Sport climbing is now seen as part of the climbing population fi tness interesting resource. Th is study clarifi es the relationship between selected conditioning tests, anamnetic data and performance in sport climbing in the climbing trips OS or RP and each points to a relationship between these ways of ascent climbing routes. Study describes the relation between the diff erent standardized tests selected from Eurofi t test set (standing long jump, full forward trunk bend, pull-up hold, manual dynamometry, „fl amingo“ exercise), anthropometric data (body height, body weight, body fat ratio in %) and anamnestic data (length of climbing experience, climbing performance in terms Red Point RP, and On sight OS). Th e dependency measure is expressed by a linear regression with two dependent variables. Th e dependent variables express climbing performance in terms of RP and OS. Th e signifi cant indicators for dependent variable RP in this given regressive model are length of climbing experience, pull-up hold, manual dynamometry and body weight; for the dependent variable OS, these are length of climbing experience, pull-up hold and manual dynamometry. Aft er the application of a linear regression analysis with two dependent variables, the dependency measure between the RP and OS performance was formulated as a partial correlation rp = 0,745.

Abstract This study presents the evaluation of chosen anthropometric and motor parameters in group of female junior competitors throughout the course of 2-year preparation of aerobic gymnastics by means of Z-scores. The observed group consisted of 12 girls (average age at the beginning of observance 14.08 ± 1.19 years). Evaluation of anthropometric (body height, body weight, body mass index, percentage of body fat, acting body weight) and motor parameters (sit-ups in 30 seconds and 60 seconds, pull-ups to bar, modified push-ups, standing long jump, backwards tandem walking, shuttle run 4×10 m, Jacík’s test) was carried out in standard conditions in nine girls at 3-month intervals. It has been confirmed that female probands with higher Z-score of motor parameters together with lower Z-score of anthropometric parameters achieved higher sport performance during the 2-year observance at competitions, with an exception of one such proband.

The aim of the study was to analyze if there is a connection between some anthropometric measrements and a test for assessing aerobic ability in footballers of different age categories. 65 players were subjected to these measurements, of which 25 players aged 13-14 years (pioneers); 20 players aged 15-16 years (cadets) and 20 players aged 17-18 years (juniors). By using standard anthropometric instruments, body height, body weight, median volume of the chest and aerobic endurance were measured using a 20m “shuttle run” test. Using linear regression analysis, it was found that there is no statistically significant effect of anthropometric variables on a variable (20m “shuttle run”) of all three age players. In these ages, obviously some other characteristics have more influence on the manifestation of aerobic ability. The results of the research can be used by experts in the field of sports in further planning and organizing training contents

IntroductionCadets participating in Reserve Officers’ Training Corp (ROTC) at US universities undergo both Army Physical Fitness Test (APFT) and Occupational Physical Assessment Test (OPAT) evaluations prior to commissioning. The current study examined the relationship between ROTC physical training (PT) attendance and performance in the APFT and OPAT, and characterised physical activity of cadets outside of PT.MethodsTwenty-six cadets’ (21 males; age=20.81±2.48 years; height=171.16±8.62 cm; body mass=75.49±13.17 kg; body mass index=25.68±3.37 kg/m2) PT attendance, and diagnostic (week 1) and record (week 13) OPAT and APFT scores were documented. Paired samples t-tests evaluated differences in APFT and OPAT scores between the diagnostic and record tests. Pearson correlations were utilised to determine if a relationship existed between PT attendance and test performance. Participating cadets also completed monthly self-reported physical activity questionnaire (September, October, November); findings were reported using descriptive statistics.ResultsCadets attended 87% of PT sessions between OPAT administrations and 85% between APFT administrations. Cadets significantly improved the following test components: standing long jump (p=0.034), seated power throw (p=0.029), shuttle run (p=0.005), sit-ups (p=0.003) and 2-mile run (p=0.045). A significant, positive correlation was found between PT attendance and APFT sit-ups improvements (r=0.473, p=0.015). Cadets’ frequently reported additional physical activity days per week (range: 2.8–3.1 aerobic, 3.2–3.8 strength/power, 2.9–3.2 core strength/endurance).ConclusionsRegular participation in a single semester of ROTC PT was found to significantly increase cadets’ scores in some, but not all, components of the APFT and OPAT. Self-reported physical activity results indicate that cadets regularly train outside of organised PT.

Background: It is currently believed that protein folding rates are influenced by protein structure, environment and temperature, amino acid sequence and so on. We have been working for long to determine whether and in what ways mRNA affects the protein folding rate. A large number of palindromes aroused our attention in our previous research. Whether these palindromes do have important influences on protein folding rates and what’s the mechanism? Very few related studies are focused on these problems. Objective: In this article, our motivation is to find out if palindromes have important influences on protein folding rates and what’s the mechanism. Method: In this article, the parameters of the palindromes were defined and calculated, the linear regression analysis between the values of each parameter and the experimental protein folding rates were done. Furthermore, to compare the results of different kinds of proteins, proteins were classified into the two-state proteins and the multi-state proteins. For the two kinds of proteins, the above linear regression analysis were performed respectively. Results : Protein folding rates were negatively correlated to the palindrome frequencies for all proteins. An extremely significant negative linear correlation appeared in the relationship between palindrome densities and protein folding rates. And the repeatedly used bases by different palindromes simultaneously have an important effect on the relationship between palindrome density and protein folding rate. Conclusion: The palindromes have important influences on protein folding rates, and the repeatedly used bases in different palindromes simultaneously play a key role in influencing the protein folding rates.

Sprint Ability

Repeated sprint ability (RSA) is typically used for speed-endurance and agility-endurance training and assessment. RSA is preferred as it mimics actual performance during competition. RSA test involves straight sprint and quick turning movements. Thus, the aim of this study is to determine the relationship between height and body weight measurements on RSA performance, as height and weight may influence the mechanical properties of it. Ten male rugby players (body weight 72.99 ± 14.29 kg, height 169 ± 5.55 cm) selected for Perak SUKMA 2018 team were assessed during centralized training ~9 months prior to their competition.  Body weight and height were measured using standard laboratory weight and height scales prior to the RSA test. RSA were hand-timed for 5 repetitions x 2 sets x 60 seconds rest in between repetitions x 5 minutes rest in-between set. The sprints were performed in the evenings, on grass surface with participants wearing full playing attire. Standardized pre-game warm-up and cooling down were performed. Data recorded was analyzed statistically using a t-test comparison for set one versus set two performances. Pearson correlation coefficient was used to analyze the relationship between anthropometric measures and the RSA test. RSA performance has a negative correlation with the athletes’ height (r= -0.233 set 1, r = -0.435 set 2) and body weight (r= -0.556 set 1, r= -0.629 set 2). RSA performance was significantly different between set 1 and set 2 (p=0.001), with set 1 performance better than set 2. Body height and body weight did not influence RSA performance. Athletes involved did not have adequate speed-agility-endurance needed. In practical, selecting athletes based on their body height and body weight with the assumption that taller and heavier athletes may perform better may not be suitable for this kind of sport. On the other hand, using RSA to test and develop the speed-agility-endurance ability for rugby players is suggested.
