# The Effects of Intermittent Hypoxic Training on Anaerobic Performance in Young Men
## 3 Results  
The groups did not differ (f = 0.13, \(p\) = 0.88, \(\mathrm{\eta p^{2}}\) = 0.005) in self-declared physical activity, which was 6376.5 \(\pm\) 1881.3 MET-min/week (IHT), 6154.9 \(\pm\) 2509.5 MET-min/week (NT) and 6582.7 \(\pm\) 2831.0 MET-min/week (ctrl). Participants did not differ significantly (f = 0.16, \(p\) = 0.85, \(\mathrm{\eta p^{2}}\) = 0.01) in weekly caloric intake (IHT: 20,707 \(\pm\) 3656 kcal/week, NT: 21,233 \(\pm\) 3352 kcal/week, ctrl: 21,291 \(\pm\) 2434 kcal/week). Participants did not differ significantly in body composition (Table 1). Moreover, neither body mass nor body composition changed significantly after the training intervention (Table 1, [27]). \begin{table}
