This study investigated the effect of shoulder, elbow positions with respect to wrist positioned in neutral and in extension in 25 males and 25 females. A hydraulic dynamometer was used to measure the grip strength in six testing positions with respect to wrist positioned in neutral and in extension. The six grip strength tests consisted of three positions in which the elbow was maintained in full extension with varying degrees of shoulder flexion (00, 900 and 1800) and other three positions where the elbow was maintained in 900 flexion combined with varying degrees of shoulder flexion (00, 900 and 1800). Only the dominant hand was tested. The highest mean grip strength score was recorded when the shoulder was positioned in 1800 of flexion with elbow in complete extension with respect to wrist being positioned in neutral (30.20 ± 8.74) and wrist in extension (25.44 ± 7.51), while the lowest mean grip strength score was recorded when shoulder was positioned in 1800 flexion with elbow 900 flexion with respect to wrist being positioned in neutral (21.92 ± 7.45) and wrist in extension (19.40 ± 6.21). Finally grip strength differed significantly for both sexes and study showed males have greater grip strength than females with respect to wrist being positioned in neutral and in extension. In essence, our study affirms that various joint positions can affect grip strength, especially elbow and shoulder joints with respect to wrist positions (neutral and extension). Clinically useful information may be derived from these findings and are valuable in evaluation and rehabilitation training of hand injured patients Key Words: Grip Strength, Hand Strength Testing, Shoulder Position, Elbow Position, Wrist Position

The study was conducted on 14 Haryana state level junior judo players to find out the effectiveness of Russian current stimulation as a recovery modality following exhaustive exercise on heart rate, temperature, blood lactate and blood pressure. Each subject was asked to do 20-m shuttle run test until exhaustion for three times with one week gap in between. After shuttle test, each subject underwent the following three recovery interventions, between 3-33 min, in a systematic random order. Recovery I: passive recovery where the subject was asked to sit for 33 minutes. Recovery II: active recovery where the subject was asked to walk/run at 60% maximal heart rate (MHR) between 3-33 minutes. Recovery III: electrical stimulation where the subject received Russian current (50 hz, 10 sec on: 50 sec off) for 5 min i.e. 3rd to 8th min and 18th to 23rd min of recovery with interspersed 10 min rest in between. Heart rate, temperature, blood lactate, systolic blood pressure, diastolic blood pressure was recorded before the shuttle test and 3rd, 8th, 18th, 23rd and 33rd minutes of recovery period. ANOVA repeated measures (with- in subjects) was used to see the effect of electrical stimulation on physiological parameters in different timings and ANOVA (between subjects) to compare the electrical stimulation with active and passive recovery. Significant level was set at „0.05‟ (p<0.05). Results showed electrical stimulation produced increased heart rate but not significantly, when compared to passive recovery but significantly less when compared to active recovery. Russian current also significantly increased the blood lactate level when it compared to both active and passive recovery values at regular intervals. Active recovery produced significantly lesser body temperature and lactate as well as significantly higher systolic blood pressure when compared to both passive and electrical stimulation modalities. It is concluded that electrical stimulation results in increased blood lactate production without much changes in other physiological parameters.

The purpose of the study was to find out the effect of 12 weeks of interval training with 60-80% intensity for 5-15 repetitions of 400meters on left ventricular end diastolic diameter (LVEDD), left ventricular end diastolic volumes (LVEDV), left ventricular end systolic diameter (LVESD) and left ventricular end systolic volumes (LVESV) of adolescent males. Echocardiographic measurements in athletes should take into account the specific sport and the quantity and quality of training. Sixteen non-residential untrained male subjects (8 Experimental & 8 Control) ranging between 14-16 years were selected for the study. Before the 12 weeks training protocol two-dimensional and Doppler echocardiography was performed for measuring LVEDD, LVESD, LVEDV and LVESV of adolescent boys. Changes in all the parameters were insignificant in case of control group as the initial and final test means yielded lesser values than the tabulated value. The initial and final test means of LVEDD and LVEDV of the experimental group were 44.75cm, 45.5cm and 91.75ml and 95.38ml respectively and the mean difference were insignificant (p>0.05) whereas, „t‟ value of LVESD and LVESV of the experimental group were 3.77 (p <.05) and 3.64 (p <.05) respectively. The result indicates that the 12 weeks interval training was effective for significant reduction of LVESD and LVESV values of the adolescent boys. Key wards: LVEDD, LVESD, LVEDV and LVESV.

In this study, an attempt was made to compare job satisfaction among Physical Education teachers working in different types of schools such as government, private and public schools in the state of Haryana. It was hypothesized that there would be significant difference among government private and public school physical education teachers as regards to their job satisfaction. In order to achieve the objective of the study, Job Satisfaction Scale (JSS) by developed by Singh and Sharma was administered on a sample of total 300 physical education teachers working in the state of Haryana. Out of these, the teachers working in government schools numbered 116 whereas from private and public school category, 92 teachers each were taken for the purpose of the study. Results of the study showed that significant differences in job satisfaction existed among the three categories of the teachers. It was found that government school physical education teachers differed significantly from their counterparts in public schools whereas this difference was not found to be significant between government and private school teachers and also between private and public school physical education teachers.

Upper trapezius trigger point is a common cause for neck pain, decreased cervical range of motion and affects functional activities. The purpose of this study was to compare the effectiveness of Integrated Neuromuscular Inhibitory Technique (INIT) and, Laser with stretching in reducing pain, improving ROM and functional activities of subjects with neck pain due to upper trapezius trigger points. Twenty-two subjects diagnosed with upper trapezius trigger point were included in the study. Seventeen subjects completed the study, in two groups. Group A (7 females, 3 males) received INIT and Group B (6 females, 1 male) received Laser with stretching. The total number of treatment was six days alternatively, within two weeks. The outcome measures were taken before and after treatment. Outcomes were measured by Visual numeric scale, cervical range of motion and neck disability index (NDI).Within the groups the VNS, NDI and cervical lateral flexion showed significant change in the mean value. The comparison of pre and post VNS in Group A, there was a significant reduction in VNS with a p value which was significant (p = 0.005).The pre and post VNS in group B showed a significant reduction in VNS, (p = 0.018), though there was no significant difference in the VNS score between groups (p=.166). The pre and post left lateral flexion (LLF) in Group A and group B showed a significant increase (p = 0.012) and (p = 0.027) respectively. NDI exhibited reduction across both the groups with a significant difference between the groups (p=.045) .This study concluded that both INIT and Laser with stretching are equally effective in managing subjects with neck pain due to upper trapezius trigger point.

The study was aimed at comparing the aerobic capacity in endurance trained and resistance trained athletes. Thirty male athletes who received endurance training and thirty male athletes who received resistance training for a period of more than 1 year were chosen for the study. Physical parameters were measured and exercise stress testing was done on a cycle ergometer with a portable gas analyzing system. Functional capacity (FC) as percentage of predicted V．O2max was measured to study the aerobic capacity. Highly significant (P<0.001) differences existed in values of FC for endurance trained and resistance trained athletes. The higher aerobic capacity displayed by the endurance trained when compared to resistance trained athletes could be due to variations in adaptations that happen in them due to different types of training protocols. The levels of aerobic capacity reported from athletes abroad are higher compared to our athletes and this could prove to be a potential area of improvement for their much awaited superior performance in international arena. Key words: Endurance training, Resistance training, Functional capacity, VO2max.
