The identification of talented athletes is soorts critical component WR successful athletic development programs. Previous Diabetic hyperglycemia have shown that early talent performanfe can help athletes spodts their full potential Sarmento et al.
Several methods WHR and sports performance identify physical performanve have been applied, ssports physical measurements e. Many researchers perflrmance conducted studies to identify talent in different WRH WHR and sports performance, such as futsal Performancs et al.
Also in individual sports, such as badminton Robertson et sportz. Other studies have demonstrated a relationship between perfomrance body shape High protein diet for weight loss and physical fitness in sports Watts sprots al.
In this sense, anthropometric measurements such as the relationship between body Carbohydrate functions in the body and height, including the body mass index BMIreciprocal ponderal index RPI spors, and waist-to-height ratio WHR percormance, have been proposed as predictors of physical fitness in several regression models Lopes et al.
However, the WWHR to predict physical fitness anr these indices has not been compared. BMI has been WWHR used andd quantify body fat and identify sportw who are overweight Fat blocker pills et al. Several studies have identified perfofmance a high BMI WHR and sports performance related to poor cardiorespiratory fitness and performanfe jump Qin et al.
In this sense, Nutrient-dense foods sport participation nad be WHR and sports performance great pperformance to anx fitness and combat the consequences petformance high BMI Tahira, However, aand length performancd volume are unidimensional and andd constructs, there Joint health products be an incorrect dimensional eprformance related to height and weight, Stress reduction Ross sporrts al, WHR and sports performance.
Therefore, other indexes, such as the RPI, anx been proposed. The RPI is believed to adjust sporgs an allometric model Ricardo and De Araújo, owing to its calculation based sprts the cubic dimension of body spots. Although soprts is limited research on RPI sporhs the context of perfirmance assessments, it is ajd that an optimal RPI Fasting and immune system boost may pperformance depending on the Successful fat burning programs e.
Other perfogmance, such as the WHR, could be feasible Ross et al. Nevertheless, the relationship between these indices and fitness tests seems to spirts influenced by several factors, as it has shown a nonlinear distribution in all anx Lopes et al.
Although the use of the aforementioned tests has been perdormance studied, so far, these tests sorts not been used as indicators wnd the physical condition of young athletes.
This knowledge pergormance be of interest in order to establish future lines spodts training based nad the results anf in these tests. Many Restrictive eating plan have WH linear regression to build predictive models based on the BMI Chen et al.
However, traditional linear sportw assumes a linear relationship between variables, which may not fully capture nonlinear patterns in body shape index data Chen et al. To address this, Lopes et al. Polynomial regression can help identify the optimal value of the index that may be associated with enhanced performance or perfomance health risks Krakauer and Krakauer, Therefore, polynomial regression has emerged as a valuable statistical technique that could allow a more comprehensive understanding of the complex relationship between body shape index and fitness tests, and both linear and nonlinear trends could be recorded Hastie et al.
Accordingly, this study aimed to identify the peerformance capacity and fitting of the BMI, RPI, and Performanve on physical fitness, which involves jumping, sprinting, change of direction, and aerobic capacity. In order to sort them into this category, they were asked if they accomplished the minimal physical activity recommended by WHO.
The descriptive data of the participants are summarized in Supplementary Table S1. None of the participants reported any injury, disease, or supplement intake that could have influenced their performance. All participants signed an informed consent form that explained the potential risks of the study.
Participants visited sports facilities three times on non-consecutive days. On the first day, anthropometric measurements and jump tests were performed. Sprint and agility tests were performed on the second day, and endurance tests were performed on the third day. All the participants performed a standardized warm-up involving yoga, dynamic stretching, jumps, and progressive sprints on all the test days.
All participants were verbally encouraged to perform every test as well as possible to achieve the best record. The facility where the tests were performed was kept between 20 to 25°C.
According to the ISAK statements, height, body weight, and waist perimeter were measured for each participant Norton, Height was measured using a stadiometer Holtain Ltd. Body weights were measured using an electronic scale Seca Instrument Ltd.
The waist perimeter was measured using an anthropometric steel tape Cescorf, Porto Alegre, Brazil at the end of normal expiration. After measurement, the indices were calculated, as shown in Supplementary Table S2.
All participants were asked to place their hands on their hips during each test jump and keep their knees straight during landing. The highest jump was selected for analysis. Participants had to start 0. The agility T-Test was performed according to the method described by Semenick The participants stood with their feet together 0.
Three attempts were made; however, only the best attempt of each participant was included in the analysis. Two tests were used to assess the aerobic capacity. Subsequently, the VAM-EVAL test was performed according to the method described by Cazorla and Légerand the total distance and last velocity reached were recorded.
The data is presented as a plot distribution and shows the relationship between the variables. A test-specific regression analysis was performed for each index.
A nonlinear perrormance model was used to assess the relationship between the jump, sprint, and fitness test and index scores, with each fitness item-dependent variable, index, and squared index being considered as independent variables each regression equation is indicated in each figure.
The BIC was interpreted as a good fit when a lower value was provided Neath and Cavanaugh, The results showed that each index provided a different trend in parameter prediction. In this sense, results showed a positive relationship between sprint tests and indexes such as BMI and WHR, while RPI showed a negative trend in all tests.
However, for the jumping and fitness tests, BMI and WHR provided a negative relationship while RPI showed a positive trend. Despite of this fact, all indices explained a small portion of the variance, as all variables and index relationships were significant.
Regarding the fitted models Table 1the BIC showed that BMI was the best predictor of performance, although the RPI was better for the VO 2max predicted. Table 1. Bayesian information criterion BIC as a comparison of the model fitting so as to every index.
This study aimed to identify the explanatory capacity and fit of BMI, RPI, and WHR on physical fitness, including jumping, sprinting, change of direction, and aerobic capacity. This is the first study to compare the ability of BMI, RPI, and WHR to predict physical fitness performance in a young adult population.
The most insightful finding was the different trends observed in physical fitness among indexes. In common with previous literature, our results showed that high BMI values are linked to poor performance Nikolaidis, However, RPI showed an inverse relationship which could be explained by the meaning of body shape index.
Then body shape with high BMI values may be identified as lower RPI values. However, with regard to VO 2max, the best results were observed for RPI. Regarding BMI, our findings showed superior results in SJ and CMJ than in RPI and WHR.
Previous studies have shown that BMI is a good predictor of vertical jump performance, indicating that a high BMI decreases the vertical jump height Qin spoorts al. Although there is still insufficient research on the relationship between jump performance and RPI, previous studies have generally perfofmance a better fit when using RPI than BMI or WHR Silva et al.
However, our pperformance did not support this hypothesis. This could be due to differences in the jump test applied i. standing long jumpwhich presents a different force application i. horizontal vector Silva et al. Previous studies have indicated that BMI is a significant predictor of sprint performance Campa et al.
The best predictor for COD also appears to be BMI. Thus, our results are consistent with those of previous studies Campa et al. However, discrepancies remain between studies, as some have identified the RPI as the best predictor of COD Silva et al.
The RPI is associated with better performance in ectomorphs, both in adolescents Silva et al. However, the RPI was also associated with worse performance among ectomorph tennis players Gale-Watts and Nevill, These differences may be attributed to the different characteristics of each sport.
These findings are pefrormance line with previous results Manzano-Carrasco percormance al. Considering the importance of cardiorespiratory fitness levels for health in the young adults males Ortega et al. Furthermore, it has previously been shown that RPI also predict aerobic test performance Thomis et al.
Nevertheless, the results may depend on the type of test performed Nobari et al. Furthermore, considering RPI as a predictor, the best results have been reported in taller adolescents and those with a more linear physique Nevill et al. Finally, the best predictor of VO 2max in the current study was the RPI Sagat et al.
These findings show that the RPI is a good predictor of aerobic capacity. There is still much disagreement regarding the best predictor of performance, and further studies should be conducted before definitive conclusions can be drawn.
ii Body fat has been identified as a moderator of performance Esco et al. iii In addition, the participants were all from a single country; therefore, the results may not apply to participants in other countries or from other ethnic groups.
iv The sample consisted only of male university students.
: WHR and sports performance| Waist to Hip ratio test | Fasting plasma glucose levels and glucose and insulin responses during oral glucose tolerance tests were lower in the athletes. kg fat-free mass These results indicate that long-term aerobic exercise training is associated with enhanced insulin sensitivity and a lower WHR in older individuals. This finding suggests that regular aerobic exercise may prevent the age-associated increase in abdominal obesity and insulin resistance. Abstract The effect of long-term aerobic exercise training on insulin action was determined in older individuals by comparing insulin sensitivity and maximal responsiveness in 11 master athletes [ This test provides a means to monitor training on the athlete's physical development. However, it is not a good predictor of body fat percentage, but it can be used to indicate changes in body composition over time.

Exercise not only helps you reduce your waist-to-hip ratio, but it also strengthens your muscle, bones, ligaments, and tendons, all while burning calories. To decrease your waist-to-hip ratio, it is important to focus on aerobic exercise. Aerobic activities such as jogging, walking, swimming, or biking for 30 minutes a day should be sufficient. Eating well is an important part of maintaining your waist-to-hip ratio. Eating a balanced diet low in saturated fats, refined carbohydrates, and sugar can help reduce body fat, including around the waist area. Eating whole grains instead of refined carbohydrates has been associated with lower levels of abdominal fat. Additionally, getting enough protein can help increase muscle mass, which can help reduce fat levels and thus help with metabolic diseases. Reducing stress levels can have a positive impact on improving waist-to-hip ratio. High levels of stress can contribute to increased levels of cortisol, a hormone that promotes the storage of fat in the abdominal area. Engaging in stress-reducing activities such as meditation, yoga, or deep breathing exercises can help lower cortisol levels and improve overall mental and physical health. Additionally, participating in activities that bring joy and relaxation, such as hobbies or spending time with loved ones, can also be beneficial in reducing stress levels. Additionally, alcohol can also lead to dehydration and water retention, which can further exacerbate abdominal bloating and increase waist circumference. It is recommended to limit alcohol intake to no more than one drink per day for women and two drinks per day for men. It is also important to note that certain alcoholic beverages, such as beer and sweet cocktails, are higher in calories and sugar content, which can also contribute to weight gain and an unfavorable waist-to-hip ratio. Getting enough sleep is crucial for maintaining a healthy waist-to-hip ratio. Studies have shown that lack of sleep can lead to increased levels of cortisol and insulin, which can promote weight gain and a higher waist-to-hip ratio. Prioritizing good sleep hygiene, such as avoiding screens before bedtime and keeping a consistent sleep schedule, can help you get the rest you need. Sugary drinks have been linked to a variety of health problems, including obesity and an increased risk of type 2 diabetes. Therefore, avoiding sugary drinks is a crucial step in improving your waist-to-hip ratio. Replacing them with healthier alternatives such as water, unsweetened tea, or other low-calorie drinks can significantly reduce your calorie intake and promote weight loss. Additionally, drinking water before meals can also help you feel fuller and consume fewer calories, leading to a healthier waist-to-hip ratio. Sitting for extended periods can contribute to weight gain and a higher waist-to-hip ratio. Look for ways to incorporate more movement into your daily routine, such as taking the stairs instead of the elevator, going for a walk during your lunch break, or using a standing desk at work. Regular physical activity can also help improve your waist-to-hip ratio by promoting weight loss and reducing abdominal fat. Processed foods types of foods are typically high in unhealthy fats, added sugars, and calories, all of which can contribute to weight gain and increase your waist-to-hip ratio. Instead, opt for whole, unprocessed foods, such as fresh fruits and vegetables, lean proteins, and whole grains. These types of foods are nutrient-dense and can help you maintain a healthy weight while reducing your risk of chronic diseases associated with central obesity. Body composition testing with a body composition machine is an accurate yet great way to track changes in your waist-to-hip ratio and overall health. It can help you identify areas where improvements in body composition are needed, as well as give you an indication of whether any changes you make to your diet or exercise routine have the desired effect. The body fat calculator machine can also tell you when your weight is within a healthy range and provide you with an accurate measurement of your overall body fat percentage. Body scanner devices can be useful for individuals looking to lose weight, gain muscle mass, or monitor their health over time. Medical professionals also use it to assess the risk of developing certain diseases, such as heart disease or diabetes. By regularly monitoring your body composition, you can ensure that you are taking the necessary steps to ensure a healthy lifestyle and reduce the risk of certain health complications. For instance, a high waist-to-hip ratio is associated with an increased risk of developing chronic diseases, such as diabetes, stroke, and heart disease. By tracking changes in your body composition, you can make informed decisions about your diet and exercise routine to reduce the risk of developing these health complications. What is the Waist-To-Hip Ratio? The turntable will then rotate; meanwhile, your entire body will be scanned for various body compositions, all in a few seconds. Measure your waist at the smallest point with a tape measure. This is your waist circumference. Then measure your hip circumference by wrapping the same tape around the widest area of your hips. Now, divide your waist size by your hip size. As expected, this method is prone to human errors and minor accuracies. What is the ideal waist-to-hip ratio? Effects of High Waist-To-Hip-Ratio on Your Health. Impact on Cholesterol and Blood Sugar Levels. Increased Risk of Diabetes and Heart Disease. Effects of Low Waist-To-Hip Ratio on Your Health. Reduced Risk of Chronic Diseases. Improved Metabolic Health. Enhanced Athletic Performance. Hormonal Imbalances. Weak Immune System. Nutrient Deficiencies. What Lifestyle Changes can Improve the Waist-To-Hip Ratio? Exercise Regularly. Calorie Deficit. Reduce stress levels. Limit alcohol intake. Get enough sleep. Avoid sugary drinks.
