- Background: A relevant, but overlooked question is if self-reported physical activity and aerobic fitness are differently related to mental health. Purpose: To examine the relation between mental health and level of self-reported physical activity (SRPA) and aerobic fitness (AF), and whether AF mediates the relation between SRPA and mental health. Methods: Participating in the study were 177 voluntary subjects (49% men, 51% women) with a mean age of 39 years. Symptoms of depression and anxiety were measured through the Hospital Anxiety and Depression (HAD) scale, and the Shirom-Melamed Burnout Questionnaire (SMBQ) was used to evaluate self-reported symptoms of burnout. Leisure time SRPA during the last three months were measured using a single item. AF was measured by using the Åstrand bicycle test. Results: Self-reported physical activity, but not AF, was significantly related to self-reported symptoms of depression, anxiety, and burnout. Light to moderate physical activity that is performed regularly seems to be associated with more favorable mental health pattern compared with physical inactivity. No support was found for the mediating effect of AF of the physical activityemental health relationship. Conclusions: Self-reported behavior of regular physical activity seems to be more important to monitor than measures of AF when considering the potential preventive effects of physical activity on mental health.

- This study investigated if behavioral factors, treatment with behavioral support, readiness to change, fall self-efficacy, and activity habits could predict long-term adherence to an exercise program. Included in this study were 114 community-dwelling older adults who had participated in one of two home-based exercise interventions. Behavioral factors associated with adherence to the exercise program over 52 weeks were analyzed. The behavioral factors, specifically activity habits at baseline, significantly predicted adherence to the exercise program, with an odds ratio = 3.39, 95% confidence interval [1.38, 8.32], for exercise and an odds ratio = 6.11, 95% confidence interval [2.34, 15.94], for walks. Being allocated to a specific treatment including motivational interviewing was also significantly predictive: odds ratio = 2.47, 95% confidence interval [1.11, 5.49] for exercise adherence. In conclusion, activity habits and exercise in combination with motivational interviewing had a significant association with adherence to the exercise program at a 1-year follow-up.

Impact of Menstrual cycle-based Periodized training on Aerobic performance, a Clinical Trial study protocol—the IMPACT study
- 2024
-
Ingår i: Trials. - : BioMed Central (BMC). - 1745-6215. ; 25:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The menstrual cycle and its impact on training and performance are of growing interest. However, evidence is lacking whether periodized exercise based on the menstrual cycle is beneficial. The primary purpose of this proposed randomized, controlled trial, the IMPACT study, is to evaluate the effect of exercise periodization during different phases of the menstrual cycle, i.e., comparing follicular phase-based and luteal phase-based training with regular training during the menstrual cycle on physical performance in well-trained women.Methods: Healthy, well-trained, eumenorrheic women between 18 and 35 years (n = 120) will be recruited and first assessed for physical performance during a run-in menstrual cycle at different cycle phases and then randomized to three different interventions: follicular phase-based training, luteal phase-based training, or regular training during three menstrual cycles. The training intervention will consist of high-intensity spinning classes followed by strength training. The menstrual cycle phases will be determined by serum hormone analysis throughout the intervention period. Assessment of aerobic performance (primary outcome) and muscle strength, body composition, and blood markers will be performed at baseline and at the end of the intervention.Discussion: With a robust methodology, this study has the potential to provide evidence of the differential effects of exercise periodization during different phases of the menstrual cycle in female athletes.Trial registration: ClinicalTrials.gov NCT05697263 .

- OBJECTIVE:This article discusses the use of a third qualifier, subjective experience of involvement, as a supplement to the qualifiers of capacity and performance, to anchor activity and participation as separate endpoints on a continuum of actions.DESIGN:Empirical data from correlational studies were used for secondary analyses. The analyses were focused on the conceptual roots of the participation construct as indicated by the focus of policy documents, the support for a third qualifier as indicated by correlational data, differences between self-ratings and ratings by others in measuring subjective experience of involvement, and the empirical support for a split between activity and participation in different domains of the activity and participation component.RESULTS:Participation seems to have two conceptual roots, one sociologic and one psychologic. The correlational pattern between the qualifiers of capacity, performance, and subjective experience of involvement indicates a possible split between activity and participation. Self-ratings of participation provide information not obtained through ratings by others, and later domains in the activities and participation component fit better with measures of experienced involvement than earlier domains did.CONCLUSIONS:The results from secondary analyses provide preliminary support for the use of a third qualifier measuring subjective experience of involvement to facilitate the split between activity and participation in the International Classification of Functioning, Disability and Health, Children and Youth version, activity and participation domain.

Tidskriftsartikel (refereegranskat)abstract
- The ranking of football players has always engaged media and supporters worldwide. The different views on ranking are due to two reasons. First, leagues are heterogeneous with various qualities. Second, fans often rely on different performance measures and statistics, or just unmeasurable actions. Despite the fact that team and player bias will never disappear, this paper aims to objectively evaluate the efficiency of 42 top scorers who have played in the UEFA Champions League (UCL) over a six years period, (2006/07 - 2011/12), based on official match-play “multi-input and output” statistics, using input- and output oriented DEA models.

- Recently, we published self-reported data concerning the perceived effects of the menstrual cycle and hormonal contraceptives on the training and performance of 1086 female athletes participating in 57 sports. However, studies comparing differences between sports with large sample sizes are lacking. The aim of this ancillary study was to compare the impact of the menstrual cycle and hormonal contraceptives on training and performance between the three largest sports in the cohort, that is, football, handball, and orienteering, as well as the knowledge and support provided to the female athletes engaged in these sports. The results are from a web-based questionnaire completed by 312 football players, 243 handball players, and 93 orienteers. A total of 54% of the orienteers planned their training based on the menstrual cycle, which was a higher proportion compared to football (45%) and handball (29%) players (p < 0.05). Fewer football players believed that the menstrual cycle had an impact on their performance during training and competition compared to the two other sports. A high proportion of the athletes used hormonal contraceptives in all three sports, but a lower proportion of the orienteers (40%) used hormonal contraceptives compared to football (76%) and handball players (66%) (p < 0.05). Football and handball players received overall more support than orienteers, and the support was mostly provided by a physiotherapist and/or a strength and conditioner coach besides the main coach. These findings demonstrate that the perceived influence of the menstrual cycle and hormonal contraceptives on training and performance differs between endurance athletes in orienteering compared to team-sport athletes in football and handball.

- Physical activity has a demonstrated positive effect on youth depressive symptoms. However, very few studies have explored the bi-directionality of the links between physical activity and depression. The present study aims at filling this gap and tests whether any associations are moderated by sex. Moreover, the role of subtype of depressive symptoms, vegetative (i.e., lack of energy, poor sleep) or non-vegetative (i.e., mood-related), is explored. Participants were 910 12-13 year-old Swedish adolescents (56% girls) who answered a three-wave survey at ages 12-13 (T1), 15-16 (T2), and 18-19 (T3). Using a cross-lagged structural model, depression predicted decreased frequency of vigorous physical activity (VPA) from T1 to T2 (& beta; = -0.09, p < .05) and from T2 to T3 (& beta; = -0.10, p < .01), while frequency of VPA at T2 decreased depression at T3 (& beta; = -0.12, p < .05). Associations did not differ between boys and girls. Non-vegetative symptoms predicted decreased frequency of VPA from T1 to T2 (& beta; = -0.10, p < .05), while frequency of VPA at T2 predicted decreased non-vegetative symptoms at T3 (& beta; = -0.15, p < .05). Vegetative symptoms predicted decreased frequency of VPA from T1 to T2 (& beta; = -0.09, p < .05), while have a reciprocal influence with VPA from T2 to T3. Overall, our results highlight an association across adolescence between VPA and depression. The association becomes stronger and reciprocal in middle adolescence, which suggests this period as an effective developmental time to plan physical-activity-based interventions to decrease youth depressive symptoms.
