Future of Swimming Training

Dr. GJohn Mullen Blog, Competition, Latest&Greatest, Training 1 Comment

Smart technology is on the verge of dramatically enhancing swimming performance, be ready for the revolution. Swimming is one of the most biomechanically difficult sports. Unlike other sports, swimming works against water while in a horizontal position. The unfamiliar horizontal position makes all stroke corrections more difficult. Water also creates resistance during any motion, making improvements harder! This motion creates …

Effects of Barbell Deadlift Training on Submaximal Motor Unit Recruitment for the Quadriceps

Effects of Barbell Deadlift Training on Submaximal Motor Unit Recruitment for the Quadriceps

Dr. GJohn Mullen Biomechanics, Blog, Competition, Dryland, Training 5 Comments

Background on the Barbell Deadlift Dryland Training has become a quintessential aspect of swimming. Not only does dryland provide the opportunity for athletes to become stronger but it also provides an avenue for the body to create improved physiological adaptations resulting in more functional strength and faster times in the water.   The barbell deadlift is an exercise that requires …

Low Intensity Exercise under Hypoxia: Hormonal Effects

Low Intensity Exercise under Hypoxia: Hormonal Effects

Dr. GJohn Mullen Blog, Competition, Training Leave a Comment

Blood flow resistance training has been suggested to improve muscle strength and size at lower loads due to similar hormonal releases compared to resistance training. This acute hypoxia has stemmed research on systemic hypoxia. Training in systemic hypoxic conditions is also suggested to improve growth hormone (GH) release. However, the effects of systemic hypoxic conditions have yet to be determined. …

Finger and Toe Spreading Efficiency

Finger and Toe Spreading Efficiency

Dr. GJohn Mullen Blog, Competition, Training 2 Comments

The position of the fingers and toes is seldom discussed on pool decks. Literature suggests a slight spread of the fingers maximizes propulsion. Moreover, the amount of spread is proportional to the speed of the moving object. However, there is a debate if a larger paddle exerts more force on the surrounding water, leading to less efficient swimming. This study …

Using Rhythm (Music) to Improve Recovery

Using Rhythm (Music) to Improve Recovery

Dr. GJohn Mullen Blog, Competition, Psychology, Training Leave a Comment

Music is utilized in many sports for motivation. In swimming, underwater music players have increased in commonality and popularity. Studies have found positive correlations between music and improvements on sub-maximal aerobic performance. However, conflicting results exist in music and supra-maximal exercise. Even if beneficial, listening to music is not allowed in competition. However, using music during recovery is allowed and …

Freestyle Deep Catch/High Elbow Catch Thrust Comparison

Freestyle Deep Catch/High Elbow Catch Thrust Comparison

Dr. GJohn Mullen Blog, Competition, Training Leave a Comment

Much debate surrounds the ‘ideal’ catch in freestyle. Many suggest a high-elbow catch theoretically maximizing propulsion (‘drag-based’), while others believe in a low-elbow or ‘S-curve’ catch to maximize mythical lift (‘lift-based). Unfortunately, the lift has only been theoretically determined in swimming, subjecting it to much scrutiny in the sport. In the current study, the researchers used computational fluid dynamic modeling …

No matter the distance, every swimmer is out of breath at the end of a race….excuse me if I just blew your mind!  This obvious statement has lead swim coaches to attempt various training means to prevent “being out of breath” as the main limiting factor in swimming.  The most common attempt was increasing swimming volume, while others implemented underwater …
