Aims and Objectives
Use of electrical stimulation for the gain in these attributes dates back to 1960.But the entire all the protocol for increase in aerobic efficiency of the muscle are unrealistic in approach as they are long duration. One of the short duration electrical stimulation study reported significant changes at the histological level of the muscle. Does the alterations induced by electrical stimulation at histological level of muscle is also reflected back in better aerobic conditioning of the muscle? This study is an attempt to find the answer to this question.
RESEARCH DESIGN
An experimental study was done with a different subject design.
METHOD
35 healthy untrained males and females were selected. [20 males, 15 females] A standardized exercise test on a cycle ergometer was performed. Gas exchange data was collected continuously using an automated breath by breath system (Vista Turbo Trainer, Vacumed, CA, U.S.A.) to determine Ventilation VE (BTPS), O2 uptake VO2 (STPD), VCO2 (STPD), Respiratory Exchange Ratio (R =VCO2/VO2). Delta Efficiency was calculated using Weir's equation. Ten males and five females were electro stimulated on both quadriceps muscles with a frequency of 50 Hz, rectangular biphasic waveform 1:1 duty cycle, with current intensity comfortable to the subject for a total of 20 min a day, 3 days a week for 4 weeks. Remaining 20 subjects were assigned to a control group. The parameters were again measured after 4 weeks for experimental group.
RESULTS
Experimental Group showed significant increase in Delta efficiency (at p<0.01). Experimental group also showed significant differences in Delta efficiency (at p<0.001) when compared to control group. Intramuscular changes appear to be important factor in determining adaptation to the endurance training. Electrical stimulation program of practical applicability with low number of sessions that too with minimal discomfort to the patient/ athlete can be a successful application in clinical and sports medicine situations.

Foot strike was found to be the important mechanism causing intravascular hemolysis in long distance runners. Factors other than foot strike can also cause hemolysis such as duration of the event, running surfaces, shoe type, race distance temperature and level of exertion. It has generally been assumed that running related injuries are, to some degree, caused by excessive peaks in the impact phase of the ground reaction force and it has been suggested that shock absorbing insoles reduce the magnitude and rate of loading of the peak forces generated at foot strike during running and walking, and reduce the ground reaction forces across the foot. Shoe cushioning may reduce the hemolytic changes occurring in long distance runners but there exist contradictory evidence which necessitates further research in this area. Low surface impact absorption may result in impact related injuries and it has been suggested that shock attenuation properties of a surface may be important in reducing impact related injuries. Previous research suggests that the amount of foot strike hemolysis may or may not be altered by the changes in surface characteristics. The importance of this phenomena is that the iron deficiency status due to foot strike hemolysis with or without anemia can limit the athlete achieving maximum aerobic power and hence the performance. Long distance runners are more prone to this problem, although the problem after a single hemolytic episode unlikely to cause iron loss of clinical significance, a cumulative effect over a course of period will have a significant effect.References

Background : Several studies on traumatic musculoskeletal pain syndromes such as Whiplash associated Disorder (WAD) have identified altered motor control of the cervical muscles during the performance of functional tasks. In chronic pain syndromes cervical muscle dysfunction appears to be a general sign. Postural asymmetries and movement dysfunction have been reported in patients with chronic pain. The objective of this study was to investigate if muscle tension of neck muscles is increased in patients with chronic neck pain. Thus this study compared the neck muscle activation patterns during static and dynamic tasks in patients with chronic neck pain of nontraumatic origin.
Methods: Electromyographic activity was recorded from the Sternocleidomastoid(SCM), Anterior Scalene(AS), Levator Scapulae(LS) and Upper Trapezius(UT) muscles. Percentage Maximum voluntary Isometric Contraction (MVIC) was calculated both during static tasks, which included shoulder abduction to 90° and hold, shrug and hold, craniocervical flexion and hold and a dynamic task.
Result: The results revealed elevated muscle activity in AS, LS and UT muscles during both static and dynamic tasks in patients with chronic neck pain of nontraumatic origin compared to controls.
CONCLUSION: In conclusion, patients with chronic neck pain of non-traumatic origin have increased muscle activity and hence increased muscle tension, which is responsible for postural asymmetries. Thus this increased muscle tension should be the focus of treatment.
