Vascular occlusion has been repeatedly demonstrated to increase muscular strength and hypertrophy when combined with a low-intensity resistance programme. However, to date no investigations have explored the acute effects of force production during vascular occlusion. Therefore, the purpose of this present study aims to examine the acute effects of force production during vascular occlusion on a knee extension exercise. Seven university sport students (meanSD: age 22.7 4.3 years, height 180 5.6 cm, weight 90 10.1 kg) performed an isometric knee extension test at three different knee angles (90 degrees, 60 degrees, and 30 degrees), and an isokinetic knee extension test both with vascular occlusion and without vascular occlusion in a randomised and counterbalanced order. Peak torque (PT), average torque (AVT), time to peak torque (TPT), and work per repetition (WPR) was assessed using a Cybex isokinetic dynamometry (Cybex, NY). The results reported that no significant difference was found in PT (P>0.05), AVT (P>0.05), TPT (P>0.05), and WPR (P>0.05) during vascular occlusion and nonvascular occlusion interventions. Consequently, it appears that there is no significant difference on the acute effects of force production during vascular occlusion on university sport students. However, due to the lack of research on the acute effects of force production during vascular occlusion, these results should prompt further research into the area. From the findings of this research, performance professionals can appreciate that vascular occlusion can be used in specific environments, such as rehabilitation clinics and for the elderly, as low-load resistance training with vascular occlusion has been shown to increase muscular strength and hypertrophy. Introducing low-load resistance training into a professional strength and conditioning environment would be impractical, as vascular occlusion with trained athletes has not been investigated thoroughly enough to suggest increases in muscular strength and hypertrophy, even though there is no evidence that negative effects can happen during vascular occlusion.
