Background: The main purpose of this research was to determine the stability of three different sanitary shoes on nurses with eyes open and closed with respect to barefoot condition. In addition, the secondary aim was to determine the reliability of stability measurements under these different conditions. Methods: A crossover quasi-experimental study (NCT03764332) was performed. Twenty-six nurses who wore different sanitary shoes (Eva Plus Ultralight®, Gym Step® and Milan-SCL Liso®) were evaluated with respect to barefoot condition for stability measures on the Podoprint® podobarometric and stabilometry tool and with eyes open and closed. Furthermore, the reliability of stability measurements was determined by the intraclass correlation coefficient (ICC) under these different conditions. Results: Between-groups comparisons of the static and stabilometry podobarometric data with eyes open showed statistically significant differences (p < 0.05). Milan-SCL Liso® sanitary shoes improved podobarometric data of forefoot force and distribution with respect to barefoot condition. Eva Plus Ultralight® and Gym Step® sanitary shoes increased the stroke length mean, stroke surface mean, and anterior speed mean as well as reduced y axis displacement mean with respect to barefoot condition. Similar findings were determined for measurements with eyes closed. ICCs ranged from poor to excellent reliability (ICC = 0.010–0.995). Conclusions: Sanitary shoes improved podobarometric and stabilometry stability with respect to barefoot condition.

COVID-19-induced quarantine may lead to deleterious effects on health status as well as to impaired performance and increased injury risk when re-starting training after lockdown. We investigated the physical activity (PA) habits of recreational runners in Spain during a 48-day home quarantine during the COVID-19 pandemic and the characteristics of the first outdoor running session after confinement. A cross-sectional study, including a self-reported running questionnaire completed after the first outdoor running session after quarantine, was performed. Three hundred recreational runners (74% males; 60% 18–40 years old; most typical running experience >3 years, 10–30 km weekly running distance distributed in 3–4 sessions) were considered for analysis. Advanced runners ran, at least, 4 days/week and participated in running events. They performed significantly longer and more non-supervised weekly training sessions during confinement (p < 0.01 for both) than novice and amateur runners. Most runners performed their first outdoor running session on asphalt (65.3%) and ran 5 to 10 km (61%) at a pace above 5 min/km (60%), reporting no pain before (77%), during (64%), and 24 h after (76%) the session. Advanced runners performed a significantly longer running session, at a higher pace, and covered a greater distance (p < 0.01 for all) than novice and amateur runners, while enjoyment and motivation tended to be significantly higher when runners’ level increased (p < 0.05). Higher training levels prior to and during confinement may lower the collateral effects (e.g., detraining, injury risk) of home quarantine when runners return to previous PA levels.
