Does Baking Soda Improve Swimming Performance?

Dr. GJohn Mullen Blog, Competition, Dr. John Mullen, Latest&Greatest, Nutrition/Supplements, Training 1 Comment

Background on Baking Soda Sodium bicarbonate or baking soda is a commonly used ergogenic aide with mixed literature ineffectiveness. The mechanism behind sodium bicarbonate is to buffer the acid hydrogen ions from high-intensity exercise and lactate accumulation. Most literature has investigated the effectiveness of acute loading, just prior to a high-intensity performance. However, chronic loading for 3-6 days prior to …

What is the Influence of Capsaicin (CAP) for Swimmers in Sprint Training?

What is the Influence of Capsaicin (CAP) for Swimmers in Sprint Training?

Dr. GJohn Mullen Blog, Dr. John Mullen, Latest&Greatest, Nutrition/Supplements, Training Leave a Comment

Background on CAP for Swimmers  The ability to perform repeated sprints with minimal fatigue is important for swimming training and competitions with multiple events with minimal rest. Supplements are an enormous industry, commonly projecting breakthrough supplements to improve performance. IL-6 is a cell signaler (cytokine) with both pro-inflammatory and anti-inflammatory effect, which may be important in the recovery process, but …

Where Should Blood Lactate Samples be Taken From in Swimmer's?

Where Should Blood Lactate Samples be Taken From in Swimmers?

Dr. GJohn Mullen Blog, Dr. John Mullen, Latest&Greatest, Training Leave a Comment

Practical Static and Dynamic Stretching for Swimmers

Dr. GJohn Mullen Blog, Latest&Greatest, Training Leave a Comment

Take Home Points on Practical Static and Dynamic Stretching for Swimmers Dynamic stretching positively influences countermovement jump performance. Static stretching longer than 90 seconds likely impairs performance. Conflicting research exists between the timing, magnitude, and duration of static or dynamic stretching and their effects on performance requiring explosive power and quick reaction time. Structuring a proper warm-up can optimize performance while an improper …
