“…There was relatively little difference, however, in the average temperature and rainfall over this period (December temperature = 6.9 °C, rainfall = 64 mm; April temperature = 9.6 °C, rainfall = 74 mm). Furthermore, recent work conducted by Ridgers et al (23) in schools from the same city and socioeconomic background as those in our study found that there were no significant differences in the day-today and season-to-season variability of children's PA during recess. On this basis they suggested that there might be no need to correct for seasonal differences in PA during recess, which was the period of time when we hypothesized that most PA would occur.…”

“…In the first session, participants had their height (cm) and body mass (kg) assessed using a Seca Stadiometre and weighing scales (Seca Instruments, Frankfurt, Germany) and were fitted with a heart rate monitor (RS400, Polar Electro, Kuopio, Finland). Resting heart rate was recorded for 5 minutes in a supine position following procedures previously described (Ridgers, Stratton, Clark, Fairclough & Richardson, 2006). This data was used to determine exercise intensities of 50% (moderate) and 75% (vigorous) of maximal heart rate reserve (Karvonen & Vuorimaa, 1988) to be used in subsequent experimental sessions.…”

“…Recognising that the use of maximal heart rate as an indicator of exercise intensity fails to account for individual differences in fitness level, maximal heart rate reserve was employed in the present study. Moreover, intensities of 50% and 75% heart rate reserve were chosen as these intensities directly relate to moderate to vigorous physical activity, the recommended intensity of physical activity for health benefit in children (Ridgers et al, 2006).…”

“…Recess provides a break from classroom time and promotes learning behaviours, problem-solving skills, and learning readiness 5,11,12 Recess also offers children the opportunity to engage in physical activity on a daily basis. 13 In the United Kingdom, recess is mandatory and can account for up to 25% of the school day. 14 .…”
