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 6 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 …

Rotational Power Test

Rotational Power Test

Dr. GJohn Mullen Biomechanics, Blog, Competition, Training 1 Comment

Core muscular endurance is a variable associated with low back pain rehabilitation. Core training is believed to improve ground sports performance but has not been confirmed in swimming. Rotational power is deemed an important variable in rotational power athletes. The correlation between rotational power and swimming success has yet to be proven, but many dry-land programs strive for improved rotational …

VO2 Kinetics on Heavy Swimming

VO2 Kinetics on Heavy Swimming

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

The intensity of exercise prescribed during a workout is typically defined based on the pulmonary oxygen uptake and blood lactate response to constant work. This is easily researched in running and cycling but is difficult in swimming. Therefore, many coaches prescribe intensity based on experience. A slow component of the VO2 kinetics is superimposed upon the rapid response, resulting in …

Athletic Training Effects on Spinal Curvature

Athletic Training Effects on Spinal Curvature

Dr. GJohn Mullen Biomechanics, Blog, Injuries, Training Leave a Comment

Background on Spinal Curvature The excessive spinal curvature is common in the sport of swimming. This frequency is difficult to interpret as many health care professionals have recommended swimming as a sport for rehabilitation, yet many others have linked swimming as a cause of this excess curvature. Spinal curvature in the adolescent spine typically involves curves in the sagittal plane …

Is HIT (High Intensity Training) useful for swimmers? Part 2

Is HIT (High Intensity Training) useful for swimmers? Part 2

Dr. GJohn Mullen Biomechanics, Blog, Dryland, Training 2 Comments

The physiology behind High-Intensity Training (HIT) The scientific evidence in support of high-intensity training has increased the number and quality of studies, especially those involving high-level athletes. It’s already known that a large number of swimmers, all over the world, are applying the basic principles of this scientific methodology using a large number of different strategies (including ultra-short race-pace training (USRPT) and …

If you follow SwimSwam or Swimming World Magazine you’ve certainly noticed the great interest in ultra-short race pace training (USRPT) and elite age-group professional swimmer Michael Andrew. Posts on these topics receive massive traffic and great controversy regarding training and many other topics. As written previously, here are the differences between the various forms of training: HIT: High-intensity training (HIT) involves performing …

Swimming Kick Start Versus Grab Start: Which is Faster?

Erin Cameron Biomechanics, Blog, Competition, Dr. Erin Cameron, Latest&Greatest, Research Abstract Leave a Comment

When the back plate was approved by FINA in 2009 many studies were performed to determine the benefits of using the back plate for a “kick start” (KS) versus a standard track start (TS). The majority of these studies concluded that the KS was superior in take off velocity, block time, flight time and time to 5 m – 15 m. Fewer …

How to Analyze Breaststroke Swimming

How to Analyze Breaststroke Swimming

Dr. GJohn Mullen Biomechanics, Blog, Dr. Tiago Barbosa, Latest&Greatest Leave a Comment

As a take home message: 1. In this piece, we did the analysis of three age-group breaststrokers. 2. Modeled data sometimes does not fit completely the individual data of a specific swimmer. 3. After benchmarking the swimmers against data retrieved from the literature we have learned that one of the swimmers is able to reach a high speed (strong point), but with …
