A Study Of The Trio Lift Actions In The Sports Aerobics

In the sports aerobics world championships the evaluation of routine consists of artistic score, execution score and difficulty score. The evaluation rules of artistic score provides that the artistry of routine composition should meet the following requirements: the routine of mixed pair, trio and group asks for three lifts the first and last may be included), each one more or less than three lifts should be taken 0.5 point away; one lift may show different physical figures and formations, but those should be accomplished simultaneously; the athlete may apply the"prohibited move"allowed in the rules; when one lifts two, the lift height should not exceed the head of the two who are standing. Those who violate aforesaid rules will lose score accordingly. Therefore, lift is a vital part of collective routine and an important sign of collective project, embodying the characteristics of aerobics gymnastic as a collective project.The evaluation rules of sports aerobics ask for three lifts as to mixed pair, trio and group. However, there are no specified rules about the following details: the specific move pattern of each lift, the time when the lift appears, the duration of the lift, the number of athletes in the lift, and the frequency variation of the shoulder axis of the top and base. Thus a lot of space is left to the instructor and athlete to compose and accomplish the lifts. This paper analyzes the trios in the 8th, 9th and 10th World Sport Aerobics Championship from these aspects, figuring out the characteristics and regularity, so as to provide the theoretical basis for the faster and better development of lifts. Findings:By the horizontal analysis of the lifts of trio routine in the 8th, 9th and 10th World Sports Aerobics Championship, the author concludes that, six main factors to influence the lift value are the move pattern of the lift, the time when the lift appears, the duration of the lift, the number of athletes in the lift, the frequency variation of the shoulder axis, whether the 3rd lift breaches the rule or not as well as the reason of the breach, among which three factors have especially distinct influence upon the artistic score. They are the move pattern of the lift, the number of athletes in the lift, and the frequency variation of the shoulder axisBy the vertical analysis of the lifts of trio routine in the 8th, 9th and 10th World Sport Aerobics Championship, the author concludes that, the move pattern of the lift has transited from an equilibrium distribution of dynamic lift and static lift to a distribution of dynamic lift as principle and static lift as assistant. In the 10th World Sport Aerobics Championship, dynamic lifts held the obvious advantage.The time when the lift appears shows the innovation that the instructor composes the routine: in the past, the 1st lift appeared at the beginning of the routine by the whole team; now, it appears by a half team after a series of element, movement pattern, transition and linking; as far as the ending move is concerned, most of the team members were composes at the end in the past, yet now a third doesn't appear. All of the above embodied the integration of the lifts and the element, movement pattern, transition and linking.The lifts occupy one tenth of the total time that the entire routines last. The average time of a lift increased from 11.4 seconds in the 8th World Sport Aerobics Championship to 13.5 seconds in the 10th World Sport Aerobics Championship. It shows that the proportion of the lift time is increasing.There are different kinds of lift pattern, for instance, 1 lifts I, I lifts 2, 2 lift 1, with a variation of the base. A complicated innovation is added to the lift, especially when two lift patterns appear in one lift, e.g., 1 lifts 1 and then transits to another one. In this way, the team members support and coordinate mutually, and the lift itself is filled with adventure and innovation. As a result, the impression of fluency and variation is given to the audience, the innovation of lift is shown, the artistic value of the routine is increased.When the lift is accomplished, the frequency variation of the shoulder axis of the top and base is one index of the diversity of lift. The frequency variation of the shoulder axis increased progressively in the 8th, 9th and 10th World Sport Aerobics Championship, demonstrating the tendency that the lift will be more diversified and more innovative. In each championship of the three, the first six teams applied prohibited move in the last lift without exception. However, the pattern of prohibited move was simplex, most frequently applied ones are hands supporting actions and frontal axis turning actions.
