Tennis Players’ Endurance Improves after POWERbreathe IMT

New research shows tennis players’ endurance and strength improves after Inspiratory Muscle Training (IMT). The research from Pune, India, is in the International Journal of Current Research (February 2018).

What affects tennis performance

The main characteristics of this game are intense bouts of running, such as sprinting to reach a ball. Consequently, breathing is driven to its highest levels. And this induces extreme breathlessness. This affects performance.

In order to continue to play effectively while maintaining a high level of skill performance, breathing mustn’t hinder performance.

Breathing effort in tennis

Playing tennis involves using your breathing muscles in your torso to brace and twist during a racket stroke. Also, experienced players use their inflated lungs to brace the impact of the ball and racket. This helps them to control the release of air from their lungs and optimise the transmission of force. However, breathing muscle fatigue impairs this control. Thankfully though, breathing muscle strengthening training will improve this. Using a device that specifically trains the breathing muscles, the inspiratory muscles, is the easiest way of doing this. These are called Inspiratory Muscle Training (IMT) devices, such as POWERbreathe IMT. And training your breathing muscles to become stronger can help with a player’s postural control and movement too.

Research into players’ endurance

The research from Pune highlights the fact that tennis matches feature high-intensity, short- duration bouts of extreme activity with a short rest time. And it’s the competition of blood flow between the arms and legs and the breathing muscles which ultimately increases breathing fatigue.

For this study, researchers use the POWERbreathe KH1 Inspiratory Muscle Training (IMT) device to strengthen participants’ breathing muscles. Furthermore, each participant performed a prescribed protocol for using the device for five days over four weeks. Researchers were aiming to assess the effect of IMT on cardiovascular endurance in lawn tennis players.

Research findings

The findings of this latest research show there to be,

“significant improvement in cardiovascular endurance and strength in lawn tennis players after progressive inspiratory muscle training.”

How to improve tennis performance

POWERbreathe IMT specifically targets the breathing muscles, strengthening them by around 30-50%, significantly improving performance and helping to eliminate breathing fatigue. And these findings are a result of studies with tennis players who, after IMT, took less time to recover and were ready sprint maximally again more quickly.

 

 

Improve your tennis performance with POWERbreathe

Tennis requires a blend of aerobic fitness, strength, power and agility, with the intensity of an average game ranging from just 20% of maximal oxygen uptake, to almost 90%. The duration of a rally in tennis is the main determinant of exercise intensity (longer rallies = higher intensity). When you then add on the fact that players may be on court for hours at a time, you can begin to understand what it requires to be an elite tennis player. The short, intense bouts of running that characterise tennis also have much in common with other ‘repeated sprint sports’ such as football, rugby, basketball and hockey where breathing is driven to its highest level leading to extreme breathlessness. Research shows POWERbreathe improves recovery Avoiding the debilitating effect of breathlessness may not be a matter of simply needing to get fitter, in fact research conducted at the University of Birmingham showed that training the inspiratory muscles using POWERbreathe improves the rate of recovery during a repeated sprint test. The tennis players involved in the study took less time to recover and were ready to sprint maximally again more quickly after POWERbreathe Inspiratory Muscle Training (IMT). Research also showed that the demands of breathing during exercise are so high that the vital inspiratory muscles experience fatigue. POWERbreathe IMT helps here too, because strengthening the inspiratory muscles also makes them less prone to fatigue. Breathing muscles contribute to tennis match-play in a less obvious way too Tennis involves using the breathing muscles of the torso to brace and twist during a racket stroke. Experienced tennis players use their inflated lungs to brace the impact of the ball and racket, optimising the transmission of force. The ‘grunt’ heard during serve and shot is the controlled release of air from the lungs and this requires fine control of the breathing muscles. Control is impaired by fatigue and improved by inspiratory muscle strengthening with POWERbreathe.

Non-Asthma Related Breathing Problems In Athletes

This BASES Expert Statement looks into exercise respiratory symptoms, such as wheezing, tight chest, difficulty breathing, shortness of breath and coughing which are commonly reported by athletes.

These non-specific symptoms need to be assessed in order to confirm or eliminate the presence of cardio-pulmonary causes.

There is a high prevalence – 70% – of asthma and exercise induced bronchoconstriction (EIB) in sports with high breathing requirements, and it has been assumed that exercise-induced respiratory symptoms in these athletes is due to asthma or exercise-induced-asthma (EIA).

Symptoms however are misleading and this Expert Statement looks at these differential causes of exercise respiratory symptoms: Exercise-Induced Laryngeal Obstruction (EILO) and Dysfunctional Breathing.

Interventions are then discussed which include breathing pattern retraining and inspiratory muscle training and finally conclusions are made.

Proper Breathing – POWERbreathe Can Help

Your primary breathing muscle is your diaphragm; a dome shaped thin sheet of muscle separating your rib cage from your abdomen.

When you inhale this dome shape flattens out as your diaphragm contracts, pushing down on the contents of your abdomen (your gut) and increasing the space in your chest cavity.

Because your gut has to go somewhere as your diaphragm descends, it forces it down and out and your tummy expands. Because of this, this natural, healthy and proper way of breathing is often referred to as abdominal breathing or diaphragmatic breathing.

If you do already have a good breathing technique it can often go awry when you start exercising as you demand more air and your breathing increases to compensate. This is when your breathing technique can change from good diaphragmatic breathing to reverse breathing i.e. pulling in your tummy as you breathe in and letting your tummy go as you breathe out.

Because your diaphragm is a muscle, you can train it like any other muscle to become stronger and helping you retain that good diaphragmatic breathing even when pushed to your limit. POWERbreathe targets your inspiratory muscles – not only your diaphragm but also your intercostal muscles, the tiny muscles in between your ribs, which are recruited during a slightly forced respiration.

You’ll notice when training with POWERbreathe that you have to work harder to breathe in. This is the effect of resistance training acting on your inspiratory muscles. When breathing out, POWERbreathe offers no resistance because when you exhale normally, your diaphragm and intercostals naturally relax and move back up, pushing the air from your lungs.

Effects of Inspiratory Muscle Training on Resistance to Fatigue of Respiratory Muscles During Exhaustive Exercise
M. O. Segizbaeva, N. N. Timofeev, Zh. A. Donina, E. N. Kur’yanovich, N. P. Aleksandrova

This study, published in Body Metabolism and Exercise – Advances in Experimental Medicine and Biology (Volume 840, 2015, pp 35-43) concluded that IMT elicits resistance to the development of inspiratory muscles fatigue during high-intensity exercise.

PURPOSE:

To assess the effect of inspiratory muscle training (IMT) on resistance to fatigue of the diaphragm, parasternal, sternocleidomastoid and scalene muscles in healthy humans during exhaustive exercise.

The sternocleidomastoid muscle flexes the neck and helps with the oblique rotation of the head. Also, the muscle helps in forced inspiration while breathing, and it raises the sternum. As for forced inspiration, the muscle also works in concert with the scalene muscles in the neck. The scalene muscles are lateral vertebral muscles that begin at the first and second ribs and pass up into the sides of the neck. There are three of these muscles. (SOURCE: Healthline.com)

CONCLUSION:

“The study found that in healthy subjects, IMT results in significant increase in MIP (+18 %), a delay of inspiratory muscle fatigue during exhaustive exercise, and a significant improvement in maximal work performance. We conclude that the IMT elicits resistance to the development of inspiratory muscles fatigue during high-intensity exercise.”

What causes exercise-induced asthma?

The reason why asthma symptoms may be brought on during exercise has not been completely established but it is thought that because breathing becomes heavy and we breathe faster when we exercise, the linings of our airways narrow and dry out. Also weather conditions and allergies, such as an allergy to pollen, can also trigger asthma-like symptoms when exercising.

Recognising exericse-induced asthma (EIA)

Diagnosis is often made after symptoms, such as wheezing and a tight chest, are experienced during exercise, but this can result in either over-diagnosis, where athletes report symptoms but DO NOT have narrowing of the airways, or under-diagnosis where athletes who’re asymptomatic (showing no symptoms) DO have narrowing of the airways which affects their performance.

The scenarios above are supported in studies where elite athletes have been screened and shown to have EIA, such as reported by British Olympic Teams in the 2012 Olympics where it found that 25% of Team GB suffers from exercise-induced asthma. And at the 1996 Olympic games 20% of athletes reported asthma upon exercising.

Why screen for EIA?

The main reason is because exercise-induced asthma may be detrimental to an athlete’s performance, as it’s already been shown to reduce exercise capacity and running speed in colder environments which will not only affect an athlete during training but also during competition.

Treatment of EIA

Both pharmacological and non pharmacological therapies are currently successfully used to treat EIA, and studies have also highlighted the benefits of adjunctive intervention. POWERbreathe Inspiratory Muscle Training can be used as an adjunctive intervention, not only for daily training, but also as a respiratory warm-up prior to exercise.

Breathe deeply with POWERbreathe for more energy

Deep breathing reaches the deepest depths of your lungs, and by practicing POWERbreathe inspiratory muscle training you’ll be training your respiratory muscles to breathe deeply into your diaphragm, taking in as much air as possible, breathing more in per breath.

As you’re breathing in more air per breath, you’re receiving more oxygen into your body, giving you more energy.

Senior consultant at the National heart Institute, India, and Founder, SAANS Foundation in India, Partha Pratim Bose offers a good example of this,

“By deep breathing exercises you breathe more per breath. If you breathe more per breath you expand your lungs more, you receive more oxygen. You will feel more energetic and also save your breaths. For example, if you breathe 250 ml per breath and your requirement is 5 litres then you need 20 breaths per minute. If you breathe more breath say double i.e. 500ml then you will require only ten breaths. So by breathing deep you breathe less and you feel better and conserve energy.”

Thankfully you can train your breathing muscles to breathe deep, as your respiratory muscles respond in the same way as skeletal muscles do to a training stimuli as they undergo adaptations to their structure and function. POWERbreathe is one such training stimuli, using the principles of resistance training to strengthen the inspiratory muscles. Its pressure loaded inspiratory valve offers the resistance on the inhale, while an unloaded expiratory valve allows for normal, passive exhalation.

Breathing – your magic bullet to improved sports performance

Breathing properly could just be your magic bullet to improved sports performance and sporting achievements.

In an article about The Dangers of Dysfunctional Breathing, international performance consultant Brandon Marcello, Ph.D., MS, CSCS says, “Having improper breathing form is no different from having improper squat form.”

The article goes on to say that ‘when it comes to physical activity, breathing ineffectively can alter your performance’. Therefore breathing effectively will also alter your performance, but for the better!

POWERbreathe inspiratory muscle training (IMT) exercises your breathing muscles, improving their strength and stamina, reducing fatigue which in turn enables you to train harder, for longer and with less effort which ultimately translates into improved performance.

Metabolic reflection of respiratory muscles limiting athletic performance

 

We’re grateful to our friends Fit & Breathe Concept for bringing this article to our attention. It’s written by Germain Fernandez Monterrubio, Bachelor of Science in Physical Activity and Sport and can be found in its original language here: ‘El reflejo metabólico de la musculatura respiratoria como factor limitante del rendimiento deportivo’.

We’ve translated the original text as best we can (as follows), but if it is not entirely clear then you may also be interested in reading this research, published in The Journal (2007) of The Physiological Society, ‘Insights into the role of the respiratory muscle metaboreflex’.

Metabolic reflection of the respiratory muscles as a limiting factor in athletic performance

Numerous studies show ventilatory fatigue (the inability of the respiratory muscles to achieve preural given pressure) (Chicharro, 2010) is considered as a limiting factor in performance, especially in disciplines that require endurance (such as marathon, rowing, swimming , triathlon etc).

One of the limiting factors that future studies will focus on is that of determining the specific influence of Metabolic Reflection of Respiratory Musculature (RMMR) in different cases.

The RMMR initiates fatigue of the respiratory muscles, which through III and IV afferents reach the supraspinal level, triggering a sympathetic response by vasoconstriction of peripheral muscle locomotive, which intensifies the fatigue of active muscles and increases also perception of effort, contributing to the limitation of return linked to intense aerobic exercise. (Romer and Polkey, 2008).

In aerobic performance, the TOTAL energy demand is not a limiting factor (Santalla, 2009), the production of energy in the time given is the determinant of fatigue… the “metaboreflex”. Respiratory muscles induce a number of mechanisms by which respiratory muscle fatigue can affect exercise tolerance (Jack mackerel, 2010, Santalla 2010, Romer and Polkey, 2008), incurring a series of cardiorespiratory interactions:

Pulmonary level:

  • Fatigue contraction of the diaphragm and accessory muscles of respiration.
  • Increased reflexes activated metabolites.
  • Increased afferent discharge (track III and IV).

Muscular level:

  • Increased efferent sympathetic discharge.
  • Increased vasoconstriction members.
  • Decreased oxygen transport.
  • Increased locomotor muscle fatigue.
  • Increased perception of effort.

In an experiment carried out with cyclists (Fischer, 2013) participants were induced to metaboreflex with post-exercise muscle ischemia, indicating that the increase in heart rate and the partial withdrawal of cardiac parasympathetic tone, is mainly attributed to increased cardiac sympathetic activity, and only after exercise with large muscle masses.

We speak of respiratory muscles (and mechanical); of autonomic nervous, central nervous system and cardiovascular system regulation in humans. A review by Douglas R. Seals raised the premise that if the RMMR represented the “Robin Hood” of the body to the locomotor muscles (Seals, 2001), determining that this reflex can have as its main objective the delivery of oxygen to the respiratory muscles, guarantees the ability to maintain pulmonary ventilation, adequate regulation of the gases in the blood flow and the pH and general organ homeostasis. The reflection is considered the “vital organ” responsible for supporting lung function and perfusion of the respiratory muscles, especially during physiological states in which there is competition for cardiac output, as in the exercise to maximum and submaximal intensities. This overrides the locomotor muscles.

Usually this phenomenon is found in those training for a sport or competition in which there will normally be a struggle between the respiratory muscles and the locomotor muscles for blood flow. Determining this is not so simple, as it also depends on the intervention of the central nervous system, which impinge on some physiological and psychological responses, such as the perception of effort. Generalizing, we can say that to focus on metabolic compromise reflects both muscles (respiratory and locomotor) at maximal or submaximal, rather than related to aerobic capacity.

‘Power Your Lungs!’ in Men’s Health (India) August 2013 edition

Our POWERbreathe friends and distributor, Greenwell Healthcare in India have sent us a copy of the Men’s Health India magazine (August 2013) which features an article about powering up your lungs with POWERbreathe.

Deckline Leitao is India’s leading personal fitness trainer and sports medicine expert, and he is the editor of the feature. Deckline is currently attached with the Prakash Padukone Badminton Academy where he is a performance enhancement specialist and coach. His role is to work on successfully improving the performance of the academy’s national and international players, but he also trains and consults for elite athletes from various other disciplines too, including boxing and athletics.

Deckline is also on the advisory board of Men’s Health magazine where he writes regular fitness features on a variety of topics such as training technique and sports injury etc.

In this feature, ‘Power Your Lungs!’, Deckline reports, “Having met exercise physiologists from the UK that promote it (POWERbreathe) and after seeing the results first-hand, I’m quite certain that this is indeed the best drug-free method to strengthen your lungs and diaphragm naturally. The device has come into the open after a substantial amount of research and development and the results speak for itself.”

“All my top players at the Tata Prakash Padukone have seen tremendous results over the past few months, after using this product.”

“Now that it has officially been launched in India I would confidently say that if you want to simply improve your stamina and endurance in marathons, mountaineering, cycling or even if you are simply seeking to max out your cardio, you should be using it!”

Because badminton involves short, intense bursts of running, breathing is driven to its highest level and can quickly induce breathlessness which can hinder performance. So training the breathing muscles to become stronger with POWERbreathe will provide the player with the stamina to get them through the game.

Stronger breathing muscles will mean that the player is able to brace the impact of the ball on the racket and power off the returning shot. Without stronger breathing muscles, the returning shot will be impaired by inspiratory muscle fatigue. POWERbreathe targets the inspiratory muscles, exercising them to improve their strength, stamina and power.

Read more about why you should incorporate POWERbreathe inspiratory muscle training into your badminton training, or if you’re a badminton player already using POWERbreathe, then please leave a comment here or on the POWERbreathe Forum, Facebook or Twitter as we’d love to hear about how you’ve benefited from this breathing training.
