About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Collegiate soccer players aged 18 - 26 years
  • Participants must have at least 2 years of playing experience
  • Participants should be involved in sport-specific training on at least 2 occasions per week and play competitively once per week

Exclusion criteria

  • Lower extremity reconstructive surgery in last 24 months or unresolved musculoskeletal disorder which would prohibit subject to participate in the sport.
  • Participants who are consuming (or had consumed) growth hormone, anabolic steroids or any kind of performance enhancing drugs.

Treatment and study plan

Plyometric exercise

Behavioral

2 sets of 10 ankle hops, 3 sets of 5 hurdle hops, 5 drop-jumps from a height of 50 cm

Heavy resistance exercise

Behavioral

10 single repetitions of back half squats at 90% of 1 repetition maximum

Primary outcomes

  1. Blood lactate level

    Time frame: Measured prior to and after the intervention period (at 1 minute and 10 minute)

    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.

Secondary outcomes

  1. Countermovement jump height

    Time frame: Measured prior to and after the intervention period (at 1 minute and 10 minute)

    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.

  2. 20 m single sprint time

    Time frame: Measured prior to and after the intervention period (at 1 minute and 10 minute)

    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.
