The study purpose was to assess the relationship between Latent Myofascial Trigger Point and range of motion in the lower limb of athletes. A lower Pain pressure threshold (< 25 lbs/cm2) in muscles indicates the presence of a latent myofascial trigger point. Materials and methods. Initially, the study involved 46 male Athletes (aged 20-23 years) as participants. The pain pressure threshold was measured by the pressure algometer (FPX 25 Wagner Instruments, Greenwich, CT, USA) to detect latent myofascial trigger points on the hamstring and quadriceps muscles. Out of 46 participants, 23 tested positive with a latent myofascial trigger point, and rest of them tested negative with a latent myofascial trigger point. All the participants measured knee flexor and extensor range of motion with the Kinovea software (version 0.9.5). In descriptive statistics, mean and standard deviation were used, and Pearson correlation was used to determine the relationship between the variables. The level of significance was set at 0.05. Results. A significant correlation was found between Latent Myofascial Trigger Points and lower limb range of motion (p < 0.05), and it was also observed that the magnitude of correlation coefficient was very large (0.7–0.9). Conclusions. Latent Myofascial Trigger Points impair sports performance by decreasing the range of motion of knee flexors and extensors. In light of this, Latent Myofascial Trigger Point should be considered a serious musculoskeletal disorder, and appropriate preventative measures should be taken by health professionals.

The primary objective of this research was to compare red muscle fiber and white muscle fiber muscle architectural parameters of vastus lateralis (VL). The study sample consisted of 70 recreationally active male students from Gwalior, Madhya Pradesh. One repetition maximum Dr. Hatfield test was used to determine muscle fiber type. Thirty (N1 = 15 red muscle fiber group and N2 = 15 red muscle fiber group) out of 70 samples were retained in study for further evaluation. Muscle architectural parameters (VL, pennation angle [PA], fascicle length [FA], and muscle thickness [MT]) were measured using B-mode ultrasonography. Independent sample t-test was employed to determine a significant difference between selected white muscle fibers group and selected red muscle fibers on the basis of selected muscle architectural parameters. The vastus lateralis muscle showed differences in its PA, FA, and MT between different muscle fiber groups. The PA of red muscle fiber group was greater than white muscle fiber group, whereas the FA and MT of white muscle fiber group were greater than red muscle fiber group. In conclusion, architectural parameters studies carried on specific sports group will be helpful in future, and muscle architectural parameters may be considered as a new approach for muscle fiber type classification in the future.

Today there is not a single sport in the world at the competitive level for which resistance training in some or the other form is not used as conditioning exercises. Plyometric training is an excellent method of developing body power and it is proved as a very effective method for improving explosive strength. The purpose of the study was to fi nd out the effects of plyometric exercises on selected motor abilities of university level female basketball players. The subjects, 20 female basketball players of Lakshmibai National Institute of Physical Education, Gwalior, were randomly divided in two groups, that is, experimental and control group. The age of subjects varied between 18 and 22 years. The criterion measures vertical jump, 20-m dash, movement speed, fl exibility and agility in the beginning and at the end of the experimental period of 6 weeks for both the groups. In order to study the effect of plyometric exercises on selected motor abilities, the analysis of co-variance is used at the 0.05 level of signifi cance. It was concluded that the plyometric training is an effective means for improving the following variables: agility, fl exibility vertical jump and movement speed. On the other hand, plyometric training is not an effective means for improving the variable, that is, speed of movement (20-m dash). There was no significant improvement in case of control group. on 12 May 2018 by guest. Protected by copyright.
