Post - Activation Potentiation After Plyometric and Heavy Resistance Exercise in Soccer Players

Post - Activation Potentiation Following Acute Bouts of Plyometric Versus Heavy Resistance Exercise in Collegiate Soccer Players

The main purpose of this study will be comparison of acute effects of plyometric and heavy resistance exercise on post-activation potentiation

Study Overview

• Status: Completed
• Conditions: Soccer
• Intervention / Treatment: Behavioral: Plyometric exercise; Behavioral: Heavy resistance exercise

Detailed Description

This is a single-center, randomized, crossover study. Collegiate soccer players will be enrolled in this study. The study will be performed in 3 separate sessions.In the first session, participants will be familiarized with the experimental conditions and 1RM will be calculated. Participants will then be randomized to receive either heavy resistance or plyometric exercise first in the second session and then will be crossed over to receive the opposite intervention in the third session. The objective of the study is to compare the acute effects of plyometric and heavy resistance exercise on post - activation potentiation by measuring physical performance and blood lactate level.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Plyometric-Resistance; This group will perform plyometric exercise first and then heavy resistance exercise	Behavioral: Plyometric exercise; 2 sets of 10 ankle hops, 3 sets of 5 hurdle hops, 5 drop-jumps from a height of 50 cm; Behavioral: Heavy resistance exercise; 10 single repetitions of back half squats at 90% of 1 repetition maximum
Experimental: Resistance-Plyometric; This group will perform resistance exercise first and then plyometric exercise	Behavioral: Plyometric exercise; 2 sets of 10 ankle hops, 3 sets of 5 hurdle hops, 5 drop-jumps from a height of 50 cm; Behavioral: Heavy resistance exercise; 10 single repetitions of back half squats at 90% of 1 repetition maximum

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Blood lactate level	Small pinprick blood samples will be taken from fingertip and blood lactate level will be measured by Blood lactate analyser (EKF Diagnostic Lactate Scout +, UK). The area will be cleaned first, using a dry tissue to remove sweat, then an alcohol swab. Once the area is dry, the lancet (often with a spring loaded apparatus) will be used to pierce the skin.	Measured prior to and after the intervention period (at 1 minute and 10 minute)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Countermovement jump height	The countermovement jump height will be measured using an iPhone app 'My Jump'. Jump height will be determined using an acknowledged flight - time calculation. During the CMJ, the subject rest their hands on their hips while performing a downward movement, followed by a maximum effort vertical jump. The subjects have to land in an upright position and to bend knees on landing.	Measured prior to and after the intervention period (at 1 minute and 10 minute)
20 m single sprint time	The 20m single sprint is a standard test for assessing soccer players' running speed. The test involves running a single maximum sprint over 20 meters, with the time recorded using a stopwatch.	Measured prior to and after the intervention period (at 1 minute and 10 minute)
