Abstract	BACKGROUND: The aim of this study was to compare the effect of the intermittent and traditional physical fitness-based teaching units on cardiorespiratory fitness and physical activity levels in high school students during Physical Education sessions. METHODS: One hundred and three high school students (Mage=13.6± 0.7) from six classes, balanced by grade, were cluster-randomly assigned into traditional (TG), intermittent (IG), and control (CG) groups. The TG performed a fitness teaching unit twice a week for nine weeks (35-40 minutes of the main part of each session). The IG worked during the first half of the sessions' main part (18-20 minutes) similarly to the TG, and during the second half they worked on technical-tactical aspects of invasion sports. Students' cardiorespiratory fitness was measured at the beginning and at the end of the teaching unit. Physical activity levels were measured objectively through a heart rate monitor and subjectively by a self-reported scale during Physical Education sessions. RESULTS: Both traditional and intermittent teaching units developed students' cardiorespiratory fitness levels (Delta post-pre-intervention: TG, M Delta=19.8, SE=9.4; IG, M Delta=16.6, SE=7.7); P(0.01). Additionally, both TG (M=86.2, SE=9.9) and IG (M=90.9, SE=7.6) had higher physical activity levels than the CG (M=76.3, SE=13.5) (P(0.05). However, no differences in physical activity levels were found between the IG and TG (P)0.05). CONCLUSIONS: The intermittent teaching unit allowed the simultaneous development of cardiorespiratory fitness and another curricular objective in the same Physical Education sessions. (Autor).
