Comparative efficacy of visuomotor behaviour rehearsal, biofeedback and combined interventions in performance of young athletes in East Coast of Malaysia.
PhD thesis, Universiti Sains Malaysia.
Abstract
The present study was carried out to investigate the significance of
visuomotor behaviour rehearsal (VMBR), if any, on the ideomotor response
related to erroneous performance outcomes identified in the participants.
Identification of intricate relationships between certain physiological;
psychophysiological; psychomotor and physical performance factors was done
among young-adult high-performing athletes of Malaysia. Fifty-two athletes
were recruited and provided with audio-visual feedback related to their erroneous
performance outcomes, followed by an assessment of physiological parameters
(viz. cardiovascular, autonomic measures of arousal) and corresponding
psychological and psychomotor attributes (viz. cognitive flexibility, anxiety,
reaction ability; motor and movement coordination; mood states and emotional
stability) about performance excellence. Electrodermal evaluation of orienting
reflex and electromyography analyses of evoked potential was carried out.
Thereafter all of the participants were introduced to the evaluation of their
movement errors. After that, they were randomly categorized into four groups,
viz. one no-intervention control group; Experimental (Ex.) group I – who
received training of VMBR only; Ex. Group II received training composite
biofeedback training and the participants of Ex. Group III received training of
VMBR along with biofeedback, following an identical training protocol (i.e., 25 min.s/day, 2 days/ week for 20 weeks). Midterm analyses of all of the baseline
variables were done at the end of the tenth week, followed by post-intervention
assessment, which was carried out at the end of the twentieth week. The
sustainable impact of intervention techniques was evaluated by post-follow-up
assessments. The Repeated measure of ANOVA was done to reveal the integral
psychobiological processes underlying unconscious fear of apprehension leading
toward dismal athletic performance. The outcome of this research will identify
the ideal intervention techniques to be applied in improving the cognitively
mediated perceptual-motor skills (for instance, serial skills involved in take-off
and landing actions) in the athletes. A two-way repeated measure of ANOVA
revealed that VMBR training contributed to the improvement of self-esteem,
pleasant effect and resultant high level of emotional flexibility associated with
changes in impulsivity and irritability evident among the athletes. Sc
biofeedback, on the other hand, enhanced psychobiological (autonomic)
competence in the athletes. This improvement was clear among the athletes who
had relatively lower self-esteem; somatization crises (e.g., irritability, headache,
pain, weakness etc.); autonomic startle response; lower extent of pleasantness
and relatively higher extent of suspicious feelings. Apart from that, the
combined intervention of VMBR and Sc biofeedback training was found
effective in faster agility, speed and peak power output among the athletes,
which were not evident in their counterparts in the no-intervention or control
group and other intervention groups as well.
