- Aim: Physical conditioning of youth has always been a controversial topic as it raises ethical, physiological, and medical issues. Current recommendations and guidelines suggest that strength training is a relatively safe and worthwhile method in conditioning youth. This, however, requires well-informed coaches who follow age-appropriate strength training recommendations and guidelines, compiles well-designed strength training programs, and provides qualified supervision and instructions. The purpose of this study was to investigate coaches’ awareness of current recommendations and guidelines regarding strength training for youth.Method: A total of 39 football (US: soccer) coaches (34 males and 5 females) training boys in age groups 8–12 years were included in this study. Data were collected using an attitude statement questionnaire, and the assertions were based upon current recommendations and guidelines.Results: The results revealed significant differences among coaches in terms of knowledge of important aspects of strength training for youth.Conclusions: The results suggested that coaches in the present study were not aware of the latest recommendations and guidelines regarding strength training for youth.

- BACKGROUND: Physical activity provides fundamental health benefits and plays a positive role in physical well-being. The aim of this present study was to investigate whether a 6-month physical activity program could influence physical self-esteem and frequency of physical activity in physically inactive female high school students in short- and long-term periods and whether personality traits were related to physical activity behaviour and compliance with the program. METHODS: The study was a cluster-randomised controlled intervention study including 104 physically inactive female high school students aged 16-19 years, 60 females in an intervention group and 44 females in a control group. The intervention group exercised at sport centres at least once per week during a 6-month period. Questionnaires were used for evaluation. RESULTS: At a 6-month follow up, the intervention group improved physical self-perception in all subdomains and significantly improved physical condition, physical self-worth and self-related health compared to the control group. At 1-year follow up, 25 females out of 53 females were still physically active, and all ratings remained almost the same as at the 6-month follow up. There were no particular personality traits that were dominant in the groups. CONCLUSION: A 6-month physical activity program can positively influence physical self-esteem and the frequency of physical activity, both from a short- and long-term perspective.

- Objectives The heel-rise test is used to assess the strength and endurance of the plantar flexors in everyday clinical practice. However, several factors may affect outcomes, including sex, age, body mass index and activity level. The aims of this study were to revisit the reliability and normative values of this test, and establish normative equations accounting for several factors. Interventions Subjects performed single-legged heel rises to fatigue, standing on a 10 degrees incline, once on each leg. A subset of subjects (n = 32) repeated the test 1 week later. Reliability was quantified using intraclass (ICC) correlation coefficients and BlandAltman plots {mean difference [95% limits of agreement (LOA)]}, whereas the impact of sex, age, body mass index and activity level on the number of heel rises was determined using non-parametric regression models. Results The test showed excellent reliability (ICC = 1.0 right leg, 1.0 left leg), with mean between-day differences in the total number of heel-rise repetitions of 0.2 (95% LOA -6.2 to 6.5) and 0.1 (95% LOA -6.1 to 6.2) for right and left legs, respectively. Overall, males completed more repetitions than females (median 24 vs 21). However, older females (age >60 years) outperformed older males. According to the model, younger males with higher activity levels can complete the most heel rises. Conclusions The heel-rise test is highly reliable. The regression models herein can be employed by clinicians to evaluate the outcomes of heel-rise tests of individuals against a comparable normative population.

- Background: Health organizations suggest that adults ought to engage in at least 30 minutes of moderate-intensity daily physical activity. This study investigated the effects of a 30-minute single daily bout of brisk walking upon risk factors for CHD with blood lipid profile in particular. Methods: Thirty-three (25-45 y) adults, were randomly assigned into an exercise group (EG) (n=16, (9w) and a control group (CG) (n=17 (6w). The EG walked briskly 30 minutes daily during the 3 weeks test period. Compliance/adherence was maximal throughout the 3-week intervention due to stringent daily monitoring. Results: The EG showed a significant decrease in concentrations of low density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) during the intervention period. A significant inverse correlation between Δ energy expenditure/day and Δ LDL-C (r = -0.39, P<0.05) and an improvement in weight and BMI in the EG was found. Average steps during 30 minutes brisk walking bout was 3669 steps/bout generating a mean energy expenditure of 191 kcal/bout. Conclusions: The most unique findings were that daily single bouts of moderate-intensity physical activity for 30 minutes, during 3 weeks, induced favourable effects upon body weight, BMI and blood concentration of LDL-C and TC in healthy adults.

- In sports, there is a constant discussion about the hyper-pronation and supination of the foot during loading and its relation to injuries or discomfort. The purpose of the present study was to investigate the possible differences in the subtalar joint in the midstance phase of running, between individuals with Pes Planus and Pes Cavus, after 5 min and 45 min of running. Thirty-four subjects, meeting the requirements for Pes Planus (30 feet) and Pes Cavus (35 feet), according to the criteria for Medial Longitudinal Arch-angle, were included in the study. The calcaneal vertical angle, representing the eversion/inversion of the subtalar joint, was measured using with two-dimensional digital analysis and Dartfish Software with the subjects running barefoot on a treadmill, before and after 45 min of outside running wearing shoes. Both individuals with Pes Cavus and Pes Planus showed a significant increase in the calcaneal eversion (P<0.05) after 45 min of running. Between the groups, there was a significantly greater eversion of the Pes Planus, on the right foot, after 45 min of running (P<0.05) compared to the Pes Cavus. The effect of fatigue evident in the present study suggests that further biomechanical research should be considered when exposing the foot to the repetitive nature of running, conditions most likely responsible for the overrepresented overuse injuries among runners.

- OBJECTIVE: The aim of this study was to perform a 5-year follow-up of a 7-week multidisciplinary rehabilitation program focusing on pain, physical disability, anxiety and depression as well as stress and sick leave and to compare the results from the baseline, a 2-year follow-up and this 5-year follow-up. PARTICIPANTS: Out of 60 participants of the original rehabilitation program 54 were followed-up after 5 years. METHODS: The rehabilitation program was individually adapted and consisted of physical activity in several forms as well as theoretical and practical education. At baseline (start of study) and 2 and 5 years after completion of the rehabilitation program all participants were evaluated in terms of sick leave, pain rating (Visual Analogue Scale), the Disability Rating Index, Hospital Anxiety and Depression Scale, and Stress Test. RESULTS: Between the start of the program and the 5-year follow-up pain rating (P < 0.017) and the rate of full-time sick leave (P < 0.0005) decreased. Physical disability, anxiety, depression and stress were maintained from the 2-year follow-up until the 5-year follow-up. CONCLUSIONS: The rehabilitation program seemed to have had an effect on the participant's ability to manage with symptoms long after the end of the rehabilitation program. Most participants had returned to work, and reported less pain. The improvements made in physical disability and mental health prior to the 2-year follow-up were maintained at the 5-year follow-up occasion.

- The manner in which health professionals and coaches act and decide on treatment and prognosis can influence athletes in a way that not only strengthens them, but it can also reduce their confidence in their own ability. The purpose was to determine who has the responsibility for child and adolescent psychosocial support needed in connection with a severe sports injury as well as investigate whether coaches, physiotherapists and parents are aware of the support that is needed. Qualitative interviews with coaches, parents and physiotherapists with experience of serious sports injuries in young people aged 12 to 16 years old from different sports were analysed using content analysis. The study showed that all actors independently imparted communication as being the major problem and indicated that the role of a coordinator was missing. They imparted cognitive, emotional and behavioural reactions in children, which were considered to be more common in younger children as indicated in previous studies. Coaches felt they had lack of education and time; parents described their disappointment in caregivers and personality changes in their children in connection with the injury. Physiotherapists felt that rehabilitation was often served as a substitute for the sport and that they therefore had greater responsibility for the child than they had been educated for. Results should be communicated to participants who are involved in children's and adolescent's sports to increase their knowledge and thus allow them to be able to give our children the best possibility, regardless of whether they return to the sport or not.
