Learn about the impact of travel on athletes' performance.

Travel is a part of daily life for many athletes, especially elite athletes. It is common for athletes to make frequent short trips each week, and even some long trips (over 3 hours). Travel, while often necessary, can have negative effects on athletes' health and performance.

In addition to fatigue associated with stress and sedentary hours, travel often involves time zone changes and consequent alterations in circadian rhythms (a condition known as "jet lag") and is associated with a higher incidence of gastrointestinal problems. It's important to note that travel-related fatigue is not necessarily linked to jet lag.

Fatigue can occur on any flight due to many factors beyond a time zone change (such as physical inactivity, temperature changes, stress, etc.). However, jet lag is a more severe and long-lasting condition that occurs when crossing multiple time zones (more than three).

Effects of travel on athletes Numerous studies have demonstrated the negative effects of travel on athletic performance. For example, a study of rugby players found that in away matches (without actually changing time zones), athletes experienced greater leg fatigue and general numbness.1 However, the effects of travel on physical performance are often controversial due to its potential interference with the motivation to compete on a home or away field.

Another study simulated international (24-hour) and domestic (5-hour) travel conditions to avoid this motivation bias. They created a hypobaric chamber with mild hypoxia, as in an airplane, and compared these effects to a control condition. The results showed that the (simulated) international flight resulted in a decrease in both the quantity and quality of sleep,

Physical performance in the interval sprint test was reduced compared to the domestic flight and the control condition. Furthermore, perceived fatigue was more severe after the international flight, but travel can have consequences for performance and affect health.

A study published in the prestigious British Journal of Sports Medicine analyzed 259 rugby players over a 16-week competition period.

The results showed that the incidence of illness increased after an international flight (with a time difference of more than 5 hours). 3 Therefore, it is necessary to design strategies that reduce the negative effects of travel on athletes.

However, scientific evidence regarding the effectiveness of interventions to reduce jet lag in athletes is very limited or of poor quality. For example, a recently published systematic review sought to evaluate the effects of various pharmacological strategies (e.g., melatonin, sedatives, stimulants, etc.) and non-pharmacological strategies (e.g., exercise, sleep, nutrition, and light) on athletes.

After analyzing a total of 22 studies, the authors concluded that although some preliminary studies support the benefits of some strategies, the evidence is generally of low quality and has a high risk of bias.

Due to the lack of evidence, an international expert panel of physicians, scientists, nutritionists, and physical therapists recently published a consensus article in the prestigious journal Sports Medicine, outlining some recommendations to reduce the harmful effects of travel and jet lag.

The effect of stress on athletic performance Athletes are no strangers to the physical demands of their chosen sports, but what many may not fully realize is the profound impact stress can have on their performance and the potential for injury. We must recognize that stress is not just a mental burden; it can manifest physically and significantly impact an athlete's overall health and athletic ability.

The effect of stress on performance Understanding Stress Stress is a complex physiological response that involves the activation of the body's "fight or flight" mechanism. When the body perceives a threat, whether real or imagined, it releases stress hormones such as cortisol and adrenaline. While this response is necessary for survival in some situations, chronic exposure to stress can lead to a series of negative effects on an athlete's physical and mental health.

Risk of infection One of the most significant effects of stress on athletes is an increased risk of injury. Chronic stress can cause interruptions in nerve and muscle flow, muscle imbalances, abnormal movement patterns, and decreased flexibility. This increased muscle tension and joint stiffness not only impacts an athlete's range of motion but also increases the risk of injury. Without necessarily causing injury, these stressors can hinder an athlete's ability to perform precise movements, impacting their performance in sports that require agility, coordination, and precision.

delayed recovery Stress is associated with impaired immune function, which can lead to delayed recovery for athletes. When the body is exposed to chronic stress, its ability to repair and regenerate tissue is impaired. This can lead to prolonged recovery periods after intense training sessions or competitions, ultimately hindering an athlete's ability to maintain peak performance over time and increasing the risk of injury.

decreased concentration and attention Stress has a significant cognitive impact. It can impair an athlete's ability to focus and concentrate during training and competition. This loss of mental clarity can lead to poor decision-making, slower reactions, and an increased likelihood of making errors.

In sports where quick decisions can mean the difference between success and failure, maintaining mental clarity and focus is crucial. However, stress can cloud an athlete's judgment and hinder their ability to perform optimally.

Impact on sleep Good sleep is essential for an athlete's recovery and overall performance. Chronic stress can disrupt sleep patterns, leading to insomnia or sleep disturbances. The body's ability to repair and regenerate is impaired when an athlete doesn't get enough rest, contributing to an increased risk of injury and decreased athletic performance.

Managing Stress for Optimal Performance Recognizing and managing stress is crucial for athletes striving to perform at their best. Physical therapists play a vital role in this process by incorporating stress management techniques into their rehabilitation and training programs. This may include:

Stress Management to Improve Performance Breathing exercises: Teaching athletes how to perform deep diaphragmatic breathing can help activate the body's relaxation response, reducing muscle tension and promoting overall health.

Neuromuscular exercises: Guiding athletes through exercises that systematically contract and relax different muscle groups can help relieve chronic muscle tension associated with stress.

Mindfulness and Meditation: Incorporating mindfulness practices can enhance an athlete's ability to stay present, manage stress, and improve overall mental resilience.

Sleep hygiene: Educating athletes about the importance of maintaining regular sleep patterns and creating a conducive sleep environment can significantly contribute to reducing stress.

Counseling and Psychological Support: Collaborating with sports psychologists can provide athletes with mechanisms and strategies to cope with the mental challenges associated with their sport.
