( Schulz, Altman, & Moher, 2010 ). Participants A 6-month, 2-arm parallel group, pilot randomized controlled trial (RCT) was conducted in a co-educational secondary school setting in Sydney, Australia. All girls ( n = 292) from Grades 7–9 (first three years of secondary school, typically ages 12 to 15

Therefore, we hypothesized that HIIT would have better effects than MIACT on gene expression of the cardiovascular biomarker GAL-3 in PMW. Also, we hypothesized that HIIT and MIACT would

The study evaluated the effects of a text message intervention on physical activity in adult working women.
Eightyseven participants were randomized to an intervention (n = 41) or control group (n = 46). Pedometer step counts and measures of self-efficacy were collected at baseline, 12 weeks, and 24 weeks. Intervention participants received approximately 3 text messages per week that were motivational, informational, and specific to performing physical activity.
ANCOVA results showed a significant difference between groups for mean steps per day at 12 weeks (6540.0 vs. 5685.0, P = .01) and no significant difference at 24 weeks (6867.7 vs. 6189.0, P = .06). There was no change in mean step counts during or after the intervention compared with baseline. There was a significant difference between groups for mean self-efficacy scores at 12 weeks (68.5 vs. 60.3, P = .02) and at 24 weeks (67.3 vs. 59.0, P = .03).
Intervention participants had higher step counts after 12 and 24 weeks compared with a control group; however, the difference was significant only at the midpoint of the intervention and was attributable to a decrease in steps for the control group. Text messaging did not increase step counts but may be a cost-effective tool for maintenance of physical activity behavior.

This study examined the effects of an instructed structured Nordic walking (NW) exercise program on the functional capacity of older sedentary people. Volunteers were randomly assigned to an NW group (68.2 ± 3.8 yr old) or control group (69.9 ± 3.0 yr old). Before and at the end of the 9-wk intervention, functional tests and 2-dimensional ground-reaction-force (GRF) patterns of normal (1.40 m/s) and fast (1.94 m/s) walking speeds were measured. The intervention included a 60-min supervised NW session on an inside track twice a week for 9 wk. The mean changes in functional tests differed between groups significantly. Gait analyses showed no significant differences between the groups on any GRF parameters for walking speed either before or after the intervention. The study showed that NW has favorable effects on functional capacity in older people and is a suitable form of exercise for them.
