Anthropometric measurements and agility performance in amateur roller skaters: a correlational study

Background: Research on the body structure of roller skaters has identified that anthropometric attributes are desirable in this sport for a better performance. Leg length has a definite decisive advantage in sport. Explosive leg power is very essential for roller skating as it requires speed, agility and quickness which can be associated with lower limb muscle girth. Hence, it is important to examine the contribution of limb length, calf and thigh muscle circumference, to agility performance. Methods: 30 healthy amateur roller skaters within age group of 6 to 14 years were assessed for anthropometric measurements – lower limb length, thigh circumference, calf circumference measurement. Participants performed a standardized warm-up of moderate-intensity jogging (5-10 min), static and dynamic stretching (5 min) and brief bouts of high-intensity running, including changes in direction on the ground. They performed agility tests in order of Edgren side step test, t-test and Illinois agility test based on test direction, progressing from uniplanar movements to biplanar and concluding with multidirectional movements. Each test was performed twice with 1-minute rest period between each trial, and a 2 min rest period between each test. Results: Pearson’s correlation showed that lower limb length have a moderately positive correlation with agility (r=0.5-0.7) whereas calf and thigh muscle circumference have a strong positive correlation with agility (r=0.7-0.8) stating that anthropometric measurements have a statistically significant correlation with agility performance with p<0.05. Conclusions: Anthropometric measurements such as lower limb length, thigh and calf circumferences have a moderate to strong positive correlation with agility performances of healthy amateur roller skaters within the age group of 6-14 years..

Research progress on effects of wearable resistance training on lower limb movement ability / 中国组织工程研究

BACKGROUND:Superior lower limb mobility is regarded as one of the prerequisites for winning competitions.Wearable resistance training can effectively overcome the deficiency in the transfer efficiency of traditional strength training in enhancing lower limb mobility.Considering that the impact of wearable resistance training based on different body parts on lower limb mobility may have significant differentiated characteristics,it is particularly important to review and summarize the specific application strategies and acute and chronic intervention effects. OBJECTIVE:To comb and analyze acute and chronic intervention effects of wearable resistance training based on different body parts on lower limb mobility,in order to provide insightful and methodological references for optimizing application strategies for lower limb movement ability. METHODS:A literature search was conducted in CNKI,Wanfang,VIP,Web of Science,Medline,SPORTDiscus,and PubMed databases for publications up to October 2023.Chinese and English search terms were"arm,forearm,limb,leg,lower extremity,vest,trunk,resist,weight,load,sprint,agility,change of direction".A total of 60 articles were ultimately included for review after screening the retrieval results. RESULTS AND CONCLUSION:(1)Trunk loading of 6-20%of body mass is suitable for optimizing acceleration in sprinting,while trunk loading of≤6%body mass is suitable for optimizing high-speed running.A trunk load of 5%body mass is applicable for optimizing change-of-direction movement;forearm,calf,or thigh loading often uses 1%or 2%body mass.(2)Trunk loading optimizes the functional performance of the lower limb stretch-shortening cycle by increasing vertical load.This enhances the efficiency of ground reaction force utilization and strengthens the coordinated stability control of the whole body musculature.Forearm loading effectively enhances the driving force of the upper limb swing,improves the propulsive force of the lower limb sprint,and optimizes the efficiency of inter-limb coordination.Calf loading can impose restrictions on the function of the hip joint,thereby leading to localized load stimulation and compensatory functional enhancement in the knee or ankle joint.Thigh loading partially restricts the peak extension angle and speed of the knee joint,creates specific load stimulation at the hip joint,and significantly improves its rotational kinetic energy output.(3)During larger-angle change-of-direction movements,the impact of calf loading is more significant than thigh loading.Thigh loading stimulation helps to enhance power output,while calf loading stimulation aids in improving stability control and directional change.(4)Currently,wearable resistance training has been proven to be an effective way to improve sprint and change-of-direction performance.The methodological strategies to improve sprint performance are relatively mature,but the optimal application scheme to improve change-of-direction performance needs to be further refined and optimized.Further research is recommended to supplement this area.

IMPACT OF LEADER'S INVOLVEMENT IN AGILE MATURITY ASSESSMENTS

Agile is the way we look at things happening around us. Agile is a behavior pattern, how you look at the world's complex situations, how you react to situations, how you visualize a solution, how you reach the solution. You can either think of a complex problem or a situation and worry about it or you break that into meaningful small chinks & try to solve it. Agile adds that fun element of tackling smaller challenges systematically. As we move from the traditional hierarchical working to self-managing and agility, it is evident for teams to see the radical shift in people's day-to-day behaviors. These new ways of working bring in an increased sense of ownership, proactive, open communication, accepting failures, and more importantly trust and transparency among team members. Agile maturity assessments are tools or processes used to evaluate and measure an organization's or team's level of agility and their effectiveness in implementing Agile principles and practices. These assessments help identify areas of strength and improvement, enabling organizations to enhance their Agile adoption and transformation journey

Effect of Plyometric Exercises Versus Speed Agility Quickness Training on Agility, Speed, Power, Dynamic Balance and Reaction Time in Amateur Badminton Players

Background: Badminton being one of the most popular and fastest racket sport, demands the players to have different skills and fitness level in-order to excel. Skills like power, agility, speed, dynamic balance and reaction time are few of them Aim: This study aims to compare the effect of plyometric exercises versus speed agility quickness (SAQ) training on agility, speed, power, dynamic balance and reaction time in badminton players.Methods: An experimental study was conducted in 36 amateur badminton player who were divided in 3 groups with 12 participants in each – Plyometric training group, SAQ training group and control group. All received intervention for 6 weeks. The outcome measures used were a) agility- Illinois agility test, b) speed- 30 meters’ sprint test, c) power- vertical jump test, d) dynamic balance- modified star excursion balance test and e) Reaction time- simple visual reaction time task.Statistical analysis: Statistical analysis was performed using SPSS software, version 24. Paired t test was used to compare pre-post differences in each group. Intergroup comparison was evaluated using ANOVA test Results: Plyometric group showed a significant improvement in the agility, speed, power, posterolateral and posteromedial directions in modified star excursion balance test and reaction time using paired t test. Speed Agility Quickness group revealed significant difference in speed, agility, all three directions in modified star excursion balance test. In control group, significant improvement was seen only in anterior and posteromedial directions in modified star excursion balance test. There was significant difference between the groups in agility, power and speed using ANOVA test. Further post hoc analysis revealed that plyometric and SAQ group showed no statistically significant difference when compared with each other except for power which showed more improvement in the plyometric group.Conclusion: Both plyometric and SAQ training were equally effective in improving speed and agility in badminton players. Power was seen to be improved more in plyometric group. Hence, these training protocols can be used as evidence-based approach to improve skills in badminton players for optimal performance.

Effect of proprioceptive neuromuscular facilitation and dynamic stretching on flexibility, agility, and balance in hamstring tightness among collegiate level badminton players

Background: The development of muscular damage is typically attributed to intrinsic factors, such as muscle tension. Additionally, it has been demonstrated that muscular stiffness is the primary cause of the risk of pathological disorders of the knee and spine. Hamstring tightness leads to high risk of recurrent injury, decreases the performance in athletes, lead to post-exercise soreness and decreases coordination among athletes. Objectives of current study were to find out the effects of PNF and dynamic stretching on flexibility, balance, and agility among collegiate level badminton players having hamstring tightness. Methods: 110 participants were screened and 68 participants were recruited according to the selection criteria and were randomly allocated to Group A (PNF stretching) (N=34) and Group B (Dynamic Stretching) (N=34). The exercise program underwent training for 30 min, 3 times per week for 4 weeks. Results: Group A and Group B demonstrated significant improvement in Flexibility, Balance, and Agility (p<0.0001). Whereas, no significant difference was seen when intergroup comparison was done (p>0.005). Conclusions: The study concludes that there is significant improvement in the Flexibility, Balance, and Agility after implication of 4 weeks of PNF and Dynamic Stretching in Collegiate Level Badminton players having Hamstring tightness. This evidence substantiates that these exercises do recruit the Hamstring muscles and provides further insight into the role of the Hamstring muscles to keep the body flexible.

Treinamento pliométrico de membros superiores e inferiores em 5 semanas melhora desempenho físico de estudantes de educação física / Pliometric training in 5 weeks improves physical performance of physical education students: a pilot study

: Este estudo investigou o impacto de 5 semanas de treinamento pliométrico em membros superiores e inferiores sobre o desempenho físico em estudantes de Educação Física. Foram recrutados 16 estudantes do sexo masculino de 18 a 23 anos divididos em 2 grupos (Controle e Treino). O grupo Treino foi submetido ao treinamento pliométrico de membros superiores e inferiores por 5 semanas com 3 sessões/semana de 30-40 minutos/sessão, composta de 10 exercícios de braço e perna (10-20 repetições/exercício). Antes e imediatamente após o programa de treinamento pliométrico, os indivíduos foram avaliados por parâmetros antropométricos (peso, estatura, índice de massa corporal e percentual de gordura), nível de flexibilidade e desempenho físico (forças de toque e de ataque, salto vertical, sprint de 20 m e agilidade). Dados de flexibilidade e desempenho físico foram avaliados por análise de covariância (ANCOVA), além da correlação de Pearson entre as variáveis de desempenho físico após 5 semanas de treinamento. O grupo Treino exibiu maior ganho de desempenho no salto vertical quando comparado ao grupo Controle (p< 0,05). Todavia, não foi observada diferença significativa entre os grupos Treino e Controle nos ganhos de força de toque e de ataque, no desempenho do teste de sprint de 20 m, no teste de agilidade e de flexibilidade (p> 0,05). Houve correlação positiva entre os testes de forças de toque e de ataque com o salto vertical (p< 0,001, r= 0,633; e p< 0,001, r= 0,639; respectivamente), como também correlação dos testes salto vertical com os testes de velocidade (p< 0,001, r= -0,768) e agilidade (p< 0,002, r= -0,537) após o treinamento. Conclui-se que 5 semanas de treinamento pliométrico de membros superiores e inferiores exibiram melhora no desempenho do salto vertical de estudantes de Educação Física, bem como observou-se correlação entre os parâmetros neuromusculares anaeróbicos de membros inferiores e superiores após o período de treinamento.(AU)

This study investigated the impact of 5 weeks of plyometric training on upper and lower limbs on physical performance parameters in Physical Education students. Sixteen male college students aged 18 to 23 years were divided into 2 groups (Control and Training). The Training group was submitted to 5 weeks of plyometric training for upper and lower limbs, with 3 sessions per week for 30-40 minutes per session. Training sessions consisted of 10 arm and leg exercises (10-20 repetitions per exercise). Anthropometric parameters (weight, height, body mass index and body fat percentage), level of flexibility and physical performance (touch and attack strength, vertical jump, 20m sprint, agility) were assessed before and immediately after the plyometric training program. Flexibility and physical performance data were assessed by covariance analysis (ANCOVA), in addition to Pearson's correlation among physical performance parameters after 5 weeks of training. The Training group showed a greater gain in the vertical jump performance when compared to the Control group. However, no significant difference was observed between the Training and Control groups for touch and attack strength gains, for 20 m sprint performance gains, and for agility and flexibility test gains. There was a positive correlation between the tests of touch and attack strengths with vertical jump performance. There was also positive correlation between touch and attack strength with vertical jump (p< 0.001, r= 0.633; e p< 0,001, r= 0.639; respectively), and between vertical jump performance and 20m sprint performance (p< 0.001, r= -0,768) and agility test after training (p< 0.002, r= -0,537). It is concluded that 5 weeks of plyometric training for upper and lower limbs showed improvement in the vertical jump performance in Physical Education students. There was also a correlation between the anaerobic neuromuscular parameters of lower and upper limbs after the training period.(AU)

Association of sex-related differences in body composition to change of direction speed in police officers while carrying load / Asociación de diferencias relacionadas con el sexo en la composición corporal para cambiar la velocidad de dirección de oficiales de policía durante el transporte de carga

Regardless of sex or body size, police tasks may require officers to change direction speed (CODS) under occupational loads. The purpose of this study was to investigate body composition and CODS in female and male police cadets in both unloaded and occupationally loaded conditions. Body composition and CODS of 51 female (FPC) and 70 male police cadets (MPC) were assessed. Six body composition indices were used: Body mass index (BMI), percent body fat (PBF), percent of skeletal muscle mass (PSMM), protein fat index (PFI), index of hypokinesia (IH), and skeletal muscle mass index (SMMI). The CODS was assessed by Illinois Agility Test (IAT) and IAT while carrying a 10-kg load (LIAT). An independent sample t-test was used to identify the differences between the sexes. The regression determined associations between body composition and LIAT. The alpha level was set at p < 0.05 a priori. MPC had significantly higher (p < 0.001) BMI, PSMM, PFI and SMMI and lower PBF and IH than FPC. MPC were also faster in IAT and LIAT, carrying lower relative loads that imparted less of an impact on CODS performance. Body composition was strongly associated with the time to complete LIAT (R2 = 0.671, p < 0.001). Difference in relative load and body composition influenced CODS performance in both unloaded and loaded conditions. Thus, optimizing body composition through increasing skeletal muscle mass and reducing fat mass could positively influence unloaded and loaded CODS performance and improve elements of police task performance.

El trabajo policial puede requerir que los oficiales cambien la velocidad de dirección (CVD) bajo cargas ocupacionales, indistintamente del sexo o tamaño corporal. El propósito de este estudio fue investigar la composición corporal y los CVD en cadetes de policía de ambos sexos, tanto en condiciones de descarga como de trabajo. Se evaluaron la composición corporal y los CVD de 51 mujeres (CPF) y 70 cadetes de policía masculinos (CPM). Se utilizaron seis índices de composición corporal: índice de masa corporal (IMC), porcentaje de grasa corporal (PGC), porcentaje de masa muscular esquelética (PMME), índice de grasa proteica (IGP), índice de hipocinesia (IH) e índice de masa muscular esquelética (IMME). El CVD fue evaluado por Illinois Agility Test (IAT) y IAT mientras transportaba una carga de 10 kg (LIAT). Se usó una prueba t de muestra independiente para identificar las diferencias entre los sexos. La regresión determinó asociaciones entre la composición corporal y LIAT. El nivel alfa se estableció en p <0,05 a priori. CPM registraron un IMC, PMME, PGC y IMME significativamente más altos (p <0,001) y PGC e IH más bajos que las mujeres (CPF). Los CPM también fueron más rápidos en IAT y LIAT, llevando cargas más bajas, las que tuvieron un impacto menor en el rendimiento de CVD. La composición corporal estaba asociada con el tiempo para completar LIAT (R2 = 0,671, p <0,001). La diferencia en la carga relativa y la composición corporal influyeron en el rendimiento de CVD tanto en condiciones descargadas como cargadas. Por lo tanto, la optimización de la composición corporal a través del aumento de la masa del músculo esquelético, y la reducción de la masa grasa podrían influir de manera positiva en el rendimiento de CVD descargados y cargados, mejorando el rendimiento del trabajo policial.

The Performance of the Agility System for Interferon Gamma Release Assay Using QuantiFERON TB Gold In-Tube Assay

BACKGROUND: As stated in ‘The Action Strategy for Tuberculosis-Free Korea,’ last March, high-throughput, large-scale analytical instruments for interferon gamma release assays (IGRA) are demanded by many clinical laboratories using the QuantiFERON-TB Gold In-Tube assay (Cellestis/Qiagen, Australia). Agility (Dynex Technologies, USA) is an automated high-throughput enzyme linked immunosorbent assay analyser. The present study aimed to evaluate its accuracy and speed. METHODS: Pooled plasma was prepared using samples obtained after IGRA testing. Analyses of precision, linearity, cut-off evaluation, and comparison with conventional methods were performed for multiple Agility instruments according to the Clinical and Laboratory Standards Institute EP5-A3, EP6-A, EP9-A3 and EP12-A2 guidelines. The turnaround time and throughput were also analysed. RESULTS: The coefficient of variation range was 2.48%–4.0%, 7.01%–11.17%, and 9.69%–14.84% for the repeatability, between-run precision, and between-day precision analyses, respectively. The linearity ranged from 0 to 10.541. Comparison analysis presented a high concordance of Agility with the conventional instrument, DS2 (Dynex Technologies), and manual method for IGRA. The cut-off value of 0.35 IU/mL was well compatible with the C50. It was identified that the C50±20% contained the C5–C95 interval. The average turnaround time was 3.84 hours, from the submission of pre-treated samples to the reporting of results. The throughput was determined to be 290 tests during a routine working time of 8 hours. CONCLUSIONS: Agility showed high precision, linearity, concordance, and had a 2.5 times faster throughput than with the conventional and manual method. It could be useful for large-scale IGRA testing in latent tuberculosis infection screening project. Samples within C50±20% are suspected to show relatively low reporducible results of high inversion between postivie and negative.

Power and agility testing within the NBA pre-draft combine / Teste de potência e agilidade no NBA pre-draft combine

Abstract Considering agility is a prerequisite for basketball performance and several agility tests have been used during the pre-draft assessment of the National Basketball Association (NBA), the aimed of this study was to examine the associations between pre-draft athletes´ performance scores in NBA draft combine testing protocol. The performance of 480 athletes invited to the NBA pre-draft assessment from 2010 to 2017 was considered. Tests in the NBA Draft Combine considered in this study included the Shuttle Run Test, Lane Agility Test, Sprint Test, and Jump Test (standing vertical leap). Zero order correlations were calculated to examine the associations between performance tests by fitting Bayesian linear regression models. Among running testing, both Shuttle Run Test [r=0.45, 95% confidence interval (CI) 0.34 to 0.56) and Sprint Test (r=0.45, 95% CI 0.37 to 0.54) were moderately associated with the Lane Agility Test. The association between the Sprint Test and Shuttle Run Test was moderate at best (r=0.27, 95% CI 0.16 to 0.38). Correlations between Jump Test and running tests were moderate to large, ranging from -0.51 to -0.19 (Lane Agility Test: r=-0.33, 95% CI -0.42 to -0.24; Shuttle Run Test: r=-0.19, 95% CI -0.31 to -0.07; Sprint Test: r=-0.51, 95% CI -0.59 to -0.43). As a conclusion, we found a moderate to large correlations between the tests performance of the NBA Draft Combine, implying that the overall procedures may provide in part overlapping information about basketball maximal short term performance.

Resumo O objetivo deste estudo foi examinar as associações entre os escores de desempenho dos atletas no Pre-Draft Combine da NBA. Foram examinados os desempenhos de 480 atletas nas avaliações do Pre-draft Combine da NBA de 2010 a 2017. Os testes do Draft Combine considerados incluíram o Shuttle Run Test, o Lane Agility Test, o Sprint Test e o Jump Test (salto vertical em pé). Correlações de ordem zero foram calculadas para examinar as associações entre os testes de desempenho através da adequação de modelos de regressão linear Bayesiana. Entre os testes de corrida, tanto o teste Shuttle Run (r = 0,45, intervalo de confiança (IC) de 95% 0,34 a 0,56) e teste de Sprint (r = 0,45, IC 95% 0,37 a 0,54) foram moderadamente associados com o Teste Lane Agility. A associação entre o Sprint Test e o Shuttle Run Test foi de moderada para alta (r = 0,27, IC 95% 0,16 a 0,38). As correlações entre o Teste de Salto e os testes de corrida foram de moderada a grande, variando de -0,51 a -0,19 (Lane Agility Test: r = -0,33, IC 95% -0,42 a -0,24; Teste Shuttle Run: r = -0,19, IC 95% -0,31 a -0,07; Teste de Sprint: r = -0,51, IC 95% -0,59 a -0,43). Assim, foi verificado uma correlação de moderada a grande entre o desempenho dos testes do Draft Combine da NBA, o que indica que os procedimentos gerais podem fornecer, parcialmente, informações sobrepostas sobre o desempenho máximo de curto prazo do basquetebol.

Attitude Towards Ageing And Physical Performance Among Adults 55 Years Old And Above

@#Negative attitudes towards ageing are reported to be associated with greater functional impairment in older adults.There is limited information regarding attitudes towards ageing and physical performance in regard to adults aged 55 to 64 years. The objective of our study was to examine the association of attitude towards ageing on physical performance which includes mobility, agility and falls risk. This cross sectional study was conducted at five senior citizen clubs around Klang Valley in Malaysia. A total of 154 community dwelling adults aged 55 and above (mean:65.8+6.82) participated in this study. Attitude towards ageing was measured using Kogan’s Attitude towards Older People Questionnaire (KAOP). Mobility and agility were measured using gait speed test and ten step test respectively. Risk of falls was assessed using physiological profile aproach (PPA). Approximately 75% of the participants had positive attitude towards ageing with high to very high risk of falls. A significant (p<0.05) correlation was demonstrated between attitude towards ageing, falls risk and gait speed.Regression analysis showed that attitudes toward ageing had a relationship with falls risk, explaining 6% of the variance, F (1, 152) =10.26, p<0.01.The results of this study suggest that there is some relationship between attitude towards ageing and falls risk measured using a combination of physical performance test. Positive attitude towards ageing should be promoted among adults in an earlier age for overall physical health among older adults.

Introduction: The associations between Body Mass Index and child agility are not well understood in the literature. Objective: To analyze the association between Body Mass Index levels and agility in children and adolescents. Methods: cross-sectional study with volunteers aged 10 to 14 years. Separated into: normal weight group (PN= 22), overweight/obese group (EP/OB= 22). All of them underwent anthropometric and agility measurements. Stature and body mass were measured to determine Body Mass Index using the suggestion of the World Health Organization. To measure agility, the Shutle Run test was used because it requires poor motor skills and good reliability. In the week preceding the definitive measures, the volunteers were familiar with the procedures and the execution of the tests. For all the statistical calculations it adopted the level of significance of (p≤ 0.05). Results: There was a significantly positive and moderate correlation between Body Mass Index and agility levels in the group as a whole (r= 0.46, p= 0.03). The results of the t-test confirmed the existence of a significant difference between the agility level of the overweight and obesity group and the normal weight group (p< 0.05). Conclusion: There was a significant correlation between Body Mass Index and agility levels in the sample analyzed; and that the group classified by BMI as EP/OB had a level of agility significantly lower than the group classified asnormal weight(AU)

The relationship between physical fitness and shooting accuracy of professional basketball players

The aim of this study was to examine the relationships among physical fitness of professional Bosnian basketball players (n = 38) and shooting accuracy during one basketball season. A related, secondary aim was to examine relationships between basketball shooting assessments and competitive shooting accuracy during game play. Physical fitness components included: muscular endurance and aerobic endurance, lower and upper-body power, speed, agility, anaerobic capacity and anaerobic power. The specific basketball shooting accuracy was assessed by stationary and dynamic shooting assessments. Competitive shooting accuracy was represented by data collected during one basketball season for each player (free throw, field goal, and three-point %). Results of the regression analyses showed that there were significant positive relationships among shooting assessments and competitive shooting accuracy during game play. The relationship was stronger when the dynamic shooting tests were applied compared to the stationary tests. However, few or weak relationships existed among physical fitness components and competitive shooting accuracy. Only the power tests showed to be good predictors for shooting over longer distances. The findings support the inclusion of the dynamic basketball shooting accuracy tests in regular basketball assessment procedures as a valuable testing instrument.

"A relação entre aptidão física e precisão de arremesso dos jogadores profissionais de basquetebol." O objetivo do presente estudo foi identificar a relação entre a condição física de basquetebolistas profissionais bósnios (n=38) na precisão de arremesso no decorrer de uma temporada competitiva. Adicionalmente, pretendeu-se verificar a relação entre a avaliação específica e a precisão de arremessos durante os jogos. As variáveis de condição física foram as seguintes: resistência de força, resistência aeróbia, potência dos membros inferiores e superiores, velocidade, agilidade, capacidade e potência anaeróbia. A avaliação específica do arremesso foi testada através da utilização de arremessos estáticos e dinâmicos. A precisão dos arremessos durante os jogos foi realizada no decorrer da temporada competitiva mediante análise das seguintes variáveis: lance-livre, arremessos de quadra, e percentagem de arremessos de três pontos. As análises de regressão indicaram a existência de uma relação positiva entre as avaliações específicas dos arremessos e a precisão durante os jogos, a qual foi mais forte nas situações de arremessos dinâmicos comparados aos estáticos. Contudo, as relações existentes entre as variáveis de condição física e a precisão de arremesso durante os jogos foram menores e pouco significativas. Apenas os testes de potência mostraram ser bons preditores para os arremessos efetuados a longas distâncias. Os resultados obtidos apoiam a inclusão de testes de avaliação da precisão de arremessosrealizados de forma dinâmica em procedimentos regulares de avaliação no basquetebol, constituindo-se como instrumentos valiosos para ocontrole do rendimento.

Fitness-related factors associated with survival in older women / 体力科学

This study evaluated the relation between physical fitness and survival. This prospective cohort study included 74–88-year-old women who were living at home and who reported no disability in activities of daily living. Subjects completed physical fitness tests assessing walking ability, muscular strength, flexibility, agility, and balance. They were administered a follow-up interview 14 years later. Of 63 older women, 58 died during that 14-year period. Among the 16 physical fitness measurements, significant association with survival time was found for 11 measurements using Cox proportional hazards model (Adjusted for age, BMI, and TMIG index of competence score). Among them, maximum walking time was an indicative main physical fitness factor for predicting the survival of elderly women. The hazard ratio per 1 s of 10m maximum walking time was 1.93 (95% Confidential Interval [CI], 1.54–2.41). Among muscular strength, flexibility, agility, and balance, the most influential physical fitness element to survival was agility (nerve reaction time). Therefore, the functional decline of the nervous system is expected to affect survival strongly. When 10 m maximal walking speed is 8.5 s or more, the median survival time of elderly women is 6.75 years (95%CI, 6.25–7.67), but if the time is less than 8.5 s it is 11.58 years (95%CI, 10.25–13.08, p<0.0001; log-rank test). The ability to move rapidly is identified as the main physical fitness factor associated with survival.
