The aim of this study was to investigate The effect of skill level matching in cooperative dyadic interaction on learning of forehand table tennis skills in adolescent girls. Participants were selected convenience sampling form from 24 junior high school girls in Nahavand city and were randomly divided into two groups of Novice-Novice and Novice-Expert. Both groups performed five sessions of participatory dyad training with their respective arrangement (novice- novice, novice- expert) that each session consisted of 20 sets of 3-minute with a 1-minute rest time between sets. Using table tennis forehand shot accuracy test, the motor performance was measured in the pre-test, post-test, retention and transfer stages (Merely forehand performance with increasing throwing speed of ball thrower). The results showed that both Novice-Novice and Novice-Expert groups showed significant progress learning of forehand table tennis skills; Also, the Novice-Expert performed better in the post-test, retention and transfer stages than the Novice-Novice group. Therefore, Novice-Expert arrangement than Novice-Novice during participatory dyad training facilitates learning forehand table tennis skill.It revealed that novice-expert arrangement is more efficient in comparison to novice-novice arrangement as the former enjoys the benefits of using the optimal observational pattern (seeing a expert person), and offeres various challenges and strategies for the novice partner as a result of exercising with an expert partner. To conclude, novice-expert dyad practice promotes the speed of learning among table tennis learners.

Considering the effect that aerobic exercise can have on cognitive function and memory, the challenge that remains in research is how to schedule timing of these exercises in relation to the acquisition sessions. This study is looking at the question of how aerobic exercise before, during and after acquisition affects the process of consolidating verbal memory. In a semi-experimental design, 48 non-athlete girls aged 20 to 30 years in four groups with different timing (Pre-training, during-training and post-training and control) performed a combination of Ray auditory verbal learning task and 15 minutes of moderate-intensity physical activity. Then, all groups participated in the retention test of memory task one and 24 hours later. The results showed that there was no significant difference between the groups in the trend of changes in the acquisition stage. In addition, the groups performed the same in retention tests. The only difference was observed in the rate of performance decline in the first retention test relative to the end-of-acquisition session, according to which, the control and pre-training groups had a significant decline in performance. Accordingly, it seems that physical exercise during and after acquisition session can have short-term positive effects on verbal memory, although more research is needed to conclude about the effects of timing.Key Words: Aerobic Exercise, Memory Consolidation, Training Timing, Auditory verbal learning, Acquisition
