Effects of Lawn Tennis Association mini tennis as task constraints on children's match-play characteristics.

The Lawn Tennis Association's mini tennis (MT) is a modified version of tennis consisting of progressive stages; however, there have been few attempts to evaluate how MT might shape performance behaviours. Here, we examine effects of playing MT on the emergence of children's match-play behaviours in 48 junior tennis players. Performance in 1010 match-play points were filmed and coded across 4 tennis stages (MT Red, MT Orange, MT Green and Full Ball), using a notational analysis system. Recorded performance variables included rally length, first serve percentage and shot type, for the purpose of analysing inter-stage comparisons. Results showed a series of specific adaptations to playing characteristics across the stages, including rally length, shot variety and serve success. MT Red rallies (7.36 ± 6.06) were longer than Full Ball rallies (3.83 ± 2.40), and a higher percentage of forehands were played at MT Red (66.40 ± 8.49%) than at Full Ball stage (45.96 ± 6.47%). Findings suggested that MT stages can afford children more opportunities to develop their skills and elicit different match-play characteristics than Full Ball task constraints. Coaches, therefore, should consider the nature of emergent adaptations when designing practice environments to facilitate learning in young tennis players.

Benefits of exercise with mini tennis in intellectual disabilities: effects on body image and psychopathology.

The present study is aimed at evaluating the efficacy of an introductory mini tennis programme as a therapeutic aid in the psychosocial rehabilitation of participants affected by mild/moderate intellectual disability in semi-residential care.Two groups (N=12) of participants diagnosed with intellectual disability, one of which followed the mini tennis rehabilitation programme, were compared at time t0, t1 (after 2 months) and t2 (after 6 months).Psychopathological status was assessed by means of the Italian version of the Assessment and Information Rating Profile (AIRP). Motor coordination, lateral dominance and body scheme were assessed by means of structured tools.Psychopathological total scores showed a statistically significant decrease in the experimental group in comparison with the control group. A statistical decrease in the group with the mini tennis rehabilitation programme was found also in the anxiety sub-scale while the sub-scales schizophrenia, depression, adjustment disorder, personality problems, somatoform disorders and psychosexual disorders did not reach any statistical difference between groups.A statistically significant increase in the visuo manual coordination was highlighted in the experimental versus the control group. No statistically significant differences were reported with regard to general movement skills, dynamic balance and coordination.In spite of the limitations of this study, the results obtained are encouraging and suggest the potential efficacy of mini tennis as an auxiliary aid in rehabilitation programmes, particularly to improve visuo manual coordination skills and to boost the patient/participants' self esteem. These findings warrant confirmation by further research studies.
