Comparing the effect of individual and group cognitive-motor training on reconstructing subjective well-being and quality of life in older males, recovered from the COVID-19.

While the message emanating from physiological and psychological research has extolled the general advantages of exercise in physical and cognitive health, the social distancing and the impossibility of group exercises have revealed more complex conditions. Therefore, we performed an experimental study comparing the effect of individual and group cognitive-motor training on reconstructing subjective well-being (SWB) and quality of life (QOL) in older males who recovered from COVID-19. The study's design is a single-blind, randomized controlled trial (RCT). The participants, 36 older men (65-80 yrs.) recovering from COVID-19, were randomly divided into (1) Group A (cognitive-motor training, G-CMT); (2) Group B (individual cognitive-motor training, I-CMT); and (3) Group C (control). Both training interventions involved performing a training protocol (cognitive-motor training) twice a week for four weeks. The outcomes included an assessment of the SWB and QOL of participants by SWB scale and world health organization QOL scale at baseline and two weeks after interventions. Except for the effect of age and number of children variables on QOL, other demographic variables had no significant effect on the results of SWB or WHOQOL of participants (P > 0.05). The SWB results in G-CMT were better than I-CMT and control groups in emotional and social well-being domains. Also, WHOQOL test results in G-CMT were better than control groups in domains of psychological and social relationships, whereas I-CMT performed better than G-CMT and control groups in domains of cognitive well-being, physical health, and environment. The results revealed that the mean test scores of SWB and WHOQOL in G-CMT and I-CMT were better than the control group (P ≤ 0.001). The positive effects of cognitive-motor training on reconstructing SWB and QOL are associated with the synchronicity of cognitive and motor components in these exercises. We suggest that the emotional, social, and psychological benefits of cognitive-motor training override cognitive, physical, and environmental changes. The future line of the present study will include pathophysiology and further clinical aspect of recovering from COVID-19.

The effectiveness of cognitive-motor training on reconstructing cognitive health components in older male adults, recovered from the COVID-19.

OBJECTIVE: The incidence of COVID-19 disease in the elderly can accelerate normal degenerative process of cognitive functions. Interactive cognitive-motor training (CMT) is an intervention that integrates cognitive and motor tasks to promote individuals' physical and psychological health. The present study aimed to examine the effect of CMT on reconstructing cognitive health components in older men, who have recently recovered from COVID-19. MATERIALS AND METHODS: This study is a quasi-experimental repeated measure (without control group). Participants were 42 elderly men (65-80 years) who recovered from the COVID-19 disease that individually participated in a 4-week CMT program twice a week. The cognitive health components of the participants were assessed by the General Health Questionnaire (GHQ-2) and the Mini-Mental State Examination (MMSE) at 3 stages before the beginning of the intervention (baseline assessment); 2 weeks after the intervention (short-term follow-up); and 3 months after the intervention (long-term follow-up). RESULTS: The results showed that the scores of depression, anxiety, physical symptoms, and social performance components and the overall GHQ score improved significantly in short-term follow-up (P < 0.05) and also in long-term follow-up compared to baseline assessment (P < 0.05). It was also found that attention and calculation, recall, lingual skill, and action performance components and the overall score of MMSE were also improved at three stages of assessments. Other components did not differ among stages. CONCLUSIONS: This study adds to the research on the effectiveness of using CMT for reconstructing cognitive health components in older adults, recovered from the COVID-19, and supports CMT as a viable intervention practice.

The Effect of Differential Attentional Focus Strategies on the Performance of Military Elite Shooters.

METHODS: This study is semiexperimental with an intragroup design. A number of 10 military marksmen (30-42 years old) with at least 10 years of experience in shooting performed under four attentional focus strategies in a counterbalanced design. In each strategy, two blocks (each consisting of 20 trials) were conducted. Shooters' performance was recorded using SCATT device and analyzed using the factorial variance analysis with repeated measure. RESULTS: Results showed that the interactional effects of internal-external/relevant-irrelevant focuses of attention were significant on shooting record, shooting accumulation, and stability on the target center. Results suggest that the external-relevant attentional focus strategies were more effective than other focus strategies. CONCLUSION: The results of the study support the hypothesis that external-relevant attentional focus produced better scores, better accumulation, more stability at the target center, and less average fluctuation. Therefore, this attentional focus strategy improves performance precision of military elite shooters.

Feedback about more accurate versus less accurate trials: differential effects on self-confidence and activation.

One purpose of the present study was to examine whether self-confidence or anxiety would be differentially affected byfeedback from more accurate rather than less accurate trials. The second purpose was to determine whether arousal variations (activation) would predict performance. On day 1, participants performed a golf putting task under one of two conditions: one group received feedback on the most accurate trials, whereas another group received feedback on the least accurate trials. On day 2, participants completed an anxiety questionnaire and performed a retention test. Shin conductance level, as a measure of arousal, was determined. The results indicated that feedback about more accurate trials resulted in more effective learning as well as increased self-confidence. Also, activation was a predictor of performance.
