The Effects of Brazilian Jiu-Jitsu on Body Composition, Health Fitness, Functional Movement Screening in non-Elite Healthy Young Adults

OBJECTIVES Brazilian Jiu-Jitsu (BJJ) has grown massively in recent years, but its positive effects in non-elite population has not been analyzed. The purpose of current study was to exam the effects of BJJ on body composition, health fitness components, and functional movement screening (FMS) in healthy young adults.METHODS Combined exercise program was composed of aerobic and resistance exercises. All participants were randomly assigned either into BJJ exercise group (BJEG, n=10, 28.10±2.64 years) or combined exercise group (CEG, n=10, 28.20±3.43 years). Exercise intervention was conducted for ninety minutes per session, three times per week for twelve weeks.RESULTS Body fat (%) and muscle mass (kg) were significantly improved in both groups. Muscle strength in upper and lower extremity, muscle endurance, flexibility, power were significantly improved in both groups. Cardiorespiratory fitness in BJEG was significantly improved. Also, FMS total score and deep squat score showed significant improvement in both groups.CONCLUSIONS BJJ is an effective exercise for health and fitness management purpose in non-elite healthy young adults.

Big Data and Deep Learning Model for FMS Score Prediction of Aerobics Athletes

In recent years, competitive aerobics has developed rapidly in my country, and the corresponding sports injury risks have gradually increased. A number of studies have shown that due to the characteristics of aerobics itself, difficult movement requirements, fast-paced music accompaniment and coherent coordinated movements, athletes will suffer sports injuries if they are not paying attention. Therefore, discovering the causes of athletes’ injuries in time and preventing them in time is crucial for improving athletes’ skill level and prolonging sports life. Through the functional movement screening (FMS) test, understanding young aerobics athletes’ insufficiency in trunk stability, joint flexibility, muscle extension, and core strength can further help athletes reduce the risk of sports injuries. Therefore, this article proposes a novel sports injury risk model based on big data technology and deep learning, which can effectively predict the risk of sports injury and can play a positive role in improving the quality of athletes’ movements and prolonging their sports life.

Comparison of Motion Control Screening Test Scores in Active Women with a History of Knee and Ankle Injuries

Objective: Commenting on the return to sport after some injury is in doubt. The aim of this study was to investigate the relationship between test scores of movement control and a history of knee and ankle injury in active females. Methods: Statistical population of this study was 57 active females (22 healthy subjects, 19 subjects with a history of previous knee injury and 16 subjects with a history of previous ankle injury) with age ranging from 18 to 25 years old. In order to evaluate subjects, were used to the movement control test set consists of nine separate questions. Total maximum points in the subtests were 40 points, which less point was a better result in these tests. For statistical analysis, Kolmogorov-Smirnov test, Levene test, analysis of variance (ANOVA) and Tukey test were used (Significant at 95% and the alpha less than or equal 0.05, and using of the SPSS software v. 22). Results: The results of this study showed test scores of movement control earned by females with a history of ankle and knee injuries was significantly different with the healthy females (P=0.001).Compare scores of subjects with contact and non-contact injuries with healthy women showed that contact injury had higher scores than those who are non-contact injuries. The differences between the groups with any of these injuries are significant with no injury group (P=0.001).Cut-off point for this test was about 15.5. Conclusion: The scores of functional movement screening give a detailed model of the injury prevention to coaches in order to predict the risk of lower extremity injuries in athletes. So its need to coaches in order to the prevention of sports injuries, use the functional movement screening tests. To measure the performance level of the athletes before the start of the season, in order to identified athletes that are at risk of injury, in order to improve their capabilities.

Utility of preinduction tests as predictors of attrition in infantry recruits: a prospective study

IntroductionInfantry recruit attrition wastes resources and can affect combat readiness. The purpose of this study was to examine the utility of preinduction tests as a predictor of attrition among conscripts in the first year of infantry training.Methods303 infantry conscripted recruits participated in a prospective study. Before their service, recruits received health profile and Quality Group Scores (QGSs). Recruits were screened at induction using questionnaires, by functional movement screening (FMS) and by upper and lower quarter Y-balance, dynamic and anthropometric tests. They were followed for musculoskeletal injuries and attrition during the first year of training.Results165/303 (54.5%) recruits were diagnosed with musculoskeletal injury or pain during the first year of their training. 15.2% did not complete their first year of service as combatants and 5.9% were discharged. On multivariable binary stepwise logistic regression analysis for attrition, protective factors were higher QGSs (OR 0.78, 95% CI 0.69 to 0.89) and recruits diagnosed with musculoskeletal injuries or pain (OR 0.20, 95% CI 0.09 to 0.48). Pain in the balance test performed at the beginning of training was a risk factor (OR 3.31, 95% CI 1.44 to 7.61). These factors explained only 15.4% of the variance in attrition.ConclusionsFMS was not a significant predictor of infantry attrition. Measuring the three variables found to be associated with infantry attrition would seem to be valuable when the number of infantry candidates greatly exceeds the number of infantry positions. Transferring infantry attriters to non-combatant roles and not discharging them is a way to manage the problem of attrition.

Functional Movement Screening: A study on National Level Judo Players of Pakistan

Background: Functional Movement Screening (FMS) is a tool to screen the musculoskeletal factors of injury or dysfunctionality patterns in sports. The establishment of functional movement screening (FMS) has built a bridge between physiotherapy, rehabilitation, and physical training, to realize the integration of multiple disciplines. This study tends to investigate musculoskeletal risk factors through the FMS of Judo players in Pakistan. Method: A total of 10 national-level athletes were selected who had been national-level competitors in Pakistan. Different movement patterns/drills prescribed by FMS were performed by them under a secure environment. These movement patterns were designed to provide observable performance of basic locomotor, scheming, and stabilizing movements by putting a person in severe positions where weaknesses and imbalances become noticeable if proper movement and motor control are not utilized。FMS score sheet was used for marking along with total scores of all drills. Conclusion: Results showed that the majority of the Judo athletes were found under standardized grading out of whom only three players were able to get marked above 16 out of 21. Athletes were unaware of FMS and the majority of athletes failed to perform FMS drills which caused them problems in their balance, flexibility, and agility.

The Relationship Between Functional Movement Screening With Fitness Factors in Female Athlete Students

Objective: The study examines the relationship between Functional Movement Screening (FMS) tests with fitness factors in female athlete students. Methods: The study population includes 30 female athlete students (Mean±SD of age: 23.36±3.10; height: 163.45±5.06; and 57.40±6.43). FMS test was used for measuring movement patterns. Sargent test was used to measure lower limb power, Y-test was used to measure dynamic balance, Stork test was used to measure static balance, and flexor/extensor muscle endurance tests were also used to measure trunk muscle endurance. In addition, Pearson correlation was used to evaluate the relationship between scores of functional motion screening and fitness factors. Multivariate regression was used to solve the linear regression equation. The data analyzed in SPSS software, V. 22 at significance level of P≥0.05. Results: Our results showed no significant relationship between FMS test with fitness factors (P>0.05). Conclusion: There is no significant relationship between total score of FMS test with fitness factors. It seems that FMS addresses the quality of basic motor activities while fitness factors determine sport skills; thus, FMS scores can’t explain fitness factors.

Relationship between functional movement screening and static balance scores: Increasing the educational level of elite female wrestlers

The importance of balance is considerably high in many sports that require struggle and close contact such as wrestling. Some losses in maintaining the balance due to the movements requiring high intensity during competitions and increase in the risk of injury due to these losses may occur in wrestling athletes. The aim of this study is to Increase the educational level of elite female wrestlers by examining the relationship between Functional Movement Screening Test Scores and static balance performance scores of elite young female wrestlers. 19 elite female wrestlers having average age of 22.94 ± 2.67 years, body weight 61.63 ± 7.25 kg, height 165.37 ± 5.17 cm and BMI 22.46 ± 1.60kg / m2 participated in the study. Functional Movement Screen Test ™ (FMST™) battery was used in determining the functional movements of the participants, while Tecnobody Prokin 200 Bergamo/Italy was used to determine the total postural stability index values. All static balance measurements were evaluated as standing Double-Leg Eyes Open (DLEO), Eyes Open Single-Leg Dominant Non-Dominant (EOSL-DM and EOSL-ND). Since higher stability index values indicate lower stability, the participants were found to have a negative correlation between non-dominant leg static balance and HS. SM. and TSPU, and between dominant leg static balance and HS. SM. and TSPU. In addition, it was found out that, there was a negative correlation between non-dominant leg static balance, dominant leg static balance and double leg static balance and the FMST™ scores of the participants. The results of this research can be very effective in improving the educational process in the field of wrestling.

Effect of battle rope training on functional movements in young adults

Introduction and Aim: The battle rope exercise had obtained highest peak and mean VO2, highest energy expenditure and highest exercise heart rate than other exercises. There is no related evidence for Battle rope exercises by screening functional movement. The aim of the study was to determine the effect of battle rope training on functional movement screening. Methodology: According to inclusion and exclusion criteria 30 subjects were selected. They were explained about the safety and simplicity of the procedure and by the lottery system they were divided into two groups with 15 subjects in each group. Each subject has undergone pre-test and post-test measurement of functional movement screening (FMS). Group A participants did regular set of floor exercises like pelvic bridging, bird dog exercise, cat and camel exercise for 4 weeks. Group B participants did pelvic bridging, bird dog exercise, cat and camel exercise and battle rope training for 4 weeks. The data collected and tabulated, were statistically analysed. Functional movements: 7patterns of functional movements include deep squat, hurdle step, inline lunge, rotary stability, active straight leg raise, shoulder mobility, and trunk stability push-up. Results: The result of this study were statistically significant in FMS pretest and posttest with the p values (p<0.0001). Between the posttest mean and standard deviation of FMS of both group A and group B are 14.53(2.78), and15.43 (2.60) respectively. And there was a significant difference among the values (p >0.0001). Conclusion: This study concludes that battle rope training is better than traditional floor exercises in improving functional movements among young adults because of its simulation of functional movement patterns.

Assessing the sport-specific and functional characteristics of back pain in horse riders

Currently, no standardised screening tools nor established interventions are available to address the characteristics of back pain (BP) specifically in horse riders. Therefore, the aim of this case-control study is to explore sport-specific and functional characteristics of BP in horse riders. 16 professional and 16 amateur riders (25±7 years) participated in two questionnaires (a sport-specific questionnaire and the Oswestry Disability Index questionnaire) and were examined via the physical functional movement screening (FMS) and Luomajoki’s motor control (MC) screening. The lifetime prevalence of BP was as high as 81%, and spinal discomfort in horse riders was mainly located in the lumbar spine. Professional riders revealed significantly higher prevalence of BP in the last month before assessment (P=0.014) than amateur riders. Compared to horse riders using dressage or multiple saddle types, show jumping riders (n=10) who only use jumping saddles (P=0.027) also revealed higher BP prevalence. Horse riders with lower scores on the FMS and MC screening, and thereby with more movement dysfunctions, were found to experience higher levels of pain (r=-0.582, P=0.001; r=-0.404, P=0.024, respectively) and disability caused by BP (r=-0.688; P<0.001; r=-0.474; P=0.006, respectively). Both physical screening tools are found to be clinically relevant enabling investigators to identify objective functional characteristics related to BP in horse riders. The high prevalence of BP in riders is a clinically important finding that should be explored further to elucidate the causes and subsequently guide occupational health in horse riders.

Functional Movement Screening: An Early Detection of The Student Injury Risk in Sport Class

Physical Education class is one of the solutions taken by regional schools to improve achievements in sports. The process of recruiting physical education class students has mostly conducted by using the talent scouting test method which consists of physical test and skill test. However, the implementation of sport injury detection test using Functional Movement Screening (FMS) is still insignificant. The purpose of this study was to identify the student risk of injury in physical education class by using the FMS test. The research was an ex-post-facto method. The research samples were 32 students of class VIII in the physical education class at SMPN 1 Baturaden (20 males and 12 females) aged 14 years in average. The research instrument used was the Functional Movement Screening (FMS) test with the validity and reliability of 0.81. Data processing and analysis employed the Benchmark Reference (PAN) with the help of Ms. Excel. The results showed that 56.25% of physical education class students at SMPN 1 Baturaden were identified at risk of sports injuries. The results also showed an imbalance of strength between the right and left body muscles. The study concludes that the use of Functional Movement Screening (FMS) test is important to minimize the high likelihood of injury of the students in physical education class.
