“…11 The presence of illnesses such as upper respiratory tract infections (URTIs) is of great concern for team-sport athletes, given their infectious nature and the potential negative influence on performance and wellbeing. 12 Thus, these athletes should be appropriately monitored to identify periods when they are at increased risk of illnesses. 10,13,14 There is limited research describing the influence of factors such as training and competition demands on the incidence of illness in professional team-sport athletes.…”

word count: 228Text-only word count: 3303 Number of tables: 2 Number of figures: 4 2 Abstract Purpose: The aim of this study was to identify contributing factors to the incidence of illness for professional team-sport athletes, utilizing training load (TL), self-reported illness and wellbeing data. Methods: Thirty-two professional rugby league players (26.0 ± 4.8 yr; 99.1 ± 9.6 kg; 1.84 ± 0.06 m) were recruited from the same club. Players participated in prescribed training and responded to a series of questionnaires to determine the presence of self-reported illness and markers of wellbeing. Internal-TL was determined using the session rating of perceived exertion (sRPE) method. These data were collected over 29 weeks, across the preparatory and competition macrocycles. Results: The predictive models developed recognized increases in internal-TL (strain values of >2282 AU, weekly-TL >2786 AU and monotony >0.78 AU) to best predict when athletes are at increased risk of self-reported illness. In addition, a reduction in overall wellbeing (<7.25 AU) in the presence of increased internal-TL as previously stated, was highlighted as a contributor to self-reported illness occurrence. Conclusions: These results indicate that self-report data can be successfully utilized to provide a novel understanding of the interactions between competition-associated stressors experienced by professional team-sport athletes and their susceptibility to illness. This may assist coaching staff to more effectively monitor players during the season and to potentially implement preventative measures to reduce the likelihood of illnesses occurring.

“…Weidner et al demonstrated the effects of a URTI caused by rhinovirus 16. A wellconducted trial showed no significant difference between those inoculated with the virus versus those receiving placebo at days 2, 5, and 8 in pulmonary function, VO 2 max, and exercise to fatigue [9]. This supports the concept that there are few physiologic changes in the athlete's body during an uncomplicated URTI, and athletes should be considered medically appropriate for return to participation even while symptomatic.…”

The hearts and lungs of athletes are subject to damage from a wide array of infections and environmental factors. Mild to moderate exercise has been shown to be beneficial to overall health, and strenuous exercise simply requires proper rest and rehabilitation to ensure its beneficial effects as well. Simple colds and URTIs are very common in athletes and do not usually require significant intervention. Any suspected cardiac infection mandates a thorough evaluation and proper management to prevent catastrophic consequences. High altitudes can be helpful in enhancing performance, but caution must be exercised at even modest altitude to prevent serious complications. With diving, participants should know their time limits and ascend properly to avoid serious complications. Keeping the heart and lungs in a good state of health is a major priority for the weekend warrior and world-class athletes alike. A thorough knowledge of infections and environmental issues in the cardiopulmonary health of athletes should always be of highest priority.

“…This finding adds to a trend that moderate exercise during a URTI does not affect symptom severity or duration. 10 Further, moderate exercise during a URTI does not affect pulmonary function test and exercise responses, 19 running gait, 20 or physical performance. 21 Similar studies with other forms of exercise (for example, weight training), other populations (for example, young and old, labourers), and fitness levels (for example, highly fit) warrant further investigation.…”

Objective: To determine if exercise training affects the severity and duration of a naturally acquired upper respiratory tract infection (URTI) in sedentary subjects. Methods: Subjects were sedentary volunteers (two or fewer days a week of exercise for less than 30 minutes a day for the previous three months), 18-29 years of age, with a naturally acquired URTI (three to four days of onset). All subjects were screened-for example, asthma, hay fever-by a doctor and were afebrile. Volunteers were alternately assigned to an exercise (EX) group (four men, seven women) or a non-exercise (NEX) group (three men, eight women). Subjects in the EX group completed 30 minutes of supervised exercise at 70% of target heart rate range for five days of a seven day period. For the initial screening, and every 12 hours, all subjects completed a 13 item symptom severity checklist and a physical activity log. Cold symptom scores were obtained until the subjects were asymptomatic. Significance was set at p<0.05. Results: There were no significant differences between EX and NEX group mean symptom scores for the morning and evening reporting periods. There were also no differences between the groups for the mean number of days from the baseline symptom score to when the subjects were asymptomatic. There were no differences between physical activity levels, other than what was assigned in the EX group. Conclusion: Moderate exercise in sedentary subjects with naturally acquired URTI probably does not alter the overall severity and duration of the illness. Previously sedentary people who have acquired a URTI and have just initiated an exercise programme may continue to exercise.
