BACKGROUND: The evidence of response to velocity loss cut-off training with similar total repetitions are limited. OBJECTIVE: This study aimed to examine the effects of different velocity loss training protocols after 3 weeks of traditional resistance training protocols on strength and power in trained men. METHODS: Twenty highly trained men partic...

Background: Sprint interval training (SIT) improves maximal aerobic and anaerobic performance, including oxygen uptake (VO2 max ), power output, and sprint performance. This study aimed to investigate the effect of SIT load on V̇O 2max in trained subjects. Methods: SIT was performed twice a week for three weeks by twenty-four trained men (aged:...

The objective of this study was to investigate the effects of free weight and body mass‐based resistance training (RT) on muscle size and thigh intramuscular fat (IMF) in young and middle‐aged individuals. Healthy individuals (aged 30–64 years) were assigned to either a free weight RT group (n = 21) or a body mass‐based RT group (n = 16). Both grou...

Purpose: This study investigated the effect of online home-based resistance exercise training on fitness, depression, stress, and well-being. A total of 67 individuals participated. Of them, 28 participants (13 men and 15 women, average age: 45.1 ± 12.2 years) performed the same exercise training online (n = 17), using Zoom, or in person (n = 11) i...

Purpose The aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphism, which is exclusive to the Asian population, is related to many diseases. A high reactive oxygen species production in mitochondria, and low muscle strength in athletes and non-athletes, has been observed, as our previous study demonstrated. The purpose of this research was to investig...

Background: In this study, we examined the Sex difference of the effect of rest intervals on lifting velocity during resistance exercise. Methods: Twenty-two trained subjects (11 men and 11 women) were included. Each protocol consisted of 3 sets of 10 repetitions at 70% of 1- repetition maximum (1RM) with rest intervals of 90 s (R90), 150 s (R15...

Purpose: In this study, we examined sex differences in lifting velocity and blood lactate concentration during resistance exercise using different rest intervals (RIs). Methods: Twenty-two trained men (n = 11) and women (n = 11) completed different RIs resistance exercise sessions (90s (R90), 150s (R150), and 240s (R240)). All sessions consisted of...

A specialized training machine, known as a rowing machine or kayak ergometer is used for kayak paddler's indoor training. However, conventional ergometers do not focus on accurately reproducing the feeling of paddling resistance experienced in kayaking on the water, hence kayak paddlers have a risk of learning a paddling form specific to the ergome...

Online exercise is undoubtedly useful and important; however, chronic adaptations to online exercise, particularly strength gain, muscle hypertrophy, and cardiovascular parameters, remain unclear. We investigated the effect of online exercise training using Zoom on fitness parameters compared with the same exercises supervised directly. In the pres...
