The norm of bioenergetics characteristics of elite and advanced male and female Iranian Badminton players
, , , ,
Volume 9, Issue 2 (10-2011)
Abstract

The purpose of this study was to collect the norm of bio-energetic
characteristics of male and female elite and advanced Badminton players in
Iran based on gender differences. This is a descriptive research of the kind of
normative survey. Statistical population of the research includes all elite and
advanced male and female Badminton players in Iran during 2010 including 128
elite and advanced players, 64 male (mean age 19.92 + 3.4 yr. height 176.53 +
6.13 cm, weight 70.46 + 6.77 kg and competitive experience 9.27 + 2.68 yr) and
64 females (mean age 17.00 + 2.4 yr, height 163.90 + 5.87 cm, weight 56.18 +
5.75 kg and competitive experience 6.27 + 1.55 yr). The statistical sample was
equal to the statistical population. Regarding the specific characteristics and
demands of Badminton, aerobic power, alactic anaerobic power and lactic
anaerobic power were measured. Also based on the distribution of the obtained
scores, frequency tables and percentage points of the players were drawn
based on gender differences in order to collect the related norms, using spss-15
software. Then according to the percentage norm and Likert scale, players'
performance was classified. One sample t test was applied to compare bioenergetic
characteristics of national and world elite Badminton players. The
results of this study indicated that the average aerobic power of Iranian male
and female elite and advanced badminton players, respectively 55/16 and 44/05
ml/kg.min are significantly lower than the values for world male and female elite
badminton players which are 63 and 50 ml/kg.min (p  0.01). also, the average
of sergeant vertical height of Iranian male and female elite and advanced
badminton players accounting for 63 and 48 centimeters are again significantly
lower than the reported values for world male and female elite badminton
players as 75 and 56 centimeters (p  0.01) but lactic anaerobic power of male
and female Iranian elite and advanced badminton players was in a goodsituation. The results of study highlight an urge to review and pay more
attention to designing professional practices in order to improve and develop
the aforementioned factors.

Volume 13, Issue 9 (4-2015)
Abstract

Introduction and aim: The aim of present study was to assess the effect of six weeks Badminton training
on changes of stress and cortisol levels in non-athletic female students. Materials and Methods: In this
study estimated stress of 120 non-athlete students by stress questionnaire (HAD scale). Were measured
Among subjects who had suffered highest stress, 30 subjects with a mean age of 86/2 ± 22 years, height
56/5 ± 163 cm and weight 95/4 ± 57 kg were selected. Cortisol were measured by the bloodletting. The
subjects were divided into two experimental and control groups as homogeneous. But the control group did
not perform any activity. After training protocol variables were measured again in the same conditions. To
estimate the effect of independent variables on the dependent variable of the t-test and the independent ttest
to compare groups with a significance level (p <0/05) was used. Data were analyzed using spss and
Excel software.
Results: The results of this study showed that doing a six-week badminton practice reduces cortisol levels
(p =0.005), and decreasing stress (p =0.03) in the experimental group.
Conclusion: There was significant change in levels of cortisol and stress in experimental group.

Volume 21, Issue 25 (9-2023)
Abstract
The shoulder complex as one of the most moving joints of the body frequently was used by overhead sports athletes. Thus, musculoskeletal screening such as assessment of the range of motion (ROM), and strength variables can be useful to injury prevention strategies and further the development of conditioning and rehabilitation programs. The purpose of this study is to compare selected variables and the ratio of ROM and strength in volleyball, handball, and badminton players. A total of 36 athletes with similar physical characteristics (volleyball: age=26.65±4.56 y, weight=91.07±7.91 kg, height=185.14±12.25 cm; handball: age=27.29±3.12 y, weight=90.11±6.38 kg, height=183.52±9.67 cm, and badminton: age=26.01±4.29 y, weight=87.85±4.59 kg, height=182.38±10.74 cm) were selected to participate in the current study. A Leighton flex meter and hand-held dynamometer were used respectively to measure the ratio of ROM and strength.The results showed that the mean ratio of external(ER) strength to internal (IR) strength and ER ROM to IR ROM were significantly different between the three groups. The post hoc test revealed that badminton athletes had significant differences in all of the measured variables to both volleyball and handball athletes. But there were no differences between volleyball and handball athletes.In conclusion, preseason screening is vital in achieving optimal values on these measures and may reduce future shoulder injuries in overhead athletes.

Investigation of Eight Weeks of Core Stability Exercises on Upper Extremity’s Range of Motion, Balance, and Strength of the Badminton Players

Volume 21, Issue 25 (9-2023)
Abstract
The purpose of this study was to investigate the effect of eight weeks of core stability exercises on upper limb performance based on Y balance test, strength and range of motion of shoulder rotation in badminton athletes. 30 male badminton players were randomly assigned to two control (n=15) and experimental (n=15) groups. The experimental group performed the core stability training program for eight weeks, three sessions a week for 40 minutes, while the control group did not receive any intervention. Measurement of upper limb function was done by Y balance test, and also shoulder strength and internal and external rotation range of motion were measured by handheld dynamometer and goniometer respectively, before and after the intervention. The analysis of the data obtained from the research based on the ANCOVA statistical test showed that there is a significant difference in the average of the Y upper limb balance test between the two control and experimental groups in both dominant and non-dominant hands. which indicates the positive effect of core stability exercises on people's performance in performing the Y balance test (p<0.05); however, no statistical difference was observed in muscle strength and range of motion of external and internal rotation of the shoulder after the intervention. (p < 0.05). It seems that the provision of core stability training programs can be considered with the approach of increasing the performance of the upper limbs and, of course, preventing injuries in badminton players.
