تأثیر شش هفته تمرینات عملکردی با شدت بالا و تناوب جلسات متفاوت بر شاخص‌های عملکردی در دختران جوان غیر فعال

Abstract:The aim of the present study was to investigate the effect of six weeks of high-intensity functional training and frequency of different sessions on performance indicators in inactive young girls. The method of the present research is quasi-experimental with pre-test and post-test design and in terms of research purpose, it was applied research. The statistical population of the study was inactive young girls who voluntarily selected 30 people as a sample and homogenization of the groups was done using individual characteristics such as age, height, and weight and body fat percentage and randomly divided into three groups of 10 people including control, high-intensity and intermittent functional exercise groups were divided. This study includes 6 weeks of HIFT for the target groups. The training program in each session will include 10 minutes of general warm-up, the main exercise and 10 minutes of cooling. The training movements were researcher-made and were targeted to increase oxygen consumption and simulate the daily movements of the large muscles of the body. Because the subjects did not already have a history of HIFT and HIIT training, the training load was gradually increased and 2 weeks of training including three sessions of aerobic training each week with an intensity of 70-40% of maximum heart rate for 15 to 25 minutes and training to perform exercise protocol movements. Before the start of the protocol, research was conducted to prepare the subjects. The HIFT protocol is 20 seconds of high-intensity activity and 10 seconds of rest between movements. The movements were performed in a circle with 10 stations. Each training session includes 10 movement stations, the intervals between training sessions will be one minute. All tests were measured once before the start of the training protocol and once 48 hours after the end of 6 weeks of training. Initial measurements were taken at 12 noon and training protocol was started 48 hours later. Before the tests, one or two sessions of all subjects tested the tests to eliminate the effect of learning and pre-test. First, body composition was measured (drinks and food were avoided 2 hours before the test), and then after warming up, the tests were performed in the order mentioned. To measure the desired parameters, In body composition device, 540 m double tests, sit-ups, electric dynamometer, vertical jump, medical ball throw, Illinois, stork standing balance test, two speeds 36 m, wells test were used. Analysis of variance and Bonferroni post hoc test were used to analyze the data at a significance level of α 050.05. Findings showed that high-intensity and periodic functional exercises had a significant effect on cardiovascular endurance, muscle endurance, lower torso strength, balance, muscle strength, speed, agility and body composition, but did not affect upper torso strength and flexibility. Also, no significant difference was observed between the two experimental groups. As a result, it can be said that functional training improves physical fitness indicators and thus sports performance and daily activities.Keywords: Functional exercises, functional indicators, physical fitness, inactiv, High intensity functional training, frequency of different sessions
