Development of a Comprehensive Performance-Testing Protocol for Competitive Surfers

Abstract

Purpose: Appropriate and valid testing protocols for evaluating the physical performances of surfing athletes are not well refined. The purpose of this project was to develop, refine, and evaluate a testing protocol for use with elite surfers, including measures of anthropometry, strength and power, and endurance. Methods: After pilot testing and consultation with athletes, coaches, and sport scientists, a specific suite of tests was developed. Forty-four competitive junior surfers (16.2 ± 1.3 y, 166.3 ± 7.3 cm, 57.9 ± 8.5 kg) participated in this study involving a within-day repeated-measures analysis, using an elite junior group of 22 international competitors (EJG), to establish reliability of the measures. To reflect validity of the testing measures, a comparison of performance results was then undertaken between the EJG and an age-matched competitive junior group of 22 nationally competitive surfers (CJG). Results: Percent typical error of measurement (%TEM) for primary variables gained from the assessments ranged from 1.1% to 3.0%, with intraclass correlation coefficients ranging from .96 to .99. One-way analysis of variance revealed that the EJG had lower skinfolds (P = .005, d = 0.9) than the CJG, despite no difference in stature (P = .102) or body mass (P = .827). The EJG were faster in 15-m sprint-paddle velocity (P \u3c .001, d = 1.3) and had higher lower-body isometric peak force (P = .04, d = 0.7) and superior endurance-paddling velocity (P = .008, d = 0.9). Conclusions: The relatively low %TEM of these tests in this population allows for high sensitivity to detect change. The results of this study suggest that competitively superior junior surfers are leaner and possess superior strength, paddling power, and paddling endurance

Studi Hindcasting Dalam Menentukan Karakteristik Gelombang dan Klasifikasi Zona Surf Di Pantai Uluwatu, Bali

“…Papan selancar bergerak dengan tenaga ombak yang arahnya dikemudikan oleh peselancar (Eurich et al, 2010). Keahlian menjaga keseimbangan membuat peselancar tetap bertahan di atas ombak (Sheppard et al, 2013). Namun, saat bermain olahraga ekstrim ini, peselancar harus tetap waspada dengan segala resikonya (Sotomayor & Barbieri, 2016).…”

Relationship between propulsive force of the arm, body composition and isokinetic muscle strength indicators in surfers

“…These authors concluded that, maximalpaddling performance can be measured reliably both in the laboratory during swim-bench ergometry and in the field in a swimming pool 6 . However, it would seem more appropriate and indeed more practical, to evaluate paddling ability with surfers in the water to provide greater context validity 8 .…”

Effect of Four Weeks Detraining on Strength, Power, and Sensorimotor Ability of Adolescent Surfers

“…Athletes were instructed and verbally encouraged to push against the force plate as hard as possible while holding the bar across their mid-thigh with maximal effort for five seconds. Recently, Sheppard et al [31] have reported excellent reliability [ICC: 0.99 [0.97-0.99] with a percent typical error of measurement of 2.25% in this population. Although Haff et al [15] used instruction to "pull as fast and hard as possible", the current authors observed during pilot trials that "push" was the appropriate instruction for this population.…”
