Effect Of 8-Week Online Fitness Intervention on Muscle Strength, Flexibility, Body Composition and Physical-Self Perception

The purpose of this study is to investigate the effectiveness of 8-week online delivered exercise program on actual and perceived physical fitness components.

Study Overview

• Status: Completed
• Conditions: Sedentary Behavior; Body Image; Physical Inactivity
• Intervention / Treatment: Behavioral: Web-Based Physical Fitness Intervention

Detailed Description

Physical fitness is one of the leading concepts of health and well-being at all stages of life. In certain context, individuals tend to engage in prolonged sedentary behaviors, and these contexts are considered sedentary-promoting environments. These environments also detrimental on physical fitness and health. University students and office workers who predominantly engage in sedentary behaviors, such as prolonged sitting and computer-based work, have consistently shown associations with various aspects of diminished physical fitness. The online intervention protocols might be a good alternative for increasing fitness level for those who live or work in highly sedentary settings. Hence, the purpose of this study is to investigate the effectiveness of 8-week online delivered exercise program on actual and perceived physical fitness components. Specifically, body composition measured by DXA, upper body muscular strength, and flexibility are the main focus of this study. Moreover, physical self-perception is also a focus of this study.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Web based intervention group; The web-based intervention group participated in an 8-week exercise program, which consisted of three sessions per week, each lasting approximately 20 to 35 minutes.	Behavioral: Web-Based Physical Fitness Intervention; The exercise program has been designed according to the progressive overload method. Therefore, the volume of the exercise program increased as the weeks progressed. Exercise videos were uploaded to YouTube on Mondays, Wednesdays and Fridays send to participants via a message group to follow the program. The videos featured the experts' explanations of the movements for each exercise.. The equipment that the participants should use in the training sessions was selected from the materials available at home (eg., use of water bottles instead of weight dumbbells). The exercise sessions is divided into 3 parts: warm-up (2-4 min. average), main part (14-19 min. average), cool-down (3-5 min. average). The warm-up includes movements to increase the heart rate and warm up the muscles to be worked on for that session. The main part of the exercise program also included rest breaks when the participants were asked to move and stretch.
No Intervention: Control Group; The control group did not engage in any prescribed exercise protocol.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Push-Up Test	Participants were asked to place their hands flat on the ground under their shoulders, with a straight slanted line on shoulders, back and legs. While performing the test, participants were expected to lowered the torso until the elbows are in line until 90 degrees angle with upper arms and shoulders were parallel to the ground, while the body were lifted up until the arms are straight at the lifting part. Participants were asked to perform push-ups every 3 seconds and an auditory stimulus was utilized, they were instructed to do each repetition with their body moving rigidly in a roughly straight line.	2 months
Curl-Up Test	The participants were told to lay supine on a mat with the knees bent at a 90 degrees angle, the legs spread apart, and the arms completely extended at the sides with the middle finger of both hands contacting a piece of tape. The zero point was marked with the first piece of tape, and a second piece was placed 10 cm away. A metronome was set to 20 repetitions per minute. In time with the metronome, the participant was directed to curl up until his middle finger reached the second piece of tape.	8 weeks
Sit and Reach Test	A sit and reach box (Lafayette Instrument Company, USA) with a scale marked on the upper side were placed against the wall. The participants were seated barefoot, with their legs fully extended and hip-width apart from the testing box. Participants were instructed to slowly reach forward and slide their fingers along the scale on top of the box by placing one hand over the other. The goal was for participants to maintain the position for about 3 seconds with their knees as straight as they could The final position that the participant reaches were recorded to the nearest centimeter and set as the score for the test.	8 weeks
Perceived Body Fat	Perceived body fat is one's own assessment of his or her own body fat. The body fat subscale of Marsh's Physical Self-Description Questionnaire (PSDQ) was used to collect physical self-perception data. The subscale consisted of six items, answered on a 7-point Likert scale. The maximum score that can be obtained from this scale is 42, and the minimum score is 6. The higher scores obtained in the subdimensions represent higher physical self-perception.	8 weeks
Perceived Physical Strength	Perceived physical strength is one's own assessment of his or her own strength. The strength subscale of Marsh's Physical Self-Description Questionnaire (PSDQ) was used to collect physical self-perception data. The subscale consisted of six items, answered on a 7-point Likert scale. The maximum score that can be obtained from this scale is 42, and the minimum score is 6. The higher scores obtained in the subdimensions represent higher physical self-perception.	8 weeks
Perceived Flexibility	Perceived flexibility is one's own assessment of his or her own flexibility. The flexibility subscale of Marsh's Physical Self-Description Questionnaire (PSDQ) was used to collect physical self-perception data. The subscale consisted of six items, answered on a 7-point Likert scale. The maximum score that can be obtained from this scale is 42, and the minimum score is 6. The higher scores obtained in the subdimensions represent higher physical self-perception.	8 weeks
Perceived Physical Health	Perceived physical health is one's own assessment of his or her own health. The physical health subscale of Marsh's Physical Self-Description Questionnaire (PSDQ) was used to collect physical self-perception data. The subscale consisted of eight items, answered on a 7-point Likert scale. The maximum score that can be obtained from this scale is 42, and the minimum score is 8. The higher scores obtained in the subdimensions represent higher physical self-perception.	8 weeks
