Recent studies have estimated the prevalence of depression during pregnancy to be between 10% and 30%, which is higher than that in the postpartum period. Pharmacological treatment during pregnancy is difficult because of the possible side effects of antidepressants on the mother and the fetus. The aim of this study was to examine whether a supervised exercise program (EP) reduces depressive symptoms in pregnant women. A randomized controlled trial was designed. One hundred eighty four healthy pregnant women from Fuenlabrada Hospital were included (31.37 ± 3.62 years). Women from the exercise group (EG) participated in a supervised EP consisting of three, 55- to 60-min sessions per week throughout pregnancy. The main outcome measure was the patients' depression level assessed by means of the Center for Epidemiologic Studies Depression Scale (CES-D). A total of 167 pregnant women were analyzed; 90 were allocated to the EG and 77 to the control group (CG). Significant differences were found between groups at the end of the study in CES-D scores (EG: 7.67 ± 6.30 vs. CG: 11.34 ± 9.74, p = .005) and in percentages of pregnant women depressed (EG: n = 11/12.2% vs. CG: n = 19/24.7%, p = .04). Our results show that supervised physical exercise during pregnancy reduces the level of depression and its incidence in pregnant women. APA reference to the study: Perales, M., Refoyo, I., Coteron, J., Bacchi, M., & Barakat, R. (2015). Exercise during pregnancy attenuates prenatal depression: a randomized controlled trial. Evaluation & the Health Professions, 38(1), 59-72. Question: What is the effect size (Cohen's d) of exercise on depressive symptoms based on the post-test CES-D scores? Calculate a simplified pooled standard deviation by averaging the EG and CG standard deviations (6.30 and 9.74, respectively). Provide the effect size with two decimals 0.46 and interpret its strength medium (pick the best answer option).

The lactate threshold occurs due to the rate of appearance being greater than the rate of removal

True

The relative risk of all cause mortality may be up to 3 times higher in men with the lowest CRF compared to men with the highest CRF.

True

When looking at data related to people meeting the current PA recommendations, a study by the NIH called the American Association of Retired Persons Diet and Health Study gave us evidence that even those who are physically active but below the minimum recommendations (insufficiently active) saw a decrease in mortality rates as compared to those who reported No activity

True

Vocabulary

The following table is from a large cohort study about the effects of physical activity and body mass index on cardiovascular, cancer and all-cause mortality among middle-aged Finnish men and women. Based on the table, do men or women seem to benefit more from high physical activity levels when it comes to cardiovascular mortality? Note: Use the hazard ratios from Model 1 for men and women.

The meta-analysis referenced below (Oberlin et al., 2017) sought to determine the effect of exercise on cognitive function in people who had a stroke. Based on the 95% confidence interval (95% CI) for the overall effect (ES total) of exercise on cognitive performance, is the effect of exercise on cognitive performance statistically significant?

Yes

How strong is the effect of regular exercise on resting brain-derived neurotrophic factor (BDNF) levels based on the referenced study below? Note: Hedges' g can be interpreted the same way as a Cohen's d. The answer to this question can be found in the abstract of the study. APA reference to the study: Szuhany, K. L., Bugatti, M., & Otto, M. W. (2015). A meta-analytic review of the effects of exercise on brain-derived neurotrophic factor. Journal of Psychiatric Research, 60, 56-64.

According to Mason et al. (1992) vigorous exercise at least once per week can lower the risk of Type II diabetes by 29%

true

true

Risk of all-cause mortality is reduced by about 30% in those with muscular strength in the upper tertile compared to those in the lower tertile

true

Sudden cardiac death is due to abnormal electrical activity of the heart whereas heart attacks are due to myocardial ischemia due to cardiovascular disease

true

The Mechanostat theory indicates that bone cells increase bone tissue formation in response to mechanical stress

true

The dependent/outcome variable is displayed on the y-axis in most graphs

true

The resistance training recommendations for novice lifters specify 2-3 times per week, 60-70% of 1 RM and exercises that target all major muscle groups

true

The following table is from a large cohort study about the effects of physical activity and body mass index on cardiovascular, cancer and all-cause mortality among middle-aged Finnish men and women. Based on the table, do men or women seem to benefit more from moderate physical activity levels when it comes to cardiovascular mortality? Note: Use the hazard ratios from Model 1 for men and women.
