Physical Fitness Responses after Sixteen Weeks of Three Fitness Program Trainings in Untrained Subjects.

The remarkable popularity of fitness trends like high intensity functional training (HIFT), choreographed high intensity classes (CHIC) and resistance (RT) trainings raises the question on their effect on cardio-respiratory, lactate removal rate, endurance and body composition responses. The purpose of this study was to assess and compare these effects. Ninety-five participants were randomly assigned into 16 weeks of these trainings, five sessions/week.

Effect of three fitness programs on strength, speed, flexibility and muscle power on sedentary subjects.

Background: The aim of this study was to research and compare the effect of Crossfit (CF), LesMills (LM) and traditional resistance (TRAD) training program on short performances.

Methods: Participants were assigned randomly into three groups and followed the training sessions allocated at the rate of five sessions/week for 16 weeks. A battery of tests including anthropometric and performance measures were carried out over three sessions: before training (T0), after eight weeks (T1) and sixteen weeks of training (T2).
