Secara alami kita akan menggerakan tangan saat berlari, hal ini dilakukan agar seimbang ketika berlari. Namun masih belum diketahui apakah mengayunkan tangan akan memboroskan energi ketika berlari. Hal inilah yang menjadi pusat perhatian bagi peneliti di Brown University.
Dalam studi terbaru, peneliti menganalisa orang yang rutin berlari, baik untuk rekreasi ataupun yang berkompetisi. Mereka diminta untuk berlari secara normal di trealmill, sementara peneliti mengkur kelajuan oksigen yang dihirup dan karbohidrat yang dikeluarkan.
Penelitiannya tidak sampai disitu, peserta juga diminta untuk berlari tanpa mengayunkan lengan dengan tiga cara. Group pertama merekatkan kedua tangan di punggung, goup kedua menyilangkan tangan di dada, dan group terakhir menaruh tangan di atas kepala.
Bagaimana hasilnya? Setelah dilakukan penelitian, studi pun menemukan bahwa orang yang berlari dengan mengayunkan lengan rupanya lebih boros tenaga 3 persen daripada yang tangan mereka dipungung, 9 persen lebih bros dengan menyilangkan tangan di dada dan 13 persen lebih boros dengan menaruh tangan di kepala.
Walaupun hasilnya menyimpulkan bahwa menyaunkan lengan lebih banyak makan energi dibanding yang tidak, namun apabila tidak dilakukan, pelari dapat menghabiskan energi total yang jauh lebih banyak. Alasan ini pun diungkapkan peneliti, menganyunkan lengan akan mengurangi gerakan torso. Padahal massa torso mencapai 40-50 persen massa tubuh, sedangkan massa lengan hanya 10 persennya.
Jadi intinya, Anda bisa mengayunkan lengan namun tidak terlalu berlebihan. Ayunkan lengan untuk membantu keseimbangan dan meringkan massa torso yang dibebankan ketika berlari itu adalah rahasia besar anti lelah saat berlari.
