Effects of the Nike ZoomX Vaporfly Next% 2 shoe on long‐interval training performance, kinematics, neuromuscular parameters, running power and fatigue

Abstract

We analysed the effects of the Nike ZoomX Vaporfly (VPF) on long-interval training performance, kinematic parameters, running power and fatigue compared to a traditional running shoe. Twelve well-trained men (mean ± SD: 32.91 ± 7.50 years; 69.29 ± 7.55 kg and 172.73 ± 5.97 cm) performed two long-interval training sessions (5 × 1000 m with 90s recovery period) 7 days apart, with the VPF shoe or a traditional running shoe (CON) in random order. The countermovement jump (CMJ) height was measured before and after the training sessions and heart rate, spatiotemporal parameters, running power and leg stiffness was measured during training sessions. Runningrelated pain was assessed prior and post-24 h of each training session. Long-interval training performance improved 2.4% using the VPF shoe compared to CON (p = 0.009; ES = 0.482).Step length, contact time and leg stiffness were higher (p < 0.05; ES = 0.51, ES = 0.677, ES = 0.356) while flight time was lower (p < 0.001; ES = 0.756) when using VPF. Running power decreased in a similar way in both conditions throughout the training session. Vertical power was significantly higher in the VPF condition (p = 0.023, ES = 0.388). CMJ height decreased in both conditions after training (4.7 vs. 7.2%, for the VPF and control, respectively, p < 0.001; ES = 0.573). Finally, the perceived muscle pain was influenced by the shoe model condition (chisquare 5.042, P = 0.025). VPF shoes improved the long-interval training performance with similar running power, heart rate and neuromuscular fatigue, and reduced subjective perceived muscle pain compared to regular training shoes. Highlights. VPF shoe may improve long-interval training performance in trained runners with the same running power and heart rate. . Lower subjective perceived muscle pain is found with VPF compared to the regular training shoes. . This type of footwear may be used in high-intensity training sessions aiming to increase the training volume at higher intensities with lower associated fatigue.

The Impact of Nike's Social Media Marketing Strategy on Consumer Demand

“…Nike used digital consumption to a large extent to meet the security needs of consumers, based on the consumer payment choice model, consumers prefer to pay in cash, not only because cash is commonly accepted, but also because cash payments are the safest form of payment because there is no risk or technical failure. However, in the broader context of COVID-19, consumers' perceived risk levels can significantly increase [7]. Digital payments can be made easily and quickly, anywhere and anytime.…”

Nike's Marketing Strategy in the Internet Era

“…This paper will provide physical fitness guidance for special groups, strengthen nonmedical and health intervention, establish and improve exercise prescription databases, and promote the application of prescriptions. In fact, since the success of the 2008 Olympic Games, the concept of national health has been quickly formed, forming a wave of sports boom across the country, and the government is also vigorously supporting and supporting the cause of sports [2]. In 2009, the state passed the National People's Physical Health Day, and the Comprehensive Fitness Regulations also took effect on October 1, which clearly stated that all relevant departments should strengthen the publicity of national health knowledge and organize the masses to participate in sports activities.…”

Influence of Running Shoe Longitudinal Bending Stiffness on Running Economy and Performance in Trained and National Level Runners

“…For AFT shoes, previous studies have reported greater RE improvements in highly trained/national runners (sub-32:00 men and 35:30 women for 10 km) (2)(3)(4) than in recreational/ trained runners (~45:00 for 10 km) (5,(18)(19)(20). A recent meta-analysis showed a RE improvement in world-class and amateur runners with the greatest variability of results in the world-class runners (21).…”
