Incremental Running Velocity Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

The running velocity was initially set at 6 km/h, and then was increased by 2 km/h every 4 min until it reached 10 km/h. Once the running velocity reached 10 km/h, it was increased by 2 km/h every 3 min until it reached 14 km/h. Once the running velocity reached 14 km/h, it was increased by 0.6 km/h every minute until volitional exhaustion. During the test, expired gases were collected and analyzed with an automatic gas analyzer (AE300S; Minato Medical Science Co., Ltd., Tokyo, Japan). The collected data were averaged every 30 s. Heart rate (HR) was measured continuously during the test with a wireless HR monitor (Acculex Plus; Polar Electro Oy, Kempele, Finland).

Post-exercise Skin Temperature and Heart Rate

Check if the same lab product or an alternative is used in the 5 most similar protocols

Skin temperature was assessed at the midpoint of the thigh (50% of the distance between the greater trochanter and patellar tendon) using an NT logger (NIKKISO-THERM, Tokyo, Japan) and HR using a wireless HR monitor (Acculex Plus; Polar Electro Oy, Kempele, Finland). Skin temperature and HR were measured continuously for 3 h after exercise, with data collected every 1 min. Post-exercise HRs reflect sympathetic and parasympathetic nerve activities at rest^{17 (link)}. Physical activity was evaluated between 3 h and 24 h after exercise using an acceleration sensor (Actimaker; Panasonic Electric Works Co., Osaka, Japan).

Evaluating Oxygen Saturation and Heart Rate During High-Intensity and Continuous Exercise

Check if the same lab product or an alternative is used in the 5 most similar protocols

Percutaneous oxygen saturation (SpO₂) was evaluated at sets 1, 5, and 10 during HIT and every 10 min during the continuous exercise session. The data at each point were collected during 15 s using a finger pulse oximeter (Smart Pulse, Fukuoka Denshi, Tokyo, Japan). Heart rate (HR) was continuously recorded during exercise every 5 s using a wireless HR monitor (Acculex Plus; Polar Electro Oy, Kempele, Finland).

Incremental Treadmill VO2max Test Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

Initial running velocity was set at 10 km/hr, and running velocity was increased by 2 km/hr every 2 min until 14 km/hr. Once running velocity reached 14 km/h, it was increased by 0.6 km/hr every 1 min until volitional exhaustion. The first criterion for exhaustion was maintenance of prescribed running velocity. In addition, we have confirmed all subjects met at least two of four criteria (VO₂ plateau, respiratory exchange ratio > 1.10, HR of at least 90% of theoretical maximum, and rating of perceived exertion > 9 (10 scale) before determination of exhaustion. During the test, expired gases were collected and analyzed breath‐by‐breath using an automatic gas analyzer (AE300S; Minato Medical Science Co., Ltd., Tokyo, Japan). The data were averaged every 30 s. Heart rate (HR) was measured continuously during the test using a wireless HR monitor (Acculex Plus; Polar Electro Oy, Kempele, Finland). The VO_2max tests were performed twice in normoxia or hypoxia, and the order of the two repeated VO_2max tests was randomized. Each test was separated by three days.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
