Impact of exercise programs among helicopter pilots with transient LBP

Area of Science:

• Aerospace Medicine
• Musculoskeletal Health
• Exercise Physiology

Background:

• Flight-related low back pain (LBP) is prevalent among helicopter pilots.
• Prolonged sitting during flights may weaken lumbar trunk (LT) muscles, leading to pain.
• This study investigated the efficacy of structured training for improving muscular function and reducing LBP in pilots.

Purpose of the Study:

• To evaluate the impact of two distinct 3-month exercise programs on LT muscle function and LBP in helicopter pilots.
• To assess improvements in lumbar multifidus muscle (LMM) contractility and endurance.
• To determine the effects of training on pilot-reported pain, function, and quality of health.

Main Methods:

• 39 helicopter pilots with reported LBP were randomized into two training groups (Program A: general LBP exercises, Program B: specific LT endurance exercises).
• Assessments included questionnaires for pain and function, LT muscular endurance tests, and ultrasound of LMM contractility.
• Data were collected pre- and post-intervention.

Main Results:

• All participants showed improved LMM contractility and endurance post-training.
• Significant improvements in function and quality of health were observed across all participants.
• Program B yielded significant reductions in pain and enhanced function and quality of health compared to Program A.

Conclusions:

• A 3-month exercise program effectively improved muscle endurance in helicopter pilots.
• Pilots participating in the exercise programs reported enhanced function and quality of health.
• Targeted training (Program B) demonstrated superior outcomes in pain reduction and functional improvement.
