Numerous mobile apps available for download are geared toward health and fitness; however, limited research has evaluated the real-world effectiveness of such apps. The movr app is a mobile health app designed to enhance physical functioning by prescribing functional movement training based on individualized movement assessments. The influence of the movr app on functional movement and physical fitness (flexibility, strength, and cardiovascular fitness) has not yet been established empirically.
This study aims to examine the real-world impact of the movr app on functional movement, flexibility, strength, and cardiovascular fitness.
A total of 48 healthy adults (24 women and 24 men; mean age 24, SD 5 years) completed an 8-week pilot pragmatic randomized controlled trial in which they were randomly assigned to either 8-week use of the movr app (n=24) or 8-week waitlist control (n=24). Measures of functional movement (Functional Movement Screen [FMS]), strength (push-ups, handgrip strength, and countermovement jump), flexibility (shoulder flexibility, sit and reach, active straight leg raise [ASLR], and half-kneeling dorsiflexion), and cardiovascular fitness (maximal oxygen uptake []) were collected at baseline and the 8-week follow-up.
Repeated measures analyses of variance revealed significant group-by-time interactions for the 100-point FMS (P<.001), shoulder flexibility (P=.01), ASLR (P=.001), half-kneeling dorsiflexion (P<.001), and push-up tests (P=.03). Pairwise comparisons showed that FMS scores increased from pre- to postintervention for those in the movr group (P<.001) and significantly decreased for those in the control group (P=.04). For shoulder flexibility, ASLR, half-kneeling dorsiflexion, and push-up tests, improvements from pre- to postintervention were found in the movr group (all values of P<.05) but not in the control group (all values of P>.05). There were no changes in the sit and reach or handgrip strength test scores for either group (all values of P>.05). A significant main effect of time was found for the countermovement jump (P=.02), such that scores decreased from pre- to postintervention in the control group (P=.02) but not in the movr group (P=.38). Finally, a significant group-by-time interaction was found for (P=.001), revealing that scores decreased pre- to postintervention in the control group (P<.001), but not in the movr group (P=.54).
The findings revealed that movr improved indices of functional movement (FMS), flexibility (shoulder, ASLR, and dorsiflexion), and muscular endurance (push-ups) over an 8-week period compared with the control group while maintaining handgrip strength, lower body power (countermovement jump), and cardiovascular fitness (). Thus, this study provides initial evidence of the effectiveness of the movr app for enhancing functional movement and physical fitness among healthy adults.

市场上有许多可下载的移动应用程序，旨在促进健康和健身；然而，有限的研究评估了这些应用程序在现实世界中的实际效果。movr 应用程序是一款移动健康应用程序，旨在通过基于个性化运动评估的功能运动训练来提高身体机能。movr 应用程序对功能运动和身体健康（灵活性、力量和心血管健康）的影响尚未得到实证研究的证实。
本研究旨在检验 movr 应用程序对功能运动、灵活性、力量和心血管健康的实际影响。
共有 48 名健康成年人（24 名女性和 24 名男性；平均年龄 24 岁，标准差 5 岁）完成了一项为期 8 周的实用随机对照试验的试点研究，他们被随机分为 8 周使用 movr 应用程序组（n=24）或 8 周候补对照组（n=24）。在基线和 8 周随访时，测量功能运动（功能运动筛查 [FMS]）、力量（俯卧撑、握力和深蹲跳）、灵活性（肩部灵活性、坐立和伸手、主动直腿抬高[ASLR]和半跪位背屈）和心血管健康（最大摄氧量[VO2max]）。
重复测量方差分析显示，100 分 FMS（P<.001）、肩部灵活性（P=.01）、ASLR（P=.001）、半跪位背屈（P<.001）和俯卧撑测试（P=.03）的组间时间交互作用显著。两两比较显示，movr 组 FMS 评分从干预前到干预后均增加（P<.001），对照组评分显著降低（P=.04）。对于肩部灵活性、ASLR、半跪位背屈和俯卧撑测试，movr 组在干预前到干预后的评分都有所提高（所有 P 值均<.05），但对照组则没有（所有 P 值均>.05）。两组的坐立和伸手或握力测试评分均无变化（所有 P 值均>.05）。对照组的深蹲跳评分有显著的时间主效应（P=.02），从干预前到干预后评分均下降（P=.02），但 movr 组则没有（P=.38）。最后，发现（P=.001）的组间时间交互作用显著，表明对照组的评分从干预前到干预后下降（P<.001），而 movr 组则没有（P=.54）。
与对照组相比，movr 在 8 周内提高了功能运动（FMS）、灵活性（肩部、ASLR 和背屈）和肌肉耐力（俯卧撑）的指标，同时保持了握力、下肢力量（深蹲跳）和心血管健康（VO2max）。因此，本研究初步证明了 movr 应用程序在提高健康成年人的功能运动和身体健康方面的有效性。
