Brief Summary

It is widely accepted that aerobic exercise and strengthen training are the core components of most workout programs. However, there is no clear consensus on whether the order in which the exercises are performed impacts their effectiveness. Therefore, the overarching aim of the study is to understand the optimal order of two types of concurrent training program for 13 weeks by comparing the effectiveness of the training on body composition, predicated maximal oxygen uptake (MaxVO2), dynamic respiratory parameters, and muscle strength in healthy middle-aged people. Methods:Thirty-three moderately-active middle-aged and healthy participants were randomly assigned to the strength+aerobic group (SAG, n = 16) and aerobic+strength group (ASG, n = 17). Body composition, aerobic endurance, respiratory parameters and upper and lower strength were assessed before (pre-test) and after (post-test) a 13-week intervention. The chi-square test and the independent t-test will be used to compare sociodemographic variables between the groups. A 2 x 2 analysis of variance (ANOVA) with repeated measures (group x measurement) will be conducted.

This study will enhance our understanding of the concurrent training effect on muscle composition and strength. These training programs allow for reducing the duration of the training, which can be an important factor in making adults more willing to participate in physical activity.

Study Groups

strength+aerobic group (SAG)

All training sessions began with a 5- to 7-minute warm- up (consisting low-intensity walking and running, and dynamic mobility exercises) and active recovery of 4- to 5-minute (based on stretching and relaxation exercises). Sessions lasted approximately 50 minutes (warm-up and cold down included), with an overall weekly volume of 105-120 minutes.

The circular training method was used in the resistance training phase. During the aerobic training phase, a series of movements from moderate intensity to vigorous intensity was performed.

The RT lasted approximately 20-25 min per session and included two sets of 8-20 repetitions, with a rest interval of 1-2 min. The resistance training program was performed using the circuit training method in which two or three sets were performed. The RT exercises included: squat, barbell bent-over row, overhead press, plank, lateral pull down, triceps push down, barbell curl, leg extension, leg curl, lunge, barbell bench press, crunches etc.

Group Type: ACTIVE_COMPARATOR

therapeutic Exercise

Intervention Type: OTHER

The circular training method was used in the resistance training phase. During the aerobic training phase, a series of movements from moderate intensity to vigorous intensity was performed. The step loading periodization principle was taken into account in both resistance training and aerobic exercises.

The RT lasted approximately 20-25 min per session and included two sets of 8-20 repetitions, with a rest interval of 1-2 min. The RT exercises included: squat, barbell bent-over row, overhead press, plank, lateral pull down, triceps push down, barbell curl, leg extension, leg curl, lunge, barbell bench press, crunches etc.

For the aerobic training: Intensity was established between 50-65% and 80-85% of HRmax for both groups (SAG and ASG). Aerobic training includes walking and running periods and was carried out on a 400 m outdoor track. In periodization, especially 1st-4th.

aerobic+strength group (ASG)

Similar to the active comparator group, but the order of the training reverse.
