Effects of static and dynamic stretching techniques on muscle function

Area of Science:

• Sports Medicine
• Exercise Physiology
• Biomechanics

Background:

• Stretching is commonly used to improve flexibility and potentially enhance muscle function.
• The comparative effects of static stretching (SS) and dynamic stretching (DS) on muscle function remain an area of interest.
• Understanding the impact of different stretching protocols is crucial for optimizing athletic performance and injury prevention.

Purpose of the Study:

• To investigate the effects of combining static stretching (SS) and dynamic stretching (DS) on hamstring muscle function.
• To compare the outcomes of performing SS before DS versus DS before SS.
• To assess changes in flexibility and muscle output following different stretching sequences.

Main Methods:

• Thirty-two healthy male participants were recruited for the study.
• Hamstring flexibility was assessed using the straight leg raise test.
• Muscle output was quantified using a manual muscle force meter.
• Participants were divided into two groups: one performing SS first, followed by DS, and the other performing DS first, followed by SS.

Main Results:

• Both SS and DS significantly improved hamstring flexibility compared to pre-stretching measurements, regardless of the order performed.
• No significant differences were observed in muscle output between the two stretching sequences.
• No significant between-group differences were found for any measured outcome.

Conclusions:

• Both static stretching and dynamic stretching are effective in enhancing hamstring flexibility.
• Neither stretching modality demonstrated a significant impact on muscle output in this cohort.
• The order in which static and dynamic stretching are performed does not appear to influence flexibility or muscle output outcomes.
