The purpose of this study was to determine if implementing a heavy DL warm up (PAP) can improve hang power clean (HPC) performance. Secondarily, it was of interest to determine if there was a meaningful relationship between the DL and HPC one repetition maximums (1-RM). Twelve avid recreational lifters participated in the study (female: n=5, age=29.0±3.2 yrs, height= 171.7±11.9 cm, mass=67.9±20.6 kgs and male: n=7, age=28.9±3.6 yrs, height=178.9±7.6 cm, mass=88.4±11.6 kgs). Participants met on three occasions separated by one week. During week 1 participants established a 1-RM DL. Week 2 half of the participants completed 1-RM HPC, while the other half of the participants completed a 1-RM HPC preceded by a PAP warm-up executed with sets of DLs culminating with one set of one repetition at 90% of 1-RM. Week 3 the participants crossed over with respect to performing the PAP warm-up. A paired t-test was used to compare the mean 1-RM HPCs between conditions and a Pearson correlation coefficient (r) was calculated to compare 1-RM DLs with 1-RM HPCs. The 1-RM hang HPC was significantly greater (≈3.0%) following the DL PAP warm-up (p<0.01). The relationship between the 1-RM DL and 1-RM HPC was r=0.96 (p<0.01), where the 1-RM hang power clean was 54% of the 1-RM DL. Within the parameters of this study, a PAP DL warm-up strategy significantly improved HPC performance. Further, there is a very strong positive relationship between maximum HPC and DL performance.

The objective of this study is to evaluate the effect of low-intensity resistance exercise with Blood Flow Restriction (BFR) on hemodynamic parameters in young men. 30 healthy young men whose ages fell within the range from 19 to 24 volunteered to participate in the study. Then, they were randomly placed in three groups of 1-low-intensity resistance exercise with BFR(LI-BFR) with an intensity of 20% 1RM, 3 sets, and 15 repetitions, 2-high-intensity resistance exercise without BFR(HIW-BFR) with an intensity of 80% 1RM, 3 sets, and 10 repetitions,3-control without exercise and BFR. Both exercise groups did squat and front leg exercises three times a week for three weeks. Hemodynamic parameters were measured one week before the first training session and 30 minutes after the last training session. Comparing groups’ means, t-test and ANOVA were used (p<0.05). Data analysis showed that both exercise programs reduced hemodynamic parameters of HR, SBP, RPP and MAP compared with their pre-exercise values (p<0.05). Moreover, after three weeks of training, significant differences were observed between HR and SBP values in all groups (p<0.05). Based on the findings of the present study, hemodynamic parameters reduced 30 minutes after both low-intensity and high-intensity resistant exercises indicating positive effects of resistant exercises on hemodynamic parameters.

The present study is aimed at ascertaining the quality of life experienced by mothers of children with Autistic Spectrum Disorders (ASD) and mothers of children with Specific Learning Disabilities (SLD). The sample consisted of 60 (30 mothers having children with MR and 30 mothers of children with Autistic Spectrum Disorders). The WHOQOL-BREF questionnaire was used to assess the Quality of Life (QOL) of the 60 mothers of children with special needs. Following the administration, four domain scores were obtained. Analysis using t-test, independent measure was used to compare the two means. Significant differences were found between the two groups on all the four domains of the Quality of Life Scale. Thus, mothers of children having ASD had impaired Quality of Life as compared to mothers of children having SLD. These findings indicate that different effect as a consequence of different childhood conditions and also the need to provide adequate parental support when providing intervention to their children with disabilities.

There is growing evidence which suggests that athletes who suffer from injury experience feelings of anger, depressed mood and anxiety. It is also well-investigated that these negative psychological states have an unfavorable impact on the injury rehabilitation. The present paper is an in-depth case study of an athlete who suffered from an injury prior to a major competitive event following which she experienced significant distress – symptoms suggestive of mild depression. As a part of injury management and rehabilitation, Cognitive behavioral intervention was extensively used with the athlete, predominantly focusing on the use of verbal challenges and rational thinking and maintenance of dysfunctional thought diary. The paper also provides case formulation and intricate details of 10 psychological sessions and strategies used to deal with the cognitive distortions. A mental endurance programme, based on the available research was scripted for the athlete to help aid her performance during the competitive event.
