Few studies have examined the relationship between changes in hand volume and typing. Volumetric evaluation documents the presence of an inflammatory response to activity.
To study this relationship, researchers used a convenience sample of 31 participants who were aged 45 and older and worked full time where they typed at least one hour per day. Volumetric measurements were taken before a 15-minute typing activity, immediately after and 10 minutes after typing. Before typing, ergonomic adjustments were made to computer workstations, when necessary. Participants typed using an advanced speed test of the Mavis Beacon Teaches Typing program, which calculated adjusted words per minute.
The data showed no significant (F = 0.321, p > 0.05) change in hand volume resulting from the typing activity.
The amount of exercise provided in this study, a fifteen minute typing activity, did not result in changed hand volume.
很少有研究探讨手部体积变化与打字之间的关系。容积评估记录了对活动的炎症反应的存在。
为研究这种关系,研究人员使用了一个便利样本,其中包括31名年龄在45岁及以上、全职工作且每天打字至少一小时的参与者。在15分钟打字活动前、活动刚结束后以及结束后10分钟进行容积测量。打字前,必要时对计算机工作站进行了人体工程学调整。参与者使用Mavis Beacon Teaches Typing程序的高级速度测试进行打字,该测试计算每分钟调整后的字数。
数据显示,打字活动导致的手部体积没有显著变化(F = 0.321,p > 0.05)。
本研究中提供的运动量,即15分钟的打字活动,并未导致手部体积改变。
