Comparison of Plyometric and Resistance Warmup on Running Performance in Athlets
Condition: Sports Physical Therapy
Study type: Interventional

Summary: 
      Background: Active Warm up is one of the best and commonly used techniques in athletes that
      can induce special type of cardiovascular and metabolic changes that can bring the prominent
      change in running performance. Warm up prepares the body to withstand the high intensity
      exercises and improves the athletic performance and reduce the risk of musculoskeletal
      injury.

      Objective: The objectives of study are to compare two types of warm up resistance and
      plyometric warm up in recreational athletes to improve running performance.
    

Detailed description: 
      Warm up is initial practices before starting exercise with usual concept to enhance the
      overall performance generally known as warm up. Often prior to initiate specific sport it is
      recommended to do cardiovascular warm like stretching for at least 10 to 20 minutes. As
      believed by and proven to many sport coaches that warm up decline the risk of musculoskeletal
      injuries, improve player performance in particular sport by helps to upgrade body
      temperature, excel the muscle potential, decrease muscle stiffness as well as resistance,
      regulate muscle contractile units, increase heart rate and blood flow toward muscles,
      increase oxygen saturation, improve and regulate neuro-muscular electrical signals to achieve
      best outcome in competition.

      Types of Warm Up:

      Different types of warm up like active, passive and mixed regimes are generally recommended
      previous to any sport, different researches and studies have been conducted to seek the
      effects of various warm up protocols and their impact on athletes performance. Stretching,
      treadmill walking, plyometric exercises are frequently directed for warm up.

      Plyometric warmup are heavy strength regimes may include works out like jumping, additionally
      called plyometric works out, ordinarily used to expand strength through the
      stretch-shortening cycle (SSC). This sort of preparing is a profoundly successful
      neuromuscular boost, with the benefit of requiring low physical space, time and it also
      require less training equipment to finish the training sittings. Present moment plyometric
      programs positively affect endurance running execution or running economy.

      Resistance training improvement can improve running mechanics. Improved biomechanical
      efficiency and improved joint activation and coordination of leg muscles may enable a
      reduction in relative workload. Improved Running Mechanisms Combining neuromuscular
      efficiency and strength can reduce oxygen consumption and thus improve running economy and
      ultimately performance Indeed, the combination of HRT and plyometric training may facilitate
      further improvements in the running economy through the accumulation of adaptations
      previously observed when any type of training is run alone.

      Previously investigated the effects of short term resistance training program and plyometric
      training on fitness performance in boys aged 12 to 15 years and concluded that plyometric
      training improved the running velocity. A study effect of plyometric training on running
      performance and vertical jumping in prepubertal boys it stated that plyometric training
      programme causes higher muscle tension compared to resistance training and energy is more
      stored and released during muscle shortening for this reason plyometric training is widely
      recommended for improving the running economy. A study was done on The Impact of Resistance
      Training on Distance Running Performance concluded that the running economy improved up to 8%
      with the help of resistance training programme but it improves the running performance in
      only trained runners. Even a small improvement in running economy could have a large impact
      on distance running performance, particularly in longer events, such as marathons or
      ultra-marathon. A study Effects of plyometric training on endurance and explosive strength
      performance in competitive middle- and long-distance runners.
    

Intervention name(s): plyometric warm up group; resistance warm up; control warm up group
Intervention type(s): Other; Other; Other
Intervention description(s): participants will be asked to do 10 minutes self-paced jog on motorized treadmill.
During the plyometric intervention, subjects will perform the 2 * 8 squat jumps, 2 * 8 scissor jumps, and 2 * 8 double leg bounds (2 sets of 8 repetitions) as a part of warm-up, and will have 60 s to recover between each set. Prior to the intervention, participants will be shown the technique to be used during jumping through use of three videos.; participants will be asked to do 10 minutes self-paced jog on motorized treadmill.
After the jog participants will perform the 6*10s strides with the 15% of the weight. Velocity of the strides will be controlled by the participants.
Warmup will be followed by the 10minutes rest; participants will be asked to do 10 minutes self-paced jog on a motorized treadmill.
After the jog participants will perform the 6*10s strides without the weight. Velocity of the strides will be controlled by the participants. Warmup will be followed by the 10minutes rest The total amount of time spended in each of the three warm-up protocols will be recorded. Participants will be instructed to wear the same pair of running shoes during the three tests.
