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 2 Comments

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

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 2 Comments

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, …

Swimmer’s Ankle Mobility Touch Your Toes to the Ground in 90 Days

Swimmer’s Ankle Mobility: Touch Your Toes to the Ground in 90 Days

admin Allan Phillips, Biomechanics, Blog, Dryland, Latest&Greatest Leave a Comment

Ankle mobility and flexibility is one of the holy grails of swimming body contortions. For some, it comes easy, while for others, it is more work. Fortunately, we’re here to offer a systematic approach as most tend to address it in a scattershot manner. To start, we’ll steal from other disciplines such as dance, whose culture is seen to be …

Take Home Message: 1. The aim was to perform the analysis of the final time improvement at different swimming turns push-off intensities and glide depths of a former world-ranked swimmer 2. The velocity would be 1.50, 2.18 and 3.02m/s performing the push-off 0.75m deep at 1.1, 1.5 and 2BW, respectively 3. For this swimmer, the optimal depth would be between …

Building The Perfect Swim Streamline Plus 7 Must Do Things

Building The Perfect Swim Streamline Plus 7 Must Do Things!

admin Allan Phillips, Biomechanics, Blog, Latest&Greatest 1 Comment

The swim streamline is a simple, yet often overlooked part of swimming at all levels. With the youngest swimmers, a good streamline is a foundation for teaching more advanced skills in body position and proprioception in the water. As the swimmer advances, the streamline becomes a critical fundamental factor competitively. Many swimmers and coaches skip the first and most important …

Swimming Computational Fluid Dynamics

Swimming Computational Fluid Dynamics

admin Biomechanics, Blog, Latest&Greatest Leave a Comment

Introduction The biomechanics and fluid mechanics of swimming concern itself with the complex nature of human interactions with and movement through a body of water in unsteady conditions. The evaluation and study of the motions of unsteady water in front of and behind the swimmers’ various body parts can elucidate many things about forward progression of a swimmer [5]. Investigations …

speed of breathing predicts 100 m performance

Speed of Breathing Predicts 100-m Performance

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

Take Home Points on Speed of Breathing Predicts 100-m Performance The faster a national caliber swimmer can exhale air in 1 second is correlated with 100-m performance. Everyone is trying to predict athletic performance in youth athletes. Not unlike other sports, swimming research has looked at many attributes of youth swimmers, including height, strength, and lean body mass. Dr. Barbosa has …

Drag in Swimming: The Good and The Bad

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

The Background Information: Drag in Swimming Have you ever wondered if there were small changes you could make in your stroke to improve performance? Or how finger, thumb or elbow position help change propulsion and drag in swimming? If you have, then a recent research article titled, “Effective Propulsion in Swimming: Grasping the Hydrodynamics of Hand and Arm Movements,” will …
