Background: A limited number of studies have investigated the effects of circadian rhythm-based running exercise interventions on physical fitness in child athletes. This study aimed to investigate the effects of an eight-week morning and evening running program on lower extremity strength, agility and respiratory function in 10–12-year-old male footballers. Methods: Participants visited the laboratory three times, with one-day intervals before and after the training program. The assessments included maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and the FEV1/FVC ratio. Additionally, agility and functional performance tests (FPTs) were conducted for both the dominant and non-dominant legs. Results: The findings indicated that morning running was more effective than evening running in enhancing respiratory function. Morning running also showed superior results in lower extremity strength tests, particularly in the single-leg (SL) and triple-leg (THD) crossover hop for distance tests (CHDs) and the 6-m timed-hop test (6 m THT). Furthermore, the agility performance of the morning running group was significantly better than that of the evening and control groups. Conclusion: Consequently, morning running interventions had a positive impact on key physical fitness parameters, including respiratory muscle strength, respiratory function, agility, and lower extremity strength in child footballers.

Apaydın, Murat B.; Polat, Metin
Background and Study Aim Material and Methods Results Conclusions There are studies examining the effects of exercise programs on body and blood parameters in sedentary individuals, but there are few studies examining the effects of resistance and cardio exercises in combination. The aim of this study was to investigate the effects of step-aerobic, cardio and resistance training on body composition and blood parameters in sedentary women for 12 weeks. Step-Aerobic, Cardio and Resistance exercises were applied to the volunteers participating in the study for 12 weeks, 3 days a week for 1 hour each. Body weight, body mass index, body fat percentage and body muscle percentage values were determined from body composition measurements before and after the application. Glucose, Vitamin D3, Triglyceride, Cholesterol, High-density lipoprotein and Low-density values were measured from blood parameters. There is no exercise planning was done in the control group. After the exercise program, a significant decrease (p<0.05) in body weight, body mass index, body fat ratio, Glucose, Vitamin D3, Triglyceride, Cholesterol and Low-density values and a significant increase (p<0.05) in High-density lipoprotein and values were determined in the study group. In the control group, no significant change was observed in both body composition and blood parameters (p>0.05). In the this study, it was found resistance, cardio and step-aerobic exercise programs had a positive effect on body composition and blood parameters in sedentary women. In the control group, there is no positive data for the end of the this study and there is no significant change not only body parametres bu also blood measurement in the control group.
