Stretch-Induced Reductions in Throwing Performance Are Attenuated by Warm-up Before Exercise.

Area of Science:

• Sports Science
• Exercise Physiology
• Biomechanics

Background:

• Static stretching (SS) performed before exercise has been linked to reduced muscular performance.
• The potential mitigating effects of dynamic warm-up exercises when combined with SS remain unclear.
• Understanding pre-exercise routines is crucial for optimizing athletic performance and preventing injury.

Purpose of the Study:

• To investigate the acute effects of static shoulder stretching (SS) versus dynamic warm-up exercises, or a combination of both, on upper limb muscular performance.
• To evaluate the impact of different pre-exercise protocols on medicine ball throwing distance and handball ball throwing speed.

Main Methods:

• Twenty-one female handball players participated in the study.
• Participants performed static stretching, dynamic warm-up exercises, or a combination of both, targeting upper limb muscles.
• Muscular performance was assessed using medicine ball throwing distance and handball ball throwing speed tests.

Main Results:

• Static stretching alone significantly reduced medicine ball throwing distance compared to dynamic warm-up exercises.
• Combining static stretching with dynamic warm-up exercises abolished the detrimental effects of SS on throwing distance.
• Throwing speed remained consistent across all three pre-exercise conditions (SS, dynamic warm-up, combined).

Conclusions:

• Dynamic warm-up exercises effectively counteract the negative impact of static stretching on throwing distance.
• Athletes are advised to incorporate dynamic warm-up exercises alongside static stretching before physical activity.
• This combined approach can help prevent acute reductions in muscle strength and performance.
