[Intraocular pressure variation after submaximal strength test in resistance training]

Area of Science:

• Ophthalmology
• Sports Medicine
• Physiology

Context:

• Intraocular pressure (IOP) regulation during physical exertion is crucial for eye health.
• Understanding the physiological responses to submaximal strength testing is important for athletes and clinicians.
• Previous research has explored IOP changes during various exercises, but specific data on submaximal strength tests in college students is limited.

Purpose:

• To investigate the effect of submaximal strength testing on intraocular pressure (IOP) in college students.
• To quantify IOP changes before and immediately after a standardized strength assessment.
• To determine if significant IOP variations occur following resistance training exercises.

Summary:

• A study involving 145 Physical Education freshmen measured IOP using a Perkins tonometer before and after a one-repetition-maximum strength test.
• The strength test included exercises like bench press, pulldown, shoulder press, arm curl, and leg press.
• Results indicated a statistically significant decrease in IOP in both right (13.48 to 10.20 mmHg) and left eyes (13.13 to 9.74 mmHg) post-exercise (p<0.001).

Impact:

• The findings suggest that submaximal strength training leads to a relevant IOP reduction in young, healthy adults.
• This information can inform exercise protocols and eye safety guidelines for individuals engaged in strength training.
• Further research could explore the long-term effects and mechanisms behind IOP changes during resistance exercise.
