Aerobic Capacity after Contracting lnfectious Mononucleosis

Area of Science:

• Sports Medicine
• Infectious Diseases
• Exercise Physiology

Background:

• Infectious mononucleosis (mono) can significantly impact athletes, often leading to prolonged periods of prescribed inactivity.
• Extended rest can result in substantial detraining, affecting an athlete's physical condition and performance.
• Traditional recovery protocols for mono may not be optimal for athletic populations.

Purpose of the Study:

• To investigate the effects of early exercise initiation versus prolonged inactivity on aerobic capacity in athletes recovering from mononucleosis.
• To determine if prolonged bed rest is necessary for athletes after the resolution of infectious mononucleosis symptoms.

Main Methods:

• Sixteen cadets with mononucleosis had their aerobic capacity (VO2 max, METS, run time to exhaustion) measured post-fever.
• Nine cadets participated in a 2-week exercise program, while the remaining seven remained inactive.
• Aerobic capacity was re-assessed after an additional 2 weeks (4 weeks post-fever), with a case study monitored weekly and at 6 months.

Main Results:

• No significant differences in VO2 max, METS, or run time to exhaustion were found between the exercise and inactive groups.
• A case study showed no changes in aerobic capacity variables when monitored weekly for 4 weeks and at 6 months post-recovery.
• Aerobic capacity remained stable regardless of the prescribed activity level during the initial recovery phase.

Conclusions:

• Prolonged bed rest is not indicated for athletes recovering from infectious mononucleosis.
• Noncontact physical activities can be safely initiated as soon as an athlete becomes afebrile.
• Early return to activity may help mitigate detraining effects without compromising recovery.
