久坐不起是造成現代人肥胖的一個主因,而研究發現採用運動計畫減重容易讓人放棄。因而有人提倡"非體育性運動"(Non-Exercise Activity Thermogenesis, NEAT)如走路,爬樓梯等活動。藉由改變生活習慣來增加NEAT活動。而前人的文獻中，大多將遊戲與走路(最普遍存在生活中的NEAT)來做結合,但是發現運動意願低者卻不受遊戲鼓勵而增加走路量;並且以往的研究都著重於"遊戲本身"對於人運動的鼓勵，而不是人與人之間的人際互動行為研究。
本研究將重點放在透過團隊間的鼓勵，激發運動意願低者增加步行活動。在實驗中，兩隊各四個人的隊伍間，用走路步數轉換來的活動點數競爭商家禮卷，點數投入多的隊伍成員會獲得該店家禮卷。每個隊伍有運動意願高及意願低的參加者各兩名；目的在於讓意願高者鼓勵意願低者增加運動。經過活動後，發現運動意願低者確實能被同隊的使用者鼓勵，增加步行量並改變生活習慣，以及提升走路意願。

Sedentary lifestyle is a main cause of obesity, and accompany with chronic diseases. Some medical research shows NEAT(Non-Exercise Activity Thermogenesis) is a potential way to decrease obesity problem, that people could exercise in everywhere and anytime. To encourage people to increase physical activity in daily lives, we design an activity to promote people walk more. This activity is competed in teams by everyday foot counts of team members.
This paper focus on encouraging people with low willingness to increase physical activities by group encouragement that other research shows those people are hard to be influenced by application only. In my research, people with low willingness and high willingness were grouped to two teams; each team was composed of active and inactive users in same population (2 active, and 2 inactive in each team). All the participants wear pedometers to calculate everyday foot counts and convert it to activity points by uploading to a web-based platform where activity took place. In the activity, participants invest their “sport points” to win store coupons as reward, then the team which invested more points win the store coupons. After a six weeks experiment, users with low willingness performed more walk than before and expressed they are encouraged by team members. Furthermore, they changed their daily habits to walk more and improved their walking attitude.
