The number of Masters Athletes competing worldwide has increased, yet little research on the health and lifestyle behaviors of Masters Athletes participating in team sports has been undertaken. PURPOSE: The purpose of this study was to examine the health and lifestyle behaviors of international Masters Field Hockey Athletes competing in the Masters Field Hockey World Cup in Barcelona, Spain in 2018. METHODS: Participants were 488 athletes (301 women, 186 men) from 26 countries, 35 to 76 years of age (51.4±7.9 years). Participants completed the 42-item Health and Wellbeing of Master’s Field Hockey Athletes Survey, which asked about demographics, health status, and lifestyle behaviors. RESULTS: Mean body mass index was 24.2±2.9 kg/m² (range = 15.2 to 35.3 kg/m²). Participants rated their health as “very good” or “excellent” (86.9%), had no major health conditions (64.8%), medication use (84.2%), or injuries (51.0%). Perceived stress was rated as “rare” or “not at all” by 57.9% of participants. Participants consumed ≥2 fruits (65.3%) and ≥2 vegetables per day (78.3%), daily breakfast (68%), ≤1 sugar-sweetened beverage (80.1%) per day, ≥7 cups of water (43.0%) per day, and ≤2 alcoholic beverages per week (54.9%). Only 5.3% of participants reported using tobacco products. Participants reported ≥7 hours of sleep per night (68.4%), with no or little restless sleep (48.0%). Just under half of participants reported sitting ≥5 hours per day (45.3%). Exercise frequency at ≥3 days per week and ≥30 minutes per session was cited by 92.9% and 93.5% of the sample, respectively. Aside from field hockey, predominant activities included: jogging (62.9%), walking (56.1%), high intensity training (41.4%), and cycling (29.7%). CONCLUSION: While there are areas for improvement, Masters Field Hockey Athletes generally practice lifestyle behaviors conducive to positive health.
