Swimming Warm-down Durations

Swimming Warm-down Durations

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

Warm-down is a difficult area of compliance. Many swimmers want to stretch in the shower and get out of the pool, unfortunately, warm-down is essential after practice, races, etc. I have discussed sprint swimming recovery and velocities for swimming warming down duration, but a recent study by Vescovi, Falenchuk, and Wells (friend of the site, read Friday Interview: Dr. Greg Wells) tackles warm-down …

If you enjoy this brief swimming review, consider supporting and purchasing the Swimming Science Research Review.  All 200-m strokes Result in Similar Inspiratory Muscle Fatigue  Inspiratory muscle fatigue (IMF) has been suggested as a contributor to fatigue in swimming. Now, Lomax et al (2013) have concluded IMF is similar across the four competitive strokes during a 200-meter race. “Inspiratory muscle fatigue …

Sprint Swimming Recovery

Sprint Swimming Recovery

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

Post-race recovery is needed for every swimmer. How much do you do? How fast do you do it? Do I wear my hi-tech suit…well I guess that doesn’t apply anymore. A study in the Journal of Strength and Conditioning Research compared passive recovery, recovery with low intensity (40% of the best 100-meter time) and high-intensity recovery (60% of 100 m time). Moreover …

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 …

Inspiratory Muscle Fatigue Impairs Latissimus Dorsi Strength

Inspiratory Muscle Fatigue Impairs Latissimus Dorsi Strength

Take Home Points on the Inspiratory Muscle Fatigue Impairs Latissimus Dorsi Strength Inspiratory muscle fatigue impairs latissimus dorsi activation, likely reducing swimming motor control and propulsion. Breathing is a frequent topic of discussion at Swimming Science. Before we get started, first brush up on: Inspiratory Muscle Fatigue Brief Swimming Review Volume 1 Edition 1 Lomax (2003) first demonstrated that a 200-m race results …

Rotational Power Test

Rotational Power Test

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

Core muscular endurance is a variable associated with low back pain rehabilitation. Core training is believed to improve ground sports performance but has not been confirmed in swimming. Rotational power is deemed an important variable in rotational power athletes. The correlation between rotational power and swimming success has yet to be proven, but many dry-land programs strive for improved rotational …

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 …

VO2 Kinetics on Heavy Swimming

VO2 Kinetics on Heavy Swimming

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

The intensity of exercise prescribed during a workout is typically defined based on the pulmonary oxygen uptake and blood lactate response to constant work. This is easily researched in running and cycling but is difficult in swimming. Therefore, many coaches prescribe intensity based on experience. A slow component of the VO2 kinetics is superimposed upon the rapid response, resulting in …

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 …
