It also aimed to investigate the extent of its implementation in sport sciences department and challenges which hamper its effectiveness. The subjects were peer assisters, tutees and the department head. They were selected through purposive sampling technique. Questionnaire, interview and focus group discussions were employed as data gathering instruments. The findings indicated that tutees, peer assisters and the department head have positive perceptions toward peer assisted learning instruction. They perceived that peer assisted instructional approach helps learners to develop their academic achievement, to enhance their social interaction skills and to manage their psychological difficulties. However, the practices were limited to activities such as doing assignments and project works, sharing their learning and studying experience. The da...

Nowadayswhole body vibrations are very basic and optional activities designed to shape and support
physical rehabilitation and neuromuscular activityand specifically athletic performance which is common
in gyms, sports shops, hotels and fitness rooms. But, it’s not a well-known modality for active, inactive
people, and patients in Ethiopia. Indeed, availability of unsupervised vibration training and commercial
provision of vibratory gym materials may led to trainees functional and structural body changes. Thus, this
article aimed to reviews relevant publications reporting the body respond to vibration and delineate
evidence-based implications to current knowledge of the effects of whole body vibration on body
composition and musculoskeletal performance. A systematic literature search was performed in
databases of Science Direct Scopus, and Google Scholar from 2003 to 2018. This review summarizes
that the whole-body vibration has found a positive effect on body fat percentage, muscle, and bone
function. Howe ever body composition can mostly have referenced with whole body vibration induced
lean mass increment. A supervised vibration training given to healthy individuals and patients with
reference to its contra-indications should have ample importance than free direct exposure.Thus, these
findings could serve as a model for fitness trainers, club coaches, health care practitioners to implement
whole body vibration as an exercise-based management intervention. Nevertheless, attention must be
paid to different vibration load effects (i.e. frequency, exposure time, amplitude, and acceleration).In
addition, whole body vibration training with additional low-risk and specific training are more
advantageous.Key words: Body Composition, Musculoskeletal Function, Patient, Whole body vibration
