We investigated cross-cultural differences in ninth-grade students’ reported use of self-regulated strategies for writing. We assessed 12 self-regulated strategies for writing tapping environmental, behavioural, and personal self-regulated processes. Seven hundred and thirty-two Portuguese and Brazilian students in transition to high school (Mage = 14.3; 372 male and 306 female) from mainstream urban schools reported on their use of the strategies. Statistical analyses included a multivariate analysis of variance (MANOVA) with 12 dependent variables (self-regulated strategies for writing) and 2 between-subjects variables (country and gender). There were significant main effects for country with medium effect sizes and statistically significant small effect sizes for gender main effects. All-male and all-female comparisons indicated significant differences and medium effect sizes within gender groups. The majority of the differences tapped personal self-regulated strategies. Taken together, these findings suggest that initiating and controlling writing may be a contextualised bounded process.

The aim of this study was to compare the cardiovascular and perceived effort of head‐out water exercises selecting different limb strategies and using resistance equipment. Ten young women were randomly assigned to perform at 132 bpm during five minutes different head‐out aquatic exercises: (i) horizontal arms abduction (Ab); (ii) horizontal arms abduction with dumbbells (AbD); (iii) frontal kick (Fk); (iv) frontal kick with leggings (FkLeg), and; (v) aquatic skiing (Ski). Cardiovascular effort was measured by monitoring the heart rate, blood pressure and double product. Perceived effort was assessed by the Borg’s scale. Within‐routines comparison was computed using repeated‐ measures ANOVA followed‐up by the Bonferroni post‐hoc test. Considering the percentage of the maximal heart rate, participants reached 72.88 ± 12.90% in the FkLeg, 65.99 ± 10.91% in the Fk, 62.62 ± 7.20% in Ski, 57.27 ± 11.58% in AbD and 57.12 ± 12.09% in Ab. Comparing exercises, higher heart rates were observed in the FkLeg (140.40 bpm) than Ab (110.30 bpm) or AbD (110.00 bpm). Significant differences were found in the systolic blood pressure when compared to the Fk (120.60 mmHg) and Ab (104.50 mmHg). Double product was higher in the FkLeg (16990) showing a meaningful difference when compared to Ab (11608) or AbD (12001). The highest perceived effort was found in the FkLeg (15.80) with meaningful variations compared to Ab (11.70), the Fk (13.70) and Ski (10.40). Thus, different head‐ out water exercises result in different intensities. The actions by lower limbs promote a higher cardiovascular response, whereas the upper limbs actions trigger a lower exertion. Moreover, exercising the four limbs concurrently seems to be less intense than using only two limbs with an aid.
