Below is an interview on the principle differences and movements between weightlifters and powerlifters.  Whats included and demand in each sport.  Here is the latest article to Lars Berglund’s “Injuries Among Weightlifters and Powerlifters: A Systematic Review”  his latest studies and complete research work sites can be found here. 1. First off, what is the difference between weightlifters and powerlifters? The principal differences …

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 …

How to Swim the Breaststroke

How to Swim the Breaststroke

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

Take Home Points on How to Swim the Breaststroke Body position should be sought between each stroke. The breaststroke breath should be low to minimally disrupt streamline. The kick should occur with the arms and head in streamline. While butterfly is commonly depicted as the hardest stroke, breaststroke is typically the most difficult to master. Even many elite swimmers do not …

When describing joint movement, a reference position is needed. This position is termed the anatomic reference position. This position entails: an erect standing position with the feet slightly separated, the arms hanging by the side, the elbows straight, and with the palms of the hands facing forward. Planes of Movement The following planes are described relative to the median plane, …

Does Fatigue Alter Swimming Shoulder Mechanics?

Erin Cameron Biomechanics, Blog, Dr. Erin Cameron, Latest&Greatest, Research Abstract 1 Comment

There are many factors that contribute to the high prevalence of swimming shoulder pain. High repetitions of overhead activity, muscle imbalances, range of motion deficits, poor posture, poor stroke mechanics (and many more) are all thought to play a role. A recent article published in the Journal of Bodywork and Movement Therapies investigated the effect of fatigue on swimming shoulder mechanics …

Ankle Swimming Flexibility

Ankle Swimming Flexibility

Dr. GJohn Mullen Allan Phillips, Biomechanics, Blog, Dryland, Latest&Greatest, Training Leave a Comment

Background on Ankle Swimming Flexibility Improving ankle mobility in freestyle, backstroke, and the butterfly is often vexing for both swimmers and coaches. Some swimmers appear naturally blessed with mobile ankles. Others work madly to force plantar flexion (toes pointed down) but make little progress. Although plantar flexion and dorsiflexion (toes pointed up) are both needed for dynamic ankle mobility in …

How is Middle Distance Swimming Related to Oxygen Uptake Kinetics?

How is Middle Distance Swimming Related to Oxygen Uptake Kinetics?

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

Background on VO2 (Oxygen Uptake) Kinetics  Middle distance swimming is a unique blend of anaerobic and aerobic exercise. This mix of moderate to high intensity requires coordination between the cardiorespiratory and muscular systems. It is believed the faster VO2 kinetics and reduced amplitude of the slow component are highly correlated with higher levels of aerobic fitness, improving fatigue tolerance. Unlike …

Undulation Technique to Improve Your Butterfly Stroke

Undulation Technique to Improve Your Butterfly Stroke

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

Background On The Butterfly Stroke If you want to practice the Butterfly stroke on a competitive level, you need to work on the movement which is its basis: the undulation technique. This technique is based on the movement of your body in the water. It requires much higher energy dispersal compared to other techniques. Let us look more closely at …

Analysis of the Freestyle Recovery Stroke on the Cartesian Plan

Analysis of the Freestyle Recovery Stroke on the Cartesian Plan

Dr. GJohn Mullen Biomechanics, Blog, Dr. John Mullen, Latest&Greatest 1 Comment

Background on the Freestyle Recovery Stroke Did you know it’s possible to adjust the distance between the elbow and the central point of the head? Simply take the elbow’s height into consideration (pic. 1 to 4). This will have an impact on the recovery of the overwater arm. In fact, the recovery of the arm over water depends on the …

Link between stroking parameters and lactate concentration in swimming

Link Between Stroking Parameters And Lactate Concentration In Swimming

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

Background On Stroking Parameters and Lactate Concentration Swimming is a unique sport where volumes much larger than the actual distance competed are used as training. Often times, this over distance training is used to improve “feel” for the water. Unfortunately, after long swims, swimming biomechanics are believed to become impaired. Moreover, many practices consist of repeated efforts of intermittent efforts, …
