Comparative effectiveness of social physical play and traditional exercise programming

只有不到十分之一的美国中年成年人达到了推荐量的有氧体育活动(PA)， 极大地增加了他们患心脏病和中风的几率。有超过5000万的成年人在健身 中心会员资格，每月只使用一次，加入新计划后，人们很快就会停止 来了。虽然已经提到了PA的许多障碍(例如，时间、成本)，但我们认为一个关键的、可修改的和 被忽视的障碍是，大多数成年人只是没有足够的体力活动来经常这样做。 研究一致地观察到，更喜欢体育锻炼的人更有可能在 未来。尽管有这种始终如一的观察，但我们并没有意识到有研究提出这样的问题：一个成年的PA 计划旨在最大限度地享受，增加PA的忠诚度和健身能力？“2015年，我们的团队开始了 为成年人设计一个最大限度地享受乐趣的锻炼计划。灵感来自广受欢迎的Pickleball 修改后的网球比赛，我们团队创造了PlayFit。PlayFit是一项成年人参加的锻炼计划 每周三次一起参加一系列运动，所有这些都被修改为1)减少工作量(例如，较小的运动 区域)，2)减少受伤(例如，轻量级低压球)和3)降低竞争力(例如，球队 随机选择，尽量减少身体接触，不记分)。2016年夏季试点工作22 成年人确定了五项修改后的运动，所有这些运动都达到了5.5到6.5的水平，并且满意度很高 (满分为10分，平均得分为8.0分)。更重要的是，这些评论表明，我们已经创造了一种社交的、愉快的 经历：“那真是太有趣了”，“我从来没有踢足球这么开心过”。人们喜欢《笑声》 在比赛中“，”没有压力，没有竞争“，”这不是能力的问题，而是玩得开心。 人“。在这项研究中，我们建议测试与团体相比，PlayFit是否能带来更大的健康收益 健身，以帮助提供商了解的方式帮助提供商和健身中心工作人员了解 我应该推荐锻炼计划来促进长期坚持和健康吗？所有的科目都将是 预计在12个月内每周锻炼三次，每次60分钟。我们将随机分配280名成年人到 两种情况：1)集体健身活动和2)PlayFit。我们假设PlayFit和Group Fitness 在6个月时显著增加V02max，但在12个月后，受更大的享受性和更高的 坚持，随机参加PlayFit的参与者在12个月时比 团体健身。这项研究的结果有可能帮助患者、提供者和健身中心 董事们回答了这个问题：“应该向久坐不动的成年人推荐什么样的锻炼计划？ 为了促进长期坚守和健身吗？

Fewer than 1 in 10 middle-aged US adults get the recommended amount of aerobic physical activity (PA), greatly increasing their chances of heart disease and stroke. There are over 50 million adults with fitness center memberships, which are used only once per month and, after joining new programs, people quickly stop coming. While many barriers to PA have been cited (e.g., time, cost), we believe that a key, modifiable, and underappreciated barrier is that most adults simply do not enjoy physical activity enough to do it regularly. Studies consistently observe that people who enjoy physical activity more are more likely to be more active in the future. Despite this consistent observation, we are not aware of studies that ask “Would an adult PA program designed to maximize enjoyment increase PA adherence and fitness?”. In 2015, our team set out to design an exercise program for adults that maximized enjoyment. Taking inspiration from Pickleball, a popular game of modified tennis, our team created PlayFit. PlayFit is an exercise program in which adults come together three times each week to play a range of sports, all modified to 1) reduce effort (e.g., smaller playing area), 2) reduce injuries (e.g., lightweight low-pressure balls) and 3) reduce competitiveness (e.g., teams chosen randomly, minimize physical contact, no keeping score). Pilot work in the summer of 2016 with 22 adults identified five modified sports that all had MET levels between 5.5 and 6.5 and high satisfaction scores (average of 8.0 out of 10). More importantly, the comments suggest that we have created a social, enjoyable experience: “that was SO much fun”, “I’ve never had so much fun playing soccer”. People liked “the laughter during the games”, “no pressure, not competitive” and that “it’s not about ability, it’s just about having fun with people”. In this study, we propose testing whether PlayFit leads to greater fitness gains, compared to group fitness, to help providers understand in a way that helps providers and fitness center staff understand: “What exercise program should I recommend to promote long-term adherence and fitness?”. All subjects will be expected to exercise three-times weekly for 60 minutes for 12 months. We will randomly assign 280 adults to two conditions: 1) Group Fitness activities and 2) PlayFit. We hypothesize that both PlayFit and Group Fitness will increase V02max significantly at 6 months but, after 12 months, mediated by greater enjoyment and higher adherence, participants randomized to PlayFit will have greater fitness and activity gains at 12 months than Group Fitness. The results of this study have the potential to help patients, providers and fitness center directors by answering the question: “What exercise program should be recommended to sedentary adults in order to promote long-term adherence and fitness?"
