Abstract

Workouts on Freestyler™ board are performed with stretching elastic tubes which are attached to arms and legs. The aim of the study was to investigate the effects of exercises with Freestyler™ elastic tubes of different resistance on heart rate frequency and prediction of energy expenditure. Eleven males (age 23.4 ± 1.1 years; height 181.6 ± 3.1 cm; weight 81.4 ± 4.9 kg) participated in the study. Effort was assessed with measuring heart rate (HR) frequency. To calculate maximum HR frequency (HRmax) an intermittent Fitness test 30-15 (Buchheit, Haddad, Millet, Lepretre, Newton and Ahmaidi, 2009) was used. Predicted energy expenditure was evaluated with Keytel et al. (2005) formula. One-way analysis of variance - repeated measures was used to analyse the effects of exercises with elastic tubes of different resistance. The results shows that both in relative HR frequency (% HRmax) (F(4, 40) = 161, 906; p = .000) and predicted energy expenditure (F(4, 40) = 151, 677; p = .000) there are statistically significant differences when performing exercises with elastic tubes of different resistance. It could be concluded that doing the same exercises with higher and higher resistance elastic tubes on the Freestyler™ board, could increase the % HRmax (from 19% to 43%) and predicted energy exposure (from 33% to 71%), compared to no additional resistance
