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 1 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. …

Is HIT (High Intensity Training) useful for swimmers? Part 2

Is HIT (High Intensity Training) useful for swimmers? Part 2

Dr. GJohn Mullen Biomechanics, Blog, Dryland, Training 3 Comments

The physiology behind High-Intensity Training (HIT) The scientific evidence in support of high-intensity training has increased the number and quality of studies, especially those involving high-level athletes. It’s already known that a large number of swimmers, all over the world, are applying the basic principles of this scientific methodology using a large number of different strategies (including ultra-short race-pace training (USRPT) and …

1. Please introduce yourself to the readers (how you started in the profession, education, credentials, experience, etc.). My name is Christoph Zinner and I studied sports science at the German Sports University Cologne (2009). Here I did my Ph.D. in exercise science in 2013. In 2014 I worked at the Swedish Winter Sports Research Center as a post-doc. In 2015 I will …

Is there a 'Perfect' Swimming Warm-up?

Is there a ‘Perfect’ Swimming Warm-up?

Dr. GJohn Mullen Blog, Dr. John Mullen, Dryland, Training 1 Comment

Warm-up and warm-down are confusing subjects in the realm of swimming. Different teams use different strategies with different success. But, what are the best means to warm-up? Is there a ‘perfect swimming warm-up’? What do you do if you don’t have a warm-up or warm-down pool available? Is warm-up/down even important? Do age group swimmers even need warm-down? These questions …

Ankle Swimming Flexibility

Ankle Swimming Flexibility

Dr. GJohn Mullen Allan Phillips, Biomechanics, Blog, Dryland, Latest&Greatest, Training Leave a Comment

Background on Ankle Swimming Flexibility Improving ankle mobility in freestyle, backstroke, and the butterfly is often vexing for both swimmers and coaches. Some swimmers appear naturally blessed with mobile ankles. Others work madly to force plantar flexion (toes pointed down) but make little progress. Although plantar flexion and dorsiflexion (toes pointed up) are both needed for dynamic ankle mobility in …
