Prior Exercise and Blood Lactate Concentration

Prior Exercise and Blood Lactate Concentration

Introduction

The study relates to effect of prior exercise on blood lactate concentration. In this context, it is important to note that the maximum values ??of lactate in the blood may indirectly coaches answer the question, at what level they just are anaerobic capabilities of a particular athletes in a particular sport (Seddon, 2001). However, the level of blood lactate concentration as an indicator of anaerobic load (capacity) is identical for different types of physical activities with the same interval and maximal exercise intensity. Therefore, it is imperative and essential to study the role of prior exercise and no prior exercise of long-term specific adaptation to a specific physical activity that ultimately affects the blood lactate concentration (Billat et. al, 2004).

Research Question

Does prior exercise have an effect on blood lactate concentration?

Hypotheses

HO 1: Blood lactate concentration is affected by prior exercise.

HA 1: Blood lactate concentration is not affected by prior exercise.

HO 2: Blood lactate concentration is affected by no prior exercise.

HA 2: Blood lactate concentration is not affected by no prior exercise.

Methods

A few guidelines are set for the study which include no motivation is given to participants, they are not to consume alcohol or caffeine 24 hours prior to this study, they are to wear same kit for each test, any training 48 hours before study must be repeated to ensure similar results, no eating two hours prior to test, participants are allowed to drink water, the diet must remain same/ similar for both tests, the diet must remain same/ similar for both tests and the test will be done using a randomized protocol that is no set allocation for test, like first prior exercise (Mcconnell & Sharpe, 2005).

Measurements

Measurements that are taken in confirmations include the following:

Time - this will be used during the tests using stop watch;

Heart Rate (HR) - this will be used during arm cranking, resting and cycling;

Rate of Perceived Exercise (RPE) - this will be used during arm cranking, resting and cycling;

Blood test (finger prick to test lactate) - this test will be done Prior to arm cranking, after arm cranking, before cycling and after cycling (Lundberg et. al, 2002).

Equipment

Equipment used stop watch/clock, gloves, tissue, wipes, swimming ergometer, RPE scale, Lab coat, sports kit, watt bike, HR polar, capillary tubes and lancets (finger prick).

Familiarization (Arm Cranking & Cycling)

All participants have been familiarized with all procedures. Participants gave consent form and took health screen, they were in no danger.

Study 1 (prior exercise)

To let the lactate build up, height and weight are recorded then before study RPE, HR and blood lactate are recorded before swimming. Swimming is done for 4x1min efforts with 30sec rest between each minute (Whitehead, 2005). Then 5min rests, in last 30sec of rest RPE, HR and blood lactate are measured for the study. Next the 5k cycling time trial is done and last the RPE, HR, blood lactate and time of 5k time trial are ...
