1 POLAR HEART RATE MONITORING NORTHEASTERN UNIVERSITY STRENGTH AND CONDITIONING

2 WHAT IS POLAR HEART RATE MONITORING? Measures: Heart rate Training load + intensity How hard the athlete is working Calories burned Recovery time-want to see fast recovery

3 HOW POLAR HEART RATE WORKS Athlete wears a transmitter belt with a heart rate monitors on it to tracks his/her heart rate Can see it right while they are exercising or look at it later Works with computer software to track and analyze each athlete Major concept = Training Load Describes amount of stress on an individual from a single workout or over a period of time Training load is more effort than work load Less fit player can be doing more work Example: Very fit player can run more distance in a shorter amount of time, run faster sprints, complete directional change faster, lift heavier weight, etc., than a less fit player so they are doing more work but may have a greater energy expenditure

4 BENEFITS ANALYZE #1 = ensures and promotes safe training Based on data, can adjust training load and intensity, give extra days off to optimize recovery and promote optimal overall performance both on and off the field Provides data analysis to assess training programs Can track all facets of training takes the total picture into account (practice, conditioning, games, etc.) o How much time it takes to fully recover between training sessions/games o Also identify issues in outside variables-if training load is appropriate could be nutrition/stress/sleep/other factors o Avoid over/under training, control workload, compare training load and recovery time, intensity and duration Helps with rehab and weight management Easy way to track goals

5 BENEFITS COMPARE, SHARE, AND KEEP TRACK Compare to previous training Helps to show possible training flaws and ways to fix flaws to achieve peak performance Monitor recovery Progression and regression Promotes open communication based on reliable data between the coach, strength coach, athletes, and colleagues from other colleges Teams as a whole and individual progress (the individual is so important) Individualize some may need more fitness, more recovery time, demands of different sport positions (ex. forward vs. defense) Organized and an efficient way to plan ahead Helps with periodization and creating structure training sessions Follow up with athletes

6 SCENARIOS Coach West (UCONN) (1) too much training during preseason for men s soccer, (2) cumulative loading 1. During the first four days of preseason the team averaged 2400 points (each game is around 350 points) o Equals almost 7 games in four days; training load is too high 2. Cumulative loading (too much loading over an extended duration of time) may not stand out because it happens gradually over a longer period of time = overtraining o Signs athletes complained of fatigue and feeling apathetic; also problems focusing especially with training, restlessness, sleep patterns, sick more than usual, diet changes (more sugar), depression/negative effect on mood o Bad athlete can t perform well, greater risk for injury, decreased performance causes negative self-image, can hurt the team as a whole o For men s soccer, recommended to not go over 90 minutes for a training session

8 RESEARCH Physical demands during an elite female soccer game: Importance of training status Abstract PURPOSE: To examine the activity profile and physical loading of elite female soccer players during match play and to study the relationship between training status and physical match performance. METHODS: Time-motion analysis and HR recordings were performed on 14 elite female soccer players during competitive matches. In addition, the players carried out a laboratory treadmill test and the Yo-Yo intermittent recovery test. RESULTS: The total distance covered during a game was 10.3 km (range: ) with high-intensity running (HIR) accounting for 1.31 km ( ). HIR was performed 125 times (72-159) for 2.3 s ( ) on average. The average and peak HR in a game were 167 beats per minute (BPM) ( ) and 186 ( ), respectively, corresponding to 87% (81-93) and 97% (96-100) of HR(max). Maximal pulmonary oxygen uptake (VO2max) was 49.4 ml/min(-1).kg(-1) ( ), and incremental treadmill test (ITT) performance was 4.49 min ( ). The Yo-Yo test performance was 1379 m ( ). The total distance covered during match play did not correlate with VO2max or ITT performance but correlated with the Yo-Yo test result (r = 0.56, P < 0.05). Significant positive correlations were observed between HIR and VO2max (r = 0.81, P < 0.05), ITT (r = 0.82, P < 0.05), and Yo-Yo test performance (r = 0.76, P < 0.05). No relationship was observed between HR(max) during match play and any of the performance measures. CONCLUSION: The present study demonstrated that 1) HIR during games varies markedly between elite female soccer players, 2) all players have high HR throughout a competitive game with periods of near-maximal values, 3) the distance covered by HIR during match play is closely related to the physical capacity, and 4) the Yo-Yo intermittent recovery test can be used as an indicator of the physical match performance of elite female players.

9 RESEARCH Correlations between injury, training intensity, and physical and mental exhaustion among college athletes The primary purpose of this research was to obtain information concerning injury incidence and perceptions of training intensities and fatigue levels among college athletes via a survey study. A second purpose was to illuminate correlations between the collected data. This study employed an investigator-designed survey instrument administered to 411 NCAA Division II male and female athletes, with 149 completed responses. The survey included 3 themes: injury incidence, training intensity, and physical and mental exhaustion. Men and women spent 4.5 days per week training using moderate- and high-intensity levels. Fifty percent of the total number of athletes reported chronic injury. During the competition season, physical exhaustion occurred frequently and 23.53% of the time with men and women, respectively. In the noncompetition season, physical exhaustion was frequently experienced and 17.65% of the time among men and women, respectively. Statistically significant correlations (p < 0.05) were found with acute injury for men and chronic injury for women. Also, training intensity levels and physical and mental exhaustion for men and women were statistically significant. The current investigators found the training involved 2-3 hours of moderate to high intensity 4.5 days per week both during competition and noncompetition; women and men spent 2-3 hours of light intensity 1.31 and 1.45 days per week, respectively. Women and men in addition to training, engaged in 3.78 and 4.43 hours of leisure physical activity per week. The investigators recommend tapering, periodization, and rest to help avoid overuse syndrome, overreaching, and overtraining that leads to excessive physical and mental exhaustion and injury.

10 RESEARCH Blood Pressure and Heart Rate Response and Metabolic Cost of Circuit Versus Traditional Weight Training Abstract: This study compared metabolic cost and cost:work ratio to blood pressure and heart rate response between circuit and traditional weight training. Subjects (5 M, 3 F) completed one traditional and one circuit weight training workout. [latin capital V with dot above]o2 was measured during workout and recovery. Total work was calculated by summing the vertical work on the weights and limbs. Heart rate was continuously monitored. SBP and DBP were measured during the last 10 set of each leg exercise and once a minute during recovery. Cost:Work ratios were significantly higher for traditional weight training (p = 0.003). However, due to the greater total workload, total metabolic cost was higher for circuit weight training (p = 0.032). Exercise and recovery ratepressure product (RPP) were calculated. Exercise heart rate was significantly higher during circuit weight training. No differences were found in BP response. Exercising RPP was significantly higher during circuit weight training, indicating a higher workload on the heart. This may be an important consideration when recommending weight training programs for persons with cardiovascular complications. (C) 1996 National Strength and Conditioning Association Pichon, C.
