Abstract

Athletes at high risk of groin strains in sports such as hockey and soccer often choose to wear shorts with directional compression to aid in prevention of or recovery from hip adductor strains. Large, eccentric contractions are known to result in or exacerbate strain injuries, but it is unknown if these shorts have a beneficial effect on hip adductor muscle activity. In this study, surface electromyography (EMG) of the adductor longus and ground reaction force (GRF) data were obtained simultaneously on 29 healthy individuals without previous history of serious injury while performing unanticipated 45° run-to-cut manoeuvres in a laboratory setting wearing shorts with non-directional compression (control, HeatGear, Under Armour, USA) or shorts with directional compression (directional, CoreShort PRO, Under Armour, USA), in random order. Average adductor activity in the stance leg was significantly lower in the directional condition than in the control condition during all parts of stance phase (all P < 0.042). From this preliminary analysis, wearing directional compression shorts appears to be associated with reduced stance limb hip adductor activity. Athletes seeking to reduce demand on the hip adductors as they approach full return to activities may benefit from the use of directional compression shorts.  相似文献   

The counseling needs of foreign students     

Ajit K. Das  Stephen Y. Chow  Bruce Rutherford 《International journal for the advancement of counseling》1986,9(2):167-174

This paper reports the findings of three studies of the counseling needs of international students at a medium sized University in the Midwestern region of USA. The studies were conducted over a period of five years (1977–83), and provide an historical perspective on the changes in student needs as well as in the programs designed to respond to these needs.  相似文献   

Effect of oral antioxidant supplementation on lipid peroxidation during radiotherapy in head and neck malignancies     

Anissa Kaleemullah Shariff  Sangita R. Patil  Pramod S. Shukla  Ajit V. Sontakke  Anup S. Hendre  Anand K. Gudur 《Indian journal of clinical biochemistry : IJCB》2009,24(3):307-311

The objectives of the present study were to ascertain the variations in the serum levels of malondialdehyde and total antioxidant status, in head and neck malignancies with different stages, with and without oral antioxidant supplementation, before and after radiotherapy, and to validate the protective effects of an antioxidant supplementation during radiotherapy. The pretreatment values of serum malondialdehyde were significantly raised, while that of serum total antioxidant status were significantly declined in all the stages of head and neck malignancies, when compared with the healthy controls values (P<0.001). A significant correlation was observed related to the studied parameters and different stages of the disease. The study suggests that an oral antioxidant supplementation during radiotherapy is an effective mode in reducing oxidative stress. Antioxidant supplementation during radiotherapy may serve as an adjuvant therapy in malignancies offering a protection to normal cells that may further reduce the risk of developing secondary cancers.  相似文献

Establishment of Trimester-Specific Reference Intervals of Serum TSH & fT4 in a Pregnant Indian Population at North Kolkata     

Rituparna Maji  Sukla Nath  Surajit Lahiri  Mita Saha Das  Ajit Ranjan Bhattacharyya  Harendra Nath Das 《Indian journal of clinical biochemistry : IJCB》2014,29(2):167-173

Reference intervals (RIs) of serum thyroid stimulating hormone (TSH) and free thyroxine (fT₄) were determined in 402 healthy pregnant women by enzyme-linked immunosorbent assay (ELISA) technique after partitioning them into three trimesters. The reference population was chosen from a study population of 610 pregnant females by applying strict inclusion and exclusion criteria. The assays were done using proper quality control measures. RIs were calculated from the central 95 % of the distribution of TSH and fT₄ values located between the lower reference limit of 2.5 percentile and upper reference limit of 97.5 percentile value 0.90 confidence intervals for the upper and lower reference limits were also determined. The reference intervals for TSH were 0.25–3.35 μIU/ml for the first trimester; 0.78–4.96 μIU/ml for the second trimester and 0.89–4.6 μIU/ml for the third trimester. Similarly, the reference intervals for fT₄ for first, second and third trimesters were 0.64–2.0, 0.53–2.12 and 0.64–1.98 ng/dl respectively. The values thus obtained varied from those provided by the kit literature. In comparison to our derived reference intervals, the reference data from kit manufacturer under-diagnosed both subclinical hypo- and hyper-thyroidism within our pregnant reference population.  相似文献   

A Comparative Study of Clinical Utility of Spot Urine Samples with 24-h Urine Albumin Excretion for Screening of Microalbuminuria in Type 2 Diabetic Patients     

Chavan VU  Durgawale PP  Sayyed AK  Sontakke AV  Attar NR  Patel SB  Patil SR  Nilakhe SD 《Indian journal of clinical biochemistry : IJCB》2011,26(3):283-289

Twenty-four hour urinary albumin excretion (UAE) is considered as gold standard method for albuminuria measurement, but collection of 24-h urine is inconvenient. The aim of present study was to evaluate whether albumin: creatinine ratio (ACR) and urinary albumin concentration (UAC) in different spot urine samples correlate or not with 24-h UAE for screening of microalbuminuria in type 2 diabetic patients. We collected first morning void (FMV), random urine sample (RUS) and 24-h urine, separately on consecutive days from 104 type 2 diabetic patients. ACR and UAC in each spot urine sample compared with 24-h UAE with regard to Pearson correlation coefficient. Pearson’s correlation of albumin: creatinine ratio (ACR) with 24-h UAE was (r = 0.802 and 0.623) in first morning void (FMV) and random urine sample (RUS), respectively. Pearson’s correlation coefficient of urinary albumin concentration (UAC) compared with 24-h UAE was (r = 0.943 and 0.920), in FMV and RUS, respectively, P < 0.01. Results revealed that values in first morning void (FMV) were better correlated with 24-h urinary albumin excretion (UAE), than the values in random urine sample (RUS). We conclude that the first morning void (FMV) may be able to replace 24-h urine collection, preferably urinary albumin concentration (UAC) in the initial screening of microalbuminuria in diabetic patients.  相似文献   

Counselling people with addictive behavior     

Ajit K. Das 《International journal for the advancement of counseling》1990,13(2):169-177

A general framework for understanding addictive behaviors (involving chemical substances as well as other forms of compulsions) is presented with special reference to excessive drinking, overeating and compulsive gambling. Treatment procedures for each of these problem behaviors are described and some general conclusions drawn for dealing with other forms of addictions.Paper presented at the XIII^th IRTAC Conference at Calgary, August 14–18, 1988.  相似文献   

Vielseitigkeit als Ausbildungsstrategie im leistungssportlichen Nachwuchstraining     

Lenard Voigt  Ajit Singh  Andreas Hohmann 《Sportwissenschaft》2014,44(3):134-152

This paper presents an excerpt from a comprehensive study on the concepts of long-term athlete development. Following a qualitative research methodology and using a hermeneutic-reconstructive procedure the purpose of this paper was to gain insight into expert youth sports coaches’ understanding of the two main trajectories leading to elite performance: early specialization and early sampling. Analysis of the transcribed interviews suggests that the training strategy is primarily the result of a complex decision making process. Additionally, coaches perceived a trend towards early specialization which conflicts with existing considerations of long-term athlete development. The results of this study provide an opportunity to understand the subject of diversification in youth sports and to raise awareness for the problems of practitioners.  相似文献
