Perception of effort, defined as “the conscious sensation of how hard, heavy, and strenuous exercise is” [23, 24], was measured during the incremental test (at the end of each minute) and during the time to exhaustion tests (at the end of the warm-up and every 30 s) using the 15 points RPE scale (Borg 1998). Standardized instructions for the scale were given to each subject before the warm-up. Briefly, subjects were asked to rate how hard they were driving their leg during the exercise (leg RPE [8, 24, 25]). Subjects were also asked to not use this rating as an expression of leg muscle pain (i.e., the intensity of hurt that a subject feels in his quadriceps muscles only).

In recent years, the simple exercise DVD has morphed into a complete “home fitness system,” offering multiple discs with up to a dozen workouts that are combined in very prescriptive ways. They come complete with diets, making them more like plans than just exercise routines. And they cost a lot more than the $10 or $12 you’d spend on a workout DVD. It has been almost a decade since P90X, the leader of the trend, came on the market. The craze shows no sign of slowing down, so we decided to find out whether four leading DVD systems were worth it.
Video Abstract for the ESSR 46.1 article “Sedentary Behaviors and Adiposity in Young People: Causality and Conceptual Model” from author Stuart Biddle. Research on sedentary behavior and adiposity in youth dates back to the 1980s. Sedentary behaviors, usually screen time, can be associated with adiposity. While the association is usually small but significant, the field is complex, and results are dependent on what sedentary behaviors are assessed, and may be mediated and moderated by other behaviors.
When visual inspection gave an indication for group differences, parametric statistical analyses were performed through ANOVA with repeated measures with one withinsubjects factor (post-values for first and second exercise test) and one between-subjects factor (NFO or OTS) or through an independent samples t test. Those analyses were performed in SPSS V.15.0. Sensitivity was also calculated for these variables by dividing the number of correct OTS or NFO diagnoses by hormonal analysis by the total number of OTS or NFO diagnoses according to the consensus statement.1 Sensitivity was presented as a ratio. The denominator varies because of random missing values.
Few interventions exist whereby patients can hope to achieve improvements in both psychiatric symptoms and physical health simultaneously without significant risks of adverse effects. Physical activity offers substantial promise for improving outcomes for people living with mental illness, and the inclusion of physical activity and exercise programs within treatment facilities is warranted given the results of this review.
Thus, little is known about the effects of monitored vigorous exercise in elderly people. While significant benefits for basic motor tasks (such as balance and gait) can be achieved through different kinds of physical activity (i.e., stretching exercises, treadmill, Pilates, and strength and balance training), no conclusive relationship has been proven between its intensity and such improvements. Recently, Pau et al. [14] reported that spatiotemporal gait parameters and sit-to-stand performance significantly improve through vigorous (but not light) exercises, thus suggesting that higher levels of intensity might be more suitable in generally improving static and dynamic daily motor tasks.
