Effects of Aerobic Training on Improving Health Related Physical Fitness Components among the Postural Deformities of Engineering Students

The word aerobics means "with oxygen". While this definition may sound quite vague, once you have a better understanding of what aerobics actually is, it will make more sense. Aerobic training can be considered any physical activity that has the ability to elevate your heart rate to its target heart rate and maintain that level for a minimum of 20 consecutive minutes. Achieving an "aerobic effect" can be defined as participating in a physical activity that elevates your heart rate to your target heart rate and maintains that level for a minimum of 20 consecutive minutes. For example, an individual that performs a running routine that elevates their heart rate to their target heart rate for 20, or more, consecutive minutes will achieve an aerobic effect.

Aerobics activities can be performed virtually anywhere; from the comfort of your home to a fitness centre, a swimming pool, and even the sidewalk in your neighborhood. For individuals that prefer to perform their aerobic exercise routines at

In addition, one can purchase weight equipment, stationary bikes, elliptical machines, treadmills, exercise balls, and the like for home use as well. Aerobic activities outside of the home include brisk walking, pushing a baby stroller, jogging, swimming, biking, hiking, and becoming a member of a fitness centre. Regularly performing an aerobic activity, and incorporating it into our daily lifestyle, will produce a life that is filled with good health and fitness. The benefits are numerous and far outweigh the effort required to perform the actual exercise. The benefits are associated with regularly performing an aerobic activity you will begin to not only enjoy the times when you exercise, but encouraging others to begin an aerobic exercise routine as well.

For the purpose of the study, altogether fifty engineering students with postural deformities were chosen on random basis from Anna University, Chennai. Their age group ranges from 22 to 25 years. They were divided into two equal groups of 25.The Experimental group I would undergo aerobic training. The second group was Control groups II.Pre – test and post –tests were conducted. Treatments were given for twelve weeks. It would be find out finally the effect of aerobic training on engineering students with postural deformities in scientific methods. The selected tests were measured by following units for testing:

The achieved data were statistically evaluated with dependent t-test to discovery obtainable significant development. The level of significance was secure at 0.05 level of confidence for all the cases.

The procedure adopted in the training programme for the present study is described in the following aspects. started with a warming– up for a period of 10 minutes. During the warming – up the participants was trained to perform aerobic training in a slow manner so that each of the 12 exercises was held for duration of 30 seconds. They performed aerobic training five times. At the end of the class the participants performed relaxation warm down such as stretching for a period of 10 minutes.

The experimental group was given aerobic training after taking an initial test. After the initial test selected aerobic training exercises were given for twelve weeks in 3 days a week. The time of practice was from 7.00A.M to 8.30A.M.The control group was not participating in any of the special training programme. However they were allowed to participate in their regular works.

The effect of independent variables on each criterion variables was considered by dependent„t‟ – test on the data achieved for muscular strength endurance, cardio respiratory endurance, flexibility and body mass index. The pretest and post-test means of experimental group and control group have been analyzed and existing in Table I

The table I, shows that, the obtained ‟t‟–ratio between the pre and post test means of experimental group were 5.74, 3.94, 4.34, 8.12 and control group were 1.09, 1.92, 1.17, 0.71 respectively. The table values required for significant difference with df 24 at 0.05 Level of confidence. Since the obtained „t‟ – ratio value of experimental and control group on were greater than the table value 2.063,it was concluded that the aerobic training had significantly improved Muscular Strength Endurance, Cardio Respiratory Endurance, Flexibility and Body Mass Index of experimental group. The pre and posttest mean value of experimental and control group on muscular strength endurance, cardio respiratory endurance, flexibility and body mass index were graphically represented in the figure 1.

The finding of the study reveals that the aerobic training group cause significant improvement in their health related physical fitness variables. In the view of control group there was no significant improvement in their health related physical fitness J. L.Show, 2006, Reddy, M., 2012, Rosser, M., 2001, Shahana, A., S.N. Usha and S.S. Hasrani, 2010 in their study, they stated that aerobic training developed health related physical fitness variables.

Improvement of on muscular strength endurance, cardio respiratory endurance, flexibility and body mass index was found significantly on experimental group due to the effect of aerobic training when compared to the control group.
