This study aimed at answering the question: do people with high bone loss have greater postural instability? Groups were separated into group 1: women with normal bone mineral density, group 2: women with osteopenia, and group 3: women with osteoporosis. The balance was evaluated in four upright postural situations. Osteoporosis group had greater oscillation in the anteroposterior displacement in all situations compared to control group and the greatest mediolateral displacement in all situations compared to other groups. Introduction It is not known whether the presence of osteoporosis can be considered a factor aggravating the postural control. This study aimed at answering the question: do people with high bone loss have greater postural instability? Methods This study was divided into three groups: group 1 (n=20) consisting of women with normal bone mineral density, group 2 (n=20) women with osteopenia, and group 3 (n=20) women with osteoporosis. All the participants were submitted to evaluation of the balance using the Polhemus system in four upright postural situations. Results Osteoporosis group had greater oscillation in the anteroposterior displacement in all situations compared to control group. The osteoporosis group also showed the greatest mediolateral displacement in all situations compared to other groups. Conclusion The results suggest that osteoporotic women had the worst balance, possibly due to the more pronounced body changes compared to non-osteoporotic women.

Background: Walking speed seems to be related to aerobic capacity, lower limb strength, and functional mobility, however it is not clear

Purpose This study compared the acute effects of an exergame-based calisthenics (EXG) session versus a traditional calisthenics (TC) session on state anxiety levels in healthy adult men, and compared the mean heart rate, number of repetitions performed, enjoyment, and affective valence reported by the participants between sessions. Methods Thirty-six young adult men performed two 30-min sessions of physical exercise in random order (EXG and TC). The same exercise protocol was used for each session; however, the TC session was guided by an exercise science professional. State anxiety was assessed before and immediately after each session. Heart rate was monitored during the sessions. Enjoyment and affective valence were assessed immediately after the sessions. In addition, the number of repetitions performed was recorded. Results There was no significant interaction between sessions (EXG vs. TC) and time (pre vs. post-session) ( p = 0.102), no significant effect of session ( p = 0.587), and no significant effect of time ( p = 0.121). Participants presented a higher mean heart rate (+ 3.5%, p = 0.020) and number of repetitions performed (+ 43.7%, p < 0.001) in the TC session compared with the EXG session. There was no difference in enjoyment ( p = 0.804) and affective ( p = 0.195) valence between the EXG and TC sessions. Conclusion The EXG and TC sessions did not reduce state anxiety levels. Nor did they increase enjoyment or affective valence in healthy young adult men. However, the TC session evoked a higher mean heart rate and higher training volume than the EXG session.
