain substances to optimize training adaptations. High-dose non-steroidal anti-inflammatory drugs (NSAIDs), high-dose vitamin C and E, and potentially high-dose antihistamines may blunt training adaptations in young, healthy individuals by interfering with the inflammatory and oxidative stress processes involved in muscle remodeling. In contrast, fish oil at typical doses is unlikely to negatively impact adaptations and may offer mild recovery benefits. However, for older adults or those with elevated baseline inflammation, these recommendations may not apply, and such interventions could even be neutral or beneficial.
DIETARY STRATEGIES AND PROTEIN DISTRIBUTION
The podcast explores the 'one meal a day' (OMAD) diet, concluding it's not ideal for protein distribution to support muscle protein synthesis throughout the day, though not entirely detrimental. The optimal strategy appears to be consuming 0.25-0.3g of protein per kilogram of body weight across at least three to six meals daily. Including a protein serving before bed is viable, provided it doesn't disrupt sleep. There's a cautionary note about excessive branched-chain amino acids (BCAAs) or rapidly digesting proteins before sleep potentially interfering with sleep quality due to competition with tryptophan transport.
PROGRAMMING FOR OLDER ADULTS AND DELVING INTO PSYCHOLOGY
For training older adults (60+), a program combining bodyweight and machine exercises is recommended. Machines offer low stability requirements for targeted muscle work, while bodyweight exercises are crucial for improving balance, kinesthetic awareness, and mitigating fall risks, especially for quad and calf strength. The discussion also critiques the popular interpretation of the Dunning-Kruger effect, noting that the original research showed less extreme overconfidence in low-competence individuals than commonly portrayed. The segment references critiques of popular psychological concepts lacking replication, highlighting a trend towards greater rigor in the field.
BASEBALL'S RESURGENCE AND CONTROVERSIES
Baseball is currently experiencing a surge in interest, notably through the unprecedented dual-threat capabilities of Shohei Ohtani, who excels as both a pitcher and hitter. Jake deGrom is also having an historically dominant pitching season with a remarkably low ERA. The sport's increased excitement is paralleled by controversies surrounding pitchers using sticky substances, like Spider Tack, to enhance spin rates and pitch movement, leading to historically low batting averages. This arms race in pitching technology and performance, coupled with individual brilliance, has revitalized the sport, even leading to discussions about potential MVP awards for pitchers.
