Physical Exercise and Gut Dysfunction

Physical exercise places high demands on the adaptive capacity of the human body.

Strenuous physical performance increases the blood supply to active muscles, cardiopulmonary system, and skin to meet the altered demands for oxygen and nutrients.

The redistribution of blood flow, necessary for such an increased blood supply to the periphery, significantly reduces blood flow to the gut, leading to hypoperfusion and gastrointestinal (GI) compromise.

A compromised GI system can have a negative impact on exercise performance and subsequent post-exercise recovery due to abdominal distress and impairments in the uptake of fluid, electrolytes, and nutrients. In addition, strenuous physical exercise leads to loss of epithelial integrity, which may give rise to increased intestinal permeability with bacterial translocation and inflammation.

Ultimately, these effects can deteriorate post-exercise recovery and disrupt exercise training routine.

A review published in the American Journal of Physiology – GI and Liver Physiology, provides an overview on the recent advances in our understanding of GI physiology and pathophysiology in relation to strenuous exercise.

Various approaches to determine the impact of exercise on the individual athlete’s GI tract are discussed. In addition, the authors of the study elaborate on several promising components that could be exploited for preventive interventions.

As always, discuss all Health Recommendations with your Qualified Health Care Provider.

NSAIDs and Exercise Induced Intestinal Injury

Nonsteroidal anti-inflammatory drugs, NSAIDs, are commonly used by athletes to prevent anticipated exercise-induced pain, thereby putatively improving physical performance.

However, these drugs may have potentially hazardous effects on the gastrointestinal (GI) mucosa during strenuous physical exercise. The aim of a current study published in the journal Medicine and Science in Sports & Exercise, was to determine the effect of oral ibuprofen administration before exercise on GI integrity and barrier function in healthy individuals.

Nine healthy, trained men were studied on four different occasions: 1) 400 mg ibuprofen twice before cycling, 2) cycling without ibuprofen, 3) 400 mg ibuprofen twice at rest, and 4) rest without ibuprofen intake.

The study concluded that this is the first study to reveal that ibuprofen aggravates exercise-induced small intestinal injury and induces gut barrier dysfunction in healthy individuals.

The authors of the study concluded that nonsteroidal anti-inflammatory drugs consumption by athletes is not harmless and should be discouraged.

As always, discuss all medication usage with your qualified healthcare professional.

Prevalence of Abnormal Hip Findings in Asymptomatic Participants

The prevalence of abnormal magnetic resonance imaging (MRI) findings in an asymptomatic population has yet to be determined.

The purpose of a study published in the American Journal of Sports Medicine, was to assess a cohort of asymptomatic people to determine the prevalence of hip lesions.

Forty-five volunteers with no history of hip pain, symptoms, injury, or surgery were recruited for enrollment in this institutional review board–approved study. The subjects underwent a unilateral MRI scan with a Siemens 3.0-tesla scanner. The extremity side evaluated by MRI was alternated.

The study concluded that Magnetic resonance images of asymptomatic participants revealed abnormalities in 73% of hips, with labral tears being identified in 69% of the joints.

A strong correlation was seen between participant age and early markers of cartilage degeneration such as cartilage defects and subchondral cysts.
