Slide 1 :

Factors affecting peak-performance in the swimming competitions of the Athens Olympic Games Vladimir B. Issurin, Elite Sport Department at the Wingate Institute, Israel

Slide 2 :

Research Team: Vladimir Issurin Leonid Kaufman Gilad Lustig Elite Sport Department of Israel Gershon Tenenbaum Florida State University, USA

Slide 3 :

Plan Introduction Evidence of the Athens OG Factors affecting the peaking Why they didn’t succeed

Slide 4 :

Terminology Peaking - obtaining the best athletic conditions at a particular moment

Slide 5 :

Two approaches to investigate the peaking Evaluation of performance gains during the taper Evaluation of performance gains during the final stage preparation (FSP)

Slide 6 :

Taper’s background: Taper duration – 7-30 days; Sampling: swimmers, cyclists, runners, weightlifters, triathletes; Outcomes: performance improvement of about 1-8% Kubukeli et al., 2002; Mujika et al., 2004

Slide 7 :

FSP – general scope Entry results Target performance Final Stage Preparation FSP prior the Sidney OG – average performance improvement : US swimming team – 0.2%; Australia swimming team – 0.6% Pyne et al.,2004

Slide 8 :

Factors affecting peaking OG 29 days 65 days 132 days 151 days FSP duration USA Italy Germany Australia

Slide 9 :

Factors affecting peaking OG Olympic Trials Olympic criteria Selection’s mode FSP FSP e x a m e s 1) Tough selection 2) Liberal selection

Slide 10 :

Factors affecting peaking Age Youngsters – till 20 yrs; Middle age – 20-24 yrs; Veterans – 25 yrs and more Is it certain age category more favorable? Gender Female sex hormones can reinforce the influence of other hormones (Viru, 1995) Does the athletes’ gender affects the peaking?

Slide 11 :

Factors affecting peaking Distance length 50, 100, 200, 400, 800 and 1500 m Perhaps certain work duration is more favorable for peaking? Swimming strokes Crawl Breaststroke Backstroke Butterfly Medley Is the peaking stroke dependent?

Slide 12 :

Factors affecting peaking Personal athletic ranking Category Rank Medalists 1 - 3 Finalists 4 – 8 Semi-finalists 9 – 16 Other 17 + How the personal athletic rank affects the peaking?

Slide 13 :

Purpose: to examine the achievement of peak-performance by world-class swimmers and to evaluate effects of several factors determining peaking in the Athens Olympic Games.

Slide 14 :

Method Sampling – 301 swimmers; 424 events (212 male and 212 female)

Slide 15 :

Method 9 world–leading teams; 187 swimmers - tough selection 15 National teams; 114 swimmers - liberal selection

Slide 16 :

Method Relative Performance Gain (RPG%) RPG% = entry time – final time/ entry time x 100

Slide 17 :

Method Descriptive statistics Analysis of variance (ANOVA) Linear regression

Slide 29 :

Impact of gender RPG,% 0.8 0.4 0 1 0.2 0.6 Male Female No difference

Slide 30 :

No differences were found with regards to swimming strokes and distance length

Slide 33 :

Impact of immediate pre-Olympic preparation RPG,% 0 -0.2 0.4 FSP of US prior the Athens OG 0.55 -0.2 0.27 0.2 -0.4 FSP of US prior the Sydney OG (Pyne a.o.,2004) -0.5 FSP of Australia prior the Sydney OG (Pyne a.o.,2004) 0.6 FSP of Australia prior the Athens OG

Slide 34 :

Factors affecting performance impairment: (a) emotional strain and anxiety (b) hormonal and metabolic changes induced by emotional and physical stress (c) training insufficiency during the FSP

Slide 35 :

Facts: Each athlete performs better when his/her level of anxiety falls within the "individual zone of optimal functioning“ (Hanin,1997) Only 30 - 45% of competitors obtain their best results under high level of pre-competitive anxiety (Raglin & Hanin,1999)

Slide 36 :

World tendency: Emotional strain and anxiety at the last Olympic events are more pronounced then previously (Weinberg & Gould, 2003; Blumenshtein a.o.,2004)

Slide 37 :

Fact The rational model of hormonal changes suggests the decline of Testosterone level in the mid-season with subsequent increase prior the competition, and opposite dynamics for Cortisol (M. & A. Viru,2000) The increased trait anxiety suppressed excretion of Testosterone during post-exercise recovery (Diamard,89), similarly the Cortisol level is also subjected by psychological stressors (Mujika a.o.,2004)

Slide 38 :

Testosterone Pre-Season Mid-Season End-Season 100% 60% 80% Cortisol Annual hormonal trend by Viru, 2000 Emotional stress

Slide 39 :

Terminology Residual training effect: - retention of changes in the body state and motor abilities after the cessation of training beyond certain time period

Slide 40 :

Training insufficiency during the FSP: : - hormonal perturbations shift metabolic reactions into a direction of anaerobic prevalence and shortening of the aerobic and anabolic training residuals; - this can follow to reduction of aerobic ability, muscle mass and power, which elicit of performance decline

Slide 41 :

Development of aerobic abilities and muscle strength Development of anaerobic (event-specific) abilities Perfection of maximal speed and tactics Residuals Competition Blocks-mesocycles Rational superposition of residual training effects Issurin, Shkliar,2001

Slide 42 :

Emotional strain and competitive activity shorten the training residuals Fact: (Issurin & Lustig, 2004)

Slide 43 :

Development of aerobic abilities and muscle strength Development of anaerobic (event-specific) abilities Perfection of maximal speed and tactics Residuals Competition Blocks-mesocycles Residuals’ superposition transformed by emotional stress Emotional stress

Slide 44 :

Conclusions: The majority of Olympians don’t reach their personal best The FSP, as a crucial stage for the peaking, should be studied, analyzed, and improved The tough selection increases effectiveness of performances
