A043: Effect Of High-Intensity Interval Training On Lung Function In College Athletics Teaching, Yanzhao Sun

International Journal of Physical Activity and Health

Background/Purpose of the study: In recent years, high-intensity interval training (HIT) has been used mainly by elite athletes as a training method, but little attention has been paid by the scientific community to the fact that HIT can be used as an effective training method to enhance aerobic performance indices. Therefore, this study hypothesized that HIT would enhance respiratory muscle strength and expiratory flow compared to endurance training (ET). This study also aimed to characterize the effects of HIT on the pulmonary system in order to increase scientific and athletic attention to the effects of high-intensity interval training on aerobic …

A060: The Influence Of Off-Load Training On The Lower Limb Strength Asymmetry Of Tennis Students, Zhongqin Zou, Juan Cai

International Journal of Physical Activity and Health

Background: Many studies have shown that interlimb asymmetry is prevalent in various sports. As a highly reactive, one-sided sport, tennis has been shown to have significant left-right differences in grip strength and triceps strength in tennis players. However, playing tennis can also place an uneven mechanical load on the lower extremities. This left-right difference in mechanical load may also result in asymmetrical strength in the lower limbs. Therefore, early and effective interventions are needed to narrow the strength gap between the non-dominant and dominant legs.

Methods: 21 male college tennis students were recruited and randomly divided into OS-ND group, OS-N …

A091: Proprioception And Strength No Longer Correlate With Mediolateral Stability Among Individuals With Functional Ankle Instability, Yanhao Liu, Peixin Shen, Qipeng Song

International Journal of Physical Activity and Health

Background/Purpose: Dynamic stability deficit is one of the strongest risk factors for ankle sprains. Proprioception and strength are crucial for maintaining dynamic stability and preventing sprains during sports and daily activities. The mechanisms by which humans maintain anteroposterior (AP) and medial-lateral (ML) stability are different. The correlations of AP and ML dynamic stability with its two factors, namely, proprioception and strength, may explain the recurrent sprains among individuals with functional ankle instability (FAI). The purpose of this project was to investigate the correlations of AP and ML dynamic stability with proprioception and strength within the two populations.

Method: This was …
