The Effects of Mornıng and Evenıng Runnıng on Respıratory Functıon and Lower Extremıty Strength in Pre-Adolescent Male Footballers

Summary

The objective of this study was to examine the impact of eight weeks of morning and evening running on lower extremity strength and respiratory function in 10-12-year-old male soccer players. The participants visited the laboratory 3 times with 1-day intervals before and after the training. The measurements included maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and the FEV1/FVC ratio, agility and functional performance tests (FPTs) for the dominant and nondominant legs. The results of investigators study indicated that morning running was more effective than other forms of exercise in developing the respiratory system. The greatest improvement in FVC, FEV1, MIP, and MEP values was observed in those who performed morning runs (p\< 0.001). The findings of our study indicate that morning running is more effective than running the dominant leg in a series of lower extremity strength tests, including the single leg (SL) and triple leg (THD) crossover hop for distance tests (CHDs) and the 6 m timed-hop test (6 m THT). The results were statistically significant (p=0.000). With respect to the nondominant leg, the SL and 6-meter THT tests were more effective in the morning running group than in the evening running group (p=0.000). The morning running group had better agility performance than the evening and control groups did. As a result, it was determined that morning jogging had a positive effect on respiratory muscle strength, respiratory function and lower extremity strength in children.

RUNNİNG TRAİNİNG

Running training It was performed between 08:00 and 10:00 for morning running and between 18:00 and 20:00 for evening running (Bessot et al., 2014). The exercise intensity of each child in the running group was determined as the 50% heart rate (HR) according to the Karvonen formula (target pulse: (220-age-basal pulse) × intensity) + basal pulse). HR was determined via a telemetric heart rate monitor (PolarM400, Finland) during the first week of running training. Environmental conditions are known to influence the degree of airway epithelial disruption during high-intensity exercise (Boukelia et al., 2017). Therefore, all the participants performed continuous running exercise on a football field in Kelkit/Gümüşhane/Turkey (altitude: 1373 m). It was performed for 50 minutes (including 10 min warm-up and cool-down), 3 days a week, for 8 weeks at the set target heart rate. Each session was supervised by trainers. Running included approximately 10 minutes of warm-up and cool-down with stati
