INTRODUCTION

High Intensive-interval Training (HIIT) New training methodology More efficient than traditional training

Clemente et al, 2011

INTRODUCTION

Acute effect of HIIT are unknow

The aim of this research was to analyze organic acute response in well trained swimmers studying parameters of lactate, heart rate, heart rate variability, isometric strength of arms, rating of perceived exertion and fatigue of central nervous system in a HIT session.

METHODS

14 trained swimmers (16.2±2.6 years, 169.1±10.2 cm, 61.3±9.9 kg)

Pre-Post HIIT session 4x10m/90” + 16x25m/30“

METHODS

Variables

Rating of perceived Exertion (RPE)

Isometric strength

Lactate concentration

Fatigue of CNS

Autonomic modulation

DISCUSSION

The stimulation of anaerobic lactic system causes a higher increase in the lactic tolerance than other traditional methods

Not produce CNS fatigue, short intervals and short rest

Warbuton et al, 2005

DISCUSSION

Large sympathetic nervous system activation and cardiovascular response

Basic for adaptations

Use of biotechnological devices are basic to know organic response and to organice an efficient training
