Though many feel core strength is essential for athletes, measuring this strength is not well understood. This study attempted to analyze the impact of dynamic core strength on performance and find a measurable field test. What was done Twenty-five Division I collegiate football (~19.0 years) players performed medicine ball throws (forward, reverse, right, and left) in static and dynamic positions. …

Instability Training Improves Joint Proprioception

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 …

Multi-planar Strengthening Appears Important in Rehabilitation

Multi-planar Strengthening Appears Important in Rehabilitation

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

A weak core is considered paramount for athletes, as it is the “engine” of the body. It is also believed a weak core increases the risk of injury. The core is defined as the muscles which surround the lumbopelvic region and includes the abdominals anteriorly, the paraspinals and gluteals posteriorly, the pelvic floor musculature inferiorly, the hip abductors and rotators …

Future of Swimming Training

Future of Swimming Training

Dr. GJohn Mullen Blog, Competition, Latest&Greatest, Training 2 Comments

Smart technology is on the verge of dramatically enhancing swimming performance, be ready for the revolution. Swimming is one of the most biomechanically difficult sports. Unlike other sports, swimming works against water while in a horizontal position. The unfamiliar horizontal position makes all stroke corrections more difficult. Water also creates resistance during any motion, making improvements harder! This motion creates …

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 …

Low Intensity Exercise under Hypoxia: Hormonal Effects

Low Intensity Exercise under Hypoxia: Hormonal Effects

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

Blood flow resistance training has been suggested to improve muscle strength and size at lower loads due to similar hormonal releases compared to resistance training. This acute hypoxia has stemmed research on systemic hypoxia. Training in systemic hypoxic conditions is also suggested to improve growth hormone (GH) release. However, the effects of systemic hypoxic conditions have yet to be determined. …
