Friday Interview: On Inspiratory Muscle Fatigue

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

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

Groin Kick Syndrome

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

“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

Effects of Static Stretching on Power

Dr. GJohn Mullen Blog, Dryland, Training 4 Comments

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

Varied Warm-ups and Leg Press Performance

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

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 

Stretching Effects on Contralateral Muscle Strength 

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

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 …

Core Strength Effects on Extremity Power

Core Strength Effects on Extremity Power

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

A strong core is believed to be essential in swimming. Theories suggest the core helps connect the upper and low body and a strong core efficiently transfers forces through the extremities. Moreover, the endurance of the core is important for prevention of injury. Despite popular belief, there is minimal research supporting the notion of a strong core important for athletic …

Rest Interval and Bench Press Performance

Rest Interval and Bench Press Performance

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

Rest interval is a manipulated variable in resistance training. Rest intervals effects intensity, volume, exercise order, repetition velocity, and depends on an individual’s training goals, fitness levels, and energy system targeted for a response. Past studies have found reset interval length between sets and exercises has been shown to affect metabolism, hormones, and cellular immune response to an acute bout …

Effects of Endurance Exercise Training on Muscles

Effects of Endurance Exercise Training on Muscles

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

Endurance exercise training is a common mode of training for swimmers. This form of training causes many structural and functional adaptations that enhance capacities for skeletal muscle. It is believed, submaximal exercise (endurance exercise training), drives up VO2 and improves coupling between energy, but these properties reduce the rate of glycolysis and reliance of finite energy sources and increases exercise …

What Are the Effects of Ischemic Conditioning and Low-Intensity Exercise?

What Are the Effects of Ischemic Conditioning and Low-Intensity Exercise?

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

Over the past five years of evidence regarding ischemic conditioning has exploded. This form of training has unique Implication for swimming by providing another modifiable parameter to dry-land. Moreover, these devices have application in swimming, as ischemic conditions could be used during swimming. This form of training is still young, especially for prescribing parameters, but many researchers in Japan (where …

Electrical Stimulation's Impact on Sprinting in Swimmers

Electrical Stimulation’s Impact on Sprinting in Swimmers

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

Background on Electrical Stimulation Swimming is a unique sport where resistance training effectiveness is uncertain secondary to the lack of land for force production. Also, swimming is a highly neural sport, requiring high amounts of “feel” and resistance training may disrupt this sensation and impair biomechanics. A few studies have correlated improvements in upper extremity resistance training and sprint improvements. …
