Thoracolumbar spinal manipulation and the immediate impact on exercise performance

Area of Science:

• Sports Medicine
• Chiropractic Research
• Exercise Physiology

Background:

• Understanding the immediate physiological effects of chiropractic manipulative therapy (CMT) on exercise performance is crucial for athletes and clinicians.
• Previous research has not conclusively determined if CMT impacts key exercise response variables.

Purpose of the Study:

• To investigate the immediate effects of thoracolumbar chiropractic manipulative therapy (CMT) on exercise performance.
• To measure changes in blood lactate concentration, exercise heart rate, and rating of perceived exertion during a graded exercise test (GXT).

Main Methods:

• A randomized, crossover design study involving 20 healthy college students (10 male, 10 female).
• Participants underwent a treadmill GXT 5 minutes after either prone Diversified T12-L1 CMT or a sham (no CMT) condition, separated by a 1-week washout period.
• Outcome measures including blood lactate, heart rate, and perceived exertion were recorded at each stage of the GXT until maximal effort was achieved.

Main Results:

• No statistically significant differences were observed in blood lactate concentration, exercise heart rate, or rating of perceived exertion between the CMT and no-CMT conditions.
• The data indicated no immediate impact of thoracolumbar CMT on the measured physiological responses during the GXT.

Conclusions:

• Thoracolumbar chiropractic manipulative therapy (CMT) does not appear to immediately enhance exercise performance in healthy college students.
• Further research may be warranted to explore potential delayed effects or impacts in different populations.
