The Effect of Six Weeks of Concurrent Training (Endurance-Resistance) on the Performance of the Cardio-Respiratory System in Inactive Young Women
Bibliographic record
Abstract
Introduction: Inactive lifestyle is associated with decreased cardiorespiratory function and increased chronic non-communicable diseases and death. The aim of this study was to investigate the effect of six weeks of concurrent training (endurance-resistance) on the performance of the cardio-respiratory system in inactive young women. Method: In this quasi-experimental study, 16 inactive women of Tehran city were selected in a targeted and available manner and were randomly placed in two control groups [n = 8] and concurrent exercise [endurance and resistance] [n = 8]. After the pre-test [anthropometric tests and gas analyzer], the concurrent exercise group [endurance and resistance] performed the concurrent exercise program for six weeks and three sessions every week, and the subjects of the control group did not have any special exercise. After the six-week training period, measuring anthropometric indices [body mass index [BMI], body fat percentage [PBF], muscle mass [SMM] and hip-to-waist ratio [WHR] and cardiorespiratory indices including [the first ventilatory threshold [VE/VO2], Second ventilatory threshold [VE/ VCO2], maximum oxygen consumption [VO2max], respiratory exchange ratio [RER], heart rate [HR], forced vital capacity [FVC], forced expiratory volume in one second [FEV1], expiratory volume forced in one second to forced capacity [FEV1/FVC] and the ratio of oxygen consumption to heart rate [VO2/HR] was done using in-body device and gas analyzer. The data were analyzed by covariance analysis test at the P<0.05. Results: The results showed that six weeks of concurrent training [endurance-resistance] had no significant effect on the values of VO2max, FEV1, FVC, VE/VO2, VE/VCO2, FEV1/FVC, VO2/HR, HR in inactive young women [P<0.05]. Also, after the training period, there was no difference in BMI, PBF, SMM and WHR indices between the training and control groups [P<0.05]. Conclusion: According to the results of the research, it seems that six weeks of concurrent training [endurance-resistance] does not affect the performance of the cardio-respiratory system in inactive young women.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
