Aim: To compare the acute effects of two resistance exercise sessions with different partial blood flow restrictions (BFR) on hemodynamic parameters and cardiac autonomic modulation in older women with metabolic syndrome. Methods: Thirty-nine older women (64.4 ± 4.5 years) were allocated into three groups: BFR0 = resistance exercise (20%, 1 maximum repetition [MR]) + 0% BFR; BFR60 = 20% 1 MR resistance exercise + 60% BFR; and BFR80 = 20% 1MR resistance exercise + 80% BFR. Results: A reduction of 14 mmHg (BFR60 group) and 13 mmHg (BRF80 group) was observed 48 hr after the first exercise session, while vagal modulation was increased in the BRF60 group after 24 and 48 hr. Conclusion: A low-intensity resistance exercise session with 60% and 80% of BFR resulted in blood pressure (systolic, diastolic, and mean) reduction and positive changes on heart rate variability after 24 h of a RE session.

Background: In Denmark, most children are not sufficiently physically active and only a few interventions have been found to increase long-term physical activity among overweight and obese children. The aim of our study was to investigate if children are physically active in correspondence to Danish recommendations after attending a multicomponent-overnight camp. Methods: A questionnaire was developed to estimate children’s physical activity level and behavior and investigate how transport, economy, availability, time, motivation, and knowledge about physical activity affect children’s physical activity level and behavior. Results: In this study, 60.9% of the children did vigorous physical activity (VPA) minimum 30 minutes 3 times per week up to 3 years after camp. Most children were physically active at a sports club (44.3%) and only 5.7% of the children did not participate in physical activity. Parental physical activity and child motivation toward physical activity were significantly (P < .05) associated with children doing VPA. Conclusion: Our findings suggest that 60.9% of children who attended camp engage in VPA after camp, which compared with a recent Danish study, is more frequent than children who did not attend camp. Further investigations are needed to determine the long-term health effects in children attending interventions such as multicomponent-overnight camps.

Background: Studies related to the motor performance of children have suggested an interaction between organisms and the environment. Although motor development seems to be similar among people, the behavior is specific to the context that people are part of. Thus, the aim of this study was to compare the fundamental motor skill performance between indigenous (IN) and nonindigenous children. Methods: One hundred and thirteen children (43 IN and 70 nonindigenous children) between 8 and 10 years of age underwent the Test of Gross Motor Development—2. Results: A multivariate analysis showed a significant group main effect on both locomotor (p < .01) and object control (p < .01) performance with large and medium effect sizes (

This best practice paper reflects on a pilot coach education program designed for women coaching Australian Rules football. Focused on enhancing self-regulation, and underpinned by a growth mindset framework, the “Coach like a Woman” program was delivered to a selected group of female coaches either working in or having been identified with the potential to coach at high-performance levels. This manuscript describes the program content and discusses the key insights identified by the delivery team. Creating a community of practice encouraged the transfer of knowledge and experience between the enrolled coaches, which increased competence and self-confidence. Providing an understanding of behavioral tendencies enhanced positive self-talk and aided self-regulation by the coaches. The delivery of the program and challenges experienced are also discussed. This reflection on the program is provided to assist future developments in coach education.

Activity trackers provide real-time sedentary behavior (SB) and physical activity (PA) data enabling feedback to support behavior change. The validity of activity trackers in an obese population in a free-living environment is largely unknown. This study determined the convergent validity of the Fitbit Charge 2 in measuring SB and PA in overweight adults. The participants (n = 59; M ± SD: age = 48 ± 11 years; body mass index = 34 ± 4 kg/m2) concurrently wore a Charge 2 and ActiGraph GT3X+ accelerometer for 8 days. The same waking wear periods were analyzed, and standard cut points for GT3X+ and proprietary algorithms for the Charge 2, together with a daily step count, were used. Associations between outputs, mean difference (MD) and limits of agreement (LOA), and relative differences were assessed. There was substantial association between devices (intraclass correlation coefficients from .504, 95% confidence interval [.287, .672] for SB, to .925, 95% confidence interval [.877, .955] for step count). In comparison to the GT3X+, the Charge 2 overestimated SB (MD = 37, LOA = −129 to 204 min/day), moderate to vigorous PA (MD = 15, LOA = −49 to 79 min/day), and steps (MD = 1,813, LOA = −1,066 to 4,691 steps/day), and underestimated light PA (MD = −32, LOA = −123 to 58 min/day). The Charge 2 may be a useful tool for self-monitoring of SB and PA in an overweight population, as mostly good agreement was demonstrated with the GT3X+. However, there were mean and relative differences, and the implications of these need to be considered for overweight adult populations who are already at risk of being highly sedentary and insufficiently active.

The International Physical Activity Questionnaire (IPAQ) is a widely used self-reported physical activity (PA) measure developed to allow for international cross-country comparisons. Due to its unavailability, the aim of this study was to translate the IPAQ-long to Maltese and undertake reliability testing. The IPAQ-long English version was translated into Maltese following the IPAQ guidelines, which included backwards translation. Maltese-speaking participants, aged between 18 and 69 years, were recruited through convenience sampling (n = 170). Participants completed the IPAQ-long twice within an 8- to 48-hr period. PA was calculated in MET minutes per week, and reliability was calculated using the Spearman correlation, intraclass correlation coefficient, concordance correlation coefficient, and Bland–Altman plots. A total of 155 participants completed the questionnaire at two time points. Spearman correlation was .83 (.76–.88) for total PA and .84 (.77–.89) for total sitting time. The intraclass correlation coefficient was .83 (.76–.88) and the concordance correlation coefficient was .75–.87 for total PA. The lowest reliability was for total transport, with a concordance correlation coefficient of .21−.45. Bland–Altman plots highlight that 95% of the differences fell within 2 SDs from the mean. Since the Maltese IPAQ-long has similar reliability to the English version, the authors recommend that health care professionals and PA practitioners use this tool when examining population-level PA among Maltese-speaking individuals.

Background: To examine if major life changes over a 4-year period among 34- to 49-year-old adults (mean = 41.8, SD = 5.0) were associated with a change in physical activity in men (37.7%) and women (62.3%). Methods: Daily steps and aerobic steps (steps that lasted for at least 10 min without interruption at a pace of >60 steps/min) were collected from 1051 participants in 2007 and 2011. Changes in marital status, work status, and residence and the birth of a child were determined from both time points. A latent change score model was used to examine mean changes in daily total steps, aerobic steps, and nonaerobic steps (total steps minus aerobic steps). Results: Women who had a first child in the 4-year period had a decrease in their nonaerobic steps (P = .001). Men who divorced in the 4-year period had a decrease in their nonaerobic steps (P = .020), whereas women who recoupled decreased their total steps (P = .030). Conclusions: Counseling for parents having a first child on how to increase physical activity in their everyday life could potentially have an influence on an individual’s physical activity.
