Participants were assessed over 30 m with split times on 10 and 20 m. Four pairs of photoelectric cells (Polifemo Light Radio; Microgate®) were used to record the sprint times. The starting position was placed 0.5 m before the first timing gate, and players started when ready eliminating reaction time. Two trials with a rest of 2 min between each sprint were completed, and the fastest time was considered for the subsequent statistical analysis.

Evaluating Sprint Performance with COD

After the linear sprint test, participants performed a total of four sprints with a COD involved. There were two sprints of 10 m (5 + 5 m) and two sprints of 20 m (10 + 10 m) with a COD of 90° (Figure 2 ). Each set of sprints was repeated so that the player changed direction to the right twice and changed direction to the left twice (Hader et al., 2015 ), and 50% of the participants started with their right limb, and the other 50% started with their left limb. A recovery time of 2 min was allowed between each sprint. At the beginning of each sprint, the front foot was placed 0.5 m before the first photocell (Polifemo Light Radio; Microgate®). For the subsequent statistical analysis, the fastest time of each test was chosen.

This test was performed according to the protocol previously described by Mujika et al. (2009) (link). For register the time employed to cover the test, photoelectric cells (Polifemo Light Radio; Microgate, Bolzano, Italy) were used. Two maximal repetitions with 3 min of passive recovery were allowed for each player. Players were required to drive a ball while performing the test. After the slalom section, the ball was kicked under the hurdle while the player cleared it. The player then freely kicked the ball towards either of two small goals placed diagonally 7 m on the left and the right sides of the hurdle, and sprinted to the finish line. The fastest repetition was selected for the further analysis.

Participants were encouraged to complete two maximum sprints of 20 m, with a split at 5 m being allowed a 2 min of passive recovery between attempts. The players started from a standing position, 0.5 m behind the first set of photoelectric cells (Polifemo Light Radio, Microgate, Bolzano, Italy), before running at maximal speed to the second photoelectric cell. The fastest sprint was recorded and the maximum speed was calculated.

Speed and Endurance Assessment Protocol

The speed and endurance test consisted of two trials and was employed to assess the endurance and speed abilities of the athletes. According to Marszalek et al. (2015) (link), athletes began from the seated position behind the start at cone A; afterwards, each athlete shuffled, as quickly as possible, back and forth between cone A and cones B, C, D, E, F, and G, respectively (Fig. 2C ). During the test, athletes were required to touch the base of all the cones.
The time to complete all sprint tests was assessed through tripod-mounted photocells (Polifemo Light Radio, Microgate SRL, Bolzano, Italy) and for each test the best time was recorded.

200-Meter Sprint Performance Analysis

This test was performed on a synthetic running outdoor track (Mondo). Wind conditions were monitored constantly by an Oregon Scientific WMR-918 (Oregon Scientific, Tigard, OR, USA) meteorological station. A mathematical model (Quinn, 2003 ) was used in order to adjust the potential influence of wind on the performance. This mathematical model suggests that a head wind of -2.0 or -1.0 m·s-1 causes a time loss of 0.121 and 0.059 s, respectively, and that a tail wind of +2.0 or +1.0 provides a time gain of 0.112 and 0.056 s, respectively. Only one 200 m trial was performed. The procedures were the same as the aforementioned ones for the 20 m test. Partial times were recorded for each 50 m split. Five pairs of photocells (Polifemo Radio Light; Microgate, Bolzano, Italy) were used for timing. Measurements of CMJ height were taken before the 200 m test. In addition, capillary blood samples for the determination of lactate concentrations (Lactate Pro 2, Arkray, Kyoto, Japan) were obtained from the earlobe before the exercise and 3 min after the completion of the 200 m sprint.

The SQ test was performed in a Smith machine (Multipower Fitness Line, Peroga, Spain) that allowed a smooth vertical displacement of the bar along a fixed vertical path. The velocity values were measured with a linear velocity transducer (T-Force System, Ergotech, Murcia, Spain) providing immediate feedback and saving the data in the program for later analysis. To measure the jump height was used an infrared timing system (Optojump, Microgate, Bolzano, Italy) and sprint times were measured using photocells (Polifemo Radio Light, Microgate, Bolzano, Italy).

For the RSA and COD tests, time was measured using two photocells connected to an electronic timer and placed 1 m above the ground level (Polifemo Radio Light, Microgate, Bolzano, Italy). During the tests, the participants were verbally encouraged to produce maximal efforts.

This endurance test is widely used in rugby for determining aerobic fitness in rugby players, and it consists of performing a 1200-m running shuttle. Female rugby players that participated in this study were asked to run from the 0 to the 20-m line and back to 0 m; then run to 40 m and back to 0 m; then run to the 60-m line and back to the 0 m line. Cones were placed to clearly identify 0, 20-m, 40-m and 60-m lines. The execution of the 20 m–40 m–60 m shuttle is considered one repetition. Athletes had to complete five consecutive repetitions as fast as possible to finish the test [36 (link)]. The test was measured using electronic photocells (Polifemo Radio Light, Microgate, Bolzano, Italy) located at 0-m, and one repetition was realized and used for the subsequent statistical analysis

On the first day two 20 m trials were performed. The sprint trials were recorded by photocells (Polifemo Radio Light; Microgate, Bolzano, Italy), based on a radio impulse transmission system and a reflection system. Runs were performed from a static biped starting position with the start line located 1 m behind the first photocell. The rest of the photocells were placed at 10 and 20 m. The best time of the two 20 m trials was recorded for further analysis. The rest period between trials lasted 3 min. The sprint test (20 m) was conducted on a synthetic running track in an indoor hall.
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.
