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. …
Dual Task Core Training Increases Core Stability
Many core exercises are used with the goal of improving core stability and decreasing low back pain. This study used a control group and compared it to a novel exercise. What was done Forty patients with low back pain (~50.35 years; M=19, F=21) performed either the drawing in the abdominal wall (control) or the ankle dorsiflexion in addition to drawing …
Instability Training Improves Joint Proprioception
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 …
Multi-planar Strengthening Appears Important in Rehabilitation
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 …
Effects of Barbell Deadlift Training on Submaximal Motor Unit Recruitment for the Quadriceps
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 …
Friday Interview: On Inspiratory Muscle Fatigue
Below is an interview with Alex Burtch, a coach who will be on the Elite Swimming Science Dryland Call. This interview discusses a missing element of many dryland programs, inspiratory muscle fatigue. Alex Burtch is a graduate of the Masters in Exercise Physiology program at the University of Louisville. He has worked in personal training, group fitness and sports specific strength and …
Groin Kick Syndrome
“Fast feet” “Get those feet moving” “Bubble, Bubbles! My grandma could kick faster…and she’s been dead for 20 years!” These expletives are thrown around the pool deck more than a kickboard slicing through the air like a Frisbee. In swimming fast feet are associated with fast swimming, however, fast hands don’t always correlate with fast swimming. In regards to the upper body, distance per …
Effects of Static Stretching on Power
Stretching is a commonly used method thought to improve muscle length. Contrary to belief, there is a lack of studies correlating stretching with improved muscle length. Moreover, stretching lacks the research behind many of its glorious claims (injury prevention, sports performance, etc.). In fact, a couple of studies indicate being more flexible is an injury risk. This purpose of this …
Varied Warm-ups and Leg Press Performance
The precise warm-ups for dry-land and swimming are unclear areas. Finding the balance between warming up the muscles, yet avoiding fatigue is a fine line, which often requires individualization. Despite this, many coaches request the same warm-up for each swimmer. Moreover, the specific event likely contributes to the amount of warm-up required for the athlete. For example, the warm-up for …
Stretching Effects on Contralateral Muscle Strength
Every athlete performs stretching. Unfortunately, little is unknown about this common practice. Recently, it has been suggested static stretching directly before sprint impairs speed and force production. Moreover, static stretching is not linked to injury prevention, despite popular belief. One area of static stretching that is beneficial is the strength. Multiple studies suggest repeated stretching on a specific muscle group …
