In this podcast, they discuss various interesting topics including restructuring medical school curriculum, cardiometabolic effects of vegan vs. omnivorous diets, proximity to failure in resistance training, comparing training intensities and volumes, challenges of researching exercise modalities, and stress urinary incontinence in female athletes.
A healthy vegan diet can lead to improved cardiometabolic outcomes compared to a healthy omnivorous diet.
Training close to failure is not necessarily superior for strength gains as long as intensity and volume are sufficient.
Heavy weight lifting can lead to stress urinary incontinence in some strength-trained women, emphasizing the importance of pelvic floor muscle training and addressing this issue among athletes.

Cardiometabolic effects of vegan vs omnivorous diets in twins
A study compared the cardiometabolic effects of vegan and omnivorous diets in 44 identical twins. The vegan group consumed fewer calories, less protein and fat, and more carbohydrates than the omnivorous group. The vegan group lost more weight and experienced a greater decrease in low-density lipoprotein cholesterol (LDL-C) levels compared to the omnivorous group. Other blood test results, such as high-density lipoprotein cholesterol, triglycerides, B12, and fasting glucose, showed no significant differences between the two groups. The study suggests that a healthy vegan diet can lead to improved cardiometabolic outcomes compared to a healthy omnivorous diet.
Effects of proximity to failure on strength adaptations
A study investigated the effects of proximity to failure on strength adaptations in trained men. The research found that when repetition and set volume were equated, muscle strength outcomes were similar for sets performed with 4-6 repetitions left in reserve and 1-3 repetitions left in reserve. Both approaches were slightly more effective than training sets performed to momentary failure (RPE 7-9+ and RPE 10). These findings support the notion that training close to failure is not necessarily superior for strength gains, as long as the intensity and volume are sufficient.
Acute effect of heavy weight lifting on pelvic floor muscles
A study explored the acute effect of heavy weight lifting on pelvic floor muscles in strength-trained women. The research focused on stress urinary incontinence, which is the involuntary leakage of urine during activities that increase intra-abdominal pressure, such as heavy lifting. The study found that heavy weight lifting can lead to stress urinary incontinence in some strength-trained women. This highlights the importance of pelvic floor muscle training and addressing this issue among athletes, particularly those involved in heavy lifting activities.
The Effect of Resistance Training Proximity to Failure on Muscular Adaptations
This podcast episode discusses a study on the effects of resistance training proximity to failure on muscular adaptations and fatigue in trained men. The study examined the concept of proximity to failure, which relates to the intensity of a workout. The findings suggest that training closer to failure may lead to more muscular damage and reduced performance potential. However, there is a counter argument that higher training stress, such as taking sets to failure, produces more fitness adaptation. The study found that training with a proximity to failure of 4-6 RPE or 7-9 RPE resulted in significant improvements in muscular strength, while training to failure (RP 10) did not produce significant strength gains. No significant changes in muscular hypertrophy were observed.
The Immediate Effects of Heavy Lifting on the Pelvic Floor in Women
In this podcast episode, a study on the immediate effects of heavy lifting on the pelvic floor in women is discussed. The study aimed to assess the resting pressure, strength, endurance, and activity of the pelvic floor muscles before and after squatting and deadlifting at 75-85% of one rep max. The results showed no significant differences in pelvic floor muscle resting activity, resting pressure, strength, or endurance after lifting or resting. There was also no correlation between general strength in exercises like the squat and deadlift and pelvic floor muscle strength. These findings suggest that heavy lifting does not have immediate adverse effects on pelvic floor muscle function in women.
