Background: Insole orthotics are prescribed to correct human body position during both the standing position and the motion of gait. Also, they are being applied for people who have forefoot abduction and arch deformation. However, a little is known about the relationship between forefoot and arch orthotic correction and the alternation in foot biomechanics. Objectives: This study was aimed to determine the effect of non-prescription insole orthotics in walking gait parameters. Methods: It was a quasi- experimental with pre-test, post-test design study. Twelve volunteer participants (41 ± 17 y), 10 men and two women, participated in this study. Three-dimensional (3D) cameras were used to do motion capture through those markers placed on lower body segments. Seven segments such as: Hip, left and right thigh, left and right shank, left and right foot were used for labelling in this study, which was measured with Vicon T-Series cameras at 250 Hz. The participants did walk in three different phases: Barefoot, running shoe, running shoe with a non-prescription orthotic inside. t-test was used to analyse the data. Results: The paired t-test results indicated that there is significant difference in cadence, step length and stride length for running shoe, and non-prescription orthotics compare to those of barefoot (P ≤ 0.05). Additionally, it was found that, non-prescription orthotics resulted in higher step length and stride length, and less cadence (P ≤ 0.05). On the other hand, But, no significant changes were found for non-prescription orthotics (P ≥ 0.05). Conclusions: It was concluded that cadence, step length and stride length were improved in running shoe compared to non-prescription orthotics group. But there were not any significant differences between running shoe and non-prescription orthotics.

Background: Researchers believe the beneficiary role of some supplements in improving futsal player's performance, since their performance is disturbed by lactate accumulation. Objectives: In the present study, we aimed to investigate the acute effects of high-carbohydrate and high-caffeine drinks on the motor performance (speed and coordination) and cognitive function of futsal players. Methods: The study utilized a quasi-experimental design with a pretest-posttest control group. The study involved 40 participants who were randomly assigned to one of four groups: (1) carbohydrate supplementation (N = 10), (2) caffeine supplementation (N = 10), (3) carbohydrate and caffeine supplementation (N = 10), and (4) control group (placebo). The subjects were given two different sports drinks, one containing carbohydrates and caffeine, each at a dose of 6 mL per kilogram of body weight, while the control group received a placebo. To measure speed, a 36-m sprint test was used, while coordination was assessed using a dribble and shoot test. Cognitive performance was measured using a modified version of the continuous performance test (CPT) developed specifically for use with futsal players. Results: The study found that carbohydrate intake had a significant positive effect on reaction time and coordination (P < 0.05). Caffeine intake was also associated with a significant improvement in cognitive performance (P < 0.05), but no significant effect was observed on speed and coordination (P > 0.05). Furthermore, the group that received both carbohydrate and caffeine supplements showed improvements in speed, coordination, and cognitive performance (P < 0.05). Conclusions: It is suggested that taking a supplement containing a combination of carbohydrates and caffeine for 5 days prior to performance may lead to improved results in speed and coordination tests.

Background: The purpose of the present study was to assess the impacts of plantar-flexors and dorsi-flexors fatigue following isokinetic contractions on postural control in nine young healthy national level judo athletes. Methods: Participants were required to stand still on a force plate with opened and closed eyes in feet together (FT) and single leg (SL) stance before (PRE) and after (POST) an isokinetic fatigue protocol. Mediolateral sway (ML sway), anteroposterior sway (AP sway), and velocity sway were calculated and used to assess the postural control. Results: Velocity sway POST was significantly (P < 0.001) higher than PRE in FT stance and SL stance. Velocity sway POST was significantly higher in the SL stance than the FT stance (P = 0.01). During eyes closed, a significant interaction postural task by fatigue for all parameters was found. All parameters increased significantly after fatigue compared to PRE. After fatigue, ML sway, AP sway, and velocity sway were significantly higher for the SL stance than the FT stance. Conclusions: Ankle muscle fatigue led to reduced postural stability during different stances in young healthy judo athletes. This effect was more accentuated when vision was removed and the base of support was reduced. Alteration of postural control depended on the difficulty of the postural stance.

Background: Recent research indicates the prevalence of vitamin D deficiency worldwide and is conflicting evidence as to whether vitamin D supplementation actually improves physical performance. Objectives: The purpose of this study was to investigate the effect of vitamin D supplementation on improving muscle strength, muscle volume and cardiorespiratory fitness through resistance training in male athletes with vitamin D deficiency. Methods: This study was conducted with pre-test and post-test series design and quasi-experimental method. The population included 36 male futsal players with vitamin D deficiency that were randomly divided into four groups of nine: exercise (EX), exercise-supplement (EXS), supplement (SUP) and control (CON). SUP and EXS groups received vitamin D3 (50,000 intramuscular injections) every two weeks for 8 weeks and performed three resistance training (RT) sessions per week at a rate of 75% 1RM. Before and after intervention, blood sampling were drawn and measurements performed for 1RM, muscle volume (cm2), and VO2max by standard Bruce test. Correlated t-test was used to compare pre-test and post-test results and to measure the differences between groups, one-way analysis of variance and LSD post hoc test were used using SPSS statistical software. Results: Muscle volume increased significantly (P-value = 0.001) only in EX and EXS groups. Cardio-respiratory fitness did not change significantly in any of the groups (P > 0.05). There were no significant differences between EXS and SUP groups for any of the measured variables (P ≥ 0.05). Conclusions: It seems that simultaneous application of vitamin D supplementation and resistance training for 8 weeks does not have a significant effect on the improvement of the strength and endurance of futsal players.

Background: Intrinsic and extrinsic motivational factors can affect the levels of adherence of physical activity (PA) during the aging process. Objectives: Investigate the intrinsic and extrinsic aspects and motivation that led older women to enroll in and adhere to a community PA program before the COVID-19 pandemic. Methods: Data were collected via transversal survey before the COVID-19 pandemic. The sample consisted of 21 women, participants of a PA workshop, aged between 60 to 86 years [< 1-year (n = 8) and ≥ 1-year (n = 13) groups]. Motivation was assessed by the Motivation Inventory for Regular Physical Activity Practice (IMPRAF-54), using the 60th percentile to categorize high and low motivation, and two open questions. For qualitative assessment, content analysis was used and the answers were framed into subcategories regarding the motivation factors for adherence and permanence. Results: That adherence to the program was motivated by sociability purposes [total score: 36.0 (6.0), median (interquartile range)] and pleasure [34.0; (6.0)], while the main motivation for permanence was health [40.0 (11.0)]. Differences were noticed between the groups for sociability [38.0 (3.0) P = 0.030] and competitiveness [9.50 (12.0); P = 0.037] highest medians for the < 1 year group. Furthermore, the factors that least motivated older women were competitiveness and aesthetics. Conclusions: Health and sociability were the main motivators for the practice of physical activity among older adult women. Motivation played a fundamental role in the permanence of older adult women in the physical activity program.

Context: A model of agility ladder tool was designed in the current study to increase cognitive-motor performance in athletes with more advantages over conventional agility ladders. Objectives: The aim of this study was to develop agility tool for athletes using Jami agility table (JAT) which has been the latest training model by creating mental challenge and recruiting muscle movement units for agile performance of sports skills. Methods: In this descriptive-analytical study, a systematic review of agility development methods were presented to improve psychomotor performance in athletes and then the JAT agility table model was introduced. Based on the JAT, a special code is designed in order to develop agility both physically and mentally aspects, and athlete is always engaged with new algorithms of movement. Results: One of the exclusive functions of JAT, is to increase contextual interference in the performance of motor skills which increases reaction time (RT) in athletes significantly. Laterality detection and empowering non-dominant hemisphere is one of the applications of the JAT, which ultimately increases the comprehensive development of the central nervous system (CNS). Conclusions: The most important aspect of JAT is based on increasing contextual interference and random learning in learners and athletes. Additionally, neuromuscular coordination is one of JAT functions which would improve agility performance in athletes. JAT mechanism has been designed based on Movement algorithm models. In such a training model, which imposes a better cognitive function on the learner and athlete to create better motor memory, the process of constant algorithms is converted into variable and instantaneous algorithms, resulting in more reliable motor outputs.

Background: Emotional intelligence (EI) and emotional competence (EC) are considered as multidimensional strategies for dealing with various complex situations. There are conflicting results regarding the effect of age, gender and sports status on EI and EC dimensions. Objectives: In the present study, we compared the EI between young athletes and non-athletes, as well as in terms of both genders and different age groups Methods: Four hundred seventy-nine young individuals (239 athletes, 240 non-athletes) aged 12 - 18 years old participated in this study. They were classified according to their age (12 - 15 years and 16 - 18 years) and gender (239 male, 240 female). All participants completed the Profile of Emotional Competence (PEC); for assessing the intra- and interpersonal EC and global EI. Results: Athletes had significantly higher values of global EI and altogether the intra- and interpersonal EC dimensions (all, P < 0.001). The comparison between genre and age groups highlighted those males and younger participants showed significantly higher components for both inter- and intrapersonal EC and global EI than females and older participants respectively (0.05 < P < 0.001). Conclusions: Based on the result of the current study, we conclude that engagement and involvement in sports can be considered as a key factor for developing adequate EI. Psychologists and sport-scientists need to be aware about the specific-related psychological skills for both age and gender requirements, particularly EI.

Background: Volleyball is a sport with technical elements and explosive power. Objectives: This study investigates the relationship between sprint speed and isokinetic knee strength applied at different angular velocities in male volleyball players. Methods: This study was conducted on 15 volunteer male volleyball players (age; 17 - 25 years, height; 1.75 + 0.12 m). Isomedx 2002 isokinetic dynamometer is employed to measure the isokinetic strength, and a 20 m sprint test is conducted to measure the speed. In measuring knee flexion and isokinetic extension strength, quadriceps and hamstring concentric/eccocentric are measured separately on both legs at 60°/sec angular velocity for three repetitions, at 180°/sec for six repetitions, and at 300°/sec for nine repetitions. For statistical analysis, the Spearman’s correlation test was performed using SPSS 18.0 (SPSS Inc., USA) software. Results: The highest torque value in subjects was recorded on both sides at 60°/sec angular velocity, 180 and 300 degrees, respectively, were lower. There was no significant relationship between speed and isokinetic strength at different angular velocities. Conclusions: Based on our results, the highest peak torque in volleyball players was found to be at 60°/sec angular velocity while no significant correlation was found between isokinetic strength of the knee at different angular velocities and speed of volleyball players.

Isomedx 2002 isokinetic dynamometer is employed to measure the isokinetic strength, and a 20 m sprint test is conducted to measure the speed. In measuring knee flexion and isokinetic extension strength, quadriceps and hamstring concentric/eccocentric are measured separately on both legs at 60°/sec angular velocity for three repetitions, at 180°/sec for six repetitions, and at 300°/sec for nine repetitions. For statistical analysis, the Spearman’s correlation test was performed using SPSS 18.0 (SPSS Inc., USA) software. Results: The highest torque value in subjects was recorded on both sides at 60°/sec angular velocity, 180 and 300 degrees, respectively, were lower. There was no significant relationship between speed and isokinetic strength at different angular velocities. Conclusions: Based on our results, the highest peak torque in volleyball players was found to be at 60°/sec angular velocity while no significant correlation was found between isokinetic strength of the knee at different angular velocities and speed of volleyball players.","PeriodicalId":118920,"journal":{"name":"International Journal of Sport Studies for Health","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125469938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Vision, vestibular sense, proprioception and muscle strength are required to maintain balance. However, gender could also play a crucial role in postural sway. Objectives: This study was used to examine (i) the impact of gender, surface type, and vision on postural sway; (ii) the effects of gender and vision on the limb symmetry of postural sway; and (iii) to understand the effects of gender, stance, surface type and vision on the alterations of dynamic postural sway alterations. Methods: This was a cross-sectional study in which young, healthy men (n = 15) and women (n = 12) underwent a balance control assessment using a force plate (SATEL, 40 Hz). Postural stances were evaluated in different conditions: opened eyes (EO) and closed eyes (EC), on different surface foam vs. firm, a dominant leg stance (DL) vs. a non-dominant leg stance (NDL), and a mediolateral stance (ML) vs. an anteroposterior stance (AP). The mediolateral sway (ML sway), anteroposterior sway (AP sway), and sway area were calculated from the centre of pressure displacements. Results: ML sway, AP sway and sway area increased when eyes were closed (P < 0.000). Foam surface perturbs balance control more than firm surface under EO and EC conditions for both genders, as observed in the AP sway curve (P < 0.000). A functional symmetry exists between the DL and NDL for all sway parameters: the ML sway, AP sway, and sway area (P = 0.720; P = 0.292; P = 0.954). The AP stance is more stable for the ML sway than the ML stance for both genders (P < 0.001). For the AP sway, the ML stance is more stable than the AP sway AP direction stance for both genders (P < 0.001). Women were significantly more stable than men in the ML stance when vision was absent (P < 0.01). Conclusions: Postural sway was altered more significantly on a foam surface than on a firm surface and symmetry between the DL and NDL was observed. Furthermore, we concluded that women have better dynamic balance control than men.
