[Research Review] High-Intensity Interval Running (HIIT) and Maximal Oxygen Uptake (VO2Max) Physiological Adaptations: A Recent Literature Review on the Relationship Between Clinical Medicine and Sports Performance (Article 796)

Reference Journal Source: Sports Medicine Journal • International Scientific Research Findings Review Series

In the research field of the Road Running Section, the latest biomechanical analyses and nutritional studies have revealed more subtle physiological codes. This research report is compiled from cutting-edge literature in Sports Medicine Journal, providing a detailed analysis of the performance of subjects in both the experimental and control groups. The findings are not only highly valuable for professional coaches but also provide a scientific basis for citizen runners pursuing their personal best (PB).

Aerobic Physiological Adaptations to High-Intensity Interval Training (HIIT)

High-Intensity Interval Training (HIIT) has been confirmed as one of the most effective methods for improving maximal oxygen uptake (VO2Max) within a short period. This study reviewed the adaptive indicators of stroke volume, left ventricular myocardial thickening, and mitochondrial biogenesis across different interval protocols (such as 4x4 minutes @90% HRmax and 30-second sprints), confirming that short intervals can stimulate cardiovascular remodeling through maximal heart rate stimulation.

Research on the Biomechanical Root Causes of ITBS

Iliotibial Band Syndrome (ITBS) is the most common overuse injury among endurance runners. This mechanical experiment analyzed three-dimensional gait data from 120 runners, and the results revealed that runners with ITBS exhibited significant pelvic lateral tilt during the stance phase. This showed a high positive correlation with gluteus medius weakness and excessive hip adduction angle, directly leading to increased friction between the iliotibial band and the lateral femoral epicondyle.

Comparison of a 12-Week Gluteus Medius Strengthening Program on Pelvic Tilt Angle Improvement in Runners with ITBS

Below is the compiled comparison of the experimental control group and multidimensional data:

Core Research Conclusions and Practical Recommendations

Based on the experimental conclusions of this paper, it is recommended to follow the following arrangements in actual training or equipment selection:

• Quantified Data Monitoring: It is recommended to use heart rate variability or VO2Max zones to continuously assess autonomic nervous system fatigue and overload indicators.
• Hydrodynamic Resistance Reduction: When performing underwater pulls in swimming, focus on engaging the EVF (Early Vertical Forearm) high-elbow catch technique, shifting the fulcrum of force to the latissimus dorsi to prevent rotator cuff overuse injuries.
• Gastrointestinal Adaptation: During long-duration aerobic training, carbohydrate intake per hour should follow the golden ratio of 2:1 glucose to fructose for fueling adaptation.

Common Research Q&A (FAQ)

Q: What should the heart rate target be for interval running?

A: The primary physiological adaptation zone for interval running should be between 90-95% of maximal heart rate (HRmax), or above 95% of maximal oxygen uptake power.

Q: How can carbohydrate tolerance in the digestive tract be improved during long-distance running?

A: This can be achieved by regularly consuming a high proportion of carbohydrates (such as 60-90g/hr) during routine long slow distance (LSD) training sessions to perform “gut adaptation training,” thereby improving the efficiency of intestinal transport proteins.
