Mental health in student-athletes in Norwegian lower secondary sport schools

Objectives

The Norwegian sport school system offers a method for helping young dual-career athletes achieve their best both in academia and sports. However, there remains a concern that pursuing dual careers at a young age may leave some student-athletes vulnerable to poor mental health outcomes. The aim of this study was to investigate the association between gender, grade, and sport type and problematic scores on school burn-out, sport burn-out, self-esteem and psychological distress in student-athletes within a sample of Norwegian lower secondary schools.

Methods

A sample of 642 student-athletes (ages 12-14) in grades 8-10 across 8 Norwegian lower secondary sport schools completed questionnaires on burn-out, self-esteem and psychological distress at the beginning of the school year.

Results

Females were more likely to report high levels of sport-related burn-out and psychological distress, and low self-esteem; older student-athletes were more likely to report severe school-related and sport-related burn-out; and individual sport student-athletes were more likely to report high levels of psychological distress.

Conclusions

Lower secondary sport schools in Norway may seek to be aware of the challenges facing student-athletes for informed practical steps to protect their mental health and maximise their outcomes as school students and athletes.

Unveiling the relationship of physical literacy with muscular fitness and muscle-strengthening activities in adolescents: the EHDLA study

Objective

This study evaluated the relationship between physical literacy (PL) and muscular fitness (MF) as well as muscle-strengthening activities (MSA) in adolescents.

Methods

A secondary cross-sectional study included 823 adolescents (45.1% boys) from the Eating Healthy and Daily Life Activities Study. The Spanish Perceived Physical Literacy Instrument for Adolescents (S-PPLI) assessed the participants' perceived PL. The evaluation of MF in the young population was conducted using the Assessing the Levels of Physical Activity and Fitness (ALPHA-FIT) test battery. MSA were assessed by the following question: 'In the past week, how many days did you exercise to strengthen or tone the muscle, such as through push-ups, sit-ups or lifting weights?' To examine the associations between S-PPLI scores and handgrip strength, standing long jump and MSA days in adolescents, we employed generalised additive models.

Results

Participants with high perceived physical literacty (PPL) had the highest handgrip strength (mean=25.1; PPL had the highest handgrip strength (mean=25.1; bias-corrected and accelerated (BCa) bootstrapped 95% CI 24.2 to 26.0) and standing long jump (mean=149.7; confidence interval (CI) 24.2 to 26.0) and standing long jump (mean=149.7; 24.2 to 26.0) and standing long jump (mean=149.7; BCa bootstrapped 95% CI 145.8 to 153.5). Conversely, those adolescents with low PPL had the lowest handgrip strength (mean=23.1; BCa bootstrapped 95% CI 22.3 to 23.8) and standing long jump (mean=137.3; BCa bootstrapped 95% CI 133.9 to 140.6). For MSA, adolescents with high PPL had the highest mean of MSA days (mean=3.0; BCa bootstrapped 95% CI 2.8 to 3.3), while the lowest mean was observed for those with low PPL (mean=2.0; BCa bootstrapped 95% CI 1.8 to 2.2).

Conclusion

A high level of PL was associated with higher levels of MF and MSA among Spanish adolescents.

Run, walk, cheer or volunteer: a patient and public involvement survey

Background

Children with chronic diseases have been reported to participate in less regular physical activity (PA) than peers without chronic diseases; and less than recommended in guidelines. Sheffield Children's Foundation Trust (SCFT) is an Active Hospitals pilot site, exploring options to facilitate PA for all children. One option is collaboration with Junior Parkrun: a free, weekly 2 km running event for children. The team investigated whether Junior Parkrun was of interest to guardians of children attending SCFT to increase PA.

Aims

This patient and public involvement survey assessed perceptions of PA for children attending SCFT according to their accompanying guardians. This will inform a possible collaboration between SCFT and Junior Parkrun.

Methods

A three-part, 14-question survey was developed, including demographics (age, ethnicity, postcode); perceptions of PA (barriers and facilitators); PA behaviours self-reported on Likert scales; and perceptions of Junior Parkrun. Guardians were asked whether they and their child would be interested in attending Junior Parkrun with SCFT staff support. This was distributed to guardians of children attending outpatient appointments.

Results

126 guardians responded. The average age of child was 10 years 10 months. 29.1% of guardians supported daily PA for their child. Almost half of respondents reported their child would be interested in attending Junior Parkrun. Of those not interested, the most common reason was travel.

Conclusion

The findings highlighted PA barriers perceived by guardians, and identified that almost half of respondents would be interested in attending Junior Parkrun. A collaboration between Junior Parkrun and SCFT could be explored.

Can't play, won't play: longitudinal changes in perceived barriers to participation in sports clubs across the child-adolescent transition

Background

Participation in sports is associated with numerous physical and psychosocial health benefits, however, participation declines with age, and knowledge of perceived barriers to participation in children is lacking. This longitudinal study of children and adolescents aimed to use the ecological model of physical activity to assess changes in barriers to participation in sports clubs to identify age-specific and weight-specific targets for intervention.

Methods

Longitudinal study—Perceived barriers to sports participation were collected from a birth cohort, the Gateshead Millennium Study (n>500) at ages 9 and 12 years. The open-ended question ‘Do you find it hard to take part in sports clubs for any reason?’ was completed with free text and analysed using content analysis, and the social–ecological model of physical activity.

Results

Barriers from across the social-ecological model were reported. Barriers at 9 years were predominantly of a physical environmental nature, and required high parental involvement (for transport, money, permission), or were associated with a lack of suitable clubs. At 12 years, perceived barriers were predominantly classed as intrapersonal (‘they're boring’) or social environmental (‘my friends don't go’). Perceived barriers were not associated with weight status.

Conclusions

Perceived barriers to sports participation change rapidly in childhood and adolescence. Future interventions aiming to increase sports participation in children and adolescents should target specific age groups, should consider the rapid changes which occur in adolescence, and aim to address prominent barriers from across the socioecological model. Perceived barriers may be unrelated to current weight status, allowing for more inclusive solutions.

Sixty minutes of what? A developing brain perspective for activating children with an integrative exercise approach

Current recommendations for physical activity in children overlook the critical importance of motor skill acquisition early in life. Instead, they focus on the quantitative aspects of physical activity (eg, accumulate 60 min of daily moderate to vigorous physical activity) and selected health-related components of physical fitness (eg, aerobic fitness, muscular strength, muscular endurance, flexibility and body composition). This focus on exercise quantity in youth may limit considerations of qualitative aspects of programme design which include (1) skill development, (2) socialisation and (3) enjoyment of exercise. The timing of brain development and associated neuroplasticity for motor skill learning makes the preadolescence period a critical time to develop and reinforce fundamental movement skills in boys and girls. Children who do not participate regularly in structured motor skill-enriched activities during physical education classes or diverse youth sports programmes may never reach their genetic potential for motor skill control which underlies sustainable physical fitness later in life. The goals of this review are twofold: (1) challenge current dogma that is currently focused on the quantitative rather than qualitative aspects of physical activity recommendations for youth and (2) synthesise the latest evidence regarding the brain and motor control that will provide the foundation for integrative exercise programming that provide a framework sustainable activity for life.

Hydration and thermal strain during tennis in the heat

Competitive tennis in the heat can prompt substantial sweat losses and extensive consequent body water and electrolyte deficits, as well as a level of thermal strain that considerably challenges a player's physiology, perception of effort, and on-court well-being and performance. Adequate hydration and optimal performance can be notably difficult to maintain when multiple same-day matches are played on successive days in hot weather. Despite the recognised effects of the heat, much more research needs to be carried out to better appreciate the broader scope and full extent of the physiological demands and hydration and thermal strain challenges facing junior and adult players in various environments, venues and competition scenarios. However, certain recommendations of best practices should be emphasised to minimise exertional heat illness risk and improve player safety, well-being and on-court performance.

Objectively measured physical activity trajectories predict adolescent bone strength: Iowa Bone Development Study

BACKGROUND

Physical activity improves bone strength and reduces the risk for osteoporotic fractures. However, there are substantial gaps in our knowledge as to when, how and how much activity is optimal for bone health.

PURPOSE

In this cohort study, we examined developmental trajectories of objectively measured physical activity from childhood to adolescence to discern if moderate-and-vigorous intensity physical activity (MVPA) predicts bone strength.

METHODS

Starting at age 5 and continuing at 8, 11, 13, 15 and 17 years, Iowa Bone Development Study participants (n=530) wore an accelerometer for 3-5 days. At age 17, we assessed dual X-ray energy absorptiometry outcomes of mass and estimated geometry (femoral neck cross-sectional area and section modulus). We also assessed geometric properties (bone stress index and polar moment of inertia) of the tibia using peripheral computer quantitative tomography. Latent class modelling was used to construct developmental trajectories of MVPA from childhood to late adolescence. General linear models were used to examine the trajectory groups as predictors of age 17 bone outcomes.

RESULTS

Girls and boys who accumulated the most MVPA had greater bone mass and better geometry at 17 years when compared to less active peers. The proportion of participants achieving high levels of MVPA throughout childhood was very low (<6% in girls) and by late adolescence almost all girls were inactive.

CONCLUSIONS

Bone health benefits of physical activity are not being realised due to low levels of activity for most youth, especially in girls.

Built environment characteristics and parent active transportation are associated with active travel to school in youth age 12-15

PURPOSE

To investigate the relation of factors from multiple levels of ecological models (ie, individual, interpersonal and environmental) to active travel to/from school in an observational study of young adolescents.

METHODS

Participants were 294 12-15-year olds living within two miles of their school. Demographic, psychosocial and perceived built environment characteristics around the home were measured by survey, and objective built environment factors around home and school were assessed in Geographic Information Systems (GIS). Mixed effects multinomial regression models tested correlates of engaging in 1-4 (vs 0) and 5-10 (vs 0) active trips/week to/from school, adjusted for distance and other covariates.

RESULTS

64% of participants reported ≥1 active trip/week to/from school. Significant correlates of occasional and/or habitual active travel to/from school included barriers (ORs=0.27 and 0.15), parent modelling of active travel (OR=3.27 for habitual), perceived street connectivity (OR=1.78 for occasional), perceived pedestrian safety around home (OR=2.04 for habitual), objective street connectivity around home (OR=0.97 for occasional), objective residential density around home (ORs=1.10 and 1.11) and objective residential density around school (OR=1.14 for habitual). Parent modelling interacted with pedestrian safety in explaining active travel to/from school.

CONCLUSIONS

Results supported multilevel correlates of adolescents' active travel to school, consistent with ecological models. Correlates of occasional and habitual active travel to/from school were similar. Built environment attributes around schools, particularly residential density, should be considered when siting new schools and redeveloping neighbourhoods around existing schools.

Interventions designed to reduce sedentary behaviours in young people: a review of reviews

BACKGROUND

Leisure time is increasingly spent in sedentary pursuits such as screen-viewing (eg, television/DVD viewing and computer use), motorised travel, school/work and sitting-based socialising (eg, social media and chatting). Sedentary screen time, particularly TV, appears to play an important role in the aetiology of obesity due to its co-occurrence with other unhealthy behaviours such as snacking on energy-dense foods, low levels of physical activity and inadequate sleep. More information is needed on how to reduce sedentary behaviours. Most interventions have focused on young people and a number of systematic reviews exist on this topic.

OBJECTIVE

To synthesise systematic reviews and meta-analyses of interventions aimed at decreasing sedentary behaviours among children and adolescents.

METHODS

Papers were located from computerised and manual searches. Included articles were English language systematic reviews or meta-analyses of interventions aiming at reducing sedentary behaviour in children (<11 years) and adolescents (12-18 years).

RESULTS

Ten papers met the inclusion criteria and were analysed. All reviews concluded some level of effectiveness in reducing time spent in sedentary behaviour. When an effect size was reported, there was a small but significant reduction in sedentary time (highest effect size=-0.29; CI -0.35 to -0.22). Moderator analyses showed a trend favouring interventions with children younger than 6 years. Effective strategies include the involvement of family, behavioural interventions and electronic TV monitoring devices.

CONCLUSIONS

Results from systematic reviews and meta-analyses show that interventions to reduce children's sedentary behaviour have a small but significant effect. Future research should expand these findings examining interventions targeting different types of sedentary behaviours and the effectiveness of specific behaviour change techniques across different contexts and settings.

Can resistance training change the strength, body composition and self-concept of overweight and obese adolescent males? A randomised controlled trial

BACKGROUND/AIM

Resistance training is an exercise modality at which overweight and obese adolescents can excel and which can therefore positively affect their psychological well-being. The aim of this study was to determine the effect of a 6-month resistance training intervention on the self-concept strength and body composition of overweight and obese adolescent males.

METHODS

56 overweight and obese males aged 13-17 years were randomly allocated to an Intervention (n=30) or Control (n=26) group. Primary (psychological) and secondary (strength and body composition) outcomes were assessed at baseline as well as at 3 (halfway through the intervention), 6 (immediately postintervention) and 12 months follow-up. Random effects mixed modelling was used to determine the effects of the intervention.

RESULTS

Statistically significant differences between the Intervention and Control groups were observed at 3-month and 6-month assessments for exercise self-efficacy, resistance training confidence and self-esteem. Large increases in strength for the Intervention group, relative to Controls, were also observed with no substantial changes in body composition shown for either group. Values for all variables returned to baseline following completion of the programme.

CONCLUSIONS

A 6-month resistance training intervention can positively affect the self-concept and strength of overweight and obese adolescent boys.

Benefits of combining inspiratory muscle with 'whole muscle' training in children with cystic fibrosis: a randomised controlled trial

BACKGROUND

The purpose of this study (randomised controlled trial) was to assess the effects of an 8-week combined 'whole muscle' (resistance+aerobic) and inspiratory muscle training (IMT) on lung volume, inspiratory muscle strength (PImax) and cardiorespiratory fitness (VO2 peak) (primary outcomes), and dynamic muscle strength, body composition and quality of life in paediatric outpatients with CF (cystic fibrosis, secondary outcomes). We also determined the effects of a detraining period.

METHODS

Participants were randomly allocated with a block on gender to a control (standard therapy) or intervention group (initial n=10 (6 boys) in each group; age 10±1 and 11±1 years). The latter group performed a combined programme (IMT (2 sessions/day) and aerobic+strength exercises (3 days/week, in-hospital)) that was followed by a 4-week detraining period. All participants were evaluated at baseline, post-training and detraining.

RESULTS

Adherence to the training programme averaged 97.5%±1.7%. There was a significant interaction (group×time) effect for PImax, VO2peak and five-repetition maximum strength (leg-press, bench-press, seated-row) (all (p<0.001), and also for %fat (p<0.023) and %fat-free mass (p=0.001), with training exerting a significant beneficial effect only in the intervention group, which was maintained after detraining for PImax and leg-press.

CONCLUSION

The relatively short-term (8-week) training programme used here induced significant benefits in important health phenotypes of paediatric patients with CF. IMT is an easily applicable intervention that could be included, together with supervised exercise training in the standard care of these patients.

Moderate-and-vigorous physical activity from adolescence to adulthood and subclinical atherosclerosis in adulthood: prospective observations from the European Youth Heart Study

AIM

To investigate the independent associations between mean exposure to or the change in moderate-and-vigorous physical activity (PA) from adolescence to adulthood and subclinical atherosclerosis in adulthood.

METHODS

This was a prospective cohort study among Danish boys and girls (N=277) followed for up to 12 years (age 15.7 (0.4) at baseline) enrolled in the European Youth Heart Study. PA intensity was objectively measured at baseline and follow-up, and ultrasonography was performed on the Carotid arteries at follow-up. Data on carotid intima-media thickness (cIMT), Carotid Compliance and Young's Elastic Modules were used as outcome measures.

RESULTS

In the multivariable analyses (adjusted for personal-lifestyle and demographic factors) the mean exposure to moderate-and-vigorous PA from adolescence to adulthood was negatively associated with Young's Elastic Modules (β=-0.001×10(3) kPa (95% CI -0.0015 to -0.0002), p=0.02) and positively associated with Carotid Compliance (β=0.004 mm(2) kPa(-1) (95% CI 0.002 to 0.008), p=0.003) and cIMT (β=0.0003 mm (95% CI 0.00001 to 0.0007), p=0.013). Increases in moderate-and-vigorous PA from adolescence to adulthood were negatively associated with Young's Elastic Modules in adulthood (β=-0.00007×10(3) kPa (95% CI -0.0012 to -0.0001), p=0.01). Furthermore, participants with the largest decline in moderate-and-vigorous PA from adolescence to adulthood displayed significantly less compliant arteries compared with the remaining sample (p<0.05).

CONCLUSIONS

High mean exposure to moderate-and-vigorous PA levels and increases herein were independently associated with lower levels of carotid arterial stiffness in adulthood.

Effectiveness of the PLAYgrounds programme on PA levels during recess in 6-year-old to 12-year-old children

AIMS

Worldwide levels of daily physical activity (PA) in children are low. This has negative health consequences. Schools have been recognised as key settings to promote PA. This study evaluates the effectiveness of the playground programme PLAYgrounds on increasing PA.

METHODS

PLAYgrounds was evaluated by a controlled trial, with a follow-up during one school year (10 months). Accelerometer data were collected on 1500 children in total, divided over 19 sampling moments (every 2 weeks). SOPLAY data were collected at nine sampling moments (once a month). Four intervention and four control schools were matched for playground size, number of pupils and PA levels at baseline. The intervention consisted of restructuring the playground by playground markings and by encouragement of the active use of the playground, through the provision of play equipment and educational measures such as adult encouragement and supporting physical education classes. Multilevel regression analyses were performed to analyse the effects of the intervention.

RESULTS

PA levels in the intervention group (moderate PA) were significantly different (p<0.001) from the control group (light PA). During the intervention on an average 77.3% of the children engaged in moderate-to-vigorous physical activity in the intervention group and 38.7% in the control group. The effect of the intervention was significantly stronger for girls than for boys (p<0.001).

CONCLUSIONS

The PLAYgrounds programme was effective in increasing PA levels in children during recess over the course of one school year. Thus, the programme could be used to provide structured PA promotion.
