The Biomechanical Advantage Of Key Anthropometric Variables On Aerobic Performance And Perceived Exertion In Adolescent Swimmers.

Abstract

Background/Introduction: The differential training techniques and environment makes swimming an exclusive sport domain having predominant effects on biomechanical, physiological and biochemical ­parameters providing an apt area for dynamic research.

Objectives: To study the effect of anthropometric parameters on aerobic performance and perceived exertion in adolescent swimmers.

Methods: A pilot study, where 52 adolescent elite swimmers (21F and 32M) were assessed for  anthropometric parameters like sitting height, leg length, waist to hip ratio, using standard procedures. Aerobic performance was assessed by analyzing VO2 max and blood lactate levels, modified Borg’s scale was used to assess the rate of perceived exertion. Pearsons correlation was used to study associations between anthromteric measurements and VO2 Max, blood lactate and perceived exeretion.

Results: VO2 max is negatively correlated (-0.03) with Cormic index.

Waist to hip ratio has a strong positive correlation (+0.74) with blood lactate levels.

Conclusions: Adolescents with longer limb lengths have a biomechanical edge over normal peers since they show a better oxygen utilizing capacity and increased aerobic performance, also factors such as increasing waist line and regional fat distribution have a predominant role in the swimmer’s ability to handle exertion.

In conclusion, identification of specific anthropometric variables with optimization of training can help in identifying talent and predict performance. Physical characteristics can be the basis for tailoring programs and strategies for swimming as an individual sport.
