Personal Development Health and Physical Education HSC Enrichment Day 2014 Core 2 Factors Affecting Performance Presentation Overview Focus Question Student Learn To Student Learn About Explain how an elite athlete uses psychology to improve performance in competition • Psychological strategies to enhance motivation and manage anxiety - Concentration/attention skills (focusing) - Mental rehearsal/visualisation/ imagery - Relaxation techniques - Goal setting • Research case studies of athletes from different sports and ascertain the nature of their motivation and the psychological strategies they employ Explain how nutritional supplementation affects the performance of athletes • Supplementation - Vitamins/minerals - Protein - Caffeine - Creatine products • Critically analyse the evidence for and against supplementation for improved performance Explain how characteristics of the learner affect the acquisition of skill • Characteristics of the learner - Personality - Heredity - Confidence - Prior experience - Ability • Describe how the characteristics of the learner can influence skill acquisition and the performance of skills Psychological Strategies Concentration/attention skills (focusing) Mental rehearsal/visualisation/imagery Mental rehearsal/visualisation is the technique of picturing the performance or skill before the execution Increases mind’s familiarity with desired motion Concentration/attention skills is the ability to focus on the task at hand Encourages athlete to adapt to changing situations and block out irrelevant stimuli Improves concentration, achieves optimal arousal, clears mind, provides additional practice Must maintain uninterrupted connection with the task Psychological Strategies Relaxation Techniques Goal Setting Goal setting provides an athlete with reason to persevere with training. Relaxation includes techniques that assist in controlling high levels of arousal Decreases respiration rate, heart rate and blood pressure Improves concentration and increases motivation Includes progressive muscular relaxation, meditation, centred breathing Goals can be short or long term, behavioural or performance focused Provides focus, gives direction, motivates and redirects focus if lost Case Studies http://www.youtube.com/watch?v=0V5ZzXbWuq8&feature=related Johnny Wilkinson http://www.youtube.com/watch?v=YNRQYT8IQDQ&feature=related Michael Jordan Athlete Psychological strategies utilised How might it improve performance? Why is this the case? Johnny Wilkinson (Rugby Union) Michael Jordan (Basketball) Activity 1. Supplementation Vitamins Case For Case Against Supplementation is only required when an athlete is: Undergoing long-term weight loss Intake of excessive quantities of vitamins is not necessary and is potentially dangerous Travelling to countries with different food choices Excessive amounts of Vitamin A and D contribute to joint pain, headaches, nausea, fatigue and reduced appetite Have a pre-existing vitamin or mineral deficiency which cannot be corrected through diet Have a heavy competition schedule that interferes with normal eating Super-supplementation DOES NOT improve performance Supplementation Minerals Iron Case For Helps deliver oxygen to the working muscles and enhances adaptation to endurance training Case Against Supplementation is generally deemed unnecessary because diet can provide adequate levels required. Lack of iron impairs aerobic capacity Calcium Case For Inadequate consumption can weaken bones, increase the risk of stress fractures and inhibit proper muscle functioning, particularly in high impact sports involving running or jumping. Under-consumption of calcium can lead to osteoporosis. Calcium absorption diminishes with age. Female athletes have a higher needs and usually fall short of adequate intake. Case Against Supplementation is generally deemed unnecessary because diet can provide adequate levels required. Supplementation Protein Case For Endurance athletes in training require extra protein to cover a small proportion of energy costs of their training and to assist in the repair and recovery process. NOTE: Research does not support the idea that athletes require massive amounts of protein in their diet. Case Against Increase calcium excretion in urine and increase the risk of osteoporosis. Decrease the intake of vitamins and minerals. Protein cannot be stored like CHO and the processing and filtration of additional urea can interfere with kidney function Increase the risk of certain cancers Supplementation Caffeine Case For Enhances endurance performance because it promotes an increase in the utilisation of fat as an exercise fuel and ‘spares’ the use of limited muscle stores of glycogen. Case Against Caffeine-containing drinks have a diuretic effect cause an athlete to become dehydrated. Impairment or alteration of fine motor control and technique, over-arousal (interfering with recovery and sleep patterns). Excessive caffeine intake can lead to a fast heart rate, excessive urination, nausea, vomiting, restlessness, anxiety, depression, tremors, and difficulty sleeping. Supplementation Creatine Products Case For Case Against Accelerates gains in muscle size and strength. Creatine users may be more susceptible to cramps, muscle spasms and even pulled muscles. There is a 5-8% uptake in anaerobic capacity, especially when performing repeated bouts of high-intensity exercise for 6-60 seconds. Prior creatine loading enhances glycogen storage and CHO loading in a trained muscle Can increase creatine storage by up 25% and in some athletes 50%. A transient increase in body weight during the initial loading week (water). This consistently disappeared during the following 7 days. Extended Response “Supplementation of an athlete’s diet can mean the difference between winning and losing” Vitamins Minerals Protein Caffeine Creatine Activity 3. Characteristics of the Learner CHEAP!!!!!!! Personality Confidence •A set of ideas that influence a person’s behaviour or motivation. There are 4 broad types of personalities • The belief in oneself and their ability to complete a skill Heredity Ability • An athlete may be inherently gifted through hereditary traits and a culmination of the above factors • Refers to the genetic characteristics we inherit from our parents Prior Experience • Previous experiences practicing new skills or sports 1 Minute Madness http://www.online-stopwatch.com/countdown-clock/full-screen/ List hereditary factors that may influence an athlete’s rate of skill acquisition and performance Activity 4. Think, Pair, Share Answers Characteristic How might it influence? Why might it influence? Confidence - Loss of interest in learning and practising the skill. - Increased ability to focus on the task. - Confidence is the belief in oneself and their ability. - It influences motivation, concentration and self esteem. Heredity - Gender may make the athlete more suited physiologically to a specific sport. - Somatotypes may limit an athlete’s performance in a particular sport e.g. endomorph in gymnastics. - Testosterone influences strength and males have higher levels of it. - Body types such as the endomorph have a shape and muscle mass not conducive to gymnastics. Prior Experience - Transfer of skills from a previous sport make it easier to grasp a new one e.g.Tennis and squash. - Incorrect technique may be developed. - When similar skills are required, the neural pathways in the brain have already been established for the skill. - The pathways are difficult to recreate once learned. Ability - Natural coordination allows athlete to excel in hand eye sports e.g. ball sports. - Problem solving skills may hinder game performance. - Ability encompasses confidence, hereditary factors, experience and personality. - Each of the factors influence the rate of learning and the athlete’s motivation. Personality - The eagle may persist with learning a new skill through to mastery. - The peacock may talk about practising but never get around to doing it. - Eagles are driven, have high energy and are often highly motivated. - Peacocks are enthusiastic and good communicators, but often talk about things without doing them.
