Objective: to carry out an analysis of the consequences for mental health arising from the period of social isolation during the COVID-19 pandemic and to foreshadow coping strategies to minimize them. Methodology: this is an integrative literature review, carried out based on the search for scientific publications indexed in the databases: MEDLINE via PubMed, Europe PMC, Lilacs and SciELO. The following descriptors were used: COVID-19, social isolation, pandemics and mental health. At the end of the searches, 49 publications met the eligibility criteria and were selected to compose the study. Results: in view of the findings extracted from the selected studies, it was noticed that individuals subjected to social isolation are more susceptible to presenting mental health disorders, due to deprivation and social restraint, with symptoms of psychological distress, especially related to stress, anxiety and depression. Conclusion: this study allowed us to reflect on the need to ensure clear and informative communication on strategies to reduce these symptoms of psychological distress, in addition to providing fundamental psychological and social support for these vulnerable individuals.

The study showed that both experimental groups presented favorable results for BMD, strength, FA and QoL. However, the RT3 showed the best results compared to other groups after 13 months of intervention.

Abstract:Background: The objective of this study was to determine the effects of different physical activity (PA) programs on bone density, balance and quality of life of postmenopausal women taking concomitant alendronate. A quasi-experimental study was conducted with 35 volunteers divided into four groups: practitioners of resistance training (RTG, n ¼ 9, 49.8±4.2 years), judo (JUG, n ¼ 11, 52.2±5.3 years), water aerobics (WAG, n ¼ 8, 57.1±7.4 years) and the control group (CG, n ¼ 7, 53.8±4.4 years). Methods: The following assessment tools were used: bone mineral density (BMD) measured by dual X-ray absorptiometry of the spine and proximal femur, the 'Osteoporosis Assessment Questionnaire' (OPAQ) and the 'Static Balance Test with Visual Control'. The physical activities were planned for 12 months in cycles with different intensities. A two-way analysis of variance (ANOVA) was used for analysis between groups, and a Scheffé post-hoc test was used for multiple comparisons. Results: The multiple comparisons results showed that the RTG and JUG groups were significantly more efficient in the variables studied, including: lumbar BMD (Á% ¼ 6.8%, p ¼ 0.001), balance (Á% ¼ 21.4%, p ¼ 0.01), OPAQ (Á% ¼ 9.1%, p ¼ 0.005) and lumbar BMD (Á% ¼ 6.4%, p ¼ 0.003), balance (Á% ¼ 14%, p ¼ 0.02) and OPAQ (Á% ¼ 16.8%, p ¼ 0.000) compared with the CG. Furthermore, the RTG (Á% ¼ 4.8%, p ¼ 0.02) was significantly better than the WAG for the neck of femur BMD, and the JUG (Á% ¼ 16.8, p ¼ 0.0003) also demonstrated superiority to the WAG in the OPAQ. Conclusions: The physical activities studied appear to improve BMD, balance and quality of life of postmenopausal women taking a bisphosphonate. In this small sample, the RTG and the JUG groups were superior to the other groups.

The purpose of the current study was to compare serum creatine kinase (CK) and lactate dehydrogenase (LDH) concentrations at multiple time points after resistance exercise sessions that incorporated different rest intervals between sets and exercises. Twenty untrained men (18.65+/-0.49 years, 68.30+/-7.98 kg, and 174.4+/-4.80 cm) performed 2 resistance exercise sessions (i.e., 3 sets with 80% 1 repetition maximum for 5 upper-body exercises) with either 1-minute (SEQ1) or 3-minute (SEQ3) rest between sets and exercises. For each session, CK and LDH concentrations were measured before exercise (PRE) and 24, 48, and 72 hours after exercise (24P, 48P, and 72P). Subjects lifted a 24% greater (p<0.05) volume load during SEQ3 than during SEQ1. Within SEQ1, significant differences in CK concentrations were demonstrated between most time points, except between 24P and 72P. Similarly, within SEQ3, significant differences in CK concentrations were demonstrated between most time points, except between 24P and 72P and between 48P and 72P. The CK concentrations were highest at 48P for both sessions. When the CK concentrations were compared between SEQ1 and SEQ3, no significant differences were demonstrated at any time point. Within SEQ1, a significant difference in LDH concentration was demonstrated between 48P and 72P. Within SEQ3, significant differences in LDH concentrations were demonstrated between PRE and 24P and between PRE and 48P. The LDH concentrations were highest at 72P for SEQ1 and at 24P for SEQ3. When the LDH concentrations were compared between SEQ1 and SEQ3, no significant differences were demonstrated at any time point. These results suggest that muscle damage was similar between rest intervals; however, the volume load completed to induce the muscle damage was significantly greater when 3-minute rest intervals were employed. Therefore, when considered relative to the volume load completed, 1-minute rest intervals during resistance exercise may invoke greater muscle damage.
