Background: The incidence of acute hamstring injuries is high in several sports, including the different forms of football. Purpose: The authors investigated the preventive effect of eccentric strengthening of the hamstring muscles using the Nordic hamstring exercise compared with no additional hamstring exercise on the rate of acute hamstring injuries in male soccer players. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Fifty Danish male professional and amateur soccer teams (942 players) were allocated to an intervention group (461 players) or a control group (481 players). Players in the intervention group conducted a 10-week progressive eccentric training program followed by a weekly seasonal program, whereas players in the control group followed their usual training program. The main outcome measures were numbers of overall, new, and recurrent acute hamstring injuries during 1 full soccer season. Results: Fifty-two acute hamstring injuries in the control group compared with 15 injuries in the intervention group were registered. Comparing intervention versus the control group, overall acute hamstring injury rates per 100 player seasons were 3.8 versus 13.1 (adjusted rate ratio [RR], 0.293; 95% confidence interval [CI], 0.150-0.572; P < .001). New injury rates per 100 player seasons were 3.1 versus 8.1 (RR, 0.410; 95% CI, 0.180-0.933; P = .034), whereas recurrent injury rates per 100 player seasons were 7.1 versus 45.8 (RR, 0.137; 95% CI, 0.037-0.509; P = .003). Number needed to treat [NNT] to prevent 1 acute hamstring injury (new or recurrent) is 13 (95% CI, 9-23) players. The NNT to prevent 1 new injury is 25 (95% CI, 15-72) players, and NNT to prevent 1 recurrent injury is 3 (95% CI, 2-6) players. Conclusion: In male professional and amateur soccer players, additional eccentric hamstring exercise decreased the rate of overall, new, and recurrent acute hamstring injuries.

AbstractWe evaluated a range of physical characteristics related to hamstring injuries, as well as the Nordic Hamstring Exercise compliance rate, and whether this influenced the rate hamstring injury. Subjects comprised 259 male soccer players from seven high schools randomly clustered into two groups, a Nordic Hamstring Exercise group and a control group. Training and match time were logged, as well as details of hamstring injury, and subsequent time lost to hamstring injury recorded over a period of 27 weeks. The Nordic Hamstring Exercise compliance rate, injury rate per 10000 playing hours and time-lost-to-sport-injury rate were calculated. The relative risk and hamstring injury severity were also calculated. The hamstring injury rate was 1.04/10 000 h in the control group and 0.88/10 000 h in the intervention group. The relative risk for hamstring injury was 1.14. The time-lost to injury rate was 1116.3/10 000 h in the control group and 113.7/10 000 h in the intervention group; with relative risk 9.81. The Nordic Hamstring Exercise in high school soccer players significantly reduced hamstring injury severity compared to a control intervention. Our results indicate that the time-lost to injury rate should be taken into account when analyzing the severity of hamstring injury.

AbstractMuscle strength imbalances and poor flexibility are frequently described as risk factors for hamstring injury. Preventive strategies include eccentric exercises, but the influence of field eccentric exercises on these risk factors remains unclear. We investigated the influence of a field hamstring eccentric program on hamstring strength and flexibility. Twenty-seven amateur athletes were randomly assigned to an intervention (n=13) or control group (n=14). In the intervention group, participants were involved in 15 sessions of four eccentric exercises. Peak torque, hamstring-to-quadriceps ratios, passive and active flexibility were analyzed. No significant modifications of strength, passive or active flexibility were observed in the control group (p>0.05). Hamstring eccentric peak torque (+7.1%) and functional hamstring-to-quadriceps ratios (9.3%) were significantly increased (p<0.05) in the intervention group, but not concentric strength (p<0.05). Passive straight leg raise was significantly increased by 11.4° (+12.7%, p<0.001), but not active flexibility (+3.1%, p>0.05). In conclusion, a 6-week eccentric program, including four field exercises for hamstring muscles, is an effective method of improving eccentric strength, functional ratios and, especially, passive flexibility. As this program may be easily implemented in a real-world context, this association of multiple eccentric exercises might be useful in an injury prevention strategy.

Abstract Background The present study assessed the prevalence of non-contact muscle injuries of the lower limbs, including hamstring injuries, in professional Russian soccer players who regularly perform Salah, an obligatory Muslim prayer performed 5 times a day. Methods Using a retrospective cohort study design, 68 professional male soccer players (excluding goalkeepers), 34 of whom were Muslims regularly performing Salah (exposure group) and 34 were randomly chosen non-Muslim players (control group), were included in the study. The groups were similar in their playing leagues, field positions, age (27 ± 3.1 vs 28 ± 4.2 years), and body mass index (22 ± 1.2 vs 23 ± 0.92 kg/m2). Results The incidence of hamstring injury was significantly lower in the exposure group (2 vs 14, p = 0.0085). A declining trend for the number of muscle injuries (either hamstring or not) was observed in the exposure group (11 vs 27, p = 0.0562). Two players in the exposure group and 11 in the control group (p = 0.0115, OR 0.1307, 95% CI 0.0276 to 0.5698) suffered a hamstring injury, with no statistically significant difference in the occurrence of other injuries. The total amount of the training and play days missed because of hamstring and other muscle injuries was significantly lower in the exposure group (24 vs 213 days, p = 0.0043, and 200 vs 344 days, p = 0.0066, respectively). Conclusion The prevalence of non-contact muscle injuries, including hamstring injuries, was lower in professional Russian soccer players who regularly performed Salah.

This study aimed to assess the feasibility of an educational intervention on hydration behavior in adolescent soccer players. A pilot study of a two-arm, non-randomized controlled cluster trial was conducted. A total of 316 players aged 13–16 agreed to participate. The response variables were the players’ participation in the intervention, their perception of the knowledge acquired, the usefulness and the overall assessment of the intervention. Hydration patterns and acquisition of knowledge on hydration behavior were also assessed. The intervention involved two elements: posters and a web app. A total of 259 adolescents completed the study (intervention group (IG) = 131; control group (CG) = 128). 80.6% of the players responded to the survey assessing the feasibility of the intervention. The mean number of correct answers regarding behavior was significantly higher in the IG (3.54; SD = 1.162) than in the CG (2.64; SD = 1.174) (p < 0.001). The water consumption pattern at all the clubs was ad libitum. Of the players, 10% did not drink any water at all during the game. In conclusion, this intervention has been shown to be feasible for implementation with adolescent soccer players. It suggests that hydration guidelines should be informed by personal factors and that ad libitum water consumption should be avoided.

Abstract Background Annually, about 16 million adolescent girls give birth, accounting for 11% of all births worldwide. Ninety-five percent of these births occur in low- and middle-income countries, and previous studies have addressed the need for parenting interventions in developing countries with limited health care resources to improve parenting behaviors. Objective To explore the effect of a brief training program for primigravid adolescents on parenting self-efficacy and mother-infant bonding. Subjects We enrolled 116 married pregnant adolescents. Methods This quasi-experimental study was conducted during August 22, 2016–February 3, 2017. The intervention group received three sessions of training on neonatal care, while the control group received the routine care. We evaluated parenting self-efficacy using the Perceived Maternal Parenting Self-Efficacy (PMP S-E) questionnaire, the mother-infant bonding using the Postpartum Bonding Questionnaire (PBQ) and social support by means of the Multidimensional Scale of Perceived Social Support (MSPSS). The participants were followed up for 1 month. Results The mean ages of the intervention and the control groups were 16.37 ± 0.97 and 16.27 ± 1.12 years, respectively. The intervention group obtained higher self-efficacy and bonding scores compared to the control group. The logistic regression model showed that the second (evoking behaviors) and the third (reading behavior or signaling) subscales of the PMP S-E, the route of delivery and women’s educational levels could predict the mother-infant bonding scores. Conclusion Primigravid adolescents can benefit from brief interventions during pregnancy through improving their parenting self-efficacy and mother-infant bonding.

Background and objective:    Drug abuse is one of the diseases that are highly dependent on individual behaviors and social interactions. This disease can be created in places like military garrisons due to their relationship with such behaviors. Therefore, soldiers and staffs are at risk of drug abuse. The aim of this study was to determine the effect of prevention training program of drug abuse on reducing risk factors in soldiers and staffs in Iran.Methods:In this quasi-experimental interventional study, 392 soldiers and staffs in two military garrisons in Khorasan Razavi (Intervention group 242 and control group 150) were randomly conducted to training program. The data collection tools were questionnaire of identifying people in risk of addiction, life skills questionnaire and demographic variables. The questionnaires were completed as self-report. Educational content was consisted of seven training sessions (60-minute) that only applied in the intervention group. 45 days after the last training session, educational software was distributed as a reminder in the intervention group. The two groups were followed up three months after the intervention. Finally, the data were analyzed using SPSS version 16.Results:  The findings showed that there was no significant difference between the two groups in demographic variables (Pvalue>0.05). The mean scores for risk factors on drug abuse after training program (Depression and feeling of inability, Positive attitude toward drug abuse and Anxiety and fearing of others) were significantly improved in the intervention group (Pvalue<0.05). Also, life skills variables except the problem solving skill (Pvalue>0.05) had a significant change after intervention in the intervention group (Pvalue<0.05).Conclusion:The findings indicated that the prevention training program of drug abuse based on life skills training could reduce the risk factors of drug abuse for soldiers and staffs in military garrisons.

In an effort to increase perceptions of cohesion among intercollegiate soccer players, a team-based mindfulness meditation program was undertaken. This team-building program was delivered by using a personal-disclosure mutual-sharing approach. A total of 31 female intercollegiate soccer players from two teams participated. Assigned to the intervention condition was a Canadian intercollegiate team (U Sports), while the control condition was an American intercollegiate team (NCAA, Division II). The participants completed a measure of cohesion (Group Environment Questionnaire) pre- and postintervention. Controlling for the preintervention scores, the 8-week team-based mindfulness meditation program resulted in significantly higher perceptions of social cohesion for the intervention group compared with the control group at postintervention. However, there were no significant differences in task cohesion between the intervention and control groups at postintervention. Using personal disclosure, mutual sharing seems a viable approach by which to deliver a team-based mindfulness meditation program to enhance a team’s social cohesion.

This study investigated the effects of a 24-week combined training program (CTP) based on strength exercises and cognitive–motor tasks performed concurrently in participants with multiple sclerosis. A randomized, controlled intervention study was carried out. In total, 31 subjects with a confirmed diagnosis of multiple sclerosis (14 men and 17 women) were stratified and randomized into an intervention group (17 subjects) and a control group (14 subjects). The intervention group completed three weekly training sessions for 24 weeks, while the control group pursued their normal daily activities. In this program, cognitive–motor tasks were completed at once (dual tasking). A 3D photogrammetry connected to a selective attention system designed for dual tasking while walking was used. Ground reaction forces were measured using two force plates, one for sit-to-stand testing, while the other was used for static force measurement. Postural equilibrium was examined using a stabilometric plate based for Romberg test assessment. The 24-week training program for multiple sclerosis patients improved their static peak force by 11% (p < 0 .05), their rate of force development by 36% (p < 0.05), and their balance (p < 0.05). Performance in daily activities such as walking or sitting-to-standing improved significantly in multiple sclerosis participants. CTP training was effective in reducing the dual-task costs of step length (48%) and walking velocity (54%), as compared to a matched control group.

AbstractThe goal of this study was to assess the effects of a supervised slackline training program in a group of soccer players. Thirty-four male division I under-19 players (16.64 ± 0.81 years) agreed to participate in the study. They were randomly divided into an experimental group (EG) and a control group (CG). The first group (EG) followed a 6-week supervised slackline training program (3 sessions/week; 5-9 min/session), while the CG performed only regular soccer training. Several variables were assessed in all participants: acceleration (20-m sprint test), agility (90º turns test), jump performance (squat jump, countermovement jump), and postural control (Center of Pressure ( CoP) testing: length, area, speed, Xmean, Ymean, Xspeed, Yspeed, Xdeviation, Ydeviation). Ratings of perceived exertion and local muscle ratings of perceived exertions were also recorded after each slackline training session. At post-tests, there was a significant increase only in the EG in acceleration, agility, squat jump and countermovement jump performance, as well as several CoP variables: area in the bipedal support on a firm surface, and length, area and speed in the left leg on a firm surface. The program was rated as “somewhat hard” by the players, while quadriceps, gastrocnemius and tibialis anterior were the most exerted muscles while slacklining. In conclusion, slackline training can be an effective training tool for young, high-level soccer players.
