Neuromuscular Response to Pain and Exercise Induced Muscle Damage

Neuromuscular Response to Pain and Exercise Induced Muscle Damage

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

Muscle soreness and pain are common sensations following a bout of unfamiliar exercise. This is believed secondary to lengthening and damage of the muscle fibers resulting in inflammation. Moreover, this damage results in changes in neuromuscular function and force production. Surprisingly, this decrease in force is not seen until 12 hours following exercise, perhaps due to pain not occurring until …

Do I Have Core Strength?

Do I Have Core Swimming Strength?

Instability Training Improves Joint Proprioception

Dr. GJohn Mullen Blog, Dryland, Training 1 Comment

Background on Instability Training Although instability is often used to strengthen the core and hips, the translation of this to dynamic movement is not certain. Also, the influence of instability training on proprioception is also not well established. This study looked at the effects of instability training. What was done Forty-three participants were split into a training program for 10-weeks …

Core Stability Still Requires More Research for Performance Enhancement

Core Stability Still Requires More Research for Performance Enhancement

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

There is an inherit association between core stability and swimming performance. However, if swimming improves core stability, how does core stability improve swimming? In swimming, the core muscles recruited are task-specific and are unique to each task. Swimming skills are specific to the exact swimming skill and even the same stroke at different speed may not be specific. Transfer Many …
