  El objetivo de esta investigación fue valorar los efectos de distintos tipos de calentamientos aplicados en escolares sobre la calidad de movimiento de las habilidades motrices y el rendimiento de salto y carrera. La metodología utilizada fue a partir de un diseño estudio cruzado aleatorizado (n=27 escolares), que incluyó tres condiciones experimentales para valorar el efecto agudo de distintos tipos de calentamiento (tradicional, basado en juegos adaptados reducidos y FIFA 11+) sobre el salto vertical, sprint en 20 metros y habilidades motoras de locomoción y control de objetos en niños y niñas. Se utilizó estadística descriptiva y comparativa a través de ANOVA de medidas repetidas y Friedman con sus pruebas post-hoc según corresponda. Los resultados muestran que todos los tipos de calentamiento mostraron diferencias significativas en sprint, salto vertical y habilidades motoras, respecto al a la condición control sin calentamiento. El calentamiento basado en juegos adaptados reducidos presentó efectos superiores que las otras modalidades en las habilidades motoras de locomoción (p< .05). Las comparaciones entre calentamientos mostraron que la intervención basada en FIFA 11+ mostró ser más eficaz en reducir el tiempo de sprint en 20 metros y aumentar la altura del salto vertical (p< .05). En conclusión, este estudio sugiere que, la selección de una estrategia adecuada basada en una diversidad de experiencias motrices como las ofrecidas por los protocolos de calentamiento FIFA11+ y de juegos adaptados reducidos podría ser clave para mejorar el rendimiento motor y la magnitud de los beneficios asociados al calentamiento.  Abstract: The objective of this research is to assess the effects of different types of warm-ups applied in schoolchildren on the quality of movement of motor skills and jumping and sprint performance. The methodology used was based on a randomized crossover study design (n = 27 schoolchildren), which included three experimental conditions to assess the acute effect of different types of warm-up (traditional, based on reduced adapted games and FIFA 11+) on the vertical jump, sprint in 20 meters and motor skills of locomotion and control of objects in children. Descriptive and comparative statistics were used through repeated measures ANOVA and Friedman with its post-hoc tests as appropriate. The results show that all types of warm-up showed significant differences in sprint, vertical jump and motor skills, compared to the control condition without warm-up. The warm-up based on reduced adapted games presented greater effects than the other modalities on the motor skills of locomotion (p <.05). Comparisons between warm-ups showed that the intervention based on FIFA 11+ was shown to be more effective in reducing sprint time by 20 meters and increasing vertical jump height (p <.05).  In conclusion, this study suggests that the selection of an appropriate strategy based on a diversity of motor experiences such as those offered by the FIFA11 + warm-up protocols and reduced adapted games could be key to improving motor performance and the magnitude of the benefits associated with warm-up.

This study aimed to assess the effects of repeated menthol mouth swilling upon strength and power performance. Nineteen (10 male) participants completed familiarisation and experimental trials of repeated menthol mouth swilling (0.1% concentration) or control (no swill) in a randomised crossover design. Participants performed an isometric mid-thigh pull (IMTP; peak and mean force; N), vertical jump (peak; cm) and six second sprint (peak and mean power; W) under each condition. Participants completed three efforts per exercise task interspersed with three-minute recoveries. Mean best values were analysed via a two-way mixed repeated measures ANOVA, and differences reported as effect sizes ± 95% confidence intervals, with accompanying descriptors and p values. Differences in peak IMTP values were unclear between familiarisation and experimental trials, and between menthol and control conditions. Mean IMTP force differed between familiarisation and control (0.51; −0.15 to 1.14; p = 0.001) and familiarisation and menthol conditions (0.50; −0.15 to 1.14; p = 0.002) by a small degree, but were unclear between control and menthol conditions. Unclear differences were also noted on vertical jump performance compared to familiarisation and between experimental conditions, with repeated six second peak and average power performance also showing unclear effects across all comparisons. We conclude that repeated menthol mouth swilling does not improve strength or power performance.

Although warm-up and stretching exercises are routinely performed by gymnasts, it is suggested that stretching immediately prior to an activity might affect negatively the athletic performance. The focus of this investigation was on the acute effect of a protocol, including warm-up and static and dynamic stretching exercises, on speed during vaulting in gymnastics. Eleven boys were asked to perform three different protocols consisting of warm-up, warm-up and static stretching and warm-up and dynamic stretching, on three nonconsecutive days. Each protocol was followed by a “handspring” vault. One-way analysis of variance for repeated-measures showed a significant difference in gymnasts’ speed, following the different protocols. Tukey’s post hoc analysis revealed that gymnasts mean speed during the run of vault was significantly decreased after the application of the static stretching protocol. The findings of the present study indicate the inhibitory role of an acute static stretching in running speed in young gymnasts.

INTRODUCTION: The enhancement of nurses’ risk perception plays a significant role in their preparedness during disasters and emergencies. Therefore, this study aimed to investigate the effect of educational workshops on disaster risk perception in nurses METHODS: This randomized controlled field trial study included 62 nurses working at Razi Hospital, Birjand, Iran. The participants were divided into intervention and control groups. The intervention group was then requested to participate in a one-day intensive educational workshop based on the current national standards. The workshop content included a combination of lecturing methods, round-table exercises, and film display. The data were collected using the demographic characteristic form and researcher-made questionnaires measuring the nurses’ risk perception during disasters and emergencies. Subsequently, the data were analyzed using independent t-test, repeated measures analysis, and Bonferroni post hoc tests. FINDINGS: The mean total score of risk perception were significantly higher in the intervention group before, immediately, and two months after the workshop session, compared to those in the control group (P˂0.001). CONCLUSION: The implementation of nurses’ national preparation program during disasters and emergencies can result in an increase in the nurses’ risk perception during these events. Therefore, regarding the importance of nurses’ preparedness in confrontation with disasters and emergencies, it seems necessary to integrate the National Preparedness Program into the educational programs immediately after recruitment and in the form of in-service courses.

Jumping and balance are necessary skills for most athletes, and mini-trampoline training has been shown to improve them. Little is known about the acute effect of mini-trampoline jumping on jump performance and dynamic balance. Objectives: The purpose of this study is to investigate the effect of 6 maximal jumps on a mini-trampoline on countermovement vertical jump (CMVJ) variables and on balance parameters. Methods: Twenty one recreationally trained individuals participated in three testing sessions and were either allocated to a control group (N=10) or a trampoline group (N=11). All the participants performed a dynamic warm up prior to their assessments. Baseline CMVJ and balance assessments were measured. For the jump performance tests, the control group rested for 30s, and the trampoline group performed 6 maximal CMVJs on a mini-trampoline. Immediately following the trampoline jumps or the rest period, participants performed three jump trials. The jumping protocol was repeated every minute up to 5 minutes and balance was reassessed immediately after only. Results: There was no significant interaction of time by group and no group effects in all the jumping parameters, however, there was a significant increase in jump height (p <0.001) post-condition, and a significant decrease in peak power (p= 0.01) at the 4th minute for both groups. There was no significant interaction of time by condition, no time effect and no group effect (p>0.05) on the balance variables. Conclusion: These results do not support our hypothesis and show that trampoline jumping does not improve jump and balance performance acutely.

This study aimed to determine the influence of concurrent training and athletic capoeira levels of motor performance in children aged 7 to 10 years indoor football. Study participants were children (n = 39) were male. The subjects were divided into two groups, submitted to concurrent training, the AF group (n = 20) underwent the training of soccer and athletics and FC group (n = 19) soccer and capoeira. To study and evaluate the level of motor  performance of the two sample groups, we applied a battery of tests for statistical analysis and checked the normality of the data (Kolmogorov-Smirnov) and applied repeated measures ANOVA with post hoc Bonferroni. We used the statistical packages SPSS (12.0) and Instat (3.0). The results note that in terms of motor proficiency children who practiced FC compared to  children who practiced FA had equal values in the components of motor skills, however, both groups showed a trend in weight gain in their motor skills.

AbstractBackgroundSex dialogue is one of the most critical and challenging topics between mothers and adolescents. The knowledge and skills of mothers in sex dialogue with their daughters are essential. The purpose of this study is to determine the effect of group counseling based on communication skills on mothers through their sex dialogue with their daughters.MethodsA randomized controlled field trial was conducted on 168 couples of mothers and their daughters selected by the stratified matching method and randomly divided into two control and intervention groups. The mothers in the intervention group participated in a communication-based consultation in groups consisting of 6–12 people for 6–7 weekly sessions, each one lasting 60 min. The data collection tool was a Persian-translated questionnaire by Jaccard for sex dialogue between mother and daughter. The data were analyzed using Chi-square (χ2), ANOVA with repeated measures and modified post hoc Bonferroni tests.ResultsThere was a significant difference in the mean score of mother-daughter sex dialogue 1 week after intervention between the intervention (34.48 ± 8.74) and control (40.44 ± 9.49) groups (p = 0.001) and 1 month after the intervention between the intervention (30.41 ± 10.07) and control (42.47 ± 9.62) groups (p < 0.001).ConclusionThrough applying communication skills, an increase in mother-daughter sex dialogue frequency was observed after group counseling. Therefore, it is suggested to promote mother-daughter communication skills by accessing the mothers via schools, health centers and with the aid of midwifery counselors, midwives and other trained caretakers.

Objective:The purpose of this study was to determine whether tasks involving effortful attention would cause augmentation of rigidity in patients with mild Parkinson disease.Methods:In 17 subjects with mild Parkinson disease, rigidity in a single arm was assessed during various experimental conditions by a blinded movement disorders neurologist. Rigidity was scored separately at the wrist and the elbow using an ordinal scale. In three of the conditions, sustained attention was directed toward visual, auditory or movement-related stimuli. Two varieties of Froment maneuver served as positive controls: contralateral hand opening-closing or ipsilateral foot tapping. In addition, rigidity was assessed twice with subjects resting. The examiner was unaware of the sequence of experimental conditions and this was changed for each subject. Mean rigidity scores for the various experimental conditions were compared against the baseline state (an average of both trials with the patient resting) using a repeated measures ANOVA and post-hoc Tukey-Kramer multiple comparisons test.Results:Rigidity was significantly increased from baseline with each of the attentional tasks (p <0.01 to p <0.001) and also with the two Froment maneuvers (p <0.001). Rigidity augmentation with contralateral hand opening-closing was significantly greater than with any of the attentional tasks (p <0.05 to p <0.001).Conclusion:Tasks of effortful attention did appear to augment rigidity in patients with mild Parkinson disease. We speculate that the greater augmentation seen with the Froment maneuver could have an anatomic basis.

Abstract The study aim was to compare the effects of a 7-week plyometric, strength and change of direction (COD) training program on basketball-specific performance measures in high-school players. Forty male players were randomly assigned to one of the four groups: plyometric (PG, n = 10), strength (SG, n = 10), COD (CODG, n = 10), and control group training (CG, n = 10). Two training sessions were performed at weekly intervals before basketball training. Performance of the counter movement jump (CMJ), Abalakov jump (ABKJ), 10 m zig-zag sprint, 20 m in line sprint (measurements at 10 and 20 m), and sit and reach flexibility test (SRFT) was assessed before and after the intervention. A 4 (group) × 2 (time) repeated measures analysis of variances (ANOVA) was conducted for each variable. Bonferroni post-hoc tests were used when the interaction was significant. Significant (all p < 0.05) time x group interaction was noted for SRFT, CMJ, ABK, sprint, and zig-zag 10 m, in favor of the experimental groups compared to the control group. However, improvements in physical fitness were similar between the three experimental groups. In conclusion, 7 weeks of specific plyometric, strength and COD training produced similar medium to large improvements in physical fitness of high-school basketball players.

Research background. Stretching is believed to enhance performance, reduce injury, and be an effective means of developing flexibility and alleviating muscular soreness (Shellock, Prentice, 1985; Brandy et al., 1997). A review of the current literature shows that the results of many studies conflict with others; some report that static stretching diminishes vertical jum (VJ) performance (Cornwell et al., 2001; McNeal, Sands, 2003; Wallmann et al., 2005), whereas others report that static stretching has no effect at all on VJ (Church et al., 2001; Power et al., 2004; Unick et al., 2005). Research aim, was to examine the effects of different durations of stretching on performance and to find the stretching durations that affect the performance negatively or positively. Research methods. The subjects of the study were 27 rhythmic gymnasts with the mean age of 10.00 ± 1.2 years. The subjects as a whole group participated in two different stretching programs on nonconsecutive days to eliminate the effect of individual differences on the performance. On the first day, athletes were asked to warm up by 5 minute jogging after the pretest was administered. The posttest measured the vertical jump performance after athletes stayed inactive for 20 minutes. They rested for a day and on the third day, their performance was measured again. After the 5 minute warm-up period, 10 repetitions of 15 seconds static stretching exercises for hip flexor, hamstring and gastrocnemius muscle groups were followed by the posttest. Moreover, on the fifth day 30-second exercises were repeated five times on the same type of muscles. The participants in this investigation were tested in individual vertical jump performances following warm-up only, warm-up plus 15 seconds static stretching, and warm-up plus 30 seconds. Research results. Results of a one-way repeated-measures ANOVA indicated a nonsignificant difference for vertical jump performance (F = 2.052; p > 0.05). Discussion and conclusions. Stretching exercises are referred in rhythmic gymnastics more intensively than other sports. Relevant literature displays fewer stretching repetitions and durations. These durations and repetitions may not be realistic and practical for rhythmic gymnasts. Therefore, the durations and repetitions utilized in this study are considered more appropriate for rhythmic gymnastics trainings. Rhythmic gymnasts may make use of duration and repetitions determined in this study that will not affect their performance.Keywords: anaerobic power, gymnastics, exercise.

Aim: To examine the effects of coordination applied to 8-10 years old female athletes on tennis and some motor skills. Metodology: The athletes were randomly divided into experiment and control groups by applying Dewitt-Dugan tennis test, standing long jump, vertical jump, 20m speed, T test and square test. In the study, while the control group only participated in club training for 8 weeks, 5 days a week and 60 min.and the experimental group added coordination training education. Data was collected and entered in SPSS 22.0. Results: There was a significant difference (p<0.05) in the parameters of all measurements of the experimental group in the standing long jump, vertical jump, 20m speed, t test and Dewitt-Dugan parameters and no significant change in the square test results (p>0.05). Among the final measurement values of the experimental and control groups, significant differences were found in favor of the experimental group in the values of standing long jump, vertical jump, 20m speed and Dewitt-Dugan parameters, except for the T test and the square test (p<0.05). Conclusion: It can be said that the 8-week coordination training applied to the experimental group has a positive effect on the motor characteristics and tennis skill, and specific coordination movements added to each unit training can be beneficial for the athletes.
