Asthma and Sports What to do in front of an Asthma Attack?
What is asthma?
The Asthma is a disorder of the airways that occurs chronic inflammatory thereof and may involve various types of hypersensitivities stimuli. Although often begins in childhood asthma can affect people of all ages.
What are the Symptoms of Asthma?
Among his most repeated symptoms include:
- Intermittent respiratory distress
- Difficulty breathing
- Chest tightness
Why Asthma occurs?
Directly resulting from the narrowing of lower airways, caused by a combination of processes: inflammation, excessive mucus production and smooth muscle dysfunction in the lower airways.
Asthma begins when the immune system develops an exaggerated response to an allergen or external agent:
- Low air temperature (reduced availability of oxygen in the air)
- Snuff and smoke
This early response is associated with abnormal bronchoconstriction occurs within minutes of exposure to the allergen, often peaking within 2-3 hours after initial exposure, and extended to 3-7 hours (can last even 24 hours to consider acute allergic asthma)
When asthma persists over time due to irritability smooth muscle hyperplasia or abnormalities in the contractile functions of smooth muscle cells of the airways. This is perhaps the most difficult type to treat asthma from the point of view of the exercise.
Exercise in asthmatics may result in increases in airway resistance causing undesired bronchoconstriction induced by exercise (BIE). However, with proper progression, exercise improves overall asthma management helps improve cardiorespiratory function and quality of life in general.
The BIE is present in 60-90% of asthmatics of all ages, it is estimated that 1 in 5 people with asthma undiagnosed, and 50% of elite endurance athletes may go through
Sport with Asthma
The responsiveness of asthmatic someone will be lowed and slower, assuming that one of the main obstacles faced by patients for exercise: “I find it hard to start.” However, this should not be an excuse “per se” but a constraint to the type, intensity, duration and volume of exercise; as performed should be performed, including aerobic and against resistance (weights).
Asthmatics Training Benefits
It is true that the benefits of training resistance for the disease will be greater than the weight training, but do not forget the joint improvement of both methods:
Specifically, weight training, and always he is warning that the best way to plan is individualizing, follow these loading patterns at the beginning of a program and gradually increase the level (decreasing breaks, increasing the weekly frequency, increasing intensity):
- 2-3 days per week.
- Alternating upper limb and lower limb (move towards basic exercises that demand more cardiovascular requested).
- perceived intensity: 5-6 on the Borg scale (over a maximum of 10 points perceived exertion).
- More extended rest intervals: 3-4 minutes
As for the aerobic training, fatigue and BIE intro-training it can be solved by performing exercises with intervals manipulation refractory period between intervals through routines reheating can partially reduce the level of BIE in asthmatics.
This has demonstrated from the clinical point of view and quality of life in:
- Significant increases in aerobic capacity (peak VO2 or VO2max: 5.57 ml/kg/min for 6 – month intervention).
- Improved maximum expiratory (6.0 L / min in 6 months protocol).
Considerations for Athletes with Asthma
Sports Recommendations for Asthmatics
- Do not practice if you have symptoms and should take up rescue medication (short-acting bronchodilators).
- Best practice sport indoors and avoid rainy and cold days.
- Activities most recommended those with ambient warm air and humidity (gym, swimming).
- Patients with chronic respiratory processes can perform aerobic exercise, not intense (walks at intervals less demanding activities for the respiratory system between sets).
- Always make coach feedback based on the scale of perceived exertion and dyspnea.
How to act in an Asthma Attack?
Some people with asthma may go long periods without having an asthma attack or other symptoms, interrupted by the worsening of symptoms due to exposure to asthma triggers or due to exercise-induced asthma. Mild asthma attacks are generally more common. Airway open in a few minutes or a few hours after treatment.
Symptoms of an Asthma Attack
The signs and symptoms of exercise-induced bronchoconstriction may begin during or a few minutes after exercise, as well as persister even longer. Signs and symptoms that may be indicative of an asthma attack include:
- Shortness of breath or wheezing rapidly worsening
- Difficulty breathing
- Strong chest tightness
- excessive fatigue during exercise
- No improvement even after using an inhaler prescribed for asthma attacks
What to do in an Asthma Attack?
- Leaving the activity
- Sit and try to breathe slowly and steadily.
- First of all, stay calm, because the panic is worse.
- Take a breath inhaler every 30-60 seconds, to a maximum of 10 puffs.
If despite these steps, we do not improve, we call an ambulance or seek medical service.
