Swimming Power: Relevance & Muscle Physiology - Part 1

By Deniz Hekmati.

Maximal power during a movement, such as the swim stroke, is determined by the contractile capacity of the muscles involved. The contractile capacity of a muscle is primarily influenced by fiber type composition (Cormie, McGuigan, & Newton, 2011). There are three main fiber types in humans—Type I, Type IIa, and Type IIx . . .

Warm-up: Practical Applications - Part 2

By Matt Bird.

In a typical warm-up, movement preparation is a key element to reducing injury and optimizing performance. Movement preparation includes activating small stabilizing muscles and engaging the large muscle groups that are needed to perform the movement. We use shoulder stabilization exercises, core stabilization (planks) and mobility squats to get the joints and muscles ready to perform work in the weight room and in the water.

Respiratory Muscle Fatigue: An Overlooked Topic In Swimming?

By Sean Kao.

...improvements in swimming performance following respiratory muscle training all used subjects that were adolescents or extremely mediocre swimmers (i.e Kilding et al. used male and female swimmers age ~19 with an average 100 SCM time of roughly 1:04). On the other hand, Mickleborough et al. and Clanton et al. used elite swimmers and found no difference. This may show that younger swimmers have potentially weaker inspiratory muscles or that mediocre level swimmers may need to improve their inspiratory muscles to improve their performance.

The 3 Areas of Swim Injuries: Research & Stats – Part I

By Deniz Hekmati.

80 Australian elite swimmers aged 13-25 completed 23 clinical tests, of which 53 swimmers underwent an additional MRI examination: 91% of the swimmers reported shoulder pain; 54% unilateral and 37% bilateral pain. During activity, 80% reported pain and 70% specified the pain occurring during overhead activity. Along with the pain, shoulder stiffness was seen in 68% of the swimmers. MRI findings show that supraspinatus tendon thickness is correlated with the level of training (P < .0001), years in training, and hours per week in training (P < .01).

Warm-up: The Science Behind It – Part 1

By Matt Bird.

A proper warm-up as defined by McGowan et al. (2016) includes four key objectives of a pre-competition warm-up as: 1) physiological, 2) kinesthetic, 3) mental, and 4) tactical. It is important for an athlete to have a wide assortment of exercises and procedures in order to properly prepare the body for any physical activity.

The 2 Laws of Torque: Application for Swimming

By Sean Kao.

Torque is simply moment arm multiplied by muscle force, or a rotational force. Kelly’s definition may be slightly ambiguous because he is referring to generating torque specifically within the hip and shoulder capsule to eliminate capsular slack within the socket, which tend.

1st Step of Dry-Land for Youth Swimmers

By Deniz Hekmati.

Figure 2, by Kreamer and colleagues, illustrates an overlook on neuromuscular development throughout an athletic lifetime. It is clear that a young athlete should first and foremost have fun. If a balance can be found between fun and instructive, we can be setting young swimmers up for an intense teenage era of training.

Core Work Exercise Selection

By Sean Kao.

Often, I find myself walking onto a pool deck witnessing swimmers doing an endless number of core exercises, such as crunches and sit-ups. As a swimmer and coach, I realize the necessity of having a strong core. Many swimmers believe that more crunches will equal stronger abs.

Pre-Meet Routine

By Byron Shefchik.

If our cells receive nutrients that are unfamiliar, it will trigger other processes that in turn will create enzymes and binding protein receptors that your body may not need pre-meet. That just takes more energy from you. You have most likely heard, “don’t shock your system,” and this is very much like it, but knows you know some reasoning behind it.

Pre Swim Shoulder Warm-Up

By Ashlyn Karosas.

It is no secret that most swimmers have or have had on some level a shoulder injury. In fact, a 2010 study illustrated tha 91% of elite swimmers between the ages 13-25 have reported shoulder pain at least once in their careers. The excessive swim volume and constant shoulder rotation for hours a day and for several years causes wear and tear to the muscles and ligaments around the shoulder joint.
