The effect of "warm-up" on exercise-induced asthma
Annals of Allergy
|April 1, 1979
Summary
A warm-up did not reduce exercise-induced asthma (EIA) in 18 young adults. The incidence and severity of EIA remained the same with or without a warm-up before exercise.
Area of Science:
- Exercise Physiology
- Respiratory Medicine
- Sports Medicine
Background:
- Exercise-induced asthma (EIA) is a common condition affecting athletes and active individuals.
- The role of warm-up protocols in mitigating EIA symptoms is not fully understood.
- Current recommendations for warm-up strategies vary, lacking definitive evidence.
Purpose of the Study:
- To investigate the effect of a standardized warm-up on the incidence and severity of exercise-induced asthma.
- To determine if a brief warm-up can prevent or reduce EIA symptoms following strenuous exercise.
Main Methods:
- Eighteen subjects with a history of EIA performed two exercise challenges: one preceded by a 3-minute warm-up (60% max HR) and one without.
- Exercise challenge involved 5 minutes of treadmill running to 85% of predicted maximum heart rate.
- Incidence and severity of EIA were assessed by monitoring symptoms and FEV1 (Forced Expiratory Volume in 1 second) decline.
Main Results:
- The incidence of EIA was 77.8% in both conditions (with and without warm-up).
- The mean decrease in FEV1 was 38.1% in both conditions, indicating similar severity of EIA.
- No significant difference in EIA occurrence or severity was observed between the warm-up and non-warm-up protocols.
Conclusions:
- The studied warm-up protocol (3 minutes at 60% max HR) did not effectively reduce the incidence or severity of exercise-induced asthma.
- Further research is warranted to explore the efficacy of longer, more intense warm-up strategies, potentially including interval exercise.
- The findings suggest that current warm-up guidelines for EIA may need re-evaluation.

01:20Asthma: Pathogenesis and Management
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

01:20Exercise and Cardiovascular Response
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:29Asthma-I: Introduction
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
01:24Asthma-III: Symptoms and Complications
Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

01:28Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
01:13Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
