Abstract

The purpose of this study is to investigate the effects of training load in tethered swim using three different intensities, on acute and chronic responses of physiological parameters, biochemical and autonomic swimmers. Twenty swimmers aged between 16 and 22 years participated in this study to be divided into two stages. The first phase will aim to determine the acute responses of training sessions in physiological, biochemical, and autonomic. At this stage the assessments will be carried out in five days with a 48 hours minimum interval between each test. The determination of body composition (DEXA) and a maximum 5s effort in tethered swimming in order to determine the maximum force (Fmax) will be held on the first day. The second day will be held in an incremental test tethered swim for the determination of lactate threshold (LT), maximum oxygen uptake (VO2max) and the intensity associated with VO2max (iVO2máx). In subsequent evaluations (third, four and five day) participants will be randomly subjected to three training sessions, with equivalent loads but different intensities (below the LT in LT and iVO2máx). Physiological variables will be evaluated constantly while before during and after each training session and the autonomic and biochemical variables will be collected at the beginning and at the end of each session. The second step will be to investigate the effects of eight weeks training, using different intensities, in physiological biochemical, and autonomic variables. Participants will be divided into two groups that will train at intensities below the LL (GZ1 n = 10) and LL (GZ2 n = 10), with a 7 sessions.weeks-1 frequency. In both groups the training load will be identical and measured by the training impulse (TRIMP). After eight weeks of training, taper process will last for seven days and will be identical for both groups. All variables will be collected at the beginning and end eight.weeks of training and end of taper In phase 1 and 2 the normality and homogeneity of each data will be verified with the Shapiro Wilk test and Levene respectively. Data from Phase 1 will be compared and correlated with the ANOVA (One Way) test for repeated measures and correlated with Pearson, respectively. If necessary Post Hoc Tukey test. In all cases the level of significance will be set at P <0.05.
