دراسة تظهر ما يمكن أن تفعل 10 دقائق فقط من الجري بدماغك!
كشفت دراسة جديدة أن ممارسة الجري معتدل الشدة لمدة 10 دقائق كافية لتعزيز مزاجك ووظائفك الإدراكية، وهي النتائج التي تمنحنا فهما أفضل لكيفية ارتباط التمارين البدنية بالصحة العقلية.
ونظرت الدراسة في قشرة الفص الجبهي (PFC) على وجه الخصوص، وهي الجزء من الدماغ المرتبط بالوظائف التنفيذية والتحكم في المزاج. واكتشف الباحثون أن الجري أدى إلى زيادة تدفق الدم في هذه المنطقة.
ويعد الجري أمرا يسهل على الكثيرين منا القيام به نسبيا – لا يلزم وجود معدات خاصة أو تدريب للبدء، وثبت أنه يطيل العمر الافتراضي. ويبدو أن كل هذه الحركة المنسقة تمنح الدماغ أيضا المزيد من التفكير فيه.
ويقول عالم الكيمياء الحيوية هيدياكي صويا، من جامعة تسوكوبا في اليابان: “نظرا لمدى التحكم التنفيذي المطلوب في تنسيق التوازن والحركة والدفع أثناء الجري، فمن المنطقي أن يكون هناك تنشيط عصبي متزايد في قشرة الفص الجبهي وأن الوظائف الأخرى في هذه المنطقة ستستفيد من هذه الزيادة في موارد الدماغ”.
نحن نعلم بالفعل أن التمرينات يمكن أن تعزز الصحة العقلية والبدنية بعدة طرق، ولكن عندما يتعلق الأمر بالصحة العقلية، كان هناك القليل نسبيا من التحليل الذي أجري حول الفوائد المحددة للركض، مقارنة بالأنشطة البدنية الأخرى مثل ركوب الدراجات.
وكان هذا شيئا قرر الباحثون معالجته، مع الأخذ في الاعتبار مدى أهمية الجري لتطورنا كنوع.
واختبر ما مجموعه 26 مشاركا بعد فترات من الراحة وبعد 10 دقائق من الجري، جزئيا باستخدام ما يُعرف باسم اختبار Stroop Color-Word الذي يقيس أوقات رد الفعل في معالجة الدماغ – قد يتضمن أحد التمارين رؤية كلمة “أخضر” مكتوب بالحبر الأحمر وعليك تسمية اللون بدلا من قراءة الكلمة.
وبعد التمرين، كان المشاركون يتفاعلون بسرعة أكبر مع الاختبارات وأفادوا أنهم في حالة مزاجية أفضل أيضا. وكان ذلك بالإضافة إلى زيادة تدفق الدم الذي لوحظ في PFC باستخدام تقنية تسمى التحليل الطيفي للأشعة تحت الحمراء الوظيفية (fNIRS).
وهناك الكثير من وظائف PFC الفريدة من نوعها بالنسبة للبشر، ولا توجد في أدمغة الحيوانات الأخرى، لذلك يقترح الباحثون أن الاكتشافات التي أوجزوها يمكن أن تزيد من فهمنا لكيفية تطورنا كنوع أيضا. إنه أيضا دليل آخر على أنك لست بحاجة بالضرورة إلى ممارسة الكثير من التمارين لتشعر بفوائدها. وسبق أن ثبت أن الاندفاعات القصيرة من النشاط تعمل على تحسين التركيز العقلي وصحة القلب وصحة التمثيل الغذائي بشكل عام.
ويشير الباحثون إلى أنه إذا كان من الممكن اعتبار التمرين شكلا من أشكال الطب، فإن الأنواع المختلفة من التمارين تشبه أنواعا مختلفة من الأدوية – ونحن الآن نعرف المزيد عن تأثيرات الجري وكيف يمكن استخدامه كشكل من أشكال العلاج.
