"For every sport and fitness category described in the following sections, inspiratory muscle training (IMT) will improve exercise tolerance or performance by delaying the onset of the inspiratory muscle metaboreflex and reducing the perception of breathing and whole-body effort. These sections summarize the additional benefits.
Exercise and Fitness
For those engaged in general fitness training, IMT will make exercise feel easier, which enables people to maintain higher exercise intensities for longer durations. This enhances the fitness gains and caloric expenditure of general fitness conditioning.
The rate of perceived recovery will also improve, which will enhance the ability to maintain the tempo of activity during exercise-to-music classes and the intensity of circuit training. The enhancement of core stability will reduce injury risk and improve weight training.
Weight trainers will benefit from improved core stability, which may produce an improvement in maximal lift performances for lifts where trunk stiffness and stability contribute to the ability to overcome a load (e.g., Olympic lifts).
A wide range of endurance sports are reviewed here, but the principles that have been applied can be adapted to suit any sport.
IMT will improve the runner’s ability to maintain a deeper, slower breathing pattern. It will also enhance the efficiency of respiratory and locomotor coupling (entrainment), enhance core stability (reducing spinal loading and improving leg drive efficiency), and improve postural control (balance). IMT may also reduce the risk of developing a side stitch.
IMT will improve the cyclist’s ability to maintain a deeper, slower breathing pattern. It will also enhance the efficiency of respiratory and locomotor coupling (entrainment) and enhance core stability (reducing spinal loading and knee stress and improving pedaling efficiency). IMT will also allow the inspiratory muscles to operate more comfortably in extreme cycling positions (e.g., when using aerobars).
The addition of IMT to swim and other aquatic training will improve the swimmer’s ability to maintain a deeper, slower breathing pattern and will enhance the efficiency of respiratory and locomotor coupling (entrainment). IMT can also enhance the swimmer’s ability to inhale rapidly and to achieve and sustain high lung volumes. As a result, the swimmer’s body position and stroke mechanics will be improved. A decrease in the number of breaths per stroke will also be possible. In addition, the muscles of the trunk will be better able to meet the dual demands for breathing and providing propulsive force.
Those using scuba will also benefit from a deeper, slower breathing pattern, which reduces air use and extends cylinder wear time. Furthermore, free divers and surfers may also experience an improvement in breath-holding time. Breathing restrictions imposed by wet suits will also be easier to overcome or tolerate after IMT.
The addition of IMT to multisport training will provide the benefits summarized for each component. Most triathlons involve a wet suit swim, and IMT will enhance the swimmer’s ability to breathe efficiently and comfortably. Furthermore, the unique breathing-related disruption that occurs during the transition from cycling to running will be alleviated.
The addition of IMT to rowing training will improve the rower’s ability to maintain a deeper, slower breathing pattern; enhance the efficiency of respiratory and locomotor coupling (entrainment); and enhance core stability and trunk stiffness (reducing spinal loading and improving force transmission to the blade). Furthermore, improvements in intercostal muscle function and the ability to generate and maintain high intrathoracic pressure may reduce the risk of rib stress fractures. IMT will also allow the inspiratory muscles to operate more comfortably at the catch and finish positions.
People taking part in sliding sports have a number of factors influencing their performance, including the effects of altitude and the challenges associated with maintaining balance. IMT will improve their ability to maintain a deeper, slower breathing pattern. It will also enhance the efficiency of respiratory and locomotor coupling (entrainment), enhance core stability (reducing spinal loading and improving leg drive efficiency), and improve postural control (balance) and trunk stiffness. The ability to maintain aerodynamic postures for longer periods without the associated breathing discomfort is another benefit of IMT.
Hiking and Mountaineering
Hikers and mountaineers have to contend with the effects of altitude, the impact of carrying heavy backpacks, and the challenges associated with maintaining balance on unpredictable terrain. IMT will improve their ability to maintain a deeper, slower breathing pattern; enhance the efficiency of respiratory and locomotor coupling (entrainment); and enhance core stability (reducing spinal loading). The challenges to postural control (balance) imposed by carrying a backpack and by traveling on uneven terrain will be minimized by IMT, and trunk stiffness will be improved. In addition, the ability to overcome the resistance to normal breathing movements of the trunk that are induced by backpacks will be improved.
Team and Sprint Sports
Team sports are diverse in their challenges, but they all have three important factors in common: They involve repeated high-intensity efforts that drive breathing to its limits; they require the contribution of the upper body and the core-stabilizing system (e.g., fending off opponents, changing direction quickly, or passing objects to teammates); and they require tactical decision making at a time when the distraction from breathing discomfort is high. IMT will improve the rate of perceived recovery between sprints, which will enhance repeated sprint performance and the quality of interval training. These improvements in perceived recovery should enable players to maintain the intensity of their involvement in the match or game, rather than back off for a period of “cruising” recovery. In addition, the damping down of breathlessness will lessen the distraction that this sensation imposes on tactical decision making. Improvements to core stability will advance a player’s effectiveness during physical interactions with opponents (e.g., tackling, fending off) and in activities such as kicking and throwing. For contact sports and those that involve activities requiring the application of whole-body isometric forces (such as a rugby scrum), players will benefit from the increased ability of the inspiratory muscles to function as breathing muscles. This is important in situations where the demand for breathing is high but the requirement for maximal core-stabilizing activity is also present. Finally, in those contact team sports requiring the use of mouth guards and other protective equipment, IMT can improve breathing comfort and reduce the risk of inspiratory muscle fatigue that results from the restrictions imposed by the equipment.
Racket, Striking, and Throwing Sports
Sports falling under this heading most commonly require the participants to use an implement to strike a ball—such as a racket (e.g., tennis, squash, badminton), club (e.g., golf), or bat (e.g., baseball, softball, cricket)—or they may be sports that involve throwing a ball (pitching and bowling). In the case of racket sports, the player is required to direct the ball within the bounds of the court using a range of strokes. Matches are fast paced, requiring speed, agility, and skill. In contrast, in sports such as golf or baseball, the player is able to square up to the ball or pitcher and is stationary as the ball is struck. These two scenarios create very different demands on the breathing muscles, but there are two common denominators: the involvement of the trunk musculature in providing a stable platform and in protecting the spine; the contribution of the entire trunk musculature to the task of accelerating a racket, club, bat, or arm.
After using IMT, players in racket sports will be able to maintain a higher tempo of performance during rallies, and they will experience a reduction in unforced errors. Rate of perceived recovery between rallies will also improve, which will enhance the ability to maintain and dictate the pace and tempo of the game. In addition, the damping down of breathlessness will lessen the distraction that this sensation imposes on tactical decision making. The enhancement of core stability and improved contribution of the trunk musculature to racket head speed and precision will increase the likelihood of aces and shots that are “winners,” as well as reduce the risk of injury.
Many of these sports require high levels of core stability and a contribution from the trunk musculature to the swinging of implements (such as clubs and bats) or the launching of projectiles (such as in field sports). Players in these sports will benefit from the enhanced function of the diaphragm and the enhanced contribution of the inspiratory accessory muscles to these movements. This will result in an increase in striking and throwing velocities. In addition, there will be a reduction in injury risk because of the enhanced spinal stability and the improved resistance of rib cage muscles to tearing."

"The Core Strength: Pilates for Triathletes" is a superb teaching of core strength taught and flexibility by June Quick, Certified Pilates Instructor, licensed Physical Therapist, Certified Athletic Trainer, and Stanford University Swimming consultant. She explains the movements that are demonstrated by a beginner and pro triathlete, how to make some more advanced movements when you're ready, and pre-hab to prevent common athletic injuries.
If you're new to triathlon and learn better visually, this is the package you want. It's like having a coach start you out. If you've been around the track a few times, pun intended, you may still pick up some technique and training pointers.
Championship Productions forwarded these to me for review and I'm glad they. I had not heard of them but these are some really good training resources.

"To move your body efficiently through the water, a coordinated movement of the arms and legs must occur. The key to this coordinated movement is a strong core, of which the muscles of the abdominal wall are a primary component. Besides helping to link the movement of the upper and lower body, the abdominal muscles assist with the body-rolling movements that take place during freestyle and backstroke and are responsible for the undulating movements of the torso that take place during butterfly, breaststroke, and underwater dolphin kicking.
The abdominal wall is composed of four paired muscles that extend from the rib cage to the pelvis. The muscles can be divided into two groups—a single anterior group and two lateral groups that mirror each other. The anterior group contains only one paired muscle, the rectus abdominis, which is divided into a right and left half by the midline of the body. The two lateral groups each contain a side of the remaining three paired muscles—the external oblique, internal oblique, and transversus abdominis (figure 5.1). In human motion and athletics, the abdominal muscles serve two primary functions: (1) movement, specifically forward trunk flexion (curling the trunk forward), lateral trunk flexion (bending to the side), and trunk rotation; and (2) stabilization of the low back and trunk. The motions mentioned earlier result from the coordinated activation of multiple muscle groups or the activation of a single muscle group.
The rectus abdominis, popularly known as the six pack, attaches superiorly to the sternum and the surrounding cartilage of ribs 5 through 7. The fibers then run vertically to attach to the middle of the pelvis at the pubic symphysis and pubic crest. The six-pack appearance results because the muscle is divided by and encased in a sheath of tissue called a fascia. The visible line running along the midline of the body dividing the muscle in two halves is known as the linea alba. Contraction of the upper fibers of the rectus abdominis curls the upper trunk downward, whereas contraction of the lower fibers pulls the pelvis upward toward the chest. Combined contraction of both the upper and lower fibers rolls the trunk into a ball.
The muscles of the two lateral groups are arranged into three layers. The external oblique forms the most superficial layer. From its attachment on the external surface of ribs 5 through 12, the fibers run obliquely (diagonally) to attach at the midline of the body along the linea alba and pelvis. If you were to think of your fingers as the fibers of this muscle, the fibers would run in the same direction as your fingers do when you put your hand into the front pocket of a pair of pants. Unilateral (single-sided) contraction of the muscle results in trunk rotation to the opposite side, meaning that contraction of the right external oblique rotates the trunk to the left. Bilateral contraction results in trunk flexion.
The next layer is formed by the internal oblique. The orientation of its fibers is perpendicular to those of the external oblique. This muscle originates from the upper part of the pelvis and from a structure known as the thoracolumbar fascia, which is a broad band of dense connective tissue that attaches to the spine in the upper- and lower-back region. From its posterior attachment, the internal oblique wraps around to the front of the abdomen, inserting at the linea alba and pubis. Unilateral contraction rotates the trunk to the same side, and bilateral contraction leads to trunk flexion. The deepest of the three layers is formed by the transversus abdominis, so named because the muscle fibers run transversely (horizontally) across the abdomen. The transversus abdominis arises from the internal surface of the cartilage of ribs 5 through 12, the upper part of pelvis, and the thoracolumbar fascia. The muscle joins with the internal oblique to attach along the midline of the body at the linea alba and pubis. Contraction of the transversus abdominis does not result in significant trunk motion, but it does join the other muscles of the lateral group to function as a core stabilizer. An analogy that often helps people grasp the core-stabilizing function of the muscles of the lateral group is to think of them as a corset that, when tightened, holds the core in a stabilized position."
Based on my experience as an athlete and a coach, I believe that the most valuable tool for any self-coached runner is an outline to guide decisions regarding which workouts are appropriate. The various types of training, ...
For some reason, triathlon attracts many who want to dig into the science of how to train, researching questions like, "Why do I need long runs AND short fast runs?" "Why should I train my core so much if I am not in a sit-up competition?" "Swimming is really the only technique-oriented sport, right?"
It all starts with base training. Marc Evans writes about base training in Triathlete's Edge. The following is an excerpt from his book reprinted here with permission from Human Kinetics.
Having spent many years training for fitness, it wasn't until the last few years I became aware of how delicate a balancing act it can be of knowing how and when to push yourself toward greater fitness and avoiding injury.
I have had many injuries and hope I've learned how to approach training with the long tern goal of staying healthy and injury free. I would often push myself too hard when I did not need to or it was not the right time to push. Maybe I did not give myself enough of a rest, either between intervals, sets, or laps. It absolutely is a science and the more I read and study, the more I am able to understand when and WHY I do the things I do.
With the idea of sharing that, I posed several questions to my physical therapy group that helps heal me, Elite Physical Therapy in Charlotte, NC. Kelly Floyd started this the group and Joe and Lesley have joined in the last year. They are immensely qualified and have vast sports experience themselves as well as treating patients of all ages and ailments.
I treasure their input and advice. Here's some advice I hope you can learn from as well.
What are the training rules of thumb and why are they important to follow?
Always break a sweat before stretching. Think of your cold muscle as a piece of bacon out of the freezer. You bend it and it breaks! Heat it up and it bends much easier!
It all starts with the core, the area of your body from your diaphragm to your groin. When running, jumping, cycling, swimming, or weight training, sitting, standing, bending, you name it, keep your spinal alignment perfect. Your spine is made to be stabilized, not twisted and bent. That’s what our other joints are for.
As any athlete knows, stretching is a very important component of a training regimen. There are a few well-regarded thoughts on stretching.
First - always warm up before stretching. My PT gave this example - imagine putting a rubber band in the freezer for a while and another one under warm running water. Which do you think will stretch more and stretch easier without breaking? The one that has been in warm water, of course. You do not have to run several miles to warm up enough to stretch but even walking a little bit until you feel your body more active. Your body will thank you with fewer injuries. Stretching cold is putting more stress on muscles that are not ready for it and are likely to create a circumstance where injury can occur.
Second - Understand that a long lean muscle that has been trained and stretched through its range of motion and can used through its range of motion is more useful and efficient than a shortened tight one.
In the last 3 years in particular, I have been working on my core strength and stretching. It helped my back problems, rehab after back surgery, swimming and stability. The core is the connector between your upper and lower body and should be thought of as a vital link for triathlon.
When you run, you swing your arms to counter to your leg movement. In the middle is the core. If you get out of your saddle while cycling, your hands grasp the handlebars while feet are in the pedals. The middle link is the core. The link between your stroke and your kick while swimming is your core.
As I increased my core strength, I noticed simple functional things in daily life also got easier like bending over, getting up and good posture. These make so much more of a difference now than when I was 18 years old.
