Resistance Exercise Load Does Not Determine Muscle Size

Resistance Exercise Load Does Not Determine Muscle Size

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

It is commonly thought the more weight one lifts during resistance training, the greater increase in muscle size (hypertrophy) occurs. Unfortunately, there is minimal evidence suggesting these two conditions correlate. Moreover, the size of a muscle is not suggested to correlate with swimming success. Instead of a percent of maximum, the total volume of weight lifted is potentially a means …

Comparing Sprint and Strength Training Methods

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

Resistance training is a common mode in dry-land to enhance out of water strength. Despite the lack of correlation between out of water strength and in water strength, many programs have found anecdotal success with resistance training. This is likely due to poor methods correlating in water strength and poor resistance training programs. Moreover, most studies comparing resistance training have …

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 …

Take Home Points on How to Prevent Swimming Burnout Physiological capacities are limited after maturation. Technique is the largest contributor of success, especially after maturation. Burnout is higher in women, potentially due to earlier development and longer period of plateauing.  Improvements in swimming naturally occur during maturation, in fact, one can expect 3 – 4% improvement during these years (Sweetenham 2013). …

Background on Intensive Training and the Innate Immune System  Exercise is good for health. However, elite athletes seem to be prone to illness during periods of heavy training. Elite athletes are not immune deficient, but intensive training could lead to immune system depression. Most athletes self-report being sick with upper respiratory systems (RPS). However, these symptoms are not always confirmed …
