Anthropometric and Physical Fitness Component Profiles in Malaysian Adolescence Recreational Karateka

Objective: Measuring the physical fitness components of athletes provides crucial information in designing an individual training program to enhance performance. However, a huge gap is identified, in the lack of baseline physical fitness profiles among Malaysian adolescence Karateka. Our objective is to describe the physiological profiles of Malaysian adolescence Karateka.Material and Methods: This cross-sectional study was conducted in the Klang Valley; at eight Karate training facilities in participants aged 13-19 years old. Demographic data, anthropometric and short physical performance batteries, 3-minute YMCA step test, Jamar handgrip dynamometer test 3-minutes and 1-minute sit-up test were collected and analysed using statistical package for social sciences version 26. Results: The mean age was 15.8±1.8 years. The mean body mass index was 21.5±4.5 kg.m2, the mean VO2 peak was 59.0±12.4 ml.kg.min, and the mean hand grip strength was 30.7±9.3 kg. Karateka in higher age groups (18-19 years) had a significantly higher weight (median=64.4, p-value=0.003), higher skeletal muscle mass (median=27.6, p-value=0.006), higher hand grip strength (median=37, p-value=0.000), and higher 1 min sit up test (median=32, p-value=0.071). Male Karateka had a higher skeletal muscle mass (median=25.9 kg, p-value=0.000), higher hand grip strength (median 33.1 kg, p-value=0.000), higher 1 minute sit-up test (median=32, p-value=0.001) and higher VO2 peak (median 67.2 ml.kg.min, p-value=0.000). Conclusion: This serves as baseline anthropometric and physical fitness profiles among Malaysian adolescence Karateka.

Prevalence and Outcomes of Orthostatic Hypotension in Hemorrhagic Stroke Patients During Hospitalization.

Orthostatic hypotension (OH) is highly prevalent in hospitalized patients and can lead to major consequences. The prevalence of OH among patients with stroke has also been reported to be high in in-patient cohorts. However, no previous analysis has focused exclusively on patients with hemorrhagic stroke, a group that may have a different disease profile, including a greater need for blood pressure control and surgical intervention. This study aims to examine the prevalence of OH, its risk factors, and potential impact in patients who were hospitalized due to hemorrhagic stroke. A retrospective analysis of in-patient records between 1 January 2021 and 30 April 2023 was conducted for patients with stroke due to intracerebral hemorrhage (ICH) or subarachnoid hemorrhage (SAH) who were referred to rehabilitation at a tertiary hospital in Singapore. OH was defined as a drop in systolic blood pressure of ≥20 mmHg or diastolic blood pressure of ≥10 mmHg during the sit-up test as part of the rehabilitation assessment. Additional data collected included demographic information, length of stay, antihypertensive medications used at the time of assessment, comorbidities, and discharge functional outcomes as measured by a modified Rankin Scale. A total of 77 patients (65 [84.4%] with ICH and 12 [15.6%] with SAH) were included in the analysis. The prevalence of OH was 37.7%. A history of surgical intervention was identified as the major risk factor for the development of OH (odds ratio 4.28, 95% confidence interval 1.37 to 13.35, p = 0.009). There was no difference in hospital length of stay or discharge modified Rankin Scale scores between the two groups. OH was frequently observed among patients with hemorrhagic stroke during the acute/subacute stage and should be monitored, especially in patients who require surgical intervention.

The Effect of Traditional and Suspension Strength Training on Motor Skill Development in Regular Exercisers

The aim of this study was to investigate the effects of conventional and suspension strength training on selected motoric skills in individuals who exercise regularly. A total of 30 men with a mean age of 36.53 years participated in the study voluntarily. The participants were divided into two groups as traditional strength group (TSG, n=15) and suspension strength group (SSG, n=15). Height, body weight, body mass, push-up, sit-up, plank, CMJ, y-balance and 1TM strength tests were performed before and after two different 8-week strength training programmes. The data were analysed using SPSS 26 package programme. After the normality assumption test, since the data showed normal distribution, Paired Samples T Test was used in the comparison of two dependent groups. As a result of the analyses, a statistically significant difference was found in BMI, push-ups, sit-ups, CMJ, bench press and squat 1TM values (p>0.05). A statistically significant difference was found in BMI, push-ups, sit-ups, plank, balance right and left foot, bench press and squat 1RM values (p>0,05). In the posttest comparison between the groups, a significant difference was observed only in the plank test (p>0.05). As a result of the study, it was determined that strength exercises (push-ups, squats, and sit-ups) applied on non-fixed surfaces showed more improvement than traditional strength training, although not statistically significant. In plank performance, there was an improvement in favour of the SKG group.

The effectiveness of the physical education curriculum following the Sports Club model on the physical development of high school students in Vietnam

Background and Study Aim. The physical development of high school students is often hindered by the limitations of traditional physical education programs, which may not fully engage students or promote balanced physical growth. In light of these concerns, the need to explore alternative educational models that can enhance students' physical development has become evident. The purpose of this article is to evaluate the potential effectiveness of a physical education curriculum following the Sports Club model in improving the physical development of high school students. Material and Methods. A total of 84 female 10th-grade students participated in the study. They were divided into two groups: an experimental group of 42 students following the Sports Club model and a control group of 42 students following the current physical education curriculum. The experiment lasted for 17 weeks. Both groups completed initial and final physical fitness tests. These tests included the 30-second sit-up test (to assess core strength), the 30-meter sprint test (to measure speed), the 4 × 10-meter shuttle run test (to evaluate agility), the standing long jump test (to measure explosive leg power), and the 5-minute running field test (to assess endurance). Results. The female students in the experimental group demonstrated greater physical development compared to the control group in all five assessment tests. The experimental group showed the most significant improvement in the 30-second sit-up test, with a growth rate of 26.71%. The lowest growth was observed in the 5-minute running field test, at 9.92%. In contrast, the control group showed its highest improvement in the 30-second sit-up test, with a growth rate of 9.44%. However, there was minimal to no improvement in the 4 × 10-meter shuttle run and the 5-minute running field test for the control group. Conclusions. The Sports Club model improved students' physical fitness more effectively compared to the current curriculum, offering greater benefits in all tested areas. It is recommended that teachers further integrate and refine the implementation of the Sports Club model in future physical education programs to enhance teaching effectiveness.

EFFECT OF MUSIC ON PHYSICAL FITNESS FOR GRADE 11 IN FEMALE VOVINAM STUDENTS AT TRAN QUANG KHAI HIGH SCHOOL, HOCHIMINH CITY, VIETNAM

The purpose of this study was to evaluate the application of music to female students when participating in Vovinam sessions at Tran Quang Khai High School, Hochiminh City, Vietnam, to improve their physical fitness. 80 healthy female students were chosen and divided into two groups: 40 female students were in the experimental group with the application of music, and the 40 female students remaining were in the 36 training sessions without music. The music tempos were around 120-140 bpm. Two famous Vietnamese songs were chosen to use in Vovinam for training. Six fitness tests, such as 30 seconds sit-up test (evaluated the core strength), 30m sprint test (speed), 4x10m Shuttle run test (agility), standing long jump test (the explosive power of the legs), handgrip strength test (strength of the hand), 5 minutes running field test (maximal aerobic speed-MAS) were used to evaluate the physical fitness for female students. The results indicated that the application of music improved the power of the legs, agility, speed, core strength, strength of the hand, and MAS. In short, the application of music for female students participating in badminton had many benefits in increasing their physical fitness. More studies should evaluate the influence of music on many kinds of sports and assess the concentration of participants when applying music.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0715/a.php" alt="Hit counter" /></p>

Effects of 8-weeks Surf Skateboard training on physical fitness in young people

BackgroundSurf skateboards have grown in popularity among young people in recent years. However, no research studies have analyzed the effect of surf skateboarding on physical fitness. ObjectiveThe purpose of this study was to determine the effects of 8-week surf skateboard training on physical fitness in young adults. MethodsTwenty-two young people, ages 18–24 years were randomly assigned into two groups: a control (CON; n ​= ​11) and surf skateboarding (SSK; n ​= ​11) group. The surf skateboard training group received an eight-week intervention consisting of three 60-minute (min) sessions per week, while the control group continued with their normal daily lives. Physical fitness was assessed before and after the intervention through a battery of tests that included body composition, cardiorespiratory fitness, muscular strength and endurance, flexibility, and balance. ResultsThe results showed that the SSK group demonstrated significant (p ​< ​0.05) improvements in maximum voluntary ventilation, back and leg strength, lower body muscular endurance by the sit-to-stand tests, and balance in all direction compared with the pre-test and the CON group. In addition, the SSK group showed significantly (p ​< ​0.05) decreased body weight, body mass index, percent body fat, and resting heart rate, while increased maximum oxygen consumption, pulmonary function, respiratory muscle strength, upper body muscular endurance by the sit-up test and flexibility compared with the pre-test. ConclusionThe findings suggest that surf skateboard training have an effective physical activity intervention to improve body composition, cardiorespiratory fitness, muscular strength and endurance, flexibility, and balance in young people.

Assessment of Motor Performance and Self-Perceived Psychophysical Well-Being in Relation to Body Mass Index in Italian Adolescents.

The relationship between psychophysical self-perception (PSP), body mass index (BMI) and motor performance (MP) levels, in quantitative and qualitative terms, can be a very interesting connection to investigate. This study aimed to assess MP and PSP according to gender and weight differences (normal weight-Nw/overweight-obese-Ov-Ob) and their relationship to BMI in Italian adolescents. In total, 144 students (F = 72; M = 72) aged between 11 and 13 y.o. participated in this study. They were divided into two groups by gender and into two subgroups based on weight (Nw/Ov-Ob). Standing long jump, sit-and-reach, 10 × 5 m shuttle and sit-up tests to assess MP were carried out, and an ad hoc questionnaire to evaluate PSP was administrated. In comparing the Nw and Ov-Ob subgroups on the basis of BMI for each gender, statistically significant differences emerged in all motor skill tests administered. Regarding PSP, the Nw subgroup showed high and positive levels, while Ov-Ob showed low and negative levels, highlighting a relationship between high BMI and poor motor performance as well as negative psychophysical perception in the Ov-Ob subgroup. this study supports the importance of physical sport activity to regulate excess weight but also contribute to better psychophysical well-being.

Physical fitness components are bone mineral density predictors in adulthood: cross-sectional study

BackgroundHealth-related physical fitness (HRPF) attributes are considered important markers beneficial to various health outcomes. However, the literature is divergent regarding HRPF and bone health in adulthood, especially due to the end of the second and beginning of the third decades of life when the peak bone mass period occurs.ObjectiveTo analyze which HRPF variables are areal bone mineral density (aBMD) predictors in adult males and females.MethodsThis study evaluated 137 healthy young adults aged 18–25 years (50% males). Dual-energy X-ray absorptiometry (DXA) was used to estimate fat mass and lean mass and aBMD, hand grip strength test, sit-ups test, flexibility test, lower limb muscle strength and 20-meter run were used to evaluate physical fitness. Multiple linear regression using the backward method was used to analyze bone mineral density predictors by sex.ResultsHRPF indicators showed correlations from R = 0.28 in the right femoral neck aBMD to R = 0.61 in the upper limbs aBMD in males; in females, correlations from R = 0.27 in total body aBMD to R = 0.68 in the lower limbs aBMD were found. In males, body mass and HRPF indicators were aBMD predictors with HRPF indicators explaining variance from R²=0.214 in the lumbar spine to R²=0.497 in the upper limbs, and in females, with the exception of the lumbar spine, variance from R²=0.237 in the right femoral neck aBMD to R²=0.442 in the lower limbs aBMD was found.ConclusionHealth-related physical fitness components were able to predict aBMD in different anatomical regions in young adults, especially muscle strength and cardiorespiratory fitness indicators for males, while only lean mass and fat mass for females.

Effects of exercise on autonomic cardiovascular control in individuals with chronic, motor-complete spinal cord injury: an exploratory randomised clinical trial.

Secondary analysis of a clinical trial. To assess the impact of 6 months of armcycle ergometry training (ACET), or body weight-supported treadmill training (BWSTT), on autonomic cardiovascular responses to a laboratory sit-up test (SUT) in individuals with chronic (≥1-year post-injury) spinal cord injury (SCI). Tertiary Rehabilitation Centre, Vancouver, Canada. Sixteen individuals with motor-complete (American Spinal Injury Association Impairment Scale A-B) SCI between the fourth cervical and sixth thoracic spinal cord segments, aged 39 ± 11 years, were assessed. Participants were randomized to receive 72 sessions of moderate-to-vigorous intensity ACET (n = 8) or passive BWSTT (n = 8). Changes in mean arterial pressure (finger plethysmography), hemodynamics (Modelflow® method), and heart rate/heart rate variability (HR/HRV; electrocardiography) were measured in response toa SUT before and after 6 months of exercise training. Spontaneous cardiovagal baroreflex sensitivity (cvBRS) was assessed using the sequence method. Neither ACET nor BWSTT impacted hemodynamic responses to SUT or the incidence of orthostatic hypotension (all P > 0.36). ACET increased HR (P < 0.01, ηp2 = 0.34) and high frequency (HF) power HRV responses (P < 0.01, ηp2 = 0.42) to SUT following 6 months of training while BWSTT did not. Consistent with this, cvBRS improved (P < 0.05, ηp2 = 0.16) only following ACET. Improvements in cvBRS were correlated with both the HR (r = 0.726, P < 0.0001) and HF power (r = -0.484, P < 0.01) responses to SUT. Six months of ACET, but not BWSTT, improved cardiovagal baroreflex control of HR but had no effect on BP responses to SUT in individuals with chronic, motor-complete SCI.

Comparison of Core Endurance, Strength, Power, Balance and Flexibility in Young Elite Sailors

Aim: This study examines and compares the core endurance levels, balance performance, muscle strength, and flexibility among young elite saiflors in different sailing classes. Method: Athletes were randomly selected from the Galatasaray Sailing Club and divided into three groups: windsurfing (n=14), optimist (n=13), and laser class (n=13). Demographic features, body mass index, and dominant side of the body were recorded. Upper extremity strength was assessed using a hand dynamometer, while lower extremity power was evaluated through vertical jump, standing long jump, and single-leg jump tests. Core endurance was evaluated with sit-up, plank, and rotary stability tests. Balance and flexibility were assessed using Y balance, straight leg raise, shoulder flexibility, sit and reach, shoulder elevation, and total body rotation tests. The data from the three groups were analyzed using the Kruskal-Wallis H test, and inter-group comparisons were performed with the Mann-Whitney U test. Results: Significant differences were observed among the groups in the hand grip test for both right and left hands (p&amp;lt;0.001). The laser group displayed the highest mean value. The standing long jump test also showed a significant difference between the groups (p&amp;lt;0.05), with the laser group exhibiting the highest mean value. The single-leg jump test revealed a significant difference among the groups (p&amp;lt;0.05), with the windsurfing group having the highest average. The Y balance test indicated a significant difference among the groups (p&amp;lt;0.05), with the optimist group displaying the highest average values. Conclusion: These findings demonstrate that each sailing class necessitates distinct physical attributes and specific performance parameters, particularly in terms of strength and balance.

The effect of an 8-week fitness regime on low back pain and core strength in high-risk professionals.

Low back pain is prevalent among various populations and greatly impacts their quality of life. Professions that incorporate several working hours combined with heavy labor are the most affected. The aim of this study was to examine the effects of an 8-week core training intervention in emergency personnel. Sixteen randomly selected male participants; police officers (N.=8) and firefighters (N.=8) (mean age: 40.75 years; mean height: 177.69 cm; mean body mass: 85.50 kg) performed various testing procedures that assessed core muscle strength and endurance and filled the Oswestry Disability Index Questionnaire regarding the level of low back pain before and after the intervention. The 8-week intervention consisted of two 45-60-minute sessions per week that included ten core-related exercises. Statistical analysis; paired samples t-test and Wilcoxon Signed-Rank Test, demonstrated significant effects in the 30-sec sit-up test, the Double Leg Lowering Test and the isometric abdominal strength measurements; P value level of significance was set at P≤0.05. All participants had minimal lower back disability before and after the intervention. The results demonstrated that the prescribed regime could improve core strength and endurance in high-risk professionals. The most important finding is that training interventions for emergency personnel are most effective when they incorporate a variety of exercises that target the core musculature in all planes of movement and engage the whole range of motion.

Exploring the effect of the clothes used in physical education class on some physical fitness parameters

Clothing used in physical education class can affect physical fitness. Therefore, the aim of this study was to explore the effect of clothes used in physical education class on some physical fitness parameters (anthropometric characteristics, muscular endurance, flexibility, explosive strength). 34 secondary school student were recruited for this study. After the baseline assessments, the students were randomly divided into two groups: one group wearing shorts and T-shirts and the other wearing school uniforms. The analysis revealed baseline differences in the sit-and-reach, standing long jump, sit-up and 20 m sprint tests in within-group comparisons. Girls performed better when wearing shorts and T-shirt in the 20 m sprint test (Z(-3.622)=4.45, p&lt;0.01), sit-and-reach test (Z(-3.668)=27.41, p=0.01), SLJ (Z(-3.635)=124.02, p=0.01) and sit-up test (Z(-3.534)=18.82, p&lt;0.01). Similarly, boys performed better when wearing shorts and T-shirt in the 20 m sprint test (Z(-3.574)=4.68, p&lt;0.01), sit-and-reach test (Z(-3.657)=24.64, p=0.01), SLJ (Z(-3.667)=141.14, p=0.01) and sit-up test (Z(-3.537)=22.91, p&lt;0.01). In conclusion, the results revealed that wearing shorts and T-shirts in physical education class had a positive effect on some physical fitness parameters. This underlines the advantages of wearing appropriate clothing in physical education class to promote physical fitness.

Changes in Physical Fitness in Youth Padel Players during One Season: A Cohort Study.

The aim of this study was to investigate how physical fitness performance, which is related to the strength and power of the lower extremities and core, as well as lateral agility, changes across 20 weeks of in-season training in youth female and male padel players. This study was conducted using a prospective cohort design on 16 Swedish high school padel players aged between 15 and 18 years old. The players were assessed at baseline with five tests of their physical fitness and followed prospectively, with the registration of their training load for 20 weeks, and then assessed at a follow-up, approximately five months later. The players increased their performance in all tests (p ≤ 0.02). The mean improvement in their Isometric squat test performance was 20% for peak force, 18% for relative strength value and 69% for average rate of force development. Their improvement in the squat jump test performance was 9%, whereas the improvement in their countermovement jump test was 6%. For the 30 second sit-up test, an improvement of 14% was observed. Improvements were also noted for the 30 second side hop test performance on both the right (9%) and left leg (11%). The effect size ranged from 0.31 to 1, respectively, for the tests, representing a small to large effect. The data from this study suggest that an improvement in physical fitness performance can be obtained during 20 weeks of padel training.

Associations of Cardiorespiratory Fitness and Muscular Endurance Fitness With Pulmonary Function in Physically Active Young Adults

RationaleWhile the beneficial effects of physical fitness on general health are well-documented, the specific relationship between different types of physical fitness, particularly cardiorespiratory fitness (CRF) and muscular endurance fitness (MEF), and lung function in physically active young adults remains less explored. ObjectiveThis study investigated the relationship between CRF and MEF, and their correlation with lung function in physically active young adults. MethodsThis cross-sectional study involved a cohort of 1227 physically active young adults without lung diseases. Lung function was assessed using FEV1, FVC, and FEV1/FVC measurements. The 3000-m run was used to assess CRF, and the 2-min push-up and sit-up tests were used to assess MEF. Multivariable linear regression analysis was used to evaluate the relationships between these fitness measures and lung function, adjusting for potential covariates. ResultsEnhanced CRF was associated with superior FEV1 and FVC after adjusting for covariates (β=−.078, p=.015 for FEV1; β=−.086, p=.009 for FVC). Push-ups were positively associated with FEV1 (β=.102, p=.014), but not with FVC. In contrast, sit-ups showed no significant correlation with lung function in the fully adjusted model. ConclusionThe study demonstrated a clear association between improved physical fitness and better lung function in physically active young adults, with various exercises showing distinct associations with lung metrics. Notably, push-ups were particularly associated with higher FEV1. A future prospective study is necessary to determine whether routine exercises, such as push-ups, might lead to greater lung function.

ISOLATED AND COMBINED IMPACTS OF WEIGHT TRAINING AND LADDER TRAINING ON SELECTED PHYSICAL, PHYSIOLOGICAL AND SKILL PERFORMANCE VARIABLES AMONG WOMEN KABADDI PLAYERS

Background and study aim: To optimize performance in kabaddi, players require a blend of strength, agility, endurance, and speed. While weight training is increasingly popular due to its ability to enhance cardiovascular fitness and functional strength, there is limited understanding of its specific effects on the physical and physiological attributes of kabaddi players. Moreover, skill performance is integral to improving playing abilities. It is important to examine the isolated and combined impact of ladder training and weight training on select physical, physiological, and skill-related performance variables in female kabaddi players. Material and methods: sixty female kabaddi players were randomly assigned to three experimental groups. Experimental group I weight training group (WTG) (N = 15) (Age21.08±0.9, Height: 168.25±3.86, Weight: 65.16±2.32) Experimental group II Ladder training group (N=15) (LTG) (Age: 21.15±1.20, Height: 159.28±2.59, Weight: 60.12±2.42) Experimental group III Combined Training Group (CTG) N = 15) (Age: 21.11±0.52, Height: 168.251±3.86, Weight: 65.16±2.32) and Combined Group (CG) (N = 15) (Age: 21.08±0.9, Height: 160.10±2.11, Weight: 59.17±2.02)their age ranged between 18 and 25. Subjects were randomly selected from the Dr.Sivanthi Aditanar College of Engineering, Tiruchendur, Govindammal Aditanar College for Women, Tiruchendur, Wavoo Wajeeha Women's College of Arts and Science, Kayalpatnam, Thoothukudi, India. Testing Variables: The study assessed various physical, physiological and skill performance variables to evaluate in the impact of combined weight and ladder training. Agility was measured using the Illinois Agility Test, while Leg Explosive Power was assessed through the Standing Broad Jump. Muscular Strength Endurance was determined via the Sit ups test and physiological variables namely VO2 Max was measured by Cooper 12 Minutes run and walk and Breath Holding Time was measured by Nostril Clip Method. Additionally, skill performance variable namely toe touch ability was assessed by Toe Touch Test and considered a dependent variable for overall assessment.Statistical Analysis: statistical analysis using dependent ‘t’ test and Analysis of covariance (ANCOVA) to find out the significance among the mean differences, whenever the ‘F’ ratio for adjusted test was found to be significant, Scheffe’s post-hoc test was used. In all cases level of significance 0.05.Results: Participants who followed the combined weight and ladder training program showed substantial improvements in their physical, physiological, and skill performance indicators when compared to the control group (p &lt; 0.05). Female kabaddi players overall physical, physiological, and skill performance variables were significantly improved by combined weight and ladder training.Conclusion: The combination of weight training and ladder training significantly enhanced the physical, physiological, and skill-related performance of female kabaddi players. This integrated approach proved more effective than either training method alone, demonstrating that a comprehensive training regimen can maximize overall athletic performance and help players achieve their full potential.

Exercise During Work Hours Improves Fitness: An Evidence-Based Case Report

Relatively tight working hours are problems for employees in urban areas, affecting less time for physical activities. About 59% of office workers in Jakarta are classified as sedentary. The high number of sedentary workers can cause productivity problems due to low fitness. Appropriate interventions are needed to overcome it. We have done literature searches from 7 journal databases in the last 20 years, including ScienceDirect, EBSCOhost, PubMed, ProQuest, Scopus, ClinicalKey, and Cochrane. Inclusion criteria include research design in the form of systematic review/meta-analysis/randomized controlled trials, outcomes in the form of physical fitness or work performance, and interventions in the form of workplace exercise or stretching. Three selected articles showed a significant relationship (p-value &amp;lt;0.05) between programmed physical exercise at work and several fitness factors, such as decreased body fat and fat mass, increased lean mass, and increased sit-up and push-up fitness test results. Physical activity at work decreased cardiovascular risk as assessed by VO2max. In conclusion, physical activity during working hours effectively improves health-related fitness. The minimal intervention types needed are aerobics, strength training, and muscle endurance. We recommend providing interventions for workplace fitness and education programs (WFEP).

The effects of kettlebell training versus resistance training using the own body mass on physical fitness and physiological adaptations in obese adults: a randomized controlled trial

Aim of studyThis study aimed to explore the effects of different types of resistance training using kettlebells versus the own body mass, in comparison to a passive control, on key physical fitness and physiological parameters in young, obese adults.MethodsData from 60 sedentary, obese male college students, aged 17–26, were used for final analyses. Participants were randomly assigned to one of three groups: a control group (CG, n = 20, no training), a kettlebell resistance training group (KRTG, n = 20), or a bodyweight resistance training group (BWRTG, n = 20). Selected measures of physical fitness were tested using the 12-minutes run test, the push-up test, the sit-up test, and the sit-and-reach test. Physiological measures included vital capacity, resting and maximum heart rate (HRmax), mean arterial blood pressure, breath holding time, and respiratory rate. Biochemical variables were measured in the morning, in a fasted state, and comprised high and low density lipoprotein, total cholesterol, and triglycerides. The 12-weeks progressive KRTG and BWRTG were specifically tailored using sets, repetitions, and intensity levels.ResultsNotable findings include significant body fat reductions in BWRTG (p < 0.001; d = 1.53) and KRTG (p < 0.001; d = 1.43), and a substantial increase in VO2max for BWRTG (p < 0.001; d = 1.32) and KRTG (p < 0.001; d = 1.34) compared to CG. KRTG also showed significant improvements in vital capacity (p < 0.001; d = 1.61) and reductions in resting heart rate (p = 0.024, d = 1.05) and respiratory rate (p = 0.001, d = 1.55), with BWRTG showing similar trends (resting heart rate: p = 0.041, d = 1.35; respiratory rate: p = 0.001, d = 1.98). Both intervention groups significantly improved breath holding time (KRTG: p = 0.001, d = 1.58; BWRTG: p < 0.001, d = 1.98) and reduced total cholesterol and low-density lipoprotein levels compared to CG.ConclusionsThis study demonstrates that both KRTG and BWRTG are effective in improving body composition and selected fitness and physiological measures. Thus, resistance training using kettlebells or bodyweight training are recommended if the goal is to improve body composition and fitness in obese male adults.Trial RegistrationOSF, September, 28th 2023. https://doi.org/10.17605/OSF.IO/Z6Y9Gosf.io/2mb98

The correlation results show a significant relationship between variables X1, X2, and Y with a correlation coefficient 0.788. Meanwhile, the contribution coefficient of determination is 0.621, or in other words, 62.1% can contribute to variables X1, durability. From the research results, the greater the arm and abdominal muscle strength a person has, the better their ability to smash in badminton.

PHYSICAL FITNESS AND BALANCE PERFORMANCE IN TABLE TENNIS PLAYERS WITH INTELLECTUAL DISABILITIES: A COMPARISON BETWEEN THE YEARS 2016 AND 2022

Training routine is beneficial for people with intellectual disabilities, increasing their physical fitness, improving the balance and consequently reducing the risk of falls. However, during the COVID-19 breakdown, training restrictions could impair these benefits. This is a two-fold study aimed to compare the physical fitness performance and balance in table tennis athletes with intellectual disability (ID) during 2016 and 2022; and to analyse the association between the fitness and balance parameters. Table tennis athletes with ID, from both sexes and members of the Special Olympics Czech Republic, were assessed in 2016 (n=33) or 2022 (n=32). The FUNfitness protocol was used to measure the physical fitness parameters and balance (e.g., functional shoulder rotation, timed sit-to-stand test, partial sit-up test, handgrip test, single leg stance eyes open, single leg stance eyes closed). Comparison and correlation statistical tests were used (p&lt;0.05). The physical fitness parameters and balance presented no statistically significant between the years (2016 vs 2022) or better results in 2022 (single leg stance, partial sit-up test). The correlation of physical fitness parameters and balance demonstrated that balance is positively related to flexibility (single leg stance eyes closed: r=0.32 and 0.58 for males and females, respectively) and lower limb strength (single leg stance eyes open: r=-0.31 and -0.52 for males and females, respectively). In conclusion, the development of flexibility and low limb strength in ID population can help improve the balance, and consequently minimize the risk of falls.

Effects of different types of warm-ups on performance by young volleyball players

The study aimed to compare the impact of warm-up with dynamic stretching (DS), warm-up with foam roller (FR), and warm-up with a combination of FR and DS (CO) on the performance of movement indicators in tests conducted on young volleyball players (n = 8, age = 15.4 ± 0.5 years, height = 176.3 ± 8.6 cm, weight = 64.5 ± 10.9 kg) during the competition year 2021/2022. To assess the effects of warm-up methods (DS, FR, CO), performance in various movement tests was compared. The tests included the sit and reach test (SR), a 1 kg ball throw in a kneeling position (H1), squat jump (SJ), countermovement jump (CMJ), sit-up test (SU), E-Test (ET), and run to cones (RC). The One-way ANOVA analysis did not reveal significant differences in the effects of DS, FR, and CO warm-ups (p &gt; .05) across all investigated indicators. The effect size coefficient (η2) indicated negligible differences (η2 &lt; 0.01), except for the ET indicator, where a small effect size (η2 = 0.028, 95%CI: 0.04-0.31) favoured DS. These findings carry social importance as they contribute to enhancing the efficacy of warm-up routines, both in sports performance and health considerations.
